How to pick multiple files at once using JSF 1.2.
I am able to upload multiple files using rich faces(only one file selection at once), but can't pick multiple files at once. Prime faces provides support for multi file upload but to work with Prime Faces, JSF2.x version is required. We are stick to JSF 1.2.
In rich faces <rich:fileUpload/> tag has an attribute allowFlash, if we make this value as true it allows us to select multiple files, but after selecting multiple files its throwing an error saying
ContentTypeList does not contain a supported content type: text/*
After throwing error, even the upload button dissapears
Even I referred few other libraries like blue imp jquery multi file upload but I have zero knowledge on jquery and I don't find any example related to JSF1.x file upload.
Can anybody knows the solution?.
If your application runs on a JavaEE 6 application server or on a (with JSF 2.x configured) servlet container, take a look at Primefaces file upload component. It supports multiple file selection for a modern browsers. You could set file pattern to be accepted only *.zip files from browser's file selection dialog, using:
<p:fileUpload fileUploadListener="#{bean.listenerMethod}" mode="advanced" multiple="true" allowTypes="/(\.|\/)(zip)$/" />
For a legacy JSF 1.2 environment you could use Primefaces <= 2.1 or as mentioned #VasilLukach RichFaces 3.3.3 file upload component. Both of them support only single file selection (in order to upload several files, user have to click on a file selection button several times).
See more examples and/or documentation in linked showcases above.
Regardless of the used component library, your use case mentioned in comment:
I need to select all the three zip files from browser , then extract individual zip files and upload them into server
seems to be wrong. Usually user choose one or several files to be uploaded and then they are processed after transmission by your application on the server-side (unzip, persist or whatever else).

I know there are lots of similar questions like this in the web, but I haven't got to one working solution after searching for these last 2 days. Some threads are outdated, others solutions don't work, others are too complicated to manage, so... Yes, another question about resources.axd files in asp.net projects.
I'm starting to build a set of server controls and embedding some resources. After building my controls and dragging them into pages, each individual resource is requested by the browser in the form of an .axd script. I understand the part where the ScriptManager manages these scripts and they're not ready to use, for instance, in Bundles in some sort of .Include("*.axd").
I tried some of the combine/minify/compress/gzip/icecreamOnTop packages out there but couldn't manage none of them to work.
I tried the StriptManager CompositeScript approach and the ScriptResources.axd are indeed combined, the response is successful (code 200), but in the end the scripts don't work. Example: I included the jQuery lib in that composite script and then tried to use it in the page - didn't work. I must say I didn't reference () the composite script anywhere because I didn't understand how to do it. If I set the path, then a 404 was returned (found the 1024 byte limit threads, etc...) and all the requests to the WebResources.axd would still remain.
I would prefer not to write an HttpHandler myself.
Also tried to download the AjaxToolkit and tried the ToolkitScriptManager which combines scripts, but that added ~4seconds to my page load. No, thanks.
My question is: what is the current approach regarding this matter in .net 4.5?
I will have lots of resources and would like to combine them. All js and css files in the final website project are bundled, but how to 'bundle' the axd files?
Here's a little example which will make the following requests:

I know I can set the AjaxFrameworkMode to Disabled and will only have the 2 first WebResources.axd requests in this example, but what about when I have 10 css files embedded in my controls?
Any working solution would be much appreciated.
Many thanks
I managed to implement something that suits my case. More of a work around than a proper combining solution, but works and that's good enough for now.
All my controls extend a base class which has a property called ProcessResources. By default this property is set to true. That means that JS and CSS resources will be registered and each control has everything to work as standalone (axd resources will be generated). When set to false, no resource is registered and no axd files are generated.
The base class also has a static method that receives a destination path as a parameter and copies all the JS and CSS resources to that folder (if they don't exist or have been modified). This method returns a collection of all the needed resources for the control to work.
This way, on Application_Start, I can do something like:
myJsBundle.Inlude(ServerControlA.GetResources("~/ExternalResources", RESOURCES.JAVASCRIPT));
Then just need to set the ProcessResources flag to false (each control or web.config). All resources are now bundled and no axd files are generated.
I have excel importer in my application when I click on the "Upload" button I will get a pop up window with file upload screen where I can select the excel from the specified path. How to handle this in Robot Framework? Can any one help me how to handle the case?
Selenium2Library provides Choose File keyword for the same.
It takes two arguments, first is locator for the button and second is path to the file which needs to be uploaded.
e.g.
Choose File xpath=.//div/input ${TEMPDIR}${/}file_pa.csv
If you're using a dialog or input that WebDriver can interact with, then Sachin's answer about Choose File is the way to go.
If you're talking about the pre-HTML5 file-chooser dialogs provided by the browser, then Selenium2Library can't do this. However RobotFramework isn't just a wrapper around Selenium2Library so you can use something else that allows you to interact with the file upload screen.
I've done it in the past using AutoIt.
If you're not explicitly testing the upload dialog (and why should you, since it's provided as an atomic widget by your browser) then you should consider ways to simply avoid it. Perhaps a simple rest interface for uploading files.
I need to publish out a large XML file (~8MB = ~28,000 lines) from Tridion (2011 SP1 HR1) on to the web sever(s).
I have done this in the past with similar sized XML documents by uploading the XML file in to a Multimedia Component in Tridion and then having a simple Component Template to render the contents of the file at publish time. However, in the Tridion implementation in which I am working there is already a mechanism for publishing out content to the site using a very simple 'Code' Content (not Multimedia) Component which has a single plain text field for the 'code'.
The problem that I am having is that the browser becomes unresponsive/crashes when I try to paste such a large amount of content in to the 'Code' Component. Does anyone know of a way (either in the browser or in Tridion) to make this possible? I do have the option of adding a Component Template to process this as a Multimedia Component, but I would be reluctant to do this if I could get the existing mechanism working.
I have tried this in IE, Chrome and Firefox. I have also tried uploading this using WebDav without success too. We have already increased the HTTP Upload size on the server to 0.5GB to accommodate large binary files.
Thanks,
Jonathan
The first thing that comes to mind is the WCF size restrictions in the CoreService configuration.
These are set in the Web.Config of the CME, under (by default): C:\Program Files (x86)\Tridion\web\WebUI\WebRoot
How to prevent exe file upload in asp.net mvc.
If you are trying to prevent users uploading dangerous content, preventing them to upload exe files isn't enough. This is a black list approach. Much better is to ask yourself what are the valid file types you do support and block all others. This is a white list.
To allow certain file types you can check for the extension, but perhaps also validate the file header (the first couple of bytes from a file) to detect whether it is actually of the type you expect. You will have to figure out for each file type what the possible headers are.
Good luck.
So I'm writing a Django based website that allows users select a color scheme through an administration interface.
I already have middleware/context processors that links the current request (based on domain) to the account.
My question is how to dynamically serve the CSS with the account's custom color scheme.
I see two options:
Add a CSS block to the base template that overrides the styles w/variables passed in through a context processors.
Use a custom URL (e.g. "/static/dynamic/css/< website_id >/styles.css") that gets routed to a view that grabs all the necessary values and creates the css file.
I'm content with either option, but was wondering if anyone else out there has dealt with similar problems and could give some insight as to "Best Practices".
Update : I'm leaning towards option number 2, as I think this will allow for better caching down the road. So it's dynamic the first time, gets stored in memcache (or whatever), and invalidated when a user updates their settings in the admin site.
Update: Firstly, I'd like to thank everyone for their suggestions thus far. All the answers thus far have focused around generating static files. Though this would work great in production, it feels like a tremendous burden during development. If I wanted to add a new element to be styled, or tweak existing styles I'd have to go through and recreate each and every css file. Sure, this could be done with a management command, but I just don't feel it's worth it. Doing it dynamically would add 1 maybe 2 queries to each page load, which is something I'm not worried about at this stage. All I need to know is that at some point I will be able to cache it without rewriting the whole thing.
I've used option #2 with success. There are 2 decent ways of updating the generated static files that I know of:
Use a version querystring like /special_path.css?v=11452354234 where the v parameter is generated from a database field, key in memcached, or some other persistent file. Version gets updated by admin, or for development you would just make the generation not save if the parameter was something special like v=-1. You'll need a process to clean up the old generations after some time.
Don't use a version querystring, but have it look first for the generated file, if it can't find it, it generates it. You can create a cron job or WSGI app that looks for filesystem changes for development, and have a hook from your admin panel that deletes generations after an update. Here's an example of the monitoring, which you would have to convert to be specific to your generations and not to Django. http://code.google.com/p/modwsgi/wiki/ReloadingSourceCode#Monitoring%5FFor%5FCode%5FChanges
Could generate the css and store it in a textfield in the same model as the user profile/settings. Could then have a view to recreate them if you change a style. Then do your option 1 above.
Nice question.
I would suggest to pre-generate css file after colors scheme is saved. This would have positive impact on caching and overall page loading time. You can store your css files in directory /media/css/custom/<id or stometing>/styles.css or /media/css/custom/<id or sth>.css and in template add <link rel="stylesheet" href="/media/css/custom/{{some_var_pointing _to_file_name}}" />
You can also do the trick with some random number or date in css file name that could be changed each time file is saved. Thanks to this browser will load the file immediately in case of changes.
UPDATE: example of using model to improve this example
To make managing of those file easy you can create simple model (one per user):
class UserCSS(models.Model):
bg_color = models.CharField(..)
...
...
Fields (like bg_color) can represent parts of your css file. You can ovveride save method to add logic that creates css file for user (by rendering some template).
In case your file format change you can make changes in your's model definition (with some default values for new fields), make little changes in template and run save method for each exisintg instance of class. This would renew your css files.
That should work nicely.
I would create an md5 key with the theme elements, store this key in the user profile and create a ccs file named after this md5 key : you gain static file access and automatic theme change detection.
