我正在尝试使用Oracle AQ支持XA事务，因为我有其他数据源，如Active MQ和DB参与事务。当我试图发布到oracle aq queue1。从数据源获取XAconnection时失败并出现NullPointerException。
我使用的是oracle ojdbc6，11.2版本的aqapi.jar 我的骆驼蓝图与我的豆类定义的片段在下面给出

您能否帮我确定问题所在。例外是l

我想我得到了问题所在。我从oracle 11.2客户端使用的aqapi.jar有bug。类AqjmsGeneralDBConnection没有为QAConnection初始化m_dbConn对象（使用XAConnection作为参数的构造函数）并尝试访问m_dbConn对象上的getURL（），该对象为null。我尝试使用10.2.0版本的aqapi13.jar，它可以正常工作
AQjmsGeneralDBConnection(AQjmsDBConnMgr paramAQjmsDBConnMgr, Connection paramConnection, boolean paramBoolean1, boolean paramBoolean2)
throws JMSException
{
this.m_connMgr = paramAQjmsDBConnMgr;
this.m_dbConn = paramConnection;
this.m_isExternal = paramBoolean1;
this.m_force = paramBoolean2;
this.providerKey = getProviderKey();
}
AQjmsGeneralDBConnection(AQjmsDBConnMgr paramAQjmsDBConnMgr, XAConnection paramXAConnection, boolean paramBoolean1, boolean paramBoolean2)
throws JMSException
{
this.m_connMgr = paramAQjmsDBConnMgr;
this.m_xaConn = paramXAConnection;
this.m_isExternal = paramBoolean1;
this.m_force = paramBoolean2;
this.providerKey = getProviderKey();
}
private String getProviderKey()
throws JMSException
{
try
{
OracleConnection localOracleConnection = (OracleConnection)this.m_dbConn;
**String str1 = localOracleConnection.getURL();**
int i = str1.indexOf('@');
String str2;
if (i < 0)
{
if ((!"jdbc:oracle:kprb:".equals(str1)) && (!"jdbc:default:connection:".equals(str1))) {
AQjmsError.throwEx(112);
}
str2 = "jdbc:oracle:kprb:";
}
else
{
str2 = str1.substring(i);
}
return str2.toUpperCase();
}
catch (SQLException localSQLException)
{
throw new AQjmsException(localSQLException);
}
}
