IIS VirtualDirectories, and accessing their contents from a ASP.NET MVC Project

Asked 2021-Jun-02 at 15:32

With Chromium no longer allowing links to local files I am attempting to test a couple of solutions to allow users to open PDF's on a local Network Share without having to download them first (the current work around).

I tested a pure JavaScript solution and that one worked great.

However I am trying use a Virtual Directory in IIS that points to a Network share with the files the user(s) can access.

When testing and trying to navigate to the file I have saved I get a "cannot find path error"

I created a test application and published it on my local machine.

Below is the screenshot of the Virtual Directory I created.

**Below** is the code I use to try and open the file. ...

In ASP.NET Core you can return an VirtualFileResult

A FileResult that on execution writes the file specified using a virtual path to the response using mechanisms provided by the host.

Or you can do a Server.MapPath("~/pdf/light.pdf") to get the virtual path.

Returns the physical file path that corresponds to the specified virtual path.

In your example code you would use it as such:

From the snippets which are shared, I can grasp that iText 2 is used. If it is possible, it is better to reconsider such a choice, since iText 2 is more than 10 years old, potentially has a lot of functional and security issues and no longer maintained.

I recommend updating to iText 7. Although I do not have your code and thus could not prove that in your case setting color would not make the size of the PDF much bigger, I have created the following sample to demonstrate that there should no issue:

Primefaces 10 dataTable p:dataExporter generate ArrayIndexOutOfBoundsException on render after migration

Asked 2021-Apr-16 at 11:58

Environment:

Jboss 7.2
Primefaces 10
Java 11

I have migrated from primefaces 8 to primefaces 10 dataTable p:dataExporter generate ArrayIndexOutOfBoundsException on render the xhtml. When I comment out dataexporter the xhtml render well.

Following the migration guide the only important change seems to be taht PDF library has been switched from iText to Libre OpenPDF.

I've tried two differents contexts and one works and one not, differences:

The context that it works, does not have authentication
The context that it does not work, have keycloack authentication and two themes dependencies.

I don't think is related with primefaces themes but it could be because of keycloak as it shows handeling request in log error.

Any reason why is giving this error?

I finally found the problem why I could not export files with p:dataExporter.

The web.xml file contained the context param javax.faces.PARTIAL_STATE_SAVING defined to false, so I commented out and I worked well!

Downloading public PDF file from S3 Bucket SwiftUI

Asked 2021-Feb-21 at 22:13

I am simply trying to store a static PDF in an S3 bucket which I can grab and present using Apple's built-in PDF Viewer. I am a having problems and a bit confused on a way to store the PDF locally in the proper form. I apologize if this is repeated or too simple, I have searched for hours on a proper solution but have not found anything that works. Thank you. I tried using the URL directly but that also threw an error.

Amplify.Storage.downloadData returns a Data object -- it doesn't actually download the file. But, there's another method downloadFile that will work for this.
Your applications Bundle has a static set of files. Once you save a file, you won't be looking in the Bundle, but rather in the app's documents or temp directory.
Rather than making the Amplify calls in the view body, probably better to assign it to a separate object (here I'm using an ObservableObject called DataLoader) to do the work at then set a flag (downloaded) when it's done.

Here is my code snippet for adding text into pdf file,

Your code does not add text into an existing pdf file. It creates a new PDF, adds text to it, and appends this new PDF to the existing file presumably already containing a PDF. The result is one file containing two PDFs.

Concatenating two files of the same type only seldom results in a valid file of that type. This does works for some textual formats (plain text, csv, ...) but hardly ever for binary formats, in particular not for PDFs.

Thus, your viewer gets to show a file which is invalid as a PDF, so your viewer could simply have displayed an error and quit. But PDF viewers are notorious for trying to repair the files they are given, each viewer in its own way. Thus, depending on the viewer you could also see either only the original file, only the new file, a combination of both, an empty file, or some other repair result.

So your observation,

but this will replace with all of the Pdf file, not just inserting into it

is not surprising but may well differ from viewer to viewer.

To actually change an existing file with OpenPDF (or any iText version before 6 or other library forked from such a version) you should read the existing PDF using a PdfReader, manipulate that reader in a PdfStamper, and close that stamper.
