  • How to find dynamically loaded modules (the static ones) programatically in windows

    - by Ryan Rohrer
    I'm trying to port the unix utility ldd to windows, because dependency walker and cygcheck don't quite give me the usage I'm looking for. (also for the learning experience) Ive been looking all over MSDN, for a windows API that lists dll dependencies of an executable, or even the storage format in the complied exe (just to filter it out), but I've been unable to find anything. If anyone knows what API call windows uses for listing modules to load, or what patterns I can search for in an executable to find modules to load, please help me out :) thanks! -note: I'm not looking to profile for dynamic modules, just list the ones that are required at runtime

  • Sharing memory between modules

    - by John Holecek
    Hi, I was wondering how to share some memory between different program modules - lets say, I have a main application (exe), and then some module (dll). They both link to the same static library. This static library will have some manager, that provides various services. What I would like to achieve, is to have this manager shared between all application modules, and to do this transparently during the library initialization. Between processes I could use shared memory, but I want this to be shared in the current process only. Could you think of some cross-platform way to do this? Possibly using boost libraries, if they provide some facilities to do this. Only solution I can think of right now, is to use shared library of the respective OS, that all other modules will link to at runtime, and have the manager saved there.

  • Why can I run JUnit tests for my Spring project, but not a main method?

    - by FarmBoy
    I am using JDBC to connect to MySQL for a small application. In order to test without altering the real database, I'm using HSQL in memory for JUnit tests. I'm using Spring for DI and DAOs. Here is how I'm configuring my HSQL DataSource <bean id="mockDataSource" class="org.springframework.jdbc.datasource.SingleConnectionDataSource"> <property name="driverClassName" value="org.hsqldb.jdbcDriver"/> <property name="url" value="jdbc:hsqldb:mem:mockSeo"/> <property name="username" value="sa"/> </bean> This works fine for my JUnit tests which use the mock DB. But when I try to run a main method, I find the following error: Error creating bean with name 'mockDataSource' defined in class path resource [beans.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are: PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'driverClassName' threw exception; nested exception is java.lang.IllegalStateException: Could not load JDBC driver class [org.hsqldb.jdbcDriver] I'm running from Eclipse, and I'm using the Maven plugin. Is there a reason why this would work as a Test, but not as a main()? I know that the main method itself is not the problem, because it works if I remove all references to the HSQL DataSource from my Spring Configuration file.

  • How do I specify Open ID Realm in spring security ?

    - by Salvin Francis
    We are using Spring security in our application with support for username / password based authentication as well as Open id based authentication. The issue is that google gives a different open id for the return url specified and we have at least 2 different entry points in our application from where open id is configured into our system. Hence we decided to use open id realm. http://blog.stackoverflow.com/2009/0...ue-per-domain/ http://groups.google.com/group/googl...unts-api?pli=1 how is it possible to integrate realm into our spring configuration/code ? This is how we are doing it in traditional openid library code: AuthRequest authReq = consumerManager.authenticate(discovered, someReturnToUrl,"http://www.example.com"); This works and gives same open id for different urls from our site. our configuration: Code: ... <http auto-config="false"> <!-- <intercept-url> tags are here --> <remember-me user-service-ref="someRememberedService" key="some key" /> <form-login login-page="/Login.html" authentication-failure-url="/Login.html?error=true" always-use-default-target="false" default-target-url="/MainPage.html"/> <openid-login authentication-failure-url="/Login.html?error=true" always-use-default-target="true" default-target-url="/MainPage.html" user-service-ref="someOpenIdUserService"/> </http> ... <beans:bean id="someOpenIdUserService" class="com.something.MyOpenIDUserDetailsService"> </beans:bean> <beans:bean id="openIdAuthenticationProvider" class="com.something.MyOpenIDAuthenticationProvider"> <custom-authentication-provider /> <beans:property name="userDetailsService" ref="someOpenIdUserService"/> </beans:bean> ...

  • How do I implement a listener pattern over RMI using Spring?

    - by predhme
    So here is a generalized version of our application desgin: @Controller public class MyController { @Autowired private MyServiceInterface myServiceInterface; @RequestMapping("/myURL") public @ResponseBody String doSomething() { MyListenerInterface listener = new MyListenerInterfaceImpl(); myServiceInterface.doThenCallListener(listener); // do post stuff } } public interface MyListenerInterface { public void callA(); public void callB(); } public class MyListenerInterfaceImpl implements MyListenerInterface { // ... omitted for clarity } public interface MyServiceInterface { public void doThenCallListener(MyListenerInterface listener); } public class MyServiceImpl { public void doThenCallListener(MyListenerInterface listener) { // do stuff listener.callA(); } } Basically I have a controller that is being called via AJAX in which I am looking to return a response as a string. However, I need to make a call to the backend (MyServiceInterface). That guy is exposed through RMI by using Spring (man that was easy). But the service method as described requires a listener to be registered for invokation completion purposes. So what I assume I need to achieve is transparently to the backend make it so that when the listener methods are called, really the call is going over RMI. I would have thought Spring would have a simple way to wrap a POJO (not a service singleton) with RMI calls. I looked through their documentation but they had nothing besides exposing services via RMI. Could someone point me in the right direction?

    - by vipin
    hi friend, I have created the application in which I need to configure the connection pool.In which I am configuring the connection pooling in the spring_Config file. using the Basicdatasource. but there is some problem to create the connection pool. Please tell me how to create the connection pooling in spring application using BasicDatasource. I tried this one code in spring config ;- bean id="datasource" class="org.apache.commons.dbcp.BasicDataSource" com.mysql.jdbc.Driver jdbc:mysql://192.168.1.12:3306/revup?noAccessToProcedureBodies=true jdbc:mysql://localhost:3306/revup?noAccessToProcedureBodies=true-- revuser root-- kjacob gme997FK-- <property name="poolPreparedStatements"> <value>true</value> </property> <property name="initialSize"> <value>2</value> </property> <property name="maxActive"> <value>15</value> </property> Is there any modification of code please tell me. thanks in advance.

  • How can I use a custom configured RememberMeAuthenticationFilter in spring security?

    - by Sebastian
    I want to use a slightly customized rememberme functionality with spring security (3.1.0). I declare the rememberme tag like this: <security:remember-me key="JNJRMBM" user-service-ref="gymUserDetailService" /> As I have my own rememberme service I need to inject that into the RememberMeAuthenticationFilter which I define like this: <bean id="rememberMeFilter" class="org.springframework.security.web.authentication.rememberme.RememberMeAuthenticationFilter"> <property name="rememberMeServices" ref="gymRememberMeService"/> <property name="authenticationManager" ref="authenticationManager" /> </bean> I have spring security integrated in a standard way in my web.xml: <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> Everything works fine, except that the RememberMeAuthenticationFilter uses the standard RememberMeService, so I think that my defined RememberMeAuthenticationFilter is not being used. How can I make sure that my definition of the filter is being used? Do I need to create a custom filterchain? And if so, how can I see my current "implicit" filterchain and make sure I use the same one except my RememberMeAuthenticationFilter instead of the default one? Thanks for any advice and/or pointers!

  • How to get the set of beans that are to be created in Spring?

    - by cyborg
    So here's the scenario: I have a Spring XML configuration with some lazy-beans, some not lazy-beans and some beans that depend on other beans. Eventually Spring will resolve all this so that only the beans that are meant to be created are created. The question: how can I programmatically tell what this set is? When I use context.getBean(name) that initializes the bean. BeanDefinition.isLazyInit() will only tell me how I defined the bean. Any other ideas? ETA: In DefaultListableBeanFactory: public void preInstantiateSingletons() throws BeansException { if (this.logger.isInfoEnabled()) { this.logger.info("Pre-instantiating singletons in " + this); } synchronized (this.beanDefinitionMap) { for (Iterator it = this.beanDefinitionNames.iterator(); it.hasNext();) { String beanName = (String) it.next(); RootBeanDefinition bd = getMergedLocalBeanDefinition(beanName); if (!bd.isAbstract() && bd.isSingleton() && !bd.isLazyInit()) { if (isFactoryBean(beanName)) { FactoryBean factory = (FactoryBean) getBean(FACTORY_BEAN_PREFIX + beanName); if (factory instanceof SmartFactoryBean && ((SmartFactoryBean) factory).isEagerInit()) { getBean(beanName); } } else { getBean(beanName); } } } } } The set of instantiable beans is initialized. When initializing this set any beans not in this set referenced by this set will also be created. From looking through the source it does not look like there's going to be any easy way to answer my question.

  • Can I add a spring mvc filter using jetty with a jar file?

    - by Juan Manuel
    I have a simple web application disguised as a java application (as in, it's a .jar instead of a .war), and I'd like to use a filter for my requests. If it was a .war, I could initialize it with a WebAppContext and specify a web.xml file where I'd have my filter declaration like this <filter> <filter-name>myFilter</filter-name> <filter-class>MyFilterClass</filter-class> </filter> <filter-mapping> <filter-name>myFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> However, I'm using a simple Context to initialize my application with Spring. Server server = new Server(8082); Context root = new Context(server, "/", Context.SESSIONS); DispatcherServlet dispatcherServlet = new DispatcherServlet(); dispatcherServlet.setContextConfigLocation("classpath:application-context.xml"); root.addServlet(new ServletHolder(dispatcherServlet), "/*"); server.start(); Is there a way to programmatically specify filters for the spring servlet, without using a web.xml file?

  • Excel error "This workbook contains Excel 4.0 macros or Excel 5.0 modules"

    - by James
    I have a workbook that was protected via the Protect Workbook feature. It was sent to someone else to modify. When they sent it back, it was unprotected and when I try to reprotect it I get this error, "This workbook contains Excel 4.0 macros or Excel 5.0 modules. If you would like to password protect or restrict permission to this document, you need to remove these macros." I looked and there are no new macros in the edited file. The original file contained the same macros and it was able to be write protected, so I'm not sure why the modified file is having a problem. What are common causes and solutions for this error and does it make sense for the modified file to have the error when the original doesn't?

  • View httpd/lighttpd modules that are installed on shared hosting

    - by sdek
    I don't have access to the httpd.conf file on this shared host, but I wanted to see which modules are enabled/installed. Is there a (easy) way to find out without access to the httpd.conf file? For example, with PHP you can run a file that has phpinfo() in it to get the PHP info. Anything similar? The web server is lighttpd, which I understand is mostly compatible with apache httpd. (And yes, I am going to email the hosting support, but it sure would be nice to know for the future)

  • Disable Memory Modules In BIOS for Testing Purposes (Optimize Nehalem/Gulftown Memory Performance)

    - by Bob
    I recently acquired an HP Z800 with two Intel Xeon X5650 (Gulftown) 6 core processors. The person that configured the system chose 16GB (8 x 2GB DDR3-1333). I'm assuming this person was unaware these processors have 3 memory channels and to optimize memory performance one should choose memory in multiples of three. Based on this information, I have a question: By entering the BIOS, can I disable the bank on each processor that has the single memory module? If so, will this have any adverse effects or behave differently than physically removing the modules? I ask due to the fact that I prefer to store the extra memory in the system if it truly behaves as if the memory is not even there. Also, I see this as an opportunity to test 12GB vs. 16GB to see if there is a noticeable difference. Note: According to http://www.delltechcenter.com/page/04-08-2009+-+Nehalem+and+Memory+Configurations?t=anon, the current configuration reduces the overall data transfer speed to 1066 and in addition, the memory bandwidth goes down by about 23%.

  • Attachment handling for web application with Jackrabbit

    - by Andrea Girardi
    I need to manage attachments on my Spring web application and I thought to use an open source repository. My app it's a job approval system using J2EE / SPRING 3 Framework and Postgress DB to allow user to tracks the job,right through every step of the approval process. It is a fully managed, collaborative system that operates from a central server and is accessed by a standard internet browser. An user should be able to add an attach to a request or an approval step, so, I though to use Jackrabbit with Postgres database persistence manager. I took a look to this post: http://onjava.com/pub/a/onjava/2006/10/04/what-is-java-content-repository.html?page=1 It's really interesting but, I've some question about this kind of solution :- I seen that Jackrabbit standalone as a Derby database embedded solution for persistence, is it enough for a professional use of the repository with more than 50 request / days (with attachment) ? Is there a reason for which I should use another database manager for persistence instead of the default one ?

  • How to survive if you can only do things your way as a programmer?

    - by niceguyjava
    I hate hibernate, I hate spring and I am the kind of programmer who likes to do things his way. I hate micro-management and other people making decisions for me about what framework I should use, what patterns I should apply (hate patterns too) and what architecture I should design. I consider myself a successful programmer and have a descent financial situation due to my performance in past jobs, but I just can't take the standard Java jobs out there. I really love to design things from scratch and hate when I have to maintain other people's bad code, design and architecture, which is the majority you find out there for sure. Does anybody relate to that? What do you guys recommend me? Open up my on company, do consulting, or just keep looking hard until I find a job that suits my preferences, as hard as this may look like with all the hibernate and spring crap out there?

  • Emacs can't find my installed modules

Obviously, this array @INC doesn't hold the path to my modules, the question is, how can I do that? I didn't find anything on emacs manual. I also googled it but to no avail.

    As a conference speaker, I always look forward to hearing from attendees whether they felt my sessions were valuable and worth their time.  Its always gratifying  get a high score, but of course its the (preferably constructive) criticism thats key to continued improvement.  Im by no means the best technical presenter around, and Im always looking for ways to improve. Ive recently spoken at a few events, including TechEd and an Ohio event called Stir Trek.  DevConnections was actually back in April, but theyre just getting their final evals out to speakers.  TechEd, of course, does online evals so immediately after your talks you can see what people think.  Ill try and post my TechEd evals in the next week or so. I gave 3 talks at DevConnections Spring 2010 / VS2010 Launch which I discussed in this previous blog post.  In this follow-up, Im just going to share some eval info and my thoughts on it, albeit a couple of months later. Pragmatic ASP.NET Tips, Tricks, and Tools Evals Turned In: 27 Overall Eval: 3.74 Average Score: 3.47 89% found the technical level Just Right.  7.4% thought it was too basic (3.6% did not respond).  Since nobody thought the content was Too complex, I could perhaps have added some more complex material, but having about 90% say its Just Right is pretty good. 92% said at least 50% of the material was new to them.  36% said 75% or more was new.  Thats also pretty good, I think. 77.8% can use the information immediately; 15% can use it within 2-6 months (7.2 % no response). Overall 78% rated the session Excellent, 18% Good, 4% Fair. All comments (9): Steve did a great job Excellent session! It was good. Im now super excited to attend Steves other sessions later today.  Very useful. One of the best speakers here.  Bring him back to future conferences please. Continue to have this session with new and old stuff.  I always find something I did not know about. Excellent!  This was the best session Ive seen all week. Did not increase font on all pages could not see. For Steve to have had more sessions. Note to self make the fonts bigger across the board.  Otherwise, this is all good for my ego. :)  This is always a very popular session and one I really enjoy giving.  Tips and Tricks talks are pretty easy because you dont have to go in depth with any particular thing, and theyre almost always with existing technology so youre not dealing with betas, lack of documentation, and other issues.  Its an easy session to do well, in my experience, and one which I think attendees definitely appreciate.   Whats New in ASP.NET MVC 2 Evals Turned In: 23 Overall Eval: 3.77 Average Score: 3.47 (wow, I cant believe I scored better on this talk than the tips and tricks talk, which Ive given many times and was more excited about) 96% found the technical level Just Right.  90% found 50% or more of the material to be new.  43% can use the info immediately, and another 43% can use it within 2-6 months I guess that speaks to adoption rates of MVC 2 among my attendees Overall 74% said the session was Excellent, 22% Good.  4% No Response. All Comments (6): Great job, thank you. Great speaker! Really good, a little lost in the code at some points, but great information. Speaker needs to repeat questions from audience for everyone to hear. Exceeded my expectations. Great speaker, very informative. I really do try to religiously repeat questions from the audience for everyone to hear, but obviously I didnt do it 100% of the time.  Note to self remember to repeat questions.  That and making fonts big are really basic speaker best practices, which just goes to prove that fundamentals are always something that can be perfected.   SOLIDify Your ASP.NET MVC 2 Application Evals Turned In: 8 (!) Overall Eval: 3.63 Average Score: 3.47 As I recall this was one of the last talks of the day / show, which might account for the low number of evals turned in.  I dont recall speaking to an empty room for this talk, although it certainly wasnt as crowded as the tips and tricks talk. 100% found the technical level Just Right.  100% found at least half the material new.  62.5% can use it at once and 37.5% within 2-6 months.  62.5% rated the session Excellent overall; 37.5% Good.  Im thinking there were 5 evals with all 4s checked and 3 with all 3s checked (4 = Excellent, 3 = Good) All Comments (3): This covered many topics Ive read about recently, and it helped reinforce them. It was a nice overview of the solid principle, but I thought there might be specifics for MVC2.  I am glad there is not. Move a little slower. Ok, so another fundamental dont go too fast.  Looks like I got one fundamental tip from the comments of each talk. My Take-Aways Remember the fundamentals.  Its worth going through a checklist prior to presenting to make sure these things are fresh in your mind.  Increase all font sizes.  Repeat all questions from audience members without microphones (this is also a great way to stall for time, btw).  Resist the urge to move too quickly especially if youre nervous or short of time.  Writing this up in a blog post also further reinforces these fundamentals for me, which is one of the main reasons why I do it I retain things better when I write them, and even moreso when I write them for public consumption since I have to really think about what Im saying.  And maybe a few of you find this interesting or helpful, which is a bonus. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • PPP kernel module fails to load

    - by Harel
    I am trying to deal with a problem on a server I don't normally deal with. Out of the blue a script using ppp started failing saying that the ppp kernel module is not loaded. When I try to modprobe it it complains about files missing. Note below that the kernel version the server thinks it at, does not match the kernel version directory in /lib/modules. I'm not sure how this could have happened. Could the other maintainers of the server botched a kernel upgrade? My question is how can I fix this discrepancy. Can I simply rename the lib directory and hope for the best? I don't want to break stuff for the people who actually maintain the server but I do need to fix the PPP issue. $ sudo /sbin/modprobe -v ppp FATAL: Could not load /lib/modules/2.6.35.4-rscloud/modules.dep: No such file or directory $ cat /proc/version Linux version 2.6.35.4-rscloud ([email protected]) (gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5) ) #8 SMP Mon Sep 20 15:54:33 UTC 2010 $ ls /lib/modules/ 2.6.33.5-rscloud

  • Perl EPIC Not recognising installed CPAN modules

    - by Recc
    Eclipse on a mac, was working fine adding new modules until I Installed Text::CSV_XS which Eclips doesn't recognise as added to @INC For instance use strict; use SOAP::Transport::HTTP; SOAP::Transport::HTTP::CGI->dispatch_to('C2FService')->handle; BEGIN { package C2FService; use vars qw(@ISA); @ISA = qw(Exporter SOAP::Server::Parameters); use SOAP::Lite; sub c2f { my $self = shift; my $envelope = pop; my $temp = $envelope->dataof("//c2f/temperature"); return SOAP::Data->name( 'convertedTemp' => ( ( ( 9 / 5 ) * ( $temp->value ) ) + 32 ) ); } } use SOAP::Transport::HTTP; is marked as error if I comment it out use SOAP::Lite; is in turn marked as an error, not found etc the usual if a module is not installed. Both are installed with CPAN and $ perl -c soap-test.pl post-code-check.pl syntax OK Perl is fine CPAN tests are all pass, the code works, only EPIC lags behind. $ pwd && ls /opt/local/lib/perl5/site_perl/5.12.4/SOAP Client.pod Lite Server.pod Constants.pm Lite.pm Test.pm Data.pod Packager.pm Trace.pod Deserializer.pod SOM.pod Transport Fault.pod Schema.pod Transport.pod Header.pod Serializer.pod Utils.pod And if I have use errors in the start of my files the rest of the source is not error checked..

  • Errors to do with modules when using net-snmp utils

    - by bob
    I was using the net-snmp packages that come with my linux distro (version 5.3.2.2), but wanted to do some work with the latest version of net-snmp (5.7), so tried compiling and installing the new source. It seemed to work ok but now I'm getting a load of errors when use net-snmp utils (snmpget, snmpset snmpwalk etc..) for example: $ snmptranslate -On SNMPv2-MIB::system.sysDescr MIB search path: /home/me/.snmp/mibs:/usr/local/share/snmp/mibs Cannot find module (SNMPv2-SMI) At line 6 in /usr/local/share/snmp/mibs/SNMPv2-MIB.txt Cannot find module (SNMPv2-TC): At line 9 in /usr/local/share/snmp/mibs/SNMPv2-MIB.txt Cannot find module (SNMPv2-MIB): At line 9 in (none) : <a lot of similar lines> : Cannot find module (NET-SNMP-VACM-MIB): At line 9 in (none) .1.3.6.1.2.1.1.1 From this I assumed perhaps that I was missing mibs from the 'MIB search path', so I looked at the first error 'Cannot find module (SNMPv2-SMI)', however it seems to be in the right directory: $ ls /usr/local/share/snmp/mibs/*SNMPv2-SMI* /usr/local/share/snmp/mibs/SNMPv2-SMI.txt And the same result for the other in the list.. so I'm wondering if anybody knows why it might not be finding the modules even though they seem to be in the search path?

  • Memory modules not running at rated speeds.

    - by Wesley
    Hi all, I'm having some odd memory issues with my build. Here are my specs right now: QDI Superb 4 motherboard Intel Pentium 4 Northwood 2.4GHz (512KB L2, 533MHz FSB) 3x 256MB PC2100 DDR266 RAM 16MB NVIDIA TNT2 Pro AGP Seagate 80GB IDE HDD Generic USB 2.0 PCI Generic Modem PCI Bestec 250W PSU To be even more specific, here are the current brands and models of each module: Kingston KVR266X64C25/256 Samsung PC2100U-25331-Z SMART SM5643285D4N0CHM0H Supposedly, they are all PC2100 266MHz modules with a latency of 2.5. Looking in Speccy, the Kingston module is somehow running at a speed of PC2300 ~284MHz. I've never overclocked RAM at all as I don't know how to. However, when I first started the computer, I had the SMART module in place first and then reset the BIOS settings, including the integrated overclocking options. However, this still doesn't explain why the Kingston module runs at a higher speed than the SMART and Samsung module. Why is it like this? On a side note, where could I find the motherboard manual for the QDI Superb 4? Thanks in advance.
