ePay Application development:
To develop ePay application based on java/J2ee, XSL parsing ,MQ via EJB.
Data extraction from database through EJB 2 and IBM MQ.
To design XSL by using these data (pay attributes).
Represent the XSL into HTML and PDF.
Developed the modules in Struts1.3 MVC pattern and used Spring Hibernate integration to access/modify the data present in the database.
Used XSD for validating classes through Jaxb.
ETL Tool development:
To develop a tool named as the ETL, which will be used to extract the data from the result returned on executing the query given by the user. A configuration file will have all the database connectivity information which can be updated by the user based on their need. This makes the tool to be more flexible and customizable to connect to any supported databases. This is a desktop application which will be developed using Java Swing. As per client standard, this application uses AES 256 encryption algorithm to encrypt the data file. Along with that, a Decryption Tool was also developed to decrypt the encrypted data files using the same algorithm. RSA public/private key pair was generated in order to encrypt the AES private key and the same RSA public key is used to decrypt the AES key.
Apart from that, Windows Scheduler functionality is incorporated by using the SCHTASKS command from within the application.
Description: Involved in the development of 2 tools:
a) Generic Data ETL Tool
Main functionality of this tool is:
Data Extraction from Database and transformation to CSV format.
File Encryption using AES 256 algorithm
File Transmission via SFTP (using Apache commons API) and file purging.
b) Decryption Tool
Main functionality of this tool is:
Data File download (using Apache commons API) and deleting the already downloaded files from SFTP after successful download operation.
Decryption of downloaded files using AES 256 bit algorithm
Uploading the decrypted files to FTP (using Apache commons API).
