Marcelo Grassi commented on XMLRPC-138:
---------------------------------------

Here is what i did:
First, i extends the StringSerializer and override the write method and passed 
the TAG parameter:

import org.apache.xmlrpc.serializer.StringSerializer;
import org.xml.sax.ContentHandler;
import org.xml.sax.SAXException;

public class StringSerializer2 extends StringSerializer {

        /* (não-Javadoc)
         * @see 
org.apache.xmlrpc.serializer.StringSerializer#write(org.xml.sax.ContentHandler, 
java.lang.Object)
         */
        public void write(ContentHandler pHandler, Object pObject)
                        throws SAXException {
                write(pHandler, STRING_TAG, pObject.toString());
        }
        
}


After that, i created a custom factory.
If the instance of the parameter is String, i use the nem Serializer that i 
override:

import org.apache.xmlrpc.common.TypeFactoryImpl;
import org.apache.xmlrpc.common.XmlRpcController;
import org.apache.xmlrpc.common.XmlRpcStreamConfig;
import org.apache.xmlrpc.serializer.TypeSerializer;
import org.xml.sax.SAXException;

public class MyTypeFactory extends TypeFactoryImpl {

        public MyTypeFactory(XmlRpcController pController) {
        super(pController);
    }
        
        public TypeSerializer getSerializer(XmlRpcStreamConfig pConfig, Object 
pObject) throws SAXException {
        if (pObject instanceof String) {
            return new StringSerializer2();
        } else {
            return super.getSerializer(pConfig, pObject);
        }
    }
}

And then, in my client class, i set the factory that i created:

client.setTypeFactory(new MyTypeFactory(client));


Now the tag <String> is always writed in xml.
I have to do that because the Service that i´m using needs to receive the Tag 
always.

Thanks for the help.

>    Affects Versions: 3.0
>         Environment: Java
>            Reporter: Marcelo Grassi
>
> There is a issue in StringSerializer.java.
> The problem is when a parameter is an array of objects.
> When a object of this array is a String, the xmlrpc does not insert the 
> <string></string> tag.
> The xmp-rpc specification says that the tag must be inserted !
> I found the method where is the problem.
>       public void write(ContentHandler pHandler, Object pObject) throws 
> SAXException {
>               write(pHandler, null, pObject.toString());
>       }
> I changed the null parameter to constant STRING_TAG and then the tag was 
> inserted well.
> Thanks.
