Petite Abeille

The following solution is more involved than what is strictly needed. It may avoid the debug message, he is using some quasi-private stuff.

It can be quite easy

Code Block
protected WOElement myTemplate = null;
public WOElement template() {
  if ( myTemplate == null ) {
      myTemplate = WOComponent.templateWithHTMLString( html, wod, null );
  }
  return myTemplate;
}

A More Involved Solution:

Here is a little example on how to overwrite WOComponent.template() so
you can load the html template and wod from wherever you want )eg a jar
file):

  • First you will need to overwrite WOComponent.template()
Code Block
public WOElement template() {
  return Component.templateForComponent( this );
}
  • Now, templateForComponent could look like this:
Code Block
public static WOElement templateForComponent(WOComponent aComponent) {
if ( aComponent != null ){
  String aName = aComponent.name();
  WOElement anElement = (WOElement) _elementCache.get( aName );
  if ( anElement == null ) {
    String anHTMLString = Component.componentTemplateWithExtension( aComponent, ".html" );
    String aDescriptionString = Component.componentTemplateWithExtension( aComponent, ".wod" );
    anElement = WOComponent.templateWithHTMLString ( anHTMLString, aDescriptionString, null );
    if ( aComponent.isCachingEnabled() == true ) {
      _elementCache.put( aName, anElement );
    }
  }
  return anElement;
}
throw new IllegalArgumentException ( "Component.templateForComponent: null component." );
}
  • The componentTemplateWithExtension method could look like the following:
Code Block
private static String componentTemplateWithExtension(WOComponent aComponent, String anExtension) {
if ( anExtension != null ) {
  String aResource = aComponent.name() + anExtension;
  InputStream anInputStream = Component.componentStreamForResource( aComponent, aResource );
  if ( anInputStream != null ) {
    StringBuffer aBuffer = new StringBuffer();
    try {
      BufferedInputStream  aBufferedStream = new BufferedInputStream( anInputStream );
      InputStreamReader  aStreamReader = new InputStreamReader( aBufferedStream );
      int aChar = -1;
      while ( ( aChar = aStreamReader.read() ) != -1 ) {
        aBuffer.append( (char) aChar );
      }
        anInputStream.close();
      } catch(Exception anException) {
        Log.warning( anException );
      }
      return aBuffer.toString();
    }
    throw new RuntimeException ( "Component.componentTemplateWithExtension: resource not found: '" +  aResource + "'." );
  }
}
throw new IllegalArgumentException ( "Component.componentTemplateWithExtension: null extension." );
}
  • And finally componentStreamForResource could be something along these:
Code Block
private static InputStream componentStreamForResource(WOComponent aComponent, String aResource) {
if ( aResource != null ) {
  File aDirectory = new File( System.getProperty( "user.dir" ) );
  File aFile = new File( aDirectory, aResource );
  if ( aFile.exists() == true ) {
    try {
      return new FileInputStream( aFile );
    } catch(Exception anException) {
      Log.warning( anException);
    }
  }
  return aComponent.getClass().getResourceAsStream( aResource );
}
throw new IllegalArgumentException( "Component.componentStreamForResource: null resource." );
}
