The following assumes you are using JDK 1.3 and the files were extracted to the d:\JaasExample directory. You will save some work by extracting the files to this directory otherwise you will have to modify the policy and the ResourceSecurity.xml policy files with the correct path names.
1) Copy the jaas.jar and the jaasmod.jar to your JDK jre\lib\ext directory (i.e. D:\JDK1.3\jre\lib\ext).
2) Add the following to the end of the java.security file located in JDK's jre\lib\security directory (i.e. D:\JDK1.3\jre\lib\security): auth.policy.provider=com.ibm.resource.security.auth.XMLPolicyFile
<%@ taglib uri="/tags/struts-logic" prefix="logic" %> <%-- welcome.jspRedirect default requests to Welcome global ActionForward.By using a redirect, the user-agent will change address to match the path of our Welcome ActionForward. --%>
