Subject OpenEJB+Tomcat+Oracle+Toplink
Date Fri, 20 Feb 2009 12:19:58 GMT

Hello ,

In my project i am using OpenEJB with Tomcat and  Oracle 10g with Toplink as
provider
I have problems configuring the persistence units and/or datasources. I am
not quite sure what the problem is.
The structure of ejb jar folder is:
-projectjar.jar
    --com	
    --META-INF,
where in META-INF folder i have only two xml files
    -- ejb-jar.xml
    -- persistence.xml
Because i have two database, i have two persistence-unit with different
names PUM and PUL
Content of persistence.xml is:
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

In openejb.xml i put
<Resource id="DBM" type="DataSource">
  JdbcDriver oracle.jdbc.OracleDriver 
  JdbcUrl jdbc:oracle:thin:@server:1521:db 
   UserName user
   Password user
</Resource> 
<Resource id="DBL" type="DataSource">
   JdbcDriver oracle.jdbc.OracleDriver 
   JdbcUrl jdbc:oracle:thin:@server:1521:db 
   UserName user2
   Password user2
</Resource> 

Oracle driver i put in lib folder on tomcat.
Аctually, we migrate from Glassfish to Tomcat. On Glassfish everything works
fine.

I hope that someone can help me out with this.
Thanks in advance.
