Hi,
I tested ObjectDB embedded and it is really fast! Everything worked out of the box.
Maven:
<dependency> <groupId>com.objectdb</groupId> <artifactId>objectdb</artifactId> <version>2.4.3</version> </dependency>
Persistence.xml
<persistence-unit name="TEST" transaction-type="RESOURCE_LOCAL"> <provider>com.objectdb.jpa.Provider</provider> <properties> <property name="javax.persistence.jdbc.url" value="$objectdb/db/guests.odb"/> <property name="javax.persistence.jdbc.user" value="admin"/> <property name="javax.persistence.jdbc.password" value="admin"/> </properties> </persistence-unit>
My goal now is to realize same thing using a client version. I started the server on port 6136. Did not figured out how to create an empty db!
Then I updated persistence.xml like: (test.odb doesn't exist)
<persistence-unit name="BikeShop" transaction-type="RESOURCE_LOCAL"> <provider>com.objectdb.jpa.Provider</provider> <properties> <!--<property name="javax.persistence.jdbc.url" value="$objectdb/db/guests.odb"/>--> <property name="javax.persistence.jdbc.url" value="objectdb://localhost:6136/test.odb"/> <property name="javax.persistence.jdbc.user" value="admin"/> <property name="javax.persistence.jdbc.password" value="admin"/> </properties> </persistence-unit>
When I run this I have exception on screen. How come I have class not found exception in embeded server but I do have in c/s? (sorry for long post):
