  • maven assemblies. Putting each dependency with transitive dependencies in own directory?

    - by jr
    I have a maven project which consists of a few modules. This is to be deployed on a client machine and will involve installing Tomcat and will make use of NSIS for installer. There is a separate application which monitors tomcat and can restart it, perform updates, etc. So, I have the modules setup as follows: project +-- client (all code, handlers, for the war) +-- client-common - (shared code, shared between monitor and client) +-- client-web - (the war, basically just uses war has applicationcontext, web.xml,etc) +-- monitor - (the monitor application jar. Uses wrapper to run) So, I need to create an installer. I was planning on creating another module which would be the installer. This is where I would have tomcat directory and I'd like maven to "assemble" everything and then run NSIS so I can create the final installer. However, I need to have the monitor jar file in a directory and then have all monitors dependencies in a lib/ directory. The final directory structure should be: project-installer-directory/monitor/monitor-version.jar project-installer-directory/monitor/lib/monitor-dep-1.jar project-installer-directory/monitor/lib/monitor-dep-2.jar project-installer-directory/monitor/lib/monitor-dep-3.jar project-installer-directory/webapps/client-web.war Where in the client-web\WEB-INF\lib directory we will have all client-web's dependencies after it is exploded. That works, I have the .war file. What I am having problems with is getting the monitor module dependencies independent of the dependencies of the client-web module. I tried to just create the installer module and make the monitor and client-web dependencies, but when I use dependencies-copy it gives me everything. Not what I want. I'm leaning towards creating a new module called monitor-assembly or something to give me a zip file which contains the directory format I need, but that is yet another module. Can someone please help me with the correct way to accomplish this? thanks!

  • How to write a flexible modular program with good interaction possibilities between modules?

    - by PeterK
    I went through answers on similar topics here on SO but could't find a satisfying answer. Since i know this is a rather large topic, i will try to be more specific. I want to write a program which processes files. The processing is nontrivial, so the best way is to split different phases into standalone modules which then would be used as necessary (since sometimes i will be only interested in the output of module A, sometimes i would need output of five other modules, etc). The thing is, that i need the modules to cooperate, because the output of one might be the input of another. And i need it to be FAST. Moreover i want to avoid doing certain processing more than once (if module A creates some data which then need to be processed by module B and C, i don't want to run module A twice to create the input for modules B,C ). The information the modules need to share would mostly be blocks of binary data and/or offsets into the processed files. The task of the main program would be quite simple - just parse arguments, run required modules (and perhaps give some output, or should this be the task of the modules?). I don't need the modules to be loaded at runtime. It's perfectly fine to have libs with a .h file and recompile the program every time there is a new module or some module is updated. The idea of modules is here mainly because of code readability, maintaining and to be able to have more people working on different modules without the need to have some predefined interface or whatever (on the other hand, some "guidelines" on how to write the modules would be probably required, i know that). We can assume that the file processing is a read-only operation, the original file is not changed. Could someone point me in a good direction on how to do this in C++ ? Any advice is wellcome (links, tutorials, pdf books...).

  • ASP.NET Web Application: use 1 or multiple virtual directories

    - by tster
    I am working on a (largish) internal web application which has multiple modules (security, execution, features, reports, etc.). All the pages in the app share navigation, CSS, JS, controls, etc. I want to make a single "Web Application" project, which includes all the pages for the app, then references various projects which will have the database and business logic in them. However, some of the people on the project want to have separate projects for the pages of each module. To make this more clear, this is what I'm advocating to be the projects. /WebInterface* /SecurityLib /ExecutionLib etc... And here is what they are advocating: /SecurityInterface* /SecutiryLib /ExecutionInterface* /ExecutionLib etc... *project will be published to a virtual directory of IIS Basically What I'm looking for is the advantages of both approaches. Here is what I can think of so far: Single Virtual Directory Pros Modules can share a single MasterPage Modules can share UserControls (this will be common) Links to other modules are within the same Virtual directory, and thus don't need to be fully qualified. Less chance of having incompatible module versions together. Multiple Virtual Directories Pros Can publish a new version of a single module without disrupting other modules Module is more compartmentalized. Less likely that changes will break other modules. I don't buy those arguments though. First, using load balanced servers (which we will have) we should be able to publish new versions of the project with zero downtime assuming there are no breaking database changes. Second, If something "breaks" another module, then there is either an improper dependency or the break will show up eventually in the other module, when the developers copy over the latest version of the UserControl, MasterPage or dll. As a point of reference, there are about 10 developers on the project for about 50% of their time. The initial development will be about 9 months.

  • Why does switching users completely hang my system every time?

    - by Stéphane
    I have a fresh install of 11.04 64bit, with 2 administrator accounts and 4 normal accounts. The 4 normal accounts (the kids' accounts) don't have passwords, they can login simply by clicking on their names. When any of the users -- either admin or normal -- tries to switch to another account by clicking in the top-right corner of the screen and selecting another user, the screen goes black and the entire system locks up. Even CTRL+ALT+F1 through F7 does nothing. This is reproducible 100% of the time on this system. I can ssh into the box when the console locks up, and by running top, I see that Xorg is consuming about 100% of the CPU. Looking at the output of "ps axfu" in bash while the system is in this "locked up" state, here is the lightdm and X process tree: USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1153 0.0 0.1 183508 4292 ?

  • Violation of the DRY Principle

    - by Onorio Catenacci
    I am sure there's a name for this anti-pattern somewhere; however I am not familiar enough with the anti-pattern literature to know it. Consider the following scenario: or0 is a member function in a class. For better or worse, it's heavily dependent on class member variables. Programmer A comes along and needs functionality like or0 but rather than calling or0, Programmer A copies and renames the entire class. I'm guessing that she doesn't call or0 because, as I say, it's heavily dependent on member variables for its functionality. Or maybe she's a junior programmer and doesn't know how to call it from other code. So now we've got or0 and c0 (c for copy). I can't completely fault Programmer A for this approach--we all get under tight deadlines and we hack code to get work done. Several programmers maintain or0 so it's now version orN. c0 is now version cN. Unfortunately most of the programmers that maintained the class containing or0 seemed to be completely unaware of c0--which is one of the strongest arguments I can think of for the wisdom of the DRY principle. And there may also have been independent maintainance of the code in c. Either way it appears that or0 and c0 were maintained independent of each other. And, joy and happiness, an error is occurring in cN that does not occur in orN. So I have a few questions: 1.) Is there a name for this anti-pattern? I've seen this happen so often I'd find it hard to believe this is not a named anti-pattern. 2.) I can see a few alternatives: a.) Fix orN to take a parameter that specifies the values of all the member variables it needs. Then modify cN to call orN with all of the needed parameters passed in. b.) Try to manually port fixes from orN to cN. (Mind you I don't want to do this but it is a realistic possibility.) c.) Recopy orN to cN--again, yuck but I list it for sake of completeness. d.) Try to figure out where cN is broken and then repair it independently of orN. Alternative a seems like the best fix in the long term but I doubt the customer will let me implement it. Never time or money to fix things right but always time and money to repair the same problem 40 or 50 times, right? Can anyone suggest other approaches I may not have considered? If you were in my place, which approach would you take? If there are other questions and answers here along these lines, please post links to them. I don't mind removing this question if it's a dupe but my searching hasn't turned up anything that addresses this question yet. EDIT: Thanks everyone for all the thoughtful responses. I asked about a name for the anti-pattern so I could research it further on my own. I'm surprised this particular bad coding practice doesn't seem to have a "canonical" name for it.

  • how to parse a Date string to java.Date

    - by hguser
    Hi: I have a date string and I wang to parse it to normal date use the java Date API,the following is my code: public static void main(String[] args) { String date="2010-10-02T12:23:23Z"; String pattern="yyyy-MM-ddThh:mm:ssZ"; SimpleDateFormat sdf=new SimpleDateFormat(pattern); try { Date d=sdf.parse(date); System.out.println(d.getYear()); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } } However I got a exception:java.lang.IllegalArgumentException: Illegal pattern character 'T' So I wonder if i have to split the string and parse it manually? BTW, I have tried to add a single quote character on either side of the T: String pattern="yyyy-MM-dd'T'hh:mm:ssZ"; It also does not work.

  • Using LIKE operator in LINQ to Entity

    - by Draconic
    Hi, everybody! Currently in our project we are using Entity Framework and LINQ. We want to create a search feature where the Client fills different filters but he isn't forced to. To do this "dynamic" query in LINQ, we thought about using the Like operator, searching either for the field, or "%" to get everything if the user didn't fill that field. The joke's on us when we discovered it didn't support Like. After some searching, we read several answers where it's sugested to use StartsWith, but it's useless for us. Is the only solution using something like: ObjectQuery<Contact> contacts = db.Contacts; if (pattern != "") { contacts = contacts.Where(“it.Name LIKE @pattern”); contacts.Parameters.Add(new ObjectParameter(“pattern”, pattern); } However, we'd like to stick with linq only. Happy coding!

  • Configuration problems with django and mod_wsgi

    Hi, I've got problems on getting django to work on apache 2.2 with mod_wsgi. Django is installed and mod_wsgi too. I can even see a 404 page when accessing the path and I can login to django admin. But if I want to install the tagging module I get the following error: Traceback (most recent call last): File "setup.py", line 49, in <module> version_tuple = __import__('tagging').VERSION File "/home/jim/django-tagging/tagging/__init__.py", line 3, in <module> from tagging.managers import ModelTaggedItemManager, TagDescriptor File "/home/jim/django-tagging/tagging/managers.py", line 5, in <module> from django.contrib.contenttypes.models import ContentType File "/usr/lib/python2.5/site-packages/django/contrib/contenttypes/models.py", line 1, in <module> from django.db import models File "/usr/lib/python2.5/site-packages/django/db/__init__.py", line 10, in <module> if not settings.DATABASE_ENGINE: File "/usr/lib/python2.5/site-packages/django/utils/functional.py", line 269, in __getattr__ self._setup() File "/usr/lib/python2.5/site-packages/django/conf/__init__.py", line 40, in _setup self._wrapped = Settings(settings_module) File "/usr/lib/python2.5/site-packages/django/conf/__init__.py", line 75, in __init__ raise ImportError, "Could not import settings '%s' (Is it on sys.path?

    - by Arg
    Hello, I am currently trying to get python bittorrent tracker running inside of jython and i encountered this problem: the tracker uses PyCrypto library which i compiled for my platform and added into the python path. When i try to run code, however, i get following error: Exception in thread "MainThread" Traceback (most recent call last): File "./python_dep/BitTorrent-5.2.2/bittorrent-tracker.py", line 21, in <module> from BitTorrent.track import track File "./python_dep/BitTorrent-5.2.2/BitTorrent/track.py", line 50, in <module> from BitTorrent.UI import Size File "./python_dep/BitTorrent-5.2.2/BitTorrent/UI.py", line 37, in <module> from BitTorrent.MultiTorrent import UnknownInfohash, TorrentAlreadyInQueue, TorrentAlreadyRunning, TorrentNotRunning File "./python_dep/BitTorrent-5.2.2/BitTorrent/MultiTorrent.py", line 25, in <module> from BitTorrent.Torrent import Feedback, Torrent File "./python_dep/BitTorrent-5.2.2/BitTorrent/Torrent.py", line 32, in <module> from BitTorrent.ConnectionManager import ConnectionManager File "./python_dep/BitTorrent-5.2.2/BitTorrent/ConnectionManager.py", line 22, in <module> from BitTorrent.Connector import Connector File "./python_dep/BitTorrent-5.2.2/BitTorrent/Connector.py", line 27, in <module> from Crypto.Cipher import ARC4 ImportError: cannot import name ARC4 Java Result: 1 I am pretty sure that the library is in the python path, because command import Crypto.Cipher works, while from Crypto.Cipher import ARC4 does not.

  • singleton vs factory?

    - by fayer
    i've got 3 Log classes that all implements iLog interface: DatabaseLog FileLog ScreenLog there can only be one instance of them. initially i though of using single pattern for each class but then i thought why not use a factory for instantiation instead, cause then i wont have to create single pattern for each one of them and for all future Log classes. and maybe someone would want them as multiple objects in the future. so my questions is: should i use factory or singleton pattern here?

  • Regex.Replace only replaces start of string

    - by Yannick Smits
    I'm trying to replace a friendly url pattern with a html url notation but due to lack of regex experience I can't figure out why my regex only replaces the first occurence of my pattern: string text = "[Hotel Des Terrasses \http://flash-hotel.fr/] and [Du Phare \http://www.activehotels.com/hotel/]"; text = Regex.Replace(text, @"\[(.+)\s*\\(.+)\]", "<a href=\"$2\" target=\"_blank\">$1</a>"); How can i make the second pattern be replaced with the HTML markup too?

  • How do I work around this problem creating a virtualenv environment with a custom-build Python?

  • Cocoa Touch UITableView Alphabetical '#' Match All Unmatched

    - by Kevin Sylvestre
    I have a UITableView containing names that I would like to group (and sort) by the first letter (similar to the Address Book application). I am currently able to match any section ('A'-'Z') using: // Sections is an array of strings "{search}" and "A" to "Z" and "#". NSString *pattern = [self.sections objectAtIndex:section]; NSPredicate *predicate = nil; // Ignore search pattern. if ([pattern isEqualToString:@"{search}"]) return nil; // Non-Alpha and Non-Diacritic-Alpha (?). if ([pattern isEqualToString:@"#"]); // Default case (use case and diacritic insensitivity). if (!predicate) predicate = [NSPredicate predicateWithFormat:@"name beginswith[cd] %@", pattern]; // Return filtered results. return [self.friends filteredArrayUsingPredicate:predicate]; However, matching for the '#' eludes me. I tried constructing a REGEX match using: [NSPredicate predicateWithFormat:@"name matches '[^a-zA-Z].*'"]; But this fails for diacritic-alpha (duplicate rows appear). Any ideas would be greatly appreciated! Thanks.

  • case-insensitive regexp match on non-english text in perl cgi script

    - by jonny
    ok. I have list of catalog paths and need to filter out some of them. Match pattern comes in non-Unicode encoding. Tried following: require 5.004; use POSIX qw(locale_h); my $old_locale = setlocale(LC_ALL); setlocale(LC_ALL, "ru_RU.cp1251"); @{$data -> {doc_folder_rights}} = grep { $_->{doc_folder} =~/$_REQUEST{q}/i; # catalog path pattern in $_REQUEST{q} } @{$data -> {doc_folder_rights}}; setlocale(LC_ALL, $old_locale); What I need is case-insensitive regexp pattern matching when pattern contains russsian letters.

  • Infinite loop in regex in java

    - by carpediem
    Hello, My purpose is to match this kind of different urls: url.com my.url.com my.extended.url.com a.super.extended.url.com and so on... So, I decided to build the regex to have a letter or a number at start and end of the url, and to have a infinite number of "subdomains" with alphanumeric characters and a dot. For example, in "my.extended.url.com", "m" from "my" is the first class of the regex, "m" from "com" is the last class of the regex, and "y.", "extended." and "url." are the second class of the regex. Using the pattern and subject in the code below, I want the find method to return me a false because this url must not match, but it uses 100% of CPU and seems to stay in an infinite loop. String subject = "www.association-belgo-palestinienne-be"; Pattern pattern = Pattern.compile("^[A-Za-z0-9]\\.?([A-Za-z0-9_-]+\\.?)*[A-Za-z0-9]\\.[A-Za-z]{2,6}"); Matcher m = pattern.matcher(subject); System.out.println(" Start"); boolean hasFind = m.find(); System.out.println(" Finish : " + hasFind); Which only prints: Start I can't reproduce the problem using regex testers. Is it normal ? Is the problem coming from my regex ? Could it be due to my Java version (1.6.0_22-b04 / JVM 64 bit 17.1-b03) ? Thanks in advance for helping.

  • How to modularize a JSF/Facelets/Spring application with OSGi?

    - by lexicore
    I'm working with very large JSF/Facelets applications which use Spring for DI/bean management. My applications have modular structure and I'm currently looking for approaches to standardize the modularization. My goal is to compose a web application from a number of modules (possibly depending on each other). Each module may contain the following: Classes; Static resources (images, CSS, scripts); Facelet templates; Managed beans - Spring application contexts, with request, session and application-scoped beans (alternative is JSF managed beans); Servlet API stuff - servlets, filters, listeners (this is optional). What I'd like to avoid (almost at all costs) is the need to copy or extract module resources (like Facelets templates) to the WAR or to extend the web.xml for module's servlets, filters, etc. It must be enough to add the module (JAR, bundle, artifact, ...) to the web application (WEB-INF/lib, bundles, plugins, ...) to extend the web application with this module. Currently I solve this task with a custom modularization solution which is heavily based on using classpath resources: Special resources servlet serves static resources from classpath resources (JARs). Special Facelets resource resolver allows loading Facelet templates from classpath resources. Spring loads application contexts via the pattern classpath*:com/acme/foo/module/applicationContext.xml - this loads application contexts defined in module JARs. Finally, a pair of delegating servlets and filters delegate request processing to the servlets and filters configured in Spring application contexts from modules. Last days I read a lot about OSGi and I was considering, how (and if) I could use OSGi as a standardized modularization approach. I was thinking about how individual tasks could be solved with OSGi: Static resources - OSGi bundles which want to export static resources register a ResourceLoader instances with the bundle context. A central ResourceServlet uses these resource loaders to load resources from bundles. Facelet templates - similar to above, a central ResourceResolver uses services registered by bundles. Managed beans - I have no idea how to use an expression like #{myBean.property} if myBean is defined in one of the bundles. Servlet API stuff - use something like WebExtender/Pax Web to register servlets, filters and so on. My questions are: Am I inventing a bicycle here? Are there standard solutions for that? I've found a mentioning of Spring Slices but could not find much documentation about it. Do you think OSGi is the right technology for the described task? Is my sketch of OSGI application more or less correct? How should managed beans (especially request/session scope) be handled? I'd be generally graefult for your comments.

  • Need to search email body for regex using VBA

    - by user6620
    I am trying to write a script that I can run from a rule withing outlook. The goal of this script is to search the email body for a regex pattern, \d{8}-\d{3}\(E\d\) in this case. I want to take that pattern and see if a folder with the name of the match exists and if not create one. I am not super familiar with VBA as I write mostly in python. I have copied and pasted the following bit of code together but at this time I am unable to get the MsgBox to appear when I send an email with 20120812-001(E3) in the body. I have two different versions below. --version 2-- Sub Filter(Item As Outlook.MailItem) Dim Matches, Match Dim RegEx As New RegExp RegEx.IgnoreCase = True RegEx.Pattern = "\d{8}-\d{3}(E\d)" If RegEx.Test(Item.Body) Then MsgBox "Pattern Detected" End If End Sub --Version 1-- Sub ProcessMessage(myMail As Outlook.MailItem) Dim strID As String Dim objNS As Outlook.NameSpace Dim objMsg As Outlook.MailItem Dim objMatch As Match Dim RetStr As String Set objRegExp = New RegExp objRegExp.Pattern = "\d{8}-\d{3}\(E\d\)" objRegExp.IgnoreCase = True objRegExp.Global = True strID = myMail.EntryID Set objNS = Application.GetNamespace("MAPI") Set objMsg = objNS.GetItemFromID(strID) MsgBox objMsg.Body Set objMatch = objRegExp.Execute(objMsg.Body) MsgBox objMatch End Sub
