Question on JBoss Portal in cluster

[andytsoy]

Dear all,
JBoss 4.0.3ps1 + JBoss Portal 2.2.1sp1

In my cluster, there are 2 nodes.
When I start JBoss in node A, I can view the Portal and login.

When I start JBoss in node B, I can also view the Portal, however, it is directed to the login page instead of the default page. When I login with admin/admin, it has error:HTTP Status 401. But interestingly, if I login with a wrong login username or password, it can detect my login is incorrect.

It means it can know whether my login is correct but can't direct to the default page, do anyone know why?

If your configuration uses Apache+Mod_JK+Tomcat, you might want to check the worker.properties file in apache/conf for the sticky session settings. This is explained in more detail here - http://wiki.jboss.org/wiki/Wiki.jsp?page=UsingMod_jk1.2WithJBoss
