T5: How to load image Asset from filesystem?
Hello
I want to load images from the filesystem, like for example
D:/category/1/products/55/thumb.jpg
So the file path is dynamic and is based on the categoryId and the
productId.
How can I load such an image into my webpage using a Tapestry Asset?
This looks like a common usecase to me, but I couldn't find any info about
it.
Has somebody already done this? And could he/she show me some code examples?
Any help is welcome!
Thanks,
Peter

Hi Daniel,
Currently I load my (user uploaded) images using a StreamResponse as you
explained.
The pictures are shown in my webpage, but for every loaded picture the
onActivate is called.
With a result list of 15 rows per page, this is 16 times. In my onActivate I
also call my doSearch method.
So this behaviour is not what I want. Is there a way to solve this problem?
Thanks!
Peter

Thanks for pointing that out Luther. I copied it from a project using an

Great example - similar to an example on the Wiki ...
Note that 'createActionLink' was deprecated ...
http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry5/ComponentResources.html#createActionLink(java.lang.String,%20boolean,%20java.lang.Object..

Hi Peter,
I'm using nabble to post and it seems to have stripped out the img tag.
you need an img tag in your template and set the src attribute to
${imagePath}
img src="${imagePath}"
Hope this helps,
Daniel

Hi Daniel,
Thanks for your example. I tried this one, but the Object onImage is never
called when the page loads.
I am using Tapestry 5.1. The code is equal to your example.
What could I do wrong?

PAGE CLASS
inject component resources so that you can create an action link
@Inject
private ComponentResources mComponentResources;
when the path is requested by the template, create and return an action link
public Link getImagePath() {
return mComponentResources.createActionLink("image", false,
mItem.getID());
}
handle this action link
public Object onImage(long pID) {
"StreamResponseBuilder" is a class that I have implemented, it basically
figures out what image to served based on
the id passed in the context and then gets an "InputStream" for the image
file on disk and creates and returns a "StreamResponse", so essentially you
want this action handler to return a "StreamResponse" of the image you want
to display.
return StreamResponseBuilder.getItemImage(pID);
}
PAGE TEMPLATE
${imagePath}
Hope this helps

Daniel

Anyway you are right: exposing the full path in the html source is
certainly not a good idea.

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?

Re: T5: How to load image Asset from filesystem?
Posted by Peter Kanze <pe...@gmail.com>.
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);
}

The proposed solution in the issue is a bit different. Both is possible,
I hope the developers pick up the issue and choose a nice solution.

+1 to that. I guess we only have to decide if only one root directory
will be used or more than one.
By the way, nice example. :)

Re: T5: How to load image Asset from filesystem?

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());
}
}

Re: T5: How to load image Asset from filesystem?
Posted by Peter Kanze <pe...@gmail.com>.
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?

Hello
I already searched the archive and found the question, but it is not clear
to me.
There are no examples in it with a dynamic path..
