无法在Eclipse上安装glassfish支持

Question

This is the problem i face when i try to download glassfish support on eclipse. What is this ? And how can i get rid of this ?

Answer 1

Read timeout when trying to reach the jars required for installation. Do other updates work within eclipse? Is network connection fine outside eclipse? If fine outside eclipse check eclipse network settings. If not fine outside eclipse check OS network settings first.

For Eclipse select from menu: "Window" > "Preferences". Then type filter text "network" or select "General" > "Network Connections". There you can define proxy if needed.
