Problem configuring tomcat 4.1.18 LE with IIS 5.0/JDK1.4 using jni

[Vikas Manocha <vi...@yahoo.com>]

I have succesfully been able to configure tomcat
4.1.18 LE to work with IIS 4.0/JDK1.4 using sockets. I
would like to configure it to use JNI though and
that's where I am running into a problem. When I
configure with JNI, it is able to successully load the
example webapps, but not my webapp. The difference is
that my webapp is compiled using JDK1.4. This is the
error I get:

I have set the JAVA_HOME environment variable to point
to jdk1.4 and also pass java.home as jvm argument. I
also include tools.jar from jdk1.4 in the classpath as
jvm argument. I was under the assumption that the LE
edition of tomcat 4.1.18 is supposed to work with
JDK1.4. Is there something else that I am missing?

thanks in advance for your help,

Vikas.
