I keep getting this error. The app is looking for a class and in fact so am I
where should this class be? I can't find it in the:
db-derby-10.6.2.1-bin and check sup of the dl said it was unaltered?
Thanks

I'm not familiar specifically with Apache Derby, but usually when you download a JDBC driver, there's a jar file which you need to put in your classpath. Did the file you downloaded include a jar file? Did you put the jar file in your classpath?

I am in the process of doing that again.
My documentation says to user set. Isn't that temporary?
how would I remove the setting below if it were wrong?

Windows: C:\> set DERBY_INSTALL=C:\Apache\db-derby-10.6.2.1-bin

also I am using the Windows Enviornment variables (rt click my computer) and I'd like to know if I use the variables %DERBY_INSTALL% etc to build paths like I did in the cmd line?

so far I have just added ... ;C:\db-derby-10.6.2.1-bin\db-derby-10.6.2.1-bin\bin
to the end of the PATH VARIABLE
ex:

Windows: C:\> set DERBY_INSTALL=C:\Apache\db-derby-10.6.2.1-bin
then
Windows: C:\> set CLASSPATH=%DERBY_INSTALL%\lib\derby.jar;

I am just having trouble setting it up.

What happened to the previous thread which you created for the same issue? I thought you had managed to sort it out?

I am working with the class path still as before as you can see the results are the same;
I also have the app built in eclipse with the exact same error. I stopped when I didn't find
the magic button to create the one jar.

I just ran the stand-alone one jar program and have results that are unclear. I will
post them to view . I was just going to try to find a forum that handles the on jar question. That is if creating one jar is not covered here.


thanks

I have my project (app) and I was trying to use the one jar

program.
Has any one ever used one jar to create a .jar?

I ran the program:

Shouldn't derby know what it driver is?

It looks like it must be a classpath problem, because you seem to have the correct string for finding the class within the jar file in your code.

Are you running your app from the command line or from inside an IDE?

It looks like you are trying to set up your environment variables using a batch file. Have you tried to use the system environment variables setting?

There are several problems to come such errors. sometime java software is not propositional with system. mostly 80% problems faced form this. you have to reinstalled latest software of java. if you not set the right path of java then also error is occured. and sometimes your class declaration is wrong which is silly mistake. so do analysis on this.

I can try to re-install the jdk but this is the Enviornment. My app is run from Netbeans IDE.

Do not reply to technical articles if yo have no clue. Your signature spamming is not welcome, you do it again and we will take action.

Thanks lol I thought I did something wrong again.

Here is what I got if I could get some feed back that would be great! thanks.

Can anyone help me load this derby driver I have tried to set

everything.
on my computer I have %Path% and I thought that is where the

classpath for programs was.
not sure any more because the examples use %PATH% and

%CLASSPATH% any way this is what I have.

On this installation I would like to use the tools derby has. ij

in particular or any other tool recomended.

Hmmm. At the top of your last post, when you do sysinfo, it shows that
C:\db-derby-10.6.2.1-bin/lib/derby.jar is on the classpath (although the slashes look a bit messed up). But near the end of your post where you "ECHO %CLASSPATH%", it only shows C:\db-derby-10.6.2.1-bin\lib\derbytools.jar and not C:\db-derby-10.6.2.1-bin\lib\derby.jar. I think you need the latter on your classpath (not your PATH).

Also, I'm not familiar enough with NetBeans, but in eclipse you set up the jar files you want in your project settings, and it doesn't matter what's on the classpath outside of the IDE. So you might need to check the NetBeans settings.

Finally, I don't know why this thread was marked solved when clearly it isn't.

Edited 6 Years Ago by kramerd: n/a

I changed the position of %CLASSPATH% in the %Path% at post time because while editing
I discovered ';;' and found and entry with out a ';' I don't think it matters but I will
re-do. right now.

here is the actual Enviorment variable:

You should not be adding your CLASSPATH to your PATH. These are two different things. The PATH is where Windows finds programs to execute. The CLASSPATH is where Java finds classes, both at compile time and at runtime.

At the top of this most recent post, you say here is the environment variable. I'm guessing that is the PATH. You should take %CLASSPATH% off the end. It doesn't belong there.

The second part of this most recent post again shows that the CLASSPATH only contains derbytools.jar and doesn't contain derby.jar. This is the problem that needs to be fixed.

I took %CLASSPATH% off the end of path and added %DERBY_INSTALL%\lib\derby.jar to the %CLASSPATH%

It still goes to properties and gets org.apache.derby.jdbc.EmbeddedDriver entry and
the sys can not find that..
I will have time to start it over again tonight. The first time I set it up it was easy.
I thought I added something to the project at that time. Like a library or something. Is this possible?
Thank you for your time.

Yes, as I said before, you probably need to add the jar file to your project inside of NetBeans.

That did it . I learned a great deal about Environment variables and Command syntax. The App runs again. Thanks for the help.
