File structure in a Java project

What should I place the jar library that I have included in my project?
such as rs2xml.jar

Thanks
Jack

External jars need to be on the classpath and not necessarily inside your project structure. In fact, having them on the classpath, lets you share them across projects.

Hi, I am back
First of all,
I have a directory structure

I compile it by netbeans.
When I go to D:\Project\boksspatientproject\build\classes
I typed jar cvfm patient.jar MANIFEST.TXT boksspatientanalysis\*.class
a jar file patient.jar is created. However, I've got a message
Saying it cannot find the main class (Translated)

I believe, yes, it's the classpath problem
What classpath should I set in my case?
I've also learned from the web that there are some software that does this
- packaging all jar libs with the main jar into one jar so that there won't be any dependencies.
Do I have to set classpath as well if I use those software and packaged jar application?
Thanks
Jack

That has got nothing to do with your original question. This error is indicating, that the JVM is unable to find the application entry point

You will have to specify which packaging applications you are referring to. Does it have any documentation? Does it answer your question regarding jars and classpaths?
Usually one also specifies the classpath in the manifest file http://docs.oracle.com/javase/tutorial/deployment/jar/downman.html

Hello Maneesh,
Thanks for your help first.
Okay, the entry point is found. But as the third-party libraries are not included in the jar file created, I've got these

I put the Class-Path: rs2xml.jar.. blah
still got the errors!

I put the Class-Path: rs2xml.jar.. blah

Where is the rs2xml.jar? Is it the same place like your generated jar? Did you read the classpath link I had provided earlier?

Dear Maneesh,
I put it in the same folder as the main jar file.
Thanks
Jack

Can you show us your manifest file?

Here it is. Thanks

From the manifest classpath link I had provided earlier

Warning: The text file must end with a new line or carriage return. The last line will not be parsed properly if it does not end with a new line or carriage return.

Can you confirm your manifest file ends with a new line ?

OK, now, thanks

For the benefit of future uses, can you elaborate on this? Do you mean the manifest was missing the newline, which solved your problem?

Hi,
I forgot that I've deleted the libraries files in the same folder as the main jar. That's it
