Beta Draft
This chapter describes how to use the demonstration program designed for Oracle COM Automation Feature for Java.
This chapter contains these topics:
Oracle COM Automation Feature for Java includes an example that demonstrates how to use the feature to build solutions. The demo provides base functionality and can serve as a foundation on which to build more customized, complex applications that use COM Automation. This demo is based on the human resources schema available with the sample schema.
The demo exposes a core set of APIs that enable you to do simple operations using COM Automation Feature. Each COM Automation server, such as Word and Excel, provides more advanced capabilities than what is offered through the demo APIs. To take advantage of these advanced features, you must design and code your own Java classes.
In this release, COM Automation has provided the Microsoft Word Java Demo, which exchanges data between Oracle Database instance and Word.
The following sections describe how to install the Microsoft Word Java demo and the APIs that it exposes. This demo is provided as an example of the types of solutions that can be built with Oracle and Microsoft Word.
The demo creates a Microsoft Word document containing the names of employees in the database.
The Microsoft Word Java demo is installed in the ORACLE_BASE\ORACLE_HOME\com\java\demos directory and provides the following:
TestWORD.java, the Java source for the demo. In addition to the collection of APIs, it includes the demo program test.
TestWORD.sql, the script which creates the call spec for the demo.
Microsoft Word must be installed on the local computer before installing this demo.
To install the demo:
Run loadjava from the command line:
loadjava -force -resolve -user hr/hr ORACLE_BASE\ORACLE_HOME\com\java\demos\TestWORD.class
Start SQL*Plus.
C:\> sqlplus /NOLOG
Connect to the Oracle database instance as the user who will use the Microsoft Word demo. For example:
SQL> connect hr/hr
Run TestWORD.sql to create the call spec:
SQL> @ORACLE_BASE\ORACLE_HOME\com\java\demos\TestWORD.sql
|
See Also: Oracle Database Java Developer's Guide for further information on theloadjava tool and call specs |
To use the Word demo:
Set SERVEROUTPUT on at the SQL*Plus prompt:
SQL> SET SERVEROUTPUT ON
Call TestWORD() at the SQL*Plus prompt:
SQL> CALL TestWORD();
This creates a Microsoft Word document (worddemoj.doc) in the C:\directory. The document contains data from the EMPLOYEES and JOBS tables. These tables are available in the human resources schema in the sample schema.
The public class TestWORD API as described in "Core Functionality" , provides a wrapper around the Word.Basic COM Automation class as well as some sample code which demonstrates how to use the wrapper. This code was written to be run on the Oracle database server.
To create a custom application which uses this wrapper:
Instantiate an object of this class.
Create the Word.Basic object by calling the CreateWordObject method.
Create a new Microsoft Word document with the FileNew method, or open an existing document with the method FileLoad.
Use the FormatFontSize, InsertText, InsertNewLine methods to add text and formatting to the document.
Save the document with FileSaveAs or FileSave method.
Call the FileClose method when you are finished with the document.
Call the DestroyWordObject method when you are finished with the Word.Basic object.
The following subsections describe the APIs that the Microsoft Word Java demo exposes. These APIs are primitive. Be aware that much of the functionality that Microsoft Word exposes through COM Automation is not exposed through these APIs.
TestWORD
This API is the constructor. It does nothing.
Syntax
public TestWORD()
CreateWordObject
Creates the Word.Basic COM object.
Syntax
public void CreateWordObject(java.lang.String servername)
| Where | Is |
|---|---|
| servername | the server on which to create the COM object. Specify null or the empty string for the local server. |
DestroyWordObject
This API destroys the Word.Basic COM object.
Syntax
public void DestroyWordObject()
FileNew
This API creates a new Microsoft WORD document.
Syntax
public void FileNew()
Remarks
Wrapper for the FileNewDefault COM method of the Word.Basic COM object.
FileLoad
This API loads an existing Microsoft WORD document.
Syntax
public void FileLoad(java.lang.String filename)
| Where | Is |
|---|---|
filename |
the name of the file to load. |
Remarks
Wrapper for the FileOpen COM method of the Word.Basic COM object.
FormatFontSize
This API sets the font size.
Syntax
public void FormatFontSize(long fontsize)
| Where | Is |
|---|---|
fontsize |
the new font size. |
Remarks
Wrapper for the FormatFont COM method of the Word.Basic COM object.
InsertText
This API inserts text into the Microsoft Word document.
Syntax
public void InsertText(java.lang.String textstr)
| Where | Is |
|---|---|
textstr |
the text to insert. |
Remarks
Wrapper for the Insert COM method of the Word.Basic COM object.
InsertNewLine
This API inserts a newline into the Microsoft Word document.
Syntax
public void InsertNewLine()
Remarks
Wrapper for the InsertPara COM method of the Word.Basic COM object.
FileSaveAs
This API saves the Microsoft Word document using a specified name.
Syntax
public void FileSaveAs(java.lang.String filename)
| Where | Is |
|---|---|
filename |
the name of the file. |
Remarks
Wrapper for the FileSaveAs COM method of the Word.Basic COM object.
FileSave
This API saves the Microsoft Word document.
Syntax
public void FileSave()
Remarks
Wrapper for the FileSave COM method of the Word.Basic COM object.
FileClose
This API closes the Microsoft Word document, and exits Microsoft Word.
Syntax
public void FileClose()
Remarks
Wrapper for the FileClose and FileExit COM methods of the Word.Basic COM object.
