Need help with Content.getAsFile() (and UrlContent objects???)

Hello,

I am really having trouble getting this method call to work. Java, DFS 6.5, separate tiers. Any help is appreciated!

I can get as far as calling Content.canGetAsFile() successfully, but the next call which should get the actual file fails with no errors. I then tried using Content.canGetAsByteArray(), which also returned true, so I tried Content.getAsByteArray[] and finally received an error:

com.emc.documentum.fs.rt.ServiceInvocationRuntimeException ] Current method should be overridden: "class com.emc.documentum.fs.datamodel.core.content.UrlContent"com.emc.documentum.fs.rt.ServiceInvocationRuntimeException: Current method should be overridden: "class com.emc.documentum.fs.datamodel.core.content.UrlContent"
    at com.emc.documentum.fs.datamodel.core.content.Content.throwOverrideException(Content.java:331)
    at com.emc.documentum.fs.datamodel.core.content.Content.canGetAsFile(Content.java:157)
    at com.emc.documentum.fs.datamodel.core.content.UrlContent.canGetAsByteArray(UrlContent.java:86)

This is pretty confusing. First, why am I receiving UrlContent objects instead of a more usable type like FileContent or BinaryContent? Second, what does this error mean and how can I get around it? The object I am trying to return is a normal 183kb .PDF file on a local server.

This is the code I am using to retrieve the object:

        ObjectIdentity<ObjectId> objIdentity = new ObjectIdentity<ObjectId>(new ObjectId(sObjId), sRepository);

         ObjectIdentitySet objectIdSet = new ObjectIdentitySet();
        objectIdSet.addIdentity(objIdentity);

         DataObject dataObj = null;


         try {
             ServiceFactory sf = ServiceFactory.getInstance();
            IObjectService os = sf.getRemoteService(IObjectService.class, context);

                PropertyProfile           pp = new PropertyProfile(PropertyFilterMode.ALL);
               ContentProfile            cp = new ContentProfile();
               OperationOptions         oo = new OperationOptions();
               ContentTransferProfile ctp = new ContentTransferProfile();

             if (includePermissions) {
                //logger.debug("Include permissions (object).");
                PermissionProfile permissionProfile = new PermissionProfile();
                permissionProfile.setPermissionTypeFilter(PermissionTypeFilter.ANY);
                oo.setPermissionProfile(permissionProfile);
            }

             ctp.setTransferMode(ContentTransferMode.MTOM);
            cp.setFormatFilter(ff);
             oo.setContentTransferProfile(ctp);
            oo.setPropertyProfile(pp);
            oo.setContentProfile(cp);
            oo.setProfile(cp);

             DataPackage dataPackage = os.get(objectIdSet, oo);
            if (dataPackage.getDataObjects().size() > 0)
                dataObj = dataPackage.getDataObjects().get(0);
        }
         catch(ServiceInvocationException exc){
             throw new Exception(exc) ;
         }
        catch(CoreServiceException exc){
             throw new Exception(exc) ;
         }
        catch(ServiceException exc){
             throw new Exception(exc) ;
         }
        return dataObj;

And this is the code I am using to try to pull out the contents. It fails on the bolded lines. In order to actually "see" the error caught and logged, I have to comment out the File attempt and try the ByteArray. The File produces no errors but causes the server to halt:

if (dataObj.getContents().size() > 0) {
Content contentObj = dataObj.getContents().get(0);

            if (contentObj.canGetAsFile()) {
                File file = contentObj.getAsFile();
            }

if (contentObj.canGetAsByteArray()) {
new ByteArrayInputStream(contentObj.getAsByteArray());

}

I have not figured out what the original problem was, but using the newer 6.5 SP1 DFS .jars has fixed my problem.

Thanks for looking.

Hi... bhannemann

I have a problem similar to yours ...

reusing your code but in .Net C#, I do not load the Contant and the error is that you get ... you know you can be going ....

gcamou,

You need to make sure you set the ContentProfile.setFormatFilter(); property (see my code). This allows you to specify a content rendition to return. If you do not set this, no content is returned by default.

gcamou

hello again ...

First I want to thank you for having responded so quickly ...

and add the ContentProfile but the result is the same

Code

ObjectIdentity objIdentity = new ObjectIdentity(new ObjectId(documentumId), _repository);

ObjectIdentitySet objectIdSet = new ObjectIdentitySet();
objectIdSet.AddIdentity(objIdentity);

DataObject dataObj = null;

            try
            {
              PropertyProfile propertyProfile = new PropertyProfile(PropertyFilterMode.ALL);
                ContentProfile contentProfile = new ContentProfile();
                OperationOptions operationOptions = new OperationOptions();
                ContentTransferProfile contentTransferProfile = new ContentTransferProfile();

                PermissionProfile permissionProfile = new PermissionProfile();
                permissionProfile.PermissionTypeFilter = PermissionTypeFilter.ANY;
                operationOptions.PermissionProfile = permissionProfile;

                contentTransferProfile.TransferMode = ContentTransferMode.MTOM;
                contentProfile.FormatFilter = FormatFilter.ANY;
                operationOptions.ContentTransferProfile = contentTransferProfile;
                operationOptions.PropertyProfile = propertyProfile;
                operationOptions.ContentProfile = contentProfile;

DataPackage dataPackage = objectService.Get(objectIdSet, operationOptions);

                dataObj = dataPackage.DataObjects[0];
            }
            catch (Exception ex)
            {
                throw ex;
            }

Content contentObj = dataObj.Contents[0];

return contentObj.GetAsByteArray();

another idea ...

thanks....

Oleg

Correct, this issue has been fixed in DFS 6.5 SP1.

gcamou

thank you very much Oleg This review at this time .....

one ask, you know how to increment the quota, use the MaxReceivedMessageSize

thanks...

I have not been as fortunatate solving this problem. The problem I'm having is the objectservice.get() comes back with a URL. Then when I execute the any flavor of FileContent.getAsByteArray or FileContent.getAsFile, I get either an HTTP 500, or if I execute the canGetAsByteArray, I get an exception saying that this should be overridden...

At this point I would appreciate any assistance or ideas that anyone has. Code below:-

public String getDocument(DmsDocument document, String user) {String error =

"";

final Long sizeLimit = new Long(5120);ContentTransferProfile transferProfile =

new ContentTransferProfile();

if (sizeLimit.compareTo(document.getObjectSize()) > 0) {transferProfile.setTransferMode(ContentTransferMode.

BASE64);}

else {transferProfile.setTransferMode(ContentTransferMode.

MTOM);}

ObjectId objectId =

new ObjectId(document.getObjectId());ObjectIdentity objectIdentity =

new ObjectIdentity(objectId, dmsConfig.getRepository());

try {DataObject dataObject = getDocumentWithContent(objectIdentity,

null, transferProfile);

if (dataObject != null) {Content resultContent = dataObject.getContents().get(0);

if (resultContent instanceof UrlContent) {UrlContent urlContent = (UrlContent)resultContent;

document.setBData(urlContent.getAsByteArray());

}

else if (resultContent instanceof DataHandlerContent) {DataHandlerContent dhcContent = (DataHandlerContent)resultContent;

document.setBData(dhcContent.getAsByteArray());}

else if (resultContent instanceof FileContent) {FileContent fileContent = (FileContent)resultContent;

document.setBData(fileContent.getAsByteArray());

}

else if (resultContent instanceof BinaryContent) {BinaryContent binContent = (BinaryContent)resultContent;

document.setBData(binContent.getAsByteArray());

}

}}

catch(Exception e) {error = e.toString();

cat.error(error);e.printStackTrace();

return error;}

private DataObject getDocumentWithContent(ObjectIdentity objectIdentity, String geoLoc, ContentTransferProfile transferProfile)

throws ServiceException {

transferProfile.setGeolocation(

null);

serviceContext.setProfile(transferProfile);

ContentProfile contentProfile =

new ContentProfile();contentProfile.setFormatFilter(FormatFilter.

ANY);contentProfile.setPageFilter(PageFilter.

ANY);

contentProfile.setPageModifierFilter(PageModifierFilter.

ANY);OperationOptions operationOptions =

new OperationOptions();operationOptions.setContentProfile(contentProfile);

ObjectIdentitySet objectIdSet = new ObjectIdentitySet();List<ObjectIdentity> objIdList = objectIdSet.getIdentities();

objIdList.add(objectIdentity);

DataPackage dataPackage =

objectService.get(objectIdSet, operationOptions);

DataObject dataObject = dataPackage.getDataObjects().get(0);

Content resultContent = dataObject.getContents().get(0);

System.out.println("Type of returned content is: "

+ resultContent.getClass());

return dataObject;}
