Java – hibernate5 hhh000181: no suitable connection provider is encountered, assuming that the application will provide a connection
•
Java
I haven't written any code yet. I'm just trying to run MVN hibernate 5-ddl: Gen DDL to convert an existing class to DDL
What might cause the warning connectionproviderinitiator – hhh000181: no suitable connection provider was encountered, assuming that the application will provide a connection?
This is my persistence xml
<persistence> <persistence-unit name="manager1" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider> <properties> <property name="hibernate.ejb.cfgfile" value="/hibernate.cfg.xml"/> </properties> </persistence-unit> </persistence>
And hibernate cfg. xml:
<?xml version='1.0' encoding='utf-8'?> <!DOCTYPE hibernate-config PUBLIC "-//Hibernate/Hibernate Config DTD 3.1//EN" "http://www.hibernate.org/dtd/hibernate-config-3.1.dtd"> <hibernate-config> <session-factory> <!-- Database connection settings --> <property name="connection.driver_class">org.apache.derby.jdbc.EmbeddedDriver</property> <property name="connection.url">jdbc:derby:eTrade;create=true</property> <property name="connection_userid">root</property> <property name="connection_pwd">root</property> <!-- JDBC connection pool (use the built-in) --> <property name="connection_pool_size">true</property> <property name="dialect">org.hibernate.DerbyDialect</property> <!-- Disable the second-level cache --> <property name="cache.provider_class">org.hibernate.NoCacheProvider</property> <!-- Echo all executed sql to stdout --> <property name="show_sql">1</property> <!-- Drop and re-create the database schema on startup --> <property name="hbmdl.auto">update</property> <!-- Names the annotated entity class --> <mapping class="com.eTrade.etws.market.OptionChainPair" /> </session-factory> </hibernate-configuration>
And POM Bottom of XML:
<build> <plugins> <plugin> <groupId>de.jpdigital</groupId> <artifactId>hibernate5-ddl-maven-plugin</artifactId> <version>1.0.1-hibernate-5.2.4.Final</version> <configuration> <dialects> <param>DERBY_10_7</param> </dialects> <packages> <param>com.eTrade.etws.market</param> </packages> </configuration> </plugin> </plugins> </build>
This is the last few lines of console output I chose to focus only on the first warning now

Solution
You may have found a way to solve it, but you can try this I had a similar problem that took me some time, and then I found that I missed an important statement in the configuration
Configuration cfg = new Configuration() .**setProperties(database)** .addPackage("com.demo.pojo") .addAnnotatedClass(User.class) .addAnnotatedClass(Products.class);
