Hi everyone, We too had similar problem with webMathematica ( as in following link) http://forums.wolfram.com/mathgroup/archive/2003/Jan/msg00035.html Finally we got around with the problem. Here with i'm including the mail from Technical Support of Wolfram Research, Inc. But they forgot to mention something important. After you have followed their instructions and moved jlink.jar and JLinkNativeLibrary.dll to: webMathematica/WEB-INF/lib (in tomcat webapps directory) You have add this path to your CLASSPATH. CLASSPATH=%CLASSPATH%;C:\Program Files\Apache Group\Tomcat 4.1\webapps\webMathematica\WEB-INF\lib; Hope that helps Thank you, Jai Bharat Patel -----Original Message----- From: support at wolfram.com [mailto:support at wolfram.com] To: mathgroup at smc.vnet.net Subject: [mg39746] [TS 4129]--Re:[Phone 468] Hello Mr. White, Thank you for the phone call. There are two files that need to be moved from the Mathematica layout to within tomcat's directory structure. C:\Program Files\Wolfram Research\Mathematica\AddOns\JLink\jlink.jar C:\Program Files\Wolfram Research\Mathematica\AddOns\JLink\System Files\Libraries\Windows\JLinkNativeLibrary.dll Both need to be moved to: webMathematica/WEB-INF/lib The following FAQ is also required to get webmathematica working under Tomcat 4.0 or later. The following information is also available from the Technical Support section of our website at the following URL: http://support.wolfram.com/webmathematica/installation/preinstallation/t omcat40.html Tomcat 4.0 can be used as a servlet container for webMathematica. To do so, it is necessary to update your web.xml file, and obtain a new version of J/Link. 1) Obtain the new web.xml file. We have provided updated web.xml files for both the Windows and Linux/Solaris platforms that work with Tomcat 4.0. web.xml.nt web.xml.unix Once you have downloaded the appropriate web.xml file, remove the .nt or .unix extension and place it in the corresponding Tomcat folder. Windows C:\Program Files\Apache Tomcat 4.0\webapps\webMathematica\WEB-INF Linux/Solaris /usr/local/tomcat/webapps/webMathematica/WEB-INF 2) Obtain the new J/Link distribution. If you do not update your version of J/Link then Java Object References will not work correctly. For more advanced webMathematica web-sites, these are an important and powerful extension mechanism. Basic webMathematica sites for calculating and plotting will work correctly with the version of J/Link that ships with webMathematica. You can download J/Link 2.0 beta from http://www.wolfram.com/solutions/mathlink/jlink/ This can be unpacked and then installed into the appropriate Mathematica application. Windows C:\Program Files\Wolfram Research\Mathematica\4.1\AddOns\Applications Linux/Solaris /usr/local/mathematica/AddOns/Applications In order to make the J/Link classes available to Tomcat you need to copy the JLink.jar file and the SystemFiles directory into the webMathematica layout. Windows C:\Program Files\Apache Tomcat 4.0\webapps\webMathematica\WEB-INF\lib Linux/Solaris /usr/local/tomcat/webapps/webMathematica/WEB-INF/lib This is a sufficient installation for J/Link. After this webMathematica should be able to run correctly with Tomcat 4.0.
