org.openbp.server.engine.script.ScriptEngine.executeScript()
Exeuctes a script. Uses the Bean Shell interpreter to perform the evaluation. @param script Script to execute @param fileType Textual description of the type of file that contains the script (see 'fileName' parameter) @param fileName Name of the object containing the script (e. g. a file name or a qualified model object name) @return The value of the last expression in the script or null if the expression value itselfis null or the script did not return a valid value @throws OpenBPException On syntactical or semantical errors
