WSDL - Java problem

Question

Hi all,
I have been trying to generate a web service from a WSDL file (which, in my opinion, is the best way to create a web service when you don't already have a program). But there's some problems I run across which I can't seem to find the solution for.
My traject should be: WSDL -> Java Files -> Compiling -> Deployment, where my primary WSDL should not be changed (or just endpoint address)
I use JWSDP 1.2.
1)
When I try to replicate the helloservice, static stub example with my own WSDL file, I receive the following error:
wscompile.bat -gen:server -d build -classpath build config-wsdl.xml
error: generator error: no encoder for type "{http://www.w3.org/2001/XMLSchema}date" and Java type "java.util.Calendar"
can anyone explain what this is?
2)
I tried -import and -keep instead of -gen:server, to get my Java files. This worked and created a lot of java files and even an implementation file, where I could create my webservice. So far it looked good, but after compiling and deploying, the service does not work. The problem is that the generated classes all have changed names (first letter lowercase, instead of uppercase), resulting in a non-working application.
SEVERE: Exception sending context initialized event to listener instance of class com.sun.xml.rpc.server.http.JAXRPCContextListener
java.lang.NoClassDefFoundError: MyService/MyProtocol_myOperation_ResponseStruct
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:217)
at com.sun.xml.rpc.server.http.JAXRPCRuntimeInfoParser.loadClass(JAXRPCRuntimeInfoParser.java:150)
Where myOperation in my WSDL file is called 'MyOperation'
So now I'm stuck, can anybody help me or give me a step-by-step how to create a service

Answer 1

Here's how I do it. I hope this won't annoy other people since this will be a long code post.
1) Create the java interface: DateServiceInf.java:
package MyService;
import MyService.holders.*;
public interface DateServiceInf extends java.rmi.Remote {
     public void setDate(java.util.Date date) throws java.rmi.RemoteException;
     public void getDate(DateHolder dholder) throws java.rmi.RemoteException;
2) Create the java implementation: DateServiceImpl.java:
package MyService;
public class DateServiceImpl implements MyService.DateServiceInf{
     java.util.Date date = new java.util.Date();     //current date
     public DateServiceImpl() {
     public void getDate(MyService.holders.DateHolder dholder) throws java.rmi.RemoteException{
          dholder.setDate(date);
     public void setDate(java.util.Date date) throws java.rmi.RemoteException{
          this.date = date;
3) Create the holder class: DateHolder.java
package MyService.holders;
public class DateHolder {
     private java.util.Date date;
     public DateHolder() {
          date = null;
     public java.util.Date getDate() {
          return date;
     public void setDate(java.util.Date date) {
          this.date = date;
Compile the whole thing now.
(you can skip to step 5 below)
4) Using Apache axis to generate the wsdl file, assume the unzip axis1.1 is located at d:\axis-1_1 (windows bat file) and jdk at c:\j2sdk1.4.0: (make sure all files above are located in the proper directories (packages).
@echo off
set AXIS_HOME=d:\axis-1_1
set AXIS_LIB=%AXIS_HOME%\lib
set AXISCLASSPATH=%AXIS_LIB%\axis.jar;%AXIS_LIB%\commons-discovery.jar;%AXIS_LIB%\commons-logging.jar;%AXIS_LIB%\jaxrpc.jar;%AXIS_LIB%\saaj.jar;%AXIS_LIB%\log4j-1.2.8.jar;%AXIS_LIB%\xml-apis.jar;%AXIS_LIB%\xercesImpl.jar;%AXIS_LIB%\wsdl4j.jar
c:\j2sdk1.4.0\bin\java -cp %AXISCLASSPATH%;. org.apache.axis.wsdl.Java2WSDL -l"http://www.mycomp.com/MyService" -n "urn:MyService" -p"MyService" "urn:MyService" -o MyService.wsdl MyService.DateServiceInf
Here is the generated file using axis:

5) Generate the wsdl using the Sun's implementation. Assume that the installation is located at: C:\j2sdkee1.4
@echo off
c:\j2sdk1.4.0\bin\java -cp . org.apache.axis.wsdl.Java2WSDL -l"http://www.mycomp.com/MyService" -n "urn:MyService" -p"MyService" "urn:MyService" -o MyService.wsdl MyService.DateServiceInf
(those are 2 lines: echo and java)
You may get a warning here.
Here is the generated file from Sun:
