Data import questions

Hi all fellow users,
I have encountered a problem upon importing my data.
When I exported my entire study and tried to import it, the browser just wouldn't even load the page.
Then when I tried cutting the XML file small and made it to only 1 study event, the browser popped up error message "HTTP Error 413 Request entity too large".
The importing feature only worked for me when I manually made the XML file small containing only 1 or 2 subjects. Can anybody shed some light on how this problem can be solved? Manually breaking down the clinical data XML file to smaller pieces is quite time consuming and frustrating.
thanks in advance!

  • Dear Angela,

    It sounds like you need to ensure that Tomcat and any software sitting in front of Tomcat accepts large amounts of data in requests. Are you on Windows/Linux, are you using a proxy? Your tomcat may take exception to files larger than 2MB.

    There are some configuration parameters here:
    http://tomcat.apache.org/tomcat-6.0-doc/config/http.html

    And a possibly relevant discussion here:
