Error reading web.xml with external entities when taglib is used
----------------------------------------------------------------
Key: JBAS-4005
URL: http://jira.jboss.com/jira/browse/JBAS-4005
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Web (Tomcat) service
Affects Versions: JBossAS-4.0.5.GA
Environment: MacOsX, JBossAS-4.0.5
Reporter: Angela Roberts
Assigned To: Remy Maucherat
See the sample application attached.
It contains a web.xml that uses an external entity:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app [ <!ENTITY inc SYSTEM "web-include.xml">]>
<web-app xmlns="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
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
&inc;
</web-app>
When the first JSP of this application is called, if this JSP declares a taglib, JBoss
can't find the included xml file.
This is the stack trace:
18:36:57,289 ERROR [MyEntityResolver] Invalid PUBLIC ID: null

The same application works ok on Tomcat 5.5.
I believe this is related to Bug http://issues.apache.org/bugzilla/show_bug.cgi?id=34034 .
This bug is already fixed on Tomcat, but the way class
org.jboss.web.tomcat.tc5.jasper.TagLibCache deals with entities may be the problem.
