Spring + Tomcat: Setup relative file path

Question

I am deploying Spring 3 app on Tomcat7. I am using OXM unmarshaller so I need to create StreamSource like this:

unmarshaller.unmarshal(new StreamSource(new FileInputStream(dbSetupPath)))

I set value for dbSetupPath like this and it works in unit tests:

@Value("src/main/resources/db-setup.xml")
String dbSetupPath;

When I deploy on Tomcat though, I am getting FileNotFoundException. What is correct path that'll keep my tests passing and Tomcat working? I am deploying exploded:war atm.

Answer 1

When you deploy on tomcat, all your resources folder files goes into .war file in WEB-INF/classes folder.

you need to try

@Value("classpath:/db-setup.xml")

So tomcat will check db-setup.xml in the classpath

Answer 2

Place your db-setup.xml likes the same as picture

and change this

@Value("db-setup.xml")
String dbSetupPath;

Answer 3

I think you can specify path like that one:

${webAppRoot}WEB-INF/db-setup.xml

and put db-setup.xml into WEB-INF folder (or create some subfolder).

Also for correct work of this approach you need to specify in your web.xml such parameter:

<context-param>
    <param-name>webAppRootKey</param-name>
    <param-value>webAppRoot</param-value>
</context-param>

Spring will automatically inject to this parameter actual path to your web app root folder.

This is working in my case for logging that's why I think it will work in your case too.

Here is discussion about webAppRootKey

So my solution was to inject the value to the org.springframework.core.io.Resource instead of the plain String like this:

@Value("classpath:/db/db-setup.xml")
Resource dbConfig;

And then I accessed the underlying file and supplied it to the marshaller:

unmarshaller.unmarshal(new StreamSource(dbConfig.getFile());
