I am new to this forum. I am trying to make an application using spring 3.2.6 and tomcat 7.0. I have added all the necessary jars in the WEB-INF/lib folder. The DispatcherServlet and ContextLoaderListener is properly configured in the web.xml. The same application was working fine with spring 3.0.2 version. Now when I am trying to open the jsp page, it is giving me below error:

HTTP Status 500 - org/springframework/web/servlet/HttpServletBean : org/springframework/context/EnvironmentAware

type Exception report

message org/springframework/web/servlet/HttpServletBean : org/springframework/context/EnvironmentAware

description The server encountered an internal error that prevented it from fulfilling this request.

exception

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.42 logs.

The jar

spring-context-3.2.6.RELEASE

is already added in the classpath. I am able to open the class file also from the Eclipse. But I don't understand why it is giving class not found error at run time. I tried to search it on google but didn't find exact the solution. Thanks in advance.

The class org.springframework.web.servlet.HttpServletBean is part of spring-webmvc. You will need to add that library to your classpath as well. You can get it here.

  • Thanks for the comment. But I have already added spring-webmvc-3.2.6.RELEASE in the WEB-INF/lib folder. – DDP Dec 29 '13 at 19:51
  • @DDP Right click your project, select `Properties` and go to `Deployment Assembly` and `Build Path`. Are you jars added? – Sotirios Delimanolis Dec 29 '13 at 19:54
  • Yes. jars are added there. Even I tried by adding both the jars as external jars using Java >Build Path -> Libraries -> Add External JARs But still it gives the same error. – DDP Dec 29 '13 at 20:03
  • @DDP Can you add an image (or just write it up) of your directory structure? – Sotirios Delimanolis Dec 29 '13 at 20:04
  • I am unable to upload the image so I giving you the hierarchy in brief. It has WebContent -> WEB-INF ->lib. There are several other packages under src folder for model and controllers. But all the jars are placed in the lib folder – DDP Dec 29 '13 at 20:19
  • @DDP Try deleting your Tomcat server instance and creating a new one. – Sotirios Delimanolis Dec 29 '13 at 20:21

If it works for an older version(as you say), What I guess there are some places you have old jar in the path, which mess up the jar dependency I will suggest you do a full disk search to find out all your spring jar location and clean them up. BTW: you can try to add jar to tomcat/lib to try also (it is not proper practice, but this can help to find out whether it is path related issue).

  • Thanks for the hint. There were spring jars in the plugins folder of the eclipse installation. I tried removing those but didn't work. Then as per your suggestion, just copied the jar in the tomcat/lib folder and the error was not coming. But in this way I had to add all the jar which was not proper solution. Finally I just created new workspace and configure the project again which solved the issue. But I am still not sure about the error cause. Anyway, Thank you. – DDP Dec 30 '13 at 18:19

EnvironmentAware is located in the spring-context-3.1.1.RELEASE.jar, so you are missing that one.

Also recheck your Maven POM file so that you are not missing any other Spring library, like spring-web, spring-webmvc (you may have these since the DispatcherServlet class if found), spring-orm if you use an ORM like Hibernate, spring-jms if you use JMS, etc.

I had this problem. I solved it by adding the jar:

org.springframework.context-3.1.0.RELEASE.jar

to both the build path and as a maven dependency (java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet error)

Hope it helps
