oracle直接调用web services

 

在oracle中直接调用web services怎么操作，在网上查了很久，相关资料，比较少。

在这里整理一下，给需要的童鞋们做参考。。

Window下oracle开发webservices

1， 去oracle官网上下载dbws-callout-utility-10131.zip

地址：http://www.oracle-base.com/articles/10g/utl_dbws10g.php

2， 解压后放到oracle安装目录下的<oracle_install_dir>/sqlj/lib中；

3， 在命令行中利用loadjava命令(一般安装完jdk或oracle之后就会有)将jar包导入oracle对应的用户中：

loadjava -uuser/password@oracle -r -v -f -genmissing -s -grant public dbwsclientws.jar dbwsclientdb102.jar若为SYS用户，命令为：

loadjava -u user/password -r -v -f -genmissing -s -grant public dbwsclientws.jar dbwsclientdb102.jar

4， 如果未发现UTL_DBWS(可以在plsql中敲入sys.若未有utl_dbws显示，则需要进行初始化)，需要运行之前下载的包中dbws-callout-utility-10131/sqlj/lib/utl_dbws_body.sql及utl_dbws_decl.sql

5， 编写sql函数并发布

create or replace functionFUNC_GENERATE_LOGINNAME(content VARCHAR2,cellNumber VARCHAR2,sender VARCHAR2)

 return VARCHAR2 AS

 l_service       sys.utl_dbws.SERVICE;

 l_call          sys.utl_dbws.call;

 l_result         ANYDATA;

 l_wsdl_url       VARCHAR2(1024);

 l_service_name   VARCHAR2(200);

 l_operation_name VARCHAR2(200);

 l_input_params  sys.UTL_DBWS.anydata_list;

 l_xmltype_in       SYS.XMLTYPE;

  l_xmltype_out      SYS.XMLTYPE;

BEGIN

 l_wsdl_url       :='http://xxxx.xxxx.xxxx.xxxx:xxxx/project/axis/services.jws?wsdl';

 l_service_name   :='servicesService';

 l_operation_name := 'sendMessage';

 l_service        :=sys.UTL_DBWS.create_service(wsdl_document_location =>URIFACTORY.getURI(l_wsdl_url),

                                                 service_name           =>l_service_name);

 

 l_call := sys.UTL_DBWS.create_call(service_handle => l_service,

                                    port_name      => NULL,

                                    operation_name => l_operation_name);

                                

                                

 l_input_params(1) := ANYDATA.ConvertVarchar2(content);

 l_input_params(2) := ANYDATA.ConvertVarchar2(cellNumber);

 l_input_params(3) := ANYDATA.ConvertVarchar2(sender);

 

 l_result := sys.UTL_DBWS.invoke(call_handle  => l_call,

                                  input_params=> l_input_params);

 sys.UTL_DBWS.release_call(call_handle => l_call);

 sys.UTL_DBWS.release_service(service_handle => l_service);

 RETURN ANYDATA.AccessVarchar2(l_result);

EXCEPTION

  WHEN OTHERS THEN

   RETURN substr(sqlerrm, 0, 2000);

ENDFUNC_GENERATE_LOGINNAME;

6，看结果select func_generate_loginname('testTest','1234567','xxxxxx')from dual;

7对于其中出现的异常，最可能的就是出现权限不足，可以利用如下语句解决：

begin

dbms_java.grant_permission('DZZWPT', 'SYS:java.lang.RuntimePermission', 'getClassLoader', '' );

dbms_java.grant_policy_permission('DZZWPT','SYS','java.io.FilePermission','*');

---dbms_java.grant_permission('DZZWPT','SYS:java.lang.IllegalAccessException','getClassLoader', '' );

dbms_java.grant_permission('DZZWPT', 'SYS:java.lang.RuntimePermission', 'accessClassInPackage.sun.util.calendar','' );

dbms_java.grant_permission('DZZWPT', 'SYS:java.lang.RuntimePermission', 'setFactory', '' );

dbms_java.grant_permission('DZZWPT', 'SYS:java.util.PropertyPermission', 'HTTPClient.socket.idleTimeout','write' );

dbms_java.grant_permission('DZZWPT', 'SYS:java.net.SocketPermission', 'localhost', 'resolve' );

dbms_java.grant_permission('DZZWPT', 'SYS:java.net.SocketPermission', '192.168.21.203:80','connect,resolve' );

dbms_java.grant_permission('DZZWPT', 'SYS:java.lang.RuntimePermission', 'createClassLoader', '' );

end;

8，有帮助的语句

SELECT owner,status, count(*) FROM DBA_OBJECTS
WHERE OBJECT_TYPE='JAVA CLASS'
GROUP BY owner, status; 
select * from User_Objectst where t.object_type like '%JAVA_CLASS%' and object_name like '%DbwsProxy%';

SELECT   TEXT   FROM   ALL_SOURCE   
WHERE   TYPE   =   'PACKAGE'   and owner like '%XGXT%'

 

 

 

 

 

 

 

 

 

Linux   AIX系统下：

首先要已创建oracle的那个用户登录进去(官网上找到的资料，我就不翻译了)。

UTL_DBWS - Consuming Web Servicesin Oracle 10g

Ina previous article I presented a method forConsuming Web Servicesusing a basic SOAPimplementation. This article provides similar functionality, but this timeusing theUTL_DBWSpackage, which is essentially a PL/SQLwrapper over JPublisher.

First, download the latestcopy of the dbwsclient.jar file:

• Pre 10g:dbws-callout-utility.zip(10.1.2)
• 10g:dbws-callout-utility-10R2.zip(10.1.3.0)
• 10g & 11g latest:dbws-callout-utility-10131.zip(10.1.3.1)

Extractthe jar file from the zip file into the $ORACLE_HOME/sqlj/lib directory.

The jar file can be loadedinto the SYS schema for everyone to access, or into an individual schema thatneeds access to the web client.

# Load into theSYS schema.

exportPATH=/u01/app/oracle/product/10.2.0/db_1/bin:$PATH

cd/u01/app/oracle/product/10.2.0/db_1/sqlj/lib

# 10gR2

loadjava -uuser/password -r -v -f -genmissing -s -grant public dbwsclientws.jardbwsclientdb102.jar

# 11g

loadjava -u user/password -r -v -f -genmissing -s -grant public dbwsclientws.jardbwsclientdb11.jar

 

# Load into anindividual schema.

exportPATH=/u01/app/oracle/product/10.2.0/db_1/bin:$PATH

cd /u01/app/oracle/product/10.2.0/db_1/sqlj/lib

# 10gR2

loadjava -uscott/tiger -r -v -f -genmissing dbwsclientws.jar dbwsclientdb102.jar

# 11g

loadjava -uscott/tiger -r -v -f -genmissing dbwsclientws.jar dbwsclientdb11.jar

InOracle 10g theUTL_DBWSpackage is loaded by default. In Oracle9i thepackage must be loaded using the specification and body provided in the zipfile.

The function below uses theUTL_DBWSpackage to access a web services from PL/SQL. The URL ofthe WDSL file describing the web service is shown here (http://webservices.imacination.com/distance/Distance.jws?wsdl).The web service returns the city associated with the specified zipcode.

CREATE OR REPLACEFUNCTION get_city_from_zipcode (p_zipcode IN  VARCHAR2)

  RETURN VARCHAR2

AS

  l_service UTL_DBWS.service;

  l_call    UTL_DBWS.call;

  l_result  ANYDATA;

 

  l_wsdl_url         VARCHAR2(32767);

  l_namespace        VARCHAR2(32767);

  l_service_qname    UTL_DBWS.qname;

  l_port_qname       UTL_DBWS.qname;

  l_operation_qname  UTL_DBWS.qname;

  l_input_params     UTL_DBWS.anydata_list;

BEGIN

  l_wsdl_url        :='http://webservices.imacination.com/distance/Distance.jws?wsdl';

  l_namespace       :='http://webservices.imacination.com/distance/Distance.jws';

 

  l_service_qname   := UTL_DBWS.to_qname(l_namespace,'DistanceService');

  l_port_qname      := UTL_DBWS.to_qname(l_namespace,'Distance');

  l_operation_qname := UTL_DBWS.to_qname(l_namespace,'getCity');

 

  l_service := UTL_DBWS.create_service (

    wsdl_document_location =>URIFACTORY.getURI(l_wsdl_url),

    service_name           => l_service_qname);

 

  l_call := UTL_DBWS.create_call (

    service_handle => l_service,

    port_name      => l_port_qname,

    operation_name => l_operation_qname);

 

  l_input_params(0) :=ANYDATA.ConvertVarchar2(p_zipcode);

 

  l_result := UTL_DBWS.invoke (

    call_handle => l_call,

    input_params => l_input_params);

 

  UTL_DBWS.release_call (call_handle =>l_call);

  UTL_DBWS.release_service (service_handle=> l_service);

 

  RETURN ANYDATA.AccessVarchar2(l_result);

END;

/

Theoutput below shows the function in action.

SQL> SELECTget_city_from_zipcode('94065') FROM dual;

 

GET_CITY_FROM_ZIPCODE('94065')

--------------------------------------------------------------------------------

Redwood City

 

SQL> SELECTget_city_from_zipcode('94066') FROM dual;

 

GET_CITY_FROM_ZIPCODE('94066')

--------------------------------------------------------------------------------

San Bruno

注：

如果不小心将jar加载到了oracle的其他的用户下，可用dropjava 命令卸载已经加载的jar包。用法和loadjava的用户相同。
