JNI in CPP plugin

Narfi Forshaken

Has anyone tried to create a jvm using jni in a cpp plugin?
I am trying to create a plugin that call java functions.
During initialization of plugin, the createJavaVM call hangs and there seems to be no further process.
Has anyone done this before and give some advice on this?

I created a exe which calls the createJavaVM from the dll. This works.
I created a new dll with the same code and called the function.
Is there any difference how a plugin dll is loaded in npp?

I use Visual Studio 2010 Professional and Visual Studio 2015 Community Edition. Tried creating plugin dll in both, and the issue in creating jvm exists.

.net framework 4.0 should be installed for c# plugin API(x64 build)
for c++ plugin API use latest Plugin Template

if
- Write a script using clojure (a lisp dialect) on jvm.
- Write a script using clojure-clr (a lisp dialect) on .net.
and
- JVM and .net have a very strong ecology
- Clojure is better than elisp
- Notepad++ is better than emacs
Then
- Notepad++ will become emacs#

EMACS --> Notepad++
elisp --> Clojure / Clojure-CLR

@gurikbal-singh I am already using the latest plugin for development, the one provided in the link. I also have the .rc file as stated by the issue you linked above.

@linpengcheng I will try this and update

@linpengcheng While trying using Clojure, I moved the CreateJVM function from pluginInit function to plugin menu item.
This creates a JVM without any issue.
