Windup eclipse plugin not starting at all

[getgolfedkid]

Hello,

I have installed Windup Eclipse plugin going through the step of this link Windup Eclipse Plugin Guide - Red Hat Customer Portal

However, after configuring the run and launching it I get the charging bar for the server, but then a nullpointerException. I searched about it already but the threads about that exception were for people using command lines and not the eclipse plugin.

I don't know if it's the server configuration that's causing the problem or something else but I put it aswell so you can see what it contains.

I hope you will be able to help me.

Best regards.

Antoine

EDIT : Now the error doesn't even get displayed anymore but nothing happens after the "Starting Windup in Server Mode" window. Moreover, the Windup server is always in [Not Running] mode. Hope that helps.

Interesting, but I would expect the root cause is somewhere in not having set up all input options for running windup/analysis. Are you able to look at your Eclipse workspace and attach here content of <your_workspace_path>\.metadata\.log file?

[getgolfedkid]

Sure, it is quite long so I made a pastebin for more clarity : eclipse .log file - Pastebin.com

I ran Windup many times so I assume it'll be the same error over and over.

Thanks, it seems the RMI connection to server is broken! What version of Windows do you have? I will try to similate that error.

[getgolfedkid]

I'm on Windows 7 Enterprise Version 6.1

Ok, I tried eclipse + rhamt plugin on windows8 and I can see the same connection issue like you. I need to discover what is the root cause if the windows itself blocking the connection or something else. Good thing is that the same build of plugin works on linux.

[getgolfedkid]

It might be Windows' firewall but I have little knowledge in this field so I cannot really help.

Thank you for helping me, please keep me updated about this.

[manarh]

yes, I tried to run rhamt-cli with --startServer 1100 and that is the same command used in plugin and that pops up Windows Security Alert dialog to Allow the connection

I will try to try that in eclipse if that works

[manarh]

So that is part of it, but I can get the NullPointerException now too. I filed [WINDUP-1368] Windup on windows cannot start RMI server - JBoss Issue Tracker  and trying to discover root cause, after that we will it.

Thank you opening an issue about this. While the issue is not resolved is there any way that I can bypass it to be able to use Windup on an Eclipse project? Like a zip installation for instance? 

[manarh]

I would say use linux or MacOSx where the plugin works. Unfortunately whole our team is not using Windows regularly so we were not aware of this issue.

You can use also windup-maven-plugin in your maven project or pure CLI tool.

Hi Antoine, the bug should be fixed now, you can try it with updating from Index of /jbosstools/neon/snapshots/builds/windup-eclipse-plugin-NIGHTLY  or simply uninstall your old one and install the latest version from the URL update site.

Hi, thank you very much for your help. I was using the CLI tool so I didn't see the patch until now.

Hi Marek,

I am getting the below error with registry. I know i am missing something here. I am new to JBoss and Windup.

I am trying to use Eclipse Neon 4.6.3 with JBoss Wildfly integrated. I got the Plugin for Windup and end up seeing this discussion.

I have updated the windup as mentioned in one of the above comments.

I could start the rmi registry on my windows 7 machine using start rmiregistry 1100 command.

Can you please help me out with a suggestion here ? Thanks.

Hi Santosh,

have you started the RHAMT server in IDE?  I don't know why you should use "start rmiregistry 1100" command. It seems what exception says that the RMI service is not found.
