Re: "FATAL ERROR in native method: Expected a string"

["Bruce Jin" <JIN007M@xxxxxxxxxxx>]

Hi Alex; Thanks for the reply.

I checked Tomcat home for 4.1 installation instruction and it says "Download
a Java Development Kit (JDK) release (version 1.2 or later)". Besides we
have Tomcat 4.1.12 running on two As400 boxes that are on jdk 1.2.

Since this box never ran java before there may be some jdk or other related
problems.

Bruce

> I installed tomcat on an AS400. This box has jdk1.2.  The is the first
time we try run Java code on this box. I started tomcat and it I got the
error "FATAL ERROR in native method: Expected a string".   It appears that
it failed when the system tried to attaching JVAPGM to tomcat jar files
because the failing point is where I usually see "Attaching Java program to
xxx.jar file" messages.
