haha reopened AXIS2-2775:
-------------------------
Thanks for your helps very much.
I have no more those failures, but i don't know why, i guess, that the
"RPCMessageReceiver" caused this, it needs always a returnvalue, so i did the
follows:
I changed the "public void MyConnction()" on the Server side to "public
Boolean MyConnection()" with "return true", and on the client side i changed
the code to:
public void MyConnection(String user, String passwd)throws RemoteException{
Options options = new Options();
RPCServiceClient serviceClient = new RPCServiceClient();
options.setTo(targetEPR);
options.setAction("urn:MyConnection");
serviceClient.setOptions(options);
options.setExceptionToBeThrownOnSOAPFault(false);
QName opSet = new QName("http://services.solver.nx.wp.com/xsd";,
"MyConnection");
Object[] response = serviceClient.invokeBlocking(opSet,new Object[]
{user,passwd},new Class[]{Boolean.class});
Boolean result =(Boolean)response[0];
if (result == false)System.out.println("no results!");
else
System.out.println("Result "+ result);
if(response[0] instanceof AxisFault)
{
throw (RemoteException)response[0];
}
}
---------------------------------------------------------------
so this time it works fine, but only local and only inside the Eclipse. If i
put the Service and the client Programm onto differente Computers, it doesn't
work any more, there occurt a Exception "AxisFault: Connection refused:
connect". How can i set the structure of the Client and the Server side? must
be a Tomcat Server on cleint side Computer installed? can you tell me please?
