Frequently Asked Questions

Q: When I click About in the Jarx submenu in Programs, or when I run jarx.exe I see an About dialog box but nothing happens. Is something wrong?

A: No, nothing is wrong. Jarx works invisibly and comes in action when you run (double click) a file with the .jar or .jarx file extension.

Q: Starting JAR files doesn't work anymore. How can I get Jarx working again?

A: You probably installed a program that "stole" the .jar file extension. Some unzip progams do this. You have to re-install Jarx.

Q: Does Jarx work with Java 1.1 programs?

A: Yes. You can make a JAR file and Jarx will first try to run your program in a Sun JVM and when that fails, it will try the Microsoft VM.

Q: How do I create a JAR file?

A: See Sun's JAR Tutorial. Don't forget to add the Manifest with the Main-Class-header.

Q: Can I use distribute Jarx with my own Java software?

A: Yes, Jarx is MIT-licensed. See Jarx for developers for more information.
