[jboss-jira] [JBoss JIRA] (WFLY-12701) JSTL EL Evulation not working properly throwing NoClassDefFoundError

[James Perkins (Jira)]

    [ https://issues.jboss.org/browse/WFLY-12701?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13804661#comment-13804661 ] 

James Perkins commented on WFLY-12701:
--------------------------------------

I cannot reproduce this. Given the instructions and the stack trace though it seems like there are some mismatches in the deployment itself.

{quote}
2. create a bean object com.akash.Person and add
<jsp:useBean id="person" class="com.akashPerson" scope="session"/>
{quote}

Maybe just a type, but the above references a bean called {{com.akash.Person}}, but the JSP class is set to {{com.akashPerson}} note the missing {{.}} (dot). Maybe this is just a type though.

In the stack trace it references {{com/akash/web/beans/deviceBean}} which is in the instructions. Maybe this is the real stack trace vs the instructions to reproduce. 

I'm closing this as Cannot Reproduce. If you feel this is still an issue it would be helpful  to add a simple reproducer as I could not reproduce this.
