<title>Description</title>
<para>This function calls the <function>jvm_ref_import()</function> function
to produce the XML, then transforms it to a set of CREATE TYPE statements
and executes them. The SQL names of the types are generated by retrieving
the fully qualified name of the Java class and substituting the . with _
(e.g.: java.lang.System becomes java_lang_System). The names of the static
members observer functions are composed by prepending the name of the
static member with 'get' so the static Java member stat_m is mapped to a
SQL static method getstat_m(). As a result it creates SQL type wrappers
for the specified Java classes.</para>
