I have posted some information which might be helpful http://www.ajinkyaparakh.com/2012/01/changesimprovements-added-to-oracle.html.
All the very best

Thank you Walter and Paul

First of all thank you all for your help (I hardly posted anything here but I am a regular visitor of coderanch). Coderanch really helped me a lot whenever my mind got flooded with questions/confusions.
To get good score in OCPJP (Its my personal opinion)
1. Decide a timeline (Otherwise you will spend months in preparation)
2. Stick to K&B and get good grip of basics
3. Do some mock tests (Do not bother about score)
4. Give a second look to K&B which will help you to identify area which need improvement.
5. In between try tons of mad,messy,nonsense code it will really help you a lot.
6. And keep visiting Coderanch whenever you are free
Hope it will help you. All the very best !

PS: Please correct me if I am making any wrong assumption

I created my web service using Eclipse and Apache axis (Using this link http://www.softwareagility.gr/index.php?q=node/21). When I tested it on my local machine with Eclipse and Apchache tomcat it worked fine.
Then I deployed my web service on another machine,using files generated by eclipse. I copied the folder created under WebContent\WEB-INF\services\AutocompleteService to Jboss's server\default\deploy\i2b2.war\WEB-INF\services\AutocompleteService
When I tried to access my service it gives me following exception.
SEVERE: org.apache.axis2.AxisFault: Required element null defined in the schema can not be found in the request".

Here is my small web service (excluding biz logic)

public class AutocompleteService { public OMElement getCodes(OMElement input) { String query = input.getText(); OMFactory fac = OMAbstractFactory.getOMFactory(); OMNamespace omNs = fac.createOMNamespace("", ""); OMElement codes = fac.createOMElement("codes", omNs); // some biz logic while (SOME_CONDITION) { OMElement code = fac.createOMElement("code", null, codes); OMAttribute value = fac.createOMAttribute("value", null, tempStr); code.addAttribute(value); } return codes; } }
Am I missing something ?

Thanks David. I have added the code tag. :)
