[Attempto] need help getting ACE Wiki running

[Murray, William R]

Tobias --

OK, I'm still getting there. I've figured out the following:

1. To compile ape.exe I use SWI-Prolog to build it, as opposed
to Java. I created it successfully.

2. I found jpl.dll hiding in C:\Program Files\SWI-Prolog\bin,
and so added that path to my PATH environment variable.

However, now when I start Tomcat 5.0 a dialog box comes up that
taunts me with,

"Windows cannot find '-Djava.endorsed.dirs='. Make sure you typed that name correctly, and then try again. To search for a file, click the Start a button, and then click Search."

...and in the command window (cmd.exe) I get these error messages:

The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE
Using CATALINA_BASE: C:\Program Files\Apache Software Foundation\Tomcat 5.0
Using CATALINA_HOME: C:\Program Files\Apache Software Foundation\Tomcat 5.0
Using CATALINA_TMPDIR: C:\Program Files\Apache Software Foundation\Tomcat 5.0\temp
Using JAVA_HOME: C:\jdk1.6.0_13

So currently I have two questions:

1.	What causes the problem(s) when I try to launch Tomcat? Are my environment variables just set up wrong...it used to work.
2.	I didn't understand what you meant in the sentence "This can be done by a Java VM argument like this:

   -Djava.library.path=/opt/local/lib/swipl-5.6.45/lib/i386-darwin8.10.1

    " since I can understand how I would do that if were calling a class 
     with the java interpreter, but we're doing something different, we're
     starting Tomcat. The best I can interpret this is that I have to modify
     the catalina.bat file to somewhere add this as I can't see where to do
     this in the startup.bat file...what am I missing?

   --Tnx!
         Bill

P.S. If some of this is plain old Java config problems I can get a sysadmin to sort those out, I'm just not sure which are those and which are related to Tomcat or AceWiki now.

Hi Bill,

Ok, we are getting closer and closer.

Check the files "logs/localhost.*.log" in your tomcat directory. Probably you have an error message 
there that says "java.lang.UnsatisfiedLinkError: no jpl in java.library.path".

You need to have a recent version of SWI Prolog installed and you have to make sure that the file 
"jpl.dll" is found by Java. This can be done by a Java VM argument like this:

   -Djava.library.path=/opt/local/lib/swipl-5.6.45/lib/i386-darwin8.10.1

The detailed instructions can be found here:

   http://attempto.ifi.uzh.ch/site/docs/java/README.txt

Furthermore, you have to download and build APE:

   http://attempto.ifi.uzh.ch/site/downloads/files/ape-6.5-090616.zip

You have to make sure that the resulting "ape.exe" can be found. Copying it to the tomcat home 
directory should work.
