When I install the application on Windows Server 2008, I get an out of memory exception, because of the low heap size. How can I pass JVM arguments to increase the heap size (-Xmx) in this scenario? Is there any way to specefy jvm arguments to be called when creating the native bundle with Inno Setup? 回答1: There is no way to do in via Inno Setup, because

问题 I'm unable to draw minor grid lines, it is possible to do so in JavaFx 2.2? In my case the grid and the graph moves so I cannot use a static image to generate the minor grid (live graph as shown in this example here).
