I/O, I/O, It's off to work we go By Vinod Ravi

Introduction

webMethods Integration Server v4.6 includes only one I/O service in its WmRoot package -- pub.file:getFile.

The notable absence of built-in I/O services is justified because of security concerns, but there are many cases in which additional I/O services are required for routine business integration tasks.

This webMethods Ezine article discusses the attached package and how a webMethods Developer can deploy it to add I/O functionality to their Integration Server.

Note: The package requires JDK 1.1.8 or higher.

Package Overview

The Utilities package contains two subfolders:

1. FileIOUtilities -- Java services for reading from and writing to a file server
2. GeneralUtilities -- Java services which support the FileIOUtilities services

FileIOUtilities contains the following I/O services:

• deleteFile -- Deletes a file from a file server
• directoryCleaner -- Removes (and optionally backs up) old files from a file server
• getProperties -- Reads properties from a properties file on a file server
• listDirectory -- Returns all files residing in a directory on a file server
• writeToLog -- Writes a string to a file on the fle server

GeneralUtilities contains these general Java services:

• compareStrings -- Compare whether two strings are identical
• roundDecimal -- Round a number to two decimal places
• stringLength -- Returns the length of a string

In the remainder of the article, we will briefly describe the above services and provide their input/output signatures.
