Hi.
This has nothing specific to Tomcat, it's just a problem I'm having as a
non-java expert in modifying an exiting webapp.
I hope someone on this list can answer quickly, or send me to the
appropriate place to find out. I have tried to find, but get somewhat
lost in the Java docs.
Problem :
an existing webapp reads from a socket connected to an external program.
The input stream is created as follows :
fromApp = socket.getInputStream();
The read is as follows :
StringBuffer buf = new StringBuffer(2000);
int ic;
while((ic = fromApp.read()) != 26 && ic != -1) // hex 1A (SUB)
buf.append((char)ic);
This is wrong, because it assumes that the input stream is always in an
8-bit default platform encoding, which it isn't.
How do I do this correctly, assuming that I do know that the incoming
stream is an 8-bit stream (like iso-8859-x), and I do know which 8-bit
encoding is being used (such as iso-8859-1 or iso-8859-2) ?
I cannot change the InputStream into something else, because there are a
zillion other places where this webapp tests on the read byte's value,
numerically.
I mean, to append correctly to "buf" what was read in the "int", knowing
that the proper encoding (charset) of "fromApp" is "X", how do I write
this ?
Thanks.
