oracle直接调用web services

oracle调用C#开发web services

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

地址:https://oracle-base.com/articles/10g/utl_dbws-10g(注意请根据自己oracle的版本来选择下载对应的jar)

2,  解压后放到oracle安装目录下的/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 -u user/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

(本人每次都会使用SYS用户权限比较大,在Win7与Win2008之后的系统开始命令行窗口的使用尽量使用“管理员模式”,安装时会产生拒绝访问的情况,有一种可能就是安装的Oracle数据库具备功能或者可以把Oracle服务关了再试试(这句有机会真的可以试试))

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 function FUNC_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';(这里一定要加?wsdl)

  l_service_name   := 'servicesService';(就是我们*.asmx的那个类名)

  l_operation_name := 'sendMessage';(就是我们具有WebMothed属性的方法名)

  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);

END FUNC_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.FileP ermission','*');

---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.以上为官方实例,接下来我们来试试HelloWorld

 1).首先,我们要对自己写的WebServer做一些修改,

   在WebServer类前面把Namespace设为空,且把[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]


根据WebServer中的说明来确定输入参数、输出参数的格式


l_xmltype_in 的值就是

输出就是


  Hello World
