Exception : Driver Class not found

Question

We have the following configuration : JDBC 2.0 thin client
drivers, on apache 1.3.4, Sun spark 2.6, with Jdk 1.1.6 and JSDK
2.0. The drivers are installed in
$ORACLE_HOME/oracle/jdbc/driver, which is included in the
CLASSPATH as well.
Its generating the exception while we do,
DriverManager.registerDriver(new
oracle.jdbc.driver.OracleDriver());
We have tried by coping the particular class file to the working
directory. Its still not working. What can be wrong & where?
null

Answer 1

I don't believe /etc/profile gets called from cron. If you were to add
#!/bin/shas the first line of the script, it should get called though.
But you should really modify the script by adding the above line and then changing:
java GenerateRSSto
java -cp /usr/local/tomcat/webapps/ROOT/rss/xml:/usr/local/tomcat/webapps/ROOT/WEB-INF/lib/mysql-connector-java-5.0.5-bin.jar GenerateRSSThat of course assumes that GenerateRSS declares no package. If it declares the package "xml", then remove "/xml" from the above. If it declares package "rss.xml", then remove "/rss/xml" from the above.
Declaring a classpath in /etc/profile as above, is a bad idea (at least when including Drivers and/or other "special" packages). What happens if later applications need a different version of the same driver, and this application, and that one can't use the same version, for whatever reason? One of the two won't work, that is what will happen.
A classpath should always be declared as close to the execution as possible. Whether that is setting CLASSPATH in an application server, placing the jar in the WEB-INF/lib of an application, declaring a CLASSPATH in a script before executing java, or using the -cp option depends on the situation, but one of those should always be used.
