Hi, I am developing a web where i use a phodget SBC.

When i run the application from within the development environment ( eclipse) everythin works fine, but when I depluy the SW to tomcat on the same machine i get the follownig error:
--------------------------------------------------------------
2011-apr-13 19:34:17 org.apache.catalina.core.StandardWrapperValve invoke
SERIOUS: Servlet.service() for servlet MooseFeeder Servlet threw exception
java.lang.ExceptionInInitializerError: no phidget21 in java.library.path
Could not locate the Phidget C library.
The Windows Phidget21 MSI must be installed

-----------------------------------------------------------------

I have installed the 64 bit MSI. the OS is windows 7 x64.

Maybe java servelets are not allowed to load JNI libraries? Or maybe they need to be configured specifically for it somehow?

I've been trying for the past week to get tomcat working with phidgets.

The problem is that tomcat uses a number of different classloaders to isolate each of the web applications.

You're supposed to be able to place the libraries in question in /share/lib, or /lib, but I'm either getting the error above, or the classloader can't find the phidgets jar.

I've tried running the phidgets via a web service, but it seems that the phidgets21.jar still tries to load the jni libraries, which fails.

I've admitted defeat I'm afraid. I'm going to run a standalone phidgets application, and then have the web application poll a shared database. A little inelegant, but it's more likely to work!
