Can I use applications using Java 1.4.2_12 and Java 1.5 on the same Windows server?

Question

I have several applications running on Java 1.4.2_12, and now you need to add a new application using Java 1.5. Can I have java versions on a windows server?

Answer 1

Yes. You just need to make sure that each one has the correct version of Java / JRE in its CLASSPATH, PATH, and JAVA_HOME environment variables.

Answer 2

Yes: in fact, the JDK or JRE can simply be "copied" wherever you want and not "installed" (avoiding putting anything in c: \ Windows \ System32)

But I'm not sure what your problem is. Do you run a client application (swing)? Two Java processes for providing services? or do two applications use the same Java application server?
