simple db-jpa-ejb-servlet
Hello,
I'm trying to build simple test application with following structure:
servlet-ejb-jpa-database
Application works well, but when I try to call from servlet ejb, witch call
jpa I got error at servlet. Data from db is correctly return via jpa becouse
I see it in ejb classs using simple System.out.println.
Additional I call simple ejb method sayHello (returning just text) without
connection to db and it works well. So at this moment I haven't idea what is
wrong. It you would like to see my maven project, it's here:
http://iem.pw.edu.pl/~wojciecs/test_ejb_jpa_servlet.7z. I think problem at
communication between servlet and ejb. I use tomcat 7.0.27 with openejb 4
Best Regards
sw

hmm,
i tested this way:
1) added tomee plugin to your pom:

Hello,
I'm still testing this configuration and just switch local call bean to
remote call repleacing:
p.put(Context.INITIAL_CONTEXT_FACTORY,

p.put("java.naming.provider.url", "http://127.0.0.1:8080/tomee/ejb");
Now I got error: 2012-06-14 20:59:50 org.apache.openejb.client.EventLogger
log
SEVERE: RequestFailed{server=http://127.0.0.1:8080/tomee/ejb}
JNDI_LOOKUPnull:/OsakaImpRemote
Tomme jndi browser shows: JNDI Name OsakaImpRemote.
Local call ejb still works with name OsakaImpRemote.
What is incorrect?
