hi, i developed a web application using java and hosted it in a resin2.0.1 environment.
the web application is doing well and all the modules are perfectly running.
the problem is the resin server displays a can't contact servlet runner at [IP address] occassionally. we resolve this problem by restarting the jsp engine and everything is doing well again.
but the problem is, we can't run our application smoothly. we asked the technical support of our hosting provider and he said that it might be in our code.
pls help. thanks =)

the "cant contact servlet runner at xxxxx" means, plain & simple that the servlet engine has rebooted. There is a know bug in Resin 2.0.1 that invokes a zip Handler. The bug is documented on caucho's site & is supposed to be fixed in the new version. You wouldnt happen to be hosting on CWI would you? I have several sites running there and have the same problem, their CTO knows about the bug & has promised to upgrade asap but their tech support just LOVES to blame the programmer (couldnt ever be them right?
To see if it really is this bug look at your stdout.log file (thats where it shows up on my sites) If it is this bug you will see something like Resin has encountered an error outside of the JVM & then a stack trace a mile long that all leads to this one method....
Also Check out caucho's BBS for explanation of the bugs.

I can tell you right now what they will say.....it's not happening on the other sites, must be a problem with your code. They are a great host but their basic tech support leaves a LOT to be desired. I have communicated with their CTO on several occasions & he really is a great guy who is willing to listen and try to help. Unforetunately the "tech support" people (with the exception of a few) think Java is a brand of coffee. Hopefully they will get this new version of resin up soon because those errors drive me nuts! Keep in touch & let me know how you make out.......you wouldnt happen to be on thunder5 would you? Thats the server Im on and it can be REAL fussy at times! Take care

Actually the bug is in the code not in the Resin engine, however we already are in the process of upgrading to the newest Resin 2.0.5

Dont you just LOVE tech support people who can NEVER admit the problem is with them. Makes you F*&(*&%$ CRAZY! Anyway, supposedly Mike from Caucho said that the bug has been fixed in 2.0.5 so hopefully this nightmare will go away soon! Keep in touch.....it might be fun to trade stories from CWI & heaven knows with their tech support you need all the allies you can get......Have fun, stay well
