The feature is called &#39;Drop to frame&#39; right click on any line in stack, choose &#39;Drop to frame&#39; and you go back to selected method beginning. [Check Eclipse help topic.][1]

Sadly it is not possible to go back to a single line, the JVM does not support this. You can only jump to the start of the current function, as you propably know (Drop to  frame).

It&#39;s not out of beta yet, but [Chronon][c] is a promising debugger that has a &quot;step back&quot; feature.

I am having real trouble trying to deserialize some XML and was hoping someone can offer some assistance. I have read a lot of similar posts but I am unable to resolve this.

**XML I am attempting to deserialize**

    &lt;register-account success=&quot;false&quot;&gt;
      &lt;user-name&gt;xxxxx&lt;/user-name&gt;
      &lt;password&gt;fghgh&lt;/password&gt;
      &lt;email&gt;test@example.com&lt;/email&gt;
      &lt;error&gt;
        &lt;errorcode&gt;120&lt;/errorcode&gt;
        &lt;errormessage&gt;The password is invalid&lt;/errormessage&gt;
      &lt;/error&gt;
    &lt;/register-account&gt;

**Class I am trying to deserialize to:**

    [Serializable, XmlRoot(ElementName = &quot;register-account&quot;, Namespace = &quot;MyNamespace&quot;)]
    [XmlType(&quot;register-account&quot;)]
    public class RegisterAccountResponse
    {
        [XmlAttribute(&quot;success&quot;)]
        public bool Success { get; set; } 
    
        /// &lt;summary&gt;
        /// Gets or sets the Tennant email address
        /// &lt;/summary&gt;

            {
                return null;
            }

            if (data.Trim().Length == 0)

            }

Is there an option to take the stack pointer - or arrow in the debugger, backward and change the current execution line, as in visual studio.  
Today I am using a &quot;workaround&quot; of modifying the source file. this will take me to the beginning of a method, but sometimes it is just not good enough.

I want to access my current working directory using Java.

My code:

     String currentPath = new java.io.File(&quot;.&quot;).getCanonicalPath();
     System.out.println(&quot;Current dir:&quot; + currentPath);

     String currentDir = System.getProperty(&quot;user.dir&quot;);
     System.out.println(&quot;Current dir using System:&quot; + currentDir);

Output:  

    Current dir: C:\WINDOWS\system32
    Current dir using System: C:\WINDOWS\system32

My output is not correct because the C drive is not my current directory.

Is there any way to pass class as a parameter in Java and fire some methods from that class?

    void callClass(???? classObject)
    {

I&#39;ve looked at the other volatile vs. Atomicxxxx questions in SO (including [this one][1]) and have read [the description of java.util.current.atomic][2], and I am not quite satisfied with the nuances.

If I&#39;m trying to decide between using `volatile boolean` and `AtomicBoolean`, are there practical differences besides the atomic read-modify-write operations offered by AtomicBoolean? (e.g. `compareAndSet()` and `getAndSet()`)

Suppose I have

    volatile boolean flag;

Then one or more threads set the flag (but not clear it). If I have one thread that reads the flag, and if set, does an action, and then clears the flag, is `volatile` adequate?

Is there a higher cost to AtomicBoolean than volatile boolean, in terms of

 - memory space
 - performance hit (`volatile boolean` appears to require memory fencing, `AtomicBoolean` appears to require memory fencing + some minor locking on CAS operations as per the java.util.current.atomic description)

My gut call is to just go with AtomicBoolean and be safe, but I want to understand if there&#39;s ever a situation to use `volatile boolean` instead (e.g. if I had thousands of instances of them and performance were an issue).

I have one activity which is the main activity used throughout the app and it has a number of variables. I have two other activities which I would like to be able to use the data from the first activity.
Now I know I can do something like this:

&lt;!-- language: lang-java --&gt;

    GlobalState gs = (GlobalState) getApplication();
    String s = gs.getTestMe();

However I want to share a lot of variables and some might be rather large so I don&#39;t want to be creating copies of them like above.

Is there a way to directly get and change the variables without using get and set methods? I remember reading an article on the Google dev site saying this is not recommended for performance on Android.

What&#39;s the best way to share data between activities?

While testing my apps, I use emulators and my own phone to see if everything is working ok.  My apps are also writing data to shared preferences and a text file.

I can pull the data from my emulators through the `DDMS` in eclipse so I can read the data files on my computer, but when I try to open those folders through the `DDMS` on my phone, nothing happens.  I click the data folder and nothing happens.

My phone is rooted.  Is there any way I could pull the files from my phone?  I know that Android keeps these folders private, but there must be a way.  The emulator is just *way* too slow.

I have the javascript validation working good for my own code. I want to keep the validation. But when it comes to open source library, like jquery for example, the validation creates warnings.

**I don&#39;t want warnings over a downloaded library. But I want to keep warnings for my code.**

I know you can exclude files from validation in the &quot;*Preferences &gt; Validation*&quot; window, but **the javascript validation is not there** ! I&#39;ve looked each validator, the javascript validator is not there.

So how can I exclude specific files from the validation ?

Here is the list of validators I have :

How can I get the effect of choosing to import from both Maven and Git and have Eclipse properly generate my project? 

To get my project into Eclipse I can choose File-&gt;import-&gt;maven and then I get all the Maven projects imported and can build fine, or I can choose File-&gt;import-&gt;git and make a new project that ignores the pom.xml and does not generate the project properly. 

It seems I can do one or the other but not combine both so I get a correctly generated project.

The XML formatting works perfect but not the html formatting. In fact if I use &quot;cmd-shift-F&quot; for a html file, it just left aligns almost everything. I&#39;ve attached the before and after pictures.

Does anyone know how to fix this? I played around with HTML formatting preferences but had no luck. Note that the same document, if it is saved as xml will format perfectly.

I am using eclipse 3.6 with WTP plugin.

What are the most common and why not uncommon methods and tools used to do live debugging on the Linux kernel? I know that Linus for eg. is [against](http://lwn.net/2000/0914/a/lt-debugger.php3) this kind of debugging for the Linux Kernel or it least was and thus nothing much has been done in that sense in those years, but honestly a lot of time has passed since 2000 and i am interested if that mentality has changed regarding the Linux project and what current methods are used to do live debugging on the Linux kernel at the moment(either local or remote)?

References to walkthroughs and tutorials on mentioned techniques and tools are welcome.

I&#39;m using a lot of `qDebug() &lt;&lt;` statements for debug output. Is there any cross-platform way I can redirect that debug output to a file, without resorting to shell scripts? I&#39;m guessing that [open()][1] and [dup2()][2] will do the job in Linux, but will it work compiled with MinGW in Windows?

And maybe there is a Qt way to do it?
