Re: WOInstaller.jar throws Exception in thread "main" java.io.IOException: Cannot run program "/bin/ln"

Re: WOInstaller.jar throws Exception in thread "main" java.io.IOException: Cannot run program "/bin/ln"

The hard link count of your /bin/ln is 1. It should be 2, since /bin/link and /bin/ln point to the same file (at least on 10.8). Do you have /bin/link?

Hi All,

I am installing WOFramework using the following:

$ sudo mkdir -p /Library/WebObjects/Versions/WebObjects543
$ curl -O http://wocommunity.org/tools/WOInstaller.jar
$ sudo java -jar WOInstaller.jar 5.4.3 /Library/WebObjects/Versions/WebObjects543

I am following the installer on the following link:

http://wiki.wocommunity.org/display/WEB/Project+Wonder+Installation

mkdir works

getting the JAR works

but unlike the video on the installer page, running the installer throws the following exception:

tpeterss-macbook-pro-15:eclipse thomasgpeters$ sudo java -jar WOInstaller.jar 5.4.3 /Library/WebObjects/Versions/WebObjects543
Downloading WebObjects: Done

I am running the installer from sudo, but it is still causing this error.  Any help appreciated.

Thomas
