Help is sincerely requested.
After further investigation, I found that if I run .jmethods and have
the listing below. I know that this driver works because I have a java
program using that loads data scrapped from the web every night.
The call to JDBC in my previous email is trying to create the instance
of the jdbc driver as my java code does.
ie.
static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
Class.forName(JDBC_DRIVER); // .newInstance() ;
conn = DriverManager.getConnection("jdbc:mysql://" + svr + ":3306/"
+ sqldb + "?user=XXXXXXXXX&jdbcCompliantTruncation=false");
Again, I appreciate any and all help.
Joe
