- 关于oracle调用webservice的问题 4C
-
在oracle的包里面调用delphi开发的一个webservice，第一次调用可以成功，然后就报错ORA-29532: Java 调用被未捕获的 Java 异常错误终止: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: oracle.j2ee.ws.saaj.ContentTypeException: Not a valid SOAP Content-Type: text/html
必须要断开oracle然后重新连接才可以，但是其他的开发工具调用确正常。
同样的写法，调用java开发的webservice就没有问题。
代码是这样的：
create or replace FUNCTION add_func1 (str1 IN VARCHAR2,
str2 IN VARCHAR2)
RETURN VARCHAR2

service_ sys.utl_dbws.service;
call_ sys.utl_dbws.call;

END;
