Try this

    java -jar &lt;jar-file-name&gt;.jar

If you dont have an entry point defined in your manifest invoking `java -jar foo.jar` will not work.

Use this command if you dont have a manifest or to run a different main class than the one specified in the manifest:

    java -cp foo.jar full.package.name.ClassName

See also instructions on how to create a manifest with an entry point:
https://docs.oracle.com/javase/tutorial/deployment/jar/appman.html



`java [any other JVM options you need to give it] -jar foo.jar`

You can run a JAR file from the command line like this:

    java -jar myJARFile.jar

Is there any reliable way to get a `Context` from a `Service`?

I want to register a broadcast receiver for `ACTION_PHONE_STATE_CHANGED` but I don&#39;t need my app to always get this information, so I don&#39;t put it in the `Manifest`. 

However, I can&#39;t have the broadcast receiver be killed by the GC when I need this information so I&#39;m registering the broadcast receiver in a `Service`. 

Hence, I need a `Context` to to call `registerReceiver()`.
 When I no longer need the `ACTION_PHONE_STATE_CHANGED` I **unregister** it.

Any tips?

I am on the stage of development, where I have two modules and from one I got output as a `OutputStream` and second one, which accepts only `InputStream`. Do you know how to convert `OutputStream` to `InputStream` (not vice versa, I mean really this way) that I will be able to connect these two parts?

Thanks

Is there a way I can configure maven to *always* download sources and javadocs? Specifying `-DdownloadSources=true -DdownloadJavadocs=true` everytime (which usually goes along with running mvn compile twice because I forgot the first time) becomes rather tedious.

I am using Java Properties to read a properties file. Everything is working fine, but Properties silently drops the backslashes.

(i.e.)

    original: c:\sdjf\slkdfj.jpg

    after: c:sdjfslkdfj.jpg

How do I make Properties not do this?

I am using the code `prop.getProperty(key)`

Somehow I manage to create new rows between two rows in an existing excel file. The problem is, some of the formatting were not include along the shifting of the rows. 

One of this, is the row that are hide are not relatively go along during the shift. What I mean is(ex.), rows from 20 to 30 is hidden, but when a create new rows the formating still there. The hidden rows must also move during the insertion/creation of new rows, it should be 21 to 31. 

Another thing is, the other object in the sheet that are not in the cell. Like the text box are not move along after the new row is created. Its like the position of these object are fixed. But I want it to move, the same thing as I insert a new row or paste row in excel. If there is a function of inserting a new row, please let me know.

This what I have right now, just a snippet from my code.

    HSSFWorkbook wb = new HSSFWorkbook(template); //template is the source of file
    HSSFSheet sheet = wb.getSheet(&quot;SAMPLE&quot;);
    HSSFRow newRow;
    HSSFCell cellData;

    int createNewRowAt = 9; //Add the new row between row 9 and 10
    
    sheet.shiftRows(createNewRowAt, sheet.getLastRowNum(), 1, true, false);
    newRow = sheet.createRow(createNewRowAt);
    newRow = sheet.getRow(createNewRowAt);

If copy and paste of rows is possible that would be big help. But I already ask it here and can&#39;t find a solution. So I decided to create a row as an interim solution. I&#39;m done with it but having a problem like this. 

Any help will be much appreciated. Thanks!

I have an array `a` which is constantly being updated. Let&#39;s say `a = [1,2,3,4,5]`. I need to make an exact duplicate copy of `a` and call it `b`. If `a` were to change to `[6,7,8,9,10]`, `b` should still be `[1,2,3,4,5]`. What is the best way to do this? I tried a `for` loop like:

    for(int i=0; i&lt;5; i++) {
        b[i]=a[i];
    }

but that doesn&#39;t seem to work correctly. Please don&#39;t use advanced terms like deep copy, etc., because I do not know what that means.

I am currently working on a J2ME polish application, just enhancing it. I am finding difficulties to get the exact version of the jar file.
Is there any way to find the version of the jar file for the imports done in the class? I mean if you have some thing, import x.y.z; can we know the version of the jar x.y package belongs to?

What is the difference between a `.jar` and a `.war` file?  
Is it only the file extension or is there something more?

I know this may be a silly question for experienced coders. But I have a library (an http client) that some of the other frameworks/jars used in my project require. But all of them require different major versions like:

    httpclient-v1.jar =&gt; Required by cralwer.jar
    httpclient-v2.jar =&gt; Required by restapi.jar
    httpclient-v3.jar =&gt; required by foobar.jar

Is the classloader intelligent enough to seperate them somehow? Most likely not? How does the Classloader handle this, in case a Class is the same in all three jars. Which one is loaded and why? 

Does the Classloader only pickup exactly one jar or does it mix classes arbitrarily? So for example if a class is loaded from Version-1.jar, all other classes loaded from the same classloader will all go into the same jar? 

How do you handle this problem?

Is there some trick to somehow &quot;incorporate&quot; the jars into the &quot;required.jar&quot; so that the are seen as &quot;one unit/package&quot; by the `Classloader`, or somehow linked?

I have a nasty problem referencing resources when using a Maven project and Jar files...

I have all my resources in a dedicated folder /src/main/resources which is part of the build path in Eclipse. Files are referenced using 
&lt;pre&gt;&lt;code&gt;getClass().getResource(&quot;/filename.txt&quot;)
&lt;/code&gt;&lt;/pre&gt;

This works fine in Eclipse but fails in the Jar file - there the resources are located in a folder directly below the jar&#39;s root...

Does anyone know a &#39;best practice&#39; to reference a file both in the JAR and (!) in Eclipse?

&lt;b&gt;Edit:&lt;/b&gt;
The problem is that while the resources actually are located in the JAR in a folder &quot;resources&quot; at the top level, the above method fails to find the file...

What is the difference between the maven scope `compile` and `provided` when artifact is built as a JAR? If it was WAR, I&#39;d understand - the artifact would be included or not in WEB-INF/lib. But in case of a JAR it doesn&#39;t matter - dependencies aren&#39;t included. They have to be on classpath when their scope is `compile` or `provided`. I know that `provided` dependencies aren&#39;t transitive - but is it only one difference?
