HELP TO SEDJ !!!!

[josee411]

HI,
i followed to the letter you instructions in your last message, this 's the result.

C:\>set JAVA_HOME=c:\j2sdk1.4.0_01

C:\>set CLASSPATH=%\jre\lib%

C:\>java -cp
Error: could not open `C:\Program Files\Java\j2re1.4.1_01\lib\i386\jvm.cfg'

C:\>

>>> Error: could not open `C:\Program Files\Java\j2re1.4.1_01\lib\i386\jvm.cfg'

This indicates that you JAVA_HOME does not point to the base directory of you SDK. Are you sure JAVA_HOME is set ? Does the directory exist. Can you see the jvm.cfg file ?

i'm sure having set java on my computer lot of times so as to be sure.
this my classpath: c:\j2sdk1.4.0_04\binand i have files : lib, jre, demo and others come with installation.
i have also class.hello seeing it in file bin
so, more explain:
i did c:\j2sdk1.4.0_01\bin\dir
then i saw class.hello
and
i did:
c:\j2sdk1.4.0_01\bin\java hello
and i have this error.
Exception in thread "main" java.lang.NoClassDefFoundError: hello

 

[sedj]

>>> c:\j2sdk1.4.0_01\bin\java hello

As I said before, this is a CLASSPATH issue.
Do

"java -cp . Hello"

i tried this:

C:\>java -cp.hello
Error: could not open `C:\Program Files\Java\j2re1.4.1_01\lib\i386\jvm.cfg

thanks lot

sorry to disturb you,
this's the last new:

C:\j2sdk1.4.0_01\bin>java -cp.hello
Unrecognized option: -cp.hello
Could not create the Java virtual machine.
i have a question, when you install java from 'installing'
do you add something after installation, i mean some files or Kit.
thanks for replying

>>> Unrecognized option: -cp.hello

Put spaces in between "cp" and "." ::
"java -cp . hello"

>>> i have a question, when you install java >>from 'installing'
>>do you add something after installation, i mean some >>files or Kit.

If you have downloaded the SDK (1.4 or whatever) from the sun site, you don't need any other packages or kits ( for standard stuff).

But you do need to set environment variables like JAVA_HOME, CLASSPATH and PATH.

that's ok, i resolve the problem,
i didn't know java is very sensitive to space, gamma, etc.
i worked on oracle, VB(you have all the porprities you need).
but in java is too difficult if you ignore case or space.
thanks lot.
