Hi,
I am using GAE SDK 1.4.0 for developing my application. I want to
create a list with few null values in the middle. I am getting a
strange exception since afternoon. Here's the snippet of it ---
java.lang.UnsupportedOperationException
at java.util.AbstractList.add(AbstractList.java:131)
at java.util.AbstractList.add(AbstractList.java:91)
at com.example.web.util.paging.MyClass.setCursorForPage(MyClass.java:
275)
at com.example.web.util.paging.MyClass.updatePageCursors(MyClass.java:
267)
I have defined my list somehow like that :
List<Cursor> cursors = new ArrayList<Cursor>();
and the line where I get the exception is here -
Line 275: cursors.add(null);
My question is , why is the call leading to the AbstractList.java:131?
I am using ArrayList ( also tried with a vector) but the call ends up
in the AbstractList class which just throws the
UnsupportedOperationException - it does nothing else.
Similar code runs very well in Tomcat/Glassfish...whats different in
AppEngine??
Please help!
