Hello together

how can i define a simple Value (String, Integer, Char, Short etc.) in the JNDI Tree. But the Value shall not be packaged in an EAR/WAR/EJB-jar. The Server Administrator shall be responsible for that value, and he must not change values in the Deployment-Package.

In other Words i need somthing like this:
In the EJB:

Context ctx=new InitialContext();
String cfg=(String)ctx.lookup("java:comp/env/MyConfigKey");

In ejb-jar.xml:

<resource-env-ref>
 <description>Admin, give me a String here please</description>
 <resource-env-ref-name>MyConfigKey</resource-env-ref-name>
 <resource-env-ref-type>java.lang.String</resource-env-ref-type>
</resource-env-ref>

And the rest shall be only somewhere in the Server-Config, but not in the EAR, because the Value is only known by the Server-Admin.

In Tomcat the Server-Admin can simply place a Element within a Element in the central server.xml-Config-File to propagate such simple values to the Application.

THX for helping me.
