A while ago, I posted about an error in attempting to write a client/server plugin for Servoy. Thankfully, that issue was resolved and we were able to create the plugin and have it work successfully in both the Developer as well as the client.
Unfortunately, it seems we’re back to square one. I know that the plugin was working as recently as this week. However, this morning, on doing testing, we realised that we were getting the following message: “The undefined has no properties calling directLeaveUpload”.
now, “directLeaveUpload” is the name of one of the methods in our plugin, so it seems that the plugin was not working properly or not being initialised properly or something of the sort.
This was not the first time that this happened. So I used the same approach as I did the last time - I recreated the jar file for the plugin and restarted the server.
On doing this, however, I began getting a RemoteException. At this point, I am totally stumped, since it was working previously, and nothing was changed.
So, any suggestions as to how to resolve this?
(If anyone needs further information, feel free to ask.)
We cannot really help like this. Don’t you have a log file where you see an exception? Then you could post that exception and we could see what goes wrong where.
My apologies… yesterday was a long frustrating day…
Here’s the latest portion of the log file. I’m now seeing that it’s saying that the port the RMI uses in use, but I even resorted to physically restarting the server and nothing has been added to that server in quite some time, so what could possibly be using that port ?
(Assuming that i’m even correct in my deduction of the cause of the problem, that is…)

Not only a table is missing but it looks like you db connections can not be opened.
The RMI error can either come from Servoy, when an address is already in use, or from your plugin when you try to set up your own RMI connection instead of using Servoy for that…
This is just a follow up to let everyone know the solution to the problem.
Just to recap, we’ve developed a plugin that allows us to use SAPs API (BAPI is the official term) to update it.
However, recently we started getting a Remote Exception. I figured out the problem, and the resulting solution.
The plugin we used required two dll files to be in the system’s PATH (this is Windows i’m talking about here). So, to use the plugin before, we had to ensure that those two dll’s were in the windows/system32 directory. However, Servoy was only finding the dlls when we ran the Servoy Server as an application.
To run the Servoy Server as a service and still get the plugin functionality, we had to place the two dll’s in the Servoy/service directory. That solved the problem.
This is just a heads up for anyone else who writes plugins that depend on external resources like dll’s.

You can load the dlls into your classpath dynamically. That will also solve your issue and make your solution, when needed, more transportable…
