JDBC Driver Not Found error

Hello:

Crystal Reports 2013. Using Informix JDBC drive ifxjdbc.jar. Report was working before

Situation:

1. CRConfig.xml was edited so following was in Classpath:

....;C:\Program Files (x86)\SAP BusinessObjects\\SAP BusinessObjects Enterprise XI 4.0\java/lib/ifxjdbc.jar;${CLASSPATH}

and connection info edited:

<JDBCURL>jdbc:informix-sqli://xxx.yyy.local:50001/xxx:informixserver=xxx_ol</JDBCURL>

  <JDBCClassName>com.informix.jdbc.IfxDriver</JDBCClassName>

  <JDBCUserName>billy</JDBCUserName>

2. ifxjdbc.jar placed in the above directory listed in (1).

Get the JDBC driver not found error. Why do I get this error? I entered the path above like in the other entries--I also tried putting the ifxjdbc.jar in a simple directory like c:\myfolder\ifxjdbc.jar , and entering it just like that in the CLASSPATH. No joy.

Any ideas what the problem is?

Thanks!
