Custom activity sample code

The Java code in this section is a simple example of custom activity called StringBean, which is included with the Custom Activity SDK.

StringBean contains the following:

• Ten input properties, inString1 through inString10
• One output property, outputString
• Three action methods:
  • concatStrings, which concatenates inString1 through inString10 and puts the results in outputString
  • logStrings, which calls concatStrings and then outputs the results to the IPA logs using the BPMAdapterRuntime interface
  • stripTrailingLinefeedChars, which calls concatStrings then removes new line characters and puts the result in outputString
