Subject RE: XInclude in faces-config file
Date Thu, 22 Sep 2005 18:38:18 GMT
Thanks for the reply. At the risk of sounding obtuse, where exactly is the
correct place to define this property? I tried to look for it in the Tomcat
docs but couldn't find anywhere that talks about this. I tried setting it as
a -D at tomcat startup, which doesn't seem like the correct place to set
this, and it didn't work anyway. Do I put this in the web.xml of the web
application as a context parameter?

Subject: XInclude in faces-config file


I'm attempting to modularize one of the xml files by using XInclude under
Tomcat 5.5.9. The application starts, but at the point in time when the
beans should get instantiated I get a NullPointerException in the
ManagedBeanFactory. In the example below, I'm trying to include file2.xml in
file1.xml, but it appears that the include directive is being ignored. Note
that if I insert the contents of file2.xml directly into file1.xml,
everything works as expected. Can anyone offer any insight in what I'm doing
wrong?

file1.xml
----------
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer
Faces Config 1.0//EN" 
"http://java.sun.com/dtd/web-facesconfig_1_0.dtd">

<faces-config xmlns:xi="http://www.w3.org/2001/XInclude" >
  <managed-bean>
     <managed-bean-name>bean1</managed-bean-name>
      ...
  </managed-bean>
  ...
  <xi:include href="file2.xml"/>
</faces-config>


file2.xml
-----------
  <managed-bean>
     <managed-bean-name>bean2</managed-bean-name>
      ...
  </managed-bean>
