Method Detail

makeNewServiceObject

protected Object makeNewServiceObject(MessageContext msgContext,
                                      String clsName)
                               throws 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
Throws:: Exception

getServiceClassNameOptionName

protected 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 String getStrOption(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 Class getServiceClass(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
Throws:: AxisFault

getCachedContext

protected InitialContext getCachedContext()
                                   throws NamingException

Throws:: NamingException

Throws:: AxisFault; NamingException

getEJBHome

protected Object getEJBHome(InitialContext context,
                            String beanJndiName)
