我的应用程序在我的本地tomcat服务器上正常运行。但后来我通过制作war文件在WebSphere中部署了它。部署之后，每当我尝试使用 StructDescriptor 调用存储过程时，如下所示，我将获得ClassCastException。以下是我的代码段：
StructDescriptor projectTypeDesc = StructDescriptor.createDescriptor(
"FRA_DATA.REGION_TYPE", st.getConnection());
STRUCT[] structs = new STRUCT[filterDTO.getRegion().size()];
for (int i = 0; i < filterDTO.getRegion().size(); ++i) {
int str = (int) filterDTO.getRegion().get(i).intValue();
Object[] objects = new Object[] { str };
STRUCT struct = new STRUCT(projectTypeDesc, st.getConnection(),
objects);
structs[i] = struct;
}
ArrayDescriptor arrayDescriptor = ArrayDescriptor.createDescriptor(
"FRA_DATA.REGIONS", st.getConnection());
arrayList.add(new ARRAY(arrayDescriptor, st.getConnection(), structs));
抛出的错误是：

在数据库中创建的对象如下：
CREATE OR REPLACE TYPE region_type AS OBJECT (region NUMBER);
CREATE OR REPLACE TYPE regions AS TABLE OF region_type;
我尝试搜索不同的表单，但没有得到任何解决方案。请帮忙。
答案 0 :(得分：0)
使用WSCallHelper.getNativeConnection“解包”WSJdbcConnection中包含的OracleConnection：
StructDescriptor projectTypeDesc = StructDescriptor.createDescriptor(
"FRA_DATA.REGION_TYPE",
WSCallHelper.getNativeConnection(st.getConnection()));
