Hi I'm trying to write an EJB application from scratch, and to be honest im kind of lost. I have created my EJB and it seems to be deployed ok and my client side app is deploying but throwing the following error | INFO [[/UoD]] Marking servlet Servlet as unavailable | ERROR [[/UoD]] Error loading WebappClassLoader | delegate: false | repositories: | ----------> Parent Classloader: | java.net.FactoryURLClassLoader@83dae1 | org.UoD.Control.Servlet | java.lang.ClassNotFoundException: org.UoD.Control.Servlet | at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1358) | at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1204) | at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1083) | at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:806) | at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:129) | at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) | at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:179) | at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) | at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) | at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) | at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) | at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) | at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262) | at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) | at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) | at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) | at java.lang.Thread.run(Thread.java:595) | 10:55:53,103 ERROR [[Servlet]] Allocate exception for servlet Servlet | java.lang.ClassNotFoundException: org.UoD.Control.Servlet | at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1358) | at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1204) | at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:1083) | at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:806) | at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:129) | at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) | at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:179) | at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) | at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) | at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) | at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) | at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) | at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262) | at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) | at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) | at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) | at java.lang.Thread.run(Thread.java:595) | I found online that maybe i should be building my src code into ../WEB-INF/classes/ so i tried that and the same still occurs. my servlet declaration in the web.xml is as such: | <servlet> | <servlet-name>Servlet</servlet-name> | <servlet-class>org.UoD.Control.Servlet</servlet-class> | </servlet> | | <servlet-mapping> | <servlet-name>Servlet</servlet-name> | <url-pattern>/servlet</url-pattern> | </servlet-mapping> | any advice on where to look or where i am going wrong would really help View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4212916#4212916 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4212916

[EJB 3.0] - Re: JVM container?

by Wolfgang Knauf

Hi, I will answer question 2, hopefully this gives the right hints to answer question 1 (which I do not understand fully ;-) ). The "Container" is the app server, which is the container for the EJB implementation. A "remote client" could also be defined as a different process (another java.exe listed in task manager) of your operating system. The communication between the client process and the server process is handled the same way is if they were on different machines: the client connects to a specific port on the server machine. I hope this helps Wolfgang View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4212903#4212903 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4212903

Thanks for ur reply... yes i can connect it now from java file......... but on jboss portal i m not able to get the output ... i need to write using portlet language...

[JBoss Messaging] - Notification when Topic is destoyed

by alfred.rsa

Hi We are using JBM 1.4 SP3 and our applications uses a topic to send messages. We look up the connection factory, create a connection and set an ExceptionListener on the connection. My problem is that an exception is only fired when JBM is shut down and not when the Topic is destroyed. If the Topic is destroyed and recreated, the clients never knows about this and never resubscribes. Is there any way we could also get the exception to fire when the Topic is destroyed?

[EJB 3.0] - How do I build a query with Dates in EJB QL ?

by dimar1975

Hi all ! I have an EJB 3 Entity bean which issues some queries. The Queries include some Date field in the WHERE clause SELECT OBJECT(a) FROM TaskList AS a WHERE a.taskEndDate ='2004-09-01' Unfortunately Hibernate seems doesn't like it at all....it issues a org.hibernate.exception.DataException: could not execute query and beneath it: ORA-01861: literal does not match format string Unfortunately I cannot use named parameters in my Query. Query are stored in the DB as shortcuts so they have the Date hardcopied in it. Is there a to_date equivalent in HSQL ? any help? thanks marco View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4212895#4212895 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4212895

[JBoss jBPM] - Assignment Handler gets wrong ProcessInstance ID

by wurzelbutz

Hello (: I'm using an Assignment Handler to assign my tasks to users and there is a strange issue: public void assign(Assignable arg0, ExecutionContext arg1) throws Exception { | System.out.println("AH-PID:"+arg1.getProcessInstance().getId()); | System.out.println("AH-TN-ID:"+arg1.getTaskInstance().getTask().getTaskNode().getId()); | ... read target user from DB and assign .. | } | Here is what i do: 1.) Start a new process with >1 TaskNodes(each containing at least 1 task). The processInstance has ID 16. Assignment Handler is called. AH-PID=16 --> OK AH-TN-ID=3424 --> OK 2.) Start first tasknode 3.) End first tasknode. TN is ended as expected. Assignment handler is called for the next TN. AH-TN-ID=3425 --> OK AH-PID=17 --> Why? I dont have a processInstance with ID 17. i did some debugging and noticed that the startDate of ProcessInstance 17 is the same as the current date. What is the correct way to read the current processInstance inside the Assignment Handler? br Hugo View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4212888#4212888 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4212888
