Is there a way to check the user's RAM during installation? if for example the user have low RAM a message would show that he's RAM is lower than the required and the installer will exit.
Available memory can be detected using different sources. They depends on plattform:
e.g.: Linux: parse output of "free" command HPUX: parse "top -d 1 -n 1" output Windows: Little bit tricky here, you have to use a .vbs script to determine the values. I've attached an example .vbs script. (rename it as .vbs) This you can call via cscript /Nologo systeminfo.vbs
Starting with JDK 6 you can use the ManagementFactory.getPlatformMBeanServer() to fetch several data like "TotalPhysicalMemorySize" or "TotalPhysicalMemory". But the available beans and their names depends on JVM vendor.
There is an all-Java solution. It makes use of open-source libraries that make JNI calls. I was calling systeminfo.exe and parsing the results, but XP Home doesn't have this executable!
