[JBoss Seam] - Seam throws exception while working with DataModel

by lamerbot

Hello. I'm new to seam and i want to integrate seam capability with AndroMDA product. I use AndroMDA for generating EJB3 and DAOs. I made a simple application that allows users login and see userlist. There are some strangeness: After user login he able to see userslist. There are an link to CreateNewUser from that page. When user created it's rediercts toViewAllUsers. All work's fine, but: When i add capability to delete User (delete button in userlist according to seam examples) i got an error: | 12:07:22,138 ERROR [[Faces Servlet]] Servlet.service() for servlet

What i am trying to do is creating a MBEAN through which we can change the values through jmx console. and my application will read all the values from this mbean. i have created one interface and one class which implements the interface. when i try to compile the build it says build suceesful and i also can see the sar file in the server>default>deploy folder. but imedidately after i am getting this exception. 13:05:11,758 ERROR [MainDeployer] could not create deployment: file:/C:/jboss-4.0.1/server/default/deploy/blog_example.sar org.jboss.deployment.DeploymentException: No ClassLoaders found for: blog.example.services.BlogExampleService; - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: blog.example.services.BlogExampleService) at org.jboss.system.ServiceConfigurator.install(ServiceConfigurator.java:143) at org.jboss.system.ServiceController.install(ServiceController.java:200) at sun.reflect.GeneratedMethodAccessor46.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:144) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:80) at org.jboss.mx.server.Invocation.invoke(Invocation.java:72) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:249) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:642) at org.jboss.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:177) at $Proxy4.install(Unknown Source) at org.jboss.deployment.SARDeployer.create(SARDeployer.java:208) at org.jboss.deployment.MainDeployer.create(MainDeployer.java:918) at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:774) at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:738) at sun.reflect.GeneratedMethodAccessor47.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:144) at org.jboss.mx.server.Invocation.dispatch(Invocation.java:80) at org.jboss.mx.interceptor.AbstractInterceptor.invoke(AbstractInterceptor.java:122) at org.jboss.mx.server.Invocation.invoke(Invocation.java:74) at org.jboss.mx.interceptor.ModelMBeanOperationInterceptor.invoke(ModelMBeanOperationInterceptor.java:131) at org.jboss.mx.server.Invocation.invoke(Invocation.java:74) at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:249) at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:642) at org.jboss.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:177) at $Proxy8.deploy(Unknown Source) at org.jboss.deployment.scanner.URLDeploymentScanner.deploy(URLDeploymentScanner.java:305) at org.jboss.deployment.scanner.URLDeploymentScanner.scan(URLDeploymentScanner.java:481) at org.jboss.deployment.scanner.AbstractDeploymentScanner$ScannerThread.doScan(AbstractDeploymentScanner.java:204) at org.jboss.deployment.scanner.AbstractDeploymentScanner$ScannerThread.loop(AbstractDeploymentScanner.java:215) at org.jboss.deployment.scanner.AbstractDeploymentScanner$ScannerThread.run(AbstractDeploymentScanner.java:194) Caused by: java.lang.ClassNotFoundException: No ClassLoaders found for: blog.example.services.BlogExampleService at org.jboss.mx.loading.LoadMgr3.beginLoadTask(LoadMgr3.java:198) at org.jboss.mx.loading.RepositoryClassLoader.loadClassImpl(RepositoryClassLoader.java:464) at org.jboss.mx.loading.RepositoryClassLoader.loadClass(RepositoryClassLoader.java:374) at java.lang.ClassLoader.loadClass(ClassLoader.java:235) at org.jboss.mx.server.MBeanServerImpl.instantiate(MBeanServerImpl.java:1183) at org.jboss.mx.server.MBeanServerImpl.instantiate(MBeanServerImpl.java:269) at org.jboss.mx.server.MBeanServerImpl.createMBean(MBeanServerImpl.java:327) at org.jboss.system.ServiceCreator.install(ServiceCreator.java:125) at org.jboss.system.ServiceConfigurator.internalInstall(ServiceConfigurator.java:153) at org.jboss.system.ServiceConfigurator.install(ServiceConfigurator.java:118) ... 33 more plzzzzz help me what to do now.

[JBoss Seam] - Re: Seam promote bad design?

by evdelst

I use pageflows for the navigation, the beans don't contain any navigation and I call the action methods using expressions in the flow. In the views, the buttons return the transitions to use. It is a pretty clean seperation I think.

[JBoss Seam] - Re: Seam + ScopeType.EVENT

by paul＠xfact.nl

This is comparable with a request scope. For exampe a page with a backing bean that can submit data, the backing bean can give feedback, but the data is not saved after that. Example: | <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" | "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> | <html xmlns="http://www.w3.org/1999/xhtml" | xmlns:s="http://jboss.com/products/seam/taglib" | xmlns:ui="http://java.sun.com/jsf/facelets" | xmlns:f="http://java.sun.com/jsf/core" | xmlns:h="http://java.sun.com/jsf/html" | xmlns:c="http://java.sun.com/jstl/core"> | <body> | <ui:define name="body"> | <h:form id="frm_Hello"> | Please fill in your name: <h:inputText id="txt_Name" | value="#{hello.name}" /> | <h:commandButton id="btn_sayHello" value="Say Hello!" | action="#{hello.sayHello}" /> | <br/> | <h:outputText id="greeting" value="Hello #{hello.name}" | rendered="#{not empty hello.name}" /> | </h:form> | </ui:define> | </body> | </html> | | package seamdemo.hello.backingbeans; | | import javax.ejb.Remove; | import javax.ejb.Stateful; | | import org.jboss.seam.ScopeType; | import org.jboss.seam.annotations.Destroy; | import org.jboss.seam.annotations.Name; | import org.jboss.seam.annotations.Scope; | | @Stateful | @Scope(ScopeType.EVENT) | @Name("hello") | public class HelloBean implements Hello { | private String name; | | public String getName() { | return name; | } | | public String sayHello() { | return ""; | } | | public void setName(String name) { | this.name = name; | } | | @Remove @Destroy | public void destory() { | } | } | After showing the entered name, the name is not saved. So if you reload the page, the textfield is empty again.

[JBossWS] - Re: org.jboss.ws.WSException: Cannot obtain UnifiedBeanMetaD

by PhFery

Hi! I think you should replace: <webservices ejb-link="ResponderBean" append="true"/> with following code: <webservices ejb-link="Responder" append="true"/> I think you must use the ejb-name to locate your bean ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3989617#3989617 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3989617

[JBoss Seam] - Re: Timer issue just broke my site after a week of no issues

by gavin.king＠jboss.com

You probably need to ask about this in the EJB3 forum. But you at least need to show us the stacktrace of the NPE.

[Beginners Corner] - Re: EJB entity with static final field

by buggsbunny101

Yes this is exactly how I want too use it. Thanks. Now, another question: Because I will need this "constant" outsite the EJB and because the bean definition is not availlable outside, How can I define this constant? I use XDoclet to generate my classes and interfaces. Is there a way to tell it to "export" this static final field in the generated class? (interfaces and dataClasses)? Should I define some function giving me the constant value? (Bhaaaaa! Sound really dirty) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3989615#3989615 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3989615
