Jboss7.1.1发布的web项目数据库类型转换失败，求帮助

[我喜欢吃包子]

最近公司要将jboss4.2升级到jboss7.1.1，现在其他问题都解决，系统正常启动，功能正常使用，但是有一个功能人员清单导入，这个是调用数据库pkg，pkg的入参包含了数据库数组，java在获取数据库原始连接，并将arrayList类型转换为oracle数据库数组类型时就报错了。具体代码和报错内容如下，请高手帮忙解决。ps:这个数据类型转换在jboss4和tomcat下都是正常使用的。
代码如下：
sql.xml中的语句：
<!-- 保存被保人临时信息 参数映射 -->
<parameterMap id="callProcedureSaveTempMap" class="java.util.Map">
<parameter property="prtNo" javaType="java.lang.String" jdbcType="VARCHAR" mode="IN" />
<parameter property="user" javaType="java.lang.String" jdbcType="VARCHAR" mode="IN" />
<parameter property="sourceModule" javaType="java.lang.String" jdbcType="VARCHAR" mode="IN" />
<parameter property="masterContNo" javaType="java.lang.String" jdbcType="VARCHAR" mode="IN" />
<parameter property="mode" javaType="java.lang.String" jdbcType="VARCHAR" mode="IN" />
<parameter property="insuredTempList" javaType="java.util.List" jdbcType="ARRAY" mode="IN" typeName="TYPE_IM_INSURED_TEMP_ARRAY" typeHandler="com.sunshine.cis.common.typehandler.InsuredTempArrayHandler" />

<parameter property="batchNo" javaType="java.lang.Integer" jdbcType="INTEGER" mode="OUT" />
<parameter property="resultCode" javaType="java.lang.String" jdbcType="VARCHAR" mode="OUT" />
<parameter property="message" javaType="java.lang.String" jdbcType="CLOB" mode="OUT" />
</parameterMap>

<!-- 保存被保人临时信息 -->
<procedure id="callProcedureSaveTemp" parameterMap="callProcedureSaveTempMap">
{call pkg_cis_insured_manage.p_save_insured(?,?,?,?,?,?,?,?,?,?,?)}
</procedure>

java代码数据类型转换：
public void setParameter(PreparedStatement ps, int i, Object parameter, String jdbcType) throws SQLException {
// 获取原始连接
System.out.println("开始获取数据库连接池原始链接==============");
Connection conn = ConnectionUtil.getNativeConnection(ps.getConnection());
System.out.println("获取数据库连接池原始链接==============："+conn);
@SuppressWarnings("unchecked")
List<InsuredTempVO> insuredTempList = (List<InsuredTempVO>) parameter;
System.out.println("开始转换被保人数组，讲list转换为oracle数组=======");
ARRAY insuredTempArray = getInsuredTempArray(conn, insuredTempList);
System.out.println("转换被保人数组，讲list转换为oracle数组=======："+insuredTempArray.length());
ps.setArray(i, insuredTempArray);

}

private ARRAY getInsuredTempArray(Connection con, List<InsuredTempVO> insuredTempList) throws SQLException {
ARRAY insuredTempArray = null;
System.out.println("================1=============："+insuredTempList.size());
if (insuredTempList != null && insuredTempList.size() > 0) {
System.out.println("==================2===============");
StructDescriptor structdesc = new StructDescriptor(TYPE_IM_INSURED_TEMP, con);
System.out.println("==================3===============");
STRUCT[] structs = new STRUCT[insuredTempList.size()];
System.out.println("==================4===============");
ArrayDescriptor desc = ArrayDescriptor.createDescriptor(TYPE_IM_INSURED_TEMP_ARRAY, con);
System.out.println("==================5===============");
Object[] result = new Object[4];
InsuredTempVO insuredTempVO = null;
for (int i = 0; i < insuredTempList.size(); i++) {
insuredTempVO = insuredTempList.get(i);
result[0] = insuredTempVO.getSerialNo();
result[1] = insuredTempVO.getPrtNo();
result[2] = insuredTempVO.getBatchNo();
result[3] = insuredTempVO.getProposalContNo();
STRUCT item = new STRUCT(structdesc, con, result);
structs[i] = item;
}
insuredTempArray = new ARRAY(desc, con, structs);
} else {
ArrayDescriptor desc = ArrayDescriptor.createDescriptor(TYPE_IM_INSURED_TEMP_ARRAY, con);
STRUCT[] structs = new STRUCT[0];
insuredTempArray = new ARRAY(desc, con, structs);
}
System.out.println("==================6===============："+insuredTempArray.length());
return insuredTempArray;
}

在把项目发布到jboss7上后，老是在这里就报错了：
StructDescriptor structdesc = new StructDescriptor(TYPE_IM_INSURED_TEMP, con);

求大神支招解决办法，困扰几天了

补充一下这个list集合是个对象集合，如果是字符是可以转换成数据库数组，不报错的。

有人遇到过类似的问题的吗，求助呀！！！！！！！！！！！！！！！！！！！！！！！！！！！
