Thank you for the response. Below are some more clarifications and my questions:
"Good, dynamic addresses are ok, DNS is ok. However, you need to know the host names then, right? How do you know those? " In the digi Connect ware manager we have both IP address and the host name. We'll send the host name and DNS server will provide the IP for the host name. "Then you need to know the format of the message (both request and reply). Is it already enforced by those who wrote the code on the digi or is something for you to define? At this point this is the most important question you need to answer. So how does the message you send look like, and what's the content of the response? " The message format has been enforced (both request and reply). Here is an example of the command that will be sent to the digi device: C0 80 05 00 54 72 C0 Digi will relay this message to the computer onboard truck which is connected to the digi via serial port. digi will get the response ,shown below, which it will send to the client: C0 81 1F 00 00 00 00 00 3E 00 01 73 9F 00 50 00 06 07 40 46 EE B1 99 F6 3A 00 4E BA AE 6F 33 6D C0 Similarly , there are many other command/messages that are sent/received to/from digi device. "The only thing you need is to use either camel-http (if you use https), or camel-netty or camel-mina if you prefer raw IP connections. From your description, if I were to choose, I would go with https (and use camel-http). " At present I would like to try/test both options camel-netty or camel-mina and camel-http. my questions: "The nugget above points to a dynamic router [1], probably a routing slip [2] as being part of the solution." Q. I didn't get what you mean. No body has pointed dynamic router/routing slip. Who is nugget? you mentioned that "Camel should be your client program". Q. All I know is that I'll have to do something like this: <from uri="mina:tcp://IP Address:8888?textline=true&sync=true"/> My question is that prior to saying from, I will need to pull the host name from the database, then get the IP for the host via DNS server then establish the connection with digi using the IP address and port. Then I will send a command, get the response. Then send the second command, get the second response. I will have to do this for all the digi devices that are up and connected to the trucks. Where should I put all this logic and how will it work with the from end point. One I know how to put the bits together I will test it using "some endpoints" with the real message format. Thank you very much for your valuable feedback. I am anxious to see CAMEL in action for my project. -- View this message in context: http://camel.465427.n5.nabble.com/Remotely-pulling-messages-using-CAMEL-tp4971149p4994444.html Sent from the Camel - Users mailing list archive at Nabble.com.
