NullPointerException when running snippets

Jared Russell (1.3k●1●20●19) | asked Mar 07 '11, 12:59 p.m.
Hi,

I'm trying to setup my development environment for RTC 3 and I'm having an issue when trying to run the plainjava snippets. I've been following the guide here.

I have the RTC 3 client installed to: C:\rtc\jazz - 3.0, with the plainjava libraries installed to C:\rtc\jazz - 3.0\client\plainjava.

I then created a new plugin project as per the guide referenced above, using the plainjava fodler as the location. I then added all of the dependencies in the Automated Management of Dependencies section, saved the project, added the dependencies to the Required Dependencies section, and finally deleted all dependencies from the automated section. At this point the snippets all compile with no errors.

To try and run snippet 1, I created a debug configuration with the Snippets project and snippets.Snippet1 main class selected. In the arguments tab I entered the following VM argument: -Djava.ext.dirs="C:\rtc\jazz - 3.0\client\eclipse\jdk\jre\lib\ext":snippets:.. In the classpath tab I select the User Entries section and then select Add JARS's... and select all JAR's in the snippets folder.

When I run this configuration I get the following output from the eclipse console:

Does anyone have any ideas why I'm seeing this?

I have found that if I remove the JVM argument from the debug configuration the exception is no longer thrown, and the snippet runs ok, however I still see the "SEVERE" entries in the log file...

Just wanted to add something important. This solution worked for me, but as having the workspace on linux, the environment variables should be separated by ":", not ";". Example: -Djava.ext.dirs=path-to-env\jazz\client\plainjava:snippets:path-to-env\jazz\server\jre\lib\ext:. snippets.Snippet1

Hello,

I just found the same problem, and I fixed it as indicated in https://jazz.net/forums/viewtopic.php?p=26680

To fix it using your command line (on windows environment), you can include the ext/lib of the server as following
java -Djava.ext.dirs=path-to-env\jazz\client\plainjava;snippets;path-to-env\jazz\server\jre\lib\ext;. snippets.Snippet1

Hope this help !

In some post i read that this issue is related to enviornment or class path setting but not really sure what the exact cause is.

I checked at my end but the settings looks OK :| . Also, at my end, this dont interfere with proper functioning of code.

Achal

I'm seeing the same issue. Was anybody able to resolve this problem?

I also got similar errors(pasted below) under similar circumstances. Any idea why this is happening and what could be the solution for it?

Hi,

I've found the same messages for RTC 2.0 (no NullPointerException but received the same ExtensionRegistryReader errors.
