Non supported character set error when using refCursor in java service

I am developing an API with its base code inside of a jar file, the code connects to our oracle database, but when i try to run any code that uses a refcursor like so :

String sql = "BEGIN\n" + 
"  BS_BOJ_CMS_FASTMSG_API.Get_CMS_Parameters("  + 
"P_RESULT => ? " +
"  );\n" + 
"END;" ;
stmt  = conn.prepareCall(sql);
stmt.registerOutParameter( 1 , OracleTypes.CURSOR);
ResultSet rs    = (ResultSet) stmt.getObject(1);
while ( {
if ( rs.getInt("ID") == 1 )
      x= rs.getString("VALUE");

it returns the error “Non supported character set (add orai18n.jar in your classpath): AR8MSWIN1256”
the problem only seem to arise on out dev server, but it works fine on my local machine .
I’ve included the following jars with the package : ojdbc8.jar, orai18n.jar

and they are the same i use on my machine , but still no luck .
take note that my machine and the server connect to the same DB.


what is your IS version, JDBC Adapter version and Oracle Database version?
Please check the META-INF/MANIFEST.MF files from the mentioned jars to see if they refer to the same JDBC Driver version.

Hopefully, your local machine and your server connect to different users/schemata on your DB as mixing several server in one database schema set is not recommended except for clustering purposes where it is required.

Are you certain that doing this in Java is necessary? Is there a specific constraint such that JDBC adapter services won’t do what you want?
