Recently in Adobe LiveCycle Digital Signatures ES Category

Although LiveCycle ES is supported on a wide variety of enterprise platforms, there are combinations of J2EE appserver-DB-OS that might not be supported. For example, JBoss on AIX is not supported. WebSphere with MySQL is not supported. Sybase is not supported at all.

To ensure that you install LiveCycle on a supported platform, please consult the most appropriate "Preparing to Install" guide or use the Software Environment and Compatibility Check (SECC) form. The SECC form asks all the relevant questions when it comes to an installation of LiveCycle in a particular environment. It is recommended because you have the option to have it reviewed by Adobe.

Adobe Reader 9 offers a great new perspective on Digital Signatures and how they are viewed by end-users. You will notice that the validity of the signature is no longer indicated by an icon directly on the signature itself (the famous yellow triangle). Instead, you will find a new bar provided at the top of the PDF indicating the validity and status of the signatures on the form. For additional detail on individual signatures a new side-bar gives you a full view of individual signature status along with form changes that may have occured between signatures (for example).

If you would like to ensure that users do not apply Digital Signatures to incomplete forms, after the signature is applied, reset the Signature field using the "resetForm" method along with the full name of the signature field:

var doc = event.target;
doc.resetForm("XMLExampleForm[0].XMLExamplePage1[0].SignatureField1[0]");

In this example the user must enter the Name field to apply a valid signature. If the Name is removed or the Name is not entered, the signature field is cleared.

If you would like to enable Digital Signatures on a PDF that is going to be passed to different users through a LiveCycle ES Process, here are a few short guidelines for you.

On the form itself:

In the process design:

If you would like a sample of a PDF Form and a Process including a Digital Signature, feel free to download this LCA (LiveCycle Archive for Adobe LiveCycle ES) https://share.adobe.com/adc/document.do?docid=b71a87c5-f6a8-11dc-8d05-e593509263b8

If you would like to display the properties of a Digital Signature on your form, or have your form react to the change of a signature, here is a quick sample that should give you a head-start. The second signature on the form will not appear until the first signature field is signed.
