Body
A commonly used strategy is to define all runtime configurations in one or several *.properties files and use spring's PropertyPlaceholderConfigurer to load the values and substitute the placeholder in applicationContext.xml, read more here: <a href="https://stackoverflow.com/questions/13297157/best-ways-to-deal-with-properties-values-in-xml-file-in-spring-maven-and-eclips/13297686#13297686">Best ways to deal with properties values in XML file in Spring, Maven and Eclipses</a>. app.properties: <pre><code># Dadabase connection settings: hibernate.connection.driver_class=org.hsqldb.jdbcDriver hibernate.connection.url=jdbc:hsqldb:file:~/something-db/somethingdb hibernate.connection.username=sa hibernate.connection.password=changeit hibernate.dialect=org.hibernate.dialect.HSQLDialect hbm2ddl.auto=update ... ... </code></pre> applicationContext-dataStore.xml: <pre><code><bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list>  <value>classpath:app.properties</value>  <value>file:///opt/my-app/conf/app.properties</value> </list> </property> <property name="ignoreResourceNotFound" value="true"/> </bean> ... ... <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${hibernate.connection.driver_class}" /> <property name="url" value="${hibernate.connection.url}" /> <property name="username" value="${hibernate.connection.username}" /> <property name="password" value="${hibernate.connection.password}" /> </bean> </code></pre> One problem here is the PropertyPlaceholderConfigurer doesn't parse persistence.xml, the solution is to move all hibernate configuration into Spring's applicationContext.xml, as it is not necessary to set them in persistence.xml. read more here: <a href="https://stackoverflow.com/questions/1834954/loading-properties-in-spring-context-xml-and-persistence-xml/3979832#3979832">loading .properties in spring-context.xml and persistence.xml</a>. persistence.xml: <pre><code><?xml version="1.0" encoding="UTF-8"?> <persistence 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" version="1.0"> <persistence-unit name="JPAService" transaction-type="RESOURCE_LOCAL"/> </persistence> </code></pre> applicationContext-datSource.xml: <pre><code><bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${hibernate.connection.driver_class}"/> <property name="url" value="${hibernate.connection.url}"/> <property name="username" value="${hibernate.connection.username}"/> <property name="password" value="${hibernate.connection.password}"/> </bean> ... ... <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"> <property name="persistenceXmlLocation" value="classpath:./META-INF/persistence.xml"/> <property name="persistenceUnitName" value="JPAService"/> <property name="dataSource" ref="dataSource"/> <property name="jpaVendorAdapter"> <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"> <property name="databasePlatform" value="${hibernate.dialect}"/> <property name="showSql" value="true" /> <property name="generateDdl" value="true"/> </bean> </property> <property name="jpaProperties">  <props> <prop key="hibernate.hbm2ddl.auto">${hbm2ddl.auto}</prop> </props> </property> </bean> </code></pre> Note that the web application need to be restarted every time you alter the configuration in /opt/my-app/conf/app.properties, in order to make changes take effect.

1. COyorkw, thank you for that detailed reply. But if I understand you correct, I can't change hibernate.connection.url on the fly using your solution? I actually need to change this on the fly, so a user can use e.g. file - open and then select a file which includes a HSQL database. Do you have any hint on this? Thanks :-)

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
