Please ignore this question, I have figured out the reason why I got that error.
I accidentally introduced defects to the deploy file when I do the cut-and-paste, so the deployment did not actually deploy well.

I was following the instruction presented by an article written at 01 Jan 2003(is this article a bit out-of-date? Given the progress of Axis) -- http://www-128.ibm.com/developerworks/webservices/library/ws-eight/#code 2 And I was trying the "EightBall" example presented in the article, hoping to get a sense of deploying a web service via Axis. Basically, the "EightBall" service is encapsulated in this java code: --------8<------------------------------- import java.util.Random; import java.lang.Double; import java.util.Date; public class EightBall { static String answers[] = {"Yes.", "Outlook not so good.", // The other 17 answers were // removed for brevity. "Don't count on it."}; public static String getAnswer() { return askQuestion(""); } public static String askQuestion String question) { java.util.Random r = new Random (new Date().getTime()); java.lang.Double d = new Double ((r.nextDouble()*20)-1); return new String(answers[d.intValue()]); } public static void main(String args[]) { System.out.println(getAnswer()); } } --------8<------------------------------- I "javac" this java file and copied the EightBallclass file into the ...\tomcat_direcory\webapps\axis\WEB-INF\classes. Then I ran " java org.apache.axis.client.AdminClient DeployEightBall.wsdd" on the DeployEightBall.wsdd file (see below): --------8<------------------------------- <deployment xmlns= "http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/ wsdd/providers/java"> <service name="urn:EightBall" provider="java:RPC"> <parameter name="className" value="EightBall"/> <parameter name="allowedMethods" value="getAnswer askQuestion"/> </service> </deployment> --------8<------------------------------- So far so good. Then I tried to compile and then ran the EightBallClient1 code(see below): --------8<------------------------------- import javax.xml.namespace.QName; import org.apache.axis.client.Call; import org.apache.axis.client.Service; import org.apache.axis.encoding.XMLType; import org.apache.axis.utils.Options; public class EightBallClient1 { public static void main(String [] args) throws Exception { Service service = new Service(); Call call = (Call) service.createCall(); call.setTargetEndpointAddress(new java.net.URL("http://localhost:8080/axis/servlet/AxisServlet")); call.setOperationName(new QName("urn:EightBall", "getAnswer")); try { System.out.println(call.invoke(new Object[] { })); } catch (java.rmi.RemoteException re) { System.out.println("Error - " + re); } } } --------8<------------------------------- This is the place where I got the error: The AXIS engine could not find a target service to invoke! targetService is nul Any idea? I also restarted the Tomcat, and that did not help. I use WinXP-Pro, Tomcat5.5, Axis1.2, JRE/JDK1.5. Thanks in advance, Don
