hi guy,
You r using a deprecated methods of SAX API. You can compile your file as like this 'javac FileName -deprecation' , Now it will compile. Even u have to use the JDK version 1.3 and above and check whether class path is set properly .

hi datatreya,
i have jsdk1.4.i tried using javac filename -deprecation but even then i am getting 3 warnings .when i try to run then i am getting an error saying NoClassDefFoundError org/sax/handlerBase not found.
can you please help.
thanks

getting an error saying NoClassDefFoundError org/sax/handlerBase not found.

If that is really the error, you are using a bad package somewhere.
org.xml.sax.HandlerBase
is the correct full name. Even though the class is deprecated I think you should be able to get it to work.

Your program runs fine. There's no runtime problem with deprecated
classes/messages. To me it looks like a simple Java 101 error with the
CLASSPATH.

Since you are using JSDK 1.4, add the JAVA_HOME\lib path to your CLASSPATH
inaddition to the '.' current directory and you should be able to run the
file, thus echoing the XML file.

BTW, you might want to pay close attention to the package names/paths.
If you make typos, you wouldn't even be able to compile.
