/usr/bin/java not found when dumping assetic

Question

I ran php app/console assetic:dump to publish assetics for a Symfony2 application, but I got this error:

[Assetic\Exception\FilterException]
  An error occurred while running:
  '/usr/bin/java' '-jar' '/home/devx/public_html/mutualcontratos/app/Resources/java/yuicompressor-2.4.7.jar' '--charset' 'UTF-8' '-o' '/tmp/YUI-OUT-3E8eNl' '--type' 'js' '/tmp/YUI-IN-DmkGnm'

  Error Output:
  sh: /usr/bin/java: No existe el fichero o el directorio

That means that java executable could not be found.

The fact is that I have another Symfony2 app on the same server and it works there. I compared both config.yml files and they are identical. What is missing in this other app?

This is the full config.xml file:

    - { resource: parameters.yml }

Answer 1

That is strange.... java does not exist in that folder... however, I have another symfony2 site in the same server and it works. I really don't know what assetic is doing to publish assets.
