How to Run Java Applications with Administrator Privileges?

Run Java Applications as Administrator

In Java, it is possible to request administrator privileges for your application without the need for manual user input. This is achieved by creating a manifest file that defines the application's requirements.

Creating the Manifest File

To create the manifest file, use an XML editor like Notepad . The manifest should have the following format:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<manifest xmlns="urn:schemas-microsoft-com:asm.v1">
  <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
    <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
      <security>
        <requestedPrivileges>
          <requestedExecutionLevel level="requireAdministrator" />
        </requestedPrivileges>
      </security>
    </trustInfo>
  </assembly>
</manifest>

Embedding the Manifest

You can embed the manifest within the JAR file using the -manifest option during compilation:

jar -cvfm myapp.jar META-INF/MANIFEST.MF myapp/*.class

Alternatively, you can externalize the manifest as a separate file named myapp.exe.manifest. In this case, specify the manifest in the Main-Class entry of the original manifest:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<manifest xmlns="urn:schemas-microsoft-com:asm.v1">
  <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
    <entryPoint>
      <assemblyIdentity version="1.0.0.0" name="myapp" type="win32" processorArchitecture="*" />
      <commandLine file="myapp.exe" parameters="" />
    </entryPoint>
    <dependency>
      <dependentAssembly>
        <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="*" publicKeyToken="6595b64144ccf1df" language="*" />
      </dependentAssembly>
    </dependency>
  </assembly>
</manifest>

By specifying the requestedExecutionLevel in the manifest, your application will prompt the user for administrator privileges through the UAC dialog when executed.
