Trouble installing Juxta Beta Dana Wheeles 4/17/12 12:28 PM
Some users a running into difficulties related to having old and incompatible versions of a java xml parsing file --such as xerces.jar -- on their computers. If you see an installation error that looks something like the one below, then we have a fix for you.


To verify that this is the case, open up a Terminal window and type:
ls /Library/Java/Extensions

If there is something like xerces.jar listed there, it will need to be move someplace else. For now, the desktop is a good place. Move it by entering the command:
mv /Library/Java/Extensions/xerces.jar ~/Desktop/

If the file is not present at the location mentioned above, try the same steps as above, but using the path ~/Library/Java/Extensions instead.

Once this has been done, retry the installer.
