java - Hibernate with JPA won't create table -

i want create table using hibernate + jpa. problem whenever run code won't create tables. have created empty database. utilize hibernate + jpa + hsql + maven.

here persistence.xml:

<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

<!-- provider of persistence --> <provider>org.hibernate.ejb.hibernatepersistence</provider> <!-- classes, in jpa-annotations read --> <class>com.mysite.warehousebase.base.productdata</class> <properties> <property name="hibernate.connection.driver_class" value="org.hsqldb.jdbcdriver"/> <property name="hibernate.connection.url" value="jdbc:hsqldb:warehouse"/> <property name="hibernate.dialect" value="org.hibernate.dialect.hsqldialect"/> <property name="hibernate.connection.username" value="sa" /> <property name="hibernate.connection.password" value="" /> <property name="hibernate.show_sql" value="true"/> <property name="hibernate.format_sql" value="true"/> <property name="hibernate.hbm2ddl.auto" value="update"/> </properties>

here productdata.java code:

}

and main.java code:

public static void main(string[] args) { datastructuretest testproduct = new datastructuretest(); testproduct.testproductdata(); }

what wrong? why hibernate won't create table needed? have tried using hibernate.hbm2ddl.auto value of "update". won't help.

can seek

<property name="hibernate.hbm2ddl.auto" value="create"/>

also 'transaction-type="resource_local" defined in persistence xml

java hibernate table jpa
