Filling Java Vector using XML Config file

[homi]

Hi All,

I am writing a Java code that uses a XML Config file to configure
itself. Sample of the XML file has shown below. I want to have a peace
of java code to reads that config file and import all the data to a
class structure that I have designed before. In this case I will have
a class name AppGroup and the whole config file will be stored in
array of AppGroup objects. What is the best was of doing such a thing.
I’ve already looked at Castor but seem to complicate to me.
Thanks in advance for your help.


<?xml version="1.0"?>

<FConfig>
<ExtraConf>
<Name>TEST</Name>
<Timeout>100</Timeout>
</ExtraConf>
<AppGroup>
<Other>
<AppName>BILL5</AppName>
<FileSequenceIn>aaabbb</FileSequenceIn>
<TransferAlarm>transAlarmCall</TransferAlarm>
</Other>
<TransConf>
<Direction>INPUT</Direction>
<SourceDir>/client/home/ttt</SourceDir>
<FilePattern>aaavvv</FilePattern>
<TargetDir>/home/rrr</TargetDir>
<StateFile>auditState</StateFile>
</TransConf>
<TransConf>
<Direction>OUTPUT</Direction>
<SourceDir>/client/home/ggg</SourceDir>
<FilePattern>aaaeee</FilePattern>
<TargetDir>/home/yyy</TargetDir>
<StateFile>auditState2</StateFile>
</TransConf>
</AppGroup>
<AppGroup>
………………………..
</AppGroup>



Thanks,

Homer

A simple SAX parser could do it, if you have no need for updates and
such over time. Look into JAXP and the SAX API for details. You will
have to actually write some code to respond to elements of the config
file by setting the appropriate values in your own objects.

Have a look at http://jakarta.apache.org/commons/digester. I believe it was
written to process the Struts config file, so should suit your purposes, and
is fairly simple to use.

You could simply use a SAX parser to do it. Reading XML files using SAX
is easy, and there are a lot of tutorials on the net that show how to do
it. That would be my suggestion anyway

java.beans.XMLEncoder and java.beans.XMLDecoder. Will serialize a
vector straight off without you having to write any code IF the
objects in the vector have:
1. A default public constructor
2. public accessor methods for the object properties you want to
serialize OR the properties are public

No need to parse anything or load up an XML parser. It works much like
ObjectInputStream and ObjectOutputStream, except what you get is XML.
