Packages for Java user-defined routines
Various packages can be used to create Java™ user-defined routines (UDRs).
UDRs can use all the basic nongraphic Java packages that are in the software development kit for Java.
UDRs must use the server-side HCL OneDB™ JDBC Driver to access the database. The server-side driver is shipped in a JAR file that is in $ONEDB_HOME/extend/krakatoa/jdbc.jar. UDRs can use most HCL OneDB extensions to the JDBC specification.
The HCL OneDB extensions are in the com.informix.udr package. Such extensions include logging, tracing, iterator support, and invocation-state management.
