Quick Start (SOAP mode): Determining encryption type using the Java™ API

AEM Forms operations can be performed using the AEM Forms strongly typed API and the connection mode should be set to SOAP.

NOTE
Quick Starts in Programming with AEM forms are based on the Forms Server being deployed on JBoss® Application Server and the Microsoft® Windows operating system. However, if you are using another operating system, such as UNIX®, replace Windows-specific paths with paths that are supported by the applicable operating system. Likewise, if you are using another J2EE application server, ensure that you specify valid connection properties. See Setting connection properties.

Quick Start (SOAP mode): Encrypting a PDF document using the Java™ API

The following Java™ code example encrypts a PDF document named Loan.pdf with a password value of OpenPassword. The primary password is PermissionPassword. The secured PDF document is saved as a PDF file named EncryptLoan.pdf. (See Encrypting PDF Documents with a Password.)
