If using OpenJDK or Sun JDK 1.6 or later, usingjstackis an option. This is useful when redirecting standard out to a file is problematic for some reason (e.g. it is not desirable to restart the JVM just to redirect standard out). Execute the following, passing in the Java process ID:...
main: It is the method name. This is the entry point method from which the JVM can run your program. (String[] args): Used for command line arguments that are passed as strings. We will cover that in a separate post. System.out.println("This is my first program in java"); ...
# InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and# row data. The bigger you set this the less disk I/O is needed to# access data in tables. On a dedicated database server you may set this# parameter up to 80% of the machine physical memory size. Do not set...
How do I setup a JUnit test? You must create a separate .java file to setup the JUnit test. It should be in the same project that will test one of your existing classes. Right-click the class you want to test in the Package Explorer area on the left side of the Eclipse window. Cl...

Note It is assumed that you are familiar with the security constraint concept in servlet programming, including principals, roles, realms, login configuration, etc. If you do not understand them, read my ownJavafor the Web with Senlets, JSP, and EJB or any other decent servlet programming bo...
I have a daemon thread responsible for some I/O, the main thread finishes and returns, and the JVM decides to terminate my daemon thread. How does it do so? Interrupt? Finalize? How can I code my daemon thread so that it reacts gracefully when terminated? java mult...
