Using dropjava

The dropjava utility reverses the action of loadjava. It converts filenames into the names of schema objects, drops the schema objects, and finally deletes their digest table rows. Dropping a class invalidates classes that depend on it directly or indirectly. Dropping a source also drops classes derived from it.

Here is the syntax:

dropjava {-user | -u} username/password[@database]
  [-option_name [-option_name] ...] filename [filename] ...

where option_name can be one or more of many options, some of which are listed below:

{  {oci8 | o}
 | {schema | s} schema_name
 | {thin | t}
 | {verbose | v} 
 | {help}
 | {encoding}
 | {synonym}}

On the command line, you can enter the names of Java source, class, and resource files, SQLJ input files, and uncompressed .jar files and .zip archives, in any order.

Table 22-3 summarizes the common dropjava command-line options.
