M-Files Web and Java
Posted by Timo Lahti on 21 January 2014 02:35 PM

M-Files Web uses an M-Files Java applet for facilitating file access operations. However, with the updates in Java Runtime Environment (JRE) and updates in new browsers, the applet may not work without some manual changes, for instance, to Java security settings.

Note: Microsoft Edge and Google Chrome (versions 45 and later) do not support Java. M-Files Web can be used with these browsers, but certain file operations are unavailable. For instance, modifying files with these browsers might not be as effortless as with browsers supporting Java. M-Files will provide a solution to support file access for these browsers in the next M-Files release.

Troubleshooting

Follow the steps described below for resolving the Java issue in a browser without restrictions in Java use.

Windows

  1. Install the latest Java Runtime Environment version to your workstation by upgrading the version you currently have.

  2. Restart your computer.

Please also check the tips provided at: https://www.java.com/en/download/faq/win8_faq.xml.

We recommend using 32-bit Java. The guidelines below are for 32-bit Java.

If this did not bring the M-Files Web functionality back, follow these instructions:

  1. Ensure, that the latest version of Java is installed properly and that it is in use.
    • Open Windows Control Panel > Java (32-bit) > About.

  2. Restore security prompts in Java Control Panel.
    • Open Windows Control Panel > Java (32-bit) > Security > Restore Security Prompts.

  3. Remove all the downloaded mffta.jar resources from the Java cache.
    • Open Windows Control Panel > Java (32-bit) > General > Temporary Internet Files > View...
    • From the Show dropdown menu, select Resources.
    • Delete all the resources named "mffta.jar".
 
 

OS X

  1. Install the latest Java Runtime Environment version to your workstation by upgrading the version you currently have.

  2. Restart your computer.
 
If this did not help, follow the steps further above described for Windows. In OS X, you can find the Java settings via System Preferences > Java

Adding Site Exceptions

If a Java applet on a certain page has been disabled, the Java applet on the page will remain blocked even if it is reallowed to run on the page.

The easiest and correct way to fix this is to add a security exception to the "Exception Site List" in the Java settings:

  1. Open Windows Control Panel > Java (32-bit) > Security.
  2. Check that "Enable Java content in the browser" is enabled.
  3. Set Security level to "High".
  4. Add exceptions by pressing the "Edit Site List".
    • You must add the site with the http:// or http:// prefix.

Once you have finished adding the exceptions, it is still good idea to restore the security prompts:

  • Open Windows Control Panel > Java (32-bit) > Security > Restore Security Prompts.

After closing and opening the browser again, these settings should be effective. The last thing to do is to re-enable Java for M-Files Web.
