Web servers log many headers, therefore one has to be careful not to focus on just User-Agent. There are dozens of headers that are typically logged. We provide below a list of headers that we have already seen used in exploit attempts in the wild. The response to the JNDI request will be used to build the location of the object at:. At this point, Log4j will fetch and run payload2. Juniper Threat Labs has been seeing some amount of scanning looking for vulnerable servers.
A common method used by attackers is inserting the malicious request in the User-Agent header as most web servers will log this field to identify the browsers connecting to them.
But we have also seen attacks where the malicious requests are injected in different headers such as the ones below:. Apache has released Log4j version 2. It is recommended to immediately upgrade to this version. AntSpaces provides Ant integration with JavaSpaces. This allows you to coordinate Ant tasks via JavaSpaces, pull out work units from a JavaSpace for distributed Ant tasks to work on, and so forth. Timer is task for measuring the time elapsed to complete other tasks. A collection of powerful Ant extensions components organized into five categories: fixture-control, execution-rules, flow-control, feedback, and helpers.
With Build Number you are still in charge of the head of the version number. Build Number will take care of the tedium of managing the last two numbers interface and implementation. Checkstyle is a development tool to help programmers write Java code that adheres to a coding standard.
Its purpose is to automate the process of checking Java code, and to spare humans of this boring but important task. Note: As the Sourceforge project site shows, the last update was on Feb 16 Clover is an Ant-based Code Coverage tool. It can be used seamlessly with Ant-based projects. This task allows the generation of static web pages and sites using Apache Cocoon in off-line mode.
It allows the configuration information for Cocoon to be included within the Ant build file, and is thus able to take advantage of Ant properties. The task shares its code with the Cocoon Command Line, which means that this task will instantly take advantage of any new functionality added there. This project provides the following tasks: CreateEnumTask : Creates a Java enum based on commons configuration property files.
ExportPropertiesTask : Exports commons configuration properties to a external file in a using a specified format. LoadPropertiesTask : Loads commons configuration properties into pre-generated Java enum. A little CVS client that can be useful when people are behind corporate firewall that blocks any cvs communications.
Dependency Finder extracts dependencies and OO metrics from Java class files produced by most Java compilers. It can compute API differences between versions; no sources needed. It includes Ant tasks, web, Swing, and command-line interfaces, with XSL stylesheets for formatting output. You can use it to extract dependencies between packages, classes, or even methods, or any combination thereof. You can use Perl regular expressions to filter the information and pinpoint only what you need.
There is even a Web Application version WAR file so a whole group of developers can share a common view. It is a straightforward extension of the javadoc concept to the DTD file format. This way you can easily record performance metrics of your tests and get alerts to performance regressions.
EnvGen is an Ant task for generating different versions of the same file parameterized for different environments i. File generation is done using FreeMarker , a template engine with a full-featured templating language.
EMMA is an open-source toolkit for measuring and reporting Java code coverage. EMMA distinguishes itself from other tools by going after a unique feature combination: support large-scale enterprise software development while keeping individual developers work fast and iterative at the same time. EPP Task is an easy preprocessor ant task. The next directives are supported: ifdef, ifndef, else, endif and include. It is particularly designed for HTML preprocessor, for the generation of complete static homepages: directory structure that contains HTML-s, image files, etc.
But of course it can be used to generate source code or whatever text files. I still fix bugs and do other maintenance work check it here if I really do , so the project is not abandoned. Grand is a set of tools to create a visual representation of Ant target dependencies.
It works by taking an Ant build file and creating a "dot" file. It includes many advanced features such as filtering or rendering depending on the target's nature.
Greebo is an Ant-task for downloading dependency files currently only jars from a network to a specified directory, much like Maven. It supports multiple local and remote repositories with either flat or maven-like structures. It can read the dependency list from a Maven project file, a maven-like dependency file, or directly from the build. Note: As the Sourceforge project site shows, the last update was on Mar 12 You could also try Ivy.
It uses pre-execution class file recompilation, and generates XML files containing the coverage statistics. It does not require any advanced VM setup to generate coverage numbers.
Java code review tool. Performs automated code review. Contains inspectors which check different aspects of code quality including coding standards, EJB, threading, It parses the IDL file and determines the Java files that must be generated, taking in account the modifications that can happen due to command line parameters. If any of the Java files are missing or older than the source IDL specification, it launches the specified compiler.
To speed up the process and avoid unnecesary re-parsing, it keeps the dependencies in intermediate files. This task does not launch the javac compiler as well, that is, its output are Java files and not the final bytecode. ImTask is a task to allow one to send an Instant Message. Currently supports yahoo! Checks whether a given directory structure conforms to certain rules that are defined via nested elements of the task.
Ivy is a simple yet powerful dependency manager featuring continuous integration, dependencies of dependencies management, multiple repositories including ibiblio and high performance use of a local cache.
A small preprocessor allows to generate different variants of a MIDlet from a single source. Antic is a freely available task for packaging J2ME applications.
It produces both the Jar and Jad files in a single step. It covers the whole circle of preprocessing, compiling, obfuscation, preverifying, packaging and JAD-creation. J2ME Polish is ideal for creating device optimized applications with its powerful preprocessing capabilities and the integrated device database.
With J2ME Polish no hardcoded values are needed and the portability of an application is not sacrificed, even though highly optimized applications are created from a single source.
Jacson is a configurable and plugable tool much like Ant itself to create filters for text line based files without programming. It is fully configurable and can be used to generate Mac OS X application bundles from any supported Java platform, making it ideal for targeting multiple platforms with one build.
JarPatch is a task that generates a zip file resulting of the diff between the content of 2 jar files. The resulting diff file can be use as a patch for a previous installation just ensure that the generated patch.
There are two different tools both named Java2HTML that process Java source code and generate syntax highlighted documentation from it. Both include Ant tasks to run them. Java2Html library for converting java source files or snipplets to syntax highlighted html, rtf, tex and others. A task to compile Java sources and manage class file dependencies. Functionality is equivalent to that of standard Javac and Depend tasks combined, with improved dependency checking.
It is a command line tool with an Ant task to scan whole package trees. The result can viewed in an JavaDoc style web page. JDeb provides an Ant task and a Maven plugin to create Debian packages from Java builds in a truly cross platform manner. Build your Debian packages on any platform that has Java support.
Windows, Linux - it does not require additional native tools installed. A task that generates an HTML report of all the packages, classes, constructors, methods, and fields which have been removed, added or changed in any way, including their documentation, when two APIs are compared. JFlex is a lexical analyzer generator also known as scanner generator for Java, written in Java.
JindentTask is a very straightforward wrapping of the Jindent tool, a vendor code beautifier. It enables to use Jindent natively from Ant. It provides tasks for getting and setting attributes of MBeans, invoking their methods and much more. Note: As the Sourceforge project site shows, the last update was on May 28 It includes a code generator that generates both Java "proxy" classes to access C "peer" classes, and C "proxy" classes to access Java "peer" classes or interfaces.
It also includes a core library with a simplified JVM interface as well as "helper" classes to ease working with the JNI data types. Ant is extremely flexible and does not impose coding conventions or directory layouts to the Java projects which adopt it as a build tool. Software development projects looking for a solution combining build tool and dependency management can use Ant in combination with Apache Ivy.
Apache Ant 1. The Apache Ant team currently maintains two lines of development. The 1. Both lines are based off of Ant 1. We recommend using 1. Here are the different ways to do this. When you run Ant on Java 5 or above, you could try to use the automatic proxy setup mechanism with -autoproxy. This is the best option for a non-mobile system. For a laptop, you have to change these settings as you roam. For Windows, set the environment variable in the appropriate dialog box and open a new console or, by hand.
If you are writing a build file that is always to be used behind the firewall, the setproxy task lets you configure the proxy which it does by setting the JVM properties.
If you do this, we strongly recommend using Ant properties to define the proxy host, port, etc, so that individuals can override the defaults. The Ant team acknowledges that this is unsatisfactory. Setting properties on Ant's command line do not work, because those are Ant properties being set, not JVM options.
This means the following does not set up the command line:. One other trouble spot with proxies is with authenticating proxies. Ant cannot go beyond what the JVM does here, and as it is very hard to remotely diagnose, test and fix proxy-related problems, users who work behind a secure proxy will have to spend much time configuring the JVM properties until they are happy.
Note : Since Ant 1. The easiest, and best way is to get these external libraries from JPackage if JPackage has them available. Note: for each such library, you will have to get both the external package itself e. However, JPackage does not package proprietary software, and since some of the optional packages depend on proprietary JARs, they must be handled as follows.
This may violate the spirit of JPackage, but it is necessary if you need these proprietary packages. For example, suppose you want to install support for NetRexx, which JPackage does not support:. To build Ant from source, you can either install the Ant source distribution or clone the Ant repository from Git. See Source Distribution for details.
See Installing Ant for examples on how to do this for your operating system. It does not work with gcj or kjc. Make sure you have downloaded any auxiliary JARs required to build tasks you are interested in. Note that this will make the auxiliary JAR available for the building of Ant only.
You can also get most of the auxiliary JAR files i. See Optional Tasks for instructions on how to do this. The fetch. On most occasions you will not need to explicitly bootstrap Ant since the build scripts do that for you. However, if the build file you are using makes use of features not yet compiled into the bootstrapped Ant, you will need to manually bootstrap. Run bootstrap.
Ant's build script will try to set executable flags for its shell scripts on Unix -like systems. There are various reasons why the chmod task might fail like when you are running the build script as a different user than the one who installed Ant initially. In this case you can set the Ant property chmod. The following libraries are needed in Ant's classpath if you are using the indicated feature.
Note that only one of the regexp libraries is needed for use with the mappers and Java includes a regexp implementation which Ant will find automatically.
You will also need to install the particular Ant optional JAR containing the task definitions to make these tasks available. Ant has a built in diagnostics feature.
