java.lang.NoClassDefFoundError [message #243463]

When I make Java programs within plug-in development preference , they run
ok. But when I write a program under Java preference platform I get
java.lang.NoClassDefFoundError.Could this be for some files needed to be
included in build path? Though checking for Java, outside Eclipse shows
that it is included in the path.What are the reasons for this error?

I have Eclipse SDK 3.2 and Jdk 1.6 under OS Linux

What are the classes that are not being found?

What have you tried so far to explore or fix the problem?

My java program is (a very simple one)as follows:
package cnvpth;
public class ConvertPath {
public static void main(int argc,char argv[]){
char ch;
int i,k=0;
String FlPath="sting to to form sub strings";
StringBuffer sb = new StringBuffer(FlPath);
int PathSz = FlPath.length();
int ActualSz = PathSz - 6;
sb.setLength(ActualSz);

for(i=6;i<(PathSz + 1); i++)
.
.}
The "main" thread cannot be located.That is why I thought it to be a "path
inclusion problem".Do I need to import something?

In Java, the main signature is:
public static void main(String[] argv)

otherwise your class is not considered to be an executable class.
