Address already in use: connect

Question

Dear all,I've got always this following exception, if I get three times the method getDimensionTree. This method simply reads one dimension tree in Essbaseand constructs a DataTreeModel (like JTree) with the member names.The source is like a sample code from Hyperion, but whyever it is crashing using the EES 6.5 with Essbase 6.5.3.I believe, that the connections aren't removed. But however the getConnections-iterator is always returning null. And I debug the logsbefore and after a connect and disconnect, to be sure everything is closed.I tried this with Essbase 7.0 and EDS 7.0 and it works perfect, but I am not allowed to use the version 7 because of other tools combination. There I am using the m_olapServer.connect(true, false), whichis not available at the 6.5 JAPI. Therefore there is apublic void connect(boolean useEesSvrAtOlapSvrNode) throws EssException with useEesSvrAtOlapSvrNode - If true, the enterprise server at the node where this olap server resides is used to traffic the requests between the JAPI client and the olap server. If false, the enterprise server that authenticated the user is used to traffic the requests.but I cannot understand the sense of the parameter flag. But I think that this doesn't matter.22:03:15,171 ERROR [EssbaseQuery] com.essbase.api.base.EssException: Cannot connect to enterprise server.
