Fixing Unable to access jarfile fmw_14.._infrastructure... Error • Vinish.Dev

When installing Oracle Fusion Middleware, you may encounter the error:

Error: Unable to access jarfile fmw_14.1.2.0.0_infrastructure_generic.jar

This happens when the installer cannot find the required JAR file at the expected location. The issue is not with the file itself but with its directory path.

Why the Error Occurs

The Java command that runs the Fusion Middleware installer looks for the JAR file in a specific path. If the file remains inside the Downloads folder or a path with spaces/special characters, Java may fail to access it.

Solution

The fix is very simple: move the JAR file into a clean directory path (for example, C:\fmw) and then run the installer again.

Steps:

Go to your Downloads folder.
Locate the file: fmw_14.1.2.0.0_infrastructure_generic.jar
Cut and paste the file into a new folder, such as: C:\fmw
Run the installation command again from the new folder: java -jar C:\fmw\fmw_14.1.2.0.0_infrastructure_generic.jar

Conclusion

If you face the “Unable to access jarfile fmw_14.1.2.0.0_infrastructure.jar” error during Oracle Fusion Middleware installation, simply move the fmw_14.1.2.0.0_infrastructure.jar file to a clean directory (like C:\fmw) and run the command again. This resolves the issue immediately.
