Question related to jar file

Hi,
Do I need to regenerate the relevant executable jar file (using SDK 1.3.1), which was previously running fine within WinXP machines, if I expect them to also work within Win 7 machines?

BTW, which tool is used to generate such jar file that is based on SDK 1.3.1?

The version of the operating system is not really significant. What IS significant is what version of Java the jar was compiled to and what version of runtime is there on the machine on which you want to run it. Do you actually have the source code?

My bad :)
CEHJ is right. Jar.exe is the specific tool inside JDK1.3's bin folder here

I think there is no source code to the relevant JAR files. How to ensure which application tool had been used to create the JAR files? What kind of file extension are the source project with?

ANY tool ultimately uses the jar utility (whether in its form as a native executable or java class) to create jar files.
What kind of file extension are the source project with?
In Eclipse, you will .project files and .classpath files. If it's been created with Eclipse, you should find build-impl.xml files

Many thanks.
Does it mean

.project files and .classpath files

are having all the source, if it is in Eclipse?

CEHJCommented:
No. They just indicate it was created in Eclipse. Java source is always .java files, whatever it was created in
