Can't run java or javac from dos prompt

Question

I just installed j2sdk1.4.1 on win98SE. I have a problem where I can't seem to be able to compile or run an application from the dos prompt. I can do both in Visualage for Java or in JGrasp but not at the DOS Prompt. I have set the PATH statement to PATH=c:\j2dsk1.4.1\bin and the classpath=c:\j2sdk1.4.1\lib. The following is a typical error message:
javac RunApplet.java
RunApplet.java:8: cannot resolve symbol
symbol : class MyApplet
location: class RunApplet
MyApplet myApplet = new MyApplet():
RunApplet..java:8: cannot resolve symbol
symbol : class MyApplet
location: class RunApplet
MyApplet myApplet = new MyApplet()
2 errors
java RunApplet.class
Exception in thread "main" java.lang.NoClassDefFoundError: RunApplet/class
It seems like the system can't locate the class files?
Also is there away to use more than the standard 8.3 charecter set in the DOS prompt window?
TIA

Answer 1

javac RunApplet.java
RunApplet.java:8: cannot resolve symbol
symbol : class MyApplet
location: class RunApplet
MyApplet myApplet = new MyApplet():
RunApplet..java:8: cannot resolve symbol
symbol : class MyApplet
location: class RunApplet
MyApplet myApplet = new MyApplet()
2 errorsMost likely a Classpath problem. I suggest changing your classpath to:
classpath=.;c:\j2sdk1.4.1\lib
java RunApplet.class
Exception in thread "main"
java.lang.NoClassDefFoundError: RunApplet/class2 problems. As ChuckBing says, the command needs to be "java RunApplet" with no .class. The argument to the java command is the class name, not a file name. The second problem - if you do not have a successful compilation, there won't be any .class file to run.
