Hi, I'm new to both Axis2 and web services and I'm having a hard time grasping all the various types of databinding that can be created (POJO, AXIOM, ADB, XMLBeans and JiBX). I have a couple of general questions about Axis2 and web services.
I need to create a service that can pass complex objects between the client and the server. Something like my modified weather example below. My questions about this are as follows: 1) In the testing I've done I noticed that it fails when there are any java.util.Vector or java.util.List objects within the object being transferred. I have seen several other posts about this but with no responses. Does anyone know why this is the case? How can I get around this? I read that using an ArrayList object will work which I did verify, but I need to be able to user List and Vectors. 2) In the following modified Weather class where I have an ArrayList called children with its set and get methods (this is from the sample.pojo.rpcclient package distributed with Axis2). When I send this weather class on a round trip to the WeatherService service calling the setWeather then the getWeather methods, then I take the returned weather class and call it's getChildren method I end up with an ArrayList of OMEElement objects rather than Weather objects as I wanted. I understand that everything is converted to XML during transport, but how do I get these elements mapped back into the Weather class? package sample.pojo.data; import java.util.ArrayList; public class Weather{ float temperature; String forecast; boolean rain; float howMuchRain; ArrayList<Weather> children=null; public Weather() { children=new ArrayList<Weather>(); } public Weather(String forecast) { children=new ArrayList<Weather>(); this.forecast=forecast; } . . . public void setChildren(ArrayList<Weather> c) { children=c; } public void addChild(Weather w) { children.add(w); } public ArrayList<Weather> getChildren() { return children; } } 3) Based on needing to transfer this kind of object what type of databinding would be best for me to use. Are there some that would work better than others, In my testing I'm using this POJO sample? But I'm thinking that I should use ADB or XMLBean. Any suggestions? 4) The client that will be accessing this service will be running within both a standalone application and a Java applet. For the sake of the Java applet I would like the client footprint to be as small as possible. Based on this requirement are there some databindings that have a smaller footprint than others? I realized that I'm not grasping all the concepts that I need to understand here, I'm not even sure I'm asking the right questions? I have been looking at the documentation and samples that come with Axis2. Are there any other good resources that I can look at that might help me out here, such as some good tutorials or FAQ's. Some more good code samples would be helpful tool. Any comments offered would be greatly appreciated. Thanks, David
