J2EE development with Oracle products

When you update the JVM of OC4J you must also change following security parameters in the java.security file to prevent a java.lang.SecurityException:   

• auth.policy.provider=oracle.security.jazn.spi.PolicyProvider 
• login.configuration.provider=oracle.security.jazn.spi.LoginConfigProvider

In the standard JVM configuration the appropriated JVM security definition file will be located in:  /usr/java1.4.x/jre/lib/security/java.security
