[gef-dev] Problem while exporting a Plugin and then adding it to eclipse

["narayan pawar" <narayan.pawar@xxxxxxxxx>]

Hi friends

I am Narayan.

My project configuration includes extension to the

              1. org.eclipse.ui.actionSets    ----  to launch application from Main Menu bar

              2. org.eclipse.ui.newWizards  ----   to take input files from User

              3. org.eclipse.ui.views            ----  to present processed info

              4. org.eclipse.ui.editors          ----  to present processed info

 

With this my project runs correctly.

 

Now I am exporting this application as "Deployable Plugins and Fragments" and adding it to the Plugin folder of Eclipse installation.

 

After this i can see my Menu item into the Menu bar

However once i click on MenuItem, it is not showing the Wizard page and generating following error.....

As shown above It is showing some exception related with : --- "java.lang.NoClassDefFoundError: org/eclipse/core/resources/IContainer"

I am not able to understand and find out any solution.

My Configuarion includes:

--- Eclipse3.3

--- Jdk1.4

 

If anyone can help me, it will be really useful. i am looking forward to receive response about Solution or any workaround.

Also if anyone knows about some Documents,Examples,samples related with Eclipse Plugin Export "Deployable Plugins and Fragments".please let me know.

 

Thanks in advance
