[pde-dev] Editing an Imported Eclipse plugin

[nikunj badjatya <nikunjbadjatya@xxxxxxxxx>]

Hi All,
I am completely new to Eclipse world. 

I have few doubts -

Q1. If I import any plugin ( ex. helloworld plugin, as a jar ) How can I
 edit it in the eclipse environment.? 
I have initially exported the helloworld plugin with its source jar. 
Now when I import it back, I can see the .java files. but I am not able 
to edit those.??


Q2. I would like to know what all plugins available in bare eclipse. 
That is , Without any JDT or PDT etc installed.??


Q3. If I want to have my eclipse edition, which contains only helloworld
 plugin within its library. That is, Only helloworld menubar/menuitem 
and toolbar button. Is this possible??


Kindly Help..!!

Thanks,
