    Basic product usage information and programming language reference information.

  3. LotusScript® Language

    Welcome to the LotusScript® Language section of Domino® Designer Help.

  4. Beyond Core LotusScript®

    This chapter discusses the role that LotusScript® plays with IBM® products, your operating environment, other programs, and interactive user applications.

  5. 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.

  6. 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.

  7. 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).

      • 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.

            • 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).

              • Example: JavaMethod class

                This script prints out the number of toString methods belonging to the java.lang.Integer class.

              • JClass property (JavaMethod - LotusScript® Language)

                This property is a JavaClass object representing the JavaClass object in which the method belongs. The property is read only.

              • MethodName property (LotusScript® Language)

                This property contains the name of the method. This property is read only.

              • Modifier property (JavaMethod - LotusScript® Language)

                This returns the modifier value(s) for a Java™ method. The property is read only.

              • Signature property (LotusScript® Language)

                This property is the JNI signature representing the method arguments and return value. The property is read only.

              • Invoke method (LotusScript® Language)

                This method executes a method.

            • 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.

      • LotusScript® Language Reference

        This chapter describes the use of statements, built-in functions, subs, data types, and directives in the LotusScript® language.

      • Language and Script Limits

        This appendix describes LotusScript® language limits of several kinds: for example, the legal ranges in data representation, the limits on numerical specifications within statements, and the maximum number of different kinds of elements that can be defined in a script.

      • Platform Differences

        The LotusScript® language and functionality on the UNIX™ platform, the Macintosh platform, and the OS/400® platform differ in various ways from the language and functionality described in the rest of this language reference. This appendix describes the differences.

      • LotusScript/REXX Integration

        This appendix provides an overview of REXX integration in the LotusScript® language.
