problems configuring transaction manager for taskletStep

[techy_bolek]

Hello, essentially I'm trying to run an example from http://java.dzone.com/news/spring-batch-hello-world-1 which is a little dated and was probably written for an older version of spring but I believe it should still be valid. I have a tasklet definition:

<bean id="taskletStep" abstract="true"
class="org.springframework.batch.core.step.tasklet .TaskletStep">
<property name="jobRepository" ref="jobRepository"/>
</bean>


When I run the program I get an error:
Error creating bean with name 'taskletStep$child#1bfa3d3' defined in class path resource [simpleJob.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: TransactionManager is mandatory.

The problem is that I don't have any valid transaction manager bean (i.e. implementing the org.springframework.transaction.PlatformTransactio nManager interface) defined anywhere because this simple test program that does not perform any database access. How do I resolve this? Is there an "empty" or "default" or "dummy" transaction manager implementation I could use?

you could go with the http://static.springsource.org/sprin...moryRepository (ResourcelessTransactionManager is mentioned there too)

or you could configure a in-memory database with e.g. HSQLDB

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="org.hsqldb.jdbcDriver" />
        <property name="url" value="jdbc:hsqldb:mem:testdb" />
        <property name="username" value="sa" />
        <property name="password" value="" />
    </bean>

    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <jdbc:initialize-database data-source="dataSource">
        <jdbc:script location="org/springframework/batch/core/schema-hsqldb.sql"/>
    </jdbc:initialize-database>

needed dependencies

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>${2.5.6.RELEASE or 3.0.5.RELEASE}</version>
        </dependency>
        <dependency>
            <groupId>commons-dbcp</groupId>
            <artifactId>commons-dbcp</artifactId>
            <version>1.4</version>
        </dependency>
        <dependency>
            <groupId>org.hsqldb</groupId>
            <artifactId>hsqldb</artifactId>
            <version>2.2.4</version>
        </dependency>

Thanks. Actually I ended up writing my own transaction manager stub which turned out easier than I thought. Seems to be working...

public class StubTransactionManager implements PlatformTransactionManager {

public void commit(TransactionStatus arg0) throws TransactionException {
}

public TransactionStatus getTransaction(TransactionDefinition arg0)
throws TransactionException {
return new SimpleTransactionStatus();
}

public void rollback(TransactionStatus arg0) throws TransactionException {
}

}
