createPool

public ApplicationPool createPool(java.lang.String sName,
                                  java.lang.String sClass,
                                  java.lang.String sApplicationModule,

                           throws java.lang.Exception

Create a new Application Module pool, throws an exception if the pool is already registered. The connectInfo parameter provides the necessary settings required for creating instances of ApplicationModules that are part of the pool. You can also specify the name of the class that implements the ApplicationPool interface. This is an important setting for users that want to provide a custom implementation of the ApplicationPool interface. The default ApplicationPool implementation is in the oracle.jbo.client.ampool.ApplicationPoolImpl class.

Throws:

java.lang.Exception

                           throws java.lang.Exception

Creates a new Application Module pool, throws an exception if the pool is already registered.

This method creates an Application Module pool, based on the named AppModule Configuaraion

The application module configuration provides the necessary settings required for creating instances of Application Modules that are part of the pool. You can also specify the name of a custom application pool implementation (implements oracle.jbo.common.ApplicationPool interface). The default ApplicationPool implementation is provided in oracle.jbo.common.ampool.ApplicationPoolImpl.

Parameters:

sName - name of the pool

sPackageName - package name of the AppModule., package10, for package10.Package10Module

sConfigName - named Configuration to use

props - collection of additional properties to be passed to the application pool

Throws:

java.lang.Exception
