Getting Empty Page(white Page) with out any screen fields when save Button

[Former Member]

Hi all,

We are developing WebDynPro Application in Java environment. In that application after selection of some records

from the table view and press the SAVE button it is calling RFC and saves the data.

again I am taking some more records from the table view and again saving the records (calling same RFC )

it is not calling RFC from the UI. Before that it is going to empty page and the server is coming to IDEAL stage(yellow color).

all other functions are working fine. I checked the local J2EE server log and found that it is OUT of Memory and posted the log for your ref.

I am trying with all sort of way Till now The problem has not solved.

I am working in WebvdynPro for the past 3 years Till now I did n't get this type of problem .

kindly halp me with suggestion to p[roceed further.

I checked the sdn i found I have to configure in the Configration tool for J2EE Engine.

If any guys come accross the same type of problem pl send suggestion with details.

Thanks in Advance

srini

Hi,

Check the following areas if they exists in your program.

repeated calls in the wdDomodify method

calculated attributes which access the set and get of the same. Which may lead to a deadlock scenario.

Hi Srini,

there may be two reasons for this exception:

1. You are using some code probably a loop which is taking too much of time to execute.this has already been suggested to you.so please verify flow of code execution.

2. Your machine is out of memory.So Please try to free up pc memory and use only one application while deploying application.

I have also faced out of memory exception and in my case second reason was applicable.

Thanks.

Hi

I too encountered the same problem and finally it was due to an infinite loop in the program as Balaram said....

so check your code and see whether any infinite loop is running.

Hello Sri,

It seems there is some infinitite loop involved in your code.check the code once.if you will not find anything,post the code which makes RFC calls.
