Hello, I have a problem to run the the Web aplication Cincom Mantis XML on a SCO 6.0 with MP2.

My Tomcat is 4.1.31

The Cincom support tell me tha I need the Apache Tomcat 5.5 and Java JRE 1.4.0

Can I install a linux version into SCO 6.0 system ?

Thank you for your help.

Yes, but why such an old JAVA? JAVA is generally forward compatible. Later versions not only have richer APIs, they often have better run time options and performance and fewer bugs.

JAVA in UNIX can be anywhere, pointed to by env variables, like $PATH pointing to the bin directory with the java, javac, jar wrappers. Apache is similar, floating on the dir in the env.
