Hi Brain,
Thanks a lot for your solution… the plug-in
worked fine after the change in the Bundle-Classpath.
Once again thanks a lot for your timely help!!!!
Thanks & Regards,
Sriram

I think we have a solution. In the Manifest, you
need to add "." to your Bundle-Classpath.
Bundle-ClassPath:
lib/ant-23.jar,
lib/commons-beanutils.jar,
lib/commons-collections.jar,
lib/commons-lang.jar,
lib/commons-logging.jar,
lib/commons-validator.jar,
lib/xercesImpl.jar,
.
Here is the reason. in your build.properties, "source." is the
prefix used to designated the library for which a source folder represents. By
default (which is also you situation), this library will be ".". The
runtime will search the entries on the Bundle-Classpath to load classes. Since
"." is not on the Bundle-Classpath, the runtime will never find the
library which contains the code from your source folder. Let me know if
adding "." solves the problem.

RE: [pde-dev] Plug-in was unable to

Hi Brian,
Thanks a lot for your quick response.
The referred class is from the source folder. In my eclipse
project, the file is under the package hierarchy <<project-name>> /
src / jcv / action.
Inside the plug-in jar the corresponding java file
“DefinePqmMenuAction” is packaged under “jcv\action”
The jar tree is –
JavaCodeValidator_1.0.0.jar
jcv
action
activator ….
lib
<< all external jars >>
meta-inf
manifest.mf
plugin.xml
The build properties file is below-
source..
= src/
output..
= bin/
bin.includes
= plugin.xml,\
META-INF/,\
.,\
icons/,\
html/,\
*.xml,\
lib/ant-23.jar,\
lib/commons-beanutils.jar,\
lib/commons-collections.jar,\
lib/commons-lang.jar,\
lib/commons-logging.jar,\
lib/commons-validator.jar,\
lib/xercesImpl.jar
Please guide me accordingly.
Thanks & Regards,
Sriram

Hi Sriram,
Welcome to PDE :) You are right, this is a common problem so lets see
what we can do to help.
I take it this class is in a source folder in your project. If not, where
is this class suppose to be coming from (which jar)? If so, could you
send your build.properties file. One of the most common errors,
especially when it does not run after export, is that the bundle is not be
assembled properly. The build.properties is responsible for this and
therefore is a good place to start if your class is suppose to come from a
source folder.

[pde-dev] Plug-in was unable to load class
jcv.action.DefinePqmMenuAction.

Hi All,
I am new to eclipse plug-in development. I have created a plug-in and tested
the same using the “Launch an Eclipse application”. It is working
fine in this case.
I then created a plug-in jar using the “Export-Wizard” and placed
the jar into the plug-in directory. However when I launch eclipse and try to
access the preferences page; I get the error as “Could not create action
delegate for id: jcv.action.DefinePqmMenuAction”. This is due to a
ClassNotFoundException.
I guess this problem has been encountered before. I am currently stuck up with
this issue and am unable to proceed. Kindly guide me.
Provided below is the log details-
eclipse.buildId=M20060628-1325
