I have set up a VPC with the following things installed: Windows XP Pro running on a VPC 2.6 CR2 downloaded with AS packaged. SQL Server 2000 JDBC Connector Version 1.1.15.01.101 downloaded from Microsoft Installed everything as the help file said but am getting an error when accessing http://localhost:8080/portal. type Exception report | | message | | description The server encountered an internal error () that prevented it from fulfilling this request. | | exception | | javax.servlet.ServletException: Servlet execution threw an exception | org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81) | | | root cause | | java.lang.NoClassDefFoundError: org/apache/commons/httpclient/HttpMethod | org.jboss.portal.server.servlet.PortalServlet.service(PortalServlet.java:274) | javax.servlet.http.HttpServlet.service(HttpServlet.java:810) | org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81) And this is from the log files: 2007-06-11 10:34:30,500 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/portal].[PortalServletWithPathMapping]] Servlet.service() for servlet PortalServletWithPathMapping threw exception | java.lang.NoClassDefFoundError: org/apache/commons/httpclient/HttpMethod | at org.jboss.portal.server.servlet.PortalServlet.service(PortalServlet.java:274) | at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:81) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) | at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) | at org.jboss.web.tomcat.security.CustomPrincipalValve.invoke(CustomPrincipalValve.java:39) | at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:159) | at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:407) | at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:59) | at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) | at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) | at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) | at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) | at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:856) | at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConnection(Http11Protocol.java:744) | at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) | at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) | at java.lang.Thread.run(Unknown Source) Any ideas?
