Upgrade CR1 to CR2

[pingus]

After an update of Seam CR1 to CR2 I'll get an java.lang.ClassFormatError.

2007-10-10 11:43:42,091 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/joe]] Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener
java.lang.ClassFormatError: Illegal class modifiers in class org/jboss/seam/remoting/package-info: 0x1600

I'm using JBoss AS 4.2.1 and Java 1.5.0_12 (64bit).

Any idea whats going wrong here?

You could try downloading Seam again, as it sounds like the jar is corrupt.

The download was OK, but your hint was helpful anyway :-)

I've checked all libraries in lib and found a differences for all the jboss-seam jars. After that I realized, that I've invoked ant build to solve the issue with seam-gen and missing dependencies.

I've replaced all jboss-seam jars with the files from the original download and it works.

Thanks

I have the same issue here and can't solve it. Could you please be more specific:
- Which lib directories did you have compared?
- And in which place did you replace all jboss-seam jars?
- Where did you take the original jars from (from jboss-seam-2.0.0.CR2.zip) ?

Ok, i found the solution. It was a little bit tricky because i used a development pc without network connection and had to excange data on an usb stick.

1. download jboss-seam-2.0.0.CR2.zip and extract it
2. open a command prompt and change to the jboss-seam-2.0.0.CR2 directory
3. type "ant build"
4. type "seam setup" and answer all the questions
5. replace the directory jboss-seam-2.0.0.CR2/lib with the lib directory from jboss-seam-2.0.0.CR2.zip
6. type "seam create-project" to create a empty seam web application

(The directories ant/bin and java/bin have to be in the PATH)
