Problem with a deployed service

[Luis Rodrigo]

Hi all.

I have deployed a test service, which just executes a command in the server:

Runtime rt = Runtime.getRuntime();
String[] cmd = {"cmd.exe","/c","C:\\winnt\\system32\\xcopy.exe","c:\a.txt","c:\\logs"};
Process proc = rt.exec(cmd);

and then returns a fixed string:

return "This is the web service running";


In the client I'm using a method to call the service, which is:

public static String stringCall(String endPoint, String serviceGroup,String serviceName, String[] parameterNames, String[] parameters){
String result=null;
try{

Service service = new Service();
Call call = (Call)service.createCall();

call.setTargetEndpointAddress(new java.net.URL(endPoint));
call.setOperationName(new javax.xml.namespace.QName(serviceGroup,serviceName));
for(int i=0;i<parameters.length;i++){
call.addParameter(parameterNames[i], XMLType.XSD_STRING,ParameterMode.IN);
}
call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);
System.out.println("Just before calling the service");
result=(String)call.invoke(parameters);
System.out.println("Service called");
}catch(Exception ex){
ex.printStackTrace();
}
System.out.println(result);
return result;
}


When I try to access the service, the following happens. The service is perfectly reached, and the xcopy command is executed (I get a copy of the a.txt in the logs file). In the client window I can see the "Just before calling the service" message, but in a moment between the

return "This is the web service running";

line in the service and the

result=(String)call.invoke(parameters);

line in the client, I get the following exception:

I have granted Tomcat full permissions. If I do not try to execute the xcopy, and just return the string, the service works fine, so I guess there is some problem in the fact of executing commands in a service. Any clues/ideas/documentation/similar experiences would be really welcome, as I am in a hurry, and this does not seem very reasonable.

Thank you very much in advance.

Luis.
