Dozer
Hi,
I am trying to use Dozer mapping inside felix. My mapping xml files run
without a problem in my unit tests, but when run inside OSGI I get
a ClassNotFoundException.

Does anyone know how to solve this problem in felix?

Unfortunately - libraries that use getContextClassLoader() for dynamic
classloading is a long standing nasty within a structured classloading
environment such as OSGi. The problem is the library is using a Thread
local attribute to determine for itself what classloader to use, which
defeats the handling OSGi would have done for it.
Your workaround is the one most of us use to get around this.

Hi,
there are three bundles where bundle A and B define and export package.
Bundle C contains the dozer mapping file and maps a class from A to a class
from B. Budle C throws a ClassNotFoundException.
I was able to work around the problem by setting
Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader());
package C;
public B transform(
A a) throws Exception {
//workaround
Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader());
List<String> myMappingFiles = new ArrayList<String>();
myMappingFiles.add(MAPPING_FILE);
DozerBeanMapper mapper = new DozerBeanMapper(myMappingFiles);
B b = new B();
mapper.map(a, b);//throws Exception
return b;
}
Regards,
Lee

The information given is not enough to know what is going on. What is
packaged inside of which bundles? Who imports, exports, etc?
