We are a project management company and our people are all educated and experienced developers. We love to code, but we even more love to guide projects to success. We usually get an A++ rating for our project management on the different platforms we work on.

For now we have a nice little project. We need to implement a link with an API Server to get all kind of financial data of. Because of the kind of data, all messages will flow over HTTPS and be signed with encrypted messages to verify if something is modified during its way from client to server.

The server is using Java with the #Spring framework. We already built several clients in languages other than Java but that is nearly impossible and there is no support from the API owner. They just don’t know how it works because it is an Spring Framework generated #API Server. Therefor we are requiring you to have strong knowledge of generating an API client with the Spring Framework for us. An API client has to be generated by importing a WSDL which we received from them.

So with the WSDL an client has to be generated which should be able to send commands to the API Server (using “OASIS Open” and “WSS” for security signing the message). We have a PFX file containing the public key and private key which are required for the signing process.

When the API Client works, we will require you to build an extra page for us inside the API client which makes it possible for us to do simple requests like:

/apiclient?get=document&details={…}

The page should then convert it into a signed API message and send it to the server, fetch the response and send it back to the requester. In that way we can do once the complex API implementation and inside our network use it in a very simple way with GET or POST-request.

We are only looking for people with EXISTING EXPERIENCE who can implement this using EXISTING KNOWLEDGE. We are NOT LOOKING for people which will spend many hours trying, because we already passed the phase of "die trying".

SPRING Framework. 'Sprint' is a typo, but cannot change the title anymore at this point.
