JDBC problem on Linux

Hello, When I tried to run some examples that are delivered with the JDBC driver of informix, I got the following error: [root@Linux1 stores7]# java demo1 jdbc://172.22.0.100:1555:INFORMIXSERVER=linux_ se;user=informix;password=******** Could not connect to database server.... Invalid ASF API input parameters. Could not create database.... Could not populate database.... [root@Linux1 basic]# java CreateDB jdbc:informix-sqli://172.22.0.100:1555: INFORMIXSERVER=linux_se;user=informix;password=********>>>Create Database test.URL = "jdbc:informix-sqli://Linux1.gcc.dhl.com:1555:INFORMIXSERVER=linux_se" ERROR: failed to connect! ERROR: Invalid ASF API input parameters. java.sql.SQLException: Invalid ASF API input parameters. at com.informix.util.IfxErrMsg.getSQLException(IfxErrMsg.java) at com.informix.jdbc.IfxSqliConnect.<init>(IfxSqliConnect.java) at com.informix.jdbc.IfxDriver.connect(IfxDriver.java) at java.sql.DriverManager.getConnection(DriverManager.java:91) at java.sql.DriverManager.getConnection(DriverManager.java:149) at CreateDB.main(CreateDB.java:58) I made sure that the CLASSPATH was set correctly. I have informix SE on a redhat 5.1 system with JDK1.1.6? My sql host file is correct and my services file is also correct. Any one an idea what causes this problem Thanks, Wim
