org.apache.jasper.JasperException: Unable to compile class for JSPNote: sun.tools.javac.Main has been deprecated. error: Invalid class file format in C:\Program Files\Apache Tomcat 4.0\webapps\muthu\WEB-INF\classes\SQLBean\DbBean.class. The major.minor version '49.0' is too recent for this tool to understand.

The error message is clear enough. You are compiling the class(es) with a higher version of JDK than what Tomcat 4.0 is supposed to use. From the major.minor version = 49.0, I guess you are using JDK 1.4. If you want to generate classes compatible with the older versions [JDK 1.3 in your case], you will have to make use of the-source and -target options while compiling your class. The source option specified as "1.3" will indicate that the source files are compatible to JDK 1.3 and the target option set to "1.3" indicates that the generated classes will be compatible from JDK 1.3 onwards.
