Basically a web service call is implemented by executing one of the above methods from the JITL Java class, e.g.:
- var response = com.sos.jitl.restclient.JobSchedulerRestClient.executeRestService( "http://localhost:4445/jobscheduler/agent/api/" );
- var response = com.sos.jitl.restclient.JobSchedulerRestClient.executeRestServiceCommand( "get", "http://localhost:4445/jobscheduler/agent/api/" );

The web service returns a serialized JSON Object:

The result object returned by the web service can be converted to a JavaScript JSON object by use of the eval() function:
- eval ( "var jsonObject = " + response + ";" );

Properties of the JSON object can be accessed within the object hierarchy provided by the web service result object like this:

see example for jsonObject.system.hostname from the JobScheduler Agent REST web service below:

function spooler_process() { 
    var response = com.sos.jitl.restclient.JobSchedulerRestClient.executeRestService( "http://localhost:4445/jobscheduler/agent/api/" );
    if (response) {
        eval ( "var jsonObject = " + response + ";" ); 
        spooler_log.info( jsonObject.totalTaskCount + " tasks executed on Agent [" + rest_service + "]: " + jsonObject.system.hostname );
    } else {
        spooler_log.error( "no response from REST web service at: " + rest_service );
    } 
 
    return false;
}

The web service returns an XML document:

The result can be parsed using the SOSXMLXPath Java class.

see example below

function spooler_process() { 
  var response = com.sos.jitl.restclient.JobSchedulerRestClient.executeRestService( "http://www.thomas-bayer.com/sqlrest/CUSTOMER/18/" );
  spooler_log.info( response );

  var xmlDOM = new Packages.sos.xml.SOSXMLXPath( new java.lang.StringBuffer( response ) );
  spooler_log.info( "Firstname is " + xmlDOM.selectSingleNodeValue( "//CUSTOMER/FIRSTNAME" ));
 
  return false;
}
