Question

我正在使用Spring-Hibernate-Websphere应用程序和sybase作为数据库。以下是配置Spring / Hibernate以引用Websphere的JNDI数据源的代码片段。

    <?xml version="1.0" encoding="UTF-8"?>
    <beans  xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:tx="http://www.springframework.org/schema/tx"

    xsi:schemaLocation="

        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">


<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
    <property name="jndiName" value="java:comp/env/jdbc/icpDS" />
    <property name="lookupOnStartup" value="false" />
    <property name="cache" value="true" />
    <property name="proxyInterface" value="javax.sql.DataSource" />
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="packagesToScan" value="com.ubs.research.icp.hibernate.object" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">${hibernate.dialect}</prop>
            <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
            <prop key="hibernate.max_fetch_depth">${hibernate.max_fetch_depth}</prop>
        </props>
    </property>
</bean>
<tx:annotation-driven />
<bean id="transactionManager" class="org.springframework.transaction.jta.WebSphereUowTransactionManager"/>

以下是上述代码中使用的属性的值：

hibernate.dialect=org.hibernate.dialect.SybaseDialect
hibernate.show_sql=true
hibernate.format_sql=true
hibernate.connection.autocommit=false
hibernate.max_fetch_depth=0

上面的配置在使用一些简单的查询时工作正常，我可以在控制台上看到那些hibernate生成的查询。但是，在执行一些复杂查询（具有多个连接）时，我发现由以下异常引发的异常。

可能导致此错误的原因是什么？任何指针都非常感激。

通过安装Websphere Fixpack 7.0.0.13+（我们安装了7.0.0.21）解决了这个问题。问题在于从websphere处理getUpdateCount（）。当创建预准备语句时（在我们的例子中是Hibernate），并且在执行之前，如果调用了getUpdateCount（），则Syabase（以及根据IBM支持的informix）抛出SQLException，而其他数据库只返回-1。这不是从Websphere处理的，并且exeception被传播到应用程序代码。使用fixpack，可以解决问题并解决问题。
