Implementation work on a web application for an application system for the acquisition of raw material data. This is realized in JSF 2.x in connection with the RichFaces component library and the Spring Framework. The focus is on the processing and display of documents (such as contracts and information documents) that are implemented in the area of signing PDF documents and master data displays.
Supplement
In detail, the implementation of the signing of PDF documents is an extension of the SUIS PDF Signer (RFC 3161-compatible in the form of Suis Security Tools 2.1.20 and Suis Batchsigner 1.6.3) using signature hash SHA 256+, Java-based PKCS12 with JKS, IText 2.1.7 (still open source!) and Bouncy Castle (in the form of bctsp-jdk15-1.45 and bcprov-jdk15-1.45) based on preliminary work from another project and the implementation of master data displays on sales representatives in the form of contacts display for growers.
