  • Saving objects in servlet session and java.io.NotSerializableException

    - by EugeneP
    SEVERE: IOException while loading persisted sessions: java.io.WriteAbortedException: writi ng aborted; java.io.NotSerializableException: That means this object cannot be persisted on hard disk. Does it imply that it's not safe to keep in Session objects that do not implement "Serializable"? I haven't heard that there are limitations on saving non-serializable objects in Session object. It simply means that Tomcat will always keep them in memory, right?

  • how to convince website users to use openid

    - by isolatedIterator
    Perhaps this isn't the best forum for this question. If so, would one of the other child sites be more suitable? I am wondering how to overcome the learning curve of convincing a non-technical bunch of users how and what open id is. how do you convince users that it is a good thing and that they want to use it?

  • SQL programming interface to external storage application

    - by Gopala
    My application is a non-relational database application with a tcl interface to retrieve data. I would like to add SQL programming interface to my application. Is there any library that converts SQL/PLSQL statements to API calls? It should also support stored procedures. SQLite(Embedded) has 'virtual table' mechanism that suits my requirement but it lacks stored procedure feature. -Gopala

  • Using pragma once in a C++ project in Xcode 4

    - by Nils
    I know that #pragma once is non-standard, however it is supported by most compilers. So on my Mac I can compile C++ code with headers that use #pragma once on the command line using clang++. The strange thing however is that it does not seem to work within Xcode. I get Invalid preprocessing directive when I try to use #pragma once. I am using the newest version of OSX (10.8.2) and Xcode (Version 4.5.1 (4G1004)).

RSA key fingerprint is a2:c3:fd:d7:f7:75:df:dd:49:64:ce:64:cc:98:e6:2c. Are you sure you want to continue connecting (yes/no)?

  • What alternatives to __attribute__ exist on 64-bit kernels?

    - by Saifi Khan
    Hi: Is there any alternative to non-ISO gcc specific extension __attribute__ on 64-bit kernels ? Three types that i've noticed are: function attributes, type attributes and variable attributes. eg. i'd like to avoid using __attribute__((__packed__)) for structures passed over the network, even though some gcc based code do use it. Any suggestions or pointers on how to entirely avoid __attribute__ usage in C systems/kernel code ? thanks Saifi.

  • How to create "floating TextViews" in Android?

    - by Sotapanna
    Hi stackies, I'm programmatically putting various TextViews into a LinearLayout with a horizontal orientation. After 2h of research I couldn't find out how to tell Android not to squeeze all the TextViews in one line but instead to "float" non-fitting TextViews into the next line. I know there isn't something like actual "lines" in a LinearLayout, but how can I tell the TextViews to actually behave like floating DIVs from the HTML world? Thanks alot! Be well S.

  • Semantics of repeated acknowledgments in JMS

    - by Lajos Nagy
    Suppose I decide to call acknowledgment() on a JMS message several times. Say the first call fails (for non-permanent reason). Does the success of the second (or any subsequent) call guarantee that the message is now acknowledged? Is the exact behavior of acknowledgement() specified anywhere?

  • Drupal 6 CCK - Having a textbox appear when 'Other' is selected

    - by espais
    I have a special content-type that I have created, and one of the fields is a radio button list. The last element is named 'Other' and I would like to have a textbox appear and allow the user to enter in a non-defined value. Is this sort of capability provided by any sort of module, or is this something that needs to be coded by hand? (If so, would you mind pointing me in the correct direction?)

  • Do something before closing the browser window

    - by Adam Kiss
    Hello, we have an web-application built in flash (it's actually just getting built :D) where is very important to be notified, when user closes his window. Since it's in flash, we do not worry about Javascript, we do not support non-javascript users. What is the safest (meaning it's 100% sure it gets called) X-browser way to call php script to close session, make some db changes, etc.? Thank you

  • Sqlite3 and PDO problem with ORDER BY

    - by Maenny
    Hi, I try to use the SQL statement SELECT * FROM table ORDER BY column via an PDO-Object in PHP. Problem is, that I always get an error (Call to a member function fetchall() on a non-object - that means, the query did not return a PDO-object) when using the names of all columnname EXCEPT for ID. When I query SELECT * FROM table ORDER BY ID it works. ID is the PRIMARY INTEGER KEY, all other columns are TEXT or NUMERIC, neither of them would works with the ORDER BY clause. Any ideas?

  • How to unlock sa user in SQL Server 2012 if Windows Authentication doesn't work?

    - by Tony_Henrich
    I am logged in as an admin on the computer. For some reason I can't log into SQL Server 2012 which is running on the same machine. The SA user is locked out. SQL Server was installed when I was logged in into my company's domain. I am not logged into the domain when I try to log in to sql server. I don't know if this matters st all. However I expect to log using Windows authentication if I am in the administrator group?

  • Automatic repair software

    - by ADOConnection
    Do anyone knows any kind of apps or services for "taking care of servers"? (besides managed servers) There are hundreds of ways your server or application can stop working properly. Small things are easy to miss but usually easy to fix. Log overgrouth, configuration issues, etc. Of course there are best practice checklists, but its not a human task to check configuration best practices. Im sure it can be automated: some kind of agent can monitor all system settings, say what is right and wrong and give suggestions on how to make it right. I have to admin several servers and I need some kind of overview of overall situation. As well as a tool, that will fix problems automatically. Can you people suggest something? (I know its a little bit out of rules of SF, but I think this particular question is quite specific) It would be great to have something like http://stackoverflow.com/questions/1451319/asp-net-mvc-view-engine-comparison but for automation software.

  • C++ error message output format

    - by sub
    If I want to trigger an error in my interpreter I call this function: Error( ErrorType type, ErrorSeverity severity, const char* msg, int line ); However, with that I can only output Name error: Undefined variable in line 1 instead of Name error: Undefined variable 'someVariableName' in line 1 I'm working entirely with strings (except for the error messages as they all are constant at the moment), so sprintf won't work. What is the best way to create an efficient error function that can output a constant message combined with a string that describes which object, e.g.: a non-existing variable, triggered the error?

  • Zentyal Server : Setting up secure VPN Client

    - by JustShrey
    I have officially exhausted pretty much all my google-fu trying to set this up so I'm asking my question here. For the record, I am a mid level rookie who has played around with servers in his spare time but have never worked with Zentyal Server. Now, I have been able to set up the server as a gateway, with one Network card being external and the other facing the internal Network. The Internal network computers are able to access the internet without any issues. What I need to do is to setup a open-vpn client on the central server so that all Internet data goes though the secure VPN session. As far as I can see, I can't set up the vpn session through the web admin page. Could somebody point me in the right direction? How would I go about doing this? Regards Shreyas

  • What is the fastest / best Base64 en/decoder for Java ?

    - by mP
    Just found the MIG Base 64 utility but its over 6 years old since its last release. It would appear to be quicker than the Apache commons equivalent but I have yet to confirm by writing up an actual test. Has anyone verified its correctness which is always a worry. If someone takes a look at the methods, please note i a referring to the non fast methods which make assumptions trading possible correctness for pure speed.
