I am trying to load zk on websphere and get the following error.
3/9/06 14:01:34:247 CST] 4c92f59a WebGroup E SRVE0020E: [Servlet

Could not be defined due to: com/potix/zk/ui/http/DHtmlLayoutServlet (Unsupported major.minor version 48.0) This is often caused by having a class defined at multiple locations within the classloader hierarchy.

Thanks.

Where did you put zk.jar? According to the messages, it looks like zk.jar are found in multiple locations.

Hi! dcyaste,

I searched the Local ClassPath dumpped. I found at least two other jars should be there:

bsh.jar - The BeanShell script interpreter.

commons-el.jar - The EL script interpreter (Tomcat implementation. Maybe Websphere got its own implementation?).

I am not sure whether they are related to this symptom. However, the DHtmlLayoutServlet would refer to classes inside these two jars. These extra jars are located at following directory.

dist/lib/ext/*.jar.

If you are using Fckeditor or Dojo components (as in the zkdemo) you have to download related jars and copy to your WEB-INF/lib too.

Just to be sure, is there supposed to be a jar file named "commons-el.jar" in the dist/lib/ext/ directory. The one I found was bsh.jar and commons-fileupload.jar not commons-el.jar?

Thanks

EL is supported natively by Web server, so there is no need to distribute and install the file.

Tomcat uses commons-el.jar, but WebShpere might use another. I am not sure.

If WebShpere doesn't use commons-el, please let us know since you have to specify a proper class name in web.xml. Refer to Developer's Guide for details.

Websphere does not use commons-el.jar. What changes are needed for the web.xml?

Thanks.

You have to find out the class that implements javax.servlet.jsp.el.ExpressionEvaluator.

Then, specify it with init-param called el-evaluator-class. Refer to Appendix A for details.

Once you got ZK to work with WebSphere, please share it at http://en.wikibooks.org/wiki/ZK/How-Tos
Thanks.

What is the servlet and jvm level that ZK needs?

Sorry, I meant version. I am still not able to get ZK working with Websphere 5.x.

Thanks.
