Timeout after 5th minute on UI if no response returned from server

[naveenkoneru]

1. jboss-4.2.3.GA

2. jdk1.6.0_105

3. jboss-seam-2.1.1.GA

4. jsf-api-1.2_09

We have a jsf application which was deployed in jboss-4.2.3 server

When I click a button in the UI of our application, it gets the data from oracle database and try to create an excel sheet and finally it gets downloaded..

My issue is, if my JPA query takes more than 6 minutes to get the whole data from database (exceptional case : client which huge data) I am facing the error attached..

Before the data gets retrieved/before the excel was made I am getting "A system error has occurred. If this continues, please contact your system administrator or support representative with the error code: {502}" on the UI after 5th minute

This seems to be related to some response time from application server..

Is there any chance to increase that time ??

Hi,

What is the error has been encountered at server.log file at the time of the issue?  Paste the Error stack trace here ?

[naveenkoneru]

There are no errors in server logs..

There is some error has been encountered in the background wither server.log or your application log or DB log file.

A system error has occurred. If this continues, please contact your system administrator or support representative with the error code: {502} ..

this the generic error. The root cause is different. Without reproducing the error in the any of the log stack trace difficult to answer what's the issue is going on?  Is it Something DB timeout? verify that the database server side timeout value is larger than the timeout period in JBoss

The thread which brings data from database is running in the backend without any breaks or errors... Nothing wrong with DB server.. But by the time the data was made into excel in back end we are getting this exception in UI( immediately after 5th minute)..

- Check the data coming from DB server is properly  populated or not on model object which shows all data in UI to render it.

- Check  all the data is getting properly populated in your excel file? Is there type mismatch or length or of data. Check your application code is developed such a fashion that all the image format data like (.gif/.jpeg/.png..etc) should accept or not?

Here i think there is no such relation with jboss app server.
