Hi all,
I need some help on
serialization/deserialization.
I have created a web-service whose code
is given below:
package test.service ;
public class
Service
{
public Data
dataOperation()
{
return new Data()
;
}
}
Data is a simple java
bean.
The definition of Data class is given
below:
package test.service ;
import java.util.Vector
;
public class Data
{
public String
stringMember ;
public Vector vectorMember
;
public Object[]
arrayMember ;
public Data()
{
stringMember = "string"
;
vectorMember = new Vector()
;
vectorMember.addElement(
"vishal batra" ) ;
vectorMember.addElement( "satbir singh" ) ;
vectorMember.addElement( "faisal abhdullah" )
;
vectorMember.addElement( "mohammad shadab" ) ;
arrayMember = new Object[ 2 ] ;
arrayMember[ 0 ] = "first" ;
arrayMember[ 1 ] = new Long( 1234567890 )
;
}
public void
setStringMember( String stringMember )
{
this.stringMember = stringMember
;
}
public String
getStringMember()
{
return stringMember ;
}
public void setVectorMember( Vector
vectorMember )
{
this.vectorMember = vectorMember
;
}
public Vector
getVectorMember()
{
return vectorMember ;
}
public void setArrayMember( Object[] arrayMember
)
{
this.arrayMember = arrayMember
;
}
public Object[]
getArrayMember()
{
return arrayMember ;
}
}
I create the following deployment
descriptor:
<deployment
xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<service name="TestService"
provider="java:RPC">
<parameter name="className"
value="test.service.Service"/>
<parameter name="allowedMethods"
value="*"/>
</service>
</deployment>
My deployment is sucessful but when I try to
incoke the dataOperation() through client I get a exception in the soap
response complaining that a serializer not found for Data. and my client
throws an internal server exception
So I modify my deployment descriptor as
follows:
<deployment
xmlns="http://xml.apache.org/axis/wsdd/"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<service name="TestService"
provider="java:RPC">
<parameter name="className"
value="test.service.Service"/>
<parameter name="allowedMethods"
value="*"/>
<beanMapping
qname="myNS:Data"
xmlns:myNS="urn:TestService"
languageSpecificType="java:test.service.Data"/>
</service>
</deployment>
Finally i get a proper soap response which i have
given below. I have caught this soap response from org.apache.axis.utils.tcpmon tool
HTTP/1.0 200 OK

</multiRef>
</SOAP-ENV:Body>

But my client is still giving me an
