• Why is this mod_rewrite RewriteRule directive not working in the .htaccess file?

  - by morgant

  I've got a site that was hosted on a linux el cheapo hosting service that I'm migrating to my Mac OS X 10.5 Leopard Server server running Apache 2.2.8 & PHP 5.2.5 w/rewrite_module enabled and AllowOverride All, but I'm running into an issue with the following lines in the .htaccess file: RewriteEngine On #RewriteRule ^view/([^/\.]+)/?$ /view.php?item=$1 [L] #RewriteRule ^order/([^/\.]+)/?$ /order.php?item=$1 [L] RewriteRule ^category/([^/\.]+)/?$ /category.php?category=$1 [L] As you can see, I've commented out the RewriteRule directives for /view/ and /order/, so I'm only dealing with /category/. When I attempt to load http://domain.tld/category/2/ it runs category.php (I've added debug code to confirm), but $_SERVER['REQUEST_URI'] comes through as /category/2/ and $_GET['category'] comes through as empty. I'm usually fine with troubleshooting .htaccess files and mod_rewrite directives, but this one's got me stumped for some reason. Update: I followed Josh's suggestion and here's the what's dumped to mod_rewrite.log when I try to access http://domain.tld/category/2/: 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (2) init rewrite engine with requested uri /category/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) applying pattern '.*' to uri '/category/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (1) pass through /category/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] add path info postfix: /Library/WebServer/Documents/tld.domain.www/category.php -> /Library/WebServer/Documents/tld.domain.www/category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/category.php/13 -> category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri 'category.php/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6aa98/subreq] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/category.php 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] add path info postfix: /Library/WebServer/Documents/tld.domain.www/category.php -> /Library/WebServer/Documents/tld.domain.www/category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/category.php/13 -> category.php/13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri 'category.php/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b5ea98/initial] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/category.php 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (2) init rewrite engine with requested uri /13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) applying pattern '.*' to uri '/13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (1) pass through /13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] strip per-dir prefix: /Library/WebServer/Documents/tld.domain.www/13 -> 13 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (3) [perdir /Library/WebServer/Documents/tld.domain.www/] applying pattern '^category/([^/\.]+)/?$' to uri '13' 65.19.81.253 - - [22/Oct/2009:17:31:53 --0400] [domain.tld/sid#100aae0b0][rid#100b6ea98/subreq] (1) [perdir /Library/WebServer/Documents/tld.domain.www/] pass through /Library/WebServer/Documents/tld.domain.www/13

• Notes on Oracle BPM PS6 Adaptive Case Management

  - by gcolman

  v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} I have recently been looking at the  latest release of the BPM Case Management feature in the Oracle BPM PS6 release. I had put together some notes to help me gain a better understanding of the context of the PS6 BPM Case Management. Hopefully, this along with the other resources will enable you to gain a clear picture of the flexibility of this feature. Oracle BPM PS6 release includes Case Management capability. This initial release aims to provide: Case Management Framework Integration of Case Management with BPM & SOA suite It is best to regard the current PS6 case management feature as a case management framework. The framework provides the building blocks for creating a case management system that is fully integrated into Oracle BPM suite. As of the current PS6 release, no UI tooling exists to help manage cases or the case lifecycle. Mark Foster has written a good blog which outlines Case Management within PS6 in the following link. I wanted to provide more context on Case Management from my perspective in this blog. PS6 Case Management - High level View BPM PS6 includes “Case” as a first class component in a SOA Suite composite. The Case components (added to the SOA Composite) are created when a BPM process is assigned to a case in JDveloper. The SOA Case component is defined and configured within JDevloper, which allows us to specify the case data structures and metadata such as stakeholders, outcomes, milestones, document stores etc. "Activities" are associated with a case, and become available to be executed via the case apis. Activities are BPM processes, Human Activities or Java call outs. The PS6 release includes some additional database tables to store the case metadata and case instance data (data object, comments, etc…). These new tables are created within the SOA_INFRA schema and the documents associated with that case into a document repository that is configured with the case. One of the main features of Case Management is the control of the case logic through case events and case business rules. A PS6 Case has an associated business rule component, which can be configured to control the availability and execution of activities within the case. The business rules component is able to act upon events that the PS6 Case Management framework generates during the lifecycle of that case. Events are fired during the lifetime of the case (e.g. Case created, activity started, activity ended, note added, document uploaded.) Internal Case state The internal state of a case is represented by the diagram below. This shows the internal states and the transition paths for a Case from one state to the next Each transition in state will create an event that can be enacted upon via the Case rules engine. The internal case state lifecycle is defined as follows Defining a case A Case is created and defined as a component of a JDeveloper BPM project. When you create a Case as part of a BPM project, JDeveloper, creates the following components within the SCA composite: Case component Case component interfaces (WSDL etc) Case Rules component (Oracle Business Rules) Adds the Case Component and Case Rules Component to the BPM SOA composite Case Configuration The following section gives a high level overview of the items that can be configured for a BPM Case. Case Activities A Case is associated with a set of activities that are to be performed as part of that Case. Case activities can be: SOA Human Tasks BPM processes Custom Task (Java Class) Case activities are created from pre-existing BPM process or human tasks, which, once defined, can be configured additionally as Case activities in JDeveloper and made available within the lifecycle of a case. I've described the following configurable components of a case (very!) briefly as: Milestones Milestones are (optional) user defined logical milestones that can be achieved within a case. No activities are associates with a milestone, but milestone attainment can be programmatically set and events raised when milestones are reached Outcomes User defined status of a completed case. An event is fired when an outcome is attained. Case Data Defines the data that will be stored with a case XML schemas define the data that is stored with the case. Case Documents Defines the location of documents that are attached to a case (e.g. WebCenter Content) User Defined Events Optional user defined events that can be fired or captured to drive case processing rules Stakeholders Defines the actors who can participate in the case (roles, users, groups) Defines permissions for individual case permissions (read case, create document etc…) Business Rules Business rules are the main component controlling the flow of a Case Each case has an associated business ruleset Rules are fired on receiving Case events (or User defined events) Life cycle events Milestone events Activity events Data events Document events Comment events User event Managing the Case Managing the lifecycle of a case is achieved in two ways: Managing case logic with Business Rules Managing the case lifecycle via the Case APIs. A BPM Case can be viewed as a set of case data & documents along with the activities that can be performed within a case and also the case lifecycle state expressed as milestones and internal lifecycle state. The management of the case life is achieved though both the configuration of business rules and the “manual” interaction with a case instance through the Case APIs. Business Rules and Case Events A key component within the Case management framework is the event model. The BPM Case Management solution internally utilizes Oracle EDN (Event Delivery Network) to publish and subscribe to events generated by the Case framework. Events are generated by the Case framework on each of the processes and stages that a case instance will travel on its lifetime. The following case events are part of the BPM Case: Life cycle events Milestone events Activity events Data events Document events Comment events User event The Case business rules are configured to listen for these events, and business logic can be coded into the Case rules component to enact upon an event being received. Case API & Interaction Along with the business rules component, Cases can be managed via the Case API interfaces. These interfaces allow for the building of custom applications to integrate into case management framework. The API’s allow for updating case comments & documents, executing case activities, updating milestones etc. As there is no in built case management UI functions within the PS6 release, Cases need to be managed via a custom built UI, interacting with selected case instances, launching case activities, closing cases etc. (There is expected to be a UI component within subsequent releases) Logical Case Flow The diagram below is intended to depict a logical view of the case steps for a typical case. A UI or other service calls the Case interface to create a Case instance The case instance is created & database data inserted A lifecycle event is raised indicating a case activity (created) event The case business rules capture the event and decide on an action to take Additionally other parties can subscribe to Case events via EDN The business rules may handle the event, e.g. configured to execute a case activity on case creation event The BPM/Human Workflow/Custom activity is executed A case activity event is raised on the execute activity A case work UI or business service can inspect the case instance and call other actions to progress that case, such as: Execute activity Add Note Add document Add case data Update Milestone Raise user defined event Suspend case Resume case Close Case Summary Having had a little time to play around with the APIs and the case configuration, I really like the flexibility and power of combining Oracle Business Rules and the BPM Case Management event model. Creating something this flexible and powerful without BPM Case Management would take a lot of time and effort. This is hopefully going to save my customers a lot of time and effort! I may make amendments to this post as my understanding of Case Management increases! Take a look at the following links for official documentation etc. http://docs.oracle.com/cd/E28280_01/doc.1111/e15176/case_mgmt_bpmpd.htm https://blogs.oracle.com/bpm/entry/just_in_case Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Calibri","sans-serif";}

• Connecting HDMI MediaCenter PC to Standard Def TV

  - by Adam

  I just purchased a ASRock ION 330-HT-BD to use as my new Media Center. Sadly I still have a crappy standard-def old tube TV for the foreseeable future. The TV has Coax & Composite (Red, White, Yellow) inputs, and my new MediaCenterr has HDMI & VGA outputs. So my question is, how do I hook up the two together! All of the HDMI-to-Composite cables I have found explicitly state that they can not be used to hook a PC up to a TV. Any ideas?

• Convert a gray PNG with alpha to a 1-bit black rectanble with 8-bit alpha

  - by jcayzac

  I use a tool to render LaTeX equations as PNG. The resulting images are in RGBA8888 format. I would like to extract the luminance (grayscale from RGB channels, multiplied by the A channel) as my new alpha channel, set the picture fully black, and save the result in Gray1Alpha8 (G1A8) format. So far I've only managed to get G1A4 or G8A8 but not G1A8. Also, the resulting picture looks like it's not multiplied correctly… convert original.png \ \( -clone 0 -alpha extract \) \ \( -clone 0 -clone 1 -compose multiply -composite \) \ -delete 0 +swap -alpha off -compose copy_opacity -composite -colorspace Gray -depth 4 result.png What am I missing?

• Architecture Standards &ndash; BPMN vs. BPEL for Business Process Management

  - by pat.shepherd

  I get asked often which business process standard an organization should use; BPMN or BPEL?  As I explain to folks, they both have strengths.  Here is a great article that helps understand the benefits of both and where to use them.  The good news is that, with Oracle SOA Suite and BPM suite, you have the option and flexibility to use both in the same SCA model and runtime container.  Good stuff. Here is the great article that Mark Nelson wrote: The right tool for the right job BPEL and BPMN are both ‘languages’ or ‘notations’ for describing and executing business processes. Both are open standards. Most business process engines will support one or the other of these languages. Oracle however has chosen to support both and treat them as equals. This means that you have the freedom to choose which language to use on a process by process basis. And you can freely mix and match, even within a single composite. (A composite is the deployment unit in an SCA environment.) So why support both? Well it turns out that BPEL is really well suited to modeling some kinds of processes and BPMN is really well suited to modeling other kinds of processes. Of course there is a pretty significant overlap where either will do a great job What BPM adds to SOA Suite | RedStack

• Unable to extend desktop

  - by CSharperWithJava

  I'm trying to hook up my TV to my computer as a gaming/multimedia center but I'm having troubles setting it up. I have a custom built machine running Windows 7 RC. It has an ATI Radeon 4800 video card with 2 dvi output and 1 S-video output. I have an s-video to composite adapter that connects to my tv. (It's an old TV with only Cable, composite, and s-video connections). I can switch the desktop to my TV without a problem, but I can't duplicate or extend my desktop onto it. I've installed the latest drivers and Catalyst Control Center, but it won't let it work any more readily than Windows would. Any suggestions? Would using an s-video cable instead of the adapter change anything? (The only reason I use the adapter is because it came with the graphics card) (Edit) I installed the latest drivers and I can now duplicate the screen (show on one monitor and on the TV), but I still can't extend the desktop.

• How to draw an E-R diagram?

  - by Appy

  I am learning DBMS in my college. Recently I was given an assignment to draw a E-R Model of a Bus Reservation system which handles Reservations, Ticketing and cancellations. I understand the theory about E-R model when I study from a book, but it gets confusing when I try to draw one from scratch. How should one proceed? There seem to be a lot of ways to model a E-R diagram for a particular requirement. It's really confusing. Can anyone explain taking Bus reservation System as an example? Here is the model I made (But I am not confident with it because at every step, I could think of many more alternatives!) - Entity_Set Passenger(passengerID,name,age,gender) Entity_Set Ticket(ticketID,status) //Status is either WaitingList , Confirmed or Cancelled Entity_Set Bus (busID,MaxSeats,Type) //Type is Ac or Non-AC Entity_Set Route(routeID,ArrivalTime,DepartureTime,Source,Destination) And a Ternary relationship between Passenger, Ticket and Bus with attributes as passengerID, ticketID, busID . Binary relationship between Bus and Route with attributes as busID, routeID . I have few doubts regarding - 1 . Should we take Time as a composite attribute with Arrival and Departure as its attributes (What's the difference if we take that way?) 2 . The same with Source and Destination. Should they be made into a composite attribute "Place" or something like "Location"? 3. Are there any weak entity sets here? Can you please 'create' a weak entity set and explain? Because I have no idea at all what to take as a Weak entity set?

• Unable to extend desktop

  - by CSharperWithJava

  I'm trying to hook up my TV to my computer as a gaming/multimedia center but I'm having troubles setting it up. I have a custom built machine running Windows 7 RC. It has an ATI Radeon 4800 video card with 2 dvi output and 1 S-video output. I have an s-video to composite adapter that connects to my tv. (It's an old TV with only Cable, composite, and s-video connections). I can switch the desktop to my TV without a problem, but I can't duplicate or extend my desktop onto it. I've installed the latest drivers and Catalyst Control Center, but it won't let it work any more readily than Windows would. Any suggestions? Would using an s-video cable instead of the adapter change anything? (The only reason I use the adapter is because it came with the graphics card) (Edit) I installed the latest drivers and I can now duplicate the screen (show on one monitor and on the TV), but I still can't extend the desktop.

• "Input not Supported" on external monitor

  - by Shalan

  when it rains, it pours! Im helping a friend with his Dell Inspiron 1520. The hdd crashed and and top of that, the screen is cracked. I've replaced the hdd (SATA-5400), but the lcd replacement is only comin in a months time. I've tried to: hook the laptop up to an Acer 18.5" lcd monitor via VGA, boot up into Windows 7 installer, get to the Step-1 screen, Switch to external display (Function-F8) ...and get the "Input not supported" message on the Acer lcd. I know that this is a resolution problem, but cant for the life of me figure out how to solve this. I've also tried, hooking it up to my TV via Composite cables (got a VGA-Composite adaptor). Please could someone advise me what to do? -Thank u!

• How do I improve picture quality while streaming live football (soccer) from my Dell D600 to an HDTV?

  - by Bob

  I have fibre broadband with speeds up to 38mbs, my Dell D600 has its max 2gb ram and has an ATI Mobility RADEON 9000 4xAGP 32mb card in it...Its TV support it says is NTSC or PAL in S-video and composite modes with a 7-pin mini-DIN connector (optional S-video to composite video adapter cable) and a vga port which i am using at the moment... The laptop runs Windows XP, an 80g HD with only windows + necessary updates and anti virus software on it..... There is HDMI on the TV, but not the laptop Fairly slow moving and close up pictures arent too bad, but when the movment is fast(a shot on goal) or in the distance, I cant see the ball and the images go out of focus.

• Which are the best ways to organize view hierarchies in GUI interfaces?

  - by none

  I'm currently trying to figure out the best techniques for organizing GUI view hierarchies, that is dividing a window into several panels which are in turn divided into other components. I've given a look to the Composite Design Pattern, but I don't know if I can find better alternatives, so I'd appreciate to know if using the Composite is a good idea, or it would be better looking for some other techniques. I'm currently developing in Java Swing, but I don't think that the framework or the language can have a great impact on this. Any help will be appreciated. ---------EDIT------------ I was currently developing a frame containing three labels, one button and a text field. At the button pressed, the content inside the text field would be searched, and the results written inside the three labels. One of my typical structure would be the following: MainWindow | Main panel | Panel with text field and labels. | Panel with search button Now, as the title explains, I was looking for a suitable way of organizing both the MainPanel and the other two panels. But here came problems, since I'm not sure whether organizing them like attributes or storing inside some data structure (i.e. LinkedList or something like this). Anyway, I don't really think that both my solution are really good, so I'm wondering if there are really better approaches for facing this kind of problems. Hope it helps

• Is this an acceptable UI design decision?

  - by DVK

  OK, while I'm on record as stating that StackExchange UI is pretty much one of the best websites and overall GUIs that I have ever seen as far as usability goes, there's one particular aspect of the trilogy that bugs me. For an example, head on to http://meta.stackoverflow.com . Look at the banner on top (the one that says "reminder -- it's April Fool's Day depending on your time zone!"). Personally, I feel that this is a "make the user do the figuring out work" anti-pattern (whatever it's officially called) - namely, instead of making your app smart enough to only present a certain mode of operations in the conditions when that mode is appropriate, you simply turn on the mode full on and put an explanation to the user of why the mode is on when it should not be (in this particular example, the mode is of course displaying the unicorn gravatars starting with 00:00 in the first timezone, despite the fact that some users still live in March 31st). The Great Recalc was also handled the same way - instead of proactively telling the user "your rep was changed from X to Y" the same nearly invisible banner was displayed on meta. So, the questions are: Is there such an official anti-pattern, and if so,m what the heck do i call it? Do you have any other well-known examples of such design anti-pattern? How would you fix either the SO example I made or you your own example? Is there a pattern of fixing or must it be a case-by-case solution?

• sitemesh vs jsp-config (<include-prelude>)

  - by Nrj

  Please help clarifying : In web.xml I have the following <jsp-config> <jsp-property-group> <url-pattern>*.jsp</url-pattern> <el-ignored>false</el-ignored> <page-encoding>utf-8</page-encoding> <include-prelude>/jstlTaglibs.jspf</include-prelude> </jsp-property-group> </jsp-config> Also in decorators.xml I have <decorator name="footer" page="footer.jsp"> <pattern>*.action</pattern> </decorator> which is used via sitemesh.xml. The footer.jsp which says ... <decorator:body /> <@include .. "footer.jsp"/> So what I gather is, both of the codes above in a sense inject some jspf. Please help highlighting the differences and benefits of both the approaches. Also which one is more used across industry ?

• Looking for input on GWT / MVP action w/o browser history change

  - by user198313

  Hello there, I am trying to develop a GWT app with the MVP pattern. So far so good except for one specific case of actions: actions that do not change the url (no browser history change). In the GWT MVP pattern, events are sent from presenters, the an app controller catches them and update the browser history. If the history has changed then the view updates. ** MVP with history change (Works well)** Current URL is /list User clicks on contactdelete button. Fire DeleteContactAction event. App controller catches, change history to 'delete' onValueChange is called if (token.equals("delete")) delete contact screen, then delete contact Fire ContactDeletedEvent app controller catches and change the history to list onValueChange is called: contact list refreshes GWT MVP pattern for dialog box w/o history changes ** Issue ** - I use a dialog box and I don't want to change the browser history, so here is the problem: Current URL is /list User clicks on contactdelete button. Contact is deleted Fire ContactDeletedEvent. App controller catches, change history to 'list' **onValueChange is NOT called** because url is already /list and there is no change # problem: contact list does not refresh Question: does anyone know a pattern to implement this in the context of MVP? Any help / idea appreciated.

• Spring HandlerInterceptor or Spring Security to protect resource

  - by richever

  I've got a basic Spring Security 3 set up using my own login page. My configuration is below. I have the login and sign up page accessible to all as well as most everything else. I'm new to Spring Security and understand that if a user is trying to access a protected resource they will be taken to the defined login page. And upon successful login they are taken to some other page, home in my case. I want to keep the latter behavior; however, I'd like specify that if a user tries to access certain resources they are taken to the sign up page, not the login page. Currently, in my annotated controllers I check the security context to see if the user is logged in and if not I redirect them to the sign up page. I only do this currently with two urls and no others. This seemed redundant so I tried creating a HandlerInterceptor to redirect for these requests but realized that with annotations, you can't specify specific requests to be handled - they all are. So I'm wondering if there is some way to implement this type of specific url handling in Spring Security, or is going the HandlerInterceptor route my only option? Thanks! <http auto-config="true" use-expressions="true"> <intercept-url pattern="/login*" access="permitAll"/> <intercept-url pattern="/signup*" access="permitAll"/> <intercept-url pattern="/static/**" filters="none" /> <intercept-url pattern="/" access="permitAll"/> <form-login login-page="/login" default-target-url="/home"/> <logout logout-success-url="/home"/> <anonymous/> <remember-me/> </http>

• Spring Security 3.0 - Intercept-URL - All pages require authentication but one

  - by gav

  Hi All, I want any user to be able to submit their name to a volunteer form but only administrators to be able to view any other URL. Unfortunately I don't seem to be able to get this correct. My resources.xml are as follows; <?xml version="1.0" encoding="UTF-8"?> <beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd"> <http realm = "BumBumTrain Personnel list requires you to login" auto-config="true" use-expressions="true"> <http-basic/> <intercept-url pattern="/person/volunteer*" access=""/> <intercept-url pattern="/**" access="isAuthenticated()" /> </http> <authentication-manager alias="authenticationManager"> <authentication-provider> <user-service> <user name="admin" password="admin" authorities="ROLE_ADMIN"/> </user-service> </authentication-provider> </authentication-manager> </beans:beans> Specifically I am trying to achieve the access settings I described via; <intercept-url pattern="/person/volunteer*" access=""/> <intercept-url pattern="/**" access="isAuthenticated()" /> Could someone please describe how to use intercept-url to achieve the outcome I've described?

• Is a red-black tree my ideal data structure?

  - by Hugo van der Sanden

  I have a collection of items (big rationals) that I'll be processing. In each case, processing will consist of removing the smallest item in the collection, doing some work, and then adding 0-2 new items (which will always be larger than the removed item). The collection will be initialised with one item, and work will continue until it is empty. I'm not sure what size the collection is likely to reach, but I'd expect in the range 1M-100M items. I will not need to locate any item other than the smallest. I'm currently planning to use a red-black tree, possibly tweaked to keep a pointer to the smallest item. However I've never used one before, and I'm unsure whether my pattern of use fits its characteristics well. 1) Is there a danger the pattern of deletion from the left + random insertion will affect performance, eg by requiring a significantly higher number of rotations than random deletion would? Or will delete and insert operations still be O(log n) with this pattern of use? 2) Would some other data structure give me better performance, either because of the deletion pattern or taking advantage of the fact I only ever need to find the smallest item? Update: glad I asked, the binary heap is clearly a better solution for this case, and as promised turned out to be very easy to implement. Hugo

• EOL Special Char not matching

  - by Aurélien Ribon

  Hello, I am trying to find every "a - b, c, d" pattern in an input string. The pattern I am using is the following : "^[ \t]*(\\w+)[ \t]*->[ \t]*(\\w+)((?:,[ \t]*\\w+)*)$" This pattern is a C# pattern, the "\t" refers to a tabulation (its a single escaped litteral, intepreted by the .NET String API), the "\w" refers to the well know regex litteral predefined class, double escaped to be interpreted as a "\w" by the .NET STring API, and then as a "WORD CLASS" by the .NET Regex API. The input is : a -> b b -> c c -> d The function is : private void ParseAndBuildGraph(String input) { MatchCollection mc = Regex.Matches(input, "^[ \t]*(\\w+)[ \t]*->[ \t]*(\\w+)((?:,[ \t]*\\w+)*)$", RegexOptions.Multiline); foreach (Match m in mc) { Debug.WriteLine(m.Value); } } The output is : c -> d Actually, there is a problem with the line ending "$" special char. If I insert a "\r" before "$", it works, but I thought "$" would match any line termination (with the Multiline option), especially a \r\n in a Windows environment. Is it not the case ?

• Java JSP/Servlet: controller servlet throwing the famous stack overflow

  - by NoozNooz42

  I've read several docs and I don't get it: I know I'm doing something wrong but I don't understand what. I've got a website that is entirely dynamically generated: there's hardly any static content at all. So, trying to understand JSP/Servlet, I've written my own "front controller" intercepting every single query, it looks like this: <servlet-mapping> <servlet-name>defaultservlet</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> Basically I want any user request, like: example.org example.org/bar example.org/foo.html to all go through a default servlet which I've written. The servlet then examines the URI and find to which .jsp the request must be dispatched, and then does, after having set all the attributes correctly, a: RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/WEB-INF/jsp/index.jsp"); dispatcher.forward(req, resp); When I'm using a url-pattern (in web.xml) like, say, *.html, everything works fine. But when I change it to /* (to really intercept everything), I enter an endless loop and it ends up with a... StackOverflow :) When the request is dispatched, is the URI ".../WEB-INF/jsp/index.jsp" itself matched by the web.xml filter /* that I set? How should I do if I want to intercept everything using a /* url-pattern and yet be able to dispatch/forward/? I'm not asking about specs/Javadocs here: I'm really confused about the bigger picture and I'd need some explanation as to what could be going on. Am I not supposed to intercept really everything? If I can intercept everything, what should I be aware of regarding forwarding/dispatching?

• Replace apostrophe in json string with empty string

  - by user572844

  Hi, I have problem with deserialization of json string, because string is bad format. For example json object consist string property statusMessage with value "Hello "dog" ". The correct format should be "Hello \" dog \" " . I would like remove apostrophes from this property. Something Like this. "Hello "dog" ". - "Hello dog ". Here is it original json string which I work. "{\"jancl\":{\"idUser\":18438201,\"nick\":\"JANCl\",\"photo\":\"1\",\"sex\":1,\"photoAlbums\":1,\"videoAlbums\":0,\"sefNick\":\"jancl\",\"profilPercent\":75,\"emphasis\":false,\"age\":\"-\",\"isBlocked\":false,\"PHOTO\":{\"normal\":\"http://u.aimg.sk/fotky/1843/82/n_18438201.jpg?v=1\",\"medium\":\"http://u.aimg.sk/fotky/1843/82/m_18438201.jpg?v=1\",\"24x24\":\"http://u.aimg.sk/fotky/1843/82/s_18438201.jpg?v=1\"},\"PLUS\":{\"active\":false,\"activeTo\":\"0000-00-00\"},\"LOCATION\":{\"idRegion\":\"6\",\"regionName\":\"Trenciansky kraj\",\"idCity\":\"138\",\"cityName\":\"Trencianske Teplice\"},\"STATUS\":{\"isLoged\":true,\"isChating\":false,\"idChat\":0,\"roomName\":\"\",\"lastLogin\":1294925369},\"PROJECT_STATUS\":{\"photoAlbums\":1,\"photoAlbumsFavs\":0,\"videoAlbums\":0,\"videoAlbumsFavs\":0,\"videoAlbumsExts\":0,\"blogPosts\":0,\"emailNew\":0,\"postaNew\":0,\"clubInvitations\":0,\"dashboardItems\":1},\"STATUS_MESSAGE\":{\"statusMessage\":\"\"Status\"\",\"addTime\":\"1294872330\"},\"isFriend\":false,\"isIamFriend\":false}}" Problem is here, json string consist this object: "STATUS_MESSAGE": {"statusMessage":" "some "bad" value" ", "addTime" :"1294872330"} Condition of string which I want modified: string start with "statusMessage":" string can has any *lenght from 0 -N * string end with ", "addTime So I try write pattern for string which start with "statusMessage":", has any lenght and is ended with ", "addTime. Here is it: const string pattern = " \" statusMessage \" : \" .*? \",\"addTime\" "; var regex = new Regex(pattern, RegexOptions.IgnoreCase); //here i would replace " with empty string string result = regex.Replace(jsonString, match => ???); But I think pattern is wrong, also I don’t know how replace apostrophe with empty string (remove apostrophne). My goal is : "statusMessage":" "some "bad" value" to "statusMessage":" "some bad value" Thank for advice

• How do I apply a "template" or "skeleton" of code in C# here?

  - by Scott Stafford

  In my business layer, I need many, many methods that follow the pattern: public BusinessClass PropertyName { get { if (this.m_LocallyCachedValue == null) { if (this.Record == null) { this.m_LocallyCachedValue = new BusinessClass( this.Database, this.PropertyId); } else { this.m_LocallyCachedValue = new BusinessClass( this.Database, this.Record.ForeignKeyName); } } return this.m_LocallyCachedValue; } } I am still learning C#, and I'm trying to figure out the best way to write this pattern once and add methods to each business layer class that follow this pattern with the proper types and variable names substituted. BusinessClass is a typename that must be substituted, and PropertyName, PropertyId, ForeignKeyName, and m_LocallyCachedValue are all variables that should be substituted for. Are attributes usable here? Do I need reflection? How do I write the skeleton I provided in one place and then just write a line or two containing the substitution parameters and get the pattern to propagate itself? EDIT: Modified my misleading title -- I am hoping to find a solution that doesn't involve code generation or copy/paste techniques, and rather to be able to write the skeleton of the code once in a base class in some form and have it be "instantiated" into lots of subclasses as the accessor for various properties. EDIT: Here is my solution, as suggested but left unimplemented by the chosen answerer. // I'll write many of these... public BusinessClass PropertyName { get { return GetSingleRelation(ref this.m_LocallyCachedValue, this.PropertyId, "ForeignKeyName"); } } // That all call this. public TBusinessClass GetSingleRelation<TBusinessClass>( ref TBusinessClass cachedField, int fieldId, string contextFieldName) { if (cachedField == null) { if (this.Record == null) { ConstructorInfo ci = typeof(TBusinessClass).GetConstructor( new Type[] { this.Database.GetType(), typeof(int) }); cachedField = (TBusinessClass)ci.Invoke( new object[] { this.Database, fieldId }); } else { var obj = this.Record.GetType().GetProperty(objName).GetValue( this.Record, null); ConstructorInfo ci = typeof(TBusinessClass).GetConstructor( new Type[] { this.Database.GetType(), obj.GetType()}); cachedField = (TBusinessClass)ci.Invoke( new object[] { this.Database, obj }); } } return cachedField; }

• Regular expression either/or not matching everything

  - by dwatransit

  I'm trying to parse an HTTP GET request to determine if the url contains any of a number of file types. If it does, I want to capture the entire request. There is something I don't understand about ORing. The following regular expression only captures part of it, and only if .flv is the first int the list of ORd values. (I've obscured the urls with spaces because Stackoverflow limits hyperlinks) regex: GET.?(.flv)|(.mp4)|(.avi).? test text: GET http: // foo.server.com/download/0/37/3000016511/.flv?mt=video/xy match output: GET http: // foo.server.com/download/0/37/3000016511/.flv I don't understand why the .*? at the end of the regex isnt callowing it to capture the entire text. If I get rid of the ORing of file types, then it works. Here is the test code in case my explanation doesn't make sense: public static void main(String[] args) { // TODO Auto-generated method stub String sourcestring = "GET http: // foo.server.com/download/0/37/3000016511/.flv?mt=video/xy"; Pattern re = Pattern.compile("GET .?\.flv."); // this works //output: // [0][0] = GET http :// foo.server.com/download/0/37/3000016511/.flv?mt=video/xy // the match from the following ends with the ".flv", not the entire url. // also it only works if .flv is the first of the 3 ORd options //Pattern re = Pattern.compile("GET .?(\.flv)|(\.mp4)|(\.avi).?"); // output: //[0][0] = GET http: // foo.server.com/download/0/37/3000016511/.flv // [0][1] = .flv // [0][2] = null // [0][3] = null Matcher m = re.matcher(sourcestring); int mIdx = 0; while (m.find()){ for( int groupIdx = 0; groupIdx < m.groupCount()+1; groupIdx++ ){ System.out.println( "[" + mIdx + "][" + groupIdx + "] = " + m.group(groupIdx)); } mIdx++; } } }
