First J2EE test in Arch and a problem with database adapter SOLVED

I am trying to get my feet wet with J2EE and spotted a nice walkthrough article here - http://www.sitepoint.com/article/java-6 … c-web-apps.

All went fine until the part when I should have got the data from the database at the end of the first part - "java -classpath .;./mysql-connector-java-5.0.5-bin.jar com.sitepoint.ToDoTest" This command ends up displaying weird scrambled output like this:

    -agentlib:<libname>[=<options>]
                  load native agent library <libname>, e.g. -agentlib:hprof
                    see also, -agentlib:jdwp=help and -agentlib:hprof=help
    -agentpath:<pathname>[=<options>]
                  load native agent library by full pathname
    -javaagent:<jarpath>[=<options>]
                  load Java programming language agent, see java.lang.instrument
    -splash:<imagepath>
                  show splash screen with specified image

Not sure how to proceed here - I guess I am missing something.

Re: First J2EE test in Arch and a problem with database adapter SOLVED

"java -classpath .;./mysql-connector-java-5.0.5-bin.jar com.sitepoint.ToDoTest"

I think this is your problem. I *think* that the original application was set up on Windows, which uses semicolons as directory seperators (for the classpath). Linux uses colons.

Linux uses the semicolon as a delimiter between commands, so your command is actually two commands run one after the other.

java -classpath .
./mysql-connector-java-5.0.5-bin.jar com.sitepoint.ToDoTest

What you have with your gobbledegook is the tail end of the java help (because you've tried to run a java application but not given it anything to run.

The second bit is because you have tried to run the mysql-connector-java-5.0.5.bin.jar as a shell script.  It isn't one, which is why you get gobbledegook error messages.

So, try changing the semicolon to a colon smile

Re: First J2EE test in Arch and a problem with database adapter SOLVED

Thanks, I got it to work now! I used this line instead at the classes-dir:
"java -classpath .:../mysql-connector-java-5.0.5-bin.jar com.sitepoint.ToDoTest" and it ran nicely.
