Does the Java Object return type force us into #PeopleCode/Java reflection misery? Can you cast Java Objects in PeopleCode? #PeopleSoft has fantastic built-in support for Java. Sometimes, figuring out how to translate between the two languages can be challenging. In this episode, we use CreateJavaObject and GetJavaClass to extend the PeopleCode API with Java and discuss how modern Java Generics affect our PeopleCode. • Sample PeopleCode: • Local JavaObject map = CreateJavaObject( java.util.HashMap ); • map.put( Key 1 , CreateJavaObject( java.lang.String , This is a string )); • Local JavaObject result = map.get( Key 1 ); • /* • Local JavaObject stringClass = GetJavaClass( java.lang.Class ).forName( java.lang.String ); • Local JavaObject newString = stringClass.cast( result); • */ • Local JavaObject newString = result.getClass().cast( result); • MessageBox(0, , 0, 0, %1 , newString.charAt(2)); • MessageBox(0, , 0, 0, %1 , result.toString()); • • Jim Marion is an #OracleAce ♠, author of several PeopleTools books, blogger, public speaker, and PeopleTools instructor.
