RE: Tomcat 7 (7.0.54) java.lang.ClassFormatError: Truncated class file

2015-07-22 Thread Rahul Kumar Singh 
Dear Christopher,

The solution is fine, but first thing we need to identify the root cause.
If it is the problem of "loading a JSP-based class file." Why it is happened in 
production environment?
Any solid reason ?

Regads,
Rahul Kumar Singh

Well,

it looks like you are having a problem loading a JSP-based class file. You 
could write a script to try to load each JSP .class file to see which one is 
broken. Something like this:

$ for class in $(find . -name "*.class") ; \
  do \
echo $class \
javap -classpath [classpath] $(sed -e 's/\.class//' ) \
  done

This is unrelated to your real problem.

Yep: "working as designed" means "we designed it to work with our own
products under the conditions we ave specified, and nuts to you if you
want something different." Otherwise known as the "standards be
damned" design principle. I don't know why anyone is surprised, here.

South River Technologies' WebDrive. It's a remote filesystem driver
that creates a drive letter which maps to some remote share and
supports (proper) WebDAV(S) including proper file-locking (as well as
local caching of files with lots of configuration options),
(S)FTP/FTP(S), Amazon S3, Google Drive, DropBox, SharePoint, and
something called "OneDrive", which I've never heard of.

I've never used WebDrive for anything other than WebDAV; I'm not sure
how great it is for those other protocols, but I suspect it will
perform well. Their tech support folks were even kind enough to walk
one of my users through the installation and configuration of the
software when she called to ask how to download the installer.

http://www.southrivertech.com/products/webdrive/

(Note: I have no financial interest in SRT. I'm just a happy user of
their product.)

+1

I just sent an email to the folks running http://webdav.org/ about
Tomcat itself as well as WebDrive.

Since the URL you presented will not be mapped to your /zedlabs
application, you'll have to make a custom error page in the ROOT web
application to do this for you.

Specifically:

1. Ensure that webapps/ROOT exists (or that a ROOT web application is
otherwise deployed)

2. Create your custom 404 error page in the ROOT context, for example
   under ROOT/errors/404.jsp

3. In ROOT/WEB-INF/web.xml, define a custom  for 404,
   and point it to the resource you created in step #2 above

Hope that helps,

NullPointerException in NioEndpoint under load (but not only)

2015-07-22 Thread Antoine Bonavita 

Hello,

Before I start with my question and stack trace, let me give you a bit 
of context:

* Tomcat 7.0.61
* OpenJDK1.7.0_79
* Debian7
* Tomcat is running "behind" an nginx server (reverse proxying).
* As we have pretty stringent constraints on response time, nginx is 
configured to reply to the browser after 2s if it has not heard back 
from Tomcat.
* As implied in the email subject, we are using the http-nio connector. 
This is because our code is calling many webservices in parallel and we 
don't want to be stuck waiting for one of them (after 300ms we timeout 
the request and consider they will not answer).


Now, my problem is that once in a while (with a higher probability under 
load), I get this exception:

Well,

it looks like you are having a problem loading a JSP-based class
file. You could write a script to try to load each JSP .class file to
see which one is broken. Something like this:

$ for class in $(find . -name "*.class") ; \
  do \
echo $class \
javap -classpath [classpath] $(sed -e 's/\.class//' ) \
  done

This is unrelated to your real problem.
