Offline data management in OFBiz web POS

[deepak nigam-2]

Hello all,

I hope everyone is doing well in this tough time of the global pandemic.

Is there any support for managing the data offline in OFBiz web POS?
Suppose the scenario wherein the internet connectivity got dropped for a
few minutes, still, the business wants to use the POS system and continue
its operations. Any possibility of achieving this requirement?

Thanks & Regards

Hi Deepak,

One solution could be to run the OFBiz instance that is used to host the
WebPOS component in a LAN.

Hi Deepak,

You can refer following document
https://cwiki.apache.org/confluence/display/OFBIZ/Sync+Setup+Notes+and+Example

>>Is there any support for managing the data offline in OFBiz web POS?

I think we don't have any support for offline order taking, if you want to
use offline for the web, you can use serviceworker.

Hello all,

Is there any document for enabling RMI in OFBiz?  As per OFBIZ-6942
<https://issues.apache.org/jira/browse/OFBIZ-6942>, RMI was disabled due to
Java serialization issues. I also tried to revert the changes on local by
referring to https://markmail.org/message/dukv5glk3elilo5z, but it seems
that the file/code structure has been changed now.

I can trigger the RMI service host on the same machine (localhost:1099)
successfully, but it is giving connection error for OFBiz another server
deployed in the same LAN. I have confirmed that another server is
accessible for my machine.

Thanks in advance.

Hi Deepak -

Is rmiregistry running on the remote OFBiz server? Secondly, the remote
server must allow incoming remote connections on default 1099 port (if at
all this is the port rmiregistry is started on). Try to do telnet on the
port and see if it is even allowing connections.

Best,
Girish

Hi Deepak,

A search in the OFBiz wiki will go a long way. Here is the uri:

Thanks Girish.

Yes rmi-registry is running on the remote service. I have also verified
that the port 1099 is open on the remote server. I am getting the following
error on running the 'testRmi' service from my local machine:

The Following Errors Occurred:

Service dispatcher threw an exception:RMI Invocation Error (Connection
refused to host: 127.0.1.1; nested exception is: <br/>
java.net.ConnectException: Connection refused (Connection refused))

I have made changes necessary changes in serviceengine.xml for main-rmi and
entity-sync-rmi service location i.e. replaced localhost by remote server's
IP address. However from the above error it seems that it is still pointing
to 127.0.1.1.

It certainly looks like it is still trying to connect to the local server.
I would suggest using a debugger inside RmiServiceEngine and then try to
see what values the variables hold at the runtime.

Best,
Girish
