JavaScript to Java Class Conversions

Appendix B Converting SSJS Applications 101

JavaScript to Java Class Conversions

The objects used in an SSJS application must be converted to classes in Java. Table

B-2 can help you convert these objects.

SSJS includes a special library to handle database connectivity. Since JSPs are Java,

all database connectivity is handled through JDBC. JDBC database drivers are

available directly from the database vendors. It is a good idea to use pure Java

(type 4) drivers whenever they are available. Table B-3 lists the database

connectivity classes.
