JavaDocs Generator Tools

Since this week starts, I've been searching a tool to generate JavaDocs on JIRA confluence Wiki Markup format. There are a lot of tools that generate JavaDocs in HTML, RTF and PDF formats, but for the moment I haven't found any tool that can make that for me. Though, there is a tool called Doxygen which generates documentation system for C++, C, Java, Objective-C, Python, IDL and to some extent PHP, C#, and D. In addition to JavaDocs generated, this tool can generate Inheritance diagram and Collaboration diagram of all the classes that you have in the projects. You can also integrate this tool with Maven framework.
