Can somebody help? I searched on the Internet and I found that there is a file httpcore-xx.jar that must be placed in apache tomcat lib directory. I tried that but it didn't work. I'm using ubuntu 14.04 LTS and eclipse. I also tried to clean my Project and build again. It didn't work. What I'm facing is that the page is loading on the web Browser but when I click on services the previous error comes up. The tutorial I'm trying to implement is http://codeoncloud.blogspot.gr/2012/12/create-java-web-service-in-eclipse_3982.html
回答1:
I had the same problem and successfully resolved it by copying xmlschema-core-*.jar form axis2-*/lib/ to my_project_root_directory/WebContent/WEB-INF/lib/.

I'm trying to create a simple web service too (configured: Dynamic Web Module 2.5), using: - Tomcat 8.0 and - Axis2 1.7.4 (axis2-1.7.4-war).
I'm getting the following errors:
[WARN] Web application uses org.apache.axis2.transport.http.AxisAdminServlet; please update web.xml to use org.apache.axis2.webapp.AxisAdminServlet instead
[INFO] Clustering has been disabled

The first problem was a [WARN]:
"[WARN] Web application uses org.apache.axis2.transport.http.AxisAdminServlet; please update web.xml to use org.apache.axis2.webapp.AxisAdminServlet instead"
Solution: I solved it updating web.xml as required.
The second problem was :
- java.lang.NoClassDefFoundError: org/apache/ws/commons/schema/resolver/URIResolver
- Caused by: java.lang.ClassNotFoundException: org.apache.ws.commons.schema.resolver.URIResolver
For some reason, when I created a new Dynamic Web Project configured with Axis2, the xmlschema-core-2.2.1.jar (axis2/WEB-INF/lib) was not imported to WebContent/WEB-INF/lib.
Solution: So I had to paste it there.
After that, other problem with jstl:
- This problem came up when I tried to login as a Admin on the WebService

Solution:
I downloaded these jars: - taglibs-standard-impl-1.2.5.jar and - taglibs-standard-spec-1.2.5.jar
from tomcat.apache.org/download-taglibs.cgi
So I had to pasted them in the WebContent/WEB-INF/lib too.
that's all folks. I hope it help.

IT also worked for me . axis2-1.7 and axis2-1.6 both worked for me just copied the xml-core to web/lib folder and build path and it worked.

This worked for me:
https://yiingw.wordpress.com/2018/02/12/axis2-java-lang-noclassdeffounderror-org-apache-ws-commons-schema-utils-namespaceprefixlist/
Reason: Axis2 1.7.x uses XmlSchema 2.2.x which is incompatible with Axis2 1.6.x and Eclipse does not copy the new version of XmlSchema to the web application.
Solution: Manually copy xmlschema-core-2.2.1.jar from $AXIS2_HOME/lib to the Eclipse project directory WebContent/WEB-INF/lib, close and reopen eclipse before generating web service client.
