Re: JESS: Newbie Problem running Jess

Well, I am back.   This time I am going through the examples in the manual using either the cmd prompt or JessWin and in each case the examples get various errors.   Example,   At the Jess> prompt in the command prompt window I type (there is no "sticks" example in my examples folder as the manual says there is)   (batch examples\fullmab.clp)   and I also try   (batch \Jess61p6\examples\fullmab.clp)   and always get a response like:   Jess reported an error in routine batch while executing (batch \Jess61p6\examplesfullmab.clp) at line 1. Nested exception is: \jess61p6examplesfullmab.clp (The system cannot find the file specified)   along with a java stack trace.   Not that the backslash is missing from the reported line: examplesfullmab versus what I typed: examples\fullmab   When type java -classpath jess.jar jess.Main examples/fullmab.clp into the JessEditor and send to JessWin I get   Jess> java -classpath jess.jar jess.Main examples/fullmab.clp java Jess> -classpath Jess> jess.jar Jess> jess.Main Jess> examples/fullmab.clp   and nothing else happens anywhere on the screen.     I tried several of the examples and all give the same result.       thoughts?   Is there a proven step by step tutorial out there that leads one through the steps in this?         ----- Original Message ----- From: Michael Knapik To: [EMAIL PROTECTED] Sent: Wednesday, March 24, 2004 11:36 AM Subject: Re: JESS: Newbie Problem running Jess Understood. I fixed the path and CLASSPATH vars. The book instructions and where the download ended up were a bit different. I should have noticed.   I also installed Jess and got it running.   Thanks all  I presume I will be asking more questions as I continue learning this app as it will be my primary app I use in my new job!   Thanks for the patience!   Mike   ----- Original Message ----- From: Robert Brown To: [EMAIL PROTECTED] Sent: Wednesday, March 24, 2004 10:56 AM Subject: RE: JESS: Newbie Problem running Jess Try the whole relative path or ensure you are in the directory where Jess is installed.   I created a batch file to save me the headache and named it jess.bat   @echo off java -classpath d:\download\jessse\jess61p4\jess.jar jess.Main %1   Now I can run from anywhere.   Good luck -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Michael Knapik Sent: Wednesday, March 24, 2004 11:32 AM To: [EMAIL PROTECTED] Subject: JESS: Newbie Problem running Jess I downloaded and unpacked Jess to C:\Jess.   I have the recent java SDK from Sun installed in c:\j2sdk1.4.2_04   I am running XP Pro.   I added the path info in your book (;.;C:\Jess61\jess.jar) to both the Path system variable, the Path User Variable and a new CLASSPATH user variable.   I opened the CommandPrompt and cd'd to C: and tried to execute java jess.Main and got:   Exception in thread "main" java.lang.NoClassDefFoundError: jess/Main   instead of the welcome banner etc.   Thoughts?   Mike
