我有这个类为WSCallHelper.jdbcCall实施是8
package com.middleware.jdbc.j2ee.websphere;
public class WS50NativeJDBCExtractorImpl implements NativeJDBCExtractorInf {
private Class webSphere5ConnectionClass;
private Method webSphere5NativeConnectionMethod;
private Class webSphere5StatementClass;
private Method webSphere5NativeStatementMethod;
public WS50NativeJDBCExtractorImpl() throws Exception {
try {
this.webSphere5ConnectionClass = getClass().getClassLoader().loadClass("com.ibm.ws.rsadapter.jdbc.WSJdbcConnection");
Class jdbcAdapterUtilClass = getClass().getClassLoader().loadClass("com.ibm.ws.rsadapter.jdbc.WSJdbcUtil");
this.webSphere5NativeConnectionMethod = jdbcAdapterUtilClass.getMethod("getNativeConnection", new Class[] { this.webSphere5ConnectionClass });
this.webSphere5StatementClass = getClass().getClassLoader().loadClass("com.ibm.ws.rsadapter.jdbc.WSJdbcStatement");
this.webSphere5NativeStatementMethod = webSphere5StatementClass.getDeclaredMethod("getJDBCImplObject", null);
this.webSphere5NativeStatementMethod.setAccessible(true);
} catch (Exception ex) {
e.printStackTrace();
}
}
public Connection getConnection(Connection c) throws Exception {
if (this.webSphere5ConnectionClass != null && this.webSphere5ConnectionClass.isAssignableFrom(c.getClass())) {
try {
return (Connection) this.webSphere5NativeConnectionMethod.invoke(null, new Object[] { c });
} catch (Throwable e) {
e.printStackTrace();
}
} else {
return c;
}
}
private Object primGetStatement(Statement stmt) throws Exception {
if (this.webSphere5StatementClass != null && this.webSphere5StatementClass.isAssignableFrom(stmt.getClass())) {
try {
return this.webSphere5NativeStatementMethod.invoke(stmt, null);
} catch (Throwable e) {
e.printStackTrace();
}
} else {
return stmt;
}
}
public CallableStatement getCallableStatement(CallableStatement cs) throws Exception {
return (CallableStatement) primGetStatement(cs);
}}
我想用WSCallHelper.jdbcCall作为为8信息中心建议,但我不能够得到它正确的。我试过
Object st = WSCallHelper.jdbcCall(null, this.webSphere5StatementClass, "getJDBCImplObject", new Object[]{}, new Class[]{});
我得到了NOT_A_JDBC_OBJECT错误。当我没有使用WSCallHelper,我越来越
java.lang.ClassCastException: oracle.jdbc.driver.OracleCallableStatementWrapper incompatible with oracle.jdbc.OracleCallableStatement
我还试图用
CallableStatement cStmt = getCallableStatement(call);
if(stmt.isWrapperFor(OracleCallableStatement.class)){
OracleCallableStatement ocs = (OracleCallableStatement) stmt;
}
(其中调用变量的SQL语句)。它说stmt没有被包装。
我正在使用上面的类连接到Oracle 9i数据库。任何人都知道如何使用WSCallHelper.jdbcCall来获取上面的代码?谢谢。
我认为'WSJdbcUtil'中的方法已被弃用。我正在尝试'com.ibm.websphere.rsadapter.WSCallHelper.getNativeConnection()'。 – FrustratedWithFormsDesigner 2014-01-14 23:18:58
