Hi,
Jira supports links from issues to other issues and also links to external Web pages. For example:

The Issue.getIssueLinks() method appears to only retrieve links to other issues and not the link to the external Web page. E.g., the following code:
System.out.format("Start dumping links for issue %s%n", issue.getKey());
for (IssueLink il : issue.getIssueLinks()) {
System.out.format("- Issue link: %s%n", il);
}
System.out.format("End dumping links for issue %s%n", issue.getKey());Causes the following to be printed:
Start dumping links for issue OPP-14
- Issue link: IssueLink{targetIssueKey=OPP-7, targetIssueUri=https://deljirauat/rest/api/2/issue/54357, issueLinkType=IssueLinkType{name=Relates, description=relates to, direction=OUTBOUND}}
End dumping links for issue OPP-14
Using the Java REST Java Client (I am using version 5.1.6):
- How does one retrieve links to Web pages?
- How does one add a link to a Web page to an issue?
Thanks,
James
