How to Fix ‘Failed to Load the JNI Shared Library’

Eclipse is an open source project which uses a Java plugin system to allow programmers programming in different languages to work together easily. It’s available for many platforms as well. The error mentioned in the title of the article is an error which appears after users try to open Eclipse on their Windows PC.

Failed to Load the JNI Shared Library

Eclipse usually just closes afterward. The problem often appears as soon as users install and run Eclipse. There have been many different methods used to resolve this problem and that is why we have gathered them in a single article for you to check out!

What Causes the ‘Failed to Load the JNI Shared Library’ Error?

The problem is often caused by one or two common issues which are shared among many users who have reported the problem online. Still, there are several ways to deal with the same problem. Check out the list below:

  • Mismatching versions of Eclipse and Java Runtime – Both programs must be either 64-bit or 32-bit or this error is bound to appear. Resolve the problem by switching both programs to the same format.
  • Both the 32-bit and 64-bit versions of Java installed – Eclipse might try to access the wrong one and you should guide it to the proper version by manipulating the Path variable.
  • Eclipse is unaware of the installation folder of Java – You should clarify the confusion by including it in the eclipse.ini file.

Solution 1: Edit the ‘eclipse.ini’ File

This specific problem can occur of the installation of Eclipse fails to understand just what the correct path to the executable might be. That can be resolved easily simply by adding a line inside the Eclipse configuration file available in the installation directory. Make sure you follow the instructions below in order to resolve the problem.

After locating the Java folder, navigate to jrex.x.xx > bin and locate the ‘jawaw.exe’ file. Click the address bar and copy the full address to Clipboard. The ‘x.x.xx‘ placeholder represents the version of Java you have installed.
