Hello, In my servlet I am using this code to open a pdf file in a browser, but instead it shows a download dialog box. Any help, what I am doing. Define a Java™ Servlet provided by the framework (typically a controller Java™ Servlet) . Methods added to ServletRequest to force a login and ability to logout . How can i force the browser to ask for the download prompt. May be this is not a ServletOutputStream op = ((HttpServletResponse) context. setHeader(" Content-Disposition", "attachment; filename=fyadocoodenes.tk");; response.

And, I suspect that it might get around the "content-disposition" issue. Good idea. Thanks for that. Got to admit I skipped over the octet-stream part, not really appreciating what it could do. I read that it was possible to change parameters in the server's httpd. Anyone else heard that the content-disposition header is going to be phased out of IE without a replacement? IE, Firefox download smoothly. Maybe I've missed something here, but I thought a much simpler approach to download the file would be to fool the browser into thinking that what you are downloading will need to have the "Save as" box open.

So why not just append this string to the end of the URL for the file in order to get it to do this? I made a servlet a couple years ago that would force a download of a specific type and a specific filename The servlet would be an inner 'directory' to the url:. I see this when I use a java agent in Domino 5. Have there been any good answers for that one? Have you seen any good articles on what to do about this, in general? Regards, N Wharton. I am having one problem with the servlet.

If i create a document with attachment in web and I tried to open that attachment after the save. I get page cannot be displayed and following error message in log. Agent error message: Malformed URL: I can open the attachments which are created in Lotus Notes using this servlets in browser immediatley after I saved the document. Our Server didn't have proper rights to the document.

I granted rights to that server and now it seems everything is working fine. IE6 browsers.

It's written in Perl. Instead use response. It tries to download file with added. Maybe it needs some additional header s?

In this case you must choose a smaller byte buffer. Just installed your solution a few weeks ago which works very well and I noticed that my server hard drive started running out of space. It seems that files that users downloaded are being saved on server hard drive - like a cache - at the time user does a download and it isn't being deleted after a successful download.

Is it an expected behavior of this servlet or is there a way to avoid this behavior? It seems someone writes article about flex in that blog. So you know there's at least two solutions Jake Howlett Category: Java Hat Tip: Servlet ; download ; attachment ;.

You can find me on Twitter and on Linked In. Using getRemoteUser is not the right way to make a servlet secure "in a Domino way". The right way would be to: Security Hi Jesper, Thanks for the feedback. Jake -codestore. Security I'm not sure of the detail, but there is going to be a difference in testing the user rights against the ACL, and assigning the servlet the permissions of the user according to the ACL.

Agents not good Originally I did use agents. As I said in the article, I didn't write this code and it reaching the extent of Java "capabilities" Jake -codestore.

Security Hi I still think that's the wrong way to go. You can handle the security yourself when it's simple, but in real life it is offen not. Security I think your all going about it the wrong way.

The best way to stop people from exploiting that script especially if it's just for attachments you want people to download is just create a directory specifically for the attachments, and have it coded in your script ie, unchangable in the variables That way you they can only download files from that directory, which presumably is full of files for them to download anyway.

Doesn't require any access checking or anything, just lateral thinking. I'm not questioning your idea just wondered why it makes a difference. Please enlighten. Good idea!

The content-type thing Hi Brian, Good idea. Anything that makes it IE proof has to be good Related possibilty I read that it was possible to change parameters in the server's httpd. Perhaps someone else will have more luck.

The content-type thing Anyone else heard that the content-disposition header is going to be phased out of IE without a replacement? Am I being incredibly thick? How about this - easier? Well it sounds good in theory but I can't get it to work. Have you got this to work in your own experience?

I saw a suggestion to use something like: Any idea? The servlet would be an inner 'directory' to the url: On Stopped Java Agents It can be specified at two levels: 1. User Level. This settings. Global Level.

Where appropriate, the default values values used when the setting is not specified are provided. If set to false, maven will use a sensible default value, perhaps based on some other setting, for the parameter in question. This will have an effect on artifact downloads, artifact deployment, and others. Maven will automatically add the group identifiers "org.

Unless otherwise specified by system property or command-line switch , the first proxy specification in this list marked as active will be used. Authentication profiles can be used whenever maven must make a connection to a remote server. It works like this: a POM may declare a repository to use in resolving certain artifacts.

However, this repository may have problems with heavy traffic at times, so people have mirrored it to several places. That repository definition will have a unique id, so we can create a mirror reference for that repository, to be used as an alternate download site.

The mirror site will be the preferred server for that repository. The repository that this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used for inheritance and direct lookup purposes, and must be unique across the set of mirrors. Profiles provided in the settings. For example, if you have an integration testing plugin - like cactus - that needs to know where your Tomcat instance is installed, you can provide a variable here such that the variable is dereferenced during the build process to configure the cactus plugin.

As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles section of this document settings. Another way essentially relies on the detection of a system property, either matching a particular value for the property, or merely testing its existence.

Profiles can also be activated by JDK version prefix, where a value of '1. Finally, the list of active profiles can be specified directly from the command line. NOTE: For profiles defined in the settings. An encouraged best practice for profile identification is to use a consistent naming convention for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.

This will make it more intuitive to understand what the set of introduced profiles is attempting to accomplish, particularly when you only have a list of profile id's for debug. To use this, your plugin configuration might hypothetically look like Default files created by the Maven archetype plugin To create an archetype project, perform these steps:: 1.

When prompted for additional information, specify Y. Change the command prompt to the generated project.

1. REST API to stream file with StreamingOutput

Run the following Maven command: mvn eclipse:eclipse After you run this command, you can import the project into Eclipse as discussed in the next section. Add Java files to the Maven project using Eclipse To make it easier to work with the Maven generated project, import it into the Eclipse development environment, as shown in the following illustration.

The Java class, named DownloadAssets, that you create in this section extends the Sling class named org. This class supports the doGet method that lets you sent a request to the servlet and get back a response in this use case, the response is a ZIP file.

In this development article, a QueryBuilder instance is injected into the doGet method. This instance is required to create a Session instance that lets you create a Query instance.

To inject a ResourceResolverFactory instance, you use the Reference annotation to define a class member, as shown in the following example. Later in this article, this is invoked using an href tag. Thank you!!
