OK, I am trying to port an application from JBoss 4.0.1 to 4.2.3. I am now getting the error: java.lang.IllegalStateException: Cannot obtain target bean for: JuniperLNServlet I have searched extensively for this error both on Google and the JBoss site search function and cannot find anything. Any help would be appreciated. I am pretty much of a newbie with Web apps and services so I'm unsure of what I need to be looking at. To make things worse documentation for the application is nonexistent. JuniperLNServlet is a Web service. Because this is the first servlet defined in web.xml, it seems like the problem may be systemic and not specific to this servlet. To save space I am just including configuration code that is related to this servlet. If anybody has some ideas that makes them want to look at let me know and I will post that code. log | 15:31:55,752 INFO [DefaultWebAppDesciptorModifierImpl] Ignore servlet: lingonet.webservices.JuniperLNServlet | 15:31:55,752 INFO [DefaultWebAppDesciptorModifierImpl] Ignore servlet: lingonet.webservices.ConnectorLNServlet | 15:31:55,752 INFO [DefaultWebAppDesciptorModifierImpl] Ignore servlet: lingonet.webservices.ExampleResponseLNServlet | 15:31:55,768 INFO [DefaultWebAppDesciptorModifierImpl] Ignore servlet: lingonet.LoginServlet | 15:31:55,768 INFO [DefaultWebAppDesciptorModifierImpl] Ignore servlet: lingonet.EDSLoginServlet | 15:31:55,768 INFO [DefaultWebAppDesciptorModifierImpl] Ignore servlet: lingonet.UserCommander | 15:31:55,768 INFO [DefaultWebAppDesciptorModifierImpl] Ignore servlet: lingonet.ProjectCommander | 15:31:55,768 INFO [DefaultWebAppDesciptorModifierImpl] Ignore servlet: lingonet.SystemSettingsCommander | 15:31:55,768 INFO [DefaultWebAppDesciptorModifierImpl] Ignore servlet: lingonet.reports.ReportImageServlet | 15:31:55,768 INFO [DefaultWebAppDesciptorModifierImpl] Ignore servlet: javax.faces.webapp.FacesServlet | 15:31:55,830 ERROR [MainDeployer] Could not create deployment: file:/C:/jboss-4.2.3.GA/server/default/tmp/deploy/tmp24788app.ear-contents/web.war | java.lang.IllegalStateException: Cannot obtain target bean for: JuniperLNServlet | at org.jboss.wsf.container.jboss42.ModifyWebMetaDataDeploymentAspect.create(ModifyWebMetaDataDeploymentAspect.java:58) | at org.jboss.wsf.framework.deployment.DeploymentAspectManagerImpl.deploy(DeploymentAspectManagerImpl.java:118) | at org.jboss.wsf.container.jboss42.ArchiveDeployerHook.deploy(ArchiveDeployerHook.java:97) | at org.jboss.wsf.container.jboss42.DeployerInterceptor.create(DeployerInterceptor.java:79) | at org.jboss.deployment.SubDeployerInterceptorSupport$XMBeanInterceptor.create(SubDeployerInterceptorSupport.java:180) | at org.jboss.deployment.SubDeployerInterceptor.invoke(SubDeployerInterceptor.java:91) | at org.jboss.mx.server.Invocation.invoke(Invocation.java:88) | at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:264) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:659) | at org.jboss.mx.util.MBeanProxyExt.invoke(MBeanProxyExt.java:210) | at $Proxy45.create(Unknown Source) | at org.jboss.deployment.MainDeployer.create(MainDeployer.java:969) | at org.jboss.deployment.MainDeployer.create(MainDeployer.java:959) | at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:818) | at org.jboss.deployment.MainDeployer.deploy(MainDeployer.java:782) | at sun.reflect.GeneratedMethodAccessor21.invoke(Unknown Source) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:597) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) | at org.jboss.mx.server.Invocation.dispatch(Invocation.java:94) | web.xml | <servlet> | <servlet-name>JuniperLNServlet</servlet-name> | <servlet-class>lingonet.webservices.JuniperLNServlet</servlet-class> | </servlet> | <servlet-mapping> | <servlet-name>JuniperLNServlet</servlet-name> | <url-pattern>/JuniperLN</url-pattern> | </servlet-mapping> | webservice.xml | <webservice-description> | <webservice-description-name>JuniperLNService</webservice-description-name> | <wsdl-file>WEB-INF/wsdl/JuniperLNService.wsdl</wsdl-file> | <jaxrpc-mapping-file>WEB-INF/junipermapping.xml</jaxrpc-mapping-file> | <port-component> | <port-component-name>JuniperLN</port-component-name> | <wsdl-port xmlns:my="http://lingonet.lingosys.com">my:JuniperLNPort</wsdl-port> | <service-endpoint-interface>lingonet.webservices.JuniperLN</service-endpoint-interface> | <service-impl-bean> | <servlet-link>JuniperLNServlet</servlet-link> | </service-impl-bean> | </port-component> | </webservice-description> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4177917#...
