  • Preventing Netbeans JAXB generation trashing classes

    - by Mac
    I'm developing a SOAP service using JAX-WS and JAXB under Netbeans 6.8, and getting a little frustrated with Netbeans trashing my work every time the XSD schema my JAXB bindings are based upon changes. To elaborate, the IDE automatically generates classes bound to the schema, which can then be (un)marshalled from/to XML using JAXB. To these classes I've added extra methods to (for example) convert to and from separate classes designed to be persisted to database with JPA. The problem is that whenever the schema changes and I rebuild, these classes are regenerated, and all my custom methods are deleted. I can manually replace them by copy-pasting from a backup file, but that is rather time-consuming and tedious. As I'm using an iterative design approach, the schema is changing rather frequently and I'm wasting an awful lot of time whenever it does, simply to reinstate my previous code. While the IDE automatically regenerating the JAXB-bound classes is entirely reasonable and I don't mean to imply otherwise, I was wondering if anyone had any bright ideas as to how to prevent my extra work having to be manually reinstated every time my schema changes?

  • Restrict access to a specific URL, running on IIS7 / ASP.NET

    - by frankadelic
    I am deploying a public ASP.NET website on an IIS7 web farm. The application runs on 3 web servers and is behind a firewall. We want to create a single page on the website that is accessible only to internal users. It is primarily used for diagnostics, trigger cache expiry, etc. /admin/somepage.aspx What is the best way to control access to this page? We need to: Prevent all external (public) users from accessing the URL. Permit specific internal users to access the page, only from certain IPs or networks. Should this access control be done at the (a) network level, (b) application level, etc.?

  • C# define string format of double/floats to be US english by default

    - by neil
    Hi, I have got several thousands of lines of a web application source code, initially written on a US development system, to maintain. It makes heavy use of SQL statement strings, which are combined on the fly, e.g. string SQL = "select * from table where double_value = " + Math.Round(double_value, 2); Don't comment on bad programming style, that doesn't help me in this case :) The cruix: My system uses a German locale, which in turn leads to wrong SQL statements, like this: "select * from table where double_value = 15,5" (Note the comma as decimal separator instead of a point). Question: What is the most "elegant" way to change the locale of the web app in this case) to US or UK in order to prevent being forced to change and inspect every single line of code? .net 3.5 is not an option (would give me the chance to overwrite ToString() in an extension class) Kind regards

  • How can a hacker put a file on my server root (apache, php, 1and1)

    - by mike-sav
    Hi there, I have a site hosted on 1and1 and a couple of weeks ago I noticed a hacker had put a .php file on the server that when viewed in a browser exposed my DB schema, DB connection strings, FTP account (for file uploads using a form), etc, etc. Naturally I panicked and I wiped the server and reuploaded my files. Fortunatley I encrypt passwords using MD5 and I don't store things like credit card details, etc, etc. Now I checked my files and with all user input I use a clean function (htmlentities, sql_real_escape_string, etc, etc) that strips the input of any XSS or SQL injection. I have also made sure that the session key gets re-engineered when a user status changes (like they log into their account) to prevent session hijacking, my folder permissions are set to 755 and file permission are 644. Has anyone got any idea how this could have happened? Or if I'm missing something

    - by Sephy
    Hi all, I don't know if the title is very clear, but my issue is as follows : I have an activity with a listview, and on top of this listview, i have a searchfield (edittext).

So, is there an attribute or something I can use to prevent this from happening?(I still want to keybord to appear when i click the edittext though...) thank you

  • Programmatically sync the db in Django

    - by Attila Oláh
    I'm trying to sync my db from a view, something like this: from django import http from django.core import management def syncdb(request): management.call_command('syncdb') return http.HttpResponse('Database synced.') The issue is, it will block the dev server by asking for user input from the terminal. How can I pass it the '--noinput' option to prevent asking me anything? I have other ways of marking users as super-user, so there's no need for the user input, but I really need to call syncdb (and flush) programmatically, without logging on to the server via ssh. Any help is appreciated.

  • Any sense to set obj = null(Nothing) in Dispose()?

    - by serhio
    Is there any sense to set custom object to null(Nothing in VB.NET) in the Dispose() method? Could this prevent memory leaks or it's useless?! Let's consider two examples: public class Foo : IDisposable { private Bar bar; // standard custom .NET object public Foo(Bar bar) { this.bar = bar; } public void Dispose() { bar = null; // any sense? } } public class Foo : RichTextBox { // this could be also: GDI+, TCP socket, SQl Connection, other "heavy" object private Bitmap backImage; public Foo(Bitmap backImage) { this.backImage = backImage; } protected override void Dispose(bool disposing) { if (disposing) { backImage = null; // any sense? } } }

  • How should my application keep clients in sync with schema changes to HTML5 databases?

    - by Chad Johnson
    I'm wanting to incorporate HTML5 database storage into my web application to make it online-accessible. I've done lots of development in server-side environments with databases, and we all know that database schema additions and modifications are often necessary. I am wondering what should happen if my application uses an offline database schema, and that schema changes. How do I prevent the application from breaking on the client side? How do I ensure the database is always up to date on the client end? Anyone have any solutions?

  • Preventing symbols from being stripped in IBM Visual Age C/C++ for AIX

    - by smountcastle
    I'm building a shared library which I dynamically load (using dlopen) into my AIX application using IBM's VisualAge C/C++ compiler. Unfortunately, it appears to be stripping out necessary symbols: rtld: 0712-002 fatal error: exiting. rtld: 0712-001 Symbol setVersion__Q2_3CIF17VersionReporterFRCQ2_3std12basic_stringXTcTQ2_3std11char_traitsXTc_TQ2_3std9allocatorXTc__ was referenced from module ./object/AIX-6.1-ppc/plugins/plugin.so(), but a runtime definition of the symbol was not found. Both the shared library and the application which loads the shared library compile/link against the static library which contains the VersionReporter mentioned in the error message. To link the shared library I'm using these options: -bM:SRE -bnoentry -bexpall To link the application, I'm using this option: -brtl Is there an option I can use to prevent this symbol from being stripped in the application? I've tried using -nogc as stated in the IBM docs, but that causes the shared library to be in an invalid format or the application to fail to link (depending on which one I use it with).

  • performance of parameterized queries for different db's

    - by tuinstoel
    A lot of people know that it is important to use parameterized queries to prevent sql injection attacks. Parameterized queries are also much faster in sqlite and oracle when doing online transaction processing because the query optimizer doesn't have to reparse every parameterized sql statement before executing. I've seen sqlite becoming 3 times faster when you use parameterized queries, oracle can become 10 times faster when you use parameterized queries in some extreme cases with a lot of concurrency. How about other db's like mysql, ms sql, db2 and postgresql? Is there an equal difference in performance between parameterized queries and literal queries?

  • Types in Bytecode

    - by HH
    Hey everyone, I've been working for some time on (Java) Bytecode, however, it had never occurred to me to ask why are some instructions typed? I understand that in an ADD operation, we need to distinguish between an integer addition and a FP addition (that's why we have IADD and FADD). However, why do we need to distinguish between ISTORE and FSTORE? They both involve the exact same operation, which is moving 32 bits from the stack to a local variable position? The only answer I can think of is for type-safety, to prevent this: (ILOAD, ILOAD, FADD). However, I believe that type-safety is already enforced at the Java language level. OK, the Class file format is not directly coupled with Java, so is this a way to enforce type-safety for languages that do not support it? Any thought? Thank you.

  • How to limit the number of the same Activity on the stack for an Android application

    - by johnrock
    Is this possible in an Android app? I want to make it so that no matter how many times a user starts activityA, when they hit the back button they will never get more than one occurence of activityA. What I am finding in my current code is that I have only two options: 1. I can call finish() in activityA which will prevent it from being accessible via the back button completely, or 2. I do not call finish(), and then if the user starts activityA (n) times during their usage, there will be (n) instances when hitting the back button. Again, I want to have activityA accessible by hitting the back button, but there is no reason to keep multiple instances of the same activity on the stack. Is there a way to limit the number of instances of an activity in the queue to only 1?

In my example above, those required files being Two.js and Three.js.

  • Is it possible to use HTTPS certificates for licensing?

    - by Ton van den Heuvel
    I am working on an application with multiple clients and a server running various web-services for the clients. To implement licensing I am thinking about using HTTPS as a protocol for the web-services using certificates that are issued by our company. By influencing the expiration date of a certificate for a client we can prevent them from using our software after their license term. It this possible and does it make sense to you? Additional information: I am planning on using Qt/C++ for the clients, and the Twisted framework for the web-services.

  • VSS keep resetting working folder a the root of the C: drive

    - by Alex
    I have noticed several times (that is it does not happens all the time, but occurs regulary) that VSS has forgoten my working folder settings and re-set it to be a root of the C: drive. It is very annoying to find out that some of the files you have checked out and been working on are not in the same folder where you expect them to be (and it also pollutes the drive with a C:\SubProject1, C:\SubProject2 folders instead of keeping them all inside of C:\Work). Any recomendation to prevent VSS from doing this again and again. And yes, please, don't recomment switching to SVN, CVS, TFS etc - there are the rules I can't change.

  • return false for parent javascript function

    - by jeerose
    $("#purchaser_contact").live('submit', function(){ $.ajax({ type: "POST", url: 'ajax/contactSearch.php', data: ({ fname: $("#fname").val(), lname: $("#lname").val(), city: $("#city").val(), state: $("#state").val() }), success: function(d) { var obj = JSON.parse( d ); if(obj.result != 0){ $("#contactSearch").remove(); $("#button-wrapper").before('<div id="contactSearch">' + obj.result + '</div>'); $("#contactSearch").slideToggle('slow'); //return false from submit!! }); }); I know there are other posts on this but I couldn't figure out how to apply them properly to my situation without making it messy. How do I return false on the submit event to prevent the form from submitting if I'm within the $.ajax and success functions? Thanks.

  • Disable Eventlogging for some events using Healthmonitoring

    - by Rody van Sambeek
    I'm using basic healthmonitoring in an ASP.Net website. I'd like to prevent one event with a specific eventcode to appear in the eventlog. All other errors should be logged accordingly. I'd like to accomplish this using plain web.config settings. However I am unable to get it to work. Besides that, using IIS 5 on Windows XP does not write any events to the event log. I can't seem to find out what's wrong, on Windows 2003 it correctly logs the errors. Does anybody have an idea?

  • Search resetting selection in tableview

    - by Jay
    I've got an NSTableView bound to an NSArrayController via content and selection indexes. All great so far - content displayed, etc. Now an NSSearchField is bound to the array controller via filterPredicate and the property of the array content instances that's to be searched. Searching/filtering the table view works great; table view showing only matching entries. However, searching resets the selection on the NSTableView if the existing selection isn't in the search results. Worse, not only during the search but after ending the search there's no selection on the table view. The NSArrayController is set up to Avoid Empty Selection. Any hints on how to properly configure bindings in this scenario to really prevent an empty selection much appreciated!

  • CRSF token and Session replication with Tomcat and Apache

    - by technocool
    I have an J2EE compliant web application. I use a session based token to append a secondary id to all incoming link generated by my application. To prevent my application against CSRF attack, I validate the secondary id before I allow the user session to work off the subsequent page. Recently, while working with session replication mechanism implementation, I observed that on session failover, the generated secodary id is lost and the user get re directed to the login page/default page. Any suggestions on how I can ensure that the my generated secondary token id is not lost from the replicated session?

  • How to verify a digital signature with openssl

    - by Aaron Carlino
    I'm using a thirdparty credit card processing service (Paybox) that, after a successful transaction, redirects back to the website with a signature in the URL as a security measure to prevent people from manipulating data. It's supposed to prove that the request originated from this service. So my success URL looks something like this: /success.php?signature=[HUGE HASH] I have no idea where to start with verifying this signature. This service does provide a public key, and I assume I need to create a private key, but I don't know much beyond that. I'm pretty good with linux, and I know I'll have to run some openssl commands. I'm writing the verification script in PHP, which also has native openssl() functions. If anyone could please push me in the right direction with some pseudo code, or even functional code, I'd be very grateful. Thanks.

  • iPad Video Playback only delivers audio, not visuals.

    - by Dwaine Bailey
    Hi guys, Recently we've developed an iPhone app for an external company, and everything works fine in the app. There is a section where the app pulls video from the client's server, and streams it into the iPhone's MPMoviePlayerController. This works fine on the iPhone and iPodTouch - both the video and the audio show up just great. The problem, however, is that when the app is run on an iPad (using the iPad's iPhone simulator thingo that it does) only the audio plays, and no video can be seen. Does anybody have any suggestions about what may be causing this? I thought perhaps it was the encoding, but then why would this prevent the video from playing on the iPad, and not the iPhone?

  • Impact of Changing IP Address of Outgoing IP Packets From My Network

    - by iamrohitbanga
    If I modify the source ip address of all outgoing ip packets from my network to an ip address belonging to someone else (while ensuring that the checksum is correct) then what will happen. Assume that I have a public IP address connected by a point-to-point link to an ISP. Will the ISP check that the IP address in my IP packets is correct or will it just forward the packets. I believe that ISP should just forward the packets. what mechanisms are present in the Internet that prevent this from happening?

  • Documents/links on preventing HTML form fiddling?

    - by larryq
    Hi everyone, I'm using ASP.Net but my question is a little more general than that. I'm interested in reading about strategies to prevent users from fooling with their HTML form values and links in an attempt to update records that don't belong to them. For instance, if my application dealt with used cars and had links to add/remove inventory, which included as part of the URL the userid, what can I do to intercept attempts to munge the link and put someone else's ID in there? In this limited instance I can always run a check at the server to ensure that userid XYZ actually has rights to car ABC, but I was curious what other strategies are out there to keep the clever at bay. (Doing a checksum of the page, perhaps? Not sure.) Thanks for your input.
