[jira] [Commented] (PIVOT-406) Ensure that java_arguments param is properly set for Large Data demo

["Sandro Martini (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIVOT-406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13154273#comment-13154273 ] 

Sandro Martini commented on PIVOT-406:
--------------------------------------

512 MB of RAM aren't enough for the 10e5 version of the data file ... I just tried the Web Start version with a JRE 6 at 32 bit, and with a 1024 MB all works.
This is an extract from the related (dynamically generated) jnlp file:
		<java version="1.6+" href="http://java.sun.com/products/autodl/j2se" 
		  initial-heap-size="256M" max-heap-size="1024M"/>
		<jar href="lib/pivot-core-2.0.1.jar"/><jar href="lib/pivot-wtk-2.0.1.jar" main="true"/><jar href="lib/pivot-wtk-terra-2.0.1.jar"/><jar href="lib/pivot-demos-2.0.1.jar"/><jar href="lib/svgSalamander-tiny.jar"/></resources><application-desc main-class="org.apache.pivot.wtk.DesktopApplicationContext"><argument>org.apache.pivot.demos.million.LargeData</argument><argument>--center=true</argument>
<!--		<argument>--basePath=pivot-demos/assets</argument> -->
		<argument>--basePath=http://localhost:8080/pivot-demos/assets</argument>
				</application-desc><update check="background"/>
		</jnlp>

note that at the moment even the basePath argument has been fixed by hand in the jnlp page ... I have to try to make it work in the standard distribution, and in the live Pivot web site.

> In previous releases, the HTML for the Large Data sets demo included a JVM argument to increase the heap size for the demo applet. The default heap size for the JVM on some platforms is not sufficient to handle the large number of rows displayed by the demo. This argument was lost in the transition to the new site format. 
> The following applet param should be added to this demo:
> java_arguments:"-Xms512M"
