# Jersey &version; User Guide

## Preface

This is user guide for Jersey &version;. We are trying to keep it up to date as we add new features. When reading the user guide, please consult also our Jersey API documentation as an additional source of information about Jersey features and API.

If you would like to contribute to the guide or have questions on things not covered in our docs, please contact us atusers@jersey.java.net. Similarly, in case you spot any errors in the Jersey documentation, please report them by filing a new issue in our Jersey JIRA Issue Tracker under `docs` component. Please make sure to specify the version of the Jersey User Guide where the error has been spotted by selecting the proper value for the `Affected Version` field.

### Text formatting conventions

First mention of any Jersey and JAX-RS API component in a section links to the API documentation of the referenced component. Any sub-sequent mentions of the component in the same chapter are rendered using a `monospaced` font.

Emphasised font is used to a call attention to a newly introduce concept, when it first occurs in the text.

In some of the code listings, certain lines are too long to be displayed on one line for the available page width. In such case, the lines that exceed the available page width are broken up into multiple lines using a `'\'` at the end of each line to indicate that a break has been introduced to fit the line in the page. For example:

    This is an overly long line that \
    might not fit the available page \
    width and had to be broken into \
    multiple lines.

    This line fits the page width.

Should read as:

    This is an overly long line that might not fit the available page width and had to be broken into multiple lines.

    This line fits the page width.
