Using BeanSerializer in standalone applications

[sol myr <so...@yahoo.com>]

Hi,
   
  I'm trying to use Axis BeanSerializer in a stand-alone application (converting between java objects & xml).
  Example (assuming you have a "Customer" bean):
       Customer cust=new Customer("john", "ibm"); 
       BeanSerializer ser=new BeanSerializer(Customer.class, null);
     SerializationContext ctx=new SerializationContext(new FileWriter("cust.xml"));
     ser.serialize(someQName, null, cust, ctx);
   
  My question: 
  Can I *customize* this BeanSerializer, so as to control the XML output ?
  For example:
  - Configure xml namespaces
  - Configure xml tag-names 
 (e.g. java field "Customer.surName" should be mapped to xml "< last-name >" ). 
   
  Does axis allow such customization (from a stand-alone app) ? Is it somewhere on the API ? Or can you configure it from a file (similar to wsdd) ?
   
  Thanx.

First of all I’m a bit curious why you want to use axis and bean
serialization in a stand alone application. There are far better
frameworks than Axis for converting beans to XML. 

For example, check out JAXB and reference implementations
http://java.sun.com/webservices/jaxb/index.jsp
Castor can also be used.

If you *really* want to do this, you should check out the static typedesc
data, in the generated Axis xlasses. 
The typedescriptions define how the fields of the object is mapped to XML
(and back I believe) 

Example type description section follows. Notice the
elemField.setFieldName("companyName"); This is the “bean property” of the
local
object, and a method “getcompanyName()” is required in the bean. 

The following typedescription is for an entity called “Company” with two
members “companyName” and “companyAddress”

private static org.apache.axis.description.TypeDesc typeDesc =
        new org.apache.axis.description.TypeDesc(SetCompanyType.class,
true);

    static {
        typeDesc.setXmlType(new
javax.xml.namespace.QName("http://schemas.company.com", "Company"));
        org.apache.axis.description.ElementDesc elemField = new
org.apache.axis.description.ElementDesc();
        elemField.setFieldName("companyName");
        elemField.setXmlName(new
javax.xml.namespace.QName("http://schemas.company.com", "companyName"));
        elemField.setXmlType(new
javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"));
        elemField.setNillable(false);
        typeDesc.addFieldDesc(elemField);

        elemField = new org.apache.axis.description.ElementDesc();
        elemField.setFieldName("companyAddress");
        elemField.setXmlName(new
javax.xml.namespace.QName("http://schemas.company.com/", "companyAddress"));
        elemField.setXmlType(new
javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"));
        elemField.setNillable(false);
        typeDesc.addFieldDesc(elemField);
    }

Hi,
 
I'm trying to use Axis BeanSerializer in a stand-alone application
(converting between java objects & xml).
Example (assuming you have a "Customer" bean):
     Customer cust=new Customer("john", "ibm"); 
     BeanSerializer ser=new BeanSerializer(Customer.class, null);
     SerializationContext ctx=new SerializationContext(new
FileWriter("cust.xml"));
     ser.serialize(someQName, null, cust, ctx);
 
My question: 
Can I *customize* this BeanSerializer, so as to control the XML output ?
For example:
- Configure xml namespaces
- Configure xml tag-names 
 (e.g. java field "Customer.surName" should be mapped to xml "< last-name >"
). 
 
Does axis allow such customization (from a stand-alone app) ? Is it
somewhere on the API ? Or can you configure it from a file (similar to wsdd)
?
 
Thanx.
