Hello All,
I was trying to compile a sample servlet program under the following environment
Windows NT 4 SP 5
Apache Tomcat 4.1.12
Sun JDK 1.4.0
I am getting the following error :
E:\javaprog>javac ServletTemplate.java
error: Invalid class file format in E:\Tomcat
4.1\common\lib\servlet.jar(javax/servlet/http/HttpServlet.class). wrong version: 46, expected 45
ServletTemplate.java:5: Superclass javax.servlet.http.HttpServlet of class
ServletTemplate not found.
public class ServletTemplate extends HttpServlet{
^
2 errors
I checked the CLASSPATH and JAVA_HOME variable.
The JAVA_HOME is set to the path where jdk 1.4 is installed.The CLASSPATH includes the path to servlet.jar found under TOMCAT_HOME\common\lib.
Has someone else faced a similar problem?I have seen some posts w.r.t to rt.jar but I think here the JVM is not the problem.

Thanks & Regards,
Karthik
