MyBatis 3.0.5 and mappers loading problem

[raid3n]

I'm using MyBatis 3.0.5 and I have problems about the loading of
mappers as resources. I'm on Windows 7 64, I use Eclipse Indigo 64bit
and jdk7 64. MyBatis is initialized in a Grizzly Web Container (where
are implemented rest services with jersey framework) standalone
instance.

<mappers>
<mapper
url="file:///C:/Users/andrea/workspace/soap2rest/src/main/
java/com/izs/mybatis/FormMapper.xml" />
<mapper resource="src/main/java/com/izs/mybatis/
FormMapper.xml" />
</mappers>


I have the same mappers only for testing, the first is loaded, the
second doesn't work.


Errors:

org.apache.ibatis.exceptions.PersistenceException:
### Error building SqlSession.
### The error may exist in src/main/java/com/izs/mybatis/

Sorry for my english.

Try <mapper resource="com/izs/mybatis/FormMapper.xml"/>
MyBaits loads resources from the classpath.

It seems the resources cannot be seen on the classpath.
You can check by calling Class.getResource("/com/izs/mybatis/FormMapper.xml");

You can try <mapper resource="/com/izs/mybatis/FormMapper.xml"/>

This works fine:
this.getClass().getResource("com/izs/mybatis/FormMapper.xml");

If I write <mapper resource="com/izs/mybatis/FormMapper.xml" /> in the
Configuration.xml the errors are showed after a while. Instead if I
put another path the errors are showed immediately.

Sorry.

So I think I've problem with my classpath settings. It's a Maven
Project.
I'm trying:

in these cases url is null:
URL url = this.getClass().getResource("src/main/java/com/izs/mybatis/
FormMapper.xml");
URL url = this.getClass().getResource("/src/main/java/com/izs/mybatis/
FormMapper.xml");
URL url = this.getClass().getResource("com/izs/mybatis/
FormMapper.xml");
URL url = this.getClass().getResource("/com/izs/mybatis/
FormMapper.xml");

[raid3n]

My .classpath file:

<classpath>
<classpathentry kind="src" path="src/main/java" including="**/
*.java"/>
...
</classpath>

[raid3n]

Sorry for my flood:

URL ur = Thread.currentThread().getContextClassLoader()
.getResource("src/main/java/com/izs/mybatis/FormMapper.xml");

It's not null. Why?

If you are using maven, your mapper and config files should be put under the src/main/resources, not src/main/java. The package goal would then include them in the jar or war file you build. You would then reference them using the package path only(ie "java/com/izs/mybatis/FormMapper.xml")
If the files are for testing, then they would be put under src/test/resources
