Does Adobe Air work with OpenID/rpxnow?
I'm having a developer build me an AIR app to work with my website so I can have access to desktop photos.
However, my site uses OpenID logins via the rpxnow.com implementation. Works fine in the web version, but my developer has told me that he cannot do rpxnow/openid logins from the AIR app because it doesn't allow pop-ups and/or redirects.
Has anyone found a workaround?

I need to get UTF-8 working in my Java webapp (servlets + JSP, no framework used) to support äöå etc. for regular Finnish text and Cyrillic alphabets like ??? for special cases.
My setup is the following:
Development encironment: Windows XP
Production encironment: Debian
Database used: MySQL 5.x
Users mainly use Firefox2 but also Opera 9.x, FF3, IE7 and Google Chrome are used to access the site.
How to achieve this?
Can anyone can tell me the N-tier Structure used in Web Programming?
Primarily, in 3 tier structure one is presentation layer, another is business logic layer and last is database access layer.
But for N-tier or 4 tier structure what are the layers and what sort of functions do they hold on them? Please explain me with a brief example of each.
Just started with JQuery and I've managed to pass a parameter using POST, firebug confirms this:
Parameters
link [email protected]
Source
link=test1%40test.com
I don't know how to access the link parameter from the receiving page using JQuery, it must be so simple but everything I've been searching through (jquery website, SO, etc) mentions everything but this.
Thanks,
Alex
I am using subsonic simplerepo with migrations in dev and it makes things pretty easy but I keep running into issues with my nvarchar columns that have an index. My users table has an index defined on the username column for obvious reasons but each time I start the project subsonic is doing this:
ALTER TABLE [Users] ALTER COLUMN Username nvarchar(50);
which causes this:
The index 'IX_Username' is dependent on column 'Username'.ALTER TABLE ALTER COLUMN Username failed because one or more objects access this column
Is there any way around this issue?
Is it possible in Android to programmatically send an email using the phone's associated GMail credentials? I can send an email when I explicitly provide the username and password, but I was hoping to leverage the Google account already associated with the phone. Note that I don't need to actually access the username or password; I just want to leverage this information indirectly to send email.

Hi,
I have developed an iPhone app on iphone 3G. How can I test it on iphone 3GS, iPad etc? Is there a service online that lets me access 3GS or iPad remotely?
Thanks.

We have our class libraries on a shared server we access via Samba (and ssh for command line). Sadly, several features seem to fail in both Flex Builder and Flash Builder/Gumbo with this setup. For example, we no longer get automatic syntax and error checking. Anyone familiar with this issue and able to suggest a solution? Thanks!
how can i deny access to call method. something like this
[HandleError]
[Authorize(Roles = "role1, role2")]
public class AdminController : Controller
{
[Deny(Roles = "role2")]
public ActionResult ResultPage(string message)
{
ViewData["message"] = message;
return View();
}
}
I want to access web service in Python or/and Perl scripts. What are the most popular and reliable libraries today?
I read this question, and I know about SOAPpy and ZSI. Can anybody say something about this libraries? Are they reliable enough for use in production?
I am getting a pretty common, "The process cannot access the file because it is being used by another process."
Now I am nearly certain that the only process accessing this file is from code that I have written and I've been careful to use a using statement around accessing it.
But to be 100% sure, is there anyway to check this programatically when this error occurs?
Hi,
I need to change the code of some asp.net application but the application is missing its .cs files, there are only .aspx files. As I read in google, I understand that the application is a precompiled website. I am not too familiar with it so the question is, can I somehow retrieve the code-behind .cs files of this application because I need to change some functions there. Surely there is a way I can access them or retrieve them somehow?
Thanks in advance,
Greg
I want to get the "free memory" of a bunch of servers like this:
def get_mem(servername):
res = os.popen('ssh %s "grep MemFree /proc/meminfo | sed \'s/[^0-9]//g\'"' % servername)
return res.read().strip()
since this can be threaded I want to do something like that:
import threading
thread1 = threading.Thread(target=get_mem, args=("server01", ))
thread1.start()
But now: how can I access the return value(s) of the get_mem functions?
Do I really need to go the full fledged way creating a class MemThread(threading.Thread) and overwriting __init__ and __run__?
How do you access variables which are defined in an included file?
# inc.rb
foo = "bar";
# main.rb
require 'inc.rb'
puts foo
# NameError: undefined local variable or method `foo' for main:Object
The website is running on a web hosting where we don't have access on htaccess file.The web server is Apache. I want to rewrite URL. For example: The original URL:
www.mydomainname.com/en/piecework/piecework.php?piecework_id=11
Expected URL:piecework.mydomainname.com/en/11
How to do it?
This should be really easy. I'm using Quartz running under Apache Tomcat 6.0.18, and I have a jobs.xml file which sets up my scheduled job that runs every minute.
What I would like to do, is if the job is still running when the next trigger time rolls around, I don't want to start a new job, so I can let the old instance complete.
Is there a way to specify this in jobs.xml (prevent concurrent instances)?
If not, is there a way I can share access to an in-memory singleton within my application's Job implementation (is this through the JobExecutionContext?) so I can handle the concurrency myself? (and detect if a previous instance is running)
update: After floundering around in the docs, here's a couple of approaches I am considering, but either don't know how to get them to work, or there are problems.
Use StatefulJob. This prevents concurrent access... but I'm not sure what other side-effects would occur if I use it, also I want to avoid the following situation:
Suppose trigger times would be every minute, i.e. trigger#0 = at time 0, trigger #1 = 60000msec, #2 = 120000, #3 = 180000, etc. and the trigger#0 at time 0 fires my job which takes 130000msec. With a plain Job, this would execute triggers #1 and #2 while job trigger #0 is still running. With a StatefulJob, this would execute triggers #1 and #2 in order, immediately after #0 finishes at 130000. I don't want that, I want #1 and #2 not to run and the next trigger that runs a job should take place at #3 (180000msec). So I still have to do something else with StatefulJob to get it to work the way I want, so I don't see much of an advantage to using it.
Use a TriggerListener to return true from vetoJobExecution().
Although implementing the interface seems straightforward, I have to figure out how to setup one instance of a TriggerListener declaratively. Can't find the docs for the xml file.
Use a static shared thread-safe object (e.g. a semaphore or whatever) owned by my class that implements Job.
I don't like the idea of using singletons via the static keyword under Tomcat/Quartz, not sure if there are side effects. Also I really don't want them to be true singletons, just something that is associated with a particular job definition.
Implement my own Trigger which extends SimpleTrigger and contains shared state that could run its own TriggerListener.
Again, I don't know how to setup the XML file to use this trigger rather than the standard <trigger><simple>...</simple></trigger>.
Hello,
this is my first post here, so I apologize in advance for any stupidity on my side.
I have a service class implemented in Java 6 / Spring 3 that needs an annotation to restrict access by role.
I have defined an annotation called RequiredPermission that has as its value attribute one or more values from an enum called OperationType:
public @interface RequiredPermission {
/**
* One or more {@link OperationType}s that map to the permissions required
* to execute this method.
*
* @return
*/
OperationType[] value();}
public enum OperationType {
TYPE1,
TYPE2;
}
package com.mycompany.myservice;
public interface MyService{
@RequiredPermission(OperationType.TYPE1)
void myMethod( MyParameterObject obj );
}
package com.mycompany.myserviceimpl;
public class MyServiceImpl implements MyService{
public myMethod( MyParameterObject obj ){
// do stuff here
}
}
I also have the following aspect definition:
/**
* Security advice around methods that are annotated with
* {@link RequiredPermission}.
*
* @param pjp
* @param param
* @param requiredPermission
* @return
* @throws Throwable
*/
@Around(value = "execution(public *"
+ " com.mycompany.myserviceimpl.*(..))"
+ " && args(param)" + // parameter object
" && @annotation( requiredPermission )" // permission annotation
, argNames = "param,requiredPermission")
public Object processRequest(final ProceedingJoinPoint pjp,
final MyParameterObject param,
final RequiredPermission requiredPermission) throws Throwable {
if(userService.userHasRoles(param.getUsername(),requiredPermission.values()){
return pjp.proceed();
}else{
throw new SorryButYouAreNotAllowedToDoThatException(
param.getUsername(),requiredPermission.value());
}
}
The parameter object contains a user name and I want to look up the required role for the user before allowing access to the method.
When I put the annotation on the method in MyServiceImpl, everything works just fine, the pointcut is matched and the aspect kicks in. However, I believe the annotation is part of the service contract and should be published with the interface in a separate API package. And obviously, I would not like to put the annotation on both service definition and implementation (DRY).
I know there are cases in Spring AOP where aspects are triggered by annotations one interface methods (e.g. Transactional). Is there a special syntax here or is it just plain impossible out of the box.
PS: I have not posted my spring config, as it seems to be working just fine. And no, those are neither my original class nor method names.
Thanks in advance, Sean
PPS: Actually, here is the relevant part of my spring config:
<aop:aspectj-autoproxy proxy-target-class="false" />
<bean class="com.mycompany.aspect.MyAspect">
<property name="userService" ref="userService" />
</bean>
Is there currently a way to host a shared Git repository in Windows? I understand that you can configure the Git service in Linux with:
git daemon
Is there a native Windows option, short of sharing folders, to host a Git service?
EDIT:
I am currently using the cygwin install of git to store and work with git repositories in Windows, but I would like to take the next step of hosting a repository with a service that can provide access to others.
Hi,
i have two methods
-(void) a {
@synchronized(self) {
// critical section 1
}
}
-(void) b {
@synchronized(self) {
// critical section 2
}
}
now my question is if a thread is in critical section 1. will the critical section 2 be locked for other threads or other threads can access critical section 2.
I have an IIS 6 server hosting a website that is authenticated with NTLM. I would like to turn on anonymous access to most resources, such as css, icons, and javascript. I noticed, using Fiddler, that an NTLM handshake is occuring for all resources pulled from WebResource.axd and other HTTP handlers I am using. How do I turn authentication off on a file that doesn't really exist?
Guys,
Do you know of any tool that would do like Ruby on Rails' Scaffolding (create simple CRUD pages for any particular class to allow quickly populating a database with dummy data), only which used Java classes with Hibernate for database access, and JSP/JSF for the pages?
It is a drag when you are programming one part of an application, but need data that can only be added with another part that is not ready yet, or very cumbersomely by directly inserting it into the DB.
