title: LibGDX : HTML5 not finding shaders
body: <p>I have written a LibGDX 3D project which works perfectly on Android, iOS and Desktop however when I run it in the browser, it cant find the shader files.  It can find all other files.  If I copy the shader files in to 2 strings instead it works fine also.</p>
  
  <p>I load shaders like this</p>
  
  <pre><code>vertexShader = Gdx.files.internal("vertex.glsl").readString();
  fragmentShader = Gdx.files.internal("fragment.glsl").readString();
  shaderProgram = new ShaderProgram(vertexShader,fragmentShader);
  </code></pre>
  
  <p>I have restarted the GWT server, cleaned, recompiled etc!</p>
