MASES.JNetCLI 2.5.12

title: JNet CLI tool of Java/JVM suite for .NET _description: Describes the CLI tool to use Java/JVM classes from any command-line shell

JNet: CLI

Installation

• dotnet tool hosted on NuGet: check https://www.nuget.org/packages/MASES.JNetCLI/ and https://docs.microsoft.com/en-us/dotnet/core/tools/global-tools for deep installation instructions.
• Docker image hosted on GitHub and Docker Hub: follow instruction within the page and general instruction on https://docs.docker.com
  • The image hosts both .NET 6 and JRE 11 runtimes

[!IMPORTANT] The dotnet tool needs a JRE/JDK installed within the system (see JVM identification)

Usage

To use the CLI interface (JNetCLI) runs a command like the following:

• dotnet tool

jnet -i

[!IMPORTANT] If the previous command raises the error described in Intel CET and JNet, the only solution is to apply the following workaround (within an elevated shell) and disable CET:

  reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\jnet.exe" /v MitigationOptions /t REG_BINARY /d "0000000000000000000000000000002000" /f

• Docker image

docker run ghcr.io/masesgroup/jnet -i

docker run masesgroup/jnet -i

Command switch available

jnet accepts the following command-line switch:

• Interactive (i): Activates an interactive shell
• RunCommand (r): executes the main method of a specific Java class in argument and exit
• Script (s): Executes the c# script in the file arument
• JarList (jl): A CSV list of JAR to be used or folders containing the JARs
• NamespaceList (nl): A CSV list of namespace to be used for interactive shell, JNet namespace are added automatically
• ImportList (il): A CSV list of import to be used

Plus other switches available at Command line switch page.

JVM identification

One of the most important command-line switch is JVMPath and it is available in JCOBridge switches: it can be used to set-up the location of the JVM library (jvm.dll/libjvm.so) if JCOBridge is not able to identify a suitable JRE installation.
