I deploy the PetClinic Example of Spring framework-2.5.5 on JBoss 4.0.0.
During the deploy process i obtain the following error :
the absolute uri: ..... cannot be resolved in either web.xml or the jar files deployed with this application
at org.apache.jasper.compiler.DefaultErrorHandler.jsp Error(DefaultErrorHandler.java:39)

The web.xml uses the directive 2_4. I remember that the tld files are unnecessary.
Someone can have any ideas about this error?

Thanks
