A solution to restore the .jar file association to the Java Runtime Environment

editor's review





Jarfix is a nifty little utility designed to repair JAR file associations. It’s small, extremely easy to use and does not require installation.

The JAR extension, a proprietary format of Java, is an archive that aggregates a collection of Java classes in order to run cross platform applications. In order to successfully launch a JAR file, you are required to install the Java Runtime Environment.

More than often and not only in JRE’s case, file associations are misplaced when installing various software applications. Typically, JAR associations are ‘stolen’ by archive managers and sometimes not even the experience of professional users can solve this issue.

There are three solutions to this matter, Jarfix included. You can install Java Runtime environment all over again or perform the association yourself (click Properties and set the path to javaw.exe). But the third solution is the simplest one and its name is Jarfix.

Jarfix reduces your efforts to two clicks in total. All you are required to do is double-click the exe file, at which point you are confronted with the main and only window of the application. It’s more like a dialog that explains the steps that the program performs in order to restore associations. A click on the ‘OK’ button suffices to complete the repair process.

You can verify if the operation was successful by running a JAR file. If the problem persists, you are going to need more advanced solutions and the first we can think of is start tweaking registry entries (not recommended for beginners).

For testing purposes, we associated the JAR extension with another application and then launched the fix to check if it works. We’re pleased to state that it did.

In conclusion, Jarfix is the quickest fix for JRE that we have come across. It’s lightweight, portable and guaranteed to work.
