Subject [jira] [Commented] (WW-4223) <s:debug/> tag throws NPE when used with Jetty
Date Mon, 21 Oct 2013 08:36:43 GMT

    [ https://issues.apache.org/jira/browse/WW-4223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13800465#comment-13800465
] 

Yasser Zamani commented on WW-4223:
-----------------------------------

I discovered the source of the problem. It seems that there is no problem with Struts itself
but when you run a Struts application on:
* *Jetty:* _TagLibraryInfoImpl_ class will be resolved from _jetty home/lib/jsp/org.apache.jasper.glassfish-2.2.2.v201112011158.jar_
where line #129 is:
{code:title=TagLibraryInfoImpl.java:129|borderStyle=solid}
print("tagLibraryValidator", tagLibraryValidator.toString(), out);
{code}
*but in*
* *Tomcat:*  _TagLibraryInfoImpl_ class will be resolved from _tomcat home/lib/jasper.jar_
where equivalent code at line #94 is:
{code:title=TagLibraryInfoImpl.java:94|borderStyle=solid}
print("tagLibraryValidator", "" + tagLibraryValidator, out);
{code}

These facts show that when _tagLibraryValidator_ is null, Jetty will be broken by NPE (because
of _tagLibraryValidator.toString()_) but Tomcat continues well (because of _"" + tagLibraryValidator_).
:)
