Not 10, but 6 things about jMeter

I list down some "good to know" things about jMeter. Hope it helps you while considering the jMeter scripts design, development and execution.
  1.  Its open source Java tool for functional and load testing.
  2. Can be "extended" to create new sampler, controller etc.
  3. Module Controller - If your scripts are going heavy and you found many copy-paste steps; in that case just create a module of those steps. Module is like a function in programming.
  4. Include controller - Some modules are global and can be used in many scripts, in that case just include that JMX into your main JMX, like you include JSP tag.
  5. Parameterized Controller - Third party controller which enable us to pass various runtime parameters to sample. Usually sits on top of module controller. http://code.google.com/p/jmeter-plugins/
  6. jMeter scripts can be executed from ANT, it help in automating the daily execution of scripts. (Can be triggered from nightly build process from your CI server): http://www.programmerplanet.org/pages/projects/jmeter-ant-task.php The same site also got one XSLT for transforming your JTL (jMeter log of sript execution) to HTML report. 
I''ll update this list as I explore jMeter more!

GlassFish V3 admin console taking too much time to load.

If you have installed Glassfish V3 and trying to load admin console, but after signing in, is it taking too much time to get to the main page ? Do you have server.log entry like this: admin console: initSessionAttributes() Cannot refresh Catalog : Connection timed out then its time to tweak some files. Here its how: 1. Update the %GLASSFISH_HOME/glassfish/domains/domain1/domain.xml -Dcom.sun.enterprise.tools.admingui.NO_NETWORK=true This will block up the News item, the registration item, etc 2. Remove update tool jar (Backup and remove this JAR) %GLASSFISH_HOME/glassfish/modules/console-updatecenter-plugin.jar Delete this dir: %GLASSFISH_HOME/glassfish/domains/domain1/osgi-cache %GLASSFISH_HOME/glassfish/domains/domain1/generated Now start the server (bin/asadmin start-domain) and you will see the admin console won't be hang up and take you directly to main page.

Java Generics: Why I get "name clash" exception when I override methods with different "type" parameter ?

import java.util.*; class Parent { void foo(List<String> list) { System.out.println("parent"); } } class Child extends Parent { void foo(List<Integer> list) { System.out.println("child"); } } When you compile this code you will get an error like Parent.java:7: name clash: foo(java.util.List<java.lang.Integer>) in Child and foo(java.util.List<java.lang.String>) in Parent have the same erasure, yet neither overrides the other class Child extends Parent { ^ 1 error This "name clash" error thrown because of "type erasure" thing when "generics" code gets complied. Let’s see how, When we complied any generics code, the compiler removes the type from the code and treat it as a simple pre Java 1.5 code, like, in our case, compiler saw something like this, import java.util.*; class Parent { void foo(List list) { // oops, <String> get erased. System.out.println("parent"); } } class Child extend...
