I could run the "HelloWorld1" Qt-Jambi application with GUI as standalone.
I could run the "HelloWorld2" teamcenter-plugin (via Eclipse) inherited ViewPart.
Trying to init QApplication within plugin like below:
public class MyComView extends ViewPart
{
static
{
//try to init Qt-Jambi
//
System.out.println("QQ==before load qtjambi");
//
QApplication qap1 = QApplication.instance();
//
System.out.println("QQ==after get instance");
}
//...
}
My code is quite good compiled and linked.
But I have a java.lang.ClassNotFoundException error with below stacktrace:

What did I do wrong? How do I properly use Qt-Jambi within Eclipse-RCP, especially within a Teamcenter plugin?
java.lang.NoClassDefFoundError can be thrown for several reasons. The code compiles nicely, but throws that exception during runtime.
If you run it from the command-line within a .jar file, then it could be that it not listed in the manifest of the jar file.
If you run it with in Eclipse, check your classpaths, or make sure the class can be found in working directory.
com/trolltech/qt/gui/QApplication depends on native libary code, so make sure you have the Qt Jambi native libs with your classpath or working directory.

I wrote a program in java and now I want to run it using groovy. I did this as an exercise, so don't question why I haven't programmed in groovy in the first place. ;)
I used many libraries in java, so I copied them to the %GROOVY_HOME%\lib directory. After I did this, I wasn't able to run groovyConsole.exe anymore, so ran groovyConsole.bat (using cmd) to get the error, which is following:

The libs I used worked fine in eclipse using java. What can I do?
Additional question:
I found a way to use libraries by loading files. Is there a way to load intire directories with jar files?
this.getClass().classLoader.rootLoader.addURL(new File("file.jar").toURL())
You should not add your script dependencies to %GROOVY_HOME%/lib.
You should instead change your script to declare the dependencies it needs.
One way is to do as you found with the adding JAR URLs to a class loader. If you want to add a directory, list the directory and iterate over the JAR files, something like new File('path/to/dir').eachFileMatch('*.jar') { ...addURL(it.toURI().toURL()) }.
Btw. as you can see in my example, you should never use File.toURL(), this is deprecated since a long time. Always do File.toURI().toURL() instead.
Besides all this, there is a better way to depend on libraries in Groovy scripts, which is Grape. You can read more about it at http://groovy-lang.org/grape.html. Basically you just declare your dependencies with annotations and they are automatically downloaded from a Maven repository and added to the classpath of your script, including any transitive dependencies.

the reason for this error is the jar file which contains the class for wsgen task is not included in your classpath.
If you are using jdk1.6 check your eclipse environment that you are using jdk1.6 not the jre.
because in java 1.6 you can find wsgen task under JAVA_HOME/bin.
if you are using other version of java try searching for the relevant jar under your application server lib folder.
Please note: to check if you eclipse is using jdk or jre go to windows->preferences->java->Installed JREs and select the jdk instead of jre.
Thanks to rbhawsar. You were spot on.
I needed to set the environment variables first.
i.e:
Path : C:\Program Files (x86)\Java\jdk1.6.0_35\bin
JAVA_HOME: C:\Program Files (x86)\Java\jdk1.6.0_35
I have followed This Link as have been over 6 years since last touched JAVA. So now back to business :)

I'm currently using java 1.6.0_32, Tomcat 7.0.27 and Eclipse Europa.
How could I solve this error?
May be your Eclipse installation has a problem. Try to re-install WTP or get new eclipse.
I had the similar problem.I am using the eclipse-Kepler-sr2-javaEE.
The Issues was in Tomcat-7 server. I deleted the server from project-explorer and also from Windows->preferences->server->Runtime Environment.
Finally I am able to create the Servlet.
I am developing a plug-in in Eclipse RCP and I have to read and write in some ini files. For that I am trying to use the ini4j library which I downloaded and added the jars as external jars in the Build Path for the project.
But when I launch the project and try to read the files I get this error:

I googled for a solution and apparently I should also update the classpath of the project for it to work. But I am launching my project as an Eclipse Application and there is no Classpath tab when I go into the Run Configurations window.
What can I do for it to work?
Your plugin.xml editor has a Runtime-Tab - there you will find a possibility to add entries to your plugin-classpath.
Add the jar and you should be set to go..
I am trying to deploy Sonar (automatic code monitoring tool) on a Jetty 7 servlet container.
I would like to use the default config first (embedded Derby DB) as a POC and transition to a production grade DB later.
So far I have tried various ways to make this work (todo: document failed attempts) without any luck...
Did anyone managed to pull this off?
This is the exception I get by deploying in jetty/webapps and launching with
java -DOPTIONS=Server,deploy,jsp -jar start.jar etc/jetty.xml

Sonar tries to bind its JDBC datasource to JNDI. But it seems that Jetty 7 needs some extra-configuration to allow this. See this thread for more details.
I hope it helps.
