the form of patterns and guidelines. These guidelines and patterns can be found in the book [Kas02], which is also available online at [Blr07]. However, the skeleton code is not distributed separately. There is a sample application available, that was created by the engineers of Blueprints and follows their guidelines. Blueprints also relies heavily on the J2EE specifications [J2E07]. Blueprints can be seen as an extension to the J2EE specifications, which means that in the feature diagram features from both J2EE in general and Blueprints will be displayed. However, only the features that Blueprints add count for Blueprints. If we would add the features from J2EE, we would be comparing J2EE + Blueprints, not just Blueprints. The features are displayed however, to leave no gaps in the features, since some rely on base code from J2EE. Spring does this as well, but created layers above each J2EE feature so no J2EE feature are visible. The initial version was created by examining the reference guide at [Blr07] and several other online resources. After this, the diagram was discussed with employees within Everest who have experience with the pet store application. Furthermore, the diagram has been further refined in the second step when the package structure of the demo application was examined in detail. Note that we do not claim completeness for correctness for the features listed as features from J2EE. These features are nearly added to provide a more cohesive picture. Step 2, abstraction types From most of the package names, the feature was directly derivable. For example, org.framework.aop.aspectj , the resulting feature is aspectJ under AOP support in the tree. For other packages the JavaDoc and reference guide have been used. The packages to supply to the tools have been based upon relevance, mainly samples and tests have been left out. These do not influence frameworks features. The packages used for Spring are: /aspectJ/src /dist /lib /src /target /tiger/src The packages for Blueprints are: /src/waf /src/components/encodingfilter /src/components/mailer /src/components/servicelocator /src/components/signon /src/components/uidgen This list has been composed by taking the reusable component from both frameworks. For Spring we only had to remove tests and mock code. For Blueprints we consulted the employees of Everest to clarify which packages where reusable code and which belonged exclusively to the pet store application. These metrics were gathered using the following parameters on the tools: javancss.Main -recursive -gui –all PATH jdepend.xmlui.JDepend -file jdepend.xml PATH Where path are the packages mentioned above. The sources need to be compiled as well, make sure that only the given path is compiled to avoid tests and mock code in the packages, which could change the metrics considerably.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
