Data Loader process.bat Error: The system cannot find the path specified

When trying to run process.bat for Salesforce's Data Loader from the command line, I encountered an error, "The system cannot find the path specified."

The problem turned out to be that I was not running process.bat from the %DATA_LOADER_HOME%\bin folder.

Running process.bat from the folder where the BAT file was located (shown below) solved the problem.

The root cause of the error is that process.bat (in Data Loader 28) looks for the JRE executable in a relative path, assuming the user is running the script from %DATA_LOADER_HOME%\bin.

How to Install Java 7 Plugin for Firefox on Windows Server 2008 R2

If you have to set up Windows Server 2008 R2 environments and try to get the JRE 7 plug-in to work in Firefox on the server, you may not have found it to be an intuitive process.

The quickest solution seems to be:

1. Open Google, and search for "java plugin verify"
2. Click the result with a title similar to "How do I test whether Java is working on my computer?" See the screenshot below for reference.
3. Click the Free Java Download button
4. Click the Agree and Start Free Download button. This should prompt you to download an installer such as "jxpinstall.exe".
5. Once the download is complete, close Firefox
6. Run the installer, and follow the on-screen instructions to complete the installation
7. After the installation, return to the verification page to make sure the Java plugin for Firefox now works

For some reason, downloading and installing the JDK or the JRE from Oracle's website does not install the plugin correctly for Firefox. This is the only reliable way I've encountered so far of getting the plugin to work in Windows Server 2008 R2.
