sender soap async reliabilty

Dear All

test scenario  async sender soap in java.

try {

    1. callling async sender soap with soap url

    2.  System.out.println("XI Call Success!!!");

} catch ( exception a )

}

when  i  tried to above number 1,  message came to  PI AAE as well. and i got above number 2,

then i tried to execute my java again after PI Channel stop or PI goes down,

but still see number 2,  no any error  return to me.  also there is no message in message monitor

how to catch  connection failure  up between java calling to PI  and  PI AEX ???

is there a any good solution with PI send soap adapter for async?
