Maintain JCO Connections (activate)

Hi all,

I've my sld configured and in communication with J2EE and backend. Now I've to activate/create new JCO connection. At this moment the connection that i need is at "red state" and if i try to create it, i get the error message

System already exists in SLD, witch is true.

if I try to create with a unique name it says:

Failed to create new JCO client connection LCMG_R3_SelfServiceGenerics_MetaData: com.sap.tc.webdynpro.services.sal.sl.api.WDSystemLandscapeException: Error while obtaining JCO connection. at com.sap.tc.webdynpro.serverimpl.wdc.sl.SystemLandscapeFactory.getJCOClientConnection(SystemLandscapeFactory.java:150) at com.sap.tc.webdynpro.serverimpl.wdc.sl.SystemLandscapeFactory.createJCOClientConnection(SystemLandscapeFactory.java:356) at com.sap.tc.webdynpro.services.sal.sl.api.WDSystemLandscape.createJCOClientConnection(WDSystemLandscape.java:107) at com.sap.tc.webdynpro.tools.sld.ButtonBar.onActionFinish(ButtonBar.java:224) at com.sap.tc.webdynpro.tools.sld.wdp.InternalButtonBar.wdInvokeEventHandler(InternalButtonBar.java:265) at com.sap.tc.webdynpro.progmodel.generation.DelegatingView.invokeEventHandler(DelegatingView.java:87) at com.sap.tc.webdynpro.progmodel.controller.Action.fire(Action.java:67) at com.sap.tc.webdynpro.clientserver.task.WebDynproMainTask.handleAction(WebDynproMainTask.java:101) at com.sap.tc.webdynpro.clientserver.task.WebDynproMainTask.handleActionEvent(WebDynproMainTask.java:304) at com.sap.tc.webdynpro.clientserver.task.WebDynproMainTask.execute(WebDynproMainTask.java:659) at com.sap.tc.webdynpro.clientserver.cal.AbstractClient.executeTasks(AbstractClient.java:59) at com.sap.tc.webdynpro.clientserver.cal.ClientManager.doProcessing(ClientManager.java:251) at com.sap.tc.webdynpro.serverimpl.defaultimpl.DispatcherServlet.doWebDynproProcessing(DispatcherServlet.java:154) at com.sap.tc.webdynpro.serverimpl.defaultimpl.DispatcherServlet.doContent(DispatcherServlet.java:116) at com.sap.tc.webdynpro.serverimpl.defaultimpl.DispatcherServlet.doPost(DispatcherServlet.java:55) at javax.servlet.http.HttpServlet.service(HttpServlet.java:760) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at com.sap.engine.services.servlets_jsp.server.HttpHandlerImpl.runServlet(HttpHandlerImpl.java:390) at com.sap.engine.services.servlets_jsp.server.HttpHandlerImpl.handleRequest(HttpHandlerImpl.java:264) at com.sap.engine.services.httpserver.server.RequestAnalizer.startServlet(RequestAnalizer.java:347) at com.sap.engine.services.httpserver.server.RequestAnalizer.startServlet(RequestAnalizer.java:325) at com.sap.engine.services.httpserver.server.RequestAnalizer.invokeWebContainer(RequestAnalizer.java:887) at com.sap.engine.services.httpserver.server.RequestAnalizer.handle(RequestAnalizer.java:241) at com.sap.engine.services.httpserver.server.Client.handle(Client.java:92) at com.sap.engine.services.httpserver.server.Processor.request(Processor.java:148) at com.sap.engine.core.service630.context.cluster.session.ApplicationSessionMessageListener.process(ApplicationSessionMessageListener.java:33) at com.sap.engine.core.cluster.impl6.session.MessageRunner.run(MessageRunner.java:41) at com.sap.engine.core.thread.impl3.ActionObject.run(ActionObject.java:37) at java.security.AccessController.doPrivileged(Native Method) at com.sap.engine.core.thread.impl3.SingleThread.execute(SingleThread.java:100) at com.sap.engine.core.thread.impl3.SingleThread.run(SingleThread.java:170) Caused by: com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve connection parameter for LCMG_R3_SelfServiceGenerics_MetaData at com.sap.tc.webdynpro.serverimpl.wdc.sl.JCOClientConnection.resolveConnectionParameter4MsgServerJCODestination(JCOClientConnection.java:670) at com.sap.tc.webdynpro.serverimpl.wdc.sl.JCOClientConnection.resolveConnectionParameter(JCOClientConnection.java:486) at com.sap.tc.webdynpro.serverimpl.core.sl.AbstractJCOClientConnection.init(AbstractJCOClientConnection.java:252) at com.sap.tc.webdynpro.serverimpl.core.sl.AbstractJCOClientConnection.<init>(AbstractJCOClientConnection.java:226) at com.sap.tc.webdynpro.serverimpl.wdc.sl.JCOClientConnection.<init>(JCOClientConnection.java:106) at com.sap.tc.webdynpro.serverimpl.wdc.sl.SystemLandscapeFactory.getJCOClientConnection(SystemLandscapeFactory.java:148) ... 30 more Caused by: java.lang.NullPointerException at java.util.Hashtable.put(Hashtable.java:393) at com.sap.tc.webdynpro.serverimpl.wdc.sl.JCOClientConnection.resolveConnectionParameter4MsgServerJCODestination(JCOClientConnection.java:564) ... 35 more

Someone could help me activating a JCO connection or give me documentation for it !?

Thanks a lot.
