Need to make JNI calls (linking to C libraries) via Forms customization. (on EBus 11.5.10.2)

 We are on Ebus 11.5.10.2 and eventually 12. We are asked to hook up to an encryption tool to encrypt/decrypt personal information. This would be via Forms customization. The encryption tool will require a JNI interface which calls native C libraries. Is there a way to invoke that interface via something like the old Forms 6i ORA_JAVA or a Java importer tool? Is there a more current capability to perform this function via Forms customization? Thanks
