Let us first explore and understand the structure of this simulation project. I assume that you have already set up the cloudsim using Ecplise if not you may follow my previous article on Cloudsim Setup using Eclipse.
The readme.txt file contains the necessary information about this project, like how to install and run the cloudsim, what is the basic directory structure, if you are not using any IDE then how to build the project source code.

The VmScheduler is an abstract class that defines and implements the policy used to share processing power among virtual machines running on a specified host. The hierarchy of the cloudsim virtual machine scheduler classes is as:
This is where the processing element list is passed as a parameter to the VmSchedulerTimeShared() class call and during the simulation, the cloudsim will simulate the timeshare behavior for the virtual machines. Also, in case you want to test other VmScheduler you may replace it with VmSchedulerTimeShared() call with appropriate parameters, this includes your own designed custom virtual machine scheduler.
Great post Javin on this common error. I'm glad to see what you spent some time understand this problem at a deeper level. Your Blog has quite a lot of Java tutorials and problem patterns; great sharing for the Java community.I would like to add that in my Java EE experience, the typical root cause of NoClassDefFoundError that I see from my clients Java EE apps are either classpath / libraries conflict or code failure of a static block. For people interested, I also have a post from my Blog on the NoClassDefFoundError problem patterns from a Java EE perspective along with a sample Java program simulation.Thanks again.P-H
Hello , I have used a tutorial from the net using which I have compiled and made an EJB jar and deployed it in standalone folder of jboss as 7.7.1 server.I have added a client user name using add user.bat I also have a jndi.properties file.My client class makes a lookup and when I try to run it, I get the following error : Exception in thread "main" java.lang.NoClassDefFoundError: test/ClientCaused by: java.lang.ClassNotFoundException: test.Client The command which shows this error is : java -cp JBOSS_HOME/bin/client/jboss-client.jar:. test.Client ejb:/client-ejb//ClientBean!test.ClientIF Can youguide me with what the issue is?Thanks a lot.Appreciate any help.

I'm working with MyEclipseWorkbench8.5 when I'm working with simple class files it is working fine but while working with the JDBC it is giving this following exceptionException: in thread "main" java.lang.NoClassDefFoundError: java/sql/SQLClientInfoException at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:164) at com.mysql.jdbc.ConnectionImpl.(ConnectionImpl.java:213) at com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:282) at java.sql.DriverManager.getConnection(DriverManager.java:548) at java.sql.DriverManager.getConnection(DriverManager.java:180) at com.Mytest.ConnectionPool.getConnection(ConnectionPool.java:17) at com.Mytest.DBTest.main(DBTest.java:15)I have developed my project like this:1. I have given perfect database properties. 2. I have added corresponding jar file in classpath(with the above tutorial I have traced com.mysql.jdbc.Driver class also in the jar and I have attached same jar file to my project classpath)3. I have tested this code in some other system and it is working fine.Kindly help me to rectify this problem...Thanks in advance
