I have a question related to creating a custom link type, where the source is a OSLC url (string) and the target is a work-item. Later I should be able to fetch those links for a given work-item using plain java client.

The plugin.xml file is:
<code>
<?xml version="1.0" encoding="UTF-8" ?>
<?eclipse version="3.4"?>
<plugin>
    <extension point="com.ibm.team.repository.common.linkTypes">
        <linkType constrained="true" id="com.test.test_link_type">
            < source >
                <endpoint displayName="Test Link" icon="images/test_link.gif"/>
            </ source >
            <target>
                <endpoint displayName="Work Item">
                    <itemReferenceType itemTypeName="WorkItem" packageURI="com.ibm.team.workitem"/>
                </endpoint>
            </target>
        </linkType>
    </extension>
</plugin>
</code>

Can anyone tell me whether the XML file is correct and is it possible to create a link where one of SOURCE/TARGET is not a work-item.

I am successfully able to creat a link using the following code and also I am able to see the link on the work-item from the eclipse client.

<code>
    ILinkManager linkManager = (ILinkManager) repository.getClientLibrary(ILinkManager.class);

    URI testUri = new URI("1234");
    ILink newLink = linkManager.createLink(
        TEST_LINK,
        IReferenceFactory.INSTANCE.createReferenceFromURI(testUri, testDisplayName),
        linkManager.referenceFactory().createReferenceToItem(workItem.getItemHandle()));

    linkManager.saveLink(link, new SubProgressMonitor(monitor, 50));
</code>

But I am not able to query for the links for the given work-item. Below is the code that I am trying to use to fetch the links for the given work-item.
   
<code>
    IReferenceFactory referenceFactory = linkManager.referenceFactory();
    IReference workItemReference = referenceFactory.createReferenceToItem(workItemHandle);

    ILinkQueryPage linkQueryPage = linkManager.findLinks(TEST_LINK, workItemReference, monitor);

    for (ILink link : linkQueryPage.getAllLinksFromHereOn())
    {
        System.out.println("Source: " + link.getSourceRef());
    }
</code>

Even-though the links are created successfully for the work-item, none of those links are returned while fetching the links. It is always empty. Please correct me if there are any issues with the above mentioned code.

Thanks,
Vijay
