Could not perform loook up operation in JBoss..need urgent help

[kala praveen]

Hello,

I am trying use a SQL Server Data Source object through JBoss server but getting so many errors.

I think I have all the required jar files in CLASSPATH.

I have copied the mssql-ds.xml to JBOSS_DIST\server\default\deploy directory and modified it in the following way:

<datasources>
<local-tx-datasource>
<jndi-name>MSSQLDS</jndi-name>
<connection-url>
jdbc:microsoft:sqlserver://172.20.37.219:1433;DatabaseName=master
</connection-url>
<driver-class>
com.microsoft.jdbc.sqlserver.SQLServerDriver
</driver-class>
<user-name>sa</user-name>
<password>welcome</password>
</local-tx-datasource>
</datasources>

I also had standardjaws.xml modified and copied to E:\jboss-3.2.4\server\default\conf directory.

while starting up the server shows the following confirmation:

14:11:00,780 INFO [MSSQLDS] Bound connection factory for resource adapter for ConnectionManager 'jboss.jca:service=LocalTxCM,name=MSSQLDS to JNDI name 'java:/MSSQLDS'

But, when I execute the following client code on the same machine, it is giveing runtime error:
**after setting the env props into HashTable ht..

Context ic=new InitialContext(ht);
DataSource ds=(DataSource)ic.lookup("java:comp/env/jdbc/MSSQLDS");

Error:

*** I have also tried the above look up statement with java:/MSSQLDS, java:/env/MSSQLDS and all the possible combinations.

It is not detecting whatever that comes after "java: "

I am really tiered with this error...Writing here with a ray of hope..plz help me.

Hi Kala,

I think you should check you deployment descriptor (ejb-jar.xml), for in order to get a DataSource from some EJB you must configure a resource reference to it. So for each bean that needs access to the DataSource, you should have something like this in your ejb-jar.xml:

<entity>
    <!-- ... -->
    <resource-ref >
        <res-ref-name>jdbc/DataSource</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
    </resource-ref>
</entity>

And in jboss.xml (just once):

<resource-managers>
  <resource-manager>
     <res-name>jdbc/DataSource</res-name>
     <res-jndi-name>java:/MSSQLDS</res-jndi-name>
  </resource-manager>
</resource-managers>

And then you lookup like this:

InitialContext ctx = ...;
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/DataSource");

I hope that's all. Best regards,
