com.ibm.as400.data
Class ProgramCallDocument

java.lang.Object
  com.ibm.as400.data.ProgramCallDocument

All Implemented Interfaces:: Serializable, Cloneable

public class ProgramCallDocument
extends Object
implements Serializable, Cloneable

XML Document based program call. The ProgramCallDocument class uses a Program Call Markup Language (PCML) document to call IBM i system programs. PCML is an XML language for describing the input and output parameters to the IBM i system program. This class parses a PCML document and allows the application to call IBM i system programs described in the PCML document.

Command Line Interface

The command line interface may be used to serialize PCML document definitions. Note that XPCML documents cannot be serialized.

 java com.ibm.as400.data.ProgramCallDocument
     -serialize
     PCML document name

Options:

-serialize: Parses the PCML document and creates a serialized version of the document. The name of the serialized file will match the document name, and the file extension will be .pcml.ser (lowercase).
PCML document name: The fully-qualified resource name of the PCML document which defines the program interface.

                          XmlException

Generates XPCML representing the data associated with the passed in program name. XPCML is XML based on the XML schema defined in xpcml.xsd. XPCML is similar to PCML but allows for better validation of parameters and allows parameter data to be input and output within an XML document. PCML is data-less in that only parameter formats are input via PCML. In PCML, data values are set using the setValue methods of the ProgramCallDocument class and data values are gotten using the getValue methods of ProgramCallDocument. In XPCML, data values can be input directly within the XPCML document on construction and data values can be output as XML using the generateXPCML method. Throws an XmlException if this object contains no data.

Parameters:: pgmName - The program to generate XPCML for; outputStream - The output stream to which to write the text.
Throws:: IOException - If an error occurs while writing the data.; XmlException - If an error occurs while processing XPCML.

                          XmlException

Generates XPCML representing the data contained in the entire PCML node tree. XPCML is XML based on the XML schema defined in xpcml.xsd. XPCML is similar to PCML but allows for better validation of parameters and allows parameter data to be input and output within an XML document. PCML is data-less in that only parameter formats are input via PCML. In PCML, data values are set using the setValue methods of the ProgramCallDocument class and data values are gotten using the getValue methods of ProgramCallDocument. In XPCML, data values can be input directly within the XPCML document on construction and data values can be output as XML using the generateXPCML method.
