TIBCO BW Functions

XPath Builder can be used to fetch process related information for any activity. These functions are listed under the TIBCO BW Functions group.

  • getModuleProperty: Returns the value of a module property. Also see TIBCO BW Predefined Module Properties under the Constants section.
  • getSystemProperty: Returns the value of a Java system property.
  • generateEPR: Returns an 'Endpoint Reference' as a string. This value can be used as an input to the Set EPR activity.
  • getHostName: Returns host name of the host machine.
Note: The XPath function xsd:string() saves double values in scientific notation if the double value has 7 or more digits before the decimal point. For example, if the value is 1000000.333, the xsd:string() function renders the value as 1.000000333E6.
