Java e JDBC: É possível via JPA Persistence se conectar com banco de dados DB2?

Oi Rafael

Especificamente para o db2 nunca tive que fazer essa conexão, mas é para ser possível sim. Você está tendo algum problema?

Sim, preenchi o persistence.xml do mesmo jeito que estava conectando com sucesso para o mySql.

<persistence-unit name="CRDDB001">

       <provider>org.hibernate.ejb.HibernatePersistence</provider>

    <class>br.gov.caixa.sicrd.model.Crdtbc02</class>
    <class>br.gov.caixa.sicrd.model.Crdtbc08</class>

    <properties>
    <!--<property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
        <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/crd?autoReconnect=true" />
        <property name="javax.persistence.jdbc.user" value="root" />
        <property name="javax.persistence.jdbc.password" value="@Maranata01" />

        <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" /> -->

        <property name="javax.persistence.jdbc.driver" value="com.ibm.db2.jcc.DB2Driver" />
        <property name="javax.persistence.jdbc.url" value="jdbc:db2://url?autoReconnect=true" />
        <property name="javax.persistence.jdbc.user" value="user" />

        <property name="hibernate.dialect" value="org.hibernate.dialect.DB2Dialect" />
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.format_sql" value="true"/>

    </properties>
</persistence-unit>

Esse é o erro
