Roo on Weblogic 10.3.3 JPA?

[Mark Davis]

Hi folks - digging this out from the "EAR creation in Roo" thread as it's off topic for that one. Has anyone been able to successfully deploy a roo project on Weblogic 10.3.x? I am getting the following error:

Caused By: weblogic.deployment.EnvironmentException: Error loading the persisten
ce descriptor WEB-INF/lib/_wl_cls_gen.jar!/META-INF/persistence.xml from the mod
ule rooperson.war.  See the following stack trace for nested errors: weblogic.de

Any suggestions - I'm a roo newb. I tried adding a weblogic.xml file to web-inf dir with the following:

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app" xmlns:j2ee="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.2/weblogic-web-app.xsd">
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
</weblogic-web-app>

All I'm trying is a simple one-entity roo project with hibernate persistence. OpenJPA produced different errors.

Hi,
Try using the 1.0 schema version in persistence.xml - JPA 2.0 features will still work except setting new elements/attributes of the 2.0 schema like <shared-cache-mode>NONE</shared-cache-mode> for example.

-<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
+<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

thank you

I wonder if deploying to a different web server is not an option...

Like tc server or tomcat. I'll save a lot of time/pain.

I just wonder

Thx

Good suggestion, but tc server (and enhanced version of Tomcat) and Tomcat are only servlet/jsp containers - they do not run EJB 3.1 or container managed JPA applications. You will need a full EE5/EE6 compliant server like WebLogic, WebSphere, JBoss, GlassFish V3 or even JEUS 6/7 (most of which by the way run the catalina based Tomcat as their Web container).

That is exactly the point...
You don't need all the stuff mentioned to happily-easily-efficiently deploy a Roo web app.


Thank you

Yes,
Good point, if Marc does not need ORM or other non-Web container API's in JEE5/6 then a simple web container will work very well - Spring tc would be one of them.
Try the following if you would like to run application managed JPA apps using an SE bootstrap (outside of any container support).

Hello Michael,

A "simple web container" with the right stack on could do amazing things...
