writing JNI Invokation app in C to launch tomcat

[Mark W. Webb]

I am writing a C program in Solaris 9 that will use the JNI Invocation API to launch tomcat.  I am doing this because I want to prompt the user for a startup password that will open a PKCS12 file.  I do not want the password echoed to the screen.  

My C program will load a class that I have written, take in the password to open the PKCS12 file, and then call org.apache.catalina.startup.Bootstrap.main( String[] args).  I have looked at the catalina.sh file and am passing the following parameters into the JVM :

-Djava.endorsed.dirs=/usr/local/tomcat/common/endorsed:/usr/local/tomcat/server/lib:/usr/local/tomcat/common/lib:/usr/local/tomcat/bin
-Djava.class.path=/usr/java1.4/lib/tools.jar:/usr/local/tomcat/bin/bootstrap.jar:.
-Dcatalina.base=/usr/local/tomcat
-Dcatalina.home=/usr/local/tomcat
-Djava.io.tmpdir=/usr/local/tomcat
-Djava.library.path=/usr/java1.4/jre/lib/sparc
I am running tomcat-4.1.24 binary distribution.

java version "1.4.1_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_03-b02)
Java HotSpot(TM) Client VM (build 1.4.1_03-b02, mixed mode)
I get the following error when I run my program.  Any ideas would be greatly appreciated.  Thank you.
