QsampleBean

public QsampleBean()

Method Detail

ejbActivate

public void ejbActivate()

This method is required by the EJB Specification, but is not used by this example.

Specified by:

ejbActivate in interface javax.ejb.SessionBean

ejbCreate

public void ejbCreate()
               throws javax.ejb.CreateException

This method corresponds to the create method in the home interface "QsampleHome.java". The parameter sets of the two methods are identical. When the client calls QsampleHome.create(), the container allocates an instance of the EJBean and calls ejbCreate().

Throws:

javax.ejb.CreateException - if there is a problem creating the bean

ejbPassivate

public void ejbPassivate()

This method is required by the EJB Specification, but is not used by this example.

Specified by:

ejbPassivate in interface javax.ejb.SessionBean

ejbRemove

public void ejbRemove()

This method is required by the EJB Specification, but is not used by this example.

Specified by:

ejbRemove in interface javax.ejb.SessionBean

qtoupper

public java.lang.String qtoupper(java.lang.String toConvert)
                          throws weblogic.wtc.jatmi.TPException

This is the classic STRING qsample method, which takes the string argument, and converts it to all upper case. This implementation will get the TuxedoConnectionFactory from JNDI, and use it to get a Tuxedo object, which can then be used to do the actual tpcall. Of course, we must first convert the java String object to the TypedBuffer TypedString object.

Parameters:

toConvert - A string to be converted (not null)

Returns:

the above string, converted to upper case

setSessionContext

public void setSessionContext(javax.ejb.SessionContext ctx)

Sets the session context.

Specified by:

setSessionContext in interface javax.ejb.SessionBean

Parameters:

ctx - SessionContext Context for session
