I use XMLBeans with quite a number of our Java servlet/JSP applications. After compiling the Java objects from schema, I store the xmltypes.jar file in the %WEBAPP%/WEB-INF/lib directory. So they don't need to be bundled with each WAR file, I put a single copy of xbean.jar and jsr173_api.jar in the %TOMCAT_HOME%/common/lib directory.
Instead of trying to use <jsp:usebean/> tags to use the beans in XML pages, I just instantiate the XMLObject as needed, then store it as an attribute in the session. The first JSP page that needs the XMLObject starts by looking for the XMLObject in the session, and if not there - it instantiates it. All subsequent JSP pages that need the XMLObject just fetch it from the session. If not found in the session, then I use <jsp:forward/> to return to the "first" page that initially created the XMLObject. When no longer needed, I clear the XMLObject from the session.

I receive the following exception from tomcat: org.apache.jasper.JasperException: /premis.jsp(1,1) The value for the useBean class attribute gov.loc.standards.premis.PremisDocument is invalid. JSP requires that I specify the package followed by the public class that I wish to use. So, assuming the package was com.test and the class was TestBean.class I would include the following: <jsp:useBean id="theBean" class="com.test.TestBean"/> With my xmlbean, I have identified the package, gov.loc.standards.premis, and what I believe is the root element, PremisDocument. <jsp:useBean id="theBean" class="gov.loc.standards.premis.PremisDocument"/> However, this seems to declare the interface rather than the class, and if I understand correctly, there is no xmlbean constructor of that name taking no arguments. Is this correct? I think that tomcat maybe requires the class and constructor to be present. I'm new to tomcat, so not sure if deploying the xmlbean would be possible anyway, especially considering the dependencies on the org.apache.xmlbeans class, but would appreciate any ideas to solve this. Alternatively, if anyone's aware that this isn't possible could someone point that out so I can move on!
