Well... for small java programs, may be. But if you running a web application with a decent memory requirements, more often than not you will have to change the default heap size. Just checked it on the sun's site, default value for maximum heap size before J2SE1.5 is 64MB which I am not sure is good enough for most production stacks.

Well in most cases the default heap size does good enough. In some cases we may have to increase it. But in case this too doesn't work, try profiling your code. > > > On 11/14/06, Caldarale, Charles R <[EMAIL PROTECTED]> wrote: >> >> > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] >> > Subject: Tomcat Out Of Memory >> > >> > We are running Tomcat 4.1.18 on RedHat ES3 using JDK 1.4.2_02. >> > What is causing the error message below and What can I do to solve it? >> >> Start by reading the FAQ: >> http://tomcat.apache.org/faq/memory.html >> >> You will need to collect more information. >> >> - Chuck >> >> >> THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY >> MATERIAL and is thus for use only by the intended recipient.
