Re: [T5] Asset Url is changed via domain. Meet Problems when use Alias or AliasOverrides
hmm. Is there an AssetFactory?

Actually, I met the problems (asset, asset cache ) in last month. At the
time, I created a service "AssetHelper" that having a method
"getAsset(String path)". When I want to access resource (css, js, image
...), I used the service. It means that some way like that ${asset:...},
@inj...@path... can not be used
Now, I see my old way is not convenient. so, I try to solve the problem
by using the ways of T5 ( ${asset:tapestry_banner.gif}, ).
This is my code:
public class AssetSourceDecorator implements AssetSource {
...
private AssetSource _t5AssetSource;
public AssetSourceDecorator(AssetSource assetSource) {
logger.info(">>>AssetSourceDecorator");
*_t5AssetSource = assetSource;*
}
public Asset getAsset(Resource baseResource, String path, Locale
locale) {
logger.info(">>>getAsset " + path );
path = modifyPath(path);
*return _t5AssetSource.getAsset(baseResource, path, locale);*
}
...
}
public class AppModule {
public static AssetSource decorateAssetSource(AssetSource assetSource) {
return new AssetSourceDecorator(assetSource);
}
}

Hi all,
This is my problems when I use Alias or AliasOverrides. Please help me
correct them.
_*Context: *_
IndexPage.tml
MyComponent.tml
-=> url of image.gif is ".../components/image.gif"
In my app - business logic, theme and template are used. They are
changed via *domain*. It means above image url will change via domain. Ex:
- If end user go to my app site in "domain1.com", url of image should be
"/components/*domain1.com*/image.gif"
- ... "domain2.com", "/components/*domain2.com*/image.gif"
(domain1 and domain both specify same IP)
_*My solution:*_ Override service AssetSource (trig it to change path)
MyAssetSource.java
public class MyAssetSource extends AssetSourceImpl {
...
@Override
public Asset getClasspathAsset(String path) {
path = modifyPath(path); return getClasspathAsset(path, null);
}
...
}
Then, Use MyAssetSource to override T5 AssetSource service
binder.bind(AssetSource.class, MyAssetSource.class).withId(
"MyAssetSource");
public void contributeAlias(Configuration configuration,
@InjectService("MyAssetSource") AssetSource assetSource) {
configuration
.add(AliasContribution.create(AssetSource.class, assetSource));
}
_*Problem:
*_ - T5 throws error when go to index page:
No adapter from type
org.apache.tapestry5.ioc.internal.util.ClasspathResource to type
org.apache.tapestry5.services.AssetFactory is available (registered
types are (none))
_*
*_- In another way, I use contributeAliasOverrides method but I also get
some errors. Look like I don't know how to use alias and aliasOverride!
Please tell me how use Alias or contributeAliasOverrides.
Thanks.
