Hi My struts version is 2.0.6 and tiles is 2.0 and I don have any other errors. Differences between locan and remote also I couldnt see – veeru 9 mins ago

Got the answer . Problem solved. The mistake wa in web.xml .

The local server is on windows where as remote server is on unix so there is a mistake in mentioning the relating path in web.xml ( / not required in unix server)

This may be caused by missing dependencies. Doing a search for this error turns up several occurences of people not including:

• commons-beanutils-VERSION.jar
• commons-collections-VERSION.jar
• commons-digest-VERSION.jar

Make sure you have all the requirements listed here: To use Tiles in your application you need

Here is another example of the same error: Struts2 & Tiles: When apache.org is down my webapp fails to start

The last one is a DTD version mismatch.

As you can see it can be due to several reasons, but since it works on your local PC and not the remote, I would lean towards missing dependencies.
