Class FormProcessor

java.lang.Object
oracle.apps.xdo.template.FormProcessor

public class FormProcessor

extends java.lang.Object

The class FormProcessor is the entry class to merge data with an original template. Also, you can use this class from the command line. The following is a basic usage of FormProcessor.

  FormProcessor formProcessor = new FormProcessor();
  formProcessor.setTemplate(original_pdf_file_path); // or formProcessor.setTemplate(inputStream);
  formProcessor.setData(xfdf_file_path); // or formProcessor.setData(inputStream);
  formProcessor.setOutput(new_pdf_file_path); // or formProcessor.setOutput(outputStream);
  formProcessor.process();
 

The command line usage is following.

 java oracle.apps.xdo.template.FormProcessor <Template PDF file> <Data file> <Output file>

makeOutputFlat

public void makeOutputFlat(boolean flag)

Deprecated. since 5.6

FormProcessor takes care of two kind of processing.

1. The first one is to merge data into fields only.
2. The second thing is to process repeatable fields.

If the first one is processed, then an output keeps fields even though users can't modify it using browser.
The second output doesn't contain fields.
If output is required not to contain any fields, please call this method with true argument.

Parameters:

flag - true if output is required to be flat, false otherwise.

Sets the lov values for a combo box or list box.
The first vector passed in is an ordered vector of internal values. The second vector passed in sets the ordering of labels in the combo or list box. The last parameter specifies which internal value will get selected in the lov combo or list box. It maybe a String instance or Vector instance (for specifying of multiple selected values in the listbox case).
