I'm upgrading a java program I created using SNMP4j that uses OIDs to get values from devices etc.
What I want to do now is make a jsp page that will create tables based on these devices we have polled the data from. I've done out the jsp page and was testing if it will create an amount tables equal to the number of devices were I got a strange error on running it.
Here is my jsp:
If no one knows SNMP4j thats fine, I was just wondering if the problem comes from the jsp side of things. Also, for technical reasons at the moment, Im running my Apache tomcat server on a router thats not connected to the internet (devices are connected by wire)
EDIT: I also "modified" the project from a java project to a java EE project by modifying the .project file, would that be an issue?
Hang on, I think I've figured out whats wrong. I can pass normal values such as ints and strings from my java classes but what I wanted originally, an arraylist of objects, was what caused the error. Is there a special way of using Arraylists I'm not aware of.
