  • How can I serve static content with Glassfish embedded?

    - by Andy Fiedler
    I'm trying to setup Glassfish embedded with a WAR project that implements a REST API and then some static Javascript content that calls it. I got the WAR to deploy and the REST API is available with a context root of "/Users". How can I use Glassfish to serve static content with a context root of "/". So for example, if the user requests http://myserver.com/Users/some-REST-call it routes to the WAR application and http://myserver.com/somefile.js serves a static file from some directory? Here's my Main class file so far: public class Main{ public static void main(String[] args) throws Exception { String port = System.getenv("PORT"); port = port != null ? port : "8080"; GlassFishProperties gfProps = new GlassFishProperties(); gfProps.setPort("http-listener", Integer.parseInt(port)); GlassFish glassfish = GlassFishRuntime.bootstrap().newGlassFish(gfProps); glassfish.start(); Deployer deployer = glassfish.getDeployer(); deployer.deploy(new File("target/Users-Rest.war")); } } Thanks a ton for your help!

  • Is the following valid XHTML 1.0 Transitional?

    - by willem
    The w3c validator service complains that the following html is invalid. It does not like the ampersand(&) in my javascript. But ampersands are allowed in javascript strings, aren't they? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Page Title</title> </head> <body> <script type="text/javascript"> function search(query) { redir = "http://search.mysite.com/search?s=FIN&ref=&q=" + query; window.location.href = redir return false; } </script> <span>This is all valid HTML</span> </body> </html>

  • [solved] IE6 PNG-transparency CSS hack not working

    - by John
    I looked around and decided to use a CSS approach rather than rely on JS... I figure the kind of corporate users stuck with IE6 might also have JS disabled by IT departments. So In my HTML I have: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> <title>My Page</title> <link rel="stylesheet" type="text/css" href="default.css" /> <!--[if IE 6]><link rel="stylesheet" type="text/css" href="ie6.css"><![endif]--> </head> <body> <img src="media/logo.png"/> </body> Then my ie6.css consists simply of: img { filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(...); } However none of this makes the slightest difference, no transparency. I commented out all the rest of the page so it is literally that one and still no luck. I removed the default.css stylesheet and still no difference. EDIT: I now got it working, using the .htc method, loading that file in a conditional IE6 test block. It turned out the problem I was having was that Windows 7 had 'locked' the file (I don't even know what this means) and this blocked IE from loading/using it.

  • facebook graph api does not return all feed items on facebook page

    - by Nick Franceschina
    at the time of this question, if you go here: http://www.facebook.com/realplayer you'll see six posts down, I have posted a photo with a message of "#highfive Cincinnati, OH" but if you to either of these: http://graph.facebook.com/realplayer/feed http://graph.facebook.com/realplayer/tagged the JSON that is returned seemingly includes everything on the wall, except for MY post. there is another photo post from someone else down below mine, and it is showing up (and both my photo and his photo are in the "Fan photos" section) obviously, since I can see everything with these links already, it appears that access_token is not a part of the equation... BUT, some more info: if I use an access_token from a session that isn't me, I can't see the post in the JSON if I use an access_token from MY logged in session, then I DO see the post in the JSON so I'm very confused. if everyone in the world can see those posts on the wall without even authenticating, then I expect all of them to come back in the graph api as well. anyone have thoughts on this? I am aware of the "manage_page" permission... which I can use to get a list of accounts and special offline access tokens for those pages... and that's something I can explore... but it seems like alot of work when my post seemingly SHOULD be there in the graph

  • VS2010 - Using <Import /> to share properties between setup projects?

  • Some sonatype nexus questions.

    - by smallufo
    I deployed a sonatype nexus server inside my LAN , mapping some remote repositories to my public repositories : First question is , why these repositories not sync with the "real" repositories ? For example , I mapped maven central (http://repo1.maven.org/maven2) to "central" , but when I browse http://smallufo:8081/nexus/content/repositories/central/org/springframework/ , the packages are not complete , in http://repo2.maven.org/maven2/org/springframework/ , there are tons of artifacts , but I only have some of them : And versions are old ... ex : spring-core is only 2.5.6.SEC01 , but the latest version is 3.0.2.RELEASE. And my maven client seems can only find the old artifacts ... "central" is a proxy directory , it should be the same with the remote server. I tried to "Expire Cache" , "ReIndex" , "Incremental ReIndex" the whole "central" : After a long time with almost 100% java process load , the situation seems not better , just add some artifacts ... not reflecting the real "Maven Central" data... Second question , what's difference with "Expire Cache" , "ReIndex" , "Incremental ReIndex" ? Even I can "search" spring-core.3.0.2.RELEASE , my m2eclipse still cannot find it : I can also see the spring-core-3.0.2.RELEASE in the "index" , (but not available in "storage") : But why m2eclipse cannot make use of it ? it seems m2eclipse can only install artifacts in the storage , if this is how nexus works , how do I "force" download spring-core-3.0.2.RELEASE to nexus's storage ? How do I solve these strange incompatibilities ? Thanks a lot !

  • Calling web service from seems to hang

    - by anothershrubery
    I am trying to call an asmx web service from an Android app. Just literally started some Android development today. I've been following various solutions I have found on the net and on here and it seems it is more difficult than anticipated. I have tried various solutions and using KSoap2 seems to be the easiest way to implement this, well it would be if I could get it working. I have the following code which works up until a point: private class CallWebService extends AsyncTask<Void, Void, Void> { private static final String SOAP_ACTION = "http://tempuri.org/GetUser"; private static final String METHOD_NAME = "GetUser"; private static final String NAMESPACE = "http://tempuri.org/"; private static final String URL = "http://160.10.1.79:59315/Service1.asmx"; TextView tv; @Override protected Void doInBackground(Void... params) { tv=(TextView)findViewById(R.id.txtMessage); try { SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.dotNet=true; envelope.setOutputSoapObject(request); HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); androidHttpTransport.call(SOAP_ACTION, envelope); Object result = (Object)envelope.getResponse(); tv.setText(result.toString()); } catch (Exception e) { tv.setText(e.getMessage()); } return null; } } It seems to hang at the line androidHttpTransport.call(SOAP_ACTION, envelope); Any ideas why? Is this the correct approach? Should I be looking in another direction?

  • Masonry js won't bunch images vertically

    The images are being aligned horizontally correctly but they are all spaced out vertically.. Take a look here http://brstudios.co.uk/testing to see what I mean properly.. My mark up is as followed (simplified): <html> <head> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript" src="http://masonry.desandro.com/jquery.masonry.min.js"></script> <script type="text/javascript" src="https://raw.github.com/desandro/imagesloaded/master/jquery.imagesloaded.min.js"></script> <script type="text/javascript"> var $container = $('.portfolio-container'); $container.imagesLoaded(function(){ $container.masonry({ itemSelector : '.break', columnWidth : 429 }); }); </script> <style type="text/css"> .break { float: left; width: 429px; margin: 10px 20px; } </style> </head> <body> <div class="portfolio-container"> <?php do { ?> <div class="break"> // Contents taken from MySQL // </div> <?php } while ($row_displayPosts = mysql_fetch_assoc($displayPosts)); ?> </div> </body> </html> I think part of it is working but as you can see by the link provided it isn't moving the elements together vertically. Does anyone have any pointers?

  • overwrite parameters passed by querystring

    - by opensas
    I have the following problem I have a web framework built with classic asp that saves the page state in hidden textboxes, and then issues a submit to itself. Before submitting, we have a javascript functions that saves the action in a hidden "action" input, and then performs the submit. The page loads the state from those hidden texts, reads the action issued, reads extra parameters, like the id of the record to edit, and then builds the page accordingly. I'd like to make a url link to automatically start the page with "edit" action on a "x" id. So I was thinking about building the following url, for example http://myapp/user?action=edit&id=23 the problem is that when the page auto-submits, que url string keeps the parameters. I'd like to achieve the following: when the user clicks on http://myapp/user?action=edit&id=23 my page should receive the posted values action=edit and id=23 but the url should be just http://myapp/user and both parameters should be kept in the hidden texts... (I wonder if I make myself clear...) thanks a lot saludos sas ps: I have a couple of ideas about how to solve it, but I'll post them as answers...

Can you not call a function unless it was defined inside the OnCreate? I get a nullPointer Exception when calling the function.

  • YouTube API, jQuery attr won't swap element attributes (I think) in IE, but works in FF

    - by Anthony
    JavaScript (jQuery) function display_youtube(new_url) { $('#movie_url').removeAttr('value'); $('#embed_url').removeAttr('src'); $(document).ready(function() { $('#movie_url').attr('value', new_url); $('#embed_url').attr('src', new_url); $('#shade').css('display', 'block'); $('#youtube_player').css('display', 'block'); $('#exit_youtube').css('display', 'block'); }); } HTML <object width="720" height="480"> <param id="movie_url" name="movie" value="http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=0" /> <param name="allowFullScreen" value="true" /> <param name="allowscriptaccess" value="always" /> <embed id="embed_url" src="http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="720" height="480" /> </object> Hyperlink <a href="javascript:display_youtube('http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=1');">Click Here for Fun!</a> What I've done is parsed YouTube's API for the videos on my user channel. The hyperlink above is php generated, meant to trigger the above JavaScript function, and swap the url from attributes contained in ids "movie_url" and "embed_url". Works just like it should in FF, but IE will only perform the .css commands. My guess? IE doesn't like me assigning IDs to PARAM and EMBED, perhaps? What do you think?

  • Uploading multiple files asynchronously by blueimp jquery-fileupload

    - by Ryo
    I'm using jQuery File Upload library (http://github.com/blueimp/jQuery-File-Upload), and I've been stuck figuring out how to use the library satisfying the following conditions. The page has multiple file input fields surrounded by a form tag. Users can attach multiple files to each input field All files are sent to a server when the button is clicked, not when files are attached to the input fields. Upload is done asynchronously Say the page has 3 input fields with their name attributes being "file1[]", "file2[]" and "file3[]", the request payload should be like {file1: [ array of files on file1[] ], file2: [ array of files on file2[] ], ...} Here's jsFiddle, it's behaving weird so far in that it sends post request twice and the first one is cancelled. http://jsfiddle.net/BAQtG/24/ The core part of js code looks like this. $(document).ready(function(){ var filesList = [] var elem = $("form") file_upload = elem.fileupload({ formData:{extra:1}, autoUpload: false, fileInput: $("input:file"), }).on("fileuploadadd", function(e, data){ filesList.push(data.files[0]) }); $("button").click(function(){ file_upload.fileupload('send', {files:filesList} ) }) }) Anybody have idea how to get this to work? Updates Now thanks to @CBroe 's comment, the issue that request is sent twice is fixed. However the keys of request parameter is not correctly set. Here's updated jsFiddle. http://jsfiddle.net/BAQtG/27/

  • Can Win32_NetworkAdapterConfiguration.EnableStatic() be used to set more than one IP address?

    - by Andrew J. Brehm
    I ran into this problem in a Visual Basic program that uses WMI but could confirm it in PowerShell. Apparently the EnableStatic() method can only be used to set one IP address, despite taking two parameters IP address(es) and subnetmask(s) that are arrays. I.e. $a=get-wmiobject win32_networkadapterconfiguration -computername myserver This gets me an array of all network adapters on "myserver". After selecting a specific one ($a=$a[14] in this case), I can run $a.EnableStatic() which has this signature System.Management.ManagementBaseObject EnableStatic(System.String[] IPAddress, System.String[] SubnetMask) I thought this implies that I could set several IP addresses like this: $ips="192.168.1.42","192.168.1.43" $a.EnableStatic($ips,"255.255.255.0") But this call fails. However, this call works: $a.EnableStatic($ips[0],"255.255.255.0") It looks to me as if EnableStatic() really takes two strings rather than two arrays of strings as parameters. In Visual Basic it's more complicated and arrays must be passed but the method appears to take into account only the first element of each array. Am I confused again or is there some logic here?

  • Send file FTP over SSL with custom port number

    - by JM4
    I have asked the question before but in a different manner. I am trying taking form data, compiling into a temporary CSV file and trying to send over to a client via FTP over SSL (this is the only route I am interested in hearing solutions for unless there is a workaround to doing this, I cannot make changes). I have tried the following: ftp_connect - nothing happens, the page just times out ftp_ssl_connect - nothing happens, the page just times out curl library - same thing, given URL it also gives error. I am given the following information: FTPS Server IP Address TCP Port (1234) Username Password Data Directory to dump file FTP Mode: Passive very, very basic code (which I believe should initiate a connection at minimum): Code: <?php $ftp_server = "00.000.00.000"; //masked for security $ftp_port = "1234"; // masked but not 990 $ftp_user_name = "username"; $ftp_user_pass = "password"; // set up basic ssl connection $conn_id = ftp_ssl_connect($ftp_server, $ftp_port, "20"); // login with username and password $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); echo ftp_pwd($conn_id); // / echo "hello"; // close the ssl connection ftp_close($conn_id); ?> When I run this over a SmartFTP client, everything works just fine. I just can't get it to work using PHP (which is a necessity). Has anybody had success doing this in the past? I would be very interested to hear your approach.

  • is concatenating the only way to 'import' one JS lib from another?

    - by Nikita
    Disclaimer: JS novice I have a JS widget that depends on JQuery. The widget's going to be embedded in a 3rd party site but I figure out how to avoid declaring dependency on jquery on the widget-hosting page: 3rd party's page: <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js"></script> <script type="text/javascript" src="http://mydomain/mywidget.js"></script> </head> mywidget.js jQuery(document).ready(function() { //do stuff }); I'd rather not include jquery.js in the 3d party page but express the dependency inside mywidget.js (so i can change this dependency or add/remove others w/o having to update the widget-hosting page) I tried adding: var script = document.createElement('script'); script.src = 'http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.js'; script.type = 'text/javascript'; document.getElementsByTagName('head')[0].appendChild(script); to the top of mywidget.js but that didn't work - jquery.js did load on page load but "jQuery" was not recognized. What did work was concatenating jquery.js and mywidget.js into a single .js file. But that seems kind of lame - is there no equivalent to? import com.jquery.*; thanks!

  • Eliminate full table scan due to BETWEEN (and GROUP BY)

    - by Dave Jarvis
    Description According to the explain command, there is a range that is causing a query to perform a full table scan (160k rows). How do I keep the range condition and reduce the scanning? I expect the culprit to be: Y.YEAR BETWEEN 1900 AND 2009 AND Code Here is the code that has the range condition (the STATION_DISTRICT is likely superfluous). SELECT COUNT(1) as MEASUREMENTS, AVG(D.AMOUNT) as AMOUNT, Y.YEAR as YEAR, MAKEDATE(Y.YEAR,1) as AMOUNT_DATE FROM CITY C, STATION S, STATION_DISTRICT SD, YEAR_REF Y FORCE INDEX(YEAR_IDX), MONTH_REF M, DAILY D WHERE -- For a specific city ... -- C.ID = 10663 AND -- Find all the stations within a specific unit radius ... -- 6371.009 * SQRT( POW(RADIANS(C.LATITUDE_DECIMAL - S.LATITUDE_DECIMAL), 2) + (COS(RADIANS(C.LATITUDE_DECIMAL + S.LATITUDE_DECIMAL) / 2) * POW(RADIANS(C.LONGITUDE_DECIMAL - S.LONGITUDE_DECIMAL), 2)) ) <= 50 AND -- Get the station district identification for the matching station. -- S.STATION_DISTRICT_ID = SD.ID AND -- Gather all known years for that station ... -- Y.STATION_DISTRICT_ID = SD.ID AND -- The data before 1900 is shaky; insufficient after 2009. -- Y.YEAR BETWEEN 1900 AND 2009 AND -- Filtered by all known months ... -- M.YEAR_REF_ID = Y.ID AND -- Whittled down by category ... -- M.CATEGORY_ID = '003' AND -- Into the valid daily climate data. -- M.ID = D.MONTH_REF_ID AND D.DAILY_FLAG_ID <> 'M' GROUP BY Y.YEAR Update The SQL is performing a full table scan, which results in MySQL performing a "copy to tmp table", as shown here: +----+-------------+-------+--------+-----------------------------------+--------------+---------+-------------------------------+--------+-------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+-------+--------+-----------------------------------+--------------+---------+-------------------------------+--------+-------------+ | 1 | SIMPLE | C | const | PRIMARY | PRIMARY | 4 | const | 1 | | | 1 | SIMPLE | Y | range | YEAR_IDX | YEAR_IDX | 4 | NULL | 160422 | Using where | | 1 | SIMPLE | SD | eq_ref | PRIMARY | PRIMARY | 4 | climate.Y.STATION_DISTRICT_ID | 1 | Using index | | 1 | SIMPLE | S | eq_ref | PRIMARY | PRIMARY | 4 | climate.SD.ID | 1 | Using where | | 1 | SIMPLE | M | ref | PRIMARY,YEAR_REF_IDX,CATEGORY_IDX | YEAR_REF_IDX | 8 | climate.Y.ID | 54 | Using where | | 1 | SIMPLE | D | ref | INDEX | INDEX | 8 | climate.M.ID | 11 | Using where | +----+-------------+-------+--------+-----------------------------------+--------------+---------+-------------------------------+--------+-------------+ Related http://dev.mysql.com/doc/refman/5.0/en/how-to-avoid-table-scan.html http://dev.mysql.com/doc/refman/5.0/en/where-optimizations.html http://stackoverflow.com/questions/557425/optimize-sql-that-uses-between-clause Thank you!

  • authorise user from mysql database

    I suck at php, and cant find the error here. The script gets 2 variables "username" and "password" from a html from then check them against a MySQL databse. When I run this I get the follow error "Query was empty" <? if ((!$_POST[username]) || (!$_POST[password])) { header("Location: show_login.html"); exit; } $db_name = "testDB"; $table_name = "auth_users"; $connection = @mysql_connect("localhost", "admin", "pass") or die(mysql_error()); $db = @mysql_select_db($db_name, $connection) or die(mysql_error()); $slq = "SELECT * FROM $table_name WHERE username ='$_POST[username]' AND password = password('$_POST[password]')"; $result = @mysql_query($sql, $connection) or die(mysql_error()); $num = mysql_num_rows($result); if ($num != 0) { $msg = "<p>Congratulations, you're authorised!</p>"; } else { header("Location: show_login.html"); exit; } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Secret Area</title> </head> <body> <? echo "$msg"; ?> </body> </html>

  • Goldbach theory in C

    - by nofe
    I want to write some code which takes any positive, even number (greater than 2) and gives me the smallest pair of primes that sum up to this number. I need this program to handle any integer up to 9 digits long. My aim is to make something that looks like this: Please enter a positive even integer ( greater than 2 ) : 10 The first primes adding : 3+7=10. Please enter a positive even integer ( greater than 2 ) : 160 The first primes adding : 3+157=160. Please enter a positive even integer ( greater than 2 ) : 18456 The first primes adding : 5+18451=18456. I don't want to use any library besides stdio.h. I don't want to use arrays, strings, or anything besides for the most basic toolbox: scanf, printf, for, while, do-while, if, else if, break, continue, and the basic operators (<,, ==, =+, !=, %, *, /, etc...). Please no other functions especially is_prime. I know how to limit the input to my needs so that it loops until given a valid entry. So now I'm trying to figure out the algorithm. I thought of starting a while loop like something like this: #include <stdio.h> long first, second, sum, goldbach, min; long a,b,i,k; //indices int main (){ while (1){ printf("Please enter a positive integer :\n"); scanf("%ld",&goldbach); if ((goldbach>2)&&((goldbach%2)==0)) break; else printf("Wrong input, "); } while (sum!=goldbach){ for (a=3;a<goldbach;a=(a+2)) for (i=2;(goldbach-a)%i;i++) first = a; for (b=5;b<goldbach;b=(b+2)) for (k=2;(goldbach-b)%k;k++) sum = first + second; } }
