3.7 (code name `Indigo`) and 3.8 are bug fixes and stability releases whereas 4.0,4.1,4.2 (code name `Juno`) are new feature set mature platform releases. Release 3.8 and 4.2 are going on simultaneously. You can find more on the eclipse project plans [here][1]. Juno specific plans can be found [here][2].

Eclipse 3.7 or Eclipse Indigo and Eclipse 3.8 are mostly the stable releases where bugs in the previous versions were being corrected. Eclipse always focuses on runtimes, static and dynamic languages; thick-client, thin-client, and server-side frameworks; modeling and business reporting; embedded and mobile; Theses stated features were enhanced and placed with the future releases 4.0,4.1,4.2 also called Eclipse Juno. It had a very mature IDE UI. Eclipse has always been working in enhancing the features given to the Developers to expand their programming knowledge and implementation. To do so the Eclipse Project has been extensively working with a group of multiple teams to build a better IDE than what they have currently. The team always tries to bring in the best with every next release. In the same genre Release 3.8 and Release 4.2 are going on simultaneously. Still the best place to find this info is the place from where even I have referred it [Eclipse Official Website](http://www.eclipse.org/)

I need to implement some functions into an Android application using NDK and thus JNI.

Here&#39;s the C code, with my concerns, that I wrote:

    #include &lt;jni.h&gt;
    #include &lt;stdio.h&gt;
    	
    jobject
    Java_com_example_ndktest_NDKTest_ImageRef(JNIEnv* env, jobject obj, jint width, jint height, jbyteArray myArray)
    {
    	jint i;
    	jobject object;
    	jmethodID constructor;
    	jobject cls;
    	cls = (*env)-&gt;FindClass(env, &quot;com/example/ndktest/NDKTest/Point&quot;);

    //what should put as the second parameter? Is my try correct, according to what
    //you can find in .java file? I used this documentation: http://download.oracle.com/javase/6/docs/technotes/guides/jni/spec/functions.html#wp16027

    	constructor = (*env)-&gt;GetMethodID(env, cls, &quot;&lt;init&gt;&quot;, &quot;void(V)&quot;);
    //http://download.oracle.com/javase/6/docs/technotes/guides/jni/spec/functions.html#wp16660
    //Again, is the last parameter ok?

    	object = (*env)-&gt;NewObject(env, cls, constructor, 5, 6);
    //I want to assign &quot;5&quot; and &quot;6&quot; to point.x and point.y respectively.
       	return object;
    }    
My problems are more or less explained inside the code. Maybe also: is the return type of the function (jobject) ok?

Now the NDKTest.java:

    package com.example.ndktest;
    
    import android.app.Activity;
    import android.widget.TextView;
    import android.os.Bundle;
    
    public class NDKTest extends Activity {
        /** Called when the activity is first created. */
    	public native Point ImageRef(int width, int height, byte[] myArray);
    	public class Point
    	{
    		
    		Point(int myx, int myy)
    		{
    			x = myx;
    			y = myy;
    		}
    		
    		int x;
    		int y;
    	}
    	
        @Override
        public void onCreate(Bundle savedInstanceState)
        {
        	
        	 super.onCreate(savedInstanceState);
             TextView tv = new TextView(this);
             byte[] anArray = new byte[3];
             for (byte i = 0; i &lt; 3; i++)
            	 anArray[i] = i;
             Point point = ImageRef(2, 3, anArray);
             tv.setText(String.valueOf(point.x));
             	setContentView(tv);     
        }
        
        
        
        static
        {
           System.loadLibrary(&quot;test&quot;);
        }
    }

When I try to run the code, it doesn&#39;t work.

How to create an object with JNI?

If I have a input textbox like this:

    &lt;input type=&quot;text&quot; id=&quot;searchField&quot; name=&quot;searchField&quot; /&gt;

How can I set the value of the textfield using javascript or jQuery?

You would think this was simple but I&#39;ve tried the following:

**Using defaultvalue**

    var a = document.getElementById(&quot;searchField&quot;);
    a.value = a.defaultValue;

**Using jQuery**

    jQuery(&quot;#searchField&quot;).focus( function()
    { 
      $(this).val(&quot;&quot;); 
    } );

**Using js**

    document.getElementById(&quot;searchField&quot;).value = &quot;&quot;;

None of them are doing it... :/

I see there are two main distributions of Eclipse going on - One is on 3.6, 3.7, 3.8 path and the other is 4.0, 4.1 path(http://www.eclipse.org/e4/). 

I don&#39;t have clarity on what is the difference between these two distributions?

&gt; **Possible Duplicate:**  
&gt; https://stackoverflow.com/questions/1109022/close-hide-the-android-soft-keyboard

&lt;!-- End of automatically inserted text --&gt;

First thing first I already saw [this][1] thread. I tried the accepted methods given there, but nothing worked for me.

I have two screens in my app.

 - First one has 2 EditText - One for username and one for password
 - Second one have one ListView, and an EditText - to filter the
   listView

**In my first screen, I want username EditText to have focus on startup and the Keyboard should be visible**. This is my implementation (simplified by removing unnecessary/unrelated code).

#app_login.xml

    &lt;LinearLayout android:orientation=&quot;vertical&quot; 
        android:layout_width=&quot;fill_parent&quot; 
        android:layout_height=&quot;wrap_content&quot; 
        android:paddingLeft=&quot;20dip&quot;  
        android:paddingRight=&quot;20dip&quot;&gt;

        &lt;EditText android:id=&quot;@+id/username&quot; 
            android:singleLine=&quot;true&quot; 
            android:layout_width=&quot;fill_parent&quot;  
    	    android:layout_height=&quot;wrap_content&quot; android:hint=&quot;Username&quot;  
            android:imeOptions=&quot;actionDone&quot; android:inputType=&quot;text&quot;
    	    android:maxLines=&quot;1&quot;/&gt;
    
        &lt;EditText android:id=&quot;@+id/password&quot; 
            android:password=&quot;true&quot; 
            android:singleLine=&quot;true&quot;  
    	    android:layout_width=&quot;fill_parent&quot; 
            android:layout_height=&quot;wrap_content&quot;	
    	    android:hint=&quot;Password&quot; /&gt;
    &lt;/LinearLayout&gt;

#AppLogin.java

    class AppLogin extends Activity{
        private EditText mUserNameEdit = null;
        private EditText mPasswordEdit = null;
    
        @Override
        public void onCreate(Bundle savedInstanceState){
            super.onCreate(savedInstanceState);
    	    setContentView(R.layout.app_login);
    		
    	    mUserNameEdit  =	(EditText) findViewById(R.id.username);
    	    mPasswordEdit  =	(EditText) findViewById(R.id.password);
    
            /* code to show keyboard on startup.this code is not working.*/
            InputMethodManager imm =  (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.showSoftInput(mUserNameEdit, InputMethodManager.SHOW_IMPLICIT);
        
        }//End of onCreate()
    }


Well, **the keyboard is not showing at startup**. And my design badly requires a keyboard there.

    
Now on to **second page**. As I already mentioned, I have a listView and EditText there. **I want my keyboard to be hidden on startup only to appear when the user touches the editText**. Can you believe it?  whatever I tried **soft Keyboard is showing when I load the activity**. I am not able to hide it.

#app_list_view.xml

    &lt;LinearLayout android:layout_width=&quot;fill_parent&quot; 
        android:layout_height=&quot;fill_parent&quot; 
        android:orientation=&quot;vertical&quot; &gt;
        
       &lt;EditText android:id=&quot;@+id/filter_edittext&quot;       
            android:layout_width=&quot;fill_parent&quot; 
            android:layout_height=&quot;wrap_content&quot; 
            android:hint=&quot;Search&quot; android:inputType=&quot;text&quot; 
            android:maxLines=&quot;1&quot;/&gt;
        &lt;ListView android:id=&quot;@id/android:list&quot; 
            android:layout_height=&quot;fill_parent&quot;
            android:layout_weight=&quot;1.0&quot; 
            android:layout_width=&quot;fill_parent&quot; 
            android:focusable=&quot;true&quot; 
            android:descendantFocusability=&quot;beforeDescendants&quot;/&gt;
    &lt;/LinearLayout&gt;		

#AppList.java

    public class MyListActivity extends ListActivity{
       private EditText mfilterEditText;
    
    	@Override
       public void onCreate(Bundle savedInstanceState) {	    
          super.onCreate(savedInstanceState);
          setContentView(R.layout.app_list_view);
    
          mFilterEditText  =  (EditText) findViewById(R.id.filter_edittext);
          InputMethodManager imm = InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
          imm.hideSoftInputFromWindow(mFilterEditText.getWindowToken(), 0);
       }
    }


To simplify 

 1. On Login Page (first Page)  I want my keyboard to be visible on startup.
 2. On SecondPage I want the keyboard to be hidden first, only to appear
    when the user touches editText

**And my problem is I am getting the exact opposite on both occasions**. Hope someone faced this issue before. BTW I am testing on the simulator and HTC Desire phone.

#FINAL OUTCOME

Well, I got it working, with the help of all my friends here.

 **1. To Show keyboard on startup**

Two answers worked for me. **One provided by @CapDroid, which is to use a handler and post it delayed..**

    mUserNameEdit.postDelayed(new Runnable() {
      @Override
      public void run() {
        // TODO Auto-generated method stub
        InputMethodManager keyboard = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
        keyboard.showSoftInput(mUserNameEdit, 0);
      }
    },50);

The second answer is provided by @Dyarish, In fact, he linked to another SOF thread, which I haven&#39;t seen before. But the funny thing is that this solution is given in the thread which I referenced at the start. And I haven&#39;t tried
it out because it had zero votes in a thread where all other posts have plenty of votes. Height of foolishness.

    getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

For me, the second solution looked neat, so I decided to stick with it..But the first one certainly works.
Also, @Dyarish&#39;s answer contains a clever hack of using a ScrollView below EditText to give EditText the focus. But I haven&#39;t tried it, but it should work. Not neat though.


 **2. To hide keyboard at activity start**

Only one answer worked for me, which is provided by @Dyarish. And the solution is to use 
focusableInTouchMode settings in XML for the layout containing the EditTexts. This did the trick

    &lt;LinearLayout android:layout_width=&quot;fill_parent&quot; 
        android:layout_height=&quot;fill_parent&quot; 
        android:orientation=&quot;vertical&quot; 
        android:focusableInTouchMode=&quot;true&quot;&gt;
        &lt;EditText android:id=&quot;@+id/filter_edittext&quot;       
            android:layout_width=&quot;fill_parent&quot; 
            android:layout_height=&quot;wrap_content&quot; 
            android:hint=&quot;Search&quot; android:inputType=&quot;text&quot; 
            android:maxLines=&quot;1&quot;/&gt;
        &lt;ListView android:id=&quot;@id/android:list&quot; 
            android:layout_height=&quot;fill_parent&quot;
            android:layout_weight=&quot;1.0&quot; 
            android:layout_width=&quot;fill_parent&quot; 
            android:focusable=&quot;true&quot; 
            android:descendantFocusability=&quot;beforeDescendants&quot;/&gt;
    &lt;/LinearLayout&gt; 


Anyway, I end up using Dyarish&#39;s answer in both cases. So I am awarding the bounty to him. Thanks to all my other friends
who tried to help me.

Consider an example (which compiles in java)

    public abstract interface Interface {
    	public void interfacing();
    	public abstract boolean interfacing(boolean really);
    }

Why is it necessary for an interface to be &quot;declared&quot; abstract? Is there other rules that applies with an abstract interface?

Finally: If `abstract` is obsolete, why is it included in Java? Is there a history for abstract interface?

New to hashtables with a simple question.  For some reason googling hasn&#39;t gotten me a straight answer.  Say I&#39;ve got an `&lt;int,String&gt;` hashtable set up:

    myHashtable.put(1,&quot;bird&quot;);
    myHashtable.put(2,&quot;iguana&quot;);

and I want to change &quot;bird&quot; to &quot;fish&quot; (and leave the index the same).  Can I just do a simple `put`, or do I need to delete the entry, or what?

In  Notepad++ , it has a very nice feature that if I select a word , it will highlight all the same words throughout the text . Added to this , I can set the hot-keys to highlight up to five different  words with different styles (See the effect below) .

![enter image description here][1]

Is there any ways /plug-ins to get this similar effect in eclipse  ? I know when editing Java   , it will highlight all the same variables ,but it will not work when I highlight the comments and editing other files type (e.g. xml, html, js, css and etc).

&gt; localhost.  
&gt; **Multiple contexts have a path of &quot;/FirstApache&quot;.**

I&#39;m working on some applications that, in debug mode, log to the console. I&#39;d like to run and debug them from inside of Eclipse, and view the console for each one simultaneously. However, I have a single Console tab that shows a single Console output at a time. Is there a way I can split the consoles into multiple views so that I can have side-by-side console output?

In Eclipse, can I have multiple Console views at once, each showing a different Console?

I have been doing Java SE for some years now and moving on to Java EE. However, I have some trouble understanding some aspects of Java EE.

1. Is Java EE just a specification? What I mean is: Is EJB Java EE?  

2. Are EJB/Spring different implementations of Java EE?

I am sorry to ask but I have some difficulties to understand what Java EE is.

Can someone please explain what is thread per request and thread per connection? Which model do servlets work on? How threads are allocated to handle HTTP requests? Is it thread/request or connection?

And let&#39;s say if I want to perform a time consuming task in my `Servlet`&#39;s `doGet()` method asynchronously, I start a new thread using Java executors so that lengthy calculations are done in a separate thread and response is sent right away.

Now does that ensure that I have freed the thread which had been processing my `HttpServletRequest` or is it still being used because a child thread is still running?

I tried using the `Toggle mark occurrences (Alt + Shift + O)` button and also in `Preferences -&gt; General -&gt; Editors -&gt; Text Editor -&gt; Annotations` and setting the C/C++ Occurrences and C/C++ Write occurrences.

So the issue is being able to combine multple warning suppressions so that each item doesn&#39;t need it&#39;s own `@SuppressWarnings` annotation.

So for example:

    public class Example
        public Example() {
            GO go = new GO();  // unused
            ....
            List&lt;String&gt; list = ( List&lt;String&gt; ) go.getList(); // unchecked
        }
        ...
        // getters/setters/other methods
    }

Now instead of having two `@SuppressWarnings` I want to have one at the class level for those two warnings, so like this:

    @SuppressWarnings( &quot;unused&quot;, &quot;unchecked&quot; )
    public class Example
        public Example() {
            GO go = new GO();  // unused - suppressed
            ....
            List&lt;String&gt; list = ( List&lt;String&gt; ) go.getList(); // unchecked - suppressed
        }
        ...
        // getters/setters/other methods
    }

But that is not a valid syntax, is there a way to do this?
