问题 When trying to launch and run a flex/java project in eclipse I kept getting a "Out of Memory Exception" and "Java Heap Space" using Eclipse, Tomcat and a JRE. While researching trying to adjust the memory settings I found three places to adjust these: Eclipse.ini The JRE Settings under Window > Preferences Catalina.sh or Catalina.bat What are the differences between setting -xms and -xmx in these different places and what does is mean? Is there any way to verify these memory settings are
