Stating the WSO2 internship

In the first week we are asked to get familiar with the technologies that we will find in the future. These technologies are relevant to anyone who is in this filed (don't have to work in WSO2). Below I have provided what I went through the first week with the references that they use.(Thank goes to Selvaratnam Uthaiyashankar for providing these materials for us)

XML

=====

1. What is XML? -

* http://www.ibm.com/developerworks/edu/x-dw-xmlintro-i.html?S_TACT=105AGX06&S_CMP=HP

(Introduction to XML developerWorks, Doug Tidwell

(dtidwell@us.ibm.com), XML Evangelist, IBM　). It covers pretty much

everything. Do not worry about DTD, just XML Schema would do.

* http://www.ibm.com/developerworks/xml/newto/

* http://www.xml.com/lpt/a/316

2. XML Parsing, DOM, SAX and Pull - Learn about DOM, and SAX, pull

parsing you can learn later.

* SAX/DOM -http://www.ibm.com/developerworks/xml/library/x-jaxp/

* SAX - http://www.ibm.com/developerworks/xml/library/x-saxapi/

* Validation -

http://www.ibm.com/developerworks/xml/library/x-jaxpval.html?S_TACT=105AGX06&S_CMP=EDU

* StAX'ing up XML, Part 1: An introduction to Streaming API

for XML (StAX) -

http://www.ibm.com/developerworks/xml/library/x-stax1.html - there are

three articles in the StAX'ing up XML, read them later. We do not need

Stax initially for our work.

3. XML Schema - http://www.w3schools.com/Schema/default.asp

4. XML Beans -

Learn about Axis2 as much as possible. Follow the

Axis2 user guide A to Z,
