Java - manage object oriented software development language

I first looked at Java in 1997. I thought that it looked pretty good, but needed a few years to mature. I currently think that it is getting close. Java has many of the same constructs as C++ for building applications, lacks some of the most powerful and adds some very useful object / class management tools.

Here are some of the solutions that I have done in Java:

• The company wanted to develop Java applications, but was worried about the performance of Java on certain process intensive sections of the system. I designed an n-tier applicatiion framework with duplicate APIs in C++ and Java, This allowed business logic developed in Java to be moved to C++ by passing it through a perl program that could strip the "new(s)" needed for the Java object declarations. The C++ objects were reference counted, so that they were functional equivalents of their garbage collected Java counterparts. Application level C++ code contained no memory management code and no pointers.
  • Framework used a factory product pattern to persist and transmit objects between the tiers and database.
  • Factory classes cached objects to reduce relocating objects from other tiers.
  • Attributes of objects were tracked for modification, allowing updates between tiers to be reduced to just changed data.
  • Database column names were detached from member names of classes. This allowed member data to have names far larger than the 10 character column name limit in DB2
• The comapny was interested in the performance of Java in processing Database operations, I wrote a set of benchmarks that tested different ways of accessing and updating data in tables. These tests were run against Oracle and DB2. I also made a duplicate program in C++ as a reference.
• I have several JSP web sites, I use Java to build Beans that the JSP pages can use to interface with system and database resources.
