I have a modified B4J server that compiles and runs fine.

Thought I would try the new ability non-ui programs as a standalone package.

I ran "Build Standalone Package" I copied my 'config.properties' file to .....\Objects\temp\build\bin.
I go back to .....\Objects\temp\build and run the executable and I get the following errors.

They look identical to me except one fails and one does not.

Any help appreciated.

Hi there...
do you run it at the same pc you ve tested before?

or copying to another... and then tested it ? if this is what you do just copy your database (with the way must be sql backup) + install database drivers+(mysql/mariadb/mssql) + copy config.properties to the right folder and edit with username/password or what else need..

Of course. All on the same computer, using the same config file. Nothing is moved anywhere except the config.properties file gets copied to bin after creating the package.
Same computer same SQL Server Instance same database same config.properties.

bin? if the config.properties was on a folder into the project... for example

...if was in c:\a\b\config.properties must go in c:\a\objects\b\config.properties

...if was in c:\a\config.properties must go in c:\a\objects\config.properties

....in objects not in bin... :-(

I started with it in \build and got the error that it couldn't find the \Objects\temp\build\bin\config.properties file. So I put it in the \bin directory and that issue went away.
If you look at the two logs I posted they appear to me to be identical until "Unable to connect."

Actually, to be pedantic, you didn't say what version of B4A you were trying it with.

I apologize for being unclear. what I meant by that was, before 9 you could NOT create a stand alone package. It would would not let you do it. What I DID say was that I thought I would try the new ability to create stand alone packages which, by definition means I must be using 9.

Put a big smiley face here and a giant grain of salt. It is late, I am tired and I keep making the stupid mistake of posting when I am tired.

agraham, your posts have helped me enormously over the years, so let me just take the time now to say thanks for all of the help you have provided. I am always grateful for your advice.

The current jServer library isn't compatible with the modules system. You might be able to get it working but some features might not work.

Try to add this:
Code: 
#PackagerProperty: IncludedModules = jdk.charsets
Click to expand...

Didn't do it. Thanks for taking a look. Here is the log after adding the line. I can work with the batch command. An exe would just be cleaner for our customers.
