Read a txt file from MIDlet

Question

dear sir,
I am working on a midlet which should read position information (privided by TOMTOM GPS) from a TXT file and send it to a server.
In Toolkit everything works fine, but when I transfered the midlet on a ipaq pocket pc running windows and using IBM j9 jvm I got problems.
I can not read any file which is not in the package of the MIDlet
here is the code:
//read position from textfile
try {
Class c = this.getClass();
InputStream is = c.getResourceAsStream("iamhere.txt");
StringBuffer str = new StringBuffer();
byte b[] = new byte[1];
while ( is.read(b) != -1 ) {
str.append(new String(b));
is.close();
position = str.toString();
catch (Exception e) {
e.printStackTrace();
position = new String("Sorry: I can not read position of your friend!");
can it be that this operation is generally not allowed or that the path is not correct (i tryed also file:///java/iamhere.txt)
thanks for any help

hi,
this works fo me:
download ibm websphere trail from IBM website.
install websphere andwebsphere everyplace on the pocket pc
in the websphere program there is a update tool
launch it and download and install fileconn.dll pimdll.dll
(I do not remember how it is called but something like jsr 75 or fileconnector or fc)

and in the JAD:
MIDlet-Permissions:

hope this helps.
