DBDATE using JAVA/NT/JDBC <-> IDS/UNIX

Hello out there, I'm writing a Java-application using jdk1.3 / Windows NT. This application contains an input form (like 4GL-Forms) which is used to build a wherestring. This wherestring has to be send through informix-jdbc 2.x (minor versions also tested !) to IDS 7.31x on an UNIX-server. After 'inputting' some date-values the resulting wherestring looks like: SELECT COUNT(*) FROM mytable WHERE mydate = '16.03.2000' (European Date Format)Sending this string through the JDBC-Connection results in an 'invalite date'-Error (-1204,-1205...) on IDS. Typing the same select manually using dbaccess on the unix server results in no error, because DBDATE is set to DMY4. I tried to set DBDATE on Windows-NT using SETNET32, Registry and System-Environment, but I didn't manage to get JDBC to use these settings. Any hints ? CU, Chris
