I'm stuck in this problem from 3 days and i don't find any solution. I'm developing a DM application with NetBeans 7.3 using the Weka developer edition (3.7.10). I'm trying to use the Snowball stemmer and I keep getting the same exception while I run my application at the moment I create the stemmer with:
SnowballStemmer stemmer = new SnowballStemmer();
the exception I get is:
Refreshing GOE props...

The first thing I would like to say is that the snowball.jar is included
file in my java project. The first strange thing is that I never use weka.classifiers.JythonClassifier. The next thing is that I'm using Weka-7.3.10 and in this version the JythonClassifier extend from AbstractClassifier. It seems that the JythonClassifier found is some old version.
When I began with this project I start using thee Weka Stable Edition (3.6) but then I migrated to the developer edition (3.7). So I thougth there could be some old Weka library somewhere, thus I:
unistalled the Weka
deleted wekafiles directory
deleted any weka.jar file from my disk
installed Weka again
But I still keep getting the error.
I was searching quite a long for a solution, but found nothing... The useDynamic properties from GenericPropertiesCreator.props is set on true.
Would be really gratefull for any idea..... because I'm running out of them.
Thanks!
Snowball stemmer is available as a jar file in the following link along with its usage
http://preciselyconcise.com/apis_and_installations/snowball_stemmer.php. The jar file can be included in your classpath

Please help me on this issue thanks in Advance.
trying to read data from the Excel file saved in MS Office 2010 brings this error up. Saved the file as an Excel 2003-07 and then it will read without any problem. or even "Excel 97-2003 Workbook" type will solve the issue.

How can I do this ?
Since going to 1.7.0_45 (and 51) my program sometimes hangs. All of it's windows work OK except for one, it's fairly complex and has around 60 JButtons, JTextFields, two JScrollbars, JLabels etc. But so do all my other windows and they work fine.
I've put debug lines to the console so I can see where the program is hanging and it seems to be during the repaint() fn. It's hanging at the line
Graphics g = getGraphics();
It has managed to draw some stuff to the screen so it's not the first call to repaint that's the issue. Looks like this: http://www.unixnerd.demon.co.uk/hungjava.jpg
I get this StackTrace. None of the lines of code are in my program. It only happens maybe one time in ten if I open and close the window. Never had the issue with Java 1.6.x. Happens on a few PCs (all Windows 7), not just mine.
Grateful for any ideas.

Im working on my old project at the moment using jide libraries, I used netbeans as my IDE, it works fine when I was working with it in Windows 7 a year ago.
Currently I'm using OS X Mavericks and using netbeans 7.2.1, when I try to drag the component from the palette manager i got this error.
Got anyone also encounter this?

Added the error log:

You get this error because your code is compiled against JDK1.6 but your runtime is not. In my case it was JRE1.7
You can fix this by making sure you JRE and JDK are the same versions.
For me, I changed my eclipse run config from 1.7 (default) to 1.6

The most likely explanation is that you don't have log4j in your class path (which is why it can't find it)
dcm4che jar uses Log4J framework for logging its trace and ther isn't Log4J jar file in your project class path. For solve this exception add Log4J jar file to ypur project class path.
download Log4J jar file from : http://logging.apache.org/log4j/1.2/download.html
