Hello good people,

Am working on a RESTFul API backend to be consumed from an android app.

Its hosted here 

http://www.piemicrosystems.com/bisa-rest-api/api/rooms

Now my problem : The above url when accessed is supposed to return a json list containing 

a list of rooms. Now this works perfectly on my local server without a problem but once hosted the api doesn't return data until i restart my tomcat server online.

Upon restart, it works perfectly again for some minutes and stops. It returns the json alright but without the rooms.

Any one willing to help can send me his/her bitbucket id so that i can share the code with him/her.

Any help?

Best Wishes,

Edward Pie

Have you fixed the problem?

If not my bitbucket ID be 'stee' without the quotes.

Thanks Sadik, I fixed it with hibernate c3p0. Apparently, mysql closes open connections at regular intervals so i just used it to make it stay open.

Edward, 

I'm interested to know what happens to your memory after the app is subjected to a little bit of load for say 30 minutes. Does the memory stay constant, or does is increase steadily?

I did a benchmark and I found that the memory usage stays constant. The magic had already been done in the c3p0 lib. Am sure it closes the connection when left idle and reopens from a pool when neccessary. That way, nothing is unnecessarily allowed use the memory for breakfast.

Tehehe. Awesome!

Interesting. Good to know, I hope it logged that fact. - Nii Nai Sent from Yahoo Mail on Android
