problem running compiled class file

[SnakeDoc]

Hello All!

I'm learning java still, so please bear with me if this turns out to be something obvious (cuz its not to me! ;-P ) I was hoping someone may be able to shed some light on this error i'm getting...

I'm working with some source files and compiled a .java file into a .class file and used the -cp to specify my working directory as there are a lot of other .java files that are imported. I successfully compiled into .class with no errors.

When i attempt to go and run the file from the command line, I get one of two errors depending on if i use the -cp switch again or not.

command:

java GetServiceStatusSample

| results in:

Did you compile the source code with no errors before trying to execute it with the java command? Where is the .class file?

The code you posted is in a package. You must set the classpath to the folder that contains the folder that is the first name in the package path: com

The classpath + the package path should point to the folder with the class file. No overlapping of the paths.

The full package/class name should be used with the java command:
java com.amazonservices.mws.sellers.samples.GetServiceS tatusSample

[SnakeDoc]

1) yes it compiled with no errors using the javac -cp command and the .class file is located at \com\amazonservices\mws\sellers\samples\

the exact command i used to compile:

C:\Documents and Settings\jason.s\Desktop\AMZ_Auto\
new_workspace\Complete\com\amazonservices\mws\sellers\samples>javac -cp "C:\Documents and Settings\
jason.s\Desktop\AMZ_Auto\new_workspace\Complete" GetServiceStatusSample.java

no errors at time of compilation. the resulting .class file is located in the same directory that i ran my command from... so:

C:\Documents and Settings\jason.s\Desktop\AMZ_Auto\new_workspace\Complete\com\amazonservices\mws\sellers\samples\

2) i'm not sure i'm following you with your next bit.

when i attempted to run the file using:

C:\Documents and Settings\jason.s\Desktop\AMZ_Auto\new_workspace\Complete\com\amazonservices\mws\
sellers\samples>java -classpath "C:\Documents and Settings\
jason.s\Desktop\AMZ_Auto\new_workspace\Complete" GetServiceStatusSample

my working directory looks like this:

as a side note, I depacked all the .jar files into their respective folders (com or org or javax or 1.0) --- all .jars had the same base

3) I tried your suggestion of running the class file like:

C:\Documents and Settings\jason.s\Desktop\AMZ_Auto\
new_workspace\Complete>java com.amazonservices.mws.sellers.samples.GetServiceStatusSample

and got another error:

That looks like you are now executing your java class. Now you will have to find some one that knows how to configure and execute the program. It is using third party classes.
Your problems are way beyond standard java problems.

Good luck.

[SnakeDoc]

does this mean in your opinion that the Java file is being executed (run) but that there may be a problem wtih one of the 3rd party packages? if so than this is progress for me, if not then i'm lost as ever.

just a side note to anyone out there who cares: the Amazon MWS API is horrendously documented and extremely difficult to make sense of... they basically say, unpack the zip file, configure ur account credentials, then run the sample files. -- as if it works out of the box... I may be new to java, but this is crazy lol. lots of easy to find threads on other forums with people venting about the MWS api... people with a lot more java experience than myself lol. **rant done** ;-P

The error message you got was from the program as it was executing. I have No idea what the program is trying to do or what its problem is.
