Question

I have a this war structure:
Some.war

-WEB-INF
–lib
—library.jar
—-some.xsd
—-some2.xsd

And i want to get all xsd files in library.jar, but spring don’t want to search it.

ContextLoaderListener.getCurrentWebApplicationContext()
                     .getResources("classpath*:**/*.xsd")

result is empty. I also tried: classpath:**/*.xsd, **/*.xsd.

How i can get all xsd files in jar using “ant” template (*/.xsd)?

Answer 1

The answer lies in the Spring docs:

4.7.2.3 Other notes relating to wildcards

Please note that “classpath*:” when
combined with Ant-style patterns will
only work reliably with at least one
root directory before the pattern
starts, unless the actual target files
reside in the file system. This means
that a pattern like “classpath*:*.xml”
will not retrieve files from the root
of jar files but rather only from the
root of expanded directories. This
originates from a limitation in the
JDK’s ClassLoader.getResources()
method which only returns file system
locations for a passed-in empty string
(indicating potential roots to
search).
