Is there an OData Server Library for Java or PHP to EXPOSE OData?

I am wondering if there is or why there isn't a ADO.NET Data Services Server Library for Java?

I need to expose a database from a Java Server but i开发者_StackOverflow社区 only see Microsot providing clients for java not server parts.

How is that an open standard when you need .NET/Windows to expose it?

Thanks for any pointers to that. Same interesting for PHP as well.

Check out odata4j - pure java odata implementation - both client and server side.

Now there is one available for PHP: OData Producer Library for PHP

There is also an Apr 6, 2010 sourceforge.net project, od4j.

SAP just releaseed their OData sdk on github, you can check here: https://github.com/SAP/cloud-odata-java

Apache have one incubating project for OData, you can check here: http://olingo.incubator.apache.org/

Apache Olingo will be the first to support OData 4.
