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

[mailingl...@j-b-s.de]

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.

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

[Geoff Callender]

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);

I know about usage of clientId. I don't completely understand - is it
connected somehow with invalid FormFragment state after zone update?

I'm using multiple zone update. Hence, it's AjaxResponseRenderer and void

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

[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;
}
};
}

Re: Contribute multiple collections in the same service?

[Howard Lewis Ship]

There's a huge complexity cost for allowing a single service to expose
multiple configurations, and its rare to need. Often, a solution that
breaks the single service into two (or more) services, even if just to
support the constraint of a single configuration, leads to better, more
testable code anyway.

I'm not sure I understand you, how would this differ from the case with
MethodInvoication?
Isn't the same AuthorizingRealm will check permissions for you?
Just check if your permission has targets set and if it has - you can just
peek instance from them.
If not - try to get if from MethodInvoication.

Anyway, if you need that invocation - you can create one - just call some
method from your new component newPermission2 and intercept that call with
@RequiresPermissions. But you can't declare dynamic permission in the
annotation, you do understand this, right?




By using the MethodInvocation (and perhaps actually getting the 
instance), I get the object to inspect directly, instead of having to 
get Cayenne to retrieve it for me via the object id.


What I've done is to create a realm that uses reflection / introspection 
to find methods annotated with a special annotation. The string in that 
annotation matches exactly with the permission being checked. When 
permission checks come in, they are dispatched to the method marked as 
being responsible for that permission.


So this:
@RequiresPermissions(ILACAuth.SERVICE_MANAGE_VIEW_INSTANCE)
public void onActivate(Service service) {

ends up getting processed by this:
@InstanceAccessMethod(ILACAuth.SERVICE_MANAGE_VIEW_INSTANCE)
public boolean isPermittedViewService() {
  MethodInvocation methodInvocation = getInvocation();

  if (methodInvocation == null) {
return false;
  }

  Object instance = methodInvocation.getInstance();
...
}

Where the permission is: servicemanager:view:instance.

This idea works everywhere, except for template rendering. I do support 
passing in the permission being checked when dispatching the call. I 
just need to get around the exact string matching I'm doing. This will 
probably require a locally reserved word in the permission to make it work.


So to handle the template scenario, I probably need to do something 
like: servicemanager:view:instance:key:265 and then know to chop :key on 
to dispatch to the correct check, and pass the permission in so it can 
have Cayenne retrieve the correct record if necessary. My method would 
have to change as well. It's not insurmountable, it just requires more 
work to set everything up.


The key thing is I now understand that I can't get what I need via 
MethodInvocation when rendering, so I don't bang my head against that wall.


Thanks,
Richard

Re: Tapestry links not https

[Dmitry Gusev]

Here's how I solve this problem with Tomcat and OpenShift:

I declare these Symbol values:

tapestry.hostname=.rhcloud.com
tapestry.hostport=80
tapestry.hostport-secure=443
tapestry.secure-enabled=true

I put @Secure to my pages.

And I declare RemoteIpValve in my application context like this:











This tomcat instance is running on port 8080 and 8433 in the cloud.

You may also want to look at: MetaDatConstants.SECURE_PAGE. I know even 
with AJP proxying to Tomcat, we've ran into troubles. We just set that 
to true when in production, and that fixes our links.

and in Java:

public String getMyPermission()

}

will this work?

I've ran into a bit of a problem however. I can do the instance level

The problem I'm running into is with the soft checks, in particular
 where I want to

That will trigger the checks, however, that doesn't populate the
Environment with the MethodInvocation. So I have no way of telling what is

Is there a way to get the current invocation without going through the

This section of Tapestry is still confusing to me, so I hope that my

Re: Contribute multiple collections in the same service?

[Lance Java]

Yes, this is a limitation of tapestry contributions. This can be worked
around.

Create a MapConfigProvider service which has a getter for the MapConfig
collection. Contribute MapConfig objects to the MapConfigProvider.

Then pass the MapConfigProvider and the second collection to your
HazelcastConfigServiceImpl.

Contribute multiple collections in the same service?

[Ferran Maylinch]

Hello,

I would like to contribute 2 collections to a service, but I am afraid
Tapestry only supports one collection to be contributed. Am I right?

My service constructor is like this:

public HazelcastConfigServiceImpl(
 final Collection mapConfigs,
final Collection hzConfigurers) { ... }

And I try to contribute the hzConfigurers this way:

@Contribute(HazelcastConfigService.class)
 public static void
contributeExecutorConfig(Configuration hzConfigurers)
 {
hzConfigurers.add(new HazelcastConfigurer()
 {
@Override
 public void configure(Config config)
{
 config.addExecutorConfig(
new ExecutorConfig(RankingsConstants.RANKINGS_EXECUTOR_SERVICE_NAME)
 .setCorePoolSize(5)
.setMaxPoolSize(5)
 );
}
 });
}

But I get this exception:

Caused by: org.apache.tapestry5.ioc.util.UnknownValueException: Could not
find a coercion from type
com.mobivery.malcom.categories.rankings.workers.services.MalcomRankingsWorkersModule$1
to type com.hazelcast.config.MapConfig.

It seems it is trying to insert my HazelcastConfigurer into
the mapConfigs when it should go to the hzConfigurers.

Thank you

Re: FormFragment stops working after refreshing containing zone

Also, what are you returning from your submit event? zone or

You should return the latter

Short answer:

Long answer:
The form's zone parameter refers to the zone's clientId (not to be confused
with the serverside id). Tapestry will auto generate a unique clientId for
your zone unless you provide an explicit clientId.
