Hi,

add a depedency to DC tc/je/locking/api in SC ENGFACADE.

You may use DC Type J2EE / EJB or plain Java depending on your needs.

Hi Rolf!

Great, now the api are available in EJB project.

But, when I try to implement the code below in EJB business method, the compiler says me:

"No exception of type TechnicalLockException can be thrown; an exception type must be a subclass

of Throwable"

InitialContext ctx = new InitialContext();

try {

* LogicalLockingFactory lf =*

* (LogicalLockingFactory) ctx.lookup(*

* LogicalLockingFactory.JNDI_NAME);*

* LogicalLocking logicalLocking =*

* lf.createLogicalLocking("SAP/FM", "SAP Facility Management");*

} catch (NamingException ne) {

* // JNDI lookup error*

} catch (TechnicalLockException tle) {

* // the namespace is already reserved for another description*

} catch (IllegalArgumentException iae) {

* // the namespace is already reserved for another description*

}

Have a sintax error at "} catch (TechnicalLockException tle) {"

You know what's up?!
