    Shrinkwrap provides a simple mechanism to assemble archives like JARs, WARs, and EARs with a friendly, fluent API. JavaArchive archive = ShrinkWrap.create(JavaArchive.class,"archive.jar")    .addClasses(MyClass.class,MyOtherClass.class)    .addResource("mystuff.properties"); From there you may deploy directly into any supported integration container like JBoss EmbeddedAS, GlassFish v3 Embedded, Jetty, or OpenEJB.  Or perhaps you'd like to export the archive to a file or exploded directory structure.  Maybe you'd prefer to serialize it over the network to a remote host.  The possibilities are limitless. To boot, ShrinkWrap is the supported deployment mechanism of the Arquillian project, and together we render the testing of true enterprise components amiable as a puppy.  Where Java EE brought a POJO programming model to application development, we've brought it to testing.  You handle your business logic; we'll do the rest. To foster community participation, the majority of documentation and examples are available through our Wiki. Releases are available either via our Downloads section, or through the JBoss Maven Repository, which we recommend is configured in ${userHomeDir}/.m2/settings.xml:

Chapter 6. HTTP Caching - 0 views

  •  
    HttpClient Cache provides an HTTP/1.1-compliant caching layer to be used with HttpClient--the Java equivalent of a browser cache. The implementation follows the Decorator design pattern, where the CachingHttpClient class is a drop-in replacement for a DefaultHttpClient; requests that can be satisfied entirely from the cache will not result in actual origin requests. Stale cache entries are automatically validated with the origin where possible, using conditional GETs and the If-Modified-Since and/or If-None-Match request headers. HTTP/1.1 caching in general is designed to be semantically transparent; that is, a cache should not change the meaning of the request-response exchange between client and server. As such, it should be safe to drop a CachingHttpClient into an existing compliant client-server relationship. Although the caching module is part of the client from an HTTP protocol point of view, the implementation aims to be compatible with the requirements placed on a transparent caching proxy. Finally, CachingHttpClient includes support the Cache-Control extensions specified by RFC 5861 (stale-if-error and stale-while-revalidate).

jmockit - A capable and elegant developer mock testing toolkit for Java - Google Projec... - 0 views

  •  
    "JMockit allows developers to write unit/integration tests without the testability issues typically found with other mocking APIs. Tests can easily be written that will mock final classes, static methods, constructors, and so on. There are no limitations. The JMockit mocking API is simple, consistent, and minimal. There are no special methods or annotations that need to be used in test code, apart from those that really make sense. In general, the use of JMockit APIs for mocking leads to test code that is better structured and more readable. "

JavaBlogging » What is serialVersionUID? - 2 views

  • 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.

EasyMock - Mock Objects for interfaces & objects by generating them on the fly using Ja... - 10 views

  •  
    "EasyMock provides Mock Objects for interfaces (and objects through the class extension) by generating them on the fly using Java's proxy mechanism. Due to EasyMock's unique style of recording expectations, most refactorings will not affect the Mock Objects. So EasyMock is a perfect fit for Test-Driven Development. EasyMock is open source software available under the terms of the Apache 2.0 license. Development, downloads and issue tracking are hosted on SourceForge. "
