Class ShellWS

java.lang.Object
  cgl.hpsearch.shell.ShellWS

public class ShellWS

extends Object

ShellWS listens for requests. When a request arrives it runs the request thru the shell. The request is usually a URI of the script to be executed but optionally can also include the actual script.

 
 // Sample Script 
 w = new WSDL("http://localhost:28080/ShellWS?wsdl");
 a = w
 		.invoke(
 				"execute",
 				"a = 5; RETURN_VALUE=\"http://danube.ucs.indiana.edu:6011/deltaP.xyz\"",
 				"");
