Question

I am trying to run the the Spring security web application , but when web-app is being deployed I am getting below exception:

o.s.b.f.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/baeldung/spring/TestDbConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]: Factory method 'entityManagerFactory' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/baeldung/spring/TestDbConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.IllegalStateException: Driver for test database type [H2] is not available in the classpath

While i already added below in pom.xml

        <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
            <version>1.4.192</version>
        </dependency>

So this jar also available in classpath, but still getting above exception .

Can someone tell what am I doing wrong?

Answer 1

Here is the solution which worked in my case i made following changes in pom.xml file i have to add <scope> with h2 dependency

<dependency>
    <groupId>com.h2database</groupId>
    <artifactId>h2</artifactId>
    <version>1.4.192</version>
    <scope>runtime</scope>
</dependency>

This scope is used to limit the transitivity of a dependency, and also to affect the classpath used for various build tasks.

runtime scope

This scope indicates that the dependency is not required for compilation, but is for execution. It is in the runtime and test classpaths, but not the compile classpath.
