Java Blend: Integrating Java applications with Enterprise data
=========================================
by Tim Learmont
This talk describes a new technology for database
application programming in Java that provides transparent
integration of Java classes with databases. Enterprise
developers can write 100% Pure Java programs to retrieve and
modify data from a database as Java objects; the mapping
between the data (such as rows in a relational database) and
the Java classes is handled automatically. This greatly
increases programming productivity by eliminating the need to
write SQL or understand the details of corporate database
schemas. Retrieving data is accomplished using Java classes
and collections; modifying persistent data is as simple as
modifying any other Java data, with the additional benefit of
transactions ensuring consistency between multiple users.
Business logic is coded in Java as part of the class,
improving reuse and maintainability.
=========================================
JavaCC: Building Parsers Using the JavaCC ToolSet
=========================================
by SriRam Shankar
In this talk I'll present an overview of the JavaCC toolset - the Java
parser generator, the scanner generator, and the tree builder from Sun
Microsystems. It was released for the first time in October 1996, and
currently has thousands of users all over the world using it on over
40 different platforms. I'll highlight its unique features and plans
for future work, and talk about the various pros and cons of using
JavaCC in your applications. I'd like this talk to be interactive -
please come with questions and issues to talk about.

Biography: Tim Learmont
=====================
Tim Learmont works at Sun Microsystems, in the Java Enterprise
Technologies group. In the early days of Sun, Tim was one of the
original members of the database group at Sun, trying to make it easier
for programmers to access databases. After many other projects (and a
stint writing video games), Tim finds himself back in a database group,
still trying to make it easier for real programmers to get information
from databases. It is his fervent hope that Java Blend will solve this
problem (at least for Java programmers), allowing him to turn his
attentions to other things.
=====================
Biography: SriRam Shankar
=====================
SriRam is an alumnus of Stanford University's computer science
department. Previously, he was at Indian Institute of Technology,
Kanpur. His research interests are generally in the area of software
engineering and language design. At Stanford University, his PhD
thesis was on developing translation schemes for specification
language constructs - hence enabling the use of formal specifications
in the testing process. He moved to Sun from Stanford and joined a
research group called PrimaVera, where we further refined these
strategies for specification based testing and took it closer to the
software engineer through our work on ADL. He was the manager and
principal investigator of this group for two years.
Recently, his group had been reorganized as part of Sun Laboratories' policy
of moving research ideas to products
through moving the people themselves. He was a part of a business unit called
SunTest focusing on building high quality
software testing products for both developers and testers.
He managed the Java Compiler Compiler (JavaCC, previously Jack)
project and the JavaScope project.
SriRam has a passion for anything to do with compilers, software development
environments, language design, etc. He built a
large part of an Ada compiler for his senior year project between 1981 and
1983. His PhD thesis, and his work at Sun
have had a lot to do with compiler front-end issues. Around 1991, he got fed
up of the limitations of LALR(1) grammars
and did some research on algorithms for parsing general context-free
grammars (including ambiguous grammars). The final
result of this work was a tool that generated not only parsers, but also
syntax directed editors for any context free
grammars (with no restrictions). He built a couple of parsers/syntax
directed editors with this tool. I got introduced to
PCCTS at this time and was convinced that the absence of left recursion was
not that big a deal.
So in 1996, he started building a parser generator for Java. Soon Sreeni and
Rob joined me in this project and they were
able to build a good enough tool that they could release for everyone to use.
This tool is Java Compiler Compiler, which
currently has a serious user base of over 1000 people and has been
downloaded over 15000 times.
During the early stages of the JavaCC project, Juei tried using JavaCC to
build a coverage tool. He built a quick
prototype within a week and convinced us to start a project to productize
this coverage tool. This became JavaScope
which went on sale for the first time on April 2, 1997.
More exciting interests of his are his extra-curricular activities such as
sailplane gliding, gardening, home projects,
running, etc.
SriRam recently left Sun to start his own company, Metamata Inc.
