A quick way to log all SSL traffic is to startup java with: -Djavax.net.debug=all Or set it as a system property: System.setProperty(“javax.net.debug”, “all”); Brace yourself. Standard out gets NOISY if you do this! (*Note: only logs SSL traffic and SSL debug info (handshakes, etc). Regular sockets are not logged.)
EDIT: Brian Slesinsky just documented the protocol (by reverse-engineering the code): https://docs.google.com/document/d/1eG0YocsYYbNAtivkLtcaiEE5IOF5u4LUol8-LL0TIKU/edit First, GWT-RPC protocol is asymmetric so that it’s always optimized for the client-side: fast to deserialize something coming from the server, and fast to serialize something to send to it. It’s obviously not binary, as you suspected, but text-based. client-to-server protocol is pipe-delimited … Read more
Since HAIFA is dead now there are no equivalent frameworks for SOAP web services in Haskell now. So I would advise you to use some bunch of frameworks. May be Yesod + shoap will be suitable. I think such a tendency in domain of SOAP WS frameworks in Haskell because of smooth transition to REST/JSON … Read more
Short answer: RPC is the protocol. The socket provides access to the transport to implement that protocol. RPC is the service and protocol offered by the operating system to allow code to be triggered for running by a remote application. It has a defined protocol by which procedures or objects can be accessed by another … Read more
You mean your code works fine but you see this exception in logs? Exception basically means that compilation cache failed to load for some reason. Most likely cache has become corrupted for some reason, so try to remove folder gwt-UnitCache from your project, this should help.
No, you cannot use a primitive type as either the request or response. You must use a message type. This is important because a message type can be extended later, in case you decide you want to add a new parameter or return some additional data.
Suddenly I feel proud to be a British Citizen… are you ready? Good: HMRC (the lovely people who take our tax off us) provide a fully documented API, see here, for filling in just about every form they have. Not only that, but they define a whole set of schemas and everything available here: http://www.cabinetoffice.gov.uk/govtalk/schemasstandards.aspx … Read more
Here’s my take. Although coming from a Java standpoint, I actually prefer REST. SOAP envelope with multiple namespaces and its complex structure is abomination. It tries to solve mostly imaginary problems, and doesn’t solve anything efficiently. Only thing about SOAP I’ve found useful is that it has standards for authorization and errors. On the other … Read more
I don’t think sockets are really overkill. The alternatives all have their own problems and sockets are far better supported than named pipes, shared memory, etc., because almost everyone is using them. The speed of sockets on local system is probably not an issue. There’s Apache Thrift: http://incubator.apache.org/thrift/ There are a few RPC implementations wrapped … Read more
