Swing client for DWR

[ajmalhinas]

Hi all

I am using DWR with my web application. It is really do a good job. But i need to provide swing client for some part of
my application due to slow response of ajax. I don't like to write another web service for it because already dwr is doing the same
think. Are there any java library available to use dwr with swing clients. Any workarounds Pls help me.


Thank you

Your question doesn't make any sense to me.  DWR serializes Java into
JavaScript and JavaScript into Java.  If you plan on using Swing (which
is Java) then there is no reason to use a library like DWR.

I have no idea what you mean by "slow response of ajax".  If you are
having a problem with slowness you are probably doing something
incorrectly.  You may want to take a look at our troubleshooting page -

I will explain little bit more. We developed a web application it  uses  DWR internally to  supply the data needed by  ajax components(I believe after the completion of page loading dwr supply only the data not data+html+etc... . If i am wrong than pls correct me)  . We need to provide specialized hardware support for some parts of my application. It requires a client in swing or in some other desktop technology.  We actually developed a two tier client, it directly connects the database. But  it created problem with hibernate caching due to the truth it bypass the hibernate cache. So now our clients are forced to do the communication through the web application. It requires us to write web services for our client. But i think it is a redundant work because our web application's ajax components are loading the data when user do some action in the page (ie. When a user enters customer id then loads all relevant data ),the same think exactly we need to do with Swing clients.  

If we can do something  with JavaScript then  it can be done with Swing right?
DWR latest version have support for JSON-RPC i think if pure dwr may not help me then JSON-RPC can be used.
But i do not find any neat java library for JSON-RPC of DWR. pls if you know help me. Also i am expecting your kind advice on this problem.

I am sorry but I am not quite following you and this is really beyond
the scope of DWR.

If all you want to do is make a remote call from your swing applet than
I am not sure why you would mess with the serializing/deserialization of
working with JSON or JavaScript.

You can make remote calls from your applet (RMI).  I haven't worked with
applets in a long time but I would recommend asking your question on an
message board for applets are searching the web and find the best way to
make remote calls from an applet.

I may be answering to the wrong question, but if this is what you
have:
  webapp client -> DWR server
and you also want to do:
  Swing client -> DWR server
then yes, you should be able to use DWR's JSON-RPC feature. DWR
only provides the JSON-RPC server and you need to use some other
product in the Java client. A google search:
http://www.google.se/search?q=%22java+client%22+json-rpc
comes up with f ex:
http://code.google.com/p/json-rpc-client/

Check this out and tell us how it goes!

Best regards

Yes i exactly want to do this. I will check the json-rpc-client library with dwr and post the result here.

RMI can be used only with java clients it is not a generic technology my client may be in .net or c++ also. I can use web services but dwr already have json-rpc  so i think i can use it instead of web services.

That makes more sense.  Hope that library Mike recommended works for you.
