I don't know much about the details how you contribute your
FilesystemAssetFactory. Never had time to take a briefer look at
tapestry-ioc.
Please note: in the previous example the AssetFactory is injected like this:
@Inject @ClasspathProvider
private AssetFactory assetFactory;
The @ClasspathProvider is necessary, so that tapestry-ioc knows, which of the
different implementations to inject.
Maybe, in order to make your solution work, you need to give a hint like that,
too?

Hi Andy,
Thanks for adding this to Jira.
See below my code what I have produced so far. The problem is that I now see
the complete filepath in my html source (<img src="
C:/tmp/pictures/8/71/1001/thumb1.jpg" alt=""/>)
I don't want the complete file url in my html source. How can I fix this.
And how do I map the html url to the file url?
The last problem is that the file url is correct, but the image is not shown
in my html page.
What am I doing wrong?
--Quick Example Code Below---
<img src="${ThumbnailPath}" alt="" />
public String getThumbnailPath() {
Asset asset = assetSource.getAsset(null,
"file:/8/71/1001/thumb1.jpg", null);
return asset.toClientURL();
}
public class FileSystemResource extends AbstractResource {
private static final int PRIME = 37;
public FileSystemResource(String path) {
super(path);
}
@Override
protected Resource newResource(String path) {
return new FileSystemResource(path);
}
@Override
public URL toURL() {
String filePath = getPath();
File file = new File(filePath);
if (file != null && file.exists()) {
try {
return file.toURL();
}
catch (MalformedURLException ex) {
throw new RuntimeException(ex);
}
}
return null;
}
}
public class FileSystemAssetFactory implements AssetFactory {
private static final String assetPath = "/images/";
public FileSystemAssetFactory() {
}
@Override
public Resource getRootResource() {
return new FileSystemResource("C:/tmp/pictures/");
}
@Override
public Asset createAsset(final Resource resource) {
final String filePath = resource.getPath();
return new Asset()
{
public Resource getResource()
{
return resource;
}
public String toClientURL()
{
return filePath;
}
/**
* Returns the client URL, which is essiential to allow informal
parameters of type
* Asset to generate a proper value.
*/
@Override
public String toString()
{
return toClientURL();
}
};
}
}
//In AppModule.java
public AssetFactory buildfileSystemAssetFactory() {
return new FileSystemAssetFactory();
}
public void contributeAssetSource(MappedConfiguration<String,
AssetFactory> configuration,
@InjectService("fileSystemAssetFactory") AssetFactory
fileSystemAssetFactory) {
configuration.add("file", fileSystemAssetFactory);
}

There is a ClasspathAssetFactory and a ContextAssetFactory. A useful
addition to the framework would be a FilesystemAssetFactory. I am going to
fill an JIRA issue about it.
The way I did it for classpath resources was very simple, see below. Only
the first two lines of renderIcon() are relevant for construction an asset.
@BeginRender
public void renderIcon(MarkupWriter writer) {
Resource iconResource = new ClasspathResource(BASE_PATH + src);
if(assetFactory == null) {
LOG.warn("assertFactory is null");
}
if(iconResource == null) {
LOG.warn("iconResource is null");
}
Asset icon = assetFactory.createAsset(iconResource);
if(icon != null) {
writer.element("img",
"src", icon.toClientURL(),
"alt", getAlt());
resources.renderInformalParameters(writer);
writer.end();
} else {
writer.writeRaw(getAlt());
}
}
@Inject @ClasspathProvider
private AssetFactory assetFactory;
@BeginRender
public void renderIcon(MarkupWriter writer) {
Resource iconResource = new ClasspathResource(BASE_PATH + src);
Asset icon = assetFactory.createAsset(iconResource);
if(icon != null) {
writer.element("img",
"src", icon.toClientURL(),
"alt", getAlt());
resources.renderInformalParameters(writer);
writer.end();
} else {
writer.writeRaw(getAlt());
}
}

The documentation (http://tapestry.apache.org/tapestry5/guide/assets.html
)
tells me to define a new AssetFactory and contribute it to the AssetSource
service configuration.
Yes okay, but how do I implement an AssetFactory? Is there any
documentation?
What do I need to do with public Resource getRootResource() and public
Asset
createAsset(Resource resource);
I also looked at ClasspathAssetFactory but don't understand it. The
comment
is too minimal.
Can someone help me with this?
Thanks,
Peter!

Oke thank you.
But how do I map between the web http:// and the file D:/ urls?
Can you give me some (pseudo) code examples how to do this?
Thanks!

I already searched the archive and found the question, but it is not

There are no examples in it with a dynamic path..
You'll use AssetSource for that.
