Configuring a JCE Provider

The Java Cryptography Extension (JCE) provider included with J2SE 1.4.x does not support RSA encryption. Because the XML Encryption defined by WS-Security is typically based on RSA encryption, in order to use WS-Security to encrypt SOAP messages you must download and install a JCE provider that supports RSA encryption.

RSA is public-key encryption technology developed by RSA Data Security, Inc. The acronym stands for Rivest, Shamir, and Adelman, the inventors of the technology.

If you are running the Application Server on version 1.5 of the Java SDK, the JCE provider is already configured properly.
