1)load jar file

loadjava -r -f -verbose -resolve

-user xmlbook/xmlbook xmlparserv2.jar

2)load class file

loadjava -r -f  -user

user_name/password[@URL]

oracle/AAA/bbb/CCC.class

3)remove Java classes from the database

dropjava -r -f  -user

user_name/password[@URL] [option_list]

file_list

4)call Java存储过程

SQL> variable myString

varchar2[20];

SQL> call helloworld() into

:myString;

Call completed.

SQL> print

myString;

MYSTRING --------------------- Hello

world

5)Creating a PL/SQL Wrapper

The syntax

for creating this procedure is:

CREATE

[OR REPLACE] {

PROCEDURE procedure_name [(param[,

param ...])] |

FUNCTION  function_name

[(param[, param ...])]

RETURN

plsql_type]}

[AUTHID {DEFINER |

CURRENT_USER}]

[PARALLEL_ENABLE]

[DETERMINISTIC]

{IS

| AS} LANGUAGE JAVA

NAME ‘java_method (java_type[,

java_type] ...)

[RETURN

java_type];

where param is defined as:

param

:= parameter_name [IN | OUT | IN OUT]

plsql_type

some details are writen

6)use

jdeveloper IDE to load java class

run->deploy->new

deploy profile->general->deploy profiles->load java and java stored

procedure

-andresolve

Compiles

source files and resolves each class file as it is loaded. This option and

-resolve are mutually exclusive. If neither is specified, files are loaded

but not compiled or resolved. In general, this mode is not recommended

because it can leave classes that have unresolved references marked valid,

causing an error at runtime.

-debug

Generates debug

information. This option is equivalent to javac

-g.

-definer

Specifies that the methods of uploaded

classes will execute with the privileges of their definer, not their

invoker. (By default, methods execute with the privileges of their

invoker.) Different definers can have different privileges, and an

application can have many classes, so make sure the methods of a given

class execute only with the privileges they need.

Note that

Oracle8i Release 8.1.5 does not seem to conform to the Oracle

documentation; the default seems to be to run with definer

rights.

-encoding

Sets (or resets) the -encoding

option in the database table JAVA$OPTIONS to the specified value, which

must be the name of a standard JDK encoding scheme (the default is

"latin1"). The compiler uses this value, so the encoding of uploaded

source files must match the specified

encoding.

-force

Forces the loading of Java class

files, whether or not they have been loaded before. By default, previously

loaded class files are rejected. You cannot force the loading of a class

file if you previously loaded the source file. You must drop the source

schema object first.

-grant

Grants the EXECUTE

privilege on uploaded classes to the listed users or roles. (To call the

methods of a class directly, users must have the EXECUTE

privilege.)

This option is cumulative. Users and roles are

added to the list of those having the EXECUTE privilege.

To

revoke the privilege, either drop and reload the schema object without

specifying -grant, or use the SQL REVOKE statement. To grant the privilege

on an object in another user‘s schema, you must have the CREATE PROCEDURE

WITH GRANT privilege.

-oci8

Directs loadjava to

communicate with the database using the OCI JDBC driver. This option (the

default) and -thin are mutually

exclusive.

-oracleresolver

Binds newly created class

schema objects to the following predefined resolver

spec:

"((* definer‘s_schema) (* public))"

-resolver

are mutually exclusive.

-resolve

After all class

files on the command line are loaded and compiled (if necessary), resolves

all external references in those classes. If this option is not specified,

files are loaded but not compiled or resolved until

runtime.

Specify this option to compile (if necessary) and

resolve a class that was loaded previously. You need not specify the

-force option because resolution is done independently, after

loading.

-resolver

Binds newly created class schema

objects to a user-defined resolver spec. Because it contains spaces, the

resolver spec must be enclosed by double quotes. This option and

-oracleresolver (the default) are mutually

exclusive.

-schema

Assigns newly created Java schema

objects to the specified schema. If this option is not specified, then the

logon schema is used. You must have the CREATE ANY PROCEDURE privilege to

load into another user‘s schema.

-synonym

Creates a

public synonym for uploaded classes, making them accessible outside the

schema into which they are loaded. To specify this option, you must have

the CREATE PUBLIC SYNONYM privilege.

If you specify this

option for source files, it also applies to classes compiled from those

source files.

-thin

Directs loadjava to communicate

with the database using the thin JDBC driver. This option and -oci8 (the

default) are mutually exclusive.

-verbose

Enables

the verbose mode, in which progress messages are

displayed.
