Beyond Core LotusScript®
This chapter discusses the role that LotusScript® plays with IBM® products, your operating environment, other programs, and interactive user applications.
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.
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.
JavaClass class (LotusScript® Language)
JavaClass is the reference to a Java™ class. You can create an instance of the object, or you can look at the static properties (fields) and invoke static methods of the class.
getClassProperties method (LotusScript® Language)
This method returns a list of properties.

  - Beyond Core LotusScript®
    This chapter discusses the role that LotusScript® plays with IBM® products, your operating environment, other programs, and interactive user applications.
    - IBM® software environments
      IBM® software provides the environment in which you create, debug, and run LotusScript® modules. IBM software applications that work with LotusScript supply their own application programming interface (API), which lets you use product functionality and create and manipulate product objects from within a LotusScript program. A IBM software API is effectively an extension to the LotusScript language that is available when you are running that product.
    - Interacting with the user
      IBM® products lend themselves to building interactive applications, applications that incorporate user input and prompt the user to perform particular tasks. While each individual IBM software application provides its own user interface for interacting with scripts, LotusScript® supplies some fundamental tools that you can use with any IBM software.
    - Interacting with other programs
      LotusScript® provides a number of functions and statements that you can use to interact with other programs and the operating system. You can also use Object Linking and Embedding (OLE) to incorporate functionality and data from other Windows™ applications into your LotusScript applications.
    - Calling external C language functions
      LotusScript® allows you to call external C language functions. You implement external C functions inside a named library module that generally contains several C functions. With Windows™, this is a Dynamic Link Library (DLL). All Windows users have access to the libraries in the Windows application programming interface (API).
    - 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.
      - 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.
        JavaClass class (LotusScript® Language)
        JavaClass is the reference to a Java™ class. You can create an instance of the object, or you can look at the static properties (fields) and invoke static methods of the class.
        Example: JavaClass class
        This script gets the Java™ class "Java.lang.Integer" and creates an object of that class in LotusScript®.
        ClassName property (LotusScript® Language)
        This property is the name of the JavaClass object. The property is read only.
        CreateObject method (LotusScript® Language)
        This method creates a JavaObject instance base of the JavaClass object.
        getClassMethods method (LotusScript® Language)
        This method returns a list of methods.
        getClassProperties method (LotusScript® Language)
        This method returns a list of properties.
        Example: getClassProperties method
        This script prints out all the available public properties belonging to the java.lang.Integer class.
        GetMethod method (LotusScript® Language)
        This method returns a method from a JavaClass object.
        GetProperty method (LotusScript® Language)
        This method returns a property.
        JavaError class (LotusScript® Language)
        JavaError is the main interface for LotusScript® to get information about Java™ errors that occur. Besides the standard exceptions mentioned in each object, the Java program can raise an exception for many other reasons. All these errors are caught and re-raised as the LotusScript Error-JavaError. Users can put an "on error" condition to catch any Java exceptions. The JavaException is not cleared until the method ClearJavaException is called. In order to find out more, the LotusScript user uses the JavaError object.
        JavaMethod class (LotusScript® Language)
        The JavaMethod class describes a public method in a JavaClass object. This class is used when the dot reference method fails (as happens with case sensitivity, method overloading, or long names).
        JavaMethodCollection class (LotusScript® Language)
        The JavaMethodCollection class enumerates all the methods of a JavaClass object. This is a true enumerator class and you can use the ForAll statement on it.
        JavaObject class (LotusScript® Language)
        The JavaObject Reference is the key to connecting with a Java™ object. It is returned from the CreateObject method of the JavaClass class or the GetJavaObject function. It is similar to an OLE reference and represents a Java object instance. The properties and methods are adapted automatically. It can be assigned only to a Variant.
        JavaProperty class (LotusScript® Language)
        The JavaProperty class describes a public property in a JavaClass object. This class is used for instances when the dot reference method fails (because of case sensitivity or long names).
        JavaPropertyCollection class (LotusScript® Language)
        The JavaPropertyCollection class enumerates all the properties of a JavaClass object. This is a true enumerator class and you can use the ForAll statement with it.
        JavaSession class (LotusScript® Language)
        JavaSession is the starting point for access to the Java™ objects. The session attaches to the existing JVM, if there is one. If a JVM has not been started, the LotusScript® client tries to create the JVM and apply all the specified arguments. You can create as many JavaSessions as you want. All the resources created are associated with a particular session. Delete the session object to reclaim the resources.
      - 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.
