JCola is a file tailing application written in Java Swing. This multithreaded application can tail an unlimited amount of logfiles concurrently and simulates "tail -f" with much more functionality.

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.

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

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

This project was intended to implement the Java(tm) Platform Debugger Architecture for JOS. It is currently inactive.

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.

Jssltrace is a java-based tool, which enables it's user to intercept ssl based communication between two programs. Jssltrace works essentiallly in the same manner as tcptrace (http://www.pocketsoap.com/tcptrace), which is the main inspiration for it.

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JSwat project has moved to Google Code: http://code.google.com/p/jswat/ -- the contents of the SourceForge project are no longer being updated.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.

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.

JTestCase uses XML file to organize multi-testcase data and asserting conditions (action and expected result), and provides a set of easy-to-use methods to retrieve test cases out from XML, and asserts results against those expected ones in data 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.

Jassda is a framework that extracts a sequence of method-invokations from a Java application during runtime using the Java Debug Interface (JDI). Jassda provides two modules that operate on the sequence: a logger and a trace-checker

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)
