As noted inJARs and Eclipse Build Path, the WebApp Library is one of the op=
tional groupings of library organization in theEclipse project and is parti=
cularly germane and useful to the Dynamic WebProject (as opposed to a plain=
 Java Project).

The IDE builds projects using project source files as well as JARs that are=
 stored in the project or outside the project as J2EE libraries. Multiple p=
rojects can reference a single copy of a J2EE library stored on the server =
alleviating the need to create separate copies of the library in each proje=
ct.

This guide shows you how to create a multi-module project with Spring Boot.=
 The project will have a library jar and a main application that uses the l=
ibrary. You could also use it to see how to build a library (that is, a jar=
 file that is not an application) on its own.

The library will provide a MyService class that can be used by applications=
. The following listing (from library/src/main/java/com/example/multimodule=
/service/MyService.java) shows the MyService class:

To make it configurable in the standard Spring Boot idiom (with application=
.properties), you can also add a  ConfigurationProperties class. The Servic=
eProperties class (from library/src/main/java/com/example/multimodule/servi=
ce/ServiceProperties.java) fills that need:



You need not do it this way. A library might merely provide pure Java APIs =
and no Spring features. In that case, the application that consumes the lib=
rary would need to provide the configuration itself.

You will want to write unit tests for your library components. If you provi=
de re-usable Spring configuration as part of the library, you might also wa=
nt to write an integration test, to make sure that the configuration works.=
 To do that, you can use JUnit and the  SpringBootTest annotation. The foll=
owing listing (from library/src/test/java/com/example/multimodule/service/M=
yServiceTest.java) shows how to do so:

The main class in the application can be a  RestController that uses the Se=
rvice from the library to render a message. The following listing (from app=
lication/src/main/java/com/example/multimodule/application/DemoApplication.=
java) shows such a class:

You need to provide a message for the service in the library in application=
.properties. In the source folder, you need to create a file named src/main=
/resources/application.properties. The following listing shows a file that =
would work:

Having these new J2EE preferences set by default as of RAD 7.0.0.1 was caus=
ing these library containers to be added to the .classpath files of RAD v6 =
and earlier J2EE projects unexpectedly, when J2EE Module Dependencies are s=
pecified and causing unexpected build errors such as "Duplicate classpath e=
ntry" error. In short the .classpath file had older individual entries for =
items that are also specified in J2EE container libraries.

J2EE tools/build should not modify .classpath automatically. This especiall=
y affects projects with build tools/ant tasks that parse .classpath for the=
 traditional eclipse/java src/output information:


The EAR, EJB and WEB Eclipse project source for this EclipseLink OC4J tutor=
ial will be available online at the following locations. These 3 projects m=
ust be imported along with the jpa core eclipselink project.

2. when i want to use the remote debugging via Java Remote App and Server A=
PPxyz.scm.azurewebsites.net Port 50148 eclipse throws the error "Failed to =
connect to remote VM. Connection refused. Connection time out: connect

Since the url i.e. dl.microsoft.com/eclipse/ is not accessible, unable to i=
nstall the azure tool kit. Is there any other url to refer to, or is there =
any other older stable version? I guess the one expected at dl.microsoft.co=
m/eclipse/ is 3.5.0.

I checked out your example. It seems that the License project is not marked=
 as a web project. Just apply the eclipse-wtp on it, start the project sync=
hronization (right click > Gradle > Refresh Gradle Projects) and your proje=
ct will appear amongst the web modules:


The library-ref element and its sub-elements specify to Oracle WebLogic Ser=
ver that the JSTL 1.2 library should be used as a shared library. The advan=
tage of using a shared library in this manner is that the library does not =
need to be included in each individual WAR or EAR file deployed to the serv=
er.
