ClassCastException:org.jboss.jca.adapters.jdbc.jdk6.WrappedPreparedStatementJDK6无法转换为OraclePreparedStatement [英] ClassCastException: org.jboss.jca.adapters.jdbc.jdk6.WrappedPreparedStatementJDK6 cannot be cast to OraclePreparedStatement

问题描述

我正在将应用程序从Oracle Application Server迁移到JBoss EAP 6.1.我的大部分工作都在工作，但是我遇到了一个我无法弄清的错误:

I'm working to migrate an application from Oracle Application Server to JBoss EAP 6.1. I have most things working but I am getting one error that I haven't been able to figure out:

13:27:29,743 ERROR [com.myproj.db.dao.myDao] (Thread-164) Get Prepared Statement: 
java.lang.ClassCastException: 
org.jboss.jca.adapters.jdbc.jdk6.WrappedPreparedStatementJDK6 cannot be cast
to oracle.jdbc.internal.OraclePreparedStatement

我在JBoss中将Oracle设置为模块，用于使用ojdbc6.jar进行连接池(并且适用于应用程序的其他部分)，但是对于使用OraclePreparedStatement的应用程序的一部分，它将获得错误.

I have Oracle set up as a module in JBoss for connection pooling using ojdbc6.jar (and it works for other parts of the application), but for the one part of the application that uses an OraclePreparedStatement, it gets the error.

我确实确定WAR文件中没有ojdbc6.jar文件. JBoss中唯一的一个似乎在模块内部.

I did make certain that there is no ojdbc6.jar file in the WAR file. The only one in JBoss seems to be inside of the module.

我确实尝试将OraclePreparedStatement类更改为oracle.jdbc.OraclePreparedStatement，但是结果是相同的.

I did try changing the OraclePreparedStatement class to oracle.jdbc.OraclePreparedStatement, but the results are the same.

我确实尝试在TRACE上运行以进行日志记录，以查看从何处加载类. OraclePreparedStatement是从模块加载的，但以下行除外:

I did try running with TRACE on for logging to see where classes were loading from. OraclePreparedStatement was loaded from the module with the exception of this line:

4:31:40,583 TRACE [org.jboss.modules] (Thread-84) Finding class 
oracle.jdbc.OraclePreparedStatement from Module "deployment.myProj.war:main" from
Service Module Loader

这是日志摘录的链接-基本上只是与OraclePreparedStatement有关的行.

Here's a link to an excerpt of the log - basically just the lines related to OraclePreparedStatement.

我已经确认WAR文件中没有ojdbc6.jar(或任何与Oracle相关的jars)，并且WAR文件中也没有OraclePreparedStatement类.

I have confirmed that there is no ojdbc6.jar (or any Oracle related jars) in the WAR file, and there is no OraclePreparedStatement class inside of the WAR file either.

我确实在我的JBoss部署结构xml文件中将模块列为依赖项.

I do have the module listed as a dependency in my JBoss deployment structure xml file.

有人有什么主意吗?

推荐答案

通过查看javadoc，我猜想org.jboss.jca.adapters.jdbc.jdk6.WrappedPreparedStatementJDK6正在包装底层的Oracle JDBC驱动程序.

From looking at the javadoc I would guess that org.jboss.jca.adapters.jdbc.jdk6.WrappedPreparedStatementJDK6 is wrapping the underlying Oracle JDBC driver.

org.jboss.jca.adapters.jdbc.jdk6.WrappedPreparedStatementJDK6具有获取基础语句的方法.也许您应该尝试如下操作:

org.jboss.jca.adapters.jdbc.jdk6.WrappedPreparedStatementJDK6 has a method to get the underlying statement. Perhaps you should try something like the following:

WrappedPreparedStatementJDK6 statement = ...
OraclePreparedStatement oracleStatement = (OraclePreparedStatement)statement.getUnderlyingStatement();
