Error conecting to MySQL DB
Hi all,
I'm trying to connect to a MySQL db using:
Class.forName("com.mysql.jdbc.Driver");
and I get the error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/aspectj/lang/Signature
I've searched the forums (and web) and its a problem others have had to with classpaths not being set correctly - however the mysql-connector-java-5.0.4-bin.jar I downloaded does not include the path:
org/aspect/lang/Signature
I've download 4 different versions of it and they all have the path:
org\gjt\mm\mysql\
and in that directory isDriver.java.
I'm very new to Java (you may have already guessed that... ) - can anyone shed any light on the matter?
big thanks for any advice,
Des

I italicized a part of your post. According to your post this seems to be a problem regarding AspectJ not MySQL. It seems you wish to use AspectJ but have not included its jarfile(s) on your classpath.
I'm only guessing that you are trying to use AspectJ, but as far as I know, the MySQL drivers themselves do not require it. I believe it would be a violation of the JDBC driver standards for the Driver to require it, but I may be mistaken.
