Java EE (Java Enterprise Edition) General Discussion

First of all please forgive me as my question may be a newbie question. I am very new to these parsers and really has no clue at all on how they actually work. Now i need some explanations and some help. First, i will like to know where can i download JAXP and which version should i use.

Next, lets say now i have a XML document, i will like to link it to a servlet in a webserver (i am using Apache Tomcat 4.0) and then to the MIDP (The MIDP i already establised a link to the servlet). Now, i would like to know are my steps correct? And also i would like to know in detail, how do i use the JAXP to link the XML document with my servlet.

Another question is, when i link my MIDP to the servlet, i found out that it runs with a parser named kxml, what does this kxml do? Since i think it support the SAX, is this a parser that can also use to parse the xml document to the servlet?

Thanks in advance
