• Extracting user-friendly exception details in Java

  - by Jon

  I've got a J2EE web application that I'm working on and when an exception occurs, I'd like to get some basic details about the exception and log it. The message that I'm logging should be pretty basic, something that might mean something to the people running the web server(s). Would using e.getMessage() be the best thing to log? Thanks.

• How to generate <a> tag from input fields

  - by NonProgrammer

  Using ASP.Net (in C#), I need to generate a tag that contains person's name, address, etc. I have barely any experience with ASP.NET (or .NET languages) and I am given this assignment. Could someone please guide me to correct path please? Link should look like this: https://example.com/PRR/Info/Login.aspx?SupplierId=36&RegisteredUserLogin=T000001&Mode=RegisteredLoginless&RegisteredModeFunction=AutoShowTotals&RegisteredModeFunction=AutoShowTotals&PayerCountry=FI&[email protected]&ExternalOrderId=1000123&ServiceId=286&Amount286=5000.00&PayerInfo286=T000001|10000123|type1|m&SuccessReturnURL=http://success.html&FailureReturnURL=http://failure.html&SuccessCallbackURL=http://youpay.com/p247/success.html&FailureCallbackURL=http://yourfailure.html following components/fields needs to be sent to API in order to pre-populate information for users: FirstName, LastName, SupplierID = integer, Person's userlogin (Should increment by 1. Example: person 1 = t00001. Person2 = t00002, etc.), PayerCountry, Email, amount For some reason, my management thinks that this is something a non-technical person can do! Any help would be appreciated! Thanks!

• Binding on a port with netpipes/netcat

  - by mindas

  I am trying to write a simple bash script that is listening on a port and responding with a trivial HTTP response. My specific issue is that I am not sure if the port is available and in case of bind failure I fall back to next port until bind succeeds. So far to me the easiest way to achieve this was something like: for (( i=$PORT_BASE; i < $(($PORT_BASE+$PORT_RANGE)); i++ )) do if [ $DEBUG -eq 1 ] ; then echo trying to bind on $i fi /usr/bin/faucet $i --out --daemon echo test 2>/dev/null if [ $? -eq 0 ] ; then #success? port=$i if [ $DEBUG -eq 1 ] ; then echo "bound on port $port" fi break fi done Here I am using faucet from netpipes Ubuntu package. The problem with this is that if I simply print "test" to the output, curl complains about non-standard HTTP response (error code 18). That's fair enough as I don't print HTTP-compatible response. If I replace echo test with echo -ne "HTTP/1.0 200 OK\r\n\r\ntest", curl still complains: user@server:$ faucet 10020 --out --daemon echo -ne "HTTP/1.0 200 OK\r\n\r\ntest" ... user@client:$ curl ip.of.the.server:10020 curl: (56) Failure when receiving data from the peer I think the problem lies in how faucet is printing the response and handling the connection. For example if I do the server side in netcat, curl works fine: user@server:$ echo -ne "HTTP/1.0 200 OK\r\n\r\ntest\r\n" | nc -l 10020 ... user@client:$ curl ip.of.the.server:10020 test user@client:$ I would be more than happy to replace faucet with netcat in my main script, but the problem is that I want to spawn independent server process to be able to run client from the same base shell. faucet has a very handy --daemon parameter as it forks to background and I can use $? (exit status code) to check if bind succeeded. If I was to use netcat for a similar purpose, I would have to fork it using & and $? would not work. Does anybody know why faucet isn't responding correctly in this particular case and/or can suggest a solution to this problem. I am not married neither to faucet nor netcat but would like the solution to be implemented using bash or it's utilities (as opposed to write something in yet another scripting language, such as Perl or Python).

• Unable to fetch Json data from remote url

  - by user3772611

  I am cracking my head to solve this thing. I am unable to fetch the JSON data from remote REST API. I need to fetch the JSOn data nd display the "html_url" field from the JSON data on my website. I saw that you need the below charset and content type for fetching JSON. <html> <head> <meta charset="utf-8"> <meta http-equiv="content-type" content="application/json"> </head> <body> <p>My Instruments page</p> <ul></ul> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script> <script type="text/javascript" src="http://code.jquery.com/jquery-1.11.0.min.js"></script> <script type="text/javascript"> $(document).ready(function () { alert("Inside the script"); $.getJSON(" https://pki.zendesk.com/api/v2/help_center/sections/200268985/articles.json", function (obj) { alert("Inside the getJSON"); $.each(obj, function (key, value) { $("ul").append("<li>" + value.html_url + "</li>"); }); }); }); </script> </body> </html> I referred to following example on jsfiddle http://jsfiddle.net/2xTjf/29/ The "http://date.jsontest.com" given in this example also doesn't work in my code. The first alert is pops but not the other one. I am a novice at JSON/ Jquery. i used jsonlint.com to find if it has valid JSON, it came out valid. I tested using chrome REST client too. What am I missing here ? Help me please ! Thanks in anticipation.

• file_get_contents returns 403 forbidden

  - by absk

  I am trying to make a sitescraper. I made it on my local machine and it works very fine there. When I execute the same on my server, it shows a 403 forbidden error. I am using the PHP Simple HTML DOM Parser. The error I get on the server is this: Warning: file_get_contents(http://example.com/viewProperty.html?id=7715888) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in /home/scraping/simple_html_dom.php on line 40 The line of code triggering it is: $url="http://www.example.com/viewProperty.html?id=".$id; $html=file_get_html($url); I have checked the php.ini on the server and allow_url_fopen is On. Possible solution can be using curl, but I need to know where I am going wrong.

• How do "and" and "or" work when combined in one statement?

  - by orokusaki

  For some reason this function confused me: def protocol(port): return port == "443" and "https://" or "http://" Can somebody explain the order of what's happening behind the scenes to make this work the way it does. I understood it as this until I tried it: Either A) def protocol(port): if port == "443": if bool("https://"): return True elif bool("http://"): return True return False Or B) def protocol(port): if port == "443": return True + "https://" else: return True + "http://" Is this some sort of special case in Python, or am I completely misunderstanding how statements work?

• ASP.NET MVC & Windsor.Castle: working with HttpContext-dependent services

  - by Igor Brejc

  I have several dependency injection services which are dependent on stuff like HTTP context. Right now I'm configuring them as singletons the Windsor container in the Application_Start handler, which is obviously a problem for such services. What is the best way to handle this? I'm considering making them transient and then releasing them after each HTTP request. But what is the best way/place to inject the HTTP context into them? Controller factory or somewhere else?

• Parsing XML elements with dynamic namespace prefix in PHP

  - by BugKiller

  I have the following XML ( you can say SOAP request ) : <SOAPENV:Envelope xmlns:SOAPENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:NS="http://xyz.gov/headerschema" > <SOAPENV:Header> <NS:myHeader> <NS:SourceID>223423</NS:SourceID> </NS:myHeader> </SOAPENV:Header> </SOAPENV:Envelope> I use the following code and it works fine : <?php $myRequest ='<SOAPENV:Envelope xmlns:SOAPENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:NS="http://xyz.gov/headerschema" > <SOAPENV:Header> <NS:myHeader> <NS:SourceID>223423</NS:SourceID> </NS:myHeader> </SOAPENV:Header> </SOAPENV:Envelope>'; $xml = simplexml_load_string($myRequest, NULL, NULL, "http://schemas.xmlsoap.org/soap/envelope/"); $namespaces = $xml->getNameSpaces(true); $soapHeader = $xml->children($namespaces['SOAPENV'])->Header; $myHeader = $soapHeader->children($namespaces['NS'])->myHeader; echo (string)$myHeader->SourceID; ?> The Problem I know the prefix ( SOAPENV + NS ) , but the clients could change the prefix to whatever they want, so they may send me xml document that has ( MY-SOAPENV + MY-NS) prefixes. My Question How can I handle this since the namespace prefixes are not static , how can I parse it ? Thanks

• How can I avoid hard-coding YubiKey user identities into the PAM stack?

  - by CodeGnome

  The Yubico PAM Module seems to require changes to the PAM stack for each user that will be authenticated with a YubiKey. Specifically, it seems that each user's client identity must be added to the right PAM configuration file before the user can be authenticated. While it makes sense to add authorized keys to an authentication database such as /etc/yubikey_mappings or ~/.yubico/authorized_yubikeys, it seems like a bad practice to have to edit the PAM stack itself for each individual user. I would definitely like to avoid having to hard-code user identities into the PAM stack this way. So, is it possible to avoid hard-coding the id parameter to the pam_yubico.so module itself? If not, are there any other PAM modules that can leverage YubiKey authentication without hard-coding the stack?
