Question

Using windows server, I have a path to a file that, when you click the button, executes the jar file and runs the program. At least in firefox. The problem occurs with IE6. It takes my file.jar and turns it into file.zip. Any suggestions here?

Answer 1

Firefox can determine correct mime-type by extension first, and check header information to find out if there’s a congruent match. IE6 unfortunately doesn’t.

JAR file is actually is a ZIP file (rename a JAR file to zip and it’ll be opened easily with Winzip) change the JAR mime-type to “application/java-archive“.

Update

On IIS:

1. Select the site to configure in IIS, right click and select “Properties”
2. Under HTTP Headers Tab, select “File Types” under the MIME Map section and select “New Type”
3. Type “.jar” as the associated extension and “application/java-archive” as the content type.
4. Select “OK” and you’re ready to go!
5. Restart IIS.
