LS2J: Connecting with Java

Using LotusScript® and LS2J, you can access Java classes, giving you a powerful cross-platform extension to LotusScript. Developers can access Java in LotusScript programs as a set of predefined LotusScript objects. This set of objects allow LotusScript to use already created Java classes that are available in script libraries or found using the classpath.

Note: This feature is new with Domino® Release 6.

About LS2J

LS2J extended example

About LS2J
LS2J is the interface that allows data to transfer from the Java data type to the LotusScript data type and allows LotusScript to execute Java object methods. LS2J allows LotusScript to create Java objects as if they are native to the LotusScript environment.
System requirements
LS2J is implemented on all Domino platforms. Your system must meet the following requirements:
Using LS2J
To use LS2J from within Notes, your LotusScript code must include this line:
LS2J classes
LS2J introduces the concept of a Java object reference. Similar to an OLE object reference, it is not a predefined class; rather, it represents a runtime instance of a Java object. Its properties and methods are determined at run time.
Data type mappings
LotusScript provides mapping for Java basic data types and Java reference types.
LS2J extended example
This sample code demonstrates calling Java methods within LotusScript using LS2J. Immediately following this example the code is modified slightly to demonstrate handling situations where there is a syntax discrepancy between Java and LotusScript.
