when i set a classpath variable a very easy program can't find it'sown class

[Selmar]

Hi,

I have the following, i think very easy to solve, problem.

I try to run a very simple program (look below, it's just a test program).

It compiles very well with “javac TestClass.java”
But when i want to run it i get the following error
java TestClass
java.lang.ClassNotFoundException: TestClass
at kaffe.lang.AppClassLoader.findClass (AppClassLoader.java:296)
at java.lang.ClassLoader.loadClass (ClassLoader.java:142)

I only get this message with in my /etc/profile the following line:

export
CLASSPATH=/usr/java/j2sdk1.4.2_04/jre/lib/ext/biojava-1.30-jdk14.jar:/usr/java/j2sdk1.4.2_04/jre/lib/ext/bytecode-0.91.jar:/usr/java/j2sdk1.4.2_04/jre/lib/ext/jakarta-regexp.jar:/usr/java/j2sdk1.4.2_04/jre/lib/ext/xerces.jar:/usr/bio-java/demos:/usr/MySQL_java_driver/mm.mysql-2.0.14

without this line it works right. But i need this line for other things.
Does anyone knows the solution for this problem?

Tanks in advance,

Selmar.

The file i compile and try to run:
public class TestClass
{

public static void main (String[] args)
{
int oranges=5;
int apples=10;
int fruit=0;
fruit=oranges+apples;

System.out.println("A totallly fruity program");
System.out.println(fruit);
}

}

environment variable with that line

java.lang.ClassNotFoundException: TestClass

I only get this message with in my /etc/profile the following line:

export
CLASSPATH=/usr/java/j2sdk1.4.2_04/jre/lib/ext/biojava-1.30-jdk14.jar:/usr/java/j2sdk1.4.2_04/jre/lib/ext/bytecode-0.91.jar:/usr/java/j2sdk1.4.2_04/jre/lib/ext/jakarta-regexp.jar:/usr/java/j2sdk1.4.2_04/jre/lib/ext/xerces.jar:/usr/bio-java/demos:/usr/MySQL_java_driver/mm.mysql-2.0.14

The classpath is missing an entry for the current directory .

without this line it works right. But i need this line for other things.

You shouldn't need it. In fact, any use of the CLASSPATH environemnt variable
is discouraged. Instead, the -cp command line switch of the JVM should
be used so that each program gets the classpath it needs and only that.

Thank you, this works!!
