Apache Commons Validator provides the building blocks for both client side validation and server side data validation.
It may be used standalone or with a framework like Struts.
Documentation

More information can be found on the [Apache Commons Validator homepage](https://commons.apache.org/proper/commons-validator).
The [Javadoc](https://commons.apache.org/proper/commons-validator/apidocs) can be browsed.
Questions related to the usage of Apache Commons Validator should be posted to the [user mailing list](https://commons.apache.org/mail-lists.html).
Getting the latest release
--------------------------
You can download source and binaries from our [download page](https://commons.apache.org/proper/commons-validator/download_validator.cgi).
Alternatively, you can pull it from the central Maven repositories:

Building
--------
Building requires a Java JDK and [Apache Maven](https://maven.apache.org/).
The required Java version is found in the `pom.xml` as the `maven.compiler.source` property.
From a command shell, run `mvn` without arguments to invoke the default Maven goal to run all tests and checks.
Contributing

We accept Pull Requests via GitHub. The [developer mailing list](https://commons.apache.org/mail-lists.html) is the main channel of communication for contributors.
There are some guidelines which will make applying PRs easier for us:
+ No tabs! Please use spaces for indentation.
+ Respect the existing code style for each file.
+ Create minimal diffs - disable on save actions like reformat source code or organize imports. If you feel the source code should be reformatted create a separate PR for this change.
+ Provide JUnit tests for your changes and make sure your changes don't break any existing tests by running ```mvn```.
