We plan to implement Jira in our company and for this we must prove that regular updates from our old issue tracking system are possible. For this I am writing a Jira service that should get all the issues that have changed in the old system and create/update the issues in Jira.

For the update I have to check whether an issue has already been imported or not, thus I need to search a Jira issue by a custom field value. After studying your APIs for some hours the best I could come up with is the following code - which unfortuately tries to instatiate an interface

private Issue jiraSearchByTicketId(Integer ticketId) {
SearchRequest sr = new SearchRequest(true); // search without security checks
CustomFieldParameter cfp;

cfp.setCustomField(cfTicketID);
cfp.addValue("" + ticketId);
sr.addParameter(cfp);
try

{ List issues = issueManager.execute(sr, adminUser); return (Issue) issues.get(0); }

catch (SearchException e)

{ return null; }

}

Any ideas/hints whatsoever to do this?
