问题
I have no problem in my internet connection. But getting every time this screen when I try to update netbeans plugins or IDE itself.
Even OS reintallation doesn't fix this issue. Getting same error again and again. How can I fix it?
回答1:
In Netbeans
Go to
- Tools->Plugins->Settings
and
- Add a new one or change the URL of "JAX-RPC" to the one referred below
URL: http://bits.netbeans.org/dev/nbms-and-javadoc/lastSuccessfulBuild/artifact/nbbuild/nbms/updates.xml.gz
回答2:
Netbeans 8.0.2/Tools/Plugins/Settings.... found a bad url ie URL: http://netbeans.i2m.dk/updates.xml
Unchecked the Active column for "I2M Update Center" and the "Check for Updates" now works.

Are you behind a proxy? If yes, you can change your settings at Tools -> Options -> General (Proxy Settings)
回答4:
Are you using Firewalls? May be its blocked by your firewall,
try to check the blocked applications.
Update
probably yes, because Kaspersky most of time will block without notice or accidentally might be blocked. so better try to check blocked application lists in kasperksy. Check this links might help you to solve:

Check your Netbeans log - messages.log file - for details of the error!
Example locations of the file:
Linux: ~/.netbeans/7.3/var/log/messages.log
Windows: c:\Users\USERNAME\AppData\Roaming\NetBeans\7.3\var\log\

This might have been a late reply, however, i just experienced the same issue today. I went to Tools > Options > General, and chose "No Proxy". Hit "Apply and Ok". Instead of trying to update again, i just closed netbeans completely, relaunched it and it went to detect updates automatically. All went back to normal.
