B$AServer issue

[sconlon]

The app I am developing has a print function which I first implemented successfully using a bluetooth printer. However, I would rather not have the expense of providing a bluetooth printer to my clients so having read the posts on B4AServer I thought it might be a good alternative. I am not very familiar with java, php, webservers etc so I found it quite difficult to understand the setup of the system and haven't yet got it working - the current error given in the log is "Address already in use" which occurs on the line "server.Initialize(B4AServer.ServerPort, "server")" in the Service_Create sub in B$AServerService module. However, as I will be installing the app in clients sites that may be running PCs with anything from Windows XP to Windows 8 I am beginning to think that the whole system might not work across that range of systems. For example, I don't know about installing a board web service on an XP machine. Could anyone give a view on whether or not this would be feasible and what difficulties might arise?

You can change the port to a different one by changing B4AServer.ServerPort. It is a device local port.

Using B4AServer requires some networking knowledge. You can however run one board server for all installations. It can be installed on any accessible computer.

I changed the port to 7891 and am now getting the following error in the log.

Error connecting: org.apache.http.conn.ConnectTimeoutException: Connect to /192.168.1.35:80 timed out

The 192.168.1.35 is the internal IP address of my PC which I have put in the B4AServer.Initialize command

B4AServer.Initialize("http://192.168.1.35/android/b4aserver/b4a_server.php", servername, "Main"

and set servername to the same as I have in the config.properties file. I have copied the files from your B4AServer-Desktop.zip file into folder c:\android\b4aserver and changed the config.properties file as stated above. But there is still obviously something I am missing!

Are you running a web server on your desktop?

 

[sconlon]

No. I thought that if I was using your board web server (during the development phase) I would not need one locally.

 

[Erel]

The URL in the initialize method should point to the board server. In your case it should point to the one hosted here.

 

[sconlon]

So just that I understand this correctly, if I am using your board webserver the only things I need on my local desktop are the b4aserver.jar, the run.bat file and a subfolder called files plus of course printhtml. If I am using my own webserver on it I will need the b4aserver.php and config.properties and the same things on my desktop PC but with the initialise URL pointing to my own webserver.

 

[Erel]

You are correct. Note that the board server hosted here should only be used during development.

Hi,
I have implemented a PC server - b4a client over Wi-Fi. Then client just control the flow of the programming running on the server in vb6 (basically by pressing appropriate buttons). What changes can do in order to use interne connection instead of WiFi? Is it enough to point the client to servers' http//IP: port? Also does anybody know how many connection mswinsocket can handle?
Thank you in advance,
Mike

B4AServer cannot be used over the internet as the desktop server connects to the device. Mobile networks do not allow you to make incoming connections.

 

[mbatgr]

But the device will work as a b4a client while the desktop PC as a vb6 server.

But the device will work as a b4a client while the desktop PC as a vb6 server. Do I put this question at a wrong thread ?-)

 

[Erel]

Are you asking about B4AServer? If yes, then it cannot be used over the internet.

 

[mbatgr]

ok, I got it...thank you Erel. B4Client can do that?

[Erel]

What is B4Client?

 

[mbatgr]

Erel you speak like a bot. it is a simple client b4a app .

 

[Erel]

No, the B4A server and the client must be connected over a local network.

Thanks Erel
