File -> New -> Project -> D Project -> "The selected wizard could no be started. Reason: unable to load class descent.ui.wizards.DProjectWizard" (Paraphrased)

I followed install directions on wiki page, and installed about 10 mintues ago.

That's strange.

Could you tell me please what operating system you have, what is the destination folder for your new project and where is your workbench? Maybe we can work it out.

Thanks,
Ary

OS is Linux.
workspace is /home/teqdruid/workspace
Eclipse asks to select the wizard before asking for the destination, so there is no destination before I get the error.

I checked, and DProjectWizard does appear in descent.ui_0.1.20061228.jar, so I'm not certain why eclipse can't find it. It's able to locate the jar, since it's getting descent.ui.wizards.DProjectWizard from plugin.xml from the jar... Any ideas?

I'm on Windows. These days I'll try to install Ubuntu or something and try it on linux. When I'm done with that, I'll tell you.

Hum, interesting and odd... I've just had a problem today that seems very similar. I was preparing to show my branch of the Eclipse D IDE to my thesis/final-project professor in his laptop (which was a Linux - Ubuntu instalation), and I got class not found errors on all extension points (such as opening the editor, or executing actions), despite Eclipse finding the plugin jars and everything seemed to be well configured.
I later tried on a Windows public PC in a university lab and it worked fine. I tried in a Linux Ubuntu on the same public PC and it worked fine! Confused
So I was left without any ideia of what is wrong.

teqdruid, could you try creating a .d file and see if the Descent editor opens it (to see if it can load any other plugin component)? And also, could you try installing it on another computer/OS ?

Hum, could you try running Eclipse with the -clean option, to see if there is any effect?

I am experiencing the same issue under WinXp.

My eclipse installation is in c:\code\eclipse
I looked inside the descen.ui*.jar\descent\internal\ui\wizards; the class is there but I see and error when trying to load it:

Quote:
The selected wizard could not be started.

Reason
Plug-in descent.ui was unable to load class
descent.internal.ui.wizards.JavaPerojectWizard

Same error here

WinXP, Eclipse 3.2.1, clean install. Also, creating a "file.d" produces this error:

"Unable to create this part due to an internal error. Reason for the failure: The editor class could not be instantiated. This usually indicates that the editor's class name was mistyped in plugin.xml."

This is very strange. Can you install version 0.3 and tell me if it also happens? If yes, could you post the error log?

Thanks.

I found it: Descent uses generics, you'll need Java 1.5 or greater.

I added this to the installation documentation.

Hi,

I'm experiencing this issue. I'm running in Linux.

kyle@frozen:~/eclipse/plugins$ java -version
java version "1.5.0_10"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_10-b03)
Java HotSpot(TM) Client VM (build 1.5.0_10-b03, mixed mode)
kyle@frozen:~/eclipse/plugins$

I'm using descent.ui_0.4.3.20070907.

These errors appear everywhere, prohibiting my use of the plugin whatsoever.

Please help.

Kyle

Please check that the java version used by Eclipse is indeed 1.5. To do this, open Eclipse, go to Help -> About Eclipse SDK -> Configuration Details. There, check the value of "java.runtime.version". If it's 1.5, please reply back.

Thanks!

Hi,

java.library.path=/opt/jdk1.5.0_10/jre/lib/i386/client:/opt/jdk1.5.0_10/jre/lib/i386:/opt/jdk1.5.0_10/jre/../lib/i386:/usr/lib/firefox-1.5.0.9
java.runtime.name=Java(TM) 2 Runtime Environment, Standard Edition
java.runtime.version=1.5.0_10-b03

I added some more information to my previous post. It may prove useful.

Thank you.

Clean up the error log and run Descent again. Try to create a new project. It will fail, of course. Then send me the full error log. When it happened to me, I found out that many entries are created in the error log. The last one is the one you send, but previous entries say something about the class versions...

Thanks!
