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-
