Hi All,

Im running jRDC2 on a windows10 VM with paralles, my server starts up successfully and connects to the mySQL db. Whenever I execute a job from b4a I get the following exception:

Has anyone encountered this before?

Using:
jRDC2
httputils2 v2.01

MYSQL:
innodb_version5.7.13
protocol_version10
slave_type_conversions
tls_versionTLSv1,TLSv1.1

Any feedback appreciated

The problem is between the client and RDC. Are you sure that the client code is based on the latest version?

I was running on an older version, and ran an SDK update. It works now. Thank you

Hi All,

I also have this problem. What I did to ipgrade to jRDC2 for B4A usage was :

1. Replaced the ReqManager.bas with the latest version (And see that HandleJobAsync was in there)
2. Changed my code to Async call.
3. Compiled the B4A source with no errors
4. Started RDC (which supposedly should be replaced by jRDC2) Actually RDC is working fine with Apps not using HandleJobAsync
5. I tried to find the jRDC2.jar but could not find it, is there a compile needed from jRDC2.b4j, how I do this, I am not using B4J)
6. Till now I do not get the clue whats ment with 'older version' and running SDK As in the previous comment in this thread which
probably also can solve my problem


Thanks for attention

Hi Jan,

Open up android SDK and make sure that all your files are up to date: Like the installation mentions here in step 2:
https://www.b4x.com/b4a.html

Also jRDC2 is compiled using B4J (the desktop app)
https://www.b4x.com/b4j.html

Make sure to download JRDC2, and open it using B4J:
https://www.b4x.com/android/forum/t...-rdc-remote-database-connector.61801/#content

Check the code for JRDC and make sure your IP and port matched up.

Hope this helps.
