Running the java program

[Sireesha ikkurthi]

Iam trying to run the java program which i have written in notepad, it is compiling properly, but it is not running when i gave the command as

java filename

The error message it is showing as

Exception in thread "main"java.lang.NoClassDefFoundError: customer

customer is the file name

for any other java program also it is showing like the same error.

kindly help me out to run my java programs, as what might be the problem.

Take a look at this from Sun's Tutorial. The section "Runtime Problems" may help you solve the problem.

Hi.
I hope you are doing okay.

Such errors are given, if the class is a driver class or it
doesnt have a main method. Does your class contains the main
method or when you are invoking the classes from the Driver program
are you doing the instantiations properly?

I think it's more likely that this is a classpath issue. The Tutorial section Barry linked to probably explains that.

[Srikanth Nakka]

Take this example

if your file location is
c:\fol1\filename.java and use classpath as
----> java -classpath "c:\fol1" filename

I think this will solve your problem

acutally the problem is on the classpath that is the JVM cant able to find the class before compling any java program you have to set classpath for the JVM in dos console

the command is c:>set classpath=%classpath%;.;

after giving this and type javac filename.java and run the java command
