getConnectionSpecClass

protected Class<? extends javax.resource.cci.ConnectionSpec> getConnectionSpecClass(String connectionSpecClass)
                                                                             throws ClassNotFoundException,
                                                                                    IllegalArgumentException

Looks up and returns the specified class. First, it will try to get the class from the context class loader, if not found, it will try to get it from the current class loader.

Parameters:

connectionSpecClass - The fully qualified class name of the ConnectionSpec implementation.

Returns:

The Class object of the ConnectionSpec implementation

Throws:

ClassNotFoundException - - if the class could not be found.

IllegalArgumentException - - if the class does not implement javax.resource.cci.ConnectionSpec.

newConnectionSpecInstance

protected javax.resource.cci.ConnectionSpec newConnectionSpecInstance(Class<?> connectionSpecClass,
                                                                      Class<?>[] constructorParameterTypes,
                                                                      Object[] constructorArguments)
                                                               throws InternalHiberSapException

Creates a new instance of the specified ConnectionSpec implementation class via reflection.

Parameters:

connectionSpecClass - The class to instantiate. Must implement javax.resource.cci.ConnectionSpec.

constructorParameterTypes - The types of the constructor's parameters. Used to determine which constructor should be used.

constructorArguments - The constructor's arguments used when creating a new instance of the class. Must match the constructorParameterTypes.

Returns:

The instance of the ConnectionSpec implementation

Throws:

InternalHiberSapException - - if there the class could not be accessed or instantiated, see cause for the actual reason.
