About get the org.apache.commons.net.ftp.FTPClient Object

Classic Servoy
1

Here I got a problem about getting the org.apache.commons.net.ftp.FTPClient Object.

I used to use Servoy 7.3.1, and get the FTPClient Object by using statment:

var ftp = new Packages.org.apache.commons.net.ftp.FTPClient();

It used to work properly. But After I upgrade the Servoy to 7.4.1, the system returns a cannot found class org.apache.commons.net.ftp.FTPClient Exception.
It seems that the common-net 3.3.jar is not included in the developer, so I copy the common-net 3.3.jar to the application_server/plugins. Then the problem seems be fixed.

However, when I deployed the solution on the Servoy Application Server, even I don’t include the common-net 3.3.jar, although org.apache.commons.net.ftp.FTPClient is available, the version included by the server is earlier than 3.0.
The reason being FTPClient.listDirectories() method doesn’t exist. And based on the apache common-net change log, this function has been added after version 3.0. So It seems that the server does not use the latest version of the common-net.jar.

I tried to put the common-net 3.3.jar to the application_server/plugins again and application_server/lib, it still does not work.

So has anyone faced the same problem before? How can I make the Servoy Applicaiton Server see the common-net 3.3.jar?

Your help is appreciated. Thank you very much, guys. :P :P

Hi,

First of all welcome to the forum, I see it’s your first post :)

Since you are installing jars on the server already to fix this issue why don’t you install the free FTP plugin from IT2Be instead. As far as I know it does the same and works with the latest Servoy releases.
You can find it at http://www.servoycomponents.com/plugins/ftp.php .

Hope this helps.

Thanks for help.

I don’t want to use too much plugins. I fixed the problem in the Servoy developer, but in the Serovy AppServer, the solution doesn’t work.

So, I still want to know how to install jars on the Servoy AppServer.

Thanks

I think I get a partial solution.
I install the it2be ftp plugin, then the servoy server can see the common-net.jar.
It seems the it2be ftp installation helped me to install the common-net.jar in the app server.

However, I still don’t know how to install external jars by myself.

Thanks for Roberts.

Hello,

Try with placing the JAR in the application_server/bean folder. Then you should be able to access it.
