Eclipse RCP+Spring+EMF+Teneo

One issue for using these technologies together is using spring and the teneo HbSessionDataStore versus the LocalSessionFactoryBean that is seen in most spring tutorials.

To use the teneo approach, you need to define your beans and DAOs like the following:

<!-- Should get persistence properties and hibernate properties from property files. -->
    <bean id="sessionFactory" scope="singleton" lazy-init="true"
        class="org.eclipse.emf.teneo.hibernate.HbSessionDataStore"
        p:name="MyDataStore">
        <property name="EPackageClasses">
            <util:list>
                <value>org.yourmodel.impl.YourPackageImpl</value>
                <value>org.yourmodel2.impl.Your2PackageImpl</value>
            </util:list>
        </property>
    </bean>
   
    <util:constant static-field="org.yourmodel.YourFactory.eINSTANCE"/>
    <bean id="contactDao" scope="singleton" lazy-init="true"
        factory-bean="org.yourmodel.YourFactory.eINSTANCE"
        factory-method="createDao"
        p:sessionFactory-ref="sessionFactory"/>
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>
You can access the eINSTANCE through the interface directly. There are other methods to get access to the instance and give it a shorter bean name using FieldRetrievingFactoryBean (or something like that). Do not forget your namespace definitions on the beans element.

Another way to create beans, especially if you have alot of them, is to create your own spring context local copy of the factory using 

<bean id="yourFactory"
  class="yourPackage.impl.MyFactoryImpl"
 factory-method="init">


And then use 

<bean id="yourNewBean" factory-bean="yourFactory" factory-method="createYourBean" />

where createYourBean is following the creator approach implemented by EMF.

quick note on scala.js, react hooks, monix, auth





















            quick note on scala.js, react hooks, monix, auth          Reactjs hooks finally came out of preview in a recent version of React. scalajs-reaction  has had support for hooks since they were in preview.  React hooks seem like the hot new thing but for me the question is, do hooks help improve your code by improving maintainability, time to market, TCO, etc.?  Let’s take a look using authentication as an example and employ monix , a reactive observable framework that also builds on cats .  We will assume we are building a SPA.  Does it improve your code and make your application & development experience  better?  Auth  Auth processing can be complex. Many react auth examples you find in blogs like to show how to use “react-routing” and “auth” as a switch that determines which routes are protected or unprotected. Protected routes show application specific data. Unprotected routes show login content . Based on storing a “User” object in the browser session/local storage, th...

attributes with react and typescript.md





















If you use typescript with react you may wonder what the right signature is for your “properties” interface.  Obviously, your component will have few to many specific properties that reflect your domain. However, you may wish to also provide for the ability to add other attributes, such as those valid for a div property. In other words, you want to extend your props interface with that of the properties from a div element. How do you do that?  There are really two issues:   How do you extend your props interfaces  How do you filter the props once you receive them to just those that apply.   Extend Your Prop Interface or Use Sum Types  It’s not uncommon to see  interface  Props  {   className ? :  string   yourProp ? :  number  }   with the idea of using it in class MyComponent extends React.Component<Props, any>  somewhere. If your component will have an outer div, you may also pass in a react element so that its configurable. But let’s say your outer element is a div and you wan...

zio environment and modules pattern: zio, scala.js, react, query management





















            zio environment and modules pattern: zio, scala.js, react, query management          This blog covers a zio-based fetch design for scala.js, react web applications. It heavily uses the zio “environment” feature to help motivate a point of view on the modules pattern in effect systems. At the end, I summarize some thoughts on ergonomics and complexity.  This blog assumes a basic knowledge of zio and react. scala.js is just like scala so you mostly already know scala.js.  This blog is a follow-on to previous blogs: https://appddeevvmeanderings.blogspot.com/2019/10/scalajs-react-fetcher-hook_48.html  and https://appddeevvmeanderings.blogspot.com/2019/11/scalajs-and-react-suspense.html .  I have been keeping an eye on and culling ideas from typscript/javascript fetching libraries that address query management concerns. The formulation below incorporates some of those concerns but does not try to comprehensively duplicate well established javascript libraries. I only care about ...
