Re: Tomcat and Wap

[Simon Mitchell bpc]

I changed these two line to get it to work from my nokia.

*<%@ page contentType="text/vnd.wap.wml"%>*

* String ss1=new String(readbyte).substring(0,charcount);*

Need to print only the charaters read into the buffer.

You will get an error if the file is zero length so you could do a test 
before String ss
E.G.
* if (charcount == -1) charcount=0;
 String ss1=new String(readbyte).substring(0,charcount);
*


You could also do other test on length of the file with

File infile=new File("C:/TextFiles/" + filename + ".txt");
long strLen =  infile.length();

Regards,
Simon
