  • JSF tags not being rendered as HTML

    - by Toto
    I'm following the Java EE firstcup tutorial using Netbeans and Glassfish. When I execute the JSF web tier I've been instructed to code, the browser gets the same JSF markup coded in the .xhtml file, and the tags are not rendered as HTML tags. I know this by using the view source code in my browser. For example, for this code: <html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html"> <h:head> <title>Page title here</title> </h:head> <h:body> <h2> <h:outputText value="#{bundle.WelcomeMessage}" /> </h2> </h:body> </html> The browser should get something like: <html ...> <head> <title>Page title here</title> </head> <body> <h2> the welcome message goes here </h2> </body> </html> Right? Well, my browser is getting jsf code (the first piece of code above) and not the html code (the second piece of code above). It seems to be a configuration problem in netbeans or glassfish but don't know what. Any ideas? This is my web.xml file: <?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <context-param> <param-name>javax.faces.PROJECT_STAGE</param-name> <param-value>Development</param-value> </context-param> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>/firstcup/*</url-pattern> </servlet-mapping> <session-config> <session-timeout> 30 </session-timeout> </session-config> <welcome-file-list> <welcome-file>greetings.xhtml</welcome-file> </welcome-file-list> </web-app> This is my faces-config.xml file: <?xml version='1.0' encoding='UTF-8'?> <!-- =========== FULL CONFIGURATION FILE ================================== --> <faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"> <application> <resource-bundle> <base-name>firstcup.web.WebMessages</base-name> <var>bundle</var> </resource-bundle> <locale-config> <default-locale>en</default-locale> <supported-locale>es</supported-locale> </locale-config> </application> <navigation-rule> <from-view-id>/greetings.xhtml</from-view-id> <navigation-case> <from-outcome>success</from-outcome> <to-view-id>/response.xhtml</to-view-id> </navigation-case> </navigation-rule> </faces-config> Moreover: The url I'm entering in the browser is http://localhost:8081/firstcup/ but I've also tried: http://localhost:8081/firstcup/greetings.xhtml I've checked Glassfish logs and there's no information about not being able to load FacesServlet

  • SQL Server deadlock issue

    - by George2
    Hello everyone, I am using SQL Server 2008 Enterprise. I am wondering whether dead lock issue is only caused by cross dependencies (e.g. task A has lock on L1 but waits on lock on L2, and at the same time, task B has lock on L2 but waits on lock on L1)? Are there any other reasons and scenarios which will cause deadlock? Are there any other way which will causes dead lock -- e.g. timeout (a S/I/D/U statement do not return for a very long time, and deadlock error will be returned) or can not acquire lock for a long time but not caused by cross-dependencies (e.g. task C needs to get lock on table T, but another task D acquire the lock on table T without releasing the lock, which causes task C not be able to get lock on table T for a long time)? thanks in advance, George

  • Getting Postfix to process the mail queue on Mac OS X

    - by paperclip
    I'm in the process of getting Sendmail/Postfix setup so that I can send and test my PHP scripts when using the mail() function. I've got to the point that when I run the mail() function in PHP, the script executes without any errors and the mail is sent to my mailq but it then does not get processed and simply times-out with a message of: Operation timed out.

  • Can't diagnose my MySQL root user problem

    - by George Crawford
    Hi all, I have a problem with the MySQL root user in My MySQL setup, and I just can't for the life of me work out how to fix it. It seems that I have somehow messed up the root user, and my access to databases is now very erratic. For reference, I'm using MAMP on OS X to provide the MySQL server. I'm not sure how much that matters though - I'd guess that whatever I've done will require a command-line fix to solve it. I can start MySQL using MAMP as usual, and access databases using the 'standard' users I have created for my PHP apps. However, the root user, which I use in my MySQL GUI client, and also in phpMyAdmin, can only access the "information_schema" database, as well as two I have created manually, and presumably (and mistakenly) left permissions wide open for. My 15 or so other databases cannot be accessed my the root user. When I load up phpMyAdmin, the home screen says: "Create new database: No Privileges". I certainly did at some stage change my root user's password using the MAMP dialog. But I don't remember if I did anything else which might have caused this problem. I've tried changing the password again, and there seems to be no change in the issue. I've also tried resetting root password using the command line, including starting mysql manually with --skip-grant-tables then flushing privs, but again, nothing seems to fix the issue. I've come to the end of my ideas, and would very much appreciate some step-by-step advice and diagnosis from one of the experts here! Many thanks for your help.

  • Nginx logic (if cookie set, redirect here...) Is it possible?

    - by Matthew Steiner
    So, I have a pretty basic need, but I can't figure out if it's even possible, much less how to do it. I have a main page that anyone can see. Most of the rest of the application can be seen only if logged in (hence, a "set cookie"). So I was thinking, as long as they don't have a cookie set, they can just see a cached version of nginx. I can get it caching with this: proxy_cache STATIC; proxy_cache_valid 200 1d; proxy_cache_use_stale error timeout invalid_header updating http_500 http_502 http_503 http_504; And it helps a ton. (instead of 15 requests per second it gets over 1000). Now I just need some sort of "server logic" to say only serve the cached page if they have no cookie, otherwise, load the dynamic page (which will automatically redirect them into the app). Any ideas?

  • Compiling Wanderlust for Windows and use it for Gmail.

    - by User1
    I'm trying to get Wanderlust working in Windows to connect to Gmail. Compiling the code is much more painful than expected. Here are the barriers so far: Can't download dependent packages: SEMI, APEL, and FLIM. I eventually found newer versions, but I'm not sure they will work. Anyone have the older versions? Needs make and install. I used MSYS and it seems to have compiled okay. SSL support. I was getting a "Cannot open load file: ssl" error. I found an ssl.el that comes with w3. So installed w3. Bash command in ssl.el: ssl-get-command is running something from /bin/sh (not a directory I have in Windows). I really don't want to refactor this code. Is there a better way? Others speak very highly of Wanderlust, so I want to give it a try. I feel like I'm almost there, but am pretty much worn out with all the crazy configuration I have to do. Does anyone have this working on Windows? I'm pretty sure it will work with Gmail, because of this post. But will it work in Windows too? If you have a few pointers, please help.

  • MS SQL find and replace in TEXT field

    - by incubushead
    I have a database in MS SQL 2005 that was brought up from SQL 2000 and is still using TEXT type fields instead of varchar(max). I need to find and replace a string of characters in the text field but all of the examples of how to do this that I have found don't seem like they would work for me. It seems the UPDATETEXT command requires that the two parameters "insert_offset" and "delete_length" be set explicitly but the string i am searching for could show up in the text at any point or even at several points in the same cell. My understanding of these two parameters is that the string im searching for will always be in the same place, so that insert_offset is the number of spaces into the text that the UPDATETEXT command will start replacing text. Example: Need to find: &lt;u&gt; and Replace it with: <u> Text field example: *Everyone in the room was <b>&lt;u&gt;tired&lt;/u&gt;.</b><br>Then they woke <b>&lt;u&gt;up&lt;/u&gt;. Can anyone help me out with this? THANKS!

  • Special Characters in JS, how to use "/" character

    - by user1461222
    I've vbulletin 4.2.0 i added an special button to it's editor with this article; http://www.vbulletinguru.com/2012/add-a-new-toolbar-button-to-ckeditor-tutorial/ The thing i want to do is add an syntax highlighter code with this button. When i use below code it's working fine; CKEDITOR.plugins.add( 'YourPluginName', { init: function( editor ) { editor.addCommand( 'SayHello', { exec : function( editor ) { editor.insertHtml( "Hello from my plugin" ); } }); editor.ui.addButton( 'YourPluginName', { label: 'My Button Tooltip', command: 'SayHello', icon: this.path + 'YourPluginImage.png' } ); } } ); so i changed this code to this, because i wannt to add specific text like below; CKEDITOR.plugins.add( 'DKODU', { init: function( editor ) { editor.addCommand( 'SayHello', { exec : function( editor ) { editor.insertHtml( '[kod=delphi][/kod]' ); } }); editor.ui.addButton( 'DKODU', { label: 'My Button Tooltip', command: 'SayHello', icon: this.path + 'star.png' } ); } } ); after update the code when i press the button nothings happen, i checked with google and this site but i couldn't figure it out i think i made mistake with some special characters but i couldn't find what's the problem. If i made some mistakes when i publish this question forgive me and also forgive me for my bad english, thanks.

  • Visual Studio WCF Application now asking to manually attach to process

    - by JL
    I have a console app that is calling a WCF app hosted in IIS. Up until now everything has been fine and I am able to debug the app - step through it without any problems... Until I added my dev pc to a domain.... now every time I get step into the code hosted in IIS, a popup comes up asking if I would like to attach to this process... I can then continue debugging... again not a huge train smash - however... now it randomly just jumps to the end of the process (almost like some kind of timeout) and I am not able to reliably step and debug the IIS hosted code.... Any ideas? All the projects are in the same solution, and all running on the local dev pc... Using Visual Studio 2008, dev PC is Win 7

  • Java conditional compilation: how to prevent code chunks to be compiled?

    - by khachik
    My project requires Java 1.6 for compilation and running. Now I have a requirement to make it working with Java 1.5 (from the marketing side). I want to replace method body (return type and arguments remain the same) to make it compiling with Java 1.5 without errors. Details: I have an utility class called OS which encapsulates all OS-specific things. It has a method public static void openFile(java.io.File file) throws java.io.IOException { // open the file using java.awt.Desktop ... } to open files like with double-click (start Windows command or open Mac OS X command equivalent). Since it cannot be compiled with Java 1.5, I want to exclude it during compilation and replace by another method which calls run32dll for Windows or open for Mac OS X using Runtime.exec. Question: How can I do that? Can annotations help here? Note: I use ant, and I can make two java files OS4J5.java and OS4J6.java which will contain the OS class with the desired code for Java 1.5 and 1.6 and copy one of them to OS.java before compiling (or an ugly way - replace the content of OS.java conditionally depending on java version) but I don't want to do that, if there is another way. Elaborating more: in C I could use ifdef, ifndef, in Python there is no compilation and I could check a feature using hasattr or something else, in Common Lisp I could use #+feature. Is there something similar for Java? Found this post but it doesn't seem to be helpful. Any help is greatly appreciated. kh.

  • Qt moc not error

    - by Robert Parker
    So I'm pretty new to Qt, and I've just inherited a project from someone else who is also new to Qt. He isn't around this week btw. We are using Visual Studio 2008, and have the latest version of Qt installed(4.6.2). The project builds on my coworker's machine fine, and I can get the project from svn and build it directly. But under any other circumstances it refuses to build on my machine, and it doesn't give me much of an explanation why. Even if I just do a 'build clean' and then a 'build' it doesn't work. Any slight modification will make it fail. When I try to build the entire project I get the error message: 1Moc'ing MatrixTypeInterface.h... 1moc: Cannot create .\GeneratedFiles\Debug\moc_MatrixTypeInterface.cpp;.\GeneratedFiles\Debug\moc_matrixtypeinterface.cpp 1Project : error PRJ0019: A tool returned an error code from "Moc'ing MatrixTypeInterface.h..." The moc tool doesn't give any sort of error message as to why it isn't working, and I wasted most of yesterday trying to figure out why. I got the command that VS was using to call moc, and I entered in the command line myself. It didn't write anything to the screen. Any ideas?

  • How to make quicksilver remember custom trigger

    - by corroded
    I am trying to make a custom trigger for my shell/apple script file to run so I can just launch my dev environment at the push of a button. So basically: I have a shell script(and some apple script included) in ~ named start_server.sh which does 3 things: start up solr server start up memcached start up script/server I have a saved quicksilver command(.qs) that opens up start_server.sh(so start_server.sh, then the action is "Run in Terminal") I created a custom trigger that calls this saved qs command. I did that then tested it and it works. I then tried to double check it so I quit quicksilver and when I checked the triggers it just said: "Open (null)" as the action. I set the trigger again and when i restarted QS the same thing happened again. I don't know why but my old custom trigger to open terminal has worked since forever so why doesn't this one work? Here's a screenie of the triggers after I restart QS: http://grab.by/4XWW If you have any other suggestion on how to make a "push button" start for my server then please do so :) Thanks! As an added note, I have already tried the steps on this thread but to no avail: http://groups.google.com/group/blacktree-quicksilver/browse_thread/thread/7b65ecf6625f8989

  • RPC Fails but passing in SQL Man. Studios works

    - by Justin
    I am calling a stored procedure from a web service in an ASP.Net application. And until a few days ago, all was well. However now when i call it I get an error saying The timeout period elapsed prior to the completion of the operation or the server could not be reached. However when i would run SQL SERVER PROFILER, I could see that the call was getting to the database, but was timing out. I then copied the statement being executed found at the bottom of the Profiler and pasted it into Management Studio and executed it and it finishes in about 7 seconds.. This runs just fine on our production server. It seems to be similar to this question: SELECT DISTINCT not working in .NET application, but works in SQL Mgmt Studio but I see no answer.

  • Set NTFS Permissions with DirectorySecurity after created Active Dirctory Groups c#

    - by maverick
    Hi I am a little confused about setting NTFS Permissions to a directory after I created Active Directory Groups (both programmatically). When I created the Active Directory Objects then I have to wait a few seconds to set the NTFS Permissions. If I have not this timeout then I get sometimes an error message that the identify (active directory groupname) could not found. Is it possible that the DirectorySecurity-Class from DirectoryInfo-Class has an different algorithm to get the idenfity from active directory objects? Because when I checking the existing of the groups in active directory with System.DirectoryServices all the objects exist suddenly after creation. Kind regards

  • SQL Query - 20mil records - Best practice to return information

    - by eqiz
    I have a SQL database that has the following table: Table: PhoneRecords ID(identity Seed) FirstName LastName PhoneNumber ZipCode Very simple straight forward table. This table has over 20million records. I am looking for the best way to do queries that pull out records based off area codes from the table. For instance here is an example query that I have done. SELECT phonenumber, firstname FROM [PhoneRecords] WHERE (phone LIKE '2012042%') OR (phone LIKE '2012046%') OR (phone LIKE '2012047%') OR (phone LIKE '2012083%') OR (phone LIKE '2012088%') OR (phone LIKE '2012841%') As you can see this is an ugly query, but it would get the job done (if I wasn't running into timeout issues) Can anyone tell me the best way for speed/optimization to do the above query to display the results? Currently that query above takes around 2 hours to complete on a 9gb 1600mhz ram, i7 930 quadcore OC'd 4.01ghz. I obviously have the computer power required to do such a query, but still takes too long for queries.

  • Check if server exists

    - by buhtla
    Here is the problem. User can enter server name and connection string for database. If server is not accessible (wrong address, firewalls or any other issue), I want to be aware of this as quickly as possible. If I'm using sqlConnection and try to connect to a non-accessible server this takes very long (I think more than 1 minute!). This has nothing to do with connection timeout btw so setting this property won't help. My idea is to first try to ping server and if I get response (which means server is accessible from the point of application), than proceed with sqlConnection. If there is no response from ping, operation is aborted and user is properly notified. Is there any better way of doing this? Any idea would be welcome.

  • Perl: How do I capture Chinese input via SCIM with STDIN?

    - by KCArpe
    Hi, I use SCIM on Linux for Chinese and Japanese language input. Unfortunately, when I try to capture input using Perl's STDIN, the input is crazy. As roman characters are typed, SCIM tries to guess the correct final characters. ^H (backspace) codes are used to delete previously suggested chars on the command line. (As you type, SCIM tries to guess final Asian chars and displays them.) However, these backspace chars are shown literally as ^H and not interpreted correctly. Example one-liner: perl -e 'print "Chinese: "; my $s = <STDIN>; print $s' When I enable SCIM Chinese or Japanese language input, as I type, e.g., nihao = ??, here is the result: ?^H?^H?^H?^H?^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H??^H^H?? At the very end of this string, you can see "??" (nihao/hello). At a normal bash prompt, if I type nihao (with Chinese enabled), the results is perfect. This has something to do with interpretation of backspace chars (or control chars) during Perl's STDIN. The same thing happens when using command 'read' in Bash. Witness: read -p 'Chinese: ' s && echo $s Cheers, Kevin

  • In Mercurial, can I apply changes from one file to another file in the same branch?

    - by Stephen
    In the good old days of Subversion, I would sometimes derive a new file from an existing one using svn copy. Then if something changed in sections they had in common, I could still use svn merge to update the derived version. To use the example from hginit.com, say the "guac" recipe already exists, and I want to create a "superguac" that includes instructions on how to serve guacamole to 1000 raving soccer fans. Using the process I just described, I could: svn cp guac superguac svn ci -m "Created superguac by copying guac" (edit superguac) svn ci -m "Added instructions for serving 1000 raving soccer fans to superguac" (edit guac) svn ci -m "Fixed a typo in guac" svn merge -r3:4 guac superguac and thus the typo fix would be applied to superguac. Mercurial provides an hg copy command that marks a file as a copy of the original, but I'm not sure the repository structure supports a similar workflow. Here's the same example, and I carefully only edit a single file in the commit I want to use in the merge: hg cp guac superguac hg ci -m "Created superguac by copying guac" (edit superguac) hg ci -m "Added instructions for serving 1000 raving soccer fans to superguac" (edit guac) hg ci -m "Fixed a typo in guac" I now want to apply the change in guac to superguac. Is that possible? If so, what's the right command? Is there a different workflow in Mercurial that achieves the same results (limited to a single branch)?

  • How can I selectively override a django .count() method

    - by Tom Viner
    I'm using postGresSQL and my main table has about 20,000 rows. Sometimes count() methods can take ages or even timeout. Mod.manager.filter(...).count() I need to selectively override the count() method depending on what filter has been applied. Just having a cache of results would be a great gain but I'd like to be able to say: if filter query is just {'enabled'=True} then return 20,000 without touching the db. Note: I can't prevent the call to .count() as it's inside django's pagination, which always does a count.

  • Invert the 1bbp color under a rectangle.

    - by Scott Chamberlain
    I am working with GDI+, the image I am working with is a 1bbp image. What i would like to do is draw a rectangle on the image and everything under that rectangle will be inverted (white pixels will become black and black pixels become white). All of the sample code I have seen is for 8 bit RGB color scale images, and I don't think the techniques they use will work for me. Here is the code I have so far. This is the parent control, one of the Epl2.IDrawableCommand's will be the command that does the inverting. protected override void OnPaint(PaintEventArgs e) { base.OnPaint(e); if (Label != null) { using (Bitmap drawnLabel = new Bitmap((int)((float)Label.LabelHeight * _ImageScaleFactor), (int)((float)Label.LableLength *(int) _ImageScaleFactor), System.Drawing.Imaging.PixelFormat.Format1bppIndexed)) { using (Graphics drawBuffer = Graphics.FromImage(drawnLabel)) { drawBuffer.ScaleTransform(_ImageScaleFactor, _ImageScaleFactor); foreach (Epl2.IDrawableCommand cmd in Label.Collection) { cmd.Paint(drawBuffer); } drawBuffer.ResetTransform(); } drawnLabel.RotateFlip(Rotation); pbLabelDrawArea.Size = drawnLabel.Size; using (Graphics drawArea = pbLabelDrawArea.CreateGraphics()) { drawArea.Clear(Color.White); drawArea.DrawImage(drawnLabel, new Point(0, 0)); } } } } What should I put in the Paint(Graphic g) for this command?

  • How to execute stored procedure from Access using linked tables

    I have an Access 2003 database that connects to a SQL Server 2008 box via ODBC. The tables from SQL Server are connected as linked tables in Access. I have a stored procedure on the SQL Server that I am trying to execute via ADO code. The problem I have is that Access cannot seem to find the procedure. What do I have to do within Access to be able to execute this stored procedure? Some facts ... The stored procedure in question accepts one parameter which is an integer.

  • Exporting database from external server (without SSH access)

    - by Derek Carlisle
    Our current website is hosted by the design agency who originally built the website, however we are bringing the development of the website in house therefore need to export the database from their server and import it to ours. We have FTP and phpMyAdmin access but don't have SSH access to the server. I was hoping to run a PHP script that would mysql dump the database, compress it and then copy it across to our server using scp: $backupFile = $_SERVER['DOCUMENT_ROOT'].'/backup' . date("Y-m-d-H-i-s") . '.gz'; system("mysqldump -h DB_HOST -u DB_USER -pDB_PASS DB_NAME | gzip > $backupFile"); exec("sshpass -p PASSWORD scp -r -P PORT_NUMBER $backupFile [email protected]:/path/to/directory/"); I have ran this locally from the command line and it worked fine, although I had to install sshpass (the hosting server might not have this installed). Also, I was hoping to run it from the browser as I don't have command line access on the hosting server, however it didn't work, no errors produced though. Can you anyone recommend how I can export from the server that I don't have SSH access to and import to my server? Thanks

  • [C#] Two System.Drawing methods manifest slow drawing or flickery: Solutions? or Other Options?

    - by Luke Mcneice
    Hi all, I am doing a little graphing via the System.Drawing and im having a few problems. I'm holding data in a Queue and i'm drawing(graphing) out that data onto three picture boxes this method fills the picture box then scrolls the graph across. so not to draw on top of the previous drawings (and graduly looking messier) i found 2 solutions to draw the graph. Call plot.Clear(BACKGOUNDCOLOR) before the draw loop [block commented] although this causes a flicker to appear from the time it takes to do the actual drawing loop. call plot.DrawLine(channelPen[5], j, 140, j, 0); just before each drawline [commented] although this causes the drawing to start ok then slow down very quickly to a crawl as if a wait command had been placed before the draw command. Here is the Code for reference: /*plotx.Clear(BACKGOUNDCOLOR) ploty.Clear(BACKGOUNDCOLOR) plotz.Clear(BACKGOUNDCOLOR)*/ for (int j = 1; j < 599; j++) { if (j > RealTimeBuffer.Count - 1) break; QueueEntity past = RealTimeBuffer.ElementAt(j - 1); QueueEntity current = RealTimeBuffer.ElementAt(j); if (j == 1) { //plotx.DrawLine(channelPen[5], 0, 140, 0, 0); //ploty.DrawLine(channelPen[5], 0, 140, 0, 0); //plotz.DrawLine(channelPen[5], 0, 140, 0, 0); } //plotx.DrawLine(channelPen[5], j, 140, j, 0); plotx.DrawLine(channelPen[0], j - 1, (((past.accdata.X - 0x7FFF) / 256) + 64), j, (((current.accdata.X - 0x7FFF) / 256) + 64)); //ploty.DrawLine(channelPen[5], j, 140, j, 0); ploty.DrawLine(channelPen[1], j - 1, (((past.accdata.Y - 0x7FFF) / 256) + 64), j, (((current.accdata.Y - 0x7FFF) / 256) + 64)); //plotz.DrawLine(markerPen, j, 140, j, 0); plotz.DrawLine(channelPen[2], j - 1, (((past.accdata.Z - 0x7FFF) / 256) + 94), j, (((current.accdata.Z - 0x7FFF) / 256) + 94)); } Is there any tricks to avoid these overheads? If not would there be any other/better solutions?

  • use Ghostscript to convert pcl to postscript

    - by Bryon
    So I want to use Ghostscript to convert files that are created in pcl format to postscript. That's the gist of my problem. I am simply trying to run it on the command line, but in the final stage it will have to be run on a lp command like lp -d < gs something something GPL Ghostscript 9.00 (2010-09-14) I will be running this on a solaris 10 server but I believe any unix system should work similar. bash-3.00# /usr/local/bin/gs -sDEVICE=pswrite -dLanguageLevel=1 -dNOPAUSE -dBATCH -dSAFER -sOutputFile=output.ps cms-form.pcl GPL Ghostscript 9.00 (2010-09-14) Copyright (C) 2010 Artifex Software, Inc.
