Not able to connect to internet from netbeans #36

Closed isrgish closed 3 years ago

isrgish commented 3 years ago

I'm running netbeans 12.4 on an Android device in a proot shell that is running a ubuntu dist. I;m using a vnc to connect to it and that's how I have a desktop. I'm able to connect to the internet with Firefox on this desktop without any problems. But in netbeans I get the following error when I tty to check for updates, plugins or anything else that it needs to connect. Error Message "Unable to connect to the NetBeans Distribution because of java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty" End Error Message I have searched around for a solution and found to export _JAVA_OPTIONS='-Djava.net.preferIPv4Stack=true' or to add -J-Djava.net.preferIPv4Stack=true to netbeans_default_options in netbeans.conf file. I have tried this but without success.

What can I do to resolve this issue?

I won't be able to reproduce and I can't say for sure. But it looks like a TLS error of some sorts. Most likely it can't access the trustStore.

isrgish commented 3 years ago

I'm new at all this. Can you explain what is this TLS and what is the trustStore?

Is there anything I can do to help it access this trustStore?

I just upgraded to openjdk 16 and I'm able to download and connect without a problem.

Hey @isrgish, that's great news. Would you mind close this with a comment explaining how you fixed it step by step? Thanks

isrgish commented 3 years ago

To fix this issue I installed OpenJDK 16 and made _JAVA_HOME point to it and now I can download.

@isrgish did you install the openjdk's flatpak from Flathub?
