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:
[code]

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?

Yes, it sounds as if there is still a problem with the javacomm installation. You may have not installed the lib files for linux, or your java.comm.properties file may have incorrect settings. Try reinstalling javacomm for linux here: [url]http://www.sun.com/download/products.xml?id=43208d3d[/url].]]> http://forum.infiniteautomation.com/forum/posts/preList/28/87.page http://forum.infiniteautomation.com/forum/posts/preList/28/87.page GMT http://wass.homelinux.net/howtos/Comm_How-To.shtml . I'll play around and see if I can get it working.]]> http://forum.infiniteautomation.com/forum/posts/preList/28/88.page http://forum.infiniteautomation.com/forum/posts/preList/28/88.page GMT
You should have downloaded a file called comm3.0_u1_linux.zip. Early versions of javacomm did not support linux, but now it appears they do. I would post the file here, but since i had to log in to get it, i doubt we're allowed to redistribute. If you're having trouble getting the file, let me know.]]> http://forum.infiniteautomation.com/forum/posts/preList/28/89.page http://forum.infiniteautomation.com/forum/posts/preList/28/89.page GMT http://forum.infiniteautomation.com/forum/posts/preList/28/90.page http://forum.infiniteautomation.com/forum/posts/preList/28/90.page GMT
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!
