Human Echolocation WebApp

h1. Deployment runthrough

This is an example deployment, on a 64-bit Linux host. There are various different ways to do this and the details will vary from one platform to another.

h2. 1. Obtain the current code from Mercurial repository

<pre>

$ hg clone https://code.soundsoftware.ac.uk/hg/human-echolocation-java-webapp

h2. 2. Install the MATLAB Compiler Runtime

Navigate to http://www.mathworks.co.uk/products/compiler/mcr/ and find the download URL, then use as follows.

<pre>

$ mkdir mcr

$ cd mcr

$ wget 'http://www.mathworks.co.uk/supportfiles/downloads/R2013b/deployment_files/R2013b/installers/glnxa64/MCR_R2013b_glnxa64_installer.zip'

$ ./install

</pre>

The installer window then pops up (X server connection required for graphical interaction here).

The default installation folder is @/usr/local/MATLAB/MATLAB_Compiler_Runtime@. I'm going to accept that.

The installer runs, and then prints out the following:

<pre>

On the target computer, append the following to your LD_LIBRARY_PATH environment variable:

/usr/local/MATLAB/MATLAB_Compiler_Runtime/v82/runtime/glnxa64:/usr/local/MATLAB/MATLAB_Compiler_Runtime/v82/bin/glnxa64:/usr/local/MATLAB/MATLAB_Compiler_Runtime/v82/sys/os/glnxa64:/usr/local/MATLAB/MATLAB_Compiler_Runtime/v82/sys/java/jre/glnxa64/jre/lib/amd64/native_threads:/usr/local/MATLAB/MATLAB_Compiler_Runtime/v82/sys/java/jre/glnxa64/jre/lib/amd64/server:/usr/local/MATLAB/MATLAB_Compiler_Runtime/v82/sys/java/jre/glnxa64/jre/lib/amd64

Next, set the XAPPLRESDIR environment variable to the following value:

/usr/local/MATLAB/MATLAB_Compiler_Runtime/v82/X11/app-defaults  

</pre>

h2. 3. Bring dependent JAR files into the webapp folder

Make sure we're back in the webapp folder (the one we cloned from Mercurial earlier)

<pre>

$ cd ../human-echolocation-java-webapp

</pre>

Copy in the Servlet API library from our application server (in this case Tomcat):

<pre>

$ cp /usr/share/java/tomcat7/servlet-api.jar .

</pre>

And the MATLAB MCR JavaBuilder library:

<pre>

$ cp /usr/local/MATLAB/MATLAB_Compiler_Runtime/v82/toolbox/javabuilder/jar/javabuilder.jar ./WebContent/WEB-INF/lib/

</pre>
