Utilities for diagnosing problems with JDBC connections

Allows JDBC resources to be monitored. You can see when java.sql objects are being opened and closed and can see the line of code where a resource that is still open was originally opened.

JDBC-XML Driver for Mysql 4.0. Allow efficient definition ,storage and retrieval of answers to forms. This JDBC-XML driver is an extension to the mysql JDBC Driver adding XML capabilities.

JDLabAgent is a dynamic link library which is loaded into the Java Virtual Machine via Java Virtual Machine Debug Interface (JVMDI). The JDLabAgent can be parameterized via config files and logs JVM events (e.g. breakpoints, exceptions).

JDLabStudio is a graphical front-end for the Java Debugging Lab Agent (JDLabAgent). JDLabStudio scans java packages, displays class files and generates JDLabAgent config files. JDLabAgent-traces are used for reconstructing control and data flows.

JDumpViewer is a graphical tool used to analyze Java thread dumps

An Open Source Java Emulation platform for emulating micro computers

Simple - but complete enough - command-line Bash debugger, written as a Bash script. No installation and no root permission required: just download, put every where you prefer and use it. Bash 3 required.

JHeap provides the toolset to help Java developers discover and fix the root cause of memory issues in their applications. JHeap integrates easily with your application server and has been designed to be used in production environments with low overhead.

JLinkCheck is an Ant Task written in Java for checking links in websites. It is not just checking one single page, but crawling a whole site like a spider, generating a report in XML and (X)HTML. JReptator will be its succesor with many more features

JPeek is a graphical tool and library for reflection-based runtime inspection of the object graph in Java.

A viewer to view and analyze the old Java profiler's (java -prof MyApp) output. With the help of this software it is easier to choose the methods to optimize, so you need not optimize all your methods.

JRemoteRun allow execute snippets of java code in running JVM.

Java AS400 RPG source code editor, debugger, IDE.

The JSwat project has moved to Google Code: http://code.google.com/p/jswat/ -- the contents of the SourceForge project are no longer being updated. Please visit the new site. Thank you.

The "JTAG-GDB server" is a program for integrating the ARM-Embedded ICE logic with the GNU-Debugger GDB.

JTail is a simply multiplatform application, which show text files content especially LOG FILES. This application is a thread, which non-stop reads the file content and print what lines was added to the end file.

A facility to keep a history of context information during runtime and then dumping it in a separate file when a problem occurs (similar to core dump).

Aligns java-files, which are decompiled by jad

Hugo is a small Android library (and annotation processor plugin) that automatically logs method calls, parameters, return values, and execution time for methods annotated with @DebugLog. Instead of manually adding logging statements everywhere, you simply annotate a method and Hugo injects the logging at compile-time in debug builds, keeping release builds clean. This helps developers gain visibility into method flows, execution timing, and parameter passing without cluttering production code. The annotation doesn’t remain in the compiled class for non-debug builds, so there’s zero runtime penalty in release. Hugo uses bytecode/annotation processing behind the scenes but maintains simple API usage for developers. It’s especially useful during development and debugging phases in large Android codebases where tracing logic by hand would be tedious.

JBCD is an interactive debugger for Java bytecode. It allows a programmer to step through bytecode one statement at time. The tool is indended for people who are writing programs to generate or modify bytecode. JBCD can be used with any Java compiler a

Java-program to read, modify and execute class-files. a real java VM written in java or a decompiler for class-files is possible (and partially working)

Utilises the JVMDI (Java Debug API) to produce line coverage reports detailing which lines of code have been executed during a test. Report is produced in XML and may be post-processed via XSLT into a prettier one.

This is going to be a Java Swing Application that will be used as a quick reference for Java API names. It will feature incremental search and filtering so that searching efficiency is improved. It will be very simple and a good way to statistically analyze java api's.
