Windchill InfoEngine API's not working through Proxy Connection

[ashishbhusa]

Hello,

We have an environment where we are trying to connect to Windchill 11.0.

Windchill is setup in SSL mode and we connecting through HTTPS proxy.

We are using standalone application to Query a part, using SimpleTaskDispatcher and InfoEngine API's.

Windchill application certificate is also added in the truststore.

Below is sample code :

IeConnectionFactory f1 = new IeConnectionFactory();
IeConnectionSpec connSpc = new IeConnectionSpec();

connSpc.setUserName(userName);
connSpc.setPassword(password);
connSpc.setProperty("ConnectionURL",url + "/servlet/SimpleTaskDispatcher" );

javax.resource.cci.Connection windchillConnection = f1.getConnection(connSpc );
WindchillDAO dao = new WindchillDAO(windchillConnection);
dao.Query("wt.part.WTPart", " name = TestPart ", null, new String[]{"*"});

We have set below JAVA_OPTS :

1) https.proxyHost

2) https.proxyPort

3) https.nonProxyHosts

We are getting below exception  :

Need help on how to use InfoEngine API's with Proxy Connection.
