oData output inconsistent across browsers

Hi experts.

I am going through the SAP Press OData and SAP Netweaver Gateway book and am trying out the examples in my AWS demo instance. The book uses service ZGWSAMPLE_SRV and says that the query "/sap/opu/odata/sap/ZGWSAMPLE_SRV/BusinessPartnerCollection?$filter=startswith(CompanyName, 'S')" will return a list of the companies.

However in IE and Firefox what I get back is a page saying that this is a feed and the output is limited to the BP ID only:

And in Chrome I get XML with far more data then I expect:

Can anyone tell me what I am doing wrong? Or is this the expected output and the book was just summarizing the output?

Thanks

Dave
