![]() ![]() Without this config change you will need to use and do some manual processing, this is (encoding) error prone. This will allow you to use HttpServletRequest.getPart() and HttpServletRequest.getParts() to get multipart/form-data parts. Here is an example:Ĭom.zimbra.cs.extension.ExtensionDispatcherServlet Jar files are in fact zip files containing compiled Java classes in a specific folder structure and a Manifest file. Zimbra extensions are deployed using jar files. Existing REST/SOAP Zimbra API documentation can be found at: This article will focus on REST extensions because of the support for JSON and file up- and downloads. If you are writing a simple extension that only needs to parse a few options, using REST can seem more straight forward as it is a little easier to test and debug not having to create XML payloads for the requests and parse the XML response but it is a matter of personal preference. In recent years developers of commercial and social web applications seem to favor REST over SOAP, but in government and healthcare applications SOAP is still common. A REST extension can be made to authenticate the user, but it is also possible to interact with non-authenticated users. As such you may find it easier to find documentation and examples on the Internet. REST extensions on the other hand are based on, a third party class that is used frequently in other Java projects. Which means you do not have to worry about authenticating the users of your SOAP extension. One benefit of SOAP over REST in Zimbra extensions is that the authentication of the user is enforced by Zimbra in SOAP extensions. You can use GET parameters, POST HTML forms, POST XML or JSON data and upload/download (binary) files. With REST you have the freedom to define your request and response content. When using SOAP you must always use XML to make the request to the server and the server will respond in XML as well. REST and SOAP can do a lot of the same things but in a different way. Extensions marked with (*) are not commonly implemented, they may require some research and updating to work. Some additional information can be found in the /opt/zimbra/docs folder on your Zimbra mailbox node. This one does not technically implement a Zimbra server extension, but may be useful if one wants to implement SAML. ![]() You can use this to change the password on a non-Zimbra auth back-end like Active Directory.Įxtends .Īllows to create additional storage back-ends for Zimbra. This extension can be called whenever the user changes the account password. Supports authenticating Zimbra users using a 3rd party auth back-end. Implements a SOAP API, can only be accessed by authenticated users and can be tied to the regular front-end or the admin console. Implements .extension.ExtensionHttpHandler / Implements a REST API, if you need authentication you must manually implement it, supports file uploads. Change Password on custom authentication.Zimbra supports extensions for the following functionality: To get started quickly it is recommended to use Ubuntu 20 and our automated installer: Zimbra extensions Your test server needs to be accessible over SSH. If you decide to set it up on your local computer you need at least an i5 with 16GB of RAM and a SSD. You can set this up in a Virtual Machine in the cloud or you can install it on your local computer inside VirtualBox/KVM/Parallels etc. To follow the steps in this article you need a Zimbra test server. A good online course can be found at Prerequisites Having good fundamentals will improve your coding and productivity. Following such a course will help you understand the Java language fundamentals. ![]() If you have never wrote software before or find the Java code in this article overwhelming, you may find it helpful to follow a Java course first. This article is a practical guide to writing Zimbra back-end extensions. The Zimbra front-end can be extended with JavaScript Zimlets and the back-end can be extended with Java extensions. ![]() One of the powers of Zimbra is the ability to be extended with custom functionality. ![]()
