It's been several months since you posted, so I'm not sure whether you still need this, However, I'm trying to do the same thing -- migrate only the new or changed forms between servers using the RepositoryService APIs, and I think I've found something that works.
When I drag a resource into an application in ES2, the resource ends up with a ResourceProperty collection. When I add a resource using the writeResource API call, however, this ResourceProperty collection is not created. After some trial and error, I found that I could create a ResourceProperty collection when I create the Resource itself and then use the writeResource API call to add the resource to an application.
The ResourceProperty that makes the resource visible is in the "System" namespace. It's named "PRIMARY" and should have the value of
"true".
I use the .NET APIs, not the Java APIs, but I think the concept would be the same. In the code below, "ES2RepositoryService" is a web reference to the LC ES2 repository service and "OriginalBlob" is the Blob read in from the region from which I'm migrating.
Dim ES2LC As New ES2RepositoryService.RepositoryServiceService
ES2LC.Credentials = New System.Net.NetworkCredential(<logon>, <password>)
Dim NewBLOB As New ES2RepositoryService.BLOB
NewBLOB.contentType = OriginalBLOB.contentType
NewBLOB.binaryData = OriginalBLOB.binaryData
Dim NewContent As New ES2RepositoryService.ResourceContent
NewContent.dataDocument = NewBLOB
NewContent.size = NewBLOB.binaryData.Length
Dim NewResource As New ES2RepositoryService.Resource
NewResource.id = New ES2RepositoryService.Id
NewResource.lid = New ES2RepositoryService.Lid
NewResource.content = NewContent
NewResource.name = <resource name>
NewResource.description = <resource description>
'add properties
Dim testProps(0) As ES2RepositoryService.ResourceProperty
Dim newProp As ES2RepositoryService.ResourceProperty
'this one makes it visible in Workbench
newProp = New ES2RepositoryService.ResourceProperty
newProp.name = "PRIMARY"
newProp.namespace = "System"
newProp.value = "true"
testProps(0) = newProp
NewResource.resourceProperties = testProps
ES2LC.writeResource(<new resource path>, NewResource, Nothing, Nothing)
Setting this "PRIMARY" property seems to be the trick to making the resource visible under the application in Workbench.
When I drag a resource in, many other resource properties are generated as well, and these can be added just as the "PRIMARY" property was. In my case I saw the following in the resourceProperties collection:
In the "System" namespace:
LASTUPDATEDBY - name of the last user who updated the resource
PRIMARY - "true"
VISIBILITY - this had the value of "Private"
PUBLISHEDSTATUS - this was valued as "InProgress"
RESOURCETYPE - this had the value of "TLO"
Deployment Version - Nothing
Deployment ID - Nothing
In the "Custom" namespace:
extension "xdp"
scope "Far"
relative-path
absolute-path
application-name
isApplication "false"
version
If the resource is an XDP that has a relationship to another file (an XSD, for example) another ResourceProperty is created where
the value is the path to the related file and the namespace is "Reference".
