Java and J2EE solutions

Java 2 Platform Enterprise Edition or J2EE for short is a platform for building and deploying web-based enterprise applications. It consists of a number of API's and protocols such as JSP/Servlets for the presentation layer, EJB for the logic layer and JDBC for the database connectivity layer. The application code runs within a Java Virtual Machine or JVM which is a black-box unless you have a tool which can look inside. Metrics about the JVM itself are easily available via JMX, but in order to properly diagnose the performance of the application you need a tool which can look in detail at the classes and methods that are being executed, without incurring too much overhead.

Performance diagnostics for Java and J2EE dynaTrace has several unique features which cannot be found in similar J2EE diagnostic products. At the core is the innovative is PurePath technology. PurePath technology enables deep root-cause analysis and allows transactions to be followed across servers. The PurePath contains not only the response time of the transaction and of the components involved but also contains context information along the path such as the method parameters, number of object calls, SQL database calls, log messages, exceptions and memory leaks.

Performance management for J2EE applications Symantec Indepth for J2EE is a comprehensive performance management solution for server-side Java applications. It is designed to run under load in production environments. As part of the i3 suite it is able to correlate J2EE activity with activity in other tiers such as web, database or ERP. The built in  SmarTune feature is able to instantly isolate the root cause of performance problems and recommend actionable advice. Adaptive Instrumentation can dynamically adjust the instrumentation level to a desired overhead budget without any application server restarts.
