Jira Gadget: Get all Issues of specific type

I'd like to create a new chart开发者_Go百科 gadget for jira using jfreechart. To collect all the information I need for the chart, I need all issues of a certain issue type. How do I look them up in my java class? More specific, if I want to use a jquery I need the currently logged in user. How do I get the appropriate user object?

Found the solution. First get those two objects via constructor injection:

final SearchService searchService
final JiraAuthenticationContext authenticationContext

Then execute your query like that:

            final SearchResults results = searchService.search(authenticationContext.getLoggedInUser(), query,
                PagerFilter.getUnlimitedFilter());
        return results.getIssues();
