KB-1707 "Execute Weblogic installer using JDK" error while running Weblogic JAR file


The Weblogic fmw_xx.x.x.x.x_wls.jar file fails to execute the following error:

Extracting the installer . . . . . . . . . . . . . . . . . . . Done
This installer must be executed using a Java Development Kit (JDK)
but C:\Program Files\Java\jreX.X.X_XXX is not a valid JDK Java Home.


This error occurs because the installer is unable to recognize the JAVA_HOME environment variable.


1. Ensure that the JAVA_HOME is set correctly as per the documentation

2. Navigate to the <JAVA_HOME>/<JDK_VERSION>/bin directory.

3. Execute the command: java -jar <PATH_TO_WEBLOGIC_fmw_xx.x.x.x.x_wls.jar_FILE>.

Affected Versions

This article applies to all versions of Appian using Weblogic as the application server.
