Weblogic - deploying of the new application causes the change of the datasource config

Question

Hi there,
The description of the issue is:
I have weblogic domain and some application deployed on it.
The config.xml for the domain contains following:
  <jdbc-system-resource>
    <name>Pool</name>
    <target>myserver</target>
    <deployment-order>1</deployment-order>
    <descriptor-file-name>Pool-jdbc.xml</descriptor-file-name>
  </jdbc-system-resource>
  <jdbc-system-resource>
    <name>JNDI</name>
    <target>myserver</target>
    <deployment-order>4</deployment-order>
    <descriptor-file-name>JNDI-jdbc.xml</descriptor-file-name>
  </jdbc-system-resource>
When I tried to deploy/undeploy another application (pretty much simple hello world from netbeans) on the same domain, I found that this part of config changes to:
  <jdbc-system-resource>
    <name>Pool</name>
    <target>myserver</target>
    <deployment-order>1</deployment-order>
    <descriptor-file-name>jdbc/Pool-jdbc.xml</descriptor-file-name>
  </jdbc-system-resource>
  <jdbc-system-resource>
    <name>JNDI</name>
    <target>myserver</target>
    <deployment-order>4</deployment-order>
    <descriptor-file-name>jdbc/JNDI-jdbc.xml</descriptor-file-name>
  </jdbc-system-resource>
So the path to the files changes by adding jdbc/ in the beginning.
And then first application fails to start as the path to datasource config has been changed therefore application cannot connect to the database.
Can anyone tell me why is this happening and how to avoid that? Is there any other configs, which might be affected by deploying another application?
Thank you,

Hi Viktor,
As far as I know, the default path for JDBC datasources XML files is ${DOMAIN_HOME}/config/jdbc/, and paths to JDBC datasources in config.xml are added like this "jdbc/FILE.xml", so I think it's a normal behavior.
Have you relocated the datasources XML files from thier default location, or have you created them manually directly under ${DOMAIN_HOME}/config directory..?
