JSBuilder2 needs a .jsb2 file which describes the files to process. The ext.jsb2 to build the Ext JS library is included in the Ext JS SDK.
The only exception is Ext 3.0.0 SDK. You can download the ext.jsb2 file for Ext 3.0.0 here.
Thankyou for the reply condor, now this is very clear that the output i get is a single .js file and a single .css file, and JSBuilder2 would pick up the (source .js files) and (source .css files) i need from the .jsb2 filei create.
and after creation of .jsb2 file i use JSBuilder2.jar to get a single .js and single .css file and then i shall include those generated .js and .css in my html.
I m a newbie user of extjs could you tell me How to create that jsb2 file of my own compilation?
