Folks- I'm following an example from Craig Walls' "Spring in Action 3" (MEAP edition) on Tomcat 7.0.10. Getting a compiler error in eclipse on the following import:
import javax.inject.In开发者_如何学Pythonject;
The error message is:
The import javax.inject cannot be resolved
I understand javax.inject is part of Java EE 6, is Tomcat 7 not Java EE 6 compliant? I have all the jars in $CATALINA/lib copied to my WEB-INF/lib directory, also did a manual search (jar -tvf) but couldn't find this package.
Any help will be greatly appreciated. Thanks.
Tomcat is a servlet container, therefore it has nothing to do with JSR-330 (javax.inject
).
If you want to use JSR-330 annotations, you need to add JSR-330 jar to the classpath.
If you use Maven, you can use the following pom.xml and it will automatically download the Spring and Java EE jars for your project:

Tomcat is just a Servlet container and is not Java EE 6 compliant. You can use GlassFish 3.1 (glassfish.org) which is a fully Java EE 6-compliant app server with clustering and high availability.
