If you looked through the api, the next thing you should do is to look trough
the sourcecode (
it is such a good part of documentation) to see how comparable methods have
implemented this. You'll be surprised how simple it is. Just learn HQL.

Ah, thank you. I'll try that.
One other approach that I have is to build the app and take apart the EAR file.
Often it's easier to go from that direction than it is to try to understand a
complicated build.xml.

I'm having trouble obtaining a reference to an EJB entity bean in a portlet.
The entity bean has successfully deployed and I've confirmed the JNDI name in

I had first tried to obtain the reference through the EJB annotation, injecting
it into the portlet as such:

That's a normal validation failure, since there actually aren't any beans yet.
You can silence it by editing the EJB's META-INF/ejb-jar.xml file and taking
the schema attribute off the opening ejb-jar
Your Interface(Query) should contain getJon, setJon and the destroy methods.
You are calling methods on the interface from your view pages and they havent
been defined there.

Do you have a firewall, such as iptables, running on the server? If you have
not opened port 81 in iptables, it will not work.
Are you running SELinux? Can't recall if that is on SUSE (lately I am using

For running the JEMS installer, You need a GUI.
Follow the steps given below.
1. You have to set the DISPLAY environment variable.

3. Then, Run the JEMS installer.
I hope, this will solve your problem.
I think thats a seam bug. Seam tries to interpolate any expressions in the
