[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Re: Could not find datasource message in client JPA although

[ezanih]

Thanks for the reply, jakiran.

Ok...I've been doing a lot of reading so let me share with you and all some knowledge :-)   but my client still not working    :-(

There are 3 ways to add jndi.properties to the client app :- (1) from the Eclipse Run Configuration menu, just add this to the VM arguments:-


  | -Djava.naming.provider.url=jnp://localhost:1099
  | -Djava.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
  | 

or you can do like my BidClient.java coding above and put the properties in code

or you can just create a text file, name it jndi.properties and place it in root folder of client app. I've modified my app for this method so I can comment out all the InitialContext code additions and just put


  | InitialContext ctx = InitialContext();
  | 

Much cleaner...Ok...that is settled....

Now I've read some more and it seems JBoss needs two more configurator files at the client side, namely application-client.xml and jboss-client.xml.

I've added these 2 files :-

application-client.xml:

<?xml version="1.0" encoding="UTF-8"?>
  | 
  | <application-client xmlns="http://java.sun.com/xml/ns/j2ee"
  |           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  |           xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
  |           http://java.sun.com/xml/ns/j2ee/application-client_1_4.xsd"
  |           version="1.4">
  | 
  |   <display-name>BiddingClient</display-name>
  | 
  |   <resource-ref>
  |     	<res-ref-name>java:OracleXE1_DS</res-ref-name>
  |         <res-type>javax.sql.DataSource</res-type>
  |     	<res-auth>Container</res-auth>
  |   </resource-ref>
  | 
  | </application-client>
  | 

jboss-client.xml:


  | <jboss-client>
  |   <resource-ref>
  |     	<res-ref-name>java:OracleXE1_DS</res-ref-name>
  |     	<res-type>javax.sql.DataSource</res-type>
  |         <jndi-name>OracleXE1_DS</jndi-name>    	
  |   </resource-ref>
  | </jboss-client>
  | 


Unfortunately, still getting the same error...Unable to find data source and the jndi initial naming error, see below:
