Deploying a jdev adf app on standalone weblogic issues

Question

Dear all,
Sorry for my post which is very long but i will try to give you all information.
I am currently developing a full stack ADF application (with BC4J to access the database) using Jdev 11g last release (5407)
When working in JDev, my application is running perfectly.
Now i am facing several issues regarding the deployment on a standalone weblogic.
* 1st problem: deploying from Jdev into a remote weblogic server *
If i try to deploy on a separate machine from jdeveloper directly using a server connection, then deployment failed with message in jdev console:
[04:53:47 PM] Weblogic Server Exception: weblogic.deploy.api.internal.utils.DeployerHelperException: The source 'C:\Temp\lara_abcf.ear' for the application 'Lara ABCF' could not be loaded to the server 'http://MYSERVER:7001/bea_wls_deployment_internal/DeploymentService'.
Read channel closed
[04:53:47 PM] See server logs or server console for more details.
[04:53:47 PM] weblogic.deploy.api.spi.exceptions.ServerConnectionException: [J2EE Deployment SPI:260041]Unable to upload 'D:\jdev-workspace\LaraABCF\deploy\lara_abcf.ear' to 't3://MYSERVER:7001'
[04:53:47 PM] #### Deployment incomplete. ####
[04:53:47 PM] Deployment Failed
I tried to look into weblogic logs and see nothing helping me to found the problem. Any idea?
I then tried to create a local domain on my workstaion and now deploying from JDeveloper works.
I created an EAR file from Jdev and deployedthe EAR from the weblogic web console.
From both method i was facing the same issue:
* 2nd problem: deploying an application with a datasource access into a standalone weblogic *
- Using the default configuration, i successfully deployed the application using weblogic console but the application stay on "Prepared" state in the console. Starting it from the console the application failed to start after the deployment. The error message display in the top of the web page is :
Error weblogic.common.ResourceException: java.security.PrivilegedActionException: weblogic.common.ResourceException: java.security.PrivilegedActionException: weblogic.common.ResourceException: No credential mapper entry found for password indirection user=lra_abcf for data source laraABCFConn
-I found an entry in the forum (What does this message mean? which give an hint to solve this issue:
Modify the application properties from JDev and uncheck the option: "Auto Generate and Synchronize weblogic-jdbc.xml Descriptors During Deployment", rebuild and deploy the application.
I try this method and teh application successfully starts but does not work: stacktrace in weblogic console indicates that BC4J does not work properly and i think that database connection are not up. The error Message:
javax.el.ELException: java.lang.NullPointerException

The NPE is on a line accessing a view object.
* Final question:
Is it possible to develop an application using a local database connection for BC4J in jdev and an external datasource when the application is deployed on a standalone weblogic without modifying the source code?
The real issue about this is : is there a step by step tutorial explaining how to develop a simple ADF11g application using BC and deploy it successfully on a weblogic server?
Thanks for your help

Answer 1

found a workaround:
* create a datasource on the weblogic side, mapped into the JNDI tree
* create a new configuration in the appmodule with a new datasource mapped to this jndi reference
* modify the databinding of my page to use this app module configuration
* deploy again the application and this works
but now my application does not work in jdeveloper because it seeks to a datasource in JNDI. I must revert to old settings for development en switch to these new settings to deploy on the server. Very annoying...
Thanks for you help :)
