1) When dealing with digital signatures, how come you have not looked into onboard tools?

You can use digital signatures and document encryption in your application to provide document security: Secure Store and Forward Mechanism (SSF)

You will need the SAPCRYPTOLIB installed on your application server, depending on your SAP ABAP version, it might be already installed.

ABAP Function Modules of the SSFG Function Group:

• SSF_SIGN / SSF_KRN_SIGN Creating digital signatures
• SSF_VERIFY / SSF_KRN_VERIFY Checking digital signatures
• SSF_ENVELOPE / SSF_KRN_ENVELOPE Encrypting documents
• SSF_DEVELOPE / SSF_KRN_DEVELOPE Decrypting documents

2) Using SAP Jco to connect ABAP with Java

If you want to call custom Java Code from ABAP, you will have to make use of the SAP Java-Connector (SAP JCo).

• You can either call a Non-SAP Java-Application that implements the JCO and call it by RFC
• Or you can call a SAP Java Application through Jco/JRA calling it by RFC

SAP Jco/JRA for SAP Java Applications

• If you want to stay with a SAP product and call custom Java Code from ABAP, you will have to look into "SAP NetWeaver Application Server for Java (AS Java)" and use "SAP Java Resource Adapter (SAP JRA)" with remote SAP Java EE application servers. SAP JRA is an add-on to the SAP Java-Connector (SAP JCo): SAP JRA Server Programming Model
• Developing can be done, for example, in "SAP NetWeaver Developer Studio" or Eclipse.
