NoClassDefFoundError when creating PageableTable in RAP appliction [message #1077556]

Hi ,
I am trying to create Pageable Table in eclipse RAP application in web form.
My application doesn't seem to find "TableTreeItem" class. I get following error:

java.lang.NoClassDefFoundError: org/eclipse/swt/custom/TableTreeItem

Code:

PageableTable paginationTable = new PageableTable(shell, SWT.BORDER);

Now I am referring org.eclipse.rap.rwt/2.1.0/org.eclipse.rap.rwt-2.1.0.jar which should contain this swt class.

What can be the reason? Doesn't RAP support Pageable Table in web form of RAP?

Hi Rohit,

I don't understand the link between "TableTreeItem" and "PageableTable".
"PageableTable" doesn't use "TableTreeItem", so your problem should come from other reasons.

if you read javadoc of TableTreeItem (RCP), this class is deprecated since 3.1. Perhaps Eclipse RAP has removed this class (to check).

Regards Angelo

Hi Angelo,
Thank you for your reply.
I searched more after your answer and it helped me
to solve this problem but I don't know whether I have proper answer.
I created one sample hello world RAP application and added PageableTable and it worked perfectly but for my application it was not working. I was using maven dependencies and referring jars org.eclipse.rap.rwt of version 2.1.0 and jface of version 3.3.0-I20070606-0010 which are the latest in maven repository. However in Sample RAP application I see following jars which I added in my application and it worked perfectly:

org.eclipse.rap.rwt : 2.1.0.20130611-2139
org.eclipse.jface: 2.1.0.20130506-1748
