Hi, I'm trying to isolate a WAR file as described on:
http://www.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration In my small example I'm trying to force a servlet to a use version of Xerces that I distribute with the servlet (located under WEB-INF/lib). It fails during deployment with the following exception: 10:52:52,967 INFO [STDOUT] JDOM Exception: org.jdom.JDOMException: Could not load default SAX parser: org.apache.xerces .parsers.SAXParser:

org.jboss.web.tomcat.tc4.EmbeddedTomcatService.performDeploy(EmbeddedTomcatService.ja va:309) However, the application apparently works as intended. It prints out Xerces version 2.6.2 and not 2.0.1 which is bundled with JBoss. But I do not like the exception during deployment. Anyway to get rid of it? If I tell Tomcat to isolate war files globally (by editing deploy/jbossweb-tomcat41.sar/META-INF/jboss-service.xml) the situation is worse. When the web-console is deployed NullPointerExceptions are thrown. My servlet deploys fine. However, it does not write the correct version of Xerces when I hit the servlet (2.0.1 and not 2.6.2 which is the one I distribute). My code is below. Any suggestions to what is going on. Is it at all possible to distribute ones own XML parser? | import org.apache.xerces.impl.Version; | | import java.io.*; | | import javax.servlet.http.*; | import javax.servlet.*; | | public class HelloServlet extends HttpServlet { | public void doGet(HttpServletRequest req, | HttpServletResponse res) | throws ServletException, IOException { | PrintWriter out = res.getWriter(); | | System.out.println("I'm hit. I'm using Xerces version " + Version.fVersion); | out.println("Hello, world!"); | out.println("I'm using Xerces version " + Version.fVersion); | out.close(); | } | } | My jboss-web.xml looks like this: | <?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> | <class-loading java2ClassLoadingCompliance="false" > | <loader-repository> | jboss.cl.test:loader=JBossCLExample.war | <loader-repository-config> | java2ParentDelegaton=false | </loader-repository-config> | </loader-repository> | </class-loading> | </jboss-web> | My web.xml looks like this: | <?xml version="1.0" encoding="UTF-8"?> | | <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd";> | <web-app> | | <servlet> | <servlet-name>hello</servlet-name> | <servlet-class>HelloServlet</servlet-class> | </servlet> | | <servlet-mapping> | <servlet-name>hello</servlet-name> | <url-pattern>/hello</url-pattern> | </servlet-mapping> | | </web-app> | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3848284#3848284 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3848284 ------------------------------------------------------- This SF.Net email is sponsored by: thawte's Crypto Challenge Vl Crack the code and win a Sony DCRHC40 MiniDV Digital Handycam Camcorder.
