Re: Generating XML
Thank you both for your assistance. I will attempt to use the XStream library first, but the XML is not intended to to be parsed and objects re-built from it; rather the information will be used by another system. Thus, it depends how much I can customise the XStream output to suit the desired XML format. Karim, upon investigating the JAXB framework I discovered that this is the standard practise in the company I work for(student internship, hence why I was unaware) but as I have stated the simplicity of the objects and resulting XML may suit a simpler method. I had never considered manipulating the toString methods to my advantage, so if XStream does not suit then this is the path I will take.

Re: Generating XML
Hi Gary,
I understand that you want to do. From a java object, you want to produce
XML representation.
Ok, you have many framewoks that do this for you.
The 2 solutions i propose to you :
1) Use a standard way ( good practice and a framework support )
Let see JAXB API on Oracle web site because it's a standard way ( JSR
recommendation if i remember )
http://www.oracle.com/technetwork/articles/javase/index-140168.html.
This operation is called "Marshaling" e.g transforming a java object in xml.
With JAXB you can fine tune the operation.
Download JAXB and its javadoc, set your Eclipse project to add relative
*.jar and javadoc. Then code
2) If you feel that it's a heavy for what you want to do, just override the
toString() method of your java class, in order to produce xml. Here's a very
simple exemple :
class Personn
{
private String firstName, lastName;
.../... constructor(s), getters, setters, methods omitted .../
@override
public string toString()
{
// you can get class fields using introspection if you want to automate the
process
return "" + firstName + "" + "" + lastName
+ "";
}
}
I hope it helps.
Regards.

Re: Generating XML
Hi Darth, Use the Xstream library,http://xstream.codehaus.org/ its a library that serialises objects to xml and back from xml. use the toXML method and pass it the object.
