Directory, File, Jar input problem

[Ronnie Coh]

I've written a program that reads files from vaious locations on my drive to populate JComboboxes. It works file when I run the program through an IDE, but when I Jar the Classes it will not work.

Here is an example:

cboCrop = new JComboBox();
String line = null;
BufferedReader br =
new BufferedReader(
new BufferedReader(new FileReader("C:\\Test\\Data\\Jclimate.txt"));
while ((line = br.readLine()) != null)
{
cboCrop.addItem(line.substring(3, 3 +12));
}


Any suggestions will be appreciated. Thanks...Ronnie

'will not work' isn't precise enough.

Is there a general 'catch (Exception e)' clause, which is silent as the grave of the dead programmer ({})?

The problem is that it will not find the file when I run the program in my JAR.

Thanks.

So you are getting a ClassNotFound exception?
In order to find a class file within a jar, either the classpath has to contain the jar file:

 
java -cp some.jar MyClassName

Or you create an executable jar and run it with the -jar flag:

  
java -jar someExecutable.jar

No, ClassNotFond Exceptions. The program just hungup. I managed to get it to work by putting the Data and Text files outside the Jar in the same foldre as the jar.

Not the Jar will not finded the two Jars that war included in the jar. I uded a Manifest file file:

Main-Class: folder.program
Class-Path: folder.jarone.jar folder.jartwo.jar

But it will not find the two jars. Any ideas? Thanks
