We packaged two web applications in a J2EE application.



We found that when we access a web application, JBoss load the classes in another web 
application's WEB-INF/lib or WEB-INF/classes.(the incorrectly loaded classes is not 
place in the jar files in EJB container or JBoss's default lib or CLASSPATH).



THis occurs in JBoss 3.2.3, but never occures in JBoss 3.0.8-Tomcat-4.1.24.



The following is the description.

     (1)the build script has problem, it copy an older version jar file to the 
WEB-INFO/lib, this jar file is used by web application to parse the XML file that 
define the screen layout. We found that the XML file cannot be parsed when we port our 
J2EE application to JBoss 3.2.3. It happens that we develop a tool to tell use where 
the class is loaded from. It tell us that the class is loaded in another web app's 
WEB-INF/llib(This web app never use the XML parser function of the jar, so the build 
script problem is not found before). We solve the problem and the application works 
fine in JBoss 3.2.3.

    (2)For release,  the release engineer use Jsper to pre-compile the JSP files to 
WEB-INF/classes. there is a hello.jsp file in each application, it is used to direct 
the request to a specific page in a  web  app. It is placed in the root of the web 
application (for example, mywebapp.war/hello.jsp). This hello.jsp is configured as a 
welcome file in web.xml.  We found that when we acces a web app, we are directed to 
the specified page in another web app. This never occurs in JBoss 3.0.8-Tomcat 4.1.24, 
so we can confirm that our build script does not place the generated classes 
incorrectly.



My question is, is it a bug of JBoss, or we have to make some addtional configuration 
for JBoss 3.2.3.



Thanks for your help.
