• WEB-INF/lib jars not found in JBoss 4.0.2 war deploy

  - by boongywoongy

  I have a simple web application (one jsp and one servlet) file that I've copied into jboss-4.0.2/server/default/deploy folder and it has successfully hot deployed as I can access the jsp page. However, when I invoke the servlet, I am getting a java.lan.NoClassDefFoundError. I suspect that the jars under the WEB-INF/lib directory within the war is not being picked up. The structure of my war is: META-INF --> MANIFEST.MF WEB-INF --> classes --> ...*.classes --> lib --> jcommon-1.0.16.jar jfreechart-1.0.13.jar servlet-api.jar index.jsp Anybody else have classloading issues in JBoss 4? Many thanks.

• Form based authentication in java

  - by Stardust

  I want to know how can I enable form based authentication in java through database. After connecting to database, how can I verify whether the username and password, which I'm entering through html page is correct or not? Do I have to change action servlets from j_security_check to another my own defined servlets, which will connect to database and do all its verification on its own? Or I've to send authentication information to j_security_check, which will automatically connect to database, verify username and password. I'm successful in connecting to database through context.xml file, which is in META-INF directory of my own web application, but I'm not able to understand what's more I've to do enable form based authentication. I'm using Tomcat 6 as web server.

• How to order <script> tags vs. <style> tags in HTML markup for best results.

  - by Tchalvak

  I'm building up my site over at http://royronalds.com, and I'm trying to figure out what order of elements in the <head> makes most sense. Just to take from what I current have, I have: <head> <style> external stylesheet <meta> <title> <link> to favicon <script> for jQuery <script> main javascript for site <script> google analytics, asynchronous script. </head> Are there reasons to order these differently so that load times and other issues happen more smoothly, and if so, what would the ideal order be?

• image rendering issue

  - by burkejam71

  I am running Apache/2.2.3 (CentOS). For some reason certain images, jpg, gif, or png will show up as byte code when accessed directly on the server. Firefox 3 and Safari both think the content type is text/html. IE I believe has something built in to recognize it is an image and ignore the content type and renders the image correctly regardless. I can't seem to find anyone else with this issue. An example of this can be found at http://www.thedacs.com/admin/gp/userfiles/image/gp28%5Fimg%5F01.jpg but the image below on same server the image is rendered correctly (use same path from above) Fig3mod.jpg The first image works fine in Photoshop CS, Illistrator, GIMP, Paint.net,and any other image editing software. I have tried everything when editing the images from trying multiple file formats to print screens and cropping to create a new image to lose old image meta data. Can anybody help?

• How to select saxon TransformerFactory in Java

  - by pAkY88

  In my web application I need to use Saxon TransformerFactory to use XSLT 2.0 but I can't use setProperty method because I haven't this right on the web server and there is a Security Manager. So i have read that it's possible to do this: Use the Services API (as detailed in the JAR specification), if available, to determine the classname. The Services API will look for a classname in the file META-INF/services/javax.xml.transform.TransformerFactory in jars available to the runtime. I found this file in WEB-INF/lib/saxon9.jar but when I istantiate a TransformerFactory is always selected default factory and not saxon factory. How can I select Saxon Transformer Factory? Thanks

• How can I stop sorl thumbnail from breaking with very long filenames?

  - by bitbutter

  I've noticed that when working with SORL thumbnail, sometimes a user will upload an image with a very long filename, longer than the varfield in the database can hold. The name gets truncated in the database and the project gives errors whenever the image is requested. Is there a smart and safe way to have django automatically truncate long filenames in sorl uploads (prior to saving them in the database) to prevent this sort of thing? As reference, here's how the relevant model from my current project looks: class ArtistImage(models.Model): artist = models.ForeignKey(Artist) position = models.IntegerField() image = ThumbnailField( thumbnail_tag='<span class="artistimagewrapper"><img class="artistimage" src="%(src)s" width="%(width)s" height="%(height)s"></span>', upload_to='uploaded_images/artistimages', size=(900,900), quality=100, options={'crop': 'center'}, extra_thumbnails={ 'small':{ 'size':(92,92), 'quality':100, 'options':{'crop': 'center'}, } } ) class Meta: ordering = ('image',) def __unicode__(self): return (u"%s" % self.image)

• Convert string to JSON using Python

  - by Luiz Fernando

  Hi, I'm a little bit confused with JSON in Python. To me, it seems like a dictionary, and for that reason I'm trying to do that: json = """{ "glossary": { "title": "example glossary", "GlossDiv": { "title": "S", "GlossList": { "GlossEntry": { "ID": "SGML", "SortAs": "SGML", "GlossTerm": "Standard Generalized Markup Language", "Acronym": "SGML", "Abbrev": "ISO 8879:1986", "GlossDef": { "para": "A meta-markup language, used to create markup languages such as DocBook.", "GlossSeeAlso": ["GML", "XML"] }, "GlossSee": "markup" } } } } } """ But when I do print dict(json), it gives an error. How can I transform this string into a structure and then call json["title"] to obtain "example glossary"? Thanks.

• Using LDAP Attributes to improve performance for large directories

  - by Vineet Bhatia

  We have a LDAP directory with more than 50,000 users in it. LDAP Vendor suggests maximum limit of 40,000 users per LDAP group. We have number of inactive users and those are being purged but what if we don't get below the 40,000 users? Would switching to using multivalued attribute at user record level instead of using LDAP groups yield better performance during authentication, adding new users, etc? I know most server software (portal, application servers, etc) use LDAP groups. But, we have a standardized web service interface for access control instead of relying on server software to map LDAP groups to security roles. Each application uses this common "access control web service". Security roles are used within application to build fine-grained ACL used within each enterprise application.

• Regex to detect a proper permalink?

  - by Fedor

  These permalinks above are rerouted to my page: page.php?permalink=events/foo page.php?permalink=events/foo/ page.php?permalink=ru/events/foo page.php?permalink=ru/events/foo/ The events is dynamic, it could be specials or packages. My dilemma is basically; I need to detect an empty link in order so I can feed a robots no index meta tag in the case of: page.php?permalink=events page.php?permalink=events/ page.php?permalink=ru/events/ page.php?permalink=ru/events I can't use a simple pattern such as [a-zA-Z]+\/?(.+)/ since it won't work on the i18n permalinks. What regex could I use which would detect this, using $_GET['permalink'] as the reference to the permalinks? And avoid false positives? Update: Empty link means there's no fragment after the "events/" part. These are empty: page.php?permalink=events page.php?permalink=events/ page.php?permalink=ru/events/ page.php?permalink=ru/events

• Django blog reply system

  - by dana

  hello, i'm trying to build a mini reply system, based on the user's posts on a mini blog. Every post has a link named reply. if one presses reply, the reply form appears, and one edits the reply, and submits the form.The problem is that i don't know how to take the id of the post i want to reply to. In the view, if i use as a parameter one number (as an id of the blog post),it inserts the reply to the database. But how can i do it by not hardcoding? The view is: def save_reply(request): if request.method == 'POST': form = ReplyForm(request.POST) if form.is_valid(): new_obj = form.save(commit=False) new_obj.creator = request.user new_post = New(1) #it works only hardcoded new_obj.reply_to = new_post new_obj.save() return HttpResponseRedirect('.') else: form = ReplyForm() return render_to_response('replies/replies.html', { 'form': form, }, context_instance=RequestContext(request)) i have in forms.py: class ReplyForm(ModelForm): class Meta: model = Reply fields = ['reply'] and in models: class Reply(models.Model): reply_to = models.ForeignKey(New) creator = models.ForeignKey(User) reply = models.CharField(max_length=140,blank=False) objects = NewManager() mentioning that New is the micro blog class thanks

• Groovy MetaClass - Add category methods to appropriate metaClasses

  - by noah

  I have several categories that I use in my Grails plugin. e.g., class Foo { static foo(ClassA a,Object someArg) { ... } static bar(ClassB b,Object... someArgs) { ... } } I'm looking for the best way to add these methods to the meta-classes so that I don't have to use the category classes and can just invoke them as instance methods. e.g., aInstance.foo(someArg) bInstance.bar(someArgs) Is there a Groovy/Grails class or method that will help me do this or am I stuck iterating through the methods and adding them all myself?

• Attachment_fu error

  - by cswebgrl

  Hello, I am getting an error while trying to upload images on an Ubuntu machine that's running Rails 2.3.4, Ruby 1.8.6 using attachment_fu with image science. FreeImage exception for type ???: IPTC: Invalid key 'Tag 0x025C' The error seems to point to this line in the image_science_processor in the attachment_fu plugin: def with_image(file, &block) ::ImageScience.with_image file, &block end My initial thoughts are that it has something to do with meta tags and the images and maybe free image. I don't actually see this error on my dev machine - Mac Snow Leopard, Rails 2.3.5, Ruby 1.8.7. Before I start messing versions on the production boxes, has anyone else encountered this issue and have an idea to fix it? THANKS!!!!

• Django model manager didn't work with related object when I do aggregated query

  Hi, all. I'm having trouble doing an aggregation query on a many-to-many related field. Let's begin with my models: class SortedTagManager(models.Manager): use_for_related_fields = True def get_query_set(self): orig_query_set = super(SortedTagManager, self).get_query_set() # FIXME `used` is wrongly counted return orig_query_set.distinct().annotate( used=models.Count('users')).order_by('-used') class Tag(models.Model): content = models.CharField(max_length=32, unique=True) creator = models.ForeignKey(User, related_name='tags_i_created') users = models.ManyToManyField(User, through='TaggedNote', related_name='tags_i_used') objects_sorted_by_used = SortedTagManager() class TaggedNote(models.Model): """Association table of both (Tag , Note) and (Tag, User)""" note = models.ForeignKey(Note) # Note is what's tagged in my app tag = models.ForeignKey(Tag) tagged_by = models.ForeignKey(User) class Meta: unique_together = (('note', 'tag'),) However, the value of the aggregated field used is only correct when the model is queried directly: for t in Tag.objects.all(): print t.used # this works correctly for t in user.tags_i_used.all(): print t.used #prints n^2 when it should give n Would you please tell me what's wrong with it?

• How to Configure IIS 7.5 to Host Several Classic ASP Sites using 1 IP Address?

  - by SidC

  We are running Windows Server 2008 R2 with IIS 7.5 and have 4-5 Classic ASP sites to install. The main site is stored in wwwroot and the other sites are stored in folders below wwwroot. We have 1 IP address for the server. How do I configure IIS to allow folks to browse/test the sites before domain names are pointed to te server? When I setup one of the sites in a subfolder of wwwroot and assign a separate port to it, I receive a message stating: Config Error Cannot add duplicate collection entry of type 'add' with unique key attribute 'value' set to 'index.asp' How do I remedy this error and permit IIS to render the site?

• How do I use long names to refer to Group Managed Service Accounts (gMSA)?

  - by Jason Stangroome

  Commonly domain user accounts are used as service accounts. With domain user accounts, the username can easily be as long as 64 characters as long as the User Principal Name (UPN) is used to refer to the account, eg [email protected]. If you still use the legacy pre-Windows 2000 names (SAM) you have to truncate it to ~20 characters, eg mydomain\truncname. When using the New-ADServiceAccount PowerShell cmdlet to create a new Group Managed Service Account (gMSA) and a name longer than 15 characters is specified, an error is returned. To specify a longer name, the SAM name must be specified separately, eg: New-ADServiceAccount -Name longname -SamAccountName truncname ... To configure a service to run as the new gMSA, I can use the legacy username format mydomain\truncname$ but using usernames with a maximum of 15 characters in 2013 is a smell. How do I refer to a gMSA using the UPN-style format instead? I tried the longname$@domainfqdn approach but that didn't work. It also seems that the gMSA object in AD doesn't have a userPrincipalName attribute value specified.

• Special characters in PHP / MySQL

  - by Jonathan

  Hi, I have in the database words that include special character (in Spanish mostly, like tildes). In the database everything is saved and shown correctly with PHPmyAdmin, but when I get the data (using PHP) and display it in a browser, I get a weird character, like a "?" with a square... I need a general fix so I don't need to escape each character every time, and also I would be able to insert special Spanish characters from a PHP form into the database... The HTML is correct: <meta http-equiv="content-type" content="text/html; charset=utf-8" /> All tables and databas are set to utf8_spanish The character I get: ? Any suggestions??? Thanks!!!

• I started getting a weird message "Encrypting file system - Back up your file encryption key"

  I started getting a strange message when I start my computer. An icon appears in the system tray, and a popup tells me "Encrypting file system - Back up your file encryption key". I know what EFS is, but I don't use it. To my knowledge, I don't have any encrypted files on my partition. I have searched using Total Commander on all the partitions for files that have the "encrypted" attribute, but I found nothing. So I don't have any encrypted files. Does anyone know what I did to get this message?

• IE8 won't load JavaScript file in "Compatibility View."

  - by Don Jones

  Here's my JS insert: <script type="text/javascript" src="include/profile.js"></script> In IE8 with "Compatibility View," the file never loads. The first line in the file is a simple alert() call, so that I know it loaded. Change the browser to Standards View, and it loads fine. Also, if I add: <meta http-equiv="X-UA-Compatible" content="IE=100" > It forces to Standards View and it loads fine. Any idea why this would be the case? I've not been able to test against IE7, but I know the JS file also does not load in IE6. Right now the tag is in the section of the file.

• ASP.NET CustomValidator trying to match to System.EventHandler?

It's late and I'm tired, anybody know how to fix this or point out the glaring flaw in my comprehension?

• Accessing the feed/entry/id field of an ATOM 1.0 feed with the ROME library

  - by PartlyCloudy

  Hi, I feel a bit stupid asking this question, but I don't know how I can access the ID field of an entry when using ROME to parse an Atom feed. ROME provides it's own meta level of feeds/items, i.e. SyndFeed and SyndEntry. Being an abstraction over RSS and ATOM they only contain elements both formats support. Thus, there is no method to get an ID of an entry. There also exist low level packages for the distinct formats, and the Atom package contains com.sun.syndication.feed.atom.Entry, which provides getId(). However, I don't know how can I convert my SyndEntry into an Entry. I have not found a way to convert it. The (outdated) tutorials show a conversion, but that's only for output though. So how can I easily access the ID field? Thanks in advance.
