• How to structure well my adwords campaign?

  - by Romain Dorange

  I am starting an adwords campaigns and I will measure conversion rates using the Adwords conversion tracking pixel. Conversion might be account creation or a concrete sale. As it will be a test campaign to have some insights on CTR, CR, etc... on the future, I am likely to try several configurations. two differents ads with different landing URL and messages : one with a focus on the product / the other will contains a discount embedded in the URL 4 differents groups/thematics of keywords I guess I have to build 4 ads groups based on the keywords 2 ads with the different messages assign the two ads to each ads groups follow the campaign precisely in the ads tabs where I can see the effectiveness of each Ads per Ads Groups (for a total of 8 lines of reporting) Am I right ? Also, what are the KPI I can have from an adwords campaign tu measure global effectiveness? measure of ROI from concrete sales (tracking pixel with e-commerce tag on confirmation page) measure of ROI from leads acquisition (tracking pixel on account creation) measure of traffic increase with the campaign Thanks a lot.

• Is having a class have a handleAction(type) method bad practice?

  - by zhenka

  My web application became a little too complicated to do everything in a controller so I had to build large wrapper classes for ORM models. The possible actions a user can trigger are all similar and after a certain point I realized that the best way to go would be to just have constructor method receive action type as a parameter to take care of the small differences internally, as opposed to either passing many arguments or doing a lot of things in the controller. Is this a good practice? I can't really give details for privacy issues.

• LDAP: Need login of application/servers from a certain group only

  - by Geo

  We need to configure LDAP for login to different servers and applications. We have created all users and different groups as follows: dn: dc=ldapserver,dc=local dn: ou=people,dc=ldapserver,dc=local ou: people dn: uid=geo,ou=people,dc=ldapserver,dc=local dn: uid=user,ou=people,dc=ldapserver,dc=local dn: ou=groups,dc=ldapserver,dc=local dn: cn=server,ou=groups,dc=ldapserver,dc=local member: uid=geo,ou=people,dc=ldapserver,dc=local dn: cn=website,ou=groups,dc=ldapserver,dc=local member: uid=user,ou=people,dc=ldapserver,dc=local We need scenario in such a way that the users that are member of server need only login to server (that is geo) and users that are member of website need only login to websites (That is user “user”). Please let me know how we can configure it. For login site we tried by giving DN as cn=website,ou=groups,dc=ldapserver,dc=local and Login Attribute as uid and also member but it is not working. Can anyone please help us on it. Also please let us know is there any other option for accomplish this scenario. Thanks Geo

• Is there an antipattern to describe this method of coding?

  - by P.Brian.Mackey

  I have a codebase where the programmer tended to wrap things up in areas that don't make sense. For example, given an Error log we have you can log via ErrorLog.Log(ex, "friendly message"); He added various other means to accomplish the exact same task. E.G. SomeClass.Log(ex, "friendly message"); Which simply turns around and calls the first method. This adds levels of complexity with no added benefit. Is there an anti-pattern to describe this?

• protected abstract override Foo(); &ndash; er... what?

  - by Muljadi Budiman

  A couple of weeks back, a co-worker was pondering a situation he was facing.  He was looking at the following class hierarchy: abstract class OriginalBase { protected virtual void Test() { } } abstract class SecondaryBase : OriginalBase { } class FirstConcrete : SecondaryBase { } class SecondConcrete : SecondaryBase { } Basically, the first 2 classes are abstract classes, but the OriginalBase class has Test implemented as a virtual method.  What he needed was to force concrete class implementations to provide a proper body for the Test method, but he can’t do mark the method as abstract since it is already implemented in the OriginalBase class. One way to solve this is to hide the original implementation and then force further derived classes to properly implemented another method that will replace it.  The code will look like the following: abstract class OriginalBase { protected virtual void Test() { } } abstract class SecondaryBase : OriginalBase { protected sealed override void Test() { Test2(); } protected abstract void Test2(); } class FirstConcrete : SecondaryBase { // Have to override Test2 here } class SecondConcrete : SecondaryBase { // Have to override Test2 here } With the above code, SecondaryBase class will seal the Test method so it can no longer be overridden.  Then it also made an abstract method Test2 available, which will force the concrete classes to override and provide the proper implementation.  Calling Test will properly call the proper Test2 implementation in each respective concrete classes. I was wondering if there’s a way to tell the compiler to treat the Test method in SecondaryBase as abstract, and apparently you can, by combining the abstract and override keywords.  The code looks like the following: abstract class OriginalBase { protected virtual void Test() { } } abstract class SecondaryBase : OriginalBase { protected abstract override void Test(); } class FirstConcrete : SecondaryBase { // Have to override Test here } class SecondConcrete : SecondaryBase { // Have to override Test here } The method signature makes it look a bit funky, because most people will treat the override keyword to mean you then need to provide the implementation as well, but the effect is exactly as we desired.  The concepts are still valid: you’re overriding the Test method from its original implementation in the OriginalBase class, but you don’t want to implement it, rather you want to classes that derive from SecondaryBase to provide the proper implementation, so you also make it as an abstract method. I don’t think I’ve ever seen this before in the wild, so it was pretty neat to find that the compiler does support this case.

• Is there an application or method to log of data transfers?

  - by Gaurav_Java

  My friend asked me for some files that I let him take from my system. I did not see he doing that. Then I was left with a doubt: what extra files or data did he take from my system? I was thinking is here any application or method which shows what data is copied to which USB (if name available then shows name or otherwise device id) and what data is being copied to Ubuntu machine . It is some like history of USB and System data. I think this feature exists in KDE This will really useful in may ways. It provides real time and monitoring utility to monitor USB mass storage devices activities on any machine.

• What's New in Oracle VM VirtualBox 4.2?

  - by Fat Bloke

  A year is a long time in the IT industry. Since the last VirtualBox feature release, which was a little over a year ago, we've seen: new releases of cool new operating systems, such as Windows 8, ChromeOS, and Mountain Lion; we've seen a myriad of new Linux releases from big Enterprise class distributions like Oracle 6.3, to accessible desktop distros like Ubuntu 12.04 and Fedora 17; and we've also seen the spec of a typical PC or laptop double in power. All of these events have influenced our new VirtualBox version which we're releasing today. Here's how... Powerful hosts  One of the trends we've seen is that as the average host platform becomes more powerful, our users are consistently running more and more vm's. Some of our users have large libraries of vm's of various vintages, whilst others have groups of vm's that are run together as an assembly of the various tiers in a multi-tiered software solution, for example, a database tier, middleware tier, and front-ends.  So we're pleased to unveil a more powerful VirtualBox Manager to address the needs of these users: VM Groups Groups allow you to organize your VM library in a sensible way, e.g.  by platform type, by project, by version, by whatever. To create groups you can drag one VM onto another or select one or more VM's and choose Machine...Group from the menu bar. You can expand and collapse groups to save screen real estate, and you can Enter and Leave a group (think iPad navigation here) by using the right and left arrow keys when groups are selected. But groups are more than passive folders, because you can now also perform operations on groups, rather than all the individual VMs. So if you have a multi-tiered solution you can start the whole stack up with just one click. Autostart Many VirtualBox users run dedicated services in their VMs, for example, running a Wiki. With these types of VM workloads, you really want the VM start up when the host machine boots up. So with 4.2 we've introduced a cross-platform Auto-start mechanism to allow you to treat VMs as host services. Headless VM Launching With VM's such as web servers, wikis, and other types of server-class workloads, the Console of the VM is pretty much redundant. For some time now VirtualBox has offered a separate launch mechanism for these VM's, namely the command-line interface commands VBoxHeadless or VBoxManage startvm ... --type headless commands. But with 4.2 we also allow you launch headless VMs from the Manager. Simply hold down Shift when launching the VM from the Manager.  It's that easy. But how do you stop a headless VM? Well, with 4.2 we allow you to Close the VM from the Manager. (BTW best to use the ACPI Shutdown method which allows the guest VM to close down gracefully.) Easy VM Creation For our expert users, the  New VM Wizard was a little tiresome, so now there's a faster 2-click VM creation mode. Just Hide the description when creating a new VM. Powerful VMs  As the hosts have become more powerful, so are the guests that are running inside them. Here are some of the 4.2 features to accommodate them: Virtual Network Interface Cards  With 4.2, it's now possible to create VMs with up to 36 NICs, when using the ICH9 chipset emulation. But with great power comes great responsibility (didn't Obi-Wan say something similar?), and so we have also introduced bandwidth limiting to prevent a rogue VM stealing the whole pipe. VLAN tagging Some of our users leverage VLANs extensively so we've enhanced the E1000 NICs to support this.  Processor Performance If you are running a CPU which supports Nested Paging (aka EPT in the Intel world) such as most of the Core i5 and i7 CPUs, or are running an AMD Bulldozer or later, you should see some performance improvements from our work with these processors. And while we're talking Processors, we've added support for some of the more modern VIA CPUs too. Powerful Automation Because VirtualBox runs atop a fully blown operating system, it makes sense to leverage the capabilities of the host to run scripts that can drive the guest VMs. Guest Automation was introduced in a prior release but with 4.2 we've revamped the APIs to allow a richer and more powerful set of operations to be executed by the guest. Check out the IGuest APIs in the VirtualBox Programming Guide and Reference (SDK). Powerful Platforms  All the hardcore engineering that has gone into 4.2 has been done for a purpose and that is to deliver a fast and powerful engine that can run almost any x86 OS because of the integrity of the virtualization. So we're pleased to add support for these platforms: Mac OS X "Mountain Lion"  Windows 8 Windows Server 2012 Ubuntu 12.04 (“Precise Pangolin”) Fedora 17 Oracle Linux 6.3  Here's the proof: We don't have time to go into the myriad of smaller improvements such as support for burning audio CDs from a guest, bi-directional clipboard control,  drag-and-drop of files into Linux guests, etc. so we'll leave that as an exercise for the user as soon as you've downloaded from the Oracle or community site and taken a peek at the User Guide. So all in all, a pretty solid release, one that we hope you'll enjoy discovering. - FB

• How can you tell whether to use Composite Pattern or a Tree Structure, or a third implementation?

  - by Aske B.

  I have two client types, an "Observer"-type and a "Subject"-type. They're both associated with a hierarchy of groups. The Observer will receive (calendar) data from the groups it is associated with throughout the different hierarchies. This data is calculated by combining data from 'parent' groups of the group trying to collect data (each group can have only one parent). The Subject will be able to create the data (that the Observers will receive) in the groups they're associated with. When data is created in a group, all 'children' of the group will have the data as well, and they will be able to make their own version of a specific area of the data, but still linked to the original data created (in my specific implementation, the original data will contain time-period(s) and headline, while the subgroups specify the rest of the data for the receivers directly linked to their respective groups). However, when the Subject creates data, it has to check if all affected Observers have any data that conflicts with this, which means a huge recursive function, as far as I can understand. So I think this can be summed up to the fact that I need to be able to have a hierarchy that you can go up and down in, and some places be able to treat them as a whole (recursion, basically). Also, I'm not just aiming at a solution that works. I'm hoping to find a solution that is relatively easy to understand (architecture-wise at least) and also flexible enough to be able to easily receive additional functionality in the future. Is there a design pattern, or a good practice to go by, to solve this problem or similar hierarchy problems? EDIT: Here's the design I have: The "Phoenix"-class is named that way because I didn't think of an appropriate name yet. But besides this I need to be able to hide specific activities for specific observers, even though they are attached to them through the groups. A little Off-topic: Personally, I feel that I should be able to chop this problem down to smaller problems, but it escapes me how. I think it's because it involves multiple recursive functionalities that aren't associated with each other and different client types that needs to get information in different ways. I can't really wrap my head around it. If anyone can guide me in a direction of how to become better at encapsulating hierarchy problems, I'd be very glad to receive that as well.

• Reliable method for google analytics tracking for print advertising campaign?

  - by chrisjlee

  A client is looking to track advertising clicks through a newspaper ad to measure success. They have rigid business requirements that it will be a unique domain... e.g. foowidgetsnews.net instead of foodwidgets.com/contact-form-page.php What is the most reliable method of building redirected url to a landing page so it will be tracked in google analytics as a direct hit from the newspaper? Finally, we would like to track the foowidgetsnews.net as the main url in google analytics because 301 redirect isn't tracked in google analytics like the way we would like it to.

• Is the php method md5() secure? Can it be used for passwords? [migrated]

  - by awiebe

  So executing a php script causes the form values to be sent to the server, and then they are processed. If you want to store a password in your db than you want it to be a cryptographic hash(so your client side is secure, can you generate an md5 using php securely( without submitting the user:password pair in the clear), or is there an alternative standard method of doing this, without having the unecrypted pasword leaving the clients machine? Sorry if this is a stupid question I'm kind of new at this. I think this can be done somehow using https, and on that note if a site's login page does not use https, does that mean that while the databse storage is secure, the transportation is not?

• Rails Fixtures Don't Seem to Support Transitive Associations

  - by Rick Wayne

  So I've got 3 models in my app, connected by HABTM relations: class Member < ActiveRecord::Base has_and_belongs_to_many :groups end class Group < ActiveRecord::Base has_and_belongs_to_many :software_instances end class SoftwareInstance < ActiveRecord::Base end And I have the appropriate join tables, and use foxy fixtures to load them: -- members.yml -- rick: name: Rick groups: cals -- groups.yml -- cals: name: CALS software_instances: delphi -- software_instances.yml -- delphi: name: No, this is not a joke, someone in our group is still maintaining Delphi apps... And I do a rake db:fixtures:load, and examine the tables. Yep, the join tables groups_members and groups_software_instances have appropriate IDs in, big numbers generated by hashing the fixture names. Yay! And if I run script/console, I can look at rick's groups and see that cals is in there, or cals's software_instances and delphi shows up. (Likewise delphi knows that it's in the group cals.) Yay! But if I look at rick.groups[0].software_instances...nada. []. And, oddly enough, rick.groups[0].id is something like 30 or 10, not 398398439. I've tried swapping around where the association is defined in the fixtures, e.g. -- members.yml -- rick name: rick -- groups.yml -- cals name: CALS members: rick No error, but same result. (Later: Confirmed, same behavior on MySQL. In fact I get the same thing if I take the foxification out and use ERB to directly create the join tables, so: -- license_groups_software_instances -- cals_delphi: group_id: <%= Fixtures.identify 'cals' % software_instance_id: <%= Fixtures.identify 'delphi' $ Before I chuck it all, reject foxy fixtures and all who sail in her and just hand-code IDs...anybody got a suggestion as to why this is happening? I'm currently working in Rails 2.3.2 with sqlite3, this occurs on both OS X and Ubuntu (and I think with MySQL too). TIA, my compadres.

• VB.NET - Find a Substring in an ArrayList, StringCollection or List(Of String)

  - by CJM

  I've got some code that creates a list of AD groups that the user is a member of, with the intention of saying 'if user is a member of GroupX then allow admin access, if not allow basic access'. I was using a StringCollection to store this list of Groups, and intended to use the Contains method to test for membership of my admin group, but the problem is that this method only compares the full string - but my AD groups values are formatted as cn=GroupX, etc.... I want to be easily able to determine if a particular substring (i.e. 'GroupX') appears in the list of groups. I could always iterate through the groups check each for a substring representing my AD group name, but I'm more interested in finding out if there is a 'better' way. Clearly there are a number of repositories for the list of Groups, and it appears that Generics (List(Of String)) are more commonly preferred (which I may well implement anyway) but there is no in-built means of checking for a substring using this method either. Any suggestions? Or should I just iterated through the list of groups?

• Running single test class or group with Surefire and TestNG

  - by Slartibartfast

  I want to run single test class from command line using Maven and TestNG Things that doesn't work: mvn -Dtest=ClassName test I have defined groups in pom.xml, and this class isn't in one of those groups. So it got excluded on those grounds. mvn -Dgroups=skipped-group test mvn -Dsurefire.groups=skipped-group test when config is <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <version>2.7.1</version> <configuration> <groups>functest</groups> </configuration> </plugin> Parameters work fine in there are no groups defined in pom.xml. Similarly, when surefire is configured with <configuration> <includes> <include>**/*UnitTest.java</include> </includes> </configuration> I can add another test with -Dtest parameter, but cannot add group. In any combination, I can narrow down tests to be executed with groups, but not expand them. What's wrong with my configuration? Is there a way to run a single test or group outside of those defined in pom.xml? Tried on Ubuntu 10.04 with Maven 2.2.1, TestNG 5.14.6 and Surefire 2.7.1

• Is there a name for a testing method where you compare a set of very different designs?

  - by DVK

  "A/B testing" is defined as "a method of marketing testing by which a baseline control sample is compared to a variety of single-variable test samples in order to improve response rates". The point here, of course, is to know which small single-variable changes are more optimal, with the goal of finding the local optimum. However, one can also envision a somewhat related but different scenario for testing the response rate of major re-designs: take a baseline control design, take one or more completely different designs, and run test samples on those redesigns to compare response rates. As a practical but contrived example, imagine testing a set of designs for the same website, one being minimalist "googly" design, one being cluttered "Amazony" design, and one being an artsy "designy" design (e.g. maximum use of design elements unlike Google but minimal simultaneously presented information, like Google but unlike Amazon) Is there an official name for such testing? It's definitely not A/B testing, since the main component of it (finding local optimum by testing single-variable small changes that can be attributed to response shift) is not present. This is more about trying to compare a set of local optimums, and compare to see which one works better as a global optimum. It's not a multivriable, A/B/N or any other such testing since you don't really have specific variables that can be attributed, just different designs.

• Is defining every method/state per object in a series of UML diagrams representative of MDA in general?

  - by Max

  I am currently working on a project where we use a framework that combines code generation and ORM together with UML to develop software. Methods are added to UML classes and are generated into partial classes where "stuff happens". For example, an UML class "Content" could have the method DeleteFromFileSystem(void). Which could be implemented like this: public partial class Content { public void DeleteFromFileSystem() { File.Delete(...); } } All methods are designed like this. Everything happens in these gargantuan logic-bomb domain classes. Is this how MDA or DDD or similar usually is done? For now my impression of MDA/DDD (which this has been called by higherups) is that it severely stunts my productivity (everything must be done The Way) and that it hinders maintenance work since all logic are roped, entrenched, interspersed into the mentioned gargantuan bombs. Please refrain from interpreting this as a rant - I am merely curious if this is typical MDA or some sort of extreme MDA UPDATE Concerning the example above, in my opinion Content shouldn't handle deleting itself as such. What if we change from local storage to Amazon S3, in that case we would have to reimplement this functionality scattered over multiple places instead of one single interface which we can provide a second implementation for.

• How lookaheads are propagated in "channel" method of building LALR parser?

  - by greenoldman

  The method is described in Dragon Book, however I read about it in ""Parsing Techniques" by D.Grune and C.J.H.Jacobs". I start from my understanding of building channels for NFA: channels are built once, they are like water channels with current you "drop" lookahead symbols in right places (sources) of the channel, and they propagate with "current" when symbol propagates, there are no barriers (the only sufficient things for propagation are presence of channel and direction/current); i.e. lookahead cannot just die out of the blue Is that right? If I am correct, then eof lookahead should be present in all states, because the source of it is the start production, and all other production states are reachable from start state. How the DFA is made out of this NFA is not perfectly clear for me -- the authors of the mentioned book write about preserving channels, but I see no purpose, if you propagated lookaheads. If the channels have to be preserved, are they cut off from the source if the DFA state does not include source NFA state? I assume no -- the channels still runs between DFA states, not only within given DFA state. In the effect eof should still be present in all items in all states. But when you take a look at DFA presented in book (pdf is from errata): DFA for LALR (fig. 9.34 in the book, p.301) you will see there are items without eof in lookahead. The grammar for this DFA is: S -> E E -> E - T E -> T T -> ( E ) T -> n So how it was computed, when eof was dropped, and on what condition? Update It is textual pdf, so two interesting states (in DFA; # is eof): State 1: S--- >•E[#] E--- >•E-T[#-] E--- >•T[#-] T--- >•n[#-] T--- >•(E)[#-] State 6: T--- >(•E)[#-)] E--- >•E-T[-)] E--- >•T[-)] T--- >•n[-)] T--- >•(E)[-)] Arc from 1 to 6 is labeled (.

• What is the best approach to solve a factory method problem which has to be an instance?

  - by Iago

  I have to add new funcionality in a web service legacy project and I'm thinking what is the best approach for a concrete situation. The web service is simple: It receives a XML file, unmarshalling, generates response's objects, marshalling and finally it sends the response as a XML file. For every XML files received, the web service always responds with the same XML structure. What I have to do is to generate a different XML file according to the XML received. So I have a controller class which has all marshalling/unmarshalling operations, but this controller class has to be an instance. Depending on XML received I need some marshalling methods or others. Trying to make few changes on legacy source, what is the best approach? My first approach was to do a factory method pattern with the controller class, but this class has to be an instance. I want to keep, as far as it goes, this structure: classController.doMarshalling(); I think this one is a bit smelly: if(XMLReceived.isTypeOne()) classController.doMarshallingOne(); else if(XMLReceived.isTypeTwo()) classController.doMarshallingTwo(); else if(XMLReceived.isTypeThree()) classController.doMarshallingThree(); else if ... I hope my question is well understood

• Should I make a seperate unit test for a method, if it only modifies the parent state?

  - by Dante

  Should classes, that modify the state of the parent class, but not itself, be unit tested separately? And by separately, I mean putting the test in the corresponding unit test class, that tests that specific class. I'm developing a library based on chained methods, that return a new instance of a new type in most cases, where a chained method is called. The returned instances only modify the root parent state, but not itself. Overly simplified example, to get the point across: public class BoxedRabbits { private readonly Box _box; public BoxedRabbits(Box box) { _box = box; } public void SetCount(int count) { _box.Items += count; } } public class Box { public int Items { get; set; } public BoxedRabbits AddRabbits() { return new BoxedRabbits(this); } } var box = new Box(); box.AddRabbits().SetCount(14); Say, if I write a unit test under the Box class unit tests: box.AddRabbits().SetCount(14) I could effectively say, that I've already tested the BoxedRabbits class as well. Is this the wrong way of approaching this, even though it's far simpler to first write a test for the above call, then to first write a unit test for the BoxedRabbits separately?

• If I want to dual-boot Ubuntu with another OS, what partitioning method should I use?

  - by Jay

  I have Ubuntu running as a vm in VirtualBox at the moment, but in the future, if I want to dual-boot it with Windows or another OS installed on my hard-drive, what partitioning method should I use to make room for it? 1)Manually partition my hard drive via disk management in Windows (or the equivalent in another OS), making appropriate room for the main partition upon which Ubuntu will be installed and swap space; 2)Partition via the Ubuntu installer options; 3)Use gparted or another free tool like it. I am uncertain as to why I would want to use one over the other. Lastly, am I correct to think that it would be the acme of foolishness to try to partition drives within a virtual machine (since that partitioning would be inherently limited to the limitations set upon it by the virtualization software, e.g., VirtualBox)? Thanks! P.S. Oh, and I am also planning on not modifying the MBR of Windows if I ever do dual-boot with Ubuntu, using instead a piece of free software (like easyBCD or something) to avoid the headaches of Grub being overwritten by a Windows update.

• Dependency Injection: where to store dependencies used by only one method?

  - by simoneL

  I developing a project integrated with Dependency Injection (just for reference, I'm using Unity). The problem is that I have some Manager classes with several methods and in many cases I have dependencies used only in one method. public class UserManager : IUserManager { private UserRepository UserRepository {get;set;} private TeamRepository TeamRepository {get;set;} private CacheRepository CacheRepository {get;set;} private WorkgroupRepository WorkgroupRepository {get;set;} public UserManager(UserRepository userRepository, TeamRepository teamRepository, CacheRepository cacheRepository , WorkgroupRepository workgroupRepository, ... // Many other dependencies ) { UserRepository = userRepository; TeamRepository = teamRepository; CacheRepository = cacheRepository ; WorkgroupRepository = workgroupRepository; ... // Setting the remaining dependencies } public void GetLatestUser(){ // Uses only UserRepository } public void GetUsersByTeam(int teamID){ // Uses only TeamRepository } public void GetUserHistory(){ // Uses only CacheRepository } public void GetUsersByWorkgroup(int workgroupID){ // Uses only workgroupRepository } } The UserManager is instantiated in this way: DependencyFactory<IUserManager>(); Note: DependencyFactory is just a wrapper to simplify the access to the UnityContainer Is it OK to have classes like that in the example? Is there a better way to implement avoiding to instantiate all the unnecessary dependencies?

• Is there a way to unit test an async method?

  I am using Xunit and NMock on .NET platform. I am testing a presentation model where a method is asynchronous. The method creates an async task and executes it so the method returns immediately and the state I need to check aren't ready yet. I can set a flag upon finish without modifying the SUT but that would mean I would have to keep checking the flag in a while loop for example, with perhaps timeout. What are my options?

• Spring: Using "Lookup method injection" for my ThreadFactory looks not scalable.

  Hi, We're building a ThreadFactory so everytime a singleton controller needs a new thread, i get a new instance everytime. Looking at Lookup method injection looks good but what if we have multiple threads. like: public abstract class ThreadManager { public abstract Thread createThreadDoA(); public abstract Thread createThreadDoB(); } and config: <bean id="threadManager" class="bla.ThreadManager" singleton="true"> <lookup-method name="createThreadA" bean="threadA" /> <lookup-method name="createThreadB" bean="threadB"/> </bean> <bean id="threadA" class="bla.ThreadA"> <bean id="threadB" class="bla.ThreadB"> and usage: threadManager.createThreadA(); I don't want to create an abstract "create" method for every new threadclass. Is it possible to make this generich like: threadManager.createThread(ThreadA.class); Thank you
