Saya mencoba menginstal aplikasi Java di mesin Linux saya (Slackware).
Saya telah menerima kesalahan berikut, dan saya tidak memahaminya.
Bisakah Anda memberi tahu saya bagaimana menangani masalah ini? Terima kasih.
Inilah yang saya dapatkan: (Saya melihat bahwa beberapa variabel TAMPILAN X11 perlu disetel, tetapi nilai apa yang harus saya berikan dan bagaimana?)
~$ java -jar gate-5.0-beta1-build3048-installer.jar
- ERROR -
java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.
