Debugging Drop-In PlugIn

[Daniel Seidinger]

Hi, I am part of a team currently developing a new PlugIn and my question is that if there is a way to check why a jar file doesn't show up as a plugin in JCryptTool. I used the guide on the website on how to export it and the plugin is already running as a stand-alone programm. It would be great if you could help me.

[Dominik Schadow]

Hi Daniel,

Have a look at the JCrypTool About dialog and the plug-ins listed in there. Your plug-in should be visible too. After that check the JCrypTool log file located in user.home/Documents/.jcryptool. Maybe you'll find an exception or error in this file.

Okay, it shows up as being part of it and I only found a help missing error because we haven't implemented it yet, could this be the cause?

[Dominik Schadow]

No, that shouldn't stop your plug-in from being loaded. Which JCrypTool extension point are you using, where do you expect your plug-in to be visible?

[Daniel Seidinger]

We are using the visual menue extensionpoint, so we are expecting it to be under visual.

the only error related to the program I could find.

[Dominik Schadow]

Please post your repository URL where I can find your plug-in.

[Daniel Seidinger]

It isn't on any public repository atm, I could send you the sourcecode tho.

[Dominik Schadow]

Yes mail that to me.

[Dominik Schadow]

You do not extend the org.jcryptool.core.operations.visuals like any other JCrypTool visuals plug-in (have a look at these plug-ins). Your plug-in will not show up in JCT without that. And remove the hardcoded zest classpath entries in the .classpath file, this will not work during runtime anyway.

What exactly do I need to change because we are currently already extending the org.jcryptool.core.operations.visuals but it is still not working, can you maybe be more concrete in what has to be changed?

[Daniel Seidinger]

Okay, it now shows up int the menue, but it doesn't open anything, in the error log I found this.

Okay, we now can launch our plugin by going to windows -> Others -> klicking on the plugin. It currently doesn't work via the normal menue but it does show up there.
