• JPA: what is the proper pattern for iterating over large result sets?

  - by Caffeine Coma

  Let's say I have a table with millions of rows. Using JPA, what's the proper way to iterate over a query against that table, such that I don't have all an in-memory List with millions of objects? I suspect that the following will blow up if the table is large: List<Model> models = entityManager().createQuery("from Model m", Model.class).getResultList(); for (Model model : models) { // do something with model } Is pagination (looping and manually updating setFirstResult()/setMaxResult()) really the best solution?

• Letting users try your web app before sign-up: sessions or temp db?

  - by Mat

  I've seen a few instances now where web applications are letting try them out without you having to sign-up (though to save you need to of course). example: try at http://minutedock.com/ I'm wondering about doing this for my own web app and the fundamental question is whether to store their info into sessions or into a temp user table? The temp user table would allow logging and potentially be less of a hit on the server, correct? Is there a best practice here?

• PHP ingore case sensitivity when comparing array values

  - by dan.codes

  I have to modify some code in a application I am working on that is using the array_diff($array1,$array2) method. The problem I am having is it is case sensitive and I need to have it return the correct value if the array values match even if the case is different. I don't want to change the case to lowercase because I need the value returned to keep its case. I'm a little confused as the best method to do this.

• How to build and deploy Python web applications

  - by sverrejoh

  I have a Python web application consisting of several Python packages. What is the best way of building and deploying this to the servers? Currently I'm deploying the packages with Capistrano, installing the packages into a virtualenv with bash, and configuring the servers with puppet, but I would like to go for a more Python based solution.

• How to dynamically change the content of a facet in a custom component?

  - by romaintaz

  Hello, Let's consider that I want to extend an existing JSF component, such as the <rich:datatable/>. My main requirement is to dynamically modify the content of a <f:facet>, to change its content. What is the best way to achieve that? Or where is the best place in the code to achieve that? In my faces-config.xml, I have the following declaration: <faces-config> ... <component> <component-type>my.component.dataTable</component-type> <component-class>my.project.component.table.MyHtmlDataTable</component-class> </component> ... <render-kit> <render-kit-id>HTML_BASIC</render-kit-id> <renderer> <component-family>org.richfaces.DataTable</component-family> <renderer-type>my.renderkit.dataTable</renderer-type> <renderer-class>my.project.component.table.MyDataTableRenderer</renderer-class> </renderer> ... Also, my my-project.taglib.xml file (as I use Facelets) looks like: <facelet-taglib> <namespace>http://my.project/jsf</namespace> <tag> <tag-name>dataTable</tag-name> <component> <component-type>my.component.dataTable</component-type> <renderer-type>my.renderkit.dataTable</renderer-type> </component> </tag> So as you can see, I have two classes in my project for my custom datatable: MyHtmlDataTable and MyDataTableRenderer. One of my idea is to modify the content of the <f:facet> directly in the doEncodeBegin() method of my renderer. This is working (in fact almost working), but I don't really think that's the better place to achieve my modification. What do you think? Technical information: JSF 1.2, Facelets, Richfaces 3.3.2, Java 1.6
