JProfiler's intuitive GUI helps you find performance bottlenecks, pin down memory leaks and resolve threading issues. If you have Java code and wish to OptimizeIt then Jprofiler is an essential tool.
- JProfiler works both as a stand-alone application and as a plug-in for the Eclipse software development environment.; JProfiler supports local profiling (analysis of applications running on the same machine as the JProfiler software) and remote profiling (analysis of Java applications running on remote machines).

Application Server Tutorials
- The following tutorials are for enterprise developers interested in container or application managed persistence using the JPA 1.0 or 2.0 API.
- See the Distributed JPA Application case study on how a Service/Workers parallel pattern based application uses JPA to deal with Optimistic lock exception scenarios using Java EE 6 API elements - specifically as a single persistence unit used by the distributed application as an alternative to using a shared L2 cache.
Enterprise Application Servers
- Step by step instructions by container for a quick-start Java EE EclipseLink JPA container-managed Application using a single JPA Entity on the major subset of all application servers
- We use a standard container managed @PersistenceContext(.TransactionType dependency injected EntityManager) that is injected on a @Stateless session bean so that the container can provide a thread safe proxy wrapper around the @NotThreadSafe EntityManager and provide us with instrumented transaction management and change tracking. The client servlet gets injected with the @EJB SSB by the web container and is completely separated from the JPA persistence concern.
- These tutorials need to be finished and/or expanded - vote for EclipseLink bug# 308477 if you would like this work to be fast tracked.

EJ Technologies JProfiler 11.0.1 Build 11070
JProfiler is a powerful tool that you can use to profile Java based applications in a dynamic way and enables you to analyze them in hopes of optimizing performance.
EXCEPTIONAL EASE OF USE
When you profile, you need the most powerful tool you can get. At the same time, you do not want to spend time learning how to use the tool. JProfiler is just that: simple and powerful at the same time. Configuring sessions is straight-forward, third party integrations make getting started a breeze and profiling data is presented in a natural way. On all levels, JProfiler has been carefully designed to help you get started with solving your problems.
DATABASE PROFILING FOR JDBC, JPA AND NOSQL
Database calls are the top reasons for performance problems in business applications. JProfiler's JDBC and JPA/Hibernate probes as well as the NoSQL probes for MongoDB, Cassandra and HBase show the reasons for slow database access and how slow statements are called by your code. From the JDBC timeline view that shows you all JDBC connections with their activities, through the hot spots view that shows you slow statements to various telemetry views and a list of single events, the database probes are an essential tool for getting insight into your database layer.
EXCELLENT SUPPORT FOR JAVA ENTERPRISE EDITION
Jprofiler 10 1 1 – Java Based Applications Examples
Dedicated support for JEE is present in most views in JProfiler. For example, in the JEE aggregation level you see the call tree in terms of the JEE components in your application. In addition, the call tree is split up for each request URI. Also, JProfiler adds a semantic layer on top of the low-level profiling data, like JDBC, JPA/Hibernate, JMS and JNDI calls that are presented in the CPU profiling views. With its JEE support, JProfiler bridges the gap between a code profiler and a high-level JEE monitoring tool.HIGHER LEVEL PROFILING DATA
JProfiler has a number of probes that show you higher level data from interesting subsystems in the JRE. In addition to the Java EE subsystems like JDBC, JPA/Hibernate, JSP/Servlets, JMS, web services and JNDI, JProfiler also presents high level information about RMI calls, files, sockets and processes. Each of these probes has its own set of useful views that gives you general insight, highlights performance problems and allows you to trace single events. And what's more, all these views are also available for your own custom probes that you can configure on the fly within JProfiler.
