How to change JRE version of JWS

[kiran mahavir]

Hello all,
I am using java web server 2.0 for my project.But it does not support methods like Double.parseDouble(),classes HashMaps,Sets etc which are available from JDK1.2 onwards.I came to know that JWS uses jre 1.1.7 which does not support classes as mentioned above.I need support for those classes.
So how to go about this.
Kindly give the reply at the earliest
with regards
Kiran

There is no reason to use outdated software. Download Tomcat from http://jakarta.apache.org/tomcat/index.html and set its JAVA_HOME environment variable to your JDK1.3 root directory.
