M@,

You're absolutely right, the FAQ they include appears to be a bit dated. I've got it working with the download from sun though. I ended up having to make a symlink from the <jdk>/jre/javax.comm.properties file to the <tomcat>/webapps/ROOT directory for Mango to find it. I'm sure there's a more elegant way of doing that, but for now I'm happy.

Thanks for bearing with me!

Edit: Reading through the faq in the linux release, it appears that JavaComm doesn't actually support linux. There appears to be a workaround at http://wass.homelinux.net/howtos/Comm_How-To.shtml . I'll play around and see if I can get it working.

Hey guys, great looking software.

After installation today I ran up against the comm.jar issue. After moving comm.jar to JAVA_DIR/jre/lib/ext, the error I received while trying to add a data source changed. Here's what I'm getting now:

org.springframework.web.util.NestedServletException: Handler processing failed; nested exception is java.lang.UnsatisfiedLinkError: com.sun.comm.SunrayInfo.isSessionActive()Z

OS: linux
Java version: 1.6.0_01-b06
Tomcat version : 5.5.23

It looks like it might still be related to the comm stuff. I'll be using modbus tcp for communication.

Any ideas?
