<p><span style="color:rgb(40,40,40);font-family:'Source Sans Pro', sans-serif;">We have the BIRT viewer (version 4.3) installed and deploy report projects to Tomcat 6.0. </span></p>
<p><span style="color:rgb(40,40,40);font-family:'Source Sans Pro', sans-serif;">We have a table report reading from a large JSON object as script data source. Json object have almost 30,000 records, and the total size are 16MB. </span></p>
<p> </p>
<p><span style="color:rgb(40,40,40);font-family:'Source Sans Pro', sans-serif;">It takes about 10mins to load the json objects, but before loading complete, progress bar disappear. In tomcat console and log, there is no error message. </span></p>
<p> </p>
<p><span style="color:rgb(40,40,40);font-family:'Source Sans Pro', sans-serif;">i checked the session settings in viewer.properties, </span></p>
<p>viewer.session.timeout=0</p>
<p> </p>
<p> </p>
<p>and in tomcat, the http session time out is 30 mins. </p>
<p> </p>
