Hi Thomas, Please make sure that your h2 database is started and required tables are created. You can use the following test as example how to do that (please see, CacheJdbcPojoStoreAbstractSelfTest#beforeTest) https://github.com/apache/ignite/blob/master/modules/core/src/test/java/org/apache/ignite/cache/store/jdbc/CacheJdbcPojoStoreAbstractSelfTest.java
Cache configuration should be modified as well. 1. First of all, correct DB connection URL should be provided. For instance, <bean id="simpleDataSource" class="org.h2.jdbcx.JdbcDataSource"> <property name="URL" value="jdbc:h2:mem:TestDatabase;DB_CLOSE_DELAY=-1"/> <property name="user" value="username"/> <property name="password" value=""/> </bean> 2. secondly, you need to configure types mapping within the cache configuration. Let's assume that you have a simple cache IgniteCache<Integer, String> <bean class="org.apache.ignite.configuration.CacheConfiguration"> <property name="name" value="test-cache"/> <property name="readThrough" value="true"/> <property name="writeThrough" value="true"/> <property name="cacheStoreFactory"> <bean class="org.apache.ignite.cache.store.jdbc.CacheJdbcPojoStoreFactory"> <property name="dataSourceBean" value="storeDataSource"/> <property name="dialect"> <bean class="org.apache.ignite.cache.store.jdbc.dialect.H2Dialect"/> </property> <property name="types"> <list> <bean class="org.apache.ignite.cache.store.jdbc.JdbcType"> <property name="cacheName" value="test-cache"/> <property name="keyType" value="java.lang.Integer"/> <property name="valueType" value="java.lang.String"/> <property name="databaseSchema" value="PUBLIC"/> <property name="databaseTable" value="testtable"/> <property name="keyFields"> <list> <bean class="org.apache.ignite.cache.store.jdbc.JdbcTypeField"> <property name="databaseFieldName" value="ID"/> <property name="databaseFieldType"> <util:constant static-field="java.sql.Types.INTEGER"/> </property> <property name="javaFieldName" value="id"/> <property name="javaFieldType" value="java.lang.Integer"/> </bean> </list> </property> <property name="valueFields"> <list> <bean class="org.apache.ignite.cache.store.jdbc.JdbcTypeField"> <property name="databaseFieldName" value="name"/> <property name="databaseFieldType"> <util:constant static-field="java.sql.Types.VARCHAR"/> </property> <property name="javaFieldName" value="name"/> <property name="javaFieldType" value="java.lang.String"/> </bean> </list> </property> </bean> </list> </property> </bean> </property> </bean> additional example(s) can be found here: https://github.com/apache/ignite/blob/master/modules/spring/src/test/config/jdbc-pojo-store-builtin.xml Thanks, Slava. -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
