I did it. I mean, in the file there was already the "auto_homed_prefixes" section inside server_config block.

I just check it but this is not the error (actually, hdl-dbtool works fine).

Any other idea?some parameter I forgot to change in the class that extends from HandleStorage or something?.

Thanks.

You have to "home the prefix". This is done by sending a special request to the server, which tells the server to consider itself responsible for the prefix.

Easiest way to do this is to add to your config.dct "server_config":

"auto_homed_prefixes" = ( "0.NA/55555" )

Works fine now, or at least connect ok.

Was the server address in the config file as well as the credentials to authentaticate.

I can manage handles with dbtool (list, create and modify handle) and check the result in the mongo database, however using the same java source code that I have been using now I get this error: SERVER NOT RESPONSIBLE FOR HANDLE: That prefix doesn't live here.

As I said is to strange, because dbtool works fine..should I change something in the source code? For example, to get a handle;

public HandleValue[] getFullHandle(String hid){
try {
return new HandleResolver().resolveHandle(local_prefix+"/"+hid, null, null); }catch(Exception e){
System.out.println("ERROR:"+e.getMessage());
}
return null;
}

THe local prefix is 55555. I try with 55555/, adding 0.NA/55555..but still get the same error (prefix doesn't live here).

Any suggestion?

Thanks.

I don't know why this would have changed for you. Presumably a handle client is being initialized before the server listeners are available, but it's not clear why that is happening only when you use the custom storage. The problem is merely cosmetic, however.

Yes exactly.

So far I have been working withouth any problem with a classical instance of Handle (Berkeley)...

The error connection could be because the configuration (config file) or related with source code?.

Thanks.

You can probably ignore the "Error refreshing root info". On startup the handle resolver tries to connect to the GHR to see if there is updated GHR information. Since you are trying to connect to 127.0.0.1 I assume you have configured your handle resolver to send GHR requests to localhost?

Yes, that was what I did but didn't work.

The error was "Unsupported major.minor version 52.0". Recompile with v7 and now works fine.

I already have errors but I asumme that are related with my code or even firewall:

Error refreshing root info: HandleException (CANNOT_CONNECT_TO_SERVER) 127.0.0.1: java.net.ConnectException: Conexión rehusada
HandleException (CANNOT_CONNECT_TO_SERVER) 127.0.0.1: java.net.ConnectException: Conexión rehusada

Thanks.

Indeed, the key is: java.lang.ClassNotFoundException: net.handle.server.MongoDBHandle

You can add the dependencies for your custom storage to the "lib" directory of the Handle.net software distribution, which should allow the software to find them.
