I have mysqlconnector 5.0.7 jar file and i have placed it in program files folder.

The following is the execution of my codings.


c:\program~1\ja va\jdk1.6.0_01\ bin>javac -classpath ";.\program files\mysql-connector-java-5.6.0_01" mysqlconnect

c:\progra~1\jav a\jdk1.6.0_01\b in>java -classpath ";.\program files\mysql-connector-java-5.6.0_01" mysqlconnect

Exception in thread "main" java.lang.nocla ssdeffound error: mysqlconnect


The above error occurs only during running the program and not in compilation time.

How to rectify the error and run the program successfully?

Please help me...

Java is case sensitive, even under Windows, so be careful to write MySQLConnect, or whatever is the exact class name.

The same error occurs even when i give the class name in case sensitive manner also during execution.

Compilation is Successful but not running.

What to do?

Please give me the solution

Are you including the current directory (".") in your list for classpath?

Hello all; I'm trying to debug an issue with a java script called, SelectSockets. It appears to be a fairly common one found on the web. I downloaded the SGI Java v1.4.1 installation from SGI's webpage and installed it using SGI's swmgr application. The installation was very straight forward and there were no errors when I installed the package. Then I ran /usr/java2/bin/javac SelectSockets.java to make the SelectSockets.class file.

For most users, this new feature is actually very convenient. If you want to control the update process,...
