JClass JarMaster provides a built-in manifest file viewer. Use it if you need to review a JAR's manifest file. To view a manifest file:

1. Open or select the JAR whose manifest file you want to view.

2. Click View, then Manifest File. If the JAR's manifest file exists, the Manifest file dialog box appears:

   

   Here, the complete contents of the current manifest file are displayed, including name, path, Bean status, manifest headers, and appended tags.

3. Click Exit Viewer once you have reviewed the manifest file.

4. If you wish to make changes to any particular entries, or create a new manifest file, please see Creating and Editing Manifest Entries. Once you make changes, you can see the changes by viewing the manifest file once again.
