Apache Axis: Object serialization

There may be a better way to do this but here's what I've come up with:

/**

* This is a utility class for working with Axis generated objects.

*

* @author Bob Withers bwit@pobox.com

*/

import java.io.StringWriter;

import java.lang.reflect.Method;

import javax.xml.namespace.QName;

import org.apache.axis.MessageContext;

import org.apache.axis.description.TypeDesc;

import org.apache.axis.encoding.SerializationContextImpl;

import org.apache.axis.encoding.ser.BeanSerializer;

import org.apache.axis.server.AxisServer;

import org.xml.sax.helpers.AttributesImpl;

public class AxisObjectUtil

{

/**

* Convert an Axis data object (as generated by WSDL2Java) to an XML string.

*

* @param obj The xis JavaBean object.

* @param removeNamespaces If true all namespace attributes will be removed from

*the returned XML string.

*

* @return A string containing the XML of the seriaslized Axis JavaBean object.

* @throws AxisObjectException If an error is encountered while serializing

*the Axis JavaBean.

*/

public static String serializeAxisObject(final Object obj, final boolean removeNamespaces,

final boolean prettyPrint) throws AxisObjectException

{

final StringWriter outStr = new StringWriter();

final TypeDesc typeDesc = getAxisTypeDesc(obj);

QName qname = typeDesc.getXmlType();

String lname = qname.getLocalPart();

if (lname.startsWith(">") && lname.length() > 1)

lname = lname.substring(1);

qname = removeNamespaces ? new QName(lname) : new QName(qname.getNamespaceURI(), lname);

final AxisServer server = new AxisServer();

final BeanSerializer ser = new BeanSerializer(obj.getClass(), qname, typeDesc);

final SerializationContextImpl ctx = new SerializationContextImpl(outStr, new MessageContext(server));

ctx.setSendDecl(false);

ctx.setDoMultiRefs(false);

ctx.setPretty(prettyPrint);

try

{

ser.serialize(qname, new AttributesImpl(), obj, ctx);

}

catch (final Exception e)

{

throw new AxisObjectException("Unable to serialize object " + obj.getClass().getName(), e);

}

String xml = outStr.toString();

if (removeNamespaces)

{

// remove any namespace attributes

xml = xml.replaceAll(" xmlns[:=].*?\".*?\"", "").replaceAll(" xsi:type=\".*?\"", "");

}

return(xml);

}

/**

* Return the Axis TypeDesc object for the passed Axis JavaBean.

*

* @param obj The Axis JavaBean object.

*

* @return The Axis TypeDesc for the JavaBean.

* @throws AxisObjectException If the passed object is not an Axis JavaBean.

*/

public static TypeDesc getAxisTypeDesc(final Object obj) throws AxisObjectException

{

final Class objClass = obj.getClass();

try

{

final Method methodGetTypeDesc = objClass.getMethod("getTypeDesc", new Class[] {});

final TypeDesc typeDesc = (TypeDesc) methodGetTypeDesc.invoke(obj, new Object[] {});

return(typeDesc);

}

catch (final Exception e)

{

throw new AxisObjectException("Unable to get Axis TypeDesc for " + objClass.getName(), e);

}

}

}
