Recently I was put onto a project where everything was related to Java. Setting up an environment on a production server was challenging task. During the course of the project, I came across an issue that was related to the environment’s memory allocation: Java Heap Exception (out of memory error).Luckily, I figured out an ad-hoc solution I’d like to share with you here. Before getting into the details, I recommend developers follow certain J2EE programming standards. Make sure that all the resources like jdbc Connection, PreparedStatement, Statement, ResultSet, Buffers, etc. are closed. This will cut off such exceptions at run time. Yet, here are some of the work-around solutions that would work out as per the platform respectively.

I understand why it's not good idea to catch this sort of exception. As http://stackoverflow.com/questions/2679330/catching-java-lang-outofmemoryerror far as I understand, if we decide to catch it, the catch handler should not allocate any memory by itself. Otherwise OutOfMemoryError will be thrown again. So, my question is: Is there any real word scenarios when catching java.lang.OutOfMemoryError may be a good idea? If we decide to catch java.lang.OutOfMemoryError, how can we sure that catch handler doesn't allocate any memory by itself (any tools or best practices)? java try-catch out-of-memory share|improve this question edited Dec 20 '11 at 20:11 Michael Petrotta 44.6k11108151 asked Apr 20 '10 at 23:11 Denis Bazhenov 4,59752455 2 Similar questions: stackoverflow.com/questions/1692230/… and stackoverflow.com/questions/352780/… –BalusC Apr 20 '10 at 23:19 For your first question, I'll add that I will catch the OutOfMemoryError in order to (at least try to) notify the user of the problem. Previously, the error wasn't caught by the catch (Exception e) clause, and no feedback was shown to the user. –Josep Rodríguez López Oct 25 '13 at 10:14 1 There are specific cases, eg, allocating a gigantic array, where one can catch the OOM error around that operation and recover reasonably well. But placing t
in Java Everyone in java development faces java.lang.OutOfMemoryError now and then, OutOfMemoryError in Java is one problem which is http://javarevisited.blogspot.com/2011/09/javalangoutofmemoryerror-permgen-space.html more due to system's limitation (memory) rather than due to http://www.aptude.com/blog/entry/handling-java-exceptions-java-out-of-memory-error programming mistakes in most cases though in certain cases you could have a memory leak which causing OutOfMemoryError. I have found that even though java.lang.OutOfMemoryError is quite common basic knowledge of its cause and solution is largely unknown among junior error java developers. Beginners books like Head First Java doesn't teach you much about how to deal with this kind of error. You need real experience dealing with production systems, handling a large number of user sessions to troubleshoot and fix performance issues like running out of memory. If you want to be java heap space good at troubleshooting and performance analysis, you need to learn some books on Java performance and profiling e.g. Java Performance The Definitive Guide By Scott Oaks or the Java Performance by Binu John. They are an excellent resource for senior Java developers and also teaches you tools and process to deal with an error like java.lang.OutOfMemoryError. In this article, we will explore what is java.lang.OutOfMemoryError; Why OutOfMemoryError comes in Java application, different type of OutOfMemoryError and How to fix OutOfMemoryError in Java. This article is purely meant to provide basic knowledge of java.lang.OutMemoryError and won't discuss profiling in detail. For profiling read the books I have mentioned before. What is java.lang.OutOfMemoryError in Java OutOfMemoryError in Java is a subclass of java.lang.VirtualMachineError and JVM throws java.lang.OutOfMemoryError when it ran out of memory in the heap. OutOfMemoryError in Java can come anytime in heap mostly while you try to create
