I am trying to connect a UDS System from a Weblogic 7.0 sp1 server. My application is deployed as an ear file and when I try to open a SSL connection I am getting the following exception.

javax.net.ssl.SSLHandshakeException: FATAL Alert:HANDSHAKE_FAILURE - The handshake handler was unable to negotiate an acceptable set of security parameters.

The program is running normal from a command prompt.

Hoping somebody have idea about this problem and suggest how to resolve it?

This error could be caused by the server and the client not being able to agree on a common ciphersuite. Try turning ssl debug on, this might provide more info:
-Dssl.debug=true -Dweblogic.StdoutDebugEnabled=true

The set of ciphersuites that can be used by ssl on server is affected by the server ssl configuration, or the ssl license strength - export/domestic.
See http://e-docs.bea.com/wls/docs70/secintro/concepts.html#1058675
