Resolving Interoperability Issues of Precision and Array with Null Value of Web Services Using WSIG-JADE Framework

Abstract

Web services and agent technology play a significant role while resolving the issues related to platform interoperability. Web service interoperability organization (WS-I) provided the guidelines to remove the interoperability issues using basic profile 1.1/1.2 product. However, issues are still arising while transferring the precision values and an array with null values between different platforms like JAVA and .NET. As in a precision issue, JAVA supports data precision up to the 6th value and .NET up to the 5th value after the decimal and after increasing their limits, the whole number gets rounded off. In array with a null value issue, JAVA treats null as a value but .NET treats null as an empty string. To remove these issues, we use the WSIG-JADE framework that helps to build and demonstrate a multiagent system that does the mapping and conversions between agents and web services. It limits the number of digits to the 5th place after the decimal thereby increasing the precision in data sets, whereas it treats null as an empty string so that string length remains the same for both the platforms thereby helping in the correct count of data elements.

Design of intelligent agent on Moodle to automate the learning assessment process

“…We were able to detail our MARA platform, however the integration side with the Moodle platform remains less explicit. For this reason, we used the WS2JADE technology [26] which aims at a symmetric integration of FIPA-compliant agents and web services as detailed in [27]. The latter, which uses a strategy based on proxies, allows the two platforms to develop independently of each other.…”
