Apple OSX Leopard, Netbeans 6, cannot create new java class

[Nicola Maggi]

Hello,
I have a problem trying to add a new class to my project.
This issue also occurs when I try to create a new project. Te lower
left bar stops at 25%.
I append the stacktrace of the error, I even compiled a report to
issuezilla, finding out that other people have the same issue.

Reading some forums on the web I figured out that it could be a java
sdk version mismatch.
Apple released on 30/4/2008 a java update to version 6, some says it
could have caused this problem.
Anyway I'm looking for some kind of workaround.
here's my configuration:

Product Version: NetBeans IDE 6.0.1 (Build 200801291616)
Java: 1.5.0_13; Java HotSpot(TM) Client VM 1.5.0_13-119
System: Mac OS X version 10.5.2 running on i386; MacRoman; it_IT (nb)
Userdir: /Users/nick2k3/.netbeans/6.0


Can anyone help?

Thank you,
Nicola Maggi

Look at the .netbeans/6.*/var/log/messages, look at the latest lines  
just after you reproduced the bug and let us know how they look like.

Could be related to:
    http://www.nabble.com/New-Project-Wizard-hangs-td15584115.html
    ...probably you have installed Java SE 6 Developer Preview 9 recently.
    The installer puts AppleScriptEngine.jar into
/System/Library/Java/Extensions
    folder. This jar file is compiled with jdk6 and because Extensions
folder is shared by
    all installed jdk versions, this is cause of the problem. Just
remove this jar and
    it will be fine...

Nicola-

 

I've seen similar error messages when something is being compiled with one version of Java (e.g. Java 6) and someone attempts to run it under another version of Java (e.g. Java 5). I would check your configurations for compilers and runtimes within NetBeans and also in the command line environment.

Subject: Apple OSX Leopard, Netbeans 6, cannot create new java class
Hello,
I have a problem trying to add a new class to my project.
This issue also occurs when I try to create a new project. Te lower
left bar stops at 25%.
I append the stacktrace of the error, I even compiled a report to
issuezilla, finding out that other people have the same issue.

Reading some forums on the web I figured out that it could be a java
sdk version mismatch.
Apple released on 30/4/2008 a java update to version 6, some says it
could have caused this problem.
Anyway I'm looking for some kind of workaround.
here's my configuration:

Product Version: NetBeans IDE 6.0.1 (Build 200801291616)
Java: 1.5.0_13; Java HotSpot(TM) Client VM 1.5.0_13-119
System: Mac OS X version 10.5.2 running on i386; MacRoman; it_IT (nb)
Userdir: /Users/nick2k3/.netbeans/6.0


Can anyone help?

Thank you,
Nicola Maggi

Well, it's not a Java 6 issue, since NB is running under JDK 1.5  
(assuming the above is correct).

Maybe the AppleScript extension, but I run fine with it in place.

I do however have one major file create/delete hang'ing issue that I  
tracked down to an old Wicket plugin. Installing the updated plugin  
corrected the hang.

Remember there are 3 cases where the version of Java comes into play.

 

1) Under which version of Java are you running Netbeans (probably doesn't bear on your problem)

2) Under which version of Java are you compiling your applications.

3) Under which version of Java are you running your applications.

It's a problem of the Apple JDK 6.0 installer. The problem is fixed in  
the NetBeans 6.1.
