JProfiler is a debugging tool for Java programs. It helps you resolve performance bottlenecks, pin down memory leaks, and understand threading issues. 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.
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.
