    "Seam 3 is collection of modules and developer tools based on the Java EE platform. The modules are portable extensions to CDI that integrate with other technologies to extend the core Java EE functionality. These modules bring you many of the beloved features and integrations from Seam 2 (security, internationalization, JSF, rules, business process management) and also branch out into new areas. IDE support is provided by the JBoss Tools Eclipse plugins. Before diving in, get up to speed with the status and direction of Seam 3. Also be sure to check out the latest news at the bottom of the page. "

    From a technical standpoint Ext GWT and SmartGWT are quite equal apart from the fact that Smart has more to offer on the server side. Vaadin with its complete different apprach (not from the programming style but from runtime behavior) needs to be compared in a different fashion. Things like GUI responsiveness and overall performance must be carefully checked. But on the pro side you have a very small js client with vaadin which results in fast startup in the browser. On the other hand, our product is a business product and we are planing to rewrite the AdminConsole. This is something that will be used in intranets in 95% of the time. It doesnt make much of a differnece if you load 100k or 1Mb from inside the LAN.

    Database Change Management You never develop code without version control, why do you develop your database without it? Liquibase is an open source (Apache 2.0 Licensed), database-independent library for tracking, managing and applying database changes. It is built on a simple premise: All database changes are stored in a human readable yet trackable form and checked into source control. Liquibase Supports: Extensibility Merging changes from multiple developers Code branches Multiple Databases Managing production data as well as various test datasets Cluster-safe database upgrades Automated updates or generation of SQL scripts that can be approved and applied by a DBA Update rollbacks Database "diff"s Generating starting change logs from existing database

    Apache CXF is an open source services framework. CXF helps you build and develop services using frontend programming APIs, like JAX-WS and JAX-RS. These services can speak a variety of protocols such as SOAP, XML/HTTP, RESTful HTTP, or CORBA and work over a variety of transports such as HTTP, JMS or JBI. CXF includes a broad feature set, but it is primarily focused on the following areas: Web Services Standards Support: CXF supports a variety of web service standards including SOAP, the WS-I Basic Profile, WSDL, WS-Addressing, WS-Policy, WS-ReliableMessaging, WS-Security, WS-SecurityPolicy, WS-SecureConverstation, and WS-Trust (partial). Frontends: CXF supports a variety of "frontend" programming models. CXF implements the JAX-WS APIs (TCK compliant). CXF JAX-WS support includes some extensions to the standard that make it significantly easier to use, compared to the reference implementation: It will automatically generate code for request and response bean classes, and does not require a WSDL for simple cases. It also includes a "simple frontend" which allows creation of clients and endpoints without annotations. CXF supports both contract first development with WSDL and code first development starting from Java. For REST, CXF also supports a JAX-RS (TCK compliant) frontend. Ease of use: CXF is designed to be intuitive and easy to use. There are simple APIs to quickly build code-first services, Maven plug-ins to make tooling integration easy, JAX-WS API support, Spring 2.x XML support to make configuration a snap, and much more. Binary and Legacy Protocol Support: CXF has been designed to provide a pluggable architecture that supports not only XML but also non-XML type bindings, such as JSON and CORBA, in combination with any type of transport. To get started using CXF, check out the downloads, the user's guide, or the mailing lists to get more information!

    Java Topic / Java tutorial The final keyword helps in making a variable unmodifiable after the initialization. If a variable is defined with final keyword, then it can not be modified after the initialization. This kind of check prevents the developers from accidentally modifying a variable, a method or a class.

1. Working with Spring Data Repositories - 0 views

java Spring Data

shared by anonymous on 29 Oct 13 - No Cached
  • Typically, your repository interface will extend Repository, CrudRepository or PagingAndSortingRepository. Alternatively, if you do not want to extend Spring Data interfaces, you can also annotate your repository interface with @RepositoryDefinition
  • It allows quick query definition by method names but also custom-tuning of these queries by introducing declared queries as needed.
  • CREATE_IF_NOT_FOUND (default)CREATE_IF_NOT_FOUND combines CREATE and USE_DECLARED_QUERY.
  • ...21 more annotations...
  • the first By acts as delimiter to indicate the start of the actual criteria
  • The mechanism strips the prefixes find…By, read…By, and get…By from the method and starts parsing the rest of it
  • you can define conditions on entity properties and concatenate them with And and Or
  • The introducing clause can contain further expressions such as a Distinct to set a distinct flag
  • List<Person> findByEmailAddressAndLastname(EmailAddress emailAddress, String lastname); // Enables the distinct flag for the query List<Person> findDistinctPeopleByLastnameOrFirstname(String lastname, String firstname); List<Person> findPeopleDistinctByLastnameOrFirstname(String lastname, String firstname); // Enabling ignoring case for an individual property List<Person> findByLastnameIgnoreCase(String lastname); // Enabling ignoring case for all suitable properties List<Person> findByLastnameAndFirstnameAllIgnoreCase(String lastname, String firstname); // Enabling static ORDER BY for a query List<Person> findByLastnameOrderByFirstnameAsc(String lastname); List<Person> findByLastnameOrderByFirstnameDesc(String lastname);
  • You can combine property expressions with AND and OR. You also get support for operators such as Between, LessThan, GreaterThan, Like for the property expressions
  • AllIgnoreCase
  • IgnoreCase
  • The resolution algorithm starts with interpreting the entire part (AddressZipCode) as the property and checks the domain class for a property with that name (uncapitalized). If the algorithm succeeds it uses that property. If not, the algorithm splits up the source at the camel case parts from the right side into a head and a tail and tries to find the corresponding property, in our example, AddressZip and Code.
  • he infrastructure will recognize certain specific types like Pageable and Sort to apply pagination and sorting to your queries dynamically
  • Pageable
  • Sort sort
  • The first method allows you to pass an org.springframework.data.domain.Pageable instance to the query method to dynamically add paging to your statically defined query. Sorting options are handled through the Pageable instance too
  • <repositories base-package="com.acme.repositories" />
  • Spring is instructed to scan com.acme.repositories and all its subpackages for interfaces extending Repository or one of its subinterfaces. For each interface found, the infrastructure registers the persistence technology-specific FactoryBean to create the appropriate proxies that handle invocations of the query methods. Each bean is registered under a bean name that is derived from the interface name, so an interface of UserRepository would be registered under userRepository
  • This postfix defaults to Impl.Example 1.12. Configuration example<repositories base-package="com.acme.repository" /> <repositories base-package="com.acme.repository" repository-impl-postfix="FooBar" />The first configuration example will try to look up a class com.acme.repository.UserRepositoryImpl to act as custom repository implementation, where the second example will try to lookup com.acme.repository.UserRepositoryFoo
  • To exclude an interface that extends Repository from being instantiated as a repository instance, you can either annotate it with @NoRepositoryBean or move it outside of the configured base-package.
  • ]In general, the integration support is enabled by using the @EnableSpringDataWebSupport annotation in your JavaConfig configuration class.
  • @Configuration @EnableWebMvc @EnableSpringDataWebSupport class WebConfiguration { }
  • In case you need multiple Pageables or Sorts to be resolved from the request (for multiple tables, for example) you can use Spring's @Qualifier annotation to distinguish one from another
  • Spring HATEOAS ships with a representation model class PagedResources that allows enrichting the content of a Page instance with the necessary Page metadata as well as links to let the clients easily navigate the pages.

  • IBM still runs basic physics last I checked and has deep resources in research to throw at any problem it wants
  • with more money and influence than nearly all of their competitors
  • both companies are highly invested in Java, which means it will continue, but in what form we have no idea
  • ...7 more annotations...
  • IBM is not interested in Sun software but in the Sun hardware and storage
    • Baron M
      Baron M on 01 Apr 09
       
      different perspective
  • pose a number of integration issues for IBM Software Group
  • expect that IBM will take the long view, that an open, flourishing ecosystem around Java will be the tide that lifts all boats
  • some observers say IBM would do well to merge the best parts of both platforms into one.
  • IBM has been a proponent of open standards in the Java ecosystem, and I expect that will continue
  • shed a lot of the weaker products (and a significant number of redundant staff)

      conclusion: SUN and JCP suck, so they deserve this. God bless java and java dependent vendors.

java Serializable serialVersionUID

shared by Rinav G on 09 Nov 10 - Cached
  • private static final long serialVersionUID = 1L
  • and it is still there even after the program finished. Let’s see if we can read that file once again, this time without creating it first.
  • Now, let’s see what happens, when we change the serialVersionUID value and try to deserialize once again our file. Change the line 2 in the class SerializeMe so that serialVersionUID contains now 2 instead of 1:
  • ...13 more annotations...
  • serialVersionUID = 2L;
  • static final
  • Exception in thread "main" java.io.InvalidClassException:
  • As you can see, this time the deserialization didn’t go well. ObjectInputStream complained about the serialVersionUID being changed.
  • How does he know that it changed? If serialVersinUID is static, then it should not have been serialized in the first place, and there should be no information about the previous value 1 during the deserialization, right? Well, serialVersionUID is an exception to the rule that “static fields don’t get serialized”.
  • Moreover, if there is no serialVersionUID officially declared in the class to be serialized, compiler automatically adds it with a value generated based on the fields declared in the class.
  • The deserialization of that object does not necessarily have to occur exactly after serialization. It can occur after a few months or on a completely different JVM
  • there is a chance that the class declaration has changed between serialization and deserialization.
  • It checks if the data read from the input stream is compatible with the current definition of the class.
  • when the visibility of a field changes, the serialVersionUID changes too.
  • sometimes you just want for some reason to forbid deserialization of old serialized objects,
  • you might tend to write it once for every serializable class ( or have it generated by the IDE ) and forget about it. WRONG !!!
  • If you write it once and don’t take care to update it when necessary, you loose all the merits of serialVersionUID.

    Security is getting more important every day. You might not be familiar with JAAS, JAAC, and JASPIC, but these standard Java EE APIs remained untouched until the Java EE Security API for Java EE 8. Check why the Java EE 8 Security API is so important.
