Hi
I've got a problem that's outside my experience and need advice.
I've got a MIDlet which logs data to a server over HTTP and parses what
comes back. The method concerned is:
/**
* attempt to parse zones from the input stream
*
* @param in the input stream, presumed to be generated by
*
uk.co.weft.fisherman.fieldkithandler.HandleInspectorBadge
*
* @see uk.co.weft.fisherman.fieldkithandler.HandleInspectorBadge
*/
public void parseResult( InputStream in )
{
StringBuffer buffy = new StringBuffer( );
boolean done = false;
while ( !done )
{
int c = -1;
try
{
c = in.read( );
}
catch ( IOException e1 )
{
/* ignore. c will pass through as -1, which
will set done
* to true and tidy up the last line read if
possible */
}
switch ( c )
{
case -1:
case 0:
done = true;
/* note: deliberately no break */
case '\n':
try
{
if ( buffy.toString( ).trim(
).length( ) > 0 )
{
new Zone(
buffy.toString( ) );
}
}
catch ( Exception e )
{
fieldkit.showMessage(
AbstractFieldKit.MESSAGETYPEERROR,
e.getClass( ).getName(
) +
" while reading zone" );
}
buffy = new StringBuffer( );
break;
default:
buffy.append( (char) c );
break;
}
}
}
The while loop procedes normally until the end of the first line of
input. However, when it gets to the line
new Zone(
buffy.toString( ) );
the emulator goes down hard with the following error message logged to
the Eclipse console:

It goes down identically hard whether I use Sun Java 1.4.2 or IBM Java
1.5 To run Eclipse.
The only thing I've found about this on the web is this post on the sun
Java forum where the guy is also developing on Linux using EclipseME
1.5.5:
http://forum.java.sun.com/thread.jspa?threadID=761056&messageID=4345708
and this thread where the guy says he's using Eclipse but does not say
what version of Eclipse ME he's using (although I assume he is because
he talks about preverifying his MIDlet in Eclipse).
Is this an Eclipse ME problem and if so is there a workaround?
Cheers
Simon
