Hi, I'm using JNI to have my resource adapter calling a dll. If I stick the dll + three other dependencies (also dlls) in the JBOSS_HOME/bin it is all working BUT if I package the aforementioned dlls into the rar, notwithstanding the messages (for each dll present in the rar) in the console like this: 2006-11-08 11:53:16,234 INFO [org.jboss.resource.deployment.RARDeployer] Loading native library: mylibrary.dll I eventually got | java.lang.UnsatisfiedLinkError: no MyFunction in java.library.path | Consider that I also tried to explicitly load the library with System.loadLibrary, but the result doesn't change. Any idea? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3984067#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
