Carlos Oliveira updated JBWEB-244:
----------------------------------

    Attachment: test.war


For testing, deploy and call http://localhost:8080/test/index.jsp on browser. It shows the jboss-web.xml version instead of the web.xml version

> I'm migrating an old application from jBoss 4.0.5 to 6.1.0. 
> This application has some some TLDs who does not accept return expression on some attributes, but unfortunately the JSPs use expressions on these attributes. This is working fine since the servlet version 2.3 and below accept this.
> The problem is that jBoss 6.1.0 isn't accepting this, it returns an error saying the attribute does not accept return expressions. My web.xml it's especifying version 2.3. 
> I checked out the jboss web 3.0.0 code and verified that the class org.apache.jasper.compiler.JspConfig is responsible to check the servlet version (line 99), setting defaultIsELIgnored to true and thus allowing expressions.
> But this is not working correctly if the war has a jboss-web.xml especifying a DTD, like this example.
> <?xml version="1.0" encoding="UTF-8"?>
> <!DOCTYPE jboss-web PUBLIC "-//JBoss//DTD Web Application 2.3V2//EN" "http://www.jboss.org/j2ee/dtd/jboss-web_3_2.dtd">
> <jboss-web>
> 	<context-root>/test</context-root>
> </jboss-web>
> Jboss WEB is reading the DTD file from jboss-web.xml and replacing the SERVLET_VERSION on org.apache.catalina.core.StandardContext line 4383
> It works fine if i remove the DTD line from jboss-web.xml
> I attached an example, deploy the war file and call on browser the url http://localhost:8080/test/index.jsp, it shows the version from jboss-web.xml instead of the web.xml
> For now, as an workaround i created a Tomcat valve forcing the version
>             request.getContext().getServletContext().setAttribute("org.apache.catalina.SERVLET_VERSION", "2.3");
