Maintain JCO Connections (activate)

[Former Member]

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.

Hi folks,

thanks for your answers, it was for extreme help.

Now i can configure the JCO and activate (green).

But I've JCO connection that is in red state and if I try to create it it says :

Failed to create new JCO client connection SAP_R3_SelfServiceGenerics_MetaData: com.sap.tc.webdynpro.services.sal.sl.api.WDSystemLandscapeException: Connection SAP_R3_SelfServiceGenerics_MetaData already exists in the SLD. Please choose another name. at com.sap.tc.webdynpro.serverimpl.wdc.sl.SystemLandscapeFactory.createJCOClientConnection(SystemLandscapeFactory.java:272)

Remove buttom is unavailable. Do you know why this happens?

JCO SAP_R3_SelfServiceGenerics works fine (test and ping).

Thanks.

Pedro

Hi Pedro,

May be that SAP_R3_SelfServiceGenerics_MetaData already exists on the SLD. Go to the SLD and try to remove this JCO Destination. After that try creating it again from the "Maintain JCO Destinations" on the console Admin.

Hi,

Try this:

1. Open http://<yourserver>:<port>/sld

2. Navigate to content maintenance

3. Navigate to subset: landscape definition

Class JCO message server destination & JCO application server destination

Delete everything that doesn't belong there.

Hi,

Accessing the System SLD

try {

// Get the required CIMClient object

com.sap.lcr.api.cimclient.CIMClient

cimClient = WDSystemLandscapeFactory.getClient();

// Get accessor for message server objects

SAP_BCMessageServerAccessor acc = new SAP_BCMessageServerAccessor (cimClient);

instances = acc.enumerateInstances(false, true, null);

// Loop the list of instances

for (int i = 0; i < instances.length; i++) {

SAP_BCMessageServer msgServer

= (SAP_BCMessageServer) instances<i>.getJavaCIMObject();}

System.out.println (msgServer.getCaption());

}

} catch (Exception e) {

throw new WDSystemLandscapeException ("Failed to access system landscape”, e);

}

Jco Client Connection

WDJCOClientConnection client =

WDSystemLandscape.getJCOClientConnection(“myJCOClient”);

// Create JCO clients using load-balanced access

Hi,

Please tell me how Accessing the System SLD is the http://host:pot/sld?

and how edit

try {

com.sap.lcr.api.cimclient.CIMClient

cimClient = WDSystemLandscapeFactory.getClient();

// Get accessor for message server objects

SAP_BCMessageServerAccessor acc = new SAP_BCMessageServerAccessor (cimClient);

= (SAP_BCMessageServer) instances.getJavaCIMObject();}

System.out.println (msgServer.getCaption());

}

} catch (Exception e) {

throw new WDSystemLandscapeException ("Failed to access system landscape”, e);

}
