Hello,
I have managed it to add my own bean to the pallete. I can click on my
bean and I can place it on a frame. The only thing is I have to add
"MyJButton.jar" to the classpath (on the wizard "Properties"). Otherwise I
get an exception
------------------------------------------------------------ ----------------
java.lang.ExceptionInInitializerError: IWAV0118E Class IWAV0189E unknown
(or one of its superclasses) is not found or has errors.
at
org.eclipse.ve.internal.java.core.BasicAllocationProcesser.i nstantiateWithString(BasicAllocationProcesser.java:203)
at
org.eclipse.ve.internal.java.core.BeanProxyAdapter.basicInit ializationStringAllocation(BeanProxyAdapter.java:903)
...
------------------------------------------------------------ ----------------
There is
********************************************
<runtime>
<library name="MyJButton.jar">
<export name="*"/>
</library>
</runtime>
********************************************
in the "plugin.xml". I have read that this entry adds libraries to the
class path. Is it not enough?
Thank you in advance
Elena

Hi Elena,
The MyButton.jar in the plugin.xml is for Eclipse to know where your
classes are and use them. However the project that you have in your
workspace is on a completely different classpath than the Eclipse which
is handling that project. If you need MyButton.jar classes in the
project also, you would need to add it to the classpath manually - or
provide some action (menu, etc.) to add that JAR automatically to the
classpath.
It is like having the SWT JARs - Just because Eclipse has the JARs in
its classpath, doesnt mean the applications in a new Java project get
them too. The applications in your project ultimately run on a
completely different VM - and that VM would need to know which JARs are
needed via the classpath. Hope ive made sense.
Regards,
Sri.
