[Wyn Thomas]

A java client attempting an SSL connection to WLS 6.1 sp3 generates
the following error since migration from 5.1 sp9...

Client code as follows...

private Context getInitialContextSSL() throws Exception
{
Environment env = new Environment();
_providerURL = protocol + "s://" + ipAddress + ":" + sslPortNo;
env.setProviderUrl(_providerURL);

// First set the security credentials. These are the user-id and the
digital certificate and are
// used by WebLogic to authenticate the client.

FileInputStream certFileStream = new FileInputStream(clientCert);
InputStream certStream = new
PEMInputStream(certFileStream);
X509 x509 = new X509(certStream);
env.setSecurityCredentials(new
DefaultUserInfoImpl(_securityPrincipal, x509));

// Now set the client certificate and private key which will be used
for the SSL connection.

InputStream[] streams = new InputStream[2];
FileInputStream fis = new FileInputStream(clientPrivateKey);
streams[0] = new PEMInputStream(fis);
streams[1] = certStream;

env.setSSLClientCertificate(streams);
return env.getInitialContext();
}

Can anyone shed any light on this?

Thanks in advance.
