[news.eclipse.newcomer] java.lang.NullPointerException when running debuging

rchiles@xxxxxxx (Richard Chiles) — Fri, 18 Sep 2009 15:53:44 GMT

The debugger is throwing a java.lang.NullPointer.Exception when starting the debug session.

I have created a simple HelloWorld app. I am running Cygwin on Windows.

Below is the output from the console window. It appears gdb is exiting prematurely.

As a check, I ran gdb on the application outside of Eclipse and had not problems.

Console Window Output 29-gdb-set confirm off 29^done (gdb) 30-gdb-set width 0 30^done (gdb) 31-gdb-set height 0 31^done (gdb) 32-interpreter-exec console echo 32^done (gdb) 33-gdb-show prompt 33^done,value="(gdb) " (gdb) 34-gdb-set auto-solib-add on 34^done (gdb) 35-gdb-set stop-on-solib-events 0 35^done (gdb) 36-gdb-set stop-on-solib-events 1 36^done (gdb) 37-gdb-set new-console on 37^done (gdb) 38-environment-cd C:\workspace\HelloWorld 38^done (gdb) 39-environment-directory C:/workspace/HelloWorld 39^done,source-path="C:/workspace/HelloWorld:$cdir:$cwd" (gdb) 40 info threads &"info threads\n" &"No registers.\n" 40^error,msg="No registers." 41-data-list-register-names (gdb) 41^done,register-names=["eax","ecx","edx","ebx","esp ","ebp","esi","edi","eip","eflags","cs","ss","ds ","es","fs","gs","st0","st1","st2","st3","st4 ","st5","st6","st7","fctrl","fstat","ftag","fiseg ","fioff","foseg","fooff","fop","xmm0","xmm1","xmm2 ","xmm3","xmm4","xmm5","xmm6","xmm7","mxcsr","mm0 ","mm1","mm2","mm3","mm4","mm5","mm6","mm7"] (gdb)

Thanks Eric!

You're right, it's not an Eclipse problem.

I fixed it by setting the target attribute in javac.

Thanks for the timely response.

How do I switch back to Java 1.5?

I don't see how this is related to Eclipse. Even so, I can provide some answer: do you know about the Java Preferences app (it should be in your Utilities folder)? That is where you set the system preference for which JDK is used by default. I suppose you could also try specifying it in the Ant javac task, although I don't remember exactly how to do that off the top of my head; I'm sure the Ant documentation has instructions.

Well, unfortunately you are right :-(

You might want to file a feature request at bugs.eclipse.org/bugs

Two possible solutions come to my mind:
- Static code analysis (write your own checkstyle or pmd check)
- Use a code coverage tool like eclemma (www.eclemma.org). Besides
  showing you whether all methods are called, it tells you which lines
  of code are uncovered by the test which is IMHO a more accurate and
  more useful information for the developer.

Hello

Besides the (LEFT|RIGHT|BOTTOM|TOP) you can make views relative to each
other using the 'relative' attribute of the perspective extension point.

See:

Hello

> i tried settting team->set property->svn-ignore. 
The property is correctly called 'svn:ignore' and the property value
should be set to '*'. After setting the property you have to commit this
property change on the directory to the svn repository as svn does not
know such a thing like local properties.

(Alternatively, you might try to set 'svn:ignore' with the property
value 'dir-to-ignore-name' on the parent directory.)

[news.eclipse.newcomer] new PHP project creation error in PDT

neothinkx@xxxxxxx (Raman) — Fri, 18 Sep 2009 00:01:26 GMT

Hi

i recently made a switch to eclipse PDT from Aptana. but i am unable to create a new php project successfully. when i start with general new project i have no issues but when i start with new php project wizard and after typing new project's name i click next, next and then finish i get error message that "creation of element failed Reason Build path contains duplicate entry. "

now if i go back and remove php language library from libraries, my project get created successfully.

why it is happening like that.

how and where i can edit preferences to prevent not including php language library twice.

thanks

[news.eclipse.newcomer] Sounds in Server Audio don't appear to work

davidmichaelkarr@xxxxxxx (David M . Karr) — Thu, 17 Sep 2009 22:48:17 GMT

Eclipse 3.5.

If I go to "Server"->"Audio", then select either the "Server Started" or "Server Stopped" lines, checking the checkbox and then setting the "Audio File" to a path to an existing WAV file, will Eclipse play that sound file when the process of stopping or starting a server is completed?

It doesn't appear to do anything for me.  I've set the volume as high as it will go, and I've used sound files that I know make a sound when I play them manually.
