I had the following error in a « User Defined Java Class » step on Pentaho Data Integration.

FieldHelper cannot be cast to java.lang.String

Indeed, you have to use the getRow() method to convert the field you’re getting into a String or any other variable type.

public boolean processRow(StepMetaInterface smi, StepDataInterface sdi) throws KettleException, Exception
{
  Object[] r = getRow();
        if (r == null) { return false; }
        String myString = get(Fields.In, "FeedSubmissionId").getString(r);
}

👴 Attention Cet article a quelques années et n’est peut-être plus à jour !

When I was installing the bluetooth library, i was told to type the directory where Java Interpreter was installed.

Run the command:

  which java

It’s gonna answer you « /usr/bin/java », type only « /usr/bin » in the shell line and you’re good 🙂 (Mac OS X Lion)
