Cannot locate hibernate mappings files in jar

[rnayani]

We tried configuring the LocalSessionFactoryBean to locate the hibernate mapping files in a jar or directory. Neither seems to work. We get the error:

java.io.FileNotFoundException: class path resource [classpath*:hibernate-mapping] cannot be resolved to URL because it does not exist
at org.springframework.core.io.ClassPathResource.getU RL(ClassPathResource.java:147)
at org.springframework.core.io.ClassPathResource.getF ile(ClassPathResource.java:154)
at org.springframework.orm.hibernate.LocalSessionFact oryBean.afterPropertiesSet(LocalSessionFactoryBean .java:463)

Here's how we tried to configure the sessionfactory:

<property name="mappingJarLocations">
<list>
<value>classpath:hibernate-mappings.jar</value>
</list>
</property>

where hibernate-mappings.jar was in the root of the ear

and we tried:

<property name="mappingDirectoryLocations">
<list>
<value>classpath*:hibernate-mapping</value>
</list>
</property>

where the directory was in the root directory of the ear.

Neither works. I saw in your posting that you got it to work with the directory on the file system. Am I doing something wrong? We also tried giving the absolute path of the directory and jar - that didn't work either.

Can you do that?

I have always kept my mapping files within the WAR and listed them directly. Using classpath:/class.hbm.xml,classpath:/class1.hbm.xml etc.

Are you sure it can load them from a jar? If so you might have to use the special jar notation which is something like (i.e. I can't remember exactly ):

classpath:/myJar!classa.hbm.xml

Just guessing though so don't take this too seriously

Hi
Have you been able to fix this issue?
I am getting the same error.

Thanks

You must place your mapping files in a subdirectory. Do to limitations in the way java handles jar files, unfortunately, it's not possible to do a classpath* search for resources located in the root path of a jar/war etc..

See the comments for PathMatchingResourcePatternResolver.

Oliver's right, but just to make it clear with a sample...
For application contexts in the classpath at:

/com/company/applicationContext.xml
/com/company/applicationContext-ds.xml

If they're in WEB-INF/classes the following will work:
classpath*:**/applicationContext*.xml

If they're in a JAR in WEB-INF/lib (for example) the following will work:
classpath*:/com/**/applicationContext*.xml

For anything in the root of a JAR, you can't use wildcards to load it.
