1. commons-beanutils:

The easy-to-use wrapper in the Java reflection and introspection API provides low-level utility classes that help get and set property values in Java classes that follow the naming design pattern outlined in the JavaBeans specification and the mechanism for dynamically defining and accessing bean properties

• Commons-beanutils-core.jar
• Commons-beanutils-bean-collections.jar

2. Commons-dbutils:

There is no possibility of resource leaks. The correct JDBC coding is not difficult, but it is time-consuming and tedious. This usually leads to a connection leak, which can be difficult to track
Cleaner, clearer persistence code. The amount of code required to save data in the database is drastically reduced. The rest of the code clearly expresses your intentions without being flooded with resource cleanup.
The JavaBean property is automatically populated from ResultSets. You do not need to manually copy the column values into the bean instance by calling the setter method. Each line of the resultset can be represented by a fully populated bean instance

3. commons-FileUpload:

If an HTTP request is submitted using the Post method and has a content type with "multipart/form data", then FileUpload can parse the request and provide the result in a way that the caller is easy to use

4. commons-io:

Commons io is a library of utilities to help develop IO features

5. commons-Lang:

Lang provides a number of assistive tools for Java. Lang APIs, especially string manipulation methods, basic numeric methods, object reflection, concurrency, creation and serialization, and System Properties
In addition, it also contains a pair of java. The basic enhancement of util. Date and a series of utilities used to help build methods, such as Hashcode, ToString, and equals

6. commons-Logging:

libraries that use the common-logging API can use any log implementation at run time. Common logging supports many popular log implementations, and writing adapters for others is a fairly simple task
-Logging does allow the application to change to a different logging implementation without recompiling the code
