如何以独立于平台的方式在 netbeans 中的 Java 框架内运行外部程序？

Question

I am currently working on a research project for a University in which I am doing GUI interactions with my database and launching an external program based on the data. I'm using runtime commands (once the OS is detected) to launch that external program with the selected data.

My question is how can I embed an external program's GUI inside a Java frame, if that is even remotely possible?

Answer 1

Given the clarifying comments on the question, the short answer is "no, you can't do that".

Java cannot display a native program's GUI within a JFrame, even if the target program was actually architected to allow it's GUI to be presented within another program's frame.

Answer 2

Are you using a console application? You have to intercept its stdout to do it correctly. So you can show the text that the 3rd party application is outputting in an UI control that you can put into JFrame.

Answer 3

It depends from the application you want to embed to the JFrame, but you can try to use jawt: https://docs.oracle.com/javase/9/docs/specs/AWT_Native_Interface.html

You will be able to get the native OS specific window handle and can draw on top of it, or can you use it as a container. Note that only HW components are supported, so you will need to add Panel/Canvas to the JFrame and then use that for your native app.

This is similar to this question: Native JNI/JAWT Swing application runs successfully on Java 6, but fails on Java 7 (64-bit Windows 7 OS)

Answer 4

Use java.lang.Process or java.lang.Runtime.exec.
