For such kind of datasets it will be better user in-direct export

Export to csv-xls, or html-xls

Grab latest package
dhtmlx.com/x/download/regular/gr … l-java.zip

and check
grid-excel.war\WEB-INF\src\CSVGenerator.java
grid-excel.war\WEB-INF\src\HTMLGenerator.java

Hello guy,
Tested (CSVGenerator,HTMLGenerator, …). I’m using version 3.0 DHTMLX Pro with the latest version of export/java… but still giving the same error. :neutral_face:

Please make a test with the java version and look if the same error appears.

Look this error: java.net.URLDecoder.decode (Unknown Source). Can not seem to apply in url decode large.

Hi,
sorry for the delay in answerring.
It looks like incoming is too big but server configuration denies so much incoming data in POST method.
I guess you have to configure server to set maxPostSize option bigger.

Thank you! Fully functional. =]
