The OA4MP Server has both GetCert and GetProxy Endpoints available at the same time, but the MyProxy Server in its backend can only be configured to return '''either''' EEC '''or''' Proxy Certificate. Therefore caution must be taken to only expose the GetProxy Endpoint in case the backend MyProxy is configured to issue Proxy Certificates, otherwise you will end up getting EECs from the GetProxy Endpoint instead of the desired proxy.

'''Note:''' Do not use the GetProxy Endpoint when the backend MyProxy Server is configured as a CA issuing End Entity Certificates!

* Step 1 : As mentioned above, the key and CSR generation has been moved away from the OA4MP Client into the Server. The ''verifyAndGet'' method creates a new keypair and saves the resulting private key and CSR into the transaction. The proxylifetime, voname and vomses are also stripped off here from the request and saved in the transaction.

The original OA4MP uses ''MyX509Certificates'' as a container to transmit and receive certificate chains. With the extension of GetProxy Endpoint, this container class is no longer sufficient to transmit proxies around, because it cannot hold the proxy's private key. A new container under the name of ''MyX509Proxy'' has been implemented which extends ''MyX509Certificates''.

The ''ProxyUtil'' class is hold a set of static methods used for proxy transformation and generation. This class works with the aid of a newly introduced dependency: [https://github.com/eu-emi/canl-java/ canl-java]. At the time of this writing the canl version integrated was version 2.2.0.

A new request server called ''PPServer2'' (Protected Proxy Server 2) has been added after the model of ''PAServer2'' used for GetCert Requests. The new ''PPServer2'' class sets [[#Protocol Specification | GetProxy request parameters]] and creates a ''MyX509Proxy'' out of the response.
