Hi Stephan, thanks for your kind reply. I think you correctly described the issue I'm having. It would be great if the JPA processor could support the "hasStream" flag. At the moment, my JPA entity has a field defined as follows
@Basic(fetch = LAZY) @Lob @Column(length = 4001) << this is required for a database issue, which requires length > 4000 bytes private byte[] binaryData; It would be great if anyone could clarify whether the stream feature is implemented for JPA processor Thanks a lot Regards Vincenzo 2013/12/6 Klevenz, Stephan <[email protected]> > Hi Vincenzo, > > In general Olingo support creation of media resources as described here: > > http://msdn.microsoft.com/en-us/library/dd942074.aspx > > A precondition is that the EntityType is flagged with the HasStream > attribute: > > <EntityType Name="MyMediaResource" m:HasStream="true"> > > I am not sure if this feature is already supported by the JPA processor. > Maybe Chandan can clarify this. > > If not then I recommend to open a feature request here: > > https://issues.apache.org/jira/browse/OLINGO > > Regards, > Stephan > > On 05.12.13 18:33, "Vincenzo Turco" <[email protected]> wrote: > > >Hi all, > >I am using Olingo with great satisfaction in my current project and would > >be really grateful if I could get any help on an issue I'm facing. > >Apologies in advance if this is not the appropriate DL for this kind of > >questions. > > > >I am successfully exposing my database using an ODataJPAServiceFactory. > >One of the entities in my db represents a "File" and has a property of > >type > >Edm.Binary which at the db level is a BLOB.
