JDBC classes too large

Question

I created an applet just to test to execute the
sqlj statements. The entire applet is using java
classes except for the registration of oracle
driver which is using the oracle classes.
DriverManager.registerDriver (new
oracle.jdbc.driver.OracleDriver());
The deployment file generated by Jdeveloper 2.0
is about the size of 503K. This file besides
containing the definition files and the applet
class, the rest are all oracle classes.
The applet is connecting to Oracle 8.1.5.
Has anyone encountered the same problem on the size of
jdbc classes?

Answer 1

Yes the JAVA application really takes up this amount! It is really akward. The DB doesn't take a real big amount of memory because of the buffer sizes I've set. I execute the java application as follow:
./java -server -XX:MaxHeapFreeRatio=5 -XX:MinHeapFreeRatio=20 -Xmx1512M dbTest
I'm really trying to keep the heap small because the JAVA application ( a gene expression processing application/server) takes big amounts of memmory when downloading data from the mysql database and the server is accesible by multiple users parallel. Though I'm still testing alone, so the memmory abuse is not a cause by other users.
