Tapestry has built in support for serving classpath assets.

Option1
TML
   

Option2

@Inject AssetSource assetSource;

   public String getAssetUrl() {
  return
assetSource.getClasspathAsset("regoznapp/enterprise/src/main/resources/return.txt",
null).toClientURL();

Hi Petr!

You are really refering to a file in your src directory? When you use maven to 
build it the file is copied to target/ and you access it simply by "return.txt" 
using the classloader because target/resources is stripped when building the 
jar/war.

Set a break point and check if you really got an inputstream. You can also try 
to get the URL first which is null in case nothing found.

1. What happens? Is an exception thrown?

2. If you upload to the file system, like the jumpstart example does; then you 
should download from the file system - but your example, below, is downloading 
from a path relative to the classpath of the web app. Try this instead:

inputStream = new FileInputStream(myFilePath);

How to add a link to a file stored in directory?

2013-06-04 Thread Petr Janata 
Hi,

thanks for links with ideas. I am new in Tapestry I use Example
App
from
Jumpstart tutorial . I added File
Upload
to
Example App and HSQL table for uploaded file names. In Example App is
used Protecting
Pages
and
I can not download uploaded file by simple href even if I am logged in as a
admin user.

How to allow to download file from upload-path?

I use simple link in  tml file

download

and I also added  onReturnStreamResponse into java file from jumpstart
tutorial from this link.

StreamResponse onReturnStreamResponse() {
return new StreamResponse() {
InputStream inputStream;

@Override
public void prepareResponse(Response response) {
ClassLoader classLoader =
Thread.currentThread().getContextClassLoader();
inputStream =
classLoader.getResourceAsStream("regoznapp/enterprise/src/main/resources/return.txt");

// Set content length to prevent chunking - see
//
http://tapestry-users.832.n2.nabble.com/Disable-Transfer-Encoding-chunked-from-StreamResponse-td5269662.html#a5269662

try {
response.setHeader("Content-Length", "" +
inputStream.available());
}
catch (IOException e) {
// Ignore the exception in this simple example.
}
}

@Override
public String getContentType() {
return "text/plain";
}

@Override
public InputStream getStream() throws IOException {
return inputStream;
}
};
}

Put your files in the web app , or some external source (e.g. Amazon S3).
Putting the files in some arbitary folder in the host is not auto suported
by tapestry. You could write a file factory and there was a few topics
around this. For the time I wanted to the same but in the end I decided to
use S3.

Hi Petr!

Have a look at:
http://tawus.wordpress.com/2011/07/30/tapestry-jfreechart-integration/

Here you can see how to stream any kind of data.


StreamResponse was discussed here before:
http://apache-tapestry-mailing-list-archives.1045711.n5.nabble.com/T5-1-Return-a-file-as-response-of-a-ActionLink-event-td2437679.html


And you can find more here:
http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/StreamResponse.html

or on JumpStart which is a great source to start from anyway
