java mapping

[former_member189441]

hi,

how can i write code in java mapping.its not seems like normal java code?

is it depends on the type of Parser which we are using?

if i go for JDOM, how can write my own code?

if i go for SAX how can write code?

if u have any docs about this plz send me

Hi,

Java mapping can be used when you have complex mapping structures.

We can do most of the times for our requirements through Graphical mapping.

When the structures are very complex to build you can go for SAX (Simple API for XML) or DOM (Document Object Model) parsers.

Message mapping internally generates DOM parser.

Java Mapping uses 2 types of parsers. DOM and SAX. DOM is easier to use with lots of classes to help you create nodes and elements, but , DOM is very processor intensive.

SAX parser is something that parses your XML one after the other, and so is not processor intensive. But, it is not exaclty easy to develop either.

If you are using SAX parser, there are 4 events. They are 1) Start of the document(startDocument)

2) start of the element(startElement)

3) end of the element(endElement)

4) end of the document(endDocument)

Also check with any java site about SAX events how it works etc.

Probably this will be useful links for u for java mapping

Hi Murali,

It is very much like normal Java code only. It takes two parameter, one as InputStream and OutputStream.Your input can be extracted using InputStream, then you can use any Parser Java SAX or DOM can transform the structure into target structure.

SAX parser is much more faster than DOM parser as it is event driven.. You can refer to the link provided in the above reply.

Thanks

There are lot of codes on the wiki that should help you with Java mapping.

The two approaches mainly are SAX and DOM parser based mappings.
