osgi

To develop plug-ins or RCP programs based on Eclipse, you need to understand some basic knowledge, such as osgi, SWT, jface, EMF, and GMF. Osgi Introduction Osgi is a dynamic model system for Java. The osgi service platform provides services to Java, which makes Java the preferred environment for software integration a

three isolation problems:InterAction (Interface) Isolation,Program access isolationAndData isolation(Note that these three problems correspond to the three technical content of the enterprise application service component respectively ). Interaction isolation makes enterprise users have to access different interfaces. Code Access Isolation leads to point-to-point integration and various non-functional problems such as performance, transactions, and asynchronous processing, data Isolation leads

As a beginner, it's still a bit of a hassle to build a spring.dm web development environment. I met n more trouble, took a lot of detours. This article introduces 2 kinds of relatively simple construction of SPRING.DM OSGi Web development environment.The first of these methodsSimilar to the previous article, please step here: SPRING.DM version HelloWorldFirst of all, refer to the Spring-osgi-2.0.0.m1 folder

In the first part of this series, an overview of Eclipse and plug-ins, basic concepts of plug-in development, OSGi, and SWT are briefly introduced.Architecture of the 1.EclipseEclipse is widely used as a Java IDE (integrated development environment), but in essence Eclipse is a platform that integrates a variety of development tools. Therefore, it adopts the plug-in architecture technology which can add various functions freely. The basic architecture

, or by CLASSPATH environment variables. The Java class loader scans this path when parsing classes at runtime, whether the process is statically (compiled into code) or dynamically (using reflection and Class.forName ()). However, multiple class loaders can be used at run time, and Web application engines such as jetty and Tomcat use multiple ClassLoader to support application hot deployment. In OSGi, each bundle has its own class loader. Classes th

Adobe FlexAs the front-end client. it aims to achieve this purpose by providing first-class support for using the open source Adobe blazeds project and its powerful remoting and messaging facilities in combination with the familiar spring programming model.

development platform based on the concept of MDA. However, with the increasing requirements of business department development flexibility, xplatform becomes increasingly inadequate in terms of customization and modularization. After the technical strategy was adjusted in March, I started a huge xplatform reconstruction plan, and I was assigned to consider the underlying architecture reconstruction and service framework design. At that time, when we first considered modularize the underlying la

of 1999, CICS is enabled to control the JVM pool, where only one Java-based CICS transaction is assigned to the JVM at a time (and therefore requires a JVM pool). In CICS TS V4.1 (June 2009), CICS introduced Jvmserver resources. The resource is a JVM in which multiple Java-based CICS transactions can be dispatched concurrently. Initially, only system functions can use Jvmserver. However, since the CICS TS V4.2 (June 2011), Jvmserver can run Java programs that use the Apache Software Foundation

After the previous analysis of the Distributed Service Framework blog, the formal renaming of the previous series of distributed service framework based on OSGi (by the way of the Distributed service framework to use DSF abbreviation), because it has been decided to implement based on SPRING-DM, why, And why must it be SPRING-DM, instead of just saying spring? Today is SPRING-DM 1.0 release of the big day, not easy ah, did so long, specific how has n

ClassLoader to load classes, such as Serviceloader implementations Using the thread context class loader to load classes, it is important to ensure that the class loader between multiple threads that need to communicate should be the same, preventing the type conversion exception from being caused by different classloader (classcastexception) 4. Tomcat class loading mechanism Different applications use different WebApp class loaders to achieve the effect of application isola

tests are in another solution when code changes are made, our continuous integration system will automatically build AppStore, SDK installation package and unit test code and execute unit test. If an exception occurs, it will send a system email, you can see our product quality assurance system in [Product Development Experience Summary] the tip of the iceberg behind software products. The Code consists of five parts: (1) UIShell. OSGi and UIShell.

a new protected method to Java.lang.ClassLoader after the class was forward compatible JDK1.2 Findclass ()。 The second is caused by the defect of the model itself, the parent delegation model solves the basic class unification problem of each class loader well, but if the basic class is back to the user's code, it is not suitable. Therefore, a thread context class loader was added (thread contextual ClassLoader). This classloader can be set by the Setcontextclassloader method of the Java.lan
