Failure to evaluate Ternary operators in EL : JBoss 5.0.0-Be

[saasira]

Hi!
I'm getting the following error when my page contains Ternary operators in EL :

We are migrating our code from WAS 6.1 to JBoss.

The same el expression is working fine in Tomcat 6.0.14 or WebSphere 6.1.

Can some one explain why the tomcat el processor is not able to parse that expression, when it does if it is not in JBoss!
Has Jboss done any changes to the Tomcat engine which is causing this failure?
Or may be am i missing some thing that needs to be done for Jboss?
awaiting your answer,

Thanking you in advance,
Samba

Hi

I am also facing same issue. Please let me know did you got the solution for this.

We are migrating an application from WAS to JBoss EAP 5.0.

The same el expression is working fine in Tomcat 5.0. or WebSphere 7.0.

The error is:

Caused by: org.apache.jasper.JasperException: An exception occurred processing JSP page /jsp/xxx.jsp at line 27

[jfclere]

I think it is JBWEB-144

[chsrikanth807]

I did not understand. What configuration settings i need to change to resolve this issue.

[jfclere]

It is not a configuration issue. It is a bug either in your application or in the EL of jbossweb.

BTW: You are using EAP so probably you have a subscription for support, use it.
