PhoneDirImpl.ja va
PhoneDirInterfa ce.java
PhoneDirServer. java

Hi,
What is the problem you hava is you did not store the file in correct folder.

If all are in the same directory then create one folder "PhoneDirectory " and store the file "PhoneDirImpl.j ava" in it. And compile the file "PhoneDirImpl.j ava" which is stored in that folder. After that compile your main program. You will get the output as you expected. Do the same thing for "PhoneDirInterf ace.java".

And reply what happen...

Thanks and Regards,
Srinivasan r.

Good; now at least javac can find the correct source. The above is simply
a compilation error (missing brackets etc.) Learn how to read compiler error
diagnostic messages.

The compiler expected something more following that right curly brackets
which indicates that your brackets don't match properly.

kind regards,

Jos

[oll3i]

yes you are right that was a bracket (one too many)
i corrected it and now i get

D:\JAVA_P~1\SIM PLE~1\PHONED~1> javac -classpath . PhoneDirImpl.ja va
PhoneDirImpl.ja va:16: cannot find symbol
symbol: class PhoneDirInterfa ce

Did you successfully compile PhoneDirInterfa ce first?

[oll3i]

yes i did .

[oll3i]

why it can not find it?

[r035198x]

why it can not find it?

You have

 import PhoneDirectory.PhoneDirImpl;

But you said they are in the same directory?

[oll3i]

server is in a Simple_RMI directory then
PhoneDirImpl.ja va and PhoneDirInterfa ce.java are in a subfolder of Simple_RMI which i named PhoneDirectory but i have problems now with compiling PhoneDirImpl.ja va

the server compiles .... i dont know what it means " unchecked or unsafe operations"

D:\JAVA_P~1\SIM PLE~1>javac -classpath . PhoneDirServer. java
Note: .\PhoneDirector y\PhoneDirImpl. java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
