Application server performance. Database performance. Hardware performance.
These are numbers measured in the popular press, although in most situations
they have little to do with your application's real-world performance. The
number one way to increase performance, the thing that gives you the biggest
boost, is caching. Caching in every tier is becoming more and more prevalent.
On the front end, we have caching proxy servers like Squid and AOL. On the
back end, we have databases and file systems that are caching our data. This
month, I'm going to talk about caching in the Web application layer of the
middle tier, where your application meets the Internet.
In WebLogic Server 5.1, the JSP cache tag was introduced for caching in the
Web application tier. This tag allows y... (more)
Working at a software company and watching products evolve over the years,
"Migrate Early, and Often"is the best advice I can give someone who is trying
to stay on the cutting edge of technology. Obviously, if you have an
application that's in production with no problems and you aren't planning on
adding any new features, then of course keep the same version of the
underlying platform. H... (more)
The Java Management API (JMX) has been integral to managing the WebLogic
Server since WebLogic 6.0. Through this API you can search for management
beans (mbeans) within the application server and query them for both
configuration information and runtime monitoring information. In addition,
this API can be used to actually change the configuration of the server. In
fact, this API is used ... (more)
EJBs have always been the best way to ensure that your applications were
portable and would leverage all the optimizations of the J2EE server. Now
they are also easy to build. With the release of WebLogic Platform 7.0, you
can create EJBs in record time. At the center of this revolution is Container
Managed Persistence 2.0, which allows WebLogic to build tools that remove the
layers from... (more)
WebLogic Server 7.0 contains the most advanced, performant, and
standards-compliant Web service stack of any application server. With an
additional download (until the JAX-RPC specification goes final - it may by
the time you see this article - see http://jcp.org/jsr/detail/101.jsp) you
get a Java standards-compliant Web service stack that also passes the SOAP
interoperability tests. So ... (more)
Sam Pullara has been a software engineer at WebLogic since 1996 and has contributed to the architecture, design, and implementation of many aspects of the application server.
