I've got an assembly in my framework, the purpose of which is to manage some data common to several applications that I am building. The assembly uses isolated storage to persist the data. The assembly itself happens to be a command-line .exe application and it can be executed directly as a tool to examine and make changes to the data....
Hi. I have a web application with some data in its datastore. I have just finished another version of it, in which i changed one of the persistent classes. Basically, there is a class called "Node" (which represents a node in a hierarchy tree), that used to have it's author as a private CmsUser author; and now it stores its author ...

I am in need of some further information. I am developing a small application which will be interacting with a PHP web application. The media server which we are incorporating with is extensible in Java. I need very little access to the database inside the plugin which we are developing, I only need to view rows in about 10% of the ta...
I've found myself starting to leverage checking persistence to get my models to 'work'. It seems convenient and correct to include a persistence check. On the other hand, it feels a little shady, as if I was being overly cautious or breaking the ORM abstraction in a small way. An example might be: class Shipment include DataMapper:Re...
Can anyone help me with following problem? I need to permanently save what I today have in arrays, to later use the data for calculations. I explain an example below. 1, I generate a long[][] which is far too big for my computers RAM. It is generated one row after the other. 2, I calculate something from my long[][] and save the result...
I have two objects a user and a role which I make persistant using JDO and googles app engine. The two datatypes are related to each other as unowned many to many relationship. I tried to model that much as in the gae-tutorial desribed as sets holding the key of the corresponding object. By the time I create my objects, those keys are nu...
Hi guys, I develop an application with Seam 2.2.0 on weblogic 10.3 In my components.xml, when I set my entityManager, I do this: <persistence:managed-persistence-context name="entityManager" auto-create="true" persistence-unit-jndi-name="OSSPortailDataSource" /> My DataSource is configured like this on weblogic: JNDI name: ...
I'm looking for some ideas to best persist an object over multiple page requests without the use of session variables, cookies, context cache, view state or a session database. I have a web form (ASPX) that will contain several user controls that will act as "pages", and these controls will be displayed in a one-at-a-time-manner: <uc1:...
I'm looking into implementing SNMPv3 as a requirement for monitoring a specific device on the network. As it is now, our project consists of a number of different Java classes that represent each device to be monitored on the network. Within each of these classes are a number of device-specific attributes that are needed in properly mon...
Short Version I have a list of ints that I need to figure out how to persist through Application Shutdown. Not forever but, you get the idea, I can't have the list disappear before it is dealt with. The method for dealing with it will remove entry's in the list. What are my options? XML? Background We have a WinForm app that uses ...
In my application,there are some application specific settings, which should be available to me , next time when my application starts up. In other words i want the data to be available across the sessions of an application cycle. Can this be achieved without using database(sqlite). ...
Hi there, I have a web page with a link to a url eg./customer/showitem?id=7, which displays details of a specific customer in a child-window using method showitem() in class customer. The method may set the value of a customer class attribute that controls an alert which is displayed when the page is loaded (eg. self.onloadalert="Warni...
Hi, I have 1 GB file of tables with data separated by columns. I have parsed it and stored in hash. Later on I am using this hash for my further work. But during developing my code each time I compile for testing the " parsing and storing into hash" is executed and which makes my program slow. Is there any way where I can store it so ...
I have a Graph object (this is in Perl) for which I compute its transitive closure (i.e. for solving the all-pairs shortest paths problem). From this object, I am interested in computing: Shortest path from any vertices u -> v. Distance matrix for all vertices. General reachability questions. General graph features (density, etc). T...
I'm trying to implement EJB persistence, but I'm having trouble deploying my application to JBoss. In my application I have the session bean TeamMgr, which looks like this: package ejb; import javax.ejb.Local; import javax.ejb.Remote; import javax.ejb.Stateless; import javax.persistence.EntityManager; import javax.persistence.Persisten...
I understand that it's better if objects are not responsible for their own persistence (makes testing the objects easier, plus separation of responsibilities), but then what object should handle persistence of domain objects, and what should the persistence API look like at a high-level? ...
Sorry that the title isn't exactly obvious, but I couldn't word it better. We are right now using a conventional DB (oracle) as our job queue, and these "jobs" are consumed by some number of nodes (machines). So the DB server gets hit by these nodes, and we have to pay a lot for the software and hardware for this database server. N...
Is there a way to prevent a WCF 3.5 workflow from being persisted? I have an issue where some items in the workflow cannot be serialized so I need to block persistence. Is there a way do this in .NET 3.5? ...
I am having problems persisting domain objects where I have a many-to-many relationship with a join table class A{ String name static hasMany = [bs:B] } class B{ String surname static belongsTo=A static hasMany=[as:A] } A a = new A(name:'Test') B b = new B(surname:'user') a.addToBs(b) a.save(flush:true) Then what I would expec...
