Adding a Document to a Case Using FileNet CE Java API

In this sample code, a ByteArray stream, document name, document class, and CaseFolder ID are passed as method parameters. To attach a document to a case, it must be added to the case folder. Once added, it will appear as an attached document when the case is opened.

Prerequisites

• Ensure that the required FileNet libraries, such as cejava.jar and pe.jar, are included in your project’s classpath.
• Have the Content Engine’s endpoint URL, username, and password ready.

Testing

• Run the program in a Java environment to establish a connection to the Content Engine and create document.
• Check the case folder to verify whether the PDF document has been created or not.
