Error "Class sampleproject.remote.DvdDatabaseImpl not found "

[Rupi Kaur]

Hi

I am trying to run the Denny's Dvd project.

I unzipped the java files into the directory : c:\dvd . I am able to compile the projects db, direct, gui, remote, sockets.

But - when i do 'rmic sampleproject.remote.DvdDatabaseImpl ' I get the following error:

"Class sampleproject.remote.DvdDatabaseImpl not found"

My compiled class lies here : C:\dvd\src\sampleproject\DvdDatabaseImpl

and my project directory structure is :

C:\dvd\src\sampleproject\db
C:\dvd\src\sampleproject\direct
C:\dvd\src\sampleproject\gui
C:\dvd\src\sampleproject\remote
C:\dvd\src\sampleproject\sockets


Can someone please suggest where am I doing something wrong.

Thanks.

Hi Rupi, this amazing post here should help you

[Roel De Nijs]

Maybe you should set your classpath correctly? I would guess rmic -cp c:\dvd\src sampleproject.remote.DvdDatabaseImpl will do the job.

[Rupi Kaur]

Wow, what a prompt reply !!!

Thanks Roel and Sean - that 'amazing post' really helped and I can now run the dvd project.

However, I skipped the rmic step (as suggested in the book that if we are using >= version java5) and it went through fine.

For "rmic -cp c:\dvd\src sampleproject.remote.DvdDatabaseImpl" it said '-cp is an invalid option or argument' .

Thanks much,
Rupi

Use -classpath instead of -cp

[Rupi Kaur]

it still didnt work for me, says that impl class not found. Looks like ihave messed up the classpath and path settings. will figure them out first. thanks !!

Did you use the list of commands in the post I linked to previously in the order listed. Did the rmic command specified not work?

[Rupi Kaur]

I have verified the classpath settings also.they look good.
Yes i ran the commands in the order specified in that link. No, the rmic command specified did not work.

Can you double check that you ran every single command listed and in the order listed? I double checked myself and the commands work for me. If they still don't work, then post up the commands and outputs as I have done below.

Here is my set up before I ran the commands:
F:\06-TEMP\JAVARANCH>set path Path=F:\15-JAVA_CERT\OCMJD\TOOLS\java\jdk1.6.0_22\bin; F:\06-TEMP\JAVARANCH>set classpath CLASSPATH=; F:\06-TEMP\JAVARANCH>javac -version javac 1.6.0_22 F:\06-TEMP\JAVARANCH>tree F:. └───src └───sampleproject ├───db ├───direct ├───gui ├───remote └───sockets
Here are the commands I ran, as listed on the thread, and as you can see they all ran successfully:

F:\06-TEMP\JAVARANCH>mkdir classes

F:\06-TEMP\JAVARANCH>cd src

F:\06-TEMP\JAVARANCH\src>javac -cp ..\classes\ -d ..\classes sampleproject\db\*.java

F:\06-TEMP\JAVARANCH\src>javac -cp ..\classes\ -d ..\classes sampleproject\remote\*.java

F:\06-TEMP\JAVARANCH\src>javac -cp ..\classes\ -d ..\classes sampleproject\sockets\*.java

F:\06-TEMP\JAVARANCH\src>javac -cp ..\classes\ -d ..\classes sampleproject\direct\*.java

F:\06-TEMP\JAVARANCH\src>javac -cp ..\classes\ -d ..\classes sampleproject\gui\*.java

F:\06-TEMP\JAVARANCH\src>cd ..\classes

F:\06-TEMP\JAVARANCH\classes>rmic sampleproject.remote.DvdDatabaseImpl


As you will see from the result below the stub class does get created:

F:\06-TEMP\JAVARANCH\classes>cd sampleproject\remote

F:\06-TEMP\JAVARANCH\classes\sampleproject\remote>dir

Hi Sean

Attached is the output I got. Same again.

This time I replicated the way you said. Please see where I am doing wrong.

Thanks.

[Sean Keane]

Your problem is with your classpath. If you don't set the classpath then the directory that you execute the command from will be searched for your file. If you do set the classpath the directory you execute the command from will not be searched, instead the classpath specified will be searched.

[Rupi Kaur]

It works now - without setting the classpath.

Thanks much.

[Sean Keane]

Super! Glad you got it working. Maybe update the thread with the problem in your set-up and the solution in case someone else stumbles upon this problem in the future, it may be of help to them?

[Rupi Kaur]

Hi all, the summary of my problem with solution is:

I was trying to run the steps to execute the application 'Denny's DVDs'.

While running the command ''rmic sampleproject.remote.DvdDatabaseImpl", I was getting the Error "Class sampleproject.remote.DvdDatabaseImpl not found ".

DvdDatabaseImpl.class was existing as required. But, the problem was that the Classpath was set and " If you do set the classpath the directory you execute the command from will not be searched, instead the classpath specified will be searched.If you don't set the classpath then the directory that you execute the command from will be searched for your file. "

So I remove the classpath setting and ran the command again. It worked !

Thanks to Sean for providing the solution.
