NoClassDefFoundError :org/apache/regexp/RE

[Michel Baily]

Hi,

Trying to work with the lastest release (0.7) I get the following error when clicking on "New Enting" :

java.lang.NoClassDefFoundError: org/apache/regexp/RE
at com.robrohan.fangorn.Ent.buildXMLTools(Ent.java:285)
at com.robrohan.fangorn.Fangorn$11.run(Fangorn.java:217)

Do you have an idea on what I'm doing wrong ?

Best regards,

Michel

Hi Michel,
You are missing the Regular Expression library. It
sounds like you didn't use one of the installer
versions.

There are several version you can download (and little
explanation - sorry about that)

The ones that are OS specific (that end in _linux
_macosx _windows) have all the libraries needed to run
treebeard - also the one that says _java is a platform
independent installer. The just_treebeard is for
developers who want to forgo the download but know
about all the libraries.

Treebeard needs quite a few libraries to function
correctly (you can see a list here
http://sourceforge.net/project/shownotes.php?release_id=116790\)

I recommend you try one of the installer versions (if
you already did please let me know)

Thanks,
Rob

Same here.

I wanted to give Treebeard a try and installed
treebeard_v07_Linux.bin, run with:
java -jar treebeard.jar and after creating new
Enting I get the following:

java.lang.NoClassDefFoundError: org/apache/regexp/RE
    at com.robrohan.fangorn.Ent.buildXMLTools(Ent.java:285)
    at com.robrohan.fangorn.Fangorn$11.run(Fangorn.java:217)

Sincerely,
Sasa

Same thing as the last post, you are missing the Regular expression library. Your gig is a bit different as you have it on the system, but you are not including it in your run command.

Since you did use the installer, look in the Treebeard directory and run the .sh file in there that should have the command created correctly. Or if you want to run it from the command line like how you are trying you need to specify the classpaths to the Treebeard libs

java -classpath /path/regexp.jar:  etc etc  -jar Treebeard.jar

where etc etc is all the files in the install directory. But It's easier to just run the startup program that comes with treebeard.

Cheers,
Rob

Hi Rob!

Thanks for the reply.

I didn't realize that the link name is Fangorn :-(

Now, eeverything is OK.
