Where do you put the Oracle's JDBC Thin Driver for Crystal Reports?


Where do you save the jdbc thin driver for Oracle? I have tried jre/lib/ext but my program, Crystal Reports keeps saying it can't find it. I figure I have saved it in the wrong place.

If I go to a command prompt and use:


C:\TEMP>java oracle.jdbc.OracleDriver

Oracle JDBC 4.0 compiled with JDK6 on Fri_Aug_26_08:19:15_PDT_2011<br /> Default Connection Properties Resource<br /> Wed Oct 12 14:02:05 EDT 2011


So I know it is there.

edit: Since I could not get CR to work I tried a console app but it cannot find the driver:

package javaapplication1; public class JavaApplication1 { public static void main (String[] args) throws Exception { Class.forName ("oracle.jdbc.OracleDriver"); Connection conn = DriverManager.getConnection ("jdbc:oracle:thin:@myserver:1521:mysid", "myid", "mypass"); // @//machineName:port/SID, userid, password try { Statement stmt = conn.createStatement(); try { ResultSet rset = stmt.executeQuery("select BANNER from SYS.V_$VERSION"); try { while (rset.next()) System.out.println (rset.getString(1)); // Print col 1 } finally { try { rset.close(); } catch (Exception ignore) {} } } finally { try { stmt.close(); } catch (Exception ignore) {} } } finally { try { conn.close(); } catch (Exception ignore) {} } } }

edit: On my computer it is here:

C:\Program Files\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\win32_x86\jdk\jre\lib\ext


Just put it in the application's runtime classpath. The file system paths covererd by the classpath depends on how you're executing the application.

Based on your question history I see that you're using JSP/Servlets, which thus means that it's a web application in flavor of a WAR file which runs in an appserver. In that case, the JAR file needs to go in webapp's own /WEB-INF/lib folder or in the appserver's own /lib folder.

If it were a plain vanilla Java application .class file with a main() method which is to be executed by java command, then you'd have to use the -cp (-classpath) argument to specify the runtime classpath. It takes a collection of (semi)colon separated disk file system paths.

If it were a JAR file, then it had to be specified in the Class-Path entry in JAR's /META-INF/MANIFEST.MF file. This can be relative to the java -jar command's working directory.

You should really avoid putting 3rd party libraries in JRE's /lib folder. This would potentially introduce classpath problems with all other existing applications which use the same JRE.
