Check this out:
The B4J-Bridge creates a folder called Tempjars on the remote device.
The server app (when connections are made) is looking for the www folder (and file index.html), which by default is not created by the B4J-Bridge.
To remediate:

• Logon to your remote device
• Select the Tempjars folder
• Copy the www folder from the B4J project folder Objects/www to Tempjars/www
  
• Start B4J, reconnect to the B4J-Bridge, start your app and connect via browser ip : port

Hi,
I followed exactly the steps that you have shown me but when I try to connect with a browser using IP_addressort I get the following message:

HTTP ERROR: 404
Problem accessing /. Reason:

Not Found

Can you share your code as easier to check.

Based on the error you have copied the www folder to the wrong place.

/home/pi/b4j/tempjars

Whenever you run a program a file named AsyncInput1 or 2 will be created on the target machine.

I solved the problem. The path where copy the folder www was /home/pi/tempjars instead of /home/pi/b4j/tempjars.

Thanks.
