Some issues on building the compiled version of the MATLAB code

Reading config files (m files using eval)

When reading/writing files - such as config files - not everything will behave like in the matlab console.

The way the config files were being read was not working - was simply using eval. It was necessary to read the file manually, adapting the suggestion found here:

(...)in a function we would create a text file, INP, containing our parameters.
We create this file in the directory returned by the ctfroot function.
Then, in MAIN, we would use the following to retrieve these parameters:

  eval(char(textread(fullfile(ctfroot, INP), '%s', 'whitespace', '');

See commit:d9262cdbfb38d9262cdbfb38 on the jabuilder-int branch.

Other input/output files

At the moment the input/output is done in the same folder where the the java class is being called from (hrir_final.mat and binsimecho.wav...).

Building the isvr jar

The app configuration file can be found in webapp/WEB-INF/classes/


We are using log4j for logging. The log4j jar (1.2.17) is included in the repository. The configuration file is in webapp/WEB-INF/classes/
