Introduction

  • The required classes
  • An XML manifest file

In JDeveloper 10.1.3 the update center mechanism has been enhanced so that, by providing the location of an "Update Center XML file" containing all the required information on the web, anyone who wishes to write an extension can benefit from this facility. JDeveloper will then automatically upgrade the installed extensions when and where necessary.

Before explaining this further it should be noted that each extension is uniquely identified by an attribute called id that belongs to the root element of the extension manifest, called extension.
We will have to refer to this unique id when it will be about having your extension managed by the JDeveloper update center facility.

First you will need to create an update center. An update center is a specific XML document that can be reached through http. This XML document will associate an extension - using the unique id we talked about above - and a ZIP file containing:

  • the JAR file for the extension
  • another xml file named bundle.xml, in a META-INF directory

bundle.xml
