java - Having trouble generating WebService artifacts -

i'm having trouble generating message , response artifacts web service. meet error in cmd when try:

c:\users\kingmarkmcc\workspace\webservicejx>wsgen -cp -keep . webserviceimp option "-classpath" requires argument

here webserviceinterface:

package cacheserver;  import javax.jws.webmethod; import javax.jws.webservice; import javax.jws.soap.soapbinding; import javax.jws.soap.soapbinding.style;  @webservice @soapbinding(style= style.document) public interface webserviceinterface {      @webmethod object get(object k);     @webmethod void put(object k, object v);     @webmethod void remove(object k);     @webmethod void flush();     @webmethod int size(); } 

and below implementation of webservice package cacheserver;

import java.util.linkedhashmap; import java.util.map;  import javax.jws.webservice;   @webservice(endpointinterface = "cacheserver.webserviceinterface")  public class webserviceimp implements webserviceinterface{  cachedatastruct cache;  webserviceimp(int i){     cache = new cachedatastruct(i); }  //getting cache @override public object get(object k){     system.out.println("get requested");     return getter(k); } private object getter(object k){     return cache.get(k); }  //putting cache @override public void put(object k, object v){     system.out.println("put requested");     putter(k,v); } private void putter(object k, object v){     cache.put(k, v); }  //removing cache @override public void remove(object k){     system.out.println("remove requested");     remover(k); } private void remover(object k){     cache.remove(k); }  //getting size of cache @override public int size(){     system.out.println("size requested");     return sizer(); } private int sizer(){     return cache.size(); }  //flushing cache @override public void flush(){     system.out.println("flush requested");     flusher(); } private void flusher(){     cache.flush(); }  class cachedatastruct extends linkedhashmap<object,object>{      private static final long serialversionuid = -8892618408950826874l;     public final int cachesize;     private final static float loadfactor =0.75f;      protected boolean removeeldestentry(map.entry<object, object> eldest) {         return size() > cachesize;     }      public cachedatastruct(int cachesize){         super(cachesize,loadfactor,true);         this.cachesize=cachesize;        }      void flush(){         clear();         system.out.println("cache has been cleared.");     } } } 

any generating artifacts appreciated!

after analysis, have picked first challenge here lies within service implementation bean (sib) webserviceimp. sib using invalid constructor : package access contructor, , expose service need add public no-arg constructor.

as defined jsr 181, class annotated javax.jws.webservice must have default public constructor. sib class must top level class or static inner class.

example of sib constructors:

    public webserviceimp() {}     public webserviceimp(int i) {         cache = new cachedatastruct(i);     } 

after above changes , after compiling(javac cacheserver/*.java), can run wsgen command or run below command (while in src folder):

     wsgen -cp "." -wsdl cacheserver.webserviceimp 

also find way of passing argument rather using constructor in sib, maybe delegate pojo instantiation of object requiring arg constructor.
