Hi, > I would say Tomcat 4.1.x probably would be good for you mainly if you >uses lots of Taglibs, if they actually will work on it. > Btw, I'm still using 4.0.x... how everybody is doing with 4.1.x? I >heard is too much buggy for production right now. We're using 4.1.10-LE and 4.1.12-LE in production. It's been good and stable, except for one bug, but it's an annoying one: something in our HTTP headers trips the 32K buffer size limit, and so we get an ArrayIndexOutOfBounds exception from one of the internal Coyote classes sometimes. The good news is that if you look closely at the test milestone from yesterday, 4.1.13, there's an item addressing the above ;) Buffer size increased to 48K. I downloaded and setup a couple of 4.1.13 test servers yesterday and I'm having our QA team run some tests against them to attempt to duplicate the exception above. So far, so good, no exception. I'd be interested to hear if other people have seen the above exception when using 4.1.x. Yoav Shapira Millennium ChemInformatics
