Need help with a complex Java application

internext · **Need help with a complex Java application -** 07-24-2009, 08:46 PM

I am building an application with 2 developers that is a desktop application with a lot of communication with a server. Several issues are cropping up and I want to look at how to improve things and speed up development. I'm not sure the current guys are the right people for the job. Looking for help and advice on this thanks. I expect this application to take 5-6 months to build and after that a further 18 months of improvements and refinements.

So what sort of help EXACTLY do you expect? Are you looking for freelancers or just advices?

In reality probably need some full time or part time paid developers to help with this project.

It's hard to reply, not knowing anything about your project. Is this an enterprise application? Is the server technology and architecture set? Is the Client Technology and architecture set? Are you looking for an architect or a developer (or both?)

I wouldn't mind talking to you about it, but it would be strictly a part-time project, as I have a full time job already. 8)

There are few things that you might want to consider..

1. Doing quite a few things locally before sending data to server.

2. Re thinking the application architecture to see if you can abstract few functionality to a different layer altogether.

3. Optimize the amount of data you are sending to and from the server.

Hope this helps
Cheers

Can you give me brief description of project, so that I can look into if it is possible to help you? I can help you as a part-time job only.

Thanks,

Is the desktop app Java Swing GUI? Is the server a servlet based web app? I am a full time java application and web app developer who works over the Internet from Maynard MA. Check out my credentials and projects at CDH Consult domain redirect main page

I worked on a similar project with yahoo small Biz (SiteBuilder), where the desktop app(Swing) communicated heavily with the server (linux , 4 cpu, tomcat fronting with apache) . Some things to take care of:
1. If the communication can be parallelized with multiple requests, it should be considered.
2. Do multithreading as per the scope of parallization on the client side.
3. Do a pre-launch of the desktop app to figure out the hardware resources of the client machine , and then launch the real app with optimal JVM settings for that client....u may increase JavaHeap if RAM is large, or use multiple threads for GC for multiple CPU machines.
4. Do smart caching using Java Soft References for CPU intensive resusable obects.

If u can share more insights on the project, I too may be interested in part-time freelancing, as I am working full-time currently.

don't get your hopes up. OP hasn't been seen in over a month.

Hi, sorry for the delay in getting back. We are still looking for a new full time developer, work from home. Haven't got the budget for a US developer, but can pay good rates for someone in India or other lower cost location.
