Filenet storing and getting objects from store - Java Step Processor

Question

I'm implementing Filenet Java Step Processor. I have to get a document from object store, moddify and store modified version to the same object store. I have a working applet for tests. I can't ask user for additional sending login and password, I have to work with VWSession object. Document which I have to get is send as step attachment. I know how to get attached document ID. How to get document by ID from Java Step Processor using VWSession object as my connection point to Object Store?

Answer 1

Getting the user credentials is not that difficult. In the stepprocessor java module just dop the following:

String userName = controller.getDataStore().getServerCredentials().getUserId();
String userPwd = controller.getDataStore().getServerCredentials().getPassword();

For getting the document you mean, normally you will not get that over a VWConnection but over a Content engine connection.

getting your document via ID:

Factory.Document.fetchInstance(objectStore, guid, null);

Hope it helps

Get an ObjectStore instance (Get the domainId from the VWSession, and construct the domain using the Connection from VWSession also) and pass the Attachment to the method below:

private String getIdFromAttachment(VWAttachment att, ObjectStore os) {
    if (att.getLibraryType() != 3) {
        String libtype = String.valueOf(att.getLibraryType());
        throw new VWException("hk.ibm.ecm.cpa.uwfcustomcomponent.InvalidLibraryType",
                "Cannot convert object from non-CE repository, type {0}.", libtype);
    }

    String attId = att.getId();
    switch (att.getType()) {
    case 3:
    case 4:
        VersionSeries vs = (VersionSeries) os.getObject("VersionSeries", attId);
        vs.refresh();
        String ver = att.getVersion();
        return getIdBasedOnVersion(vs, ver);
    default:
        return attId;
    }
}

private String getIdBasedOnVersion(VersionSeries vs, String ver) {
    if (ver == null) {
        Document current = (Document) vs.get_CurrentVersion();
        current.refresh();
        return current.get_Id().toString();
    } else if ("-1".equals(ver)) {
        Document released = (Document) vs.get_ReleasedVersion();
        released.refresh();
        return released.get_Id().toString();
    } else {
        return ver;
    }
}
