Hello!
I have a sample axis2 client where everything i do is invoking a web
service, the problem is that the third time i invoke such webservice it
always throws a timeout exception. I guess this has to do with some
connection limit or something but after checking axis2.xml i was not able to
find out how to solve the issue.
I guess there is a way to tell the axis2 server to keep alive the connection
or close it after its been used. I am no expert here, but it looks like a
connection pooling issue to me.
Thanks in advance!
Here is the code:
public class Axis2Client {
/**
* @param args
*/
public static void main(String[] args) {
Object[] datosUsuario;
String user = "user";
String pass = "pass";
try{
//first invocation
datosUsuario = invokeWebService("
http://localhost:8180/axis2/services/LoginService";, "login", new Object[]
{user, pass},new Class[] { Long.class, String.class, String.class,
String.class});
for(int i = 0; i < datosUsuario.length; i++)
System.out.println(i + " -> " + datosUsuario[i]);
//second invocation
datosUsuario = invokeWebService("
http://localhost:8180/axis2/services/LoginService";, "login", new Object[]
{user, pass},new Class[] { Long.class, String.class, String.class,
String.class});
for(int i = 0; i < datosUsuario.length; i++)
System.out.println(i + " -> " + datosUsuario[i]);
//third invocation
datosUsuario = invokeWebService("
http://localhost:8180/axis2/services/LoginService";, "login", new Object[]
{user, pass},new Class[] { Long.class, String.class, String.class,
String.class});
for(int i = 0; i < datosUsuario.length; i++)
System.out.println(i + " -> " + datosUsuario[i]);
}
catch(Exception e){
e.printStackTrace();
}
}
public static Object[] invokeWebService(String endPoint, String op,
Object[] opArgs, Class[] returnTypes) throws AxisFault{
RPCServiceClient serviceClient;
Options options;
EndpointReference targetEPR;
QName opQName;
Object[] response = new Object[]{};
//inicializo el cliente
serviceClient = new RPCServiceClient();
options = serviceClient.getOptions();
//establezcp el endpoint
targetEPR = new EndpointReference(endPoint);
options.setTo(targetEPR);
//establezco la operacion
opQName = new QName("
http://services.spring.webservices.dietaclub.akyasociados.com.ar";, op);
//invoco el web service utilizando los parametros y los tipos que
espero que me sean devueltos
try{
response = serviceClient.invokeBlocking(opQName, opArgs,
returnTypes);
}
catch(AxisFault e){
e.printStackTrace();
throw e;
}
catch(Exception e){
e.printStackTrace();
}
return response;
}
}
