Re: Read file in the jar file?

That's OK.
Thank you for your help.

Another problem.

If I have a file structure
/core/ (here is application)
/core/doc ( here is the doc )
/core/doc/filecollection1/
/core/doc/filecollection1/subcollection1/
/core/doc/filecollection1/subcollection2/
/core/doc/filecollection2/
/core/doc/filecollection2/subcollection1/
/core/doc/filecollection2/subcollection2/

I compress the file and doc in the jar file.I want to access to every dir or
file recursively.

How to write my code?

PS:
I have written the code
....

File codebase = new File("/core/doc");
....
public String read_file_recursive( File file)
{
String ret;
if( codebase.isDirectory())
{
File[] filelist = codebase.listFiles();
for( int i = 0 ; i < filelist;i++ )
{
ret += read_file_recursive(filelist[i]);
}
}
else
{
// read file content ...
}
return ret;
}
....
But it doesn't work under the jar file.
