I am working on Spring-Hibernate-Websphere application and sybase as database. Following is the code snippet to configure Spring/Hibernate to refer to JNDI datasource of Websphere. 

    <?xml version="1.0" encoding="UTF-8"?>
    <beans  xmlns="http://www.springframework.org/schema/beans"

<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.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"/>

Here are the values for the properties used in above code:

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

Above configuration works fine while using some simple queries, and I can see those hibernate generated queries on console. However, while executing some complex queries (with multiple joins), I find exception cased by below exception.

What may be causing this error? Any pointers greatly appreciated.

    The problem was resolved with the installation of the Websphere Fixpack 7.0.0.13+ (We installed 7.0.0.21). The problem lied in handling of the getUpdateCount() from websphere. When a prepared statement is created (in our case by Hibernate), and before execution, if getUpdateCount() is called, Syabase (and informix as per IBM support), throws SQLException while other databases simply return -1. This was not handled from Websphere and the exeception was propogated to the application code. With the fixpack, this is handled and problem is resolved.
