Re: Problems while reading an InputStream

Diego,

some MIDP implementations seem to have strange problems with

- recognizing the end of the input stream
- supporting utf8

perhaps you can try to encapsulate the InputStream in a BoundInputStream 
available at kobjects.org to make sure that no more than 
"content-length" bytes are read, but that will help only if a valid 
"content-length" header is transmitted by the server.

Best,
Stefan
