This should be fixed in CVS.  Richard had that problem.

Not sure about this.  Jump into the code and see what the problem is.  
Am sure it will be a java 1.5 on linux problem or someone would have 
already posted the problem.

Yes but then again being a programmer yourself that frustration level 
can be reduced by figuring out the problem and making the change to fix 
it :-P

Yeah had thought about changing it to use IBM's scripting package so 
other languages could be incorporated but that meant having to put 
another package constraint to run.  Never moved further than that 
afterwards.

Which again begs the question of why you are frustrated with problems.

Looking at the code base should help with that.

Well actually there really is not any 1.3 being used anymore unless a 
1.3 JVM is used.  Between Christian, Wim and myself using the interfaces 
it is dynamically loaded.  In the code you should be able to find all 
references to them and remove the code from there.  There are I think 5 
touchpoints for this.  Unfortunatel on the first two releases of 1.4 
some of the newer stuff does not work correctly so had to bandage that 
the best way I could.

As far as anything else being 1.3 the hardest most intense part would be 
using the NIO but after I did the test case by changing the code I got 
no increase whatsoever so to me it was not worth the effort of changing 
this all out.  Wim and I discussed this at one time through the list.  I 
might still have the code laying around if anybody wants to have a go at it.

I would love to see the browser version get off it's feet.  What needs 
to be done here besides the HTML parsing part Pete?  I do not remember 
where we left off.  The last thing I remember is the change I made so 
that you could use encrypted  parameters to pass user and password.  Was 
that used in your version?  You had gotten swamped with work so could 
not test it at that time.

This was answered in the other post I made.  Although Patrick, me not 
being around does not mean anybody could not update CVS with changes and 
bug fixes.

I think I remember Christian made a change a while back which was the last.

:-) 

Not exactly sure if the project lacks "leadership" per se but more hands 
digging in the code and updating CVS with bug fixes.

Not a lot of java skills needed to fix the problems you reported so now 
all that is left to do is dig in.  The keymapping problem could probably 
be fixed in 30 minutes.  Let me know and I can tell you where to look.

I will send you some code fixes that other people have sent my way so 
you can put them in and coordinate the changes with the rest of the people.

I hope the project gets going again and am more than happy with the 
suggestions.  Any questions please let me know and I will do my best to 
answer them with the limited resources on my end.
