[xwiki-users] Swizzle Plugin Questions

Hello, I am working on a xwiki site that wraps the jira functionality. I want to be able to work from the site on xwiki as if I were on the jira site. I am using the Swizzle Plugin to create the xwiki interface to communicate to jira through xmlrpc. There are two things I couldn't do until now: *1.* Add attachments to an issue. I am using the class * org.codehaus.swizzle.jira.Issue* and the method *org.codehaus.swizzle.jira .createIssue(issue)* to create the issue. *2.* Get a list of jira users. Is there a way to do those things? Is there somebody doing something similar out there (xwiki site that wraps the jira functionality)? Thanks, Abel
