Integration

Hi,
I'm try to invoke CRM On Demand web service for which there is a pre-req to get a session ID by making an https request. I've the below java embedded code which does that. It works fine if I run the below code in my desktop as a java program, but when I deploy it on SOA 11g I get "Caused by: java.lang.IllegalStateException: Cipher not initialized" error (find below the stack trace). Please let me know what's going wrong here?
------
String sessionString = "FAIL";
String wsLocation =
"https://secure-********.crmondemand.com/Services/Integration";
String headerName;
try {
// create an HTTPS connection to the OnDemand webservices
java.net.URL wsURL =
new java.net.URL(wsLocation + "?command=login");
java.net.HttpURLConnection wsConnection =
(java.net.HttpURLConnection)wsURL.openConnection();
// disable caching
wsConnection.setUseCaches(false);
// set some http headers to indicate the username and password we are using to logon
wsConnection.setRequestProperty("UserName",
"***************/**********");
wsConnection.setRequestProperty("Password", "***********");
wsConnection.setRequestMethod("GET");
// see if we got a successful response
if (wsConnection.getResponseCode() ==
java.net.HttpURLConnection.HTTP_OK) {
// get the session id from the cookie setting
for (int i = 0; ; i++) {
headerName = wsConnection.getHeaderFieldKey(i);
if (headerName != null &&
headerName.equals("Set-Cookie")) {
// found the Set-Cookie header (code assumes only one cookie is being set)
sessionString = wsConnection.getHeaderField(i);
if (sessionString != null ||
sessionString.startsWith("JSESSIONID")) {
break;
}
}
}
String formattedID =
sessionString.substring(sessionString.indexOf("=") + 1,
sessionString.indexOf(";"));
setVariableData("SessionID", formattedID);
//System.out.println("Session ID: " + sessionString);
}
} catch (Exception e) {
e.printStackTrace();
setVariableData("SessionID", e.getMessage());
System.out.println("Logon Exception generated :: " + e);
throw new RuntimeException(e);
}
