ClassCastException in OpenSessionInViewFilter

[fabio.patricio]

Hi,

When beginning tomcat an error of ClassCastException occurs. Somebody knows what it can be?

I'am using Spring 1.2.1 with Hibernate 3.0.5 in tomcat 5.5.x and JDK 5.0


SEVERE: Exception starting filter hibernateFilter

Best Regards,

Do you have multiple versions of the Spring JAR file on the classpath?

I am getting the same error. Is there a solution. I have spring 2.0.2.

[karldmoore]

Have you tried what Rob said and checked the classpath for multiple Spring jars? Is it possible to see your web.xml?

[Kruttik]

ya i checked the classpath. heres the web xml:

I get this using jboss 4.2.1 does anyone know how to resolve this?

Thanks

Have you checked for a second servlet.jar or j2ee.jar or something like it in your classpath? Looks like you have two classes java.servlet.Filter on your classpath.
