ORA-29541: class SYS.oracle/jpub/runtime/dbws/DbwsProxy could not be resolved
在oracle10.1.2中用function调用webservcie出现如下错误：
"ORA-29541: class SYS.oracle/jpub/runtime/dbws/DbwsProxy could not be resolved"
这是因为需要导入一些包（详情可参考http://www.oracle-base.com/articles/10g/utl_dbws10g.php）
First, download the latest copy 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)
Extract the jar file from the zip file into the $ORACLE_HOME/sqlj/lib directory.
# Load into the SYS schema.
export PATH=/u01/app/oracle/product/10.2.0/db_1/bin:$PATH
cd /u01/app/oracle/product/10.2.0/db_1/sqlj/lib
# 10gR2
loadjava -u sys/password -r -v -f -genmissing -s -grant public dbwsclientws.jar
# 11g
loadjava -u sys/password -r -v -f -genmissing -s -grant public dbwsclientws.jar
原文中提到也可以导入单个的schema，但是我导入后还是有问题。In Oracle 10g the UTL_DBWS package is loaded by default，所以我就用sys.UTL_DBWS.
我下载的是第二个包。
在导入的过程中正常情况下没有错误，那就要恭喜你了。可是事与愿违，经常会产生错误，所以当运行webservice代码时还会报上面的错误！！！
解决如下：
解压dbwsclientws.jar 找到oracle下的jpub/runtime/dbws整个目录，拷贝出来，重新打包，再重新单独导入这个包即可。将我重新打包的jar上传一下（看附件）
loadjava -u sys/password -r -v -f -genmissing -s -grant public dbwsproxy.jar
示例：
以下是我的wsdl：
WSDL created by Apache Axis version: 1.4
Built on Apr 22, 2006 (06:55:48 PDT)
--> <script></script>
下面是oracle function：

执行成功！
