Axis-based custom object serialization

Recently, because the company used Web Services technology for Enterprise Application Integration (EAI)-related projects, the use of axis in response to technical staff cannot pass user-defined objects.

The error message is as follows:

Web services have been around for more than four years. Basically, Web Services is just a concept. With questions, I decided to give it a try. What is going on?
Finally, after more than two hours of testing, the problem was finally solved. The solution is as follows:

1. register the serialization/deserializer of custom objects on the axis server.
It is primarily to modify the WEB-INF/server-config.wsdd files under the axis installation directory.

<service name="SimpleObjectService" provider="java:RPC">  <parameter name="allowedMethods" value="*"/>  <parameter name="className" value="com.whcyit.axis.SimpleObjectService"/>  <beanMapping languageSpecificType="java:com.whcyit.axis.SimpleObject" qname="ns:SimpleObject" xmlns:ns="urn:BeanService"/></service>

Pay attention to the definition of service/beanmapping. In languagespecifictype, the class is defined. QNAME defines the class name.

2. register the serialization/deserialization tool of the custom object on the axis client.

The core code is as follows:

// Create a call object
Service = new service ();
Call call = NULL;
Call = (CALL) service. createcall ();
// Register the serialization type of simpleobject
QNAME Qn = new QNAME ("urn: beanservice", "simpleobject ");
Call. registertypemapping (simpleobject. Class, qN, new beanserializerfactory (simpleobject. Class, qN), new beandeserializerfactory (simpleobject. Class, qN ));

Sample Code:

// Simpleobject. Java

// The object passed by the web service object
Package com. whcyit. axis;
Import java. Io. serializable;
Public class simpleobject implements serializable {
/****/
Private Static final long serialversionuid =-6414428095965735488l;
Private int I = 0;
Private float F = 0.0f;
Private string STR = "";
Public simpleobject (){}
Public float getfloat () {return F ;}
Public void setfloat (float f) {This. f = f ;}
Public int getint () {return I ;}
Public void setint (int I) {this. I = I ;}
Public String getstring () {return STR ;}
Public void setstring (string Str) {This. Str = STR ;}}

// Simpleobjectservice. Java

// Service Program

package com.whcyit.axis;
public class SimpleObjectService {   
public String sayHello(String name) {    
return "Hello " + name +"!";    }        
public String getString(SimpleObject obj) {    
System.out.println("SimpleObjectService getString invoked!");    return "return by serviced:"+obj.getString();    }        
public SimpleObject createSimpleObject(int i,float f,String str) {    System.out.println("SimpleObjectService createSimpleObject invoked!");    
SimpleObject so = new SimpleObject();    
so.setInt(i);    
so.setFloat(f);    
so.setString(str);    
return so;        } }
