Creating a tilesConfigurer for Spring Web does not work in an OSGi environment
------------------------------------------------------------------------------
Key: TILES-387
URL: https://issues.apache.org/struts/browse/TILES-387
Project: Tiles
Issue Type: Bug
Components: tiles-api, tiles-servlet
Affects Versions: 2.1.2
Environment: Any
Reporter: Bjorn Harvold
As of Tiles 2.1.1, the TilesConfigurer that was written by the Spring guys no
longer works as they are using deprecated attributes in Tiles. They are working
on a new tiles configurer for v3 of Spring. In the meantime, there have been
some solutions submitted by the community. They work in a regular environment
but not within an OSGi environment.
(see here for details on the issue raised:
http://jira.springframework.org/browse/SPR-5411)
The problem is this:
public SpringTilesConfigurer() {
this.tilesPropertyMap.put(
AbstractTilesApplicationContextFactory.APPLICATION_CONTEXT_FACTORY_INIT_PARAM,
WildcardServletTilesApplicationContextFactory.class.getName());
this.tilesPropertyMap.put(
TilesContainerFactory.PREPARER_FACTORY_INIT_PARAM,
BasicPreparerFactory.class.getName());
this.tilesPropertyMap.put(
DefinitionsFactory.LOCALE_RESOLVER_IMPL_PROPERTY,
SpringLocaleResolver.class.getName());
this.tilesPropertyMap.put(TilesContainerFactory.ATTRIBUTE_EVALUATOR_INIT_PARAM,
ELAttributeEvaluator.class.getName());
this.tilesPropertyMap.put(TilesContainerFactory.CONTAINER_FACTORY_MUTABLE_INIT_PARAM,
Boolean.toString(false));
}
protected TilesContainer createTilesContainer() throws TilesException {
ServletContextAdapter adaptedContext = new ServletContextAdapter(new
DelegatingServletConfig());
TilesApplicationContext preliminaryContext = new
ServletTilesApplicationContext(adaptedContext);
AbstractTilesApplicationContextFactory contextFactory =
AbstractTilesApplicationContextFactory.createFactory(preliminaryContext);
this.tilesContext =
contextFactory.createApplicationContext(adaptedContext);
AbstractTilesContainerFactory factory =
AbstractTilesContainerFactory.getTilesContainerFactory(this.tilesContext);
return factory.createContainer(this.tilesContext);
}
When trying to create the context factory, it will try to initialize
WildcardServletTilesApplicationContextFactory in
AbstractTilesApplicationContextFactory:80 with the help of ClassUtil. Now
WildcardServletTilesApplicationContextFactory is located in the tiles-servlet
bundle while ClassUtil is located in tiles-api. Tiles-api does not have an
import dependency on tiles-servlet (as it should be) so when ClassUtil tries to
instantiate the class it cannot find it. This problem also occurs when trying
to instantiate the TilesContainerFactory.
Is there something the Tiles team needs to do in order to make this a work
within OSGi or is the Spring community going at it the wrong way?
Cheers
bjorn
