Can Tomcat 4.0 be used with webMathematica?

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.

http://support.wolfram.com/archive/webmathematica/files/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

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.
