Body
Why are you trying to execute 'jar -cp'. This will be a separate jvm execution and hence you will not be able to directly access the resources in the jvm running the web application (this means objects spawned in the jvm's memory space by the web application). [This is answer to your question about conflict/ Please mention what application server on which your web application is running. Seeing your comment about System Administrator (though I would have mentioned this regardless of this as well). Have you ever heard of ServiceMBeans, you can try them. Your scenario is a very generalized scenario, where people need to access a particular class (better say instance of the class) running inside a JVM. You certainly need something which loads up along with the application. You can write a Service MBean to run along (inside) your web application. This would mean you are exposing action. Then you can write a java client to interact with the MBean and make call to its exposed methods. In case your application server provides authentication for accessing MBeans. Other option is JMS implementation. Setup a JMSQueue, whose listener will execute the action interacting with the classes of web application. Obviously the listener would load along side web application. EJB implementation would allow you to load the listener via simple ejb xml or through annotations. Then you write up a separate java code which can send message commands to the JMSQueue. All application server provides the option of authentication.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
