我正在使用 comporsys JCA 连接器从 Java 连接到大型机环境。Java 应用程序部署在 JBOSS 中。以这种方式配置的连接器：

<connection-factories>
    <no-tx-connection-factory>
        <jndi-name>ComporsysIMSConnector</jndi-name>
        <rar-name>ims_connector_port4027_CreditAuth.rar</rar-name>
        <connection-definition>de.comporsys.connector.ims.ConnectionFactory</connection-definition>
        <min-pool-size>1</min-pool-size>
        <max-pool-size>15</max-pool-size>
        <shrinking-enabled>true</shrinking-enabled>
        <shrink-period-minutes>2</shrink-period-minutes>
        <logging-enabled>true</logging-enabled>
        <!-- <log-filename>/opt/jboss/xxxx/logs/ims_connector.log</log-filename> -->
        <log-filename>D:\ims_connector.log</log-filename>
    </no-tx-connection-factory>
</connection-factories>

通信不能 100% 正常，因为我在日志中看到很多错误，如下所示：

[2010-12-16 05:21:10,061] WARN  (org.jboss.resource.connectionmanager.NoTxConnectionManager:738) - Pearl 1,DE82000,CGN,D5 ,10450565,768209411 - Connection error occured: org.jboss.resource.connectionmanager.NoTxConnectionManager$NoTxConnectionEventListener@3dcbef2a[state=NORMAL mc=de.comporsys.connector.ims.ManagedConnectionImpl@4743f21b handles=1 lastUse=1292++++++++++++ permit=true trackByTx=false mcp=org.jboss.resource.connectionmanager.JBossManagedConnectionPool$OnePool@7afdd15b context=org.jboss.resource.connectionmanager.InternalManagedConnectionPool@2dbbec72]

不幸的是，我没有任何信息，因为 composys 不再支持它是什么意思。你知道为什么会这样吗？

有一个 IMSConnectionFactory 初始化 comporsys 的东西

 public static ConnectionFactory getIMSConnectionFactory() {
        InitialContext context;
        ConnectionFactory imsConnectionFactory = null;

        try {
            // Create a Properties Object and set the JNDI properties
            Properties jndiProperties = new Properties();

            jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, WizardContext.getInstance().getWizardProperties().getJndiClass());

            // Try obtaining a JNDI context so that the application server can be queried
            context = new InitialContext(jndiProperties);

            // Request the Connection Factory from the application server using a JNDI context lookup 
            imsConnectionFactory = (ConnectionFactory) context.lookup(WizardContext.getInstance().getWizardProperties().getConnectionJndi());

事务处理可能在 m_IMSStatementSync.execute 中，但它是一个黑匣子，因为它是第三方的东西。IMSConnector 在 JBOSS 中注册，我们在 servlet 中访问它。事务处理程序的详细信息：

for (int 尝试 = 1 + 坚韧；尝试 > 0;) { 尝试 {

                    // Slightly nervous re. the location of this block.
                    // It looks like it should be above, where it is now commented out,
                    // but moving it there coincided with failures.
                    // This may well have just been a coincidence - but it all happened at cutover time,
                    // so for the sake of safety I've put it back here for now.
                    m_IMSStatementSync = m_IMSConnection.createStatement(); /* This created by the connection factory */
                    m_IMSRequest = m_IMSStatementSync.createRequest();
                    m_IMSRequest.setTimeout(m_WizardConfiguration.getWizardTimeOut());
                    m_IMSRequest.setTransaction(p_Input.get_TransactionCode());
                    m_IMSRequest.setCommArea(p_Input);
                    m_IMSRequest.setLterm(p_Input.get_TSR().get_ID());
                    m_IMSRequest.setTimer((byte) WizardOperationConstants.IMS_CONNECT_SYNC_TIMEOUT);
                    // end of block

                    // Execute the IMS transaction
                    m_IMSReply = m_IMSStatementSync.execute(m_IMSRequest);      /*pac7102*/

                    attempts = 0;
                }
                catch (NoActiveTransactionException e) {

                    if (--attempts < 1) {
                        tenaciousness >>= 1;
                        throw (e);
                    }
                    try {
                        wait(rnd());
                    }
                    catch (InterruptedException f) { ... }

                }

从堆栈跟踪中可以看出警告的原因：

de.comporsys.connector.NoActiveTransactionException: connection is not in transaction

....但您肯定想澄清界面是否实际工作。无论如何，连接不在事务中的警告是因为您将 JCA 池定义为非事务池。为了切换到事务池，它应该看起来像这样：

<connection-factories>
    <tx-connection-factory>
        <jndi-name>ComporsysIMSConnector</jndi-name>
        <rar-name>ims_connector_port4027_CreditAuth.rar</rar-name>
        <connection-definition>de.comporsys.connector.ims.ConnectionFactory</connection-definition>
        <min-pool-size>1</min-pool-size>
        <max-pool-size>15</max-pool-size>
        <shrinking-enabled>true</shrinking-enabled>
        <shrink-period-minutes>2</shrink-period-minutes>
        <logging-enabled>true</logging-enabled>
        <!-- <log-filename>/opt/jboss/xxxx/logs/ims_connector.log</log-filename> -->
        <log-filename>D:\ims_connector.log</log-filename>
    </tx-connection-factory>
</connection-factories>

我假设仅支持此功能，因为警告消息表明它希望连接处于事务中，这就是tx-connection-factory将执行的操作。

我会试一试，看看会发生什么。

From what location are you initiating the call to your JCA resource?

In other words, what is

 at com.xxx.ims.access.GenericImsTransaction.executeUCIAysnc(GenericImsTransaction.java:340)

?

From the stack trace it seems clear that there is no EJB involved here. The call comes in from a Servlet and then propagates to your own code until the JCA connection is being used.

GenericImsTransaction sounds like it does something transactional, but what exactly? You should verify that there is a JTA transaction being started somewhere. In your Servlet you can get a hold of a UserTransaction, which is a simple interface to start and commit JTA transactions:

@Resource 
private UserTransaction tx;

If you're using a pre-Java EE 5 version of JBoss AS, then you can use the following code to obtain a UserTransaction:

private UserTransaction getUserTransaction() {
    UserTransaction tx = null;

    try {
        tx = (UserTransaction)new InitialContext().lookup("java:comp/UserTransaction");
    } catch (NamingException e) {
        throw new RuntimeException("No UserTransaction available at default location, is a transaction manager installed?", e);
    }

    return tx;
}

Somewhere in your callstack, you then need to call tx.begin(); and afterwards tx.commit() or tx.rollback().

If you're able to use EJB3, then it's easier to let your Servlet call a stateless session bean (@Stateless) and then let this bean call your other code. You will then automatically have a transaction and the container will take care of committing or rolling it back. If you're not yet using EJBs it may be difficult to retrofit the existing code into using them and the manual JTA code may be easier to insert.

事务连接工厂声明是必要的，但还不够。

您还需要向与数据库交互的方法添加声明性事务。我会推荐“PROPAGATION=REQUIRED_NEW”。
