I'm currently planning to learn Java through the MOOC course but I'm unable to open the tmcbeans app after installation. I have tried reinstalling it but it does not seem to do anything. Any help would be much appreciated.

Thank you.

I had a similar problem in macOs Monterey and the following steps got tmcbeans up and running for me:

  1. Open Terminal and type /usr/libexec/java_home-v'1.7*' (copy/save the result)
  2. Open Finder and go to Applications -> tmcbeans.app
  3. Right click on tmcbeans.app and select Show package contents
  4. Go to Contents/Resources/tmcbeans/etc/ and open tmcbeans.conf in your preferred text editor
  5. Scroll to the bottom and you will find #jdkhome="some path here..."
  6. Copy the result from Step 1 and paste it between the double quotes in Step 5
  7. Remove the hash symbol at the begining to make it jdkhome="your path here ..."
  8. Save, Quit and Restart tmcbeans.app

I signed up for MOOC too, and what worked for me was to follow the steps to locate the JVM path of this video

My java ended up being under /Library/Java/JavaVirtualMachines/temurin-11.jdk/Contents/Home

I then updated and uncommented the line jdkhome= of tmcbeans.conf (as described in the comment above), saved and relaunched tmcbeans. It worked perfectly after that.

Good luck!

I was facing the same issue on Windows 10. I found out that TMCBeans is currently not compatible with OpenJDK Versions > 11. Thus, I did the following things for TMCBeans to function correctly.

  1. Download exactly AdoptOpenJDK11 for your OS, open development environment for Java 11, from the archives.
  2. Try launching TMCBeans again.
  3. If you're still facing issues, try following the instructions of this Reddit post's first comment.
