Certificate not Trusted

[xsp...@gmail.com]

I am trying to get an XML request sent into the WebSphere server.
When I send the request I am getting a Certificate Not Trusted error.
I realize this is probablly not a WebSphere issue, but I don't have
anywhere else to turn. I have installed the local certificate on my
browser and it likes it. Here is the code I am using?

private String xmlMsg = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
System.setProperty("java.protocol.handler.pkgs",
"com.ibm.net.ssl.internal.www.protocol");
//
URLConnection uc = new URL("https://localhost:7443/webapp/wcs/stores/
servlet/").openConnection();
uc.setDoOutput(true);
BufferedWriter wr = new BufferedWriter(new
OutputStreamWriter(uc.getOutputStream(), "UTF-8"));
wr.write(xmlMsg);
wr.flush();

Here is the error I am seeing:
javax.net.ssl.SSLHandshakeException:

When you say "I am trying to get an XML request sent into the
WebSphere server"
What exactly do you mean and from where?
