Does ibatis 2.x OSGi ready?

Rate this Message:
We found a problem when use ibatis 2.3.4 in spring dm,ibatis can't find sql-map2.dtd,and try to resolve it by network.
By digging the source code(com.ibatis.sqlmap.engine.builder.xml.SqlMapClasspathEntityResolver and com.ibatis.common.resources.Resources),we found ibatis will always find the resources in the jar with Thread.currentThread().getContextClassLoader(),but in OSGi environment,this class loader will be the other bundler's cl,so the issue occurs. To resolve this , we can use Resources.setDefaultClassLoader before ibatis is initalized,but this is not a very clean way. So, we suggest ibatis always find the dtd in the "JAR" and not in the classpath . |

And how do you propose to do that?

1. find which the jar "com.ibatis.common.resources.Resources" is in
2. load the resource "xxx.dtd" from the jar use the ClassLoader which load the "com.ibatis.common.resources.Resources" class this maybe work, and is inspired by the yui compressor's JarClassLoader

You could do this pretty transparently:
1) try Thread.blah.blah.blah to get the resource 2) if the resource is null, use Resources.class.getClassLoader() Make the change, write a test, and attach the source files to a JIRA issue.

Yes, that would be best. Too bad that OSGi doesn't allow for the
generally accepted best practice here... but Larry's suggestion would work well. I look forward to the patch.
