And it also works fine for 10.1 by adding these lines to MSPConfiguration.xml :

Windows:

<KernelExecutable>
        C:\Program Files\Wolfram Research\Mathematica\10.1\MathKernel.exe
</KernelExecutable>

<FrontEndExecutable>
        C:\Program Files\Wolfram Research\Mathematica\10.1\Mathematica.exe
</FrontEndExecutable>

Linux:

<KernelExecutable>
      /usr/local/Wolfram/Mathematica/10.1/Executables/MathKernel
</KernelExecutable>

<FrontEndExecutable>
      /usr/local/Wolfram/Mathematica/10.1/Executables/Mathematica
</FrontEndExecutable>

Our documentation for webM installation for Linux can be found here:

Here are some things that I've found to be quite useful:

1. give the tomcat user a shell. That way, you can log in to your machine as that user and test things out yourself. Some possible issues that you can uncover this way are mathpass file issues and front end issues\
2. As Rodrigo says, the FrontEnd needs to work in order for any images (plots included) to be generated. So you need to allow the tomcat user to have access to a display. I'd recommend using a vncserver for this. You will need to set the FrontEndLaunch flags in our MSPConfiguration.xml file. We have examples in the documentation; my setting is "-display chadsLinux:1 -nogui -geometry 1000x500+24+24".
3. For testing purposes, try logging in to a terminal as the tomcat user and launching Mathematica in your vnc display. At the terminal prompt, type '\path\to\Mathematica -display [your machine]:[the display number]'. In a vncviewer set to that display, check to see that it launched correctly. Try some evaluations in a notebook
4. Tomcat setup is really the key issue for installation. I've found that default installations using apt-get (Ubuntu) and yum (Red Hat) both work nicely. If you have never used tomcat previously, those are a great starting point.

If you have any other questions, please contact our tech support. Have fun!

I don't have the steps, but I have success in make it work in RedHat. It was not easy to make front end to work. Front end instance is needed for make plots or file export to work.

I'm very glad to hear that it works, Roberto!

Could you share the version of Windows that you're using?

Nice!... One more WebMathematica in V10.

I can't remember what the exact memory usage of the front end is. It may be slightly greater than 1024 (I left my 3rd entry blank).

One dumb question for you: did you reboot the machine after editing the registry?

Another possible issue is the JLink native directory. You can try specifying it explicitly (make sure to edit if you have a different location:

<JLinkNativeLibraryDirectory>
C:\Program Files\Wolfram Research\Mathematica\10.0\SystemFiles\Links\JLink\SystemFiles\Libraries\Windows-x86-64
</JLinkNativeLibraryDirectory>

No, it want to work! Any further suggestion?

Yes. For Windows I did this to make de V10 kernel to work:

1. First install Mathematica 9
2. Make WebMathematica work on 9
3. Install version 10 and redirect to Mathematica 10 kernel in MSPConfiguration.xml file.
4. If last step work, now you can uninstall version 9.

And then, to make Graphics work (front end dependent expressions), I need to change windows regedit.

PS: in MAC, it didn't worked with JAVA 8, I needed to downgrade into java 7.

Mathematica 10 is not officially supported by webMathematica, but it can be made to work reasonably well.

Roberto, I'm guessing that you are using a Windows machine? If that's true, then the problem is that Mathematica 10's front end uses more memory than allowed by the default desktop heap setting for noninteractive users.

You can read more about it here: [http://support.microsoft.com/kb/2102398][1]

The short answer is that you can edit the registry to increase this value. Then the front end should work fine in webM.

Hi Rodrigo, are you working with webMathematica and Math10? I'm not able to run it. For each example in the documentation I get the following error: FrontEndError: ExportString failed:\

Notebook[{Cell[BoxData[RowBox[{FractionBox[x, 2], -,\

RowBox[{FractionBox[1, 4], , RowBox[{Sin, [, RowBox[{2, , x}],\

]}]}]}]], Output, ShowCellBracket -> False, CellMargins -> {{0, 0}, {0,\

0}}, PageWidth -> 800]}, WindowSize -> 900]

I changed the configuration file adding the path to Mathematica 10.0 and it works, indeed the following "< msp:evaluate >$Version< /msp:evaluate >" works fine. Please, let me know if you have any hint. Thanks in advance. Roberto
