SOAP Client

[sathish_2111]

Hi,

I have SOAP server running. I need to write a SOAP client for the server. Can you please suggest plugin in eclipse or give me the URL related to this?

can you please provide me it you have any sample SOAP Client code?

My SOAP client should use complex objects as parmeter/arguments for the SOAP function which is exposed in the SOAP server.

Thanks in advance.

I have used a SOAP Client using apache axis client.

/* only code --- take care of the package and filename*/

package mypackage1;

import java.util.Iterator;
import java.util.Vector;

import javax.xml.namespace.QName;
import javax.xml.soap.SOAPElement;

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.message.MessageElement;
import org.apache.axis.message.SOAPBodyElement;
import org.apache.axis.soap.*;

public class HdsRulebaseStub
{
public static int save_employee(String grade, String location)
{
int save_employee =5;
try
{
HdsRulebaseStub stub = new HdsRulebaseStub();
// Add your own code here.
SOAPFactoryImpl fact=new SOAPFactoryImpl();
SOAPElement assessRequest =fact.createElement("assess-request","ns0","<GIve here Qname--- but optional --if not giving remove ns0>");
SOAPElement config =assessRequest.addChildElement("config");
config.addChildElement("show-events").addTextNode("show-events").setValue("true");
SOAPElement sessionData = assessRequest.addChildElement("session-data");
SOAPElement listEntity = sessionData.addChildElement("list-entity");
listEntity.setAttribute("entity-type","global");
SOAPElement globalEntity = listEntity.addChildElement("entity");
globalEntity.setAttribute("id","global");
SOAPElement attroutcome = globalEntity.addChildElement("attribute-outcome");
attroutcome.setAttribute("id","not_save");
attroutcome.setAttribute("outcome-style","attribute-only");
attroutcome.setAttribute("screen-if-unknown","false");
SOAPElement entityAttrib1 = globalEntity.addChildElement("attribute");
entityAttrib1.setAttribute("id","grade");
SOAPElement gradevalue = entityAttrib1.addChildElement("text-val");
gradevalue.setValue(grade);
SOAPElement entityAttrib2 = globalEntity.addChildElement("attribute");
entityAttrib2.setAttribute("id","location");
SOAPElement locationValue = entityAttrib2.addChildElement("text-val");
locationValue.setValue(location);
//System.out.println(assessRequest);

SOAPBodyElement params[]=new SOAPBodyElement[1];
params[0] = new SOAPBodyElement(assessRequest);
//System.out.println(params[0]);
Service serv = new Service();
QName qname = new QName("<Give here Qname>","ns0");
Call call = (Call)serv.createCall(qname);
call.setTargetEndpointAddress("<give here endpoint address");
call.setProperty(Call.SOAPACTION_USE_PROPERTY, Boolean.TRUE);
call.setProperty(Call.SOAPACTION_URI_PROPERTY, "<Give here SOAP action URI>");
call.setProperty(Call.OPERATION_STYLE_PROPERTY, "literal");
call.setOperationName("Assess");
Vector res = (Vector)call.invoke(params);
//System.out.println(res);
}
catch(Exception ex)
{
ex.printStackTrace();
}
}

I am using above soap client code for java. Same code is working on Windows and same code is not working on Linux. Client gets hang while receiving response.

Please help me out.
