WebLogic History
WebLogic, Inc., was founded by Paul Ambrose, Bob Pasker, Laurie Pitman, and Carl
Resnikoff, in September, 1995.
Up until then, Paul and Carl had been developing (pre-JDBC) Oracle, Sybase, and
Microsoft SQL Server database drivers for Java under the name dbKona, as well as
a "three tier" server to permit applets to connect to these databases. An old
dbKona/An T3 Usenet posting. This was the WebLogic 1.48 server, and was called
T3Server (a bastardization of 3-Tier Server).
Concurrently, Laurie and Bob had been working on network management tools in
Java. Bob had written a SNMP stack in Java and a W32 native method for ICMP
ping, while Laurie worked on applets to display the management data.
One of the hidden features of the 1.48 server version was the ability to extend
it by modifying a dispatcher and adding a handler for different types of
messages. Bob talked Paul into sending him the source code for the server, and
Bob extended it so that Applets could make SNMP and PING requests on the
network, and display the results.
At this point, the founders worked together to pursue what was eventually to be
called the Application Server.
