Servlet does has only SingleInstance in web application?

It is a unique instanse of servlet in a web application. Is this true?

If Yes
We mentioned, wherever he or she is supported by the server container/web app automatically?
What happens once the application ends, he moves pool for life?

Why?

Just my thought
As a servlet can handle ziillion requests at the same time, it would be more effective to hava a 'pool' of instances instead of one

Set to false.

Calling a method a thousand times at the same time on the same object is not more expensive that it call simultaneously on a thousand different objects. In fact, it will be a little faster, because you will not have to run the code to decide which object to use, and you will have a perfect locality of reference. The only time you would take a performance hit in one over the other is if this Servlet object has member variables and you can use the synchronization or volatile to keep consistent. However, it is a bad habit to write a servlet with Member variables that is precisely why, and no well written servlet has them.

A container is free to create as much or little of the Servlet as it wants, but the most likely implementation would be to create a single instance, since there is no benefit to the creation of multiple.

  • Customers Web App does not not inside another Web application?

    I have a web application, in this web app detail page, I have a form. I want to take the URL of another article of web app (completely different web application), we introduced the user connected, and insert it into the form.

    I tried to use the following code:

    {module_webappscustomer id = "34977" filter = 'all' resultsPerPage = "1" hideEmptyMessage = "true" sortType = "date" collection = "Summary" template =""}

    {% for r % resume.items}

    View my RESUME online at: example.com {{r.url}}

    {% endfor}

    When the page loads, it inserts the URL of the current detail page, I'm.

    For example:

    It must be returned: example.com/job-seeker/my-resume

    but he makes: example.com/job-posting/job-post-title

    Is this a bug or is at - there a way around this problem?

    I found a work around taking my code {module_webappscustomer... and put it inside an inclusion.} Insert the include instead of the code and it works fine.

  • ClassNotFound on Jdev11g for ADF web application

    I recently installed version jdev11g release on my environment. My ADF web application is deployed on weblogic server (by default). When I try to access a page, I keep getting ClassNotFoundException

    Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Logger
    in java.net.URLClassLoader$ 1.run(URLClassLoader.java:200)
    at java.security.AccessController.doPrivileged (Native Method)
    at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:306)

    I had checked double I have log4j - 1.2.14.jar in my class path. This app worked fine when I had the technology review version of Jdev11 using OC4J instead of Weblogic.

    I also create a simple java application that uses same as pots used on my ADF web application and I only see ClassNotFoundException. The two application has the same external jars in the classpath.

    I'm not sure on exactly what is happening here, it would be great if someone can help and give me a few pointer on this

    Thank you
    Tony

    Did you read this part:

    There is a second possible problem that is specific to the commons-logging and related libraries when it is used with integrated WLS and out-of-the-box configuration (including ADF). Because commons - logging.jar is apparently in the system classpath, attributable to the delegation of the ClassLoader Java works, all log4j at the level of the web application are not visible to the factory default journal. As long as this is the case, you may need to add the following to your web application WEB - INF / weblogic.xml:


    true

    What it does is tell the servlet JSP WLS to let the web application classes to ignore the classes in the system class loader. Standard Java class loader delegation gives priority to system classes.

  • LabView 2013 or 2014 Web Application Server does not start.

    I have a request that I built in 2013 of LabView that uses the Web application server OR. The application worked until end November 2014 when the Web in LabView 2013 application server has stopped working. Specifically, 2 and 1) NI NI Application Server Web services) Web Server system both were running, but I was unable to access web pages that I created earlier, or I could access the Configuration Web page OR localhost:3582. In addition, the button "Configure Web Application Server" under "Options/Web Server" is gray. Makes me think that web services NOR did not start successfully upward. Complete a repair facility OR to the LabView 2013 install did not help either.

    Since the opening of a service ticket with NEITHER, I've now deleted and reinstalled the 2013 LabView and LabView 2014 each with the latest patches. But the problem persists.

    The ticket OR for that matter now rests with RnD, so I'm tender hand to the community OR to see if anyone sees something similar? Or has any ideas to try?

    Some additional notes:

    (1) contrary to LabView LabView 2013 2014 no web services NOR would begin, based on a new for 2014 dependence on the Authentication Service of NOR. In 2014 this service does not either.

    (2) when I uninstall 2014 and re-install 2013, chess happens again (as above).

    (3) my system runs Win 7 Pro x 64 with 8 GB of RAM.

    (4) I have McAfee virus scanner/firewall. I have disabled and even uninstalled without correcting the problems.

    At this point any ideas to try would be greatly appreciated, because I can't wipe my OS and start over.

    Thank you

    * Update *.

    I finally found a solution to this problem. The solution is the following:

    1. Delete the two files "C:\ProgramData\National Instruments\NIAuth"

      • commitmark.1
      • Registry.bin
    2. Restart the OS and re-launching of LabView.

    On the next reboot, LabView recreates these two files and the Web services OR Windows services start normally. Once NI WebService which works normally.

    I'm assuming that one or both of these files has become corrupted at some point, that has kept the WebServices OR start properly. But as none of the services OR created an error event Windows for that matter, I stayed to search for the solution. And since the installer NOR has not remove or repair any of these files, the question continues to no matter how many times I have re-installed LabView on my system.

  • Detect when a person has presented a Web application using liquid?

    I have a web application that allows anyone to edit the items in a web application, however, I want only certain users to be able to edit this web application. I have some safe zones assigned to these users. I use module_data, so I don't know what secure areas, the user is subscribed to. I can then run the following logic:

    {% If RescueVolunteer is 'True' or Director is 'True' or Admin == 'True'-%}

    <!-FORM of CHANGE see - >

    {%-%}

    You do not have permissions to view this page. If there is an error, please contact us.

    {endif %}

    This works great but I ran into an issue. With this web application in particular, for each element, we add the field "presented by" so that the user will be able to modify this point. This particular user can change the web application element they are assigned to and are not attributed to one of the areas of security that has editing access.

    Is there a way to detect, using liquid, when a user is assigned to the subject field? In other words, I want to be able to do this:

    {% If file is 'True'-%}

    DISPLAY THE FORM

    {endif %}

    I checked the {{this | json}} but don't see anything that I could use. Is there something?

    I thought about adding the {module_webappcustomer} on the page to execute the logic, but I did not understand what a moment.

    No indication on how this can be achieved would be very appreciated!

    Hi Lynda,

    A solution we came up with many years ago, almost liquid, but still topical today, was to add in another field in the site web app called ' presented by ', and it simply reproduces the generation presented by feature. Place the email address of the owner of items in the web app in this new custom field to manually check if current logged-in user has access to change this point of current web application.

    It's barbaric, I know, but it works.

  • Can deploy us the fusion ADF in logical server web application war file? EAR works only

    I created a fusion ADF application in Jdeveloper.

    When I deploy it as a WAR in integrated weblogic server file. -works fine.

    When I deployed in the file. WAR in stand-alone weblogic server. -.

    It gives me error 500.

    In the console (startweblogic.cmd) ""java.lang.NoClassDefFoundError: oracle, adf, model, RegionBinding "."

    Then I found on the internet that deploying any application like EAR would solve. Yes. He has indeed solved. My application works well in stand-alone weblogic.

    Now my question is "can deploy us not like war in stand-alone weblogic?

    The war file works quite well under the integrated form but not in stand-alone. Why?

    PS: I have installed the runtime of the ADF, established the deployment profile to deploy a web application.

    Thanks in advance.

    Dear user,

    ADF applications can only be deployed as an EAR file (actually it's what JDeveloper when you run an application.) It creates an EAR on the fly and deploy it on the built-in WLS).

    Please see Deploying a Java EE Application ADF - 11 g Release 1 (11.1.1.6.0) for more info.

    In the future, can you please provide us with some basic information such as your version of JDeveloper.

  • Problems to open the Web Application host with only IE comments

    I'm running a Windows 2008 R2 using VMWare Workstation 7.1.5 prompt.  The customer has an installed web application which is only compatible with MS Internet Explorer.  The guest network is configured to use NAT.

    When my host is connected to the local network of my company, I can use Internet Explorer to host to access web applications of the customer without any problem.

    When my host is not connected to the local network of my company (completely disconnected, or connected to a different network) I can't use Internet Explorer of the host to access web application of the burst.  But I can use the host Chrome or Firefox to access the customer applications.

    My company has my locked host IE while I can't make changes to it.  Is there something I can do with my network settings to get IE think it is connected to the local network of the company?

    Thanks Steve

    It wasn't a DNS issue since I knew that I was able to connect using Chrome.

    It was a restriction of IE, but I was finally able to work around this problem.  My company gave me access to a local account on the machine that had full administrative rights.  Since it is a local account is not all corporate policies pushed to him.  In case you're wondering, I created a shortcut with the following command:

    C:\Windows\System32\runas.exe/user:\administrator "C:\Program Files (x 86) \Internet.

    Runs like a champ.  You will be asked for the password for the local account and then you are able to IE without restrictions.

    I wish that we thought of this earlier

    It was a problem introduced with the new deployment of LabVIEW web services in 2013, specifically on laptops (classified as CAR 422680). It is fixed in the patch of f1 2013 LabVIEW. This patch is available for download here and you can get more information about the patches in the patch here. The patch will travel via Service Update OR later this month.

  • How to add jsession ID to an ADF web application deployed in weblogic server?

    Hello

    I use jdeveloper 11.1.2.4 version. Can anyone tell please how to add custom JSESSIONID (BLTSESSIONID) to the URL of the web application ADF that must be deployed in weblogic server. I tried the following approach. but it did not work for me.

    in webogic.xml, I added

    < session descriptor - >

    < name > BLTSESSIONID < / cookie-name >

    < / session descriptor >

    However, I've added the weblogic.xml manually from the gallery.

    Could someone help me on this please?

    Thank you

    You don't have to add the session ID to the URL. The Web application automatically manages session IDS. By default, it uses an HTTP cookie (a cookie with name JSESSIONID) therefor. The Web application will automatically add it to the URL only if it detects that the client browser does not support cookies (for example, if the user has disabled cookies in the browser). By adding the lines above to weblogic.xml you just changed the name of cookie JSESSIONID to BLTSESSIONID default session. This is useful only if you have access to a couple of different Web applications from one and the same server and you want every application to maintain a clean session (for example, each application having a different session cookie name). If all applications on the server use one and same name cookie (JSESSIONID for example) and you have access to more than one application at the same time in one and the same browser (and even multiple instances of the browser, with the exception of some special cases), you will not be able to work with these applications correctly because the next access to another application will replace the cookie and you will lose the session to the requests earlier. Because HTTP cookies are maintained at the level of server name, it's not at the level of application root. In this case, you must specify the application names specific cookie (what you did above).

    http://www.BlackBerry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800708/800655/How_To _...

    And I read about 'push channel browser', which seems to do exactly what I want to do:

    http://www.BlackBerry.com/knowledgecenterpublic/livelink.exe/fetch/2000/7979/1181821/832210/Developi...

    I did a test with my Blackberry that is connected to a BES, and it works very well using the code example.

    My question is this, 'channel browser push' can be used for Blackberry that is not configured in our BES.

    For example, I want to be able to deploy an icon on the Blackberry from customers and suppliers we have, but these Blackberries are not related at all our BES or network.

    Is it possible to do this?  If so, should I do something special to make it work?

    If not, does that mean my only solution is to create a Java application that automatically launch the browser Blackberry (second option from the first link)?

    Thanks for your help!

    Channel browser push you make reference to requires the user is on a BlackBerry Enterprise Server.

    The alternatives to this is a Java application (as you have discovered), BlackBerry Widget or Signal of Web.  Web signals is the equivalent to a BlackBerry Internet Server Browser channel thrust.

  • BlackBerry Smartphones test web application through BlackBerry Simulator.

    Hello

    I have to test my web application on a blackberry Simulator. My first question is: if it is possible to test any web application using the Simulator or I can test only the rich applcations of BlackBerry?

    I do the following:

    1. I downloaded Black Berry Email and MDS services Simulator 4.1.2 and BlackBerry_Simulators_4.7.0.78_9500 - Vodafone.exe.

    2A started the MDS Simulator first, then the BB Simulator.

    But I am not able to connect to internet, BB Simulator. Am I missing a config in the MDS Simulator.

    Help, please. This is urgent. TIA.

    Hello

    Open the rimpublic.property file. The rimpublic.property file is located in the following locations: \Program Files\Research In Motion\BlackBerry Email and Simulators\MDS\config of MDS

    Then add these commands in the section [MANAGER HTTP], update the following:

    application.handler.http.proxyEnabled = true

    application.handler.http.proxyHost = hostname

    application.handler.http.proxyPort = hostport
    application.handler.http.proxyUser = username

    application.handler.http.proxyPass = password

    application.handler.http.proxyAutoConfig = true

    application.handler.http.proxyAutoConfigURL = http://URL_to_Your_Config_File

    application.handler.http.proxyAutoConfig.ScriptCacheTime = 0

    Save these changes and to make with your steps... that will succeed to open a web application on your Simulator... more can know which web application (i.e. URL) that you want to test... I had the same problem, but somehow managed to open sites to Simulator after adding these commands. But my main concern is to open a URL in sector public siebel that is installed on a server in 9530 Simulator device. Can you/only you know which deals with the implementation of CRM siebel on simulators could you please suggest me doing this task.

    Thanks in advance
