Hi Sudhir,
I finally managed to solve this (at least ir worked for me). Just edit
the ".classpath" file in your eclipse project and review the order of
this two entries:
<classpathentry kind="con"
path="com.google.appengine.eclipse.core.GAE_CONTAINER"/>
<classpathentry kind="con"
path="com.google.gwt.eclipse.core.GWT_CONTAINER"/>
I had GWT_CONTAINER before GAE_CONTAINER, after reordering it started
compiling JSPs again.
Hope this helps,
Eduardo.
