Re: Data grid client errors out when datasource not defined

[Anton Vinogradov]

Jason,

Thanks for tips,

I found that CacheJdbcPojoStoreFactory required to have bean specified at
 <property name="*dataSourceBean*" value="dataSource"/>
inside client config to use this cache.

Another way is to specify *dataSource *property instead.

for example:

<bean id="storeDataSource"
class="org.apache.ignite.cache.store.jdbc.CacheJdbcPojoStore">
    <property name="dataSource">
        <bean class="org.h2.jdbcx.JdbcConnectionPool" factory-method="create">
            <constructor-arg value="jdbc:h2:tcp://0.0.0.0/mem:db"/>
            <constructor-arg value="sa"/>
            <constructor-arg value=""/>
        </bean>
    </property>
</bean>

Here's the code explaining how it works:

if (dataSrc != null) // Use this case.
    store.setDataSource(dataSrc);
else {
    if (dataSrcBean != null) {
        if (appCtx == null)
            throw new IgniteException("Spring application context
resource is not injected.");

        IgniteSpringHelper spring;

        try {
            spring = IgniteComponentType.SPRING.create(false);

            DataSource data = spring.loadBeanFromAppContext(appCtx,
dataSrcBean);

            store.setDataSource(data);

Let me know in case it will not help.
