I am getting an Exception in thread "HSQLDB Connection @3c50507"

java.lang.OutOfMemoryError: Java heap space, when running a JSP.

what is the thing that is out of memory? eclipse, HSQLDB or Tomcat?? i am using all that in a Mac OS X 10.7.4

When i start HSQLDB, then i get by console this exception:

[Server@122ce908]: From command line, use [Ctrl]+[C] to abort abruptly
