| [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 java.version=1.4.2_03 java.vendor=Sun Microsystems Inc.
