Re: Struts-el and Weblogic 9.1
Weblogic has an option where you can force it load classes from the WEB-INF directory. I did that to eliminate any potential class loading conflicts... Still the same issue. I found a known issue http://edocs.bea.com/wls/docs91/issues/known_resolved.html#1056681 [CR210907] : Netui databinding expression language fails when BeanInfo overrides JavaBean property names. Evaluation of expressions in the Netui databinding expression language throws errors when BeanInfo netui databinding EL does not to work when java.beans.BeanInfo is used to override JavaBean property names. *Workaround or Solution*: Do not override JavaBean property names using BeanInfo if you use a JavaBean in Netui databinding. If you must databind to such a bean, wrap the bean in a UI version of the bean that follows the JavaBean property naming convention. Struts-el is essentially doing the same thing with mapping the property names using BeanInfo for each tag class. This is just a guess, at this point I am running out of idea... Servlet 2.4 is an option, just have a very large application that we will have to figure out how to port over... Thanks for all the comments/suggestions.

Re: Struts-el and Weblogic 9.1
When you say Weblogic is provdinig JSTL 1.1 version, you are reffering to standard.jar ? I don't have anything deployed except the example war. So I am not sure about the conflicts.

Re: Struts-el and Weblogic 9.1
9.1 used 2.4 and it is supposed to be backwards compatible. Just to make
things simple, I tried deploying the strutsel-exercise-taglib.war that
comes with the struts 1.2.8 release.
The tags don't work without any modifications to the war. If I modify
the web.xml in the war to be 2.4 compatible, it still doesn't work.
Here is the web.xml as modified to reflect 2.4 changes:
http://java.sun.com/xml/ns/j2ee";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee

If you need any more info, please let me know. I really want to find a
way to resolve this...

Are there any workarounds? I am using struts-el jar from the struts

Does anyone know which version of the Servlet spec Weblogic 8.1 and

My guess is that you've switched from Servlet 2.3 to 2.4, the same as
if you'd moved from Tomcat 4.x to 5.x. Hard to tell, though, without
more information.

Re: Struts-el and Weblogic 9.1
Weblogic 8.1 support servlet 2.3 and 9.1 should support servlet 2.4 Thanks, -Kalpesh - Yahoo! Mail Bring photos to life! New PhotoMail makes sharing a breeze.
