Method Detail

makeNewServiceObject

protected java.lang.Object makeNewServiceObject(MessageContext msgContext,
                                                java.lang.String clsName)
                                         throws java.lang.Exception

Return a object which implements the service.

Overrides:

makeNewServiceObject in class JavaProvider

Parameters:

msgContext - the message context

clsName - The JNDI name of the EJB home class

Returns:

an object that implements the service

java.lang.Exception

getServiceClassNameOptionName

protected java.lang.String getServiceClassNameOptionName()

Return the option in the configuration that contains the service class name. In the EJB case, it is the JNDI name of the bean.

Overrides:

getServiceClassNameOptionName in class JavaProvider

getStrOption

protected java.lang.String getStrOption(java.lang.String optionName,
                                        Handler service)

Get a String option by looking first in the service options, and then at the Handler's options. This allows defaults to be specified at the provider level, and then overriden for particular services.

Parameters:

optionName - the option to retrieve

Returns:

String the value of the option or null if not found in either scope

getServiceClass

protected java.lang.Class getServiceClass(java.lang.String beanJndiName,
                                          SOAPService service,
                                          MessageContext msgContext)
                                   throws AxisFault

Get the class description for the EJB Remote or Local Interface, which is what we are interested in exposing to the world (i.e. in WSDL).

Overrides:

getServiceClass in class JavaProvider

Parameters:

msgContext - the message context (can be null)

beanJndiName - the JNDI name of the EJB

Returns:

the class info of the EJB remote or local interface
