Glassfish Eclipselink an Hibernate

[Marcus Didius Falco]

I am using Glassfish v3 with Apache Derby 10.6.1 (Network Server Mode)
I am trying to deploy a sample web application (Beginnig Java EE 6 platform with Glassfish3, chapter 10) with EJBs and Entities.

persistence.xml:

  
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence">
    <persistence-unit name="book" transaction-type="JTA">
        <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
        <class>entities.Book</class>
        <properties>
            <property name="eclipselink.target-database" value="DERBY"/>
            <property name="eclipselink.jdbc.driver" value="org.apache.derby.jdbc.ClientDriver"/>
            <property name="eclipselink.jdbc.url" value="jdbc:derby://localhost:1527/books;create=true"/>
            <!--<property name="eclipselink.jdbc.driver" value="org.apache.derby.jdbc.EmbeddedDriver"/>-->
            <!--<property name="eclipselink.jdbc.url" value="jdbc:derby:chapter10DB;create=true"/>-->
            <property name="eclipselink.jdbc.user" value="APP"/>
            <property name="eclipselink.jdbc.password" value="APP"/>
            <!--property name="eclipselink.ddl-generation" value="update"/-->
            <property name="eclipselink.ddl-generation" value="drop-and-create-tables"/>
            <property name="eclipselink.logging.level" value="INFO"/>
        </properties>
    </persistence-unit>
</persistence>       

  

During deployment I get the exception:

Deployment encountered SQL Exceptions:
Got SQLException executing statement "CREATE TABLE SEQUENCE (SEQ_NAME VA
RCHAR(50) NOT NULL, SEQ_COUNT DECIMAL(15), PRIMARY KEY (SEQ_NAME))": java.sql.SQ
LException: Table/View 'SEQUENCE' ist bereits in Schema 'APP' vorhanden.

(translation of the German part: 'SEQUENCE' exists already in Schema 'App'

the application gets deployed anyway.

after that I cannot connect with ij:
connect 'jdbc:derby://localhost:1527/book'

ij says the database does not exist.

What do I have to do to avoid the SQL command?

And is there a way to find out which databases a present in Derby?

The SEQUENCE table error is just a warning, you can ignore it as you are replacing existing tables.
The reason the SEQUENCE table is not replaced is that there may be other tables using it and we do not want to reset their sequence values.

For the URL note you used books, not book,
use,
jdbc:derby://localhost:1527/books

Weird. I posted an answer, but then James's answer from an hour earlier showed up.
