entity ref includes in spring beans xml

[dscherger]

We're trying to sort out how to deploy to various environments that need slightly different configurations in spring-beans.xml (i.e. local jdbc verses jndi datasources etc.). Initially I thought that entity ref style includes would be good, but they don't seem to work.

I have the following in my spring beans xml:

<!DOCTYPE beans PUBLIC "..." "..." [
<!ENTITY datasource SYSTEM "datasource.xml">
]>

...
&datasource;
...

For junit tests we use:

context = new ClassPathApplicationContext("spring-beans.xml")

And the entity ref fails with

org.xml.sax.SAXParseException: Relative URI "datasource.xml"; can not be resolved without a base URI.

Which is because in the context construction there is no scheme (i.e. "file:///..."). The location of things is different on various machines and absolute references are not going to work. Is there some other way to set the base URI?

Any ideas on a good way to deal with this would be appreciated.

Presumably it's a fairly common problem (multiple configurations for different environments like development, cruisecontrol, testing, qa, production, etc.)

Thanks,
Derek

how about configuring beans in multiple files and using

String locations[] = {"file1.xml","file2.xml"};
context = new ClassPathApplicationContext(locations);

Hi

Have you tried using the <import/> element that was added in the latest release of Spring?

<beans>
    <import resource="datasource.xml"/>
    <bean>...</bean>
    <bean>...</bean>
</beans>

This should solve your problem (assuming that you can upgrade to the latest version of Spring :wink.

Along those lines, I am using <import/> but need to import an XML files from a different JAR in the classpath. Is this possible?

I have some abstract beans declared in XML files in the frramework JAR and individual projects need to include and subclass.

I tried various forms of

<import resource="cdpUtilities.jar!/HibernateDataSource.xml"/>

with no luck.

For now I have the included file copied into each project. Even worse, I haven't found a cleaner way to import it from subpackages other than

<import resource="../../../../HibernateDataSource.xml"/>

Just "/Hibernate..." didn't work.

Now that I think about it, the only way that's working is when the files are in the build/test/classes directory -- not in a JAR. Can you import from a JAR?
