Internet application won't register with "unable to delete.... parent.lock file" error message.

Firefox 3.6 requires Selenium 1.04 or higher. If you are using these versions of Firefox and Selenium to create Internet macros for the Internet application, you will get an error message that Longitude is "unable to delete" a file named "parent.lock".

This is fixed by an updated selenium-server.jar file. To put this in place, do the following:

  1. Download the updated selenium-server.jar file.
  2. Stop the Longitude services.

kb938: Longitude Internet Application and Firefox / Selenium versions

The Internet application uses macros created by the Selenium plugin in Firefox to script internet transactions. The following list displays the compatible versions of Longitude, Firefox, and Selenium:

Longitude 6.1.x and earlier:

  • Firefox 2
  • Selenium 0.8.6

Longitude 6.1.x (using patched selenium jar file) and Longitude 6.2.1:

  • Firefox 3 - 3.5
  • Selenium 1.0.2

****Note:

kb933: Unable to view Longitude using SSL with Firefox 3.x

The default certificate used by Longitude for the https Monitoring Console is self-signed. Some browsers will allow you to accept the certificate to view the Web UI, but Firefox 3.x and other browsers will not allow you to accept a self-signed certificate.

To work around this, you can configure the Longitude Web UI to use a certificate generated by a certificate authority trusted by Firefox. Details on how to configure Longitude to use a trusted SSL certificate are found in kb230: Using a trusted SSL certificate with Longitude's Web UI.

6.2: Auto Upgrade of Firefox May Remove Selenium

It has come to our attention that an Automatic Update of Firefox may remove Selenium. You should disable Automatic Updates on the Machine executing the internet macros so that this does not happen. You can disable the automatic updating on Firefox by performing the following.

  • Go to Tools > Options > Advanced > Update.
  • Uncheck the checkbox that says automatically check for updates.

kb230: Using a trusted SSL certificate with Longitude's Web UI

Longitude provides a self-signed certificate when it is installed for basic site encryption. Since this certificate is not signed by a trusted certificate authority, Firefox 3.x may not allow you to view the Longitude Management Console in SSL using the default certificate, and other browsers may display security warnings.

6.1.x: Using Firefox 3.0 and higher with the Internet Macro

Firefox 3.0 and the latest version of Selenium can be used to create internet macros in Longitude 6.2. If you would like to use these features in 6.1.x you will need to grab the selenium patch (Right Click Save Target As), and do the following:

  1. Stop your Longitude services from services.msc
  2. Proceed to drop the firenze.jar files in Longitude\DC\Lib overwriting all files.
