| Abstract | The practice of enhancing the bytecode of Plain Old Java Objects (POJOs) with additional capabilities, including persistence, distribution, and security, has become an indispensable part of enterprise software development. The resulting transparently-applied, large-scale structural changes to the bytecode significantly complicate symbolic debugging. This demonstration will showcase the Anti-Goldilocks Java (AGJ) debugger, which enables the programmer to trace and debug transparently transformed programs, without the distraction of the bytecode-level enhancements obfuscating the program's source code. AGJ executes a structurally enhanced program, while dynamically reinterpreting the debugging output (e.g., 'step', 'print variable', etc.) to display program information as pertaining to the original version of the code. AGJ is based on a new debugging architecture that leverages our domain-specific language for describing enhancements. A paper in the main technical program of OOPSLA 2009 [5] describes the design rationale and implementation details of AGJ. This demonstration will showcase the functionality of our reference implementation by using it to locate bugs in a framework-based enterprise application from the financial industry. Using the domain of transparent persistence, this demonstration will compare AGJ to the standard JDK debugger, thereby highlighting the capabilities of AGJ to cut through the morass of transparent bytecode enhancements in order to find obscure bugs. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
