Re: Why CLASSPATH behave so strange?

I tried this on V4R3 system - it works exactly as I described in my
previous note.
When in shell session, enter   echo $CLASSPATH   to check what is the value
of CLASSPATH variable.
Make sure that you use correct case - Java and everything originating from
UNIX are case sensitive.
Another thing - just in case - did you compile your Java program ?
You first create Hello.java with plain text Java program, then call  javac
Hello.java  to generate Hello.class and then run the program by  java Hello
. (I mention this because I made exactly this mistake at my first shot at
Java.)

Still,

Still, I have problems with understanding this CLASSPATH. You said '.' is a
default for CLASSPATH. But it says "UNABLE TO FIND CLASS Hello", if I do
not
create CLASSPATH with the value '.'

Furthermore, if this CLASSPATH is not created, then no matter what I do, I
get
"UNABLE TO FIND CLASS Hello". And here are my experiments:

I close the session and logon again, because I cannot otherwise delete this
CLASSPATH var - the WRKENVVAR offers you the capabilities only to create or
change, NOT TO DELETE, an environmental variable. (Why???)
OK, I logon and, when I do WRKENVVAR, I do not find this CLASSPATH. Then I
do
one of
1. CD '/TEMP' (It is in /temp that I have the Hello.class), qsh cmd('java
Hello')
2. STRQSH session, do CD '/TEMP', then java Hello
3. STRQSH, do /TEMP/Hello
All of these bring to the same  "UNABLE TO FIND CLASS..."  Especially
strange
is the case 3. Why it does not find, even when you indicate the full path!?

There was an answer  to my message from somebody else from IBM, but I only
opened the message, it was marked as read by my AOL and was not downloaded
- I
did not manage to read it. Could you please forward that message too, if
you
happen to answer this message. Thank you very much!

<< This is because STRQSH starts its own job and does not inherit current
 directory setting from your original job. You may prove it by issuing pwd
 command from a prompt after STRQSH.
 You may run Java program by calling STRQSH CMD('java Hello'). In this case
 current directory WILL be inherited.

 BTW, you do not need to bother adding '.' to CLASSPATH. It's there by
 default.

 Environment variables are job attributes and are lost, when job ends.
