Hi,
I am trying to synchronize files between client and server (using the SampleConsoleClient(-Server) with the FileNodeManager and the FileSyncClient
The files on the server get synchronized to the client, but the files on the client don’t get synchronized to the server.
Furthermore the client tries to synchronize the received files from the server back to the server.
————————————————-
ClientCode:
protected void loadFile(NodeId nodeId) {
FileSyncClient fileSync = new FileSyncClient(client);
try {
fileSync.addSyncedFolder(nodeId, System.getProperty(“user.dir”) + “/FileFolder/Client”,
FileSyncClient.SyncFolderDirection.ReadWrite);
} catch (Exception e) {
e.printStackTrace();
}
fileSync.setMonitorInterval(1000);
}
————————————————-
fileSync.addFile throws the same exception as the stack-trace below
————————————————-
ServerCode:
private void createFileNodeManager() throws StatusException {
// TODO
fileNodeManager = new FileNodeManager(getServer(), “http://prosysopc.com/OPCUA/FileTransfer”, “Files”);
getServer().getNodeManagerRoot().getObjectsFolder().addReference(fileNodeManager.getRootFolder(), Identifiers.Organizes, false);
fileNodeManager.setAllowWrite(true);
fileNodeManager.setMonitoringInterval(1000);
File serverFileFolder = new File(System.getProperty(“user.dir”) + “/FileFolder/Server”);
FileFolderType folder = fileNodeManager.addFolder(serverFileFolder);
fileNodeManager.startMonitoring();
}
————————————————-
Adding files to FileFolderType folder with folder.addFile…. doesn’t work either (addFile returns false, no exception is thrown)
————————————————-

Yes, the server does not enable AddNodes service by default, which is required for the client to be able to add new FileType nodes in the server.
To enable it in your server, use
You may further limit the adding using the NodeManagerListener in each NodeManager, if necessary.
Note that synchronising files is rather complex in practice due to the file system issues, and the SDK objects are not 100% accurate in noticing changes in the files and synchronising them. But, go ahead experimenting and seeing how it works in practice for you.
In general, the synchronisation from the server to the client should be more reliable.
And feel free to keeping us up to date how it works for you.
