Tomcat 3.2.3: "method x used to be static" error

[Wolf, Markus, Triaton/DE]

Hello,

I get an error message if I am changing a object method into a static
method; I deleted the subdirs of the work folder and restarted tomcat to
assure that changes take effect.

I am using Tomcat 3.2.3, Sun JDK 1.2.2 on Windows NT 4.0 SP5 english.

Error message:
...
Internal Servlet Error:

javax.servlet.ServletException: <classname>: method
e(LS;Ljava/lang/String;)LC; used to be static
        at org.apache.jasper.servlet.JspServlet.service(JspServlet.java,
Compiled Code)
        ...

Root cause: 
java.lang.IncompatibleClassChangeError: <classname>: method
e(LS;Ljava/lang/String;)LC; used to be static
        at ...
        at
org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:119)

I did search the tomcat user archive, Google and Google groups, but did not
found anything useful.

        Thanks in advance and kind regards
