Hello Dave, I thought about this overnight because I did not want what I say next to sound really patronising; anyway, here goes.
When you deploy the application you are working on, you will not deploy the .java file as it contains the source code you have created. Rather, you will deploy the .class file which contains the pre-compiled bytecode that the JVM will load, compile into native code and then run. Also, you will need to make sure that the machine upon which your application runs has access to the POI archives because the JVM needs to locate, load and run one or more of the classes it contains. I am sure you knew all of this and that is why I worried about it sounding patronising, but when you said in you last message that you interest was in a single .java file that you planned to implement on another machine, I worried a bit. Now, one of the easiest ways to achieve all of this is to use the contents of the dist sub-folder that Netbeans will create for you. It will create an archive that contains your class and ensure that the other archives your application needs are copied into it's lib sub-folder. All you then need to do is copy this over to the host machone and your application ought to run. Of course, you do not have to use this structure and there are good reasons not to do so; you can copy the POI archive into a different folder even on another machine as long as you ensure that it is accessible to your application at runtime. It is quite likely that you will need to set the -classpath environment variable to ensure that the JVM can locate the resources it requires at runtime. I work almost exclusivly on Windows and use .bat files (batch files) extensively to run applications as they allow me to create instructions such as this; "C:\Program Files\Java\jre1.6.0_07\bin\java" -classpath ".;..;" -jar "C:\Work Area\Programming\Java\Development\Netbeans\Neat\File Processor\dist\File_Processor.jar" and set the -classpath the application uses when it is executed. Sadly, I do not know if such a mechanism exists on Linux but suspect that it does.
