hibernate+spring+eclipse: setting the path to HBM files

One issue I have constantly had trouble with is setting the directory of HBM files in a separate plugin than the main plugin in an eclipse+hibernate+spring RCP application. No path specification work except something like the following:

<property name="mappingDirectoryLocations">
 <list>
 <value>classpath*:/**/org/top/dirwithmappings</value>
 </list>
</property>

The standard examples in the spring and hibernate reference documents never worked for me. This classpath works even when the HBM and POJO files are in a different eclipse plugin. I believe that the hibernate references do not account for an OSGI environment although the syntax obviously helps across different jars.

zio and refilling a cache

zio and refilling a cache In some small web app server projects I sometimes need to cache some data to reduce latency and the impact of queries on a “weak” backend database. We can use alot of clever caching tools but sometimes I just need something quick and dirty. If you are using ZIO-style services, you may want the cache to be independent of other services and maintain the cache internally to the service environment. There are many ways to cache remote data, for example, you could also use ZQuery or the newer ZCache. Let’s assume that we want to do something simple: case class PeopleCache ( byId : Map [ UUID , Person ] = Map ( ) , last : LocalDateTime = LocalDateTime . now ( ) ) object PeopleCache : def createFromList ( people : List [ Person ] ) = ? ? ? trait Service : def search ( qstring : String ) : IO [ Exception , Option [ Person ] val live = ? ? ? class PeopleServiceImpl ( cache : RefM [ PeopleCache ] , db...

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...
