Jersey : How to prevent Conflicting URI templates with other web services in the same web app

I am trying to introduce Jersey web service into a web application that has other web services (such as Apache CXF in it) in it. So I added Jersey servlet to my web.xml..
<servlet>
<servlet-name>jersey-servlet</servlet-name>
<servlet-class>
com.sun.jersey.spi.spring.container.servlet.SpringServlet
</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.freedomoss.crowdcontrol.api</param-value>
</init-param>
<init-param>
<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jersey-servlet</servlet-name>
<url-pattern>/service/*</url-pattern>
</servlet-mapping>
During intiliazation this servlet gives the following error about conflicting URL templates...
INFO: Registering Spring bean, restApiService, of type com.mycompany.ws.RestApiService as a root resource class
Mar 12, 2015 11:07:42 PM com.sun.jersey.spi.spring.container.SpringComponentProviderFactory registerSpringBeans
SEVERE: The following errors and warnings have been detected with resource and/or provider classes:
SEVERE: Conflicting URI templates. The URI template / for root resource class com.mycompany.ws.RestApiService and the URI template / transform to the same regular expression (/.*)?
When I look in the code of this RestApiService, I see..
#Path("/")
#Service
public class RestApiService extends AbstractRestService {
Since this other web service is being used elsewhere in the application I cannot change the value of 'Path' although doing so does solve my problem
What else can I do? Can I somehow tell Jersey Servlet not to register this other web service "as a root resource class"?
My goal is to make Jersey work along with this other web service and not change the latter in any way.

Tomcat unable to parse web.xml, no error at mentioned code point

I am using Jersey for my web service, and this is how my web.xml looks like:
<?xml version="1.0" encoding="UTF-8"?>
<web-app>
<servlet>
<servlet-name>jersey</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>

</init-param>**
<init-param>

</servlet>
<servlet-mapping>

</servlet-mapping>
</web-app>
I am getting an error Occurred at line 10 column 22, which is where I have marked in my file as '**' (it isn't actually there in the file, I just put it on here). Here is (a part) of the stack trace I get:

I agree the error message is suboptimal, but I'm also sure you want one <param-name> and one <param-value> per <init-param>. :-)

You are using <param-name> twice. but other init attribute should be <param-value>.

Websphere 7 with JSF 2

I need to use JSF 2 for an application running under Websphere 7.0.0.13, I have followed this:
http://www.manorrock.com/online/wiki/app/page/edit.html
***It says:
Even though Websphere 7 does not formally support JSF 2.0 you can get it to work in a degraded mode. Follow the steps below to get it to work on your version of Websphere 7.
Upgrade to at least version 7.0.0.13
Ship the Mojarra JAR files in your WEB-INF/lib directory
Set the WAR classloader to PARENT_LAST
Set the EAR classloader to PARENT_LAST and APPLICATION
Note the degraded mode means you are NOT going to be able to use #Resource or any JPA annotations. If you think you need support for it contact your IBM representative.
Note it will process #PostConstruct and #PreDestroy.***
I did this, but I getting this error, in the log:

Thanks for you help.

For WebSphere 7, I've followed another article:
http://wasbehindtheglass.blogspot.co.uk/2011/11/myfaces-20-and-websphere-application.html
I've created shared library on WebSphere (name is not important, only content) with following jars:
manifest.jar
myfaces-api-2.0.7.jar
myfaces-impl-2.0.7.jar
commons-logging-1.1.1.jar
commons-digester-1.8.jar
commons-collections-3.2.jar
commons-codec-1.3.jar
commons-beanutils-1.8.3.jar
\IBM\SDP\runtimes\base_v7\optionalLibraries\IBM\JSFProviders\WebSphere-MyFaces20-annotation-provider.jar
You need to give absolute paths. WebSphere-MyFaces20-annotation-provider.jar should be in your WebSphere installation. manifest.jar is the jar containing only following META-INF/MANIFEST.MF:
Manifest-Version: 1.0
Extension-Name: org/apache/myfaces
Specification-Title: MyFaces 2.0.7 shared lib
Specification-Version: 1.0
Specification-Vendor: apache.org
Implementation-Version: 1.0
Final thing to be done is to modify your pom.xml to create the manifest entries referring the shared library:
<manifestEntries>
<Extension-List>myfaces</Extension-List>
<myfaces-Extension-Name>org/apache/myfaces</myfaces-Extension-Name>
<myfaces-Specification-Version>1.0</myfaces-Specification-Version>
</manifestEntries>
After the deploy, if both shared library and manifest are configured correctly, the binding is automatically created.

I'd guess you are not only providing the JSF classes, but a second instance / api as well.
Check if you have a servlet-api or something similar in your WEB-INF/lib folder.
As it cannot load the ServletContext you get the other follow-up errors. Probably even loading a simple jsp with no JSF in it fails.

I tried this, and it is working, just put here an alternative solution for future questions
this issue happen because we have add the servlet-api-2.5.jar in the project lib so when we remove it work .
so here the final Step to get this work
1- set the Parent last in the class loading policy for the application and module as well .
2- don't add the servlet-api-2.5 .jar to the porject lib
taked from here

C:\apache-tomcat-8.0.3\webapps\kumar-app\WEB-INF\lib\servlet-api-2.3.jar
C:\apache-tomcat-8.0.3\lib\servlet-api.jar
I had above jar file version mismatch , i deleted the jar from C:\apache-tomcat-8.0.3\webapps\kumar-app\WEB-INF\lib\servlet-api-2.3.jar and my application worked properly.

Tomcat 7: Invalid mapping (java.lang.IllegalArgumentException) [duplicate]

This question already has answers here:
java.lang.IllegalArgumentException: The servlets named [X] and [Y] are both mapped to the url-pattern [/url] which is not permitted
(7 answers)
Closed 7 years ago.
I am migrating an existing project from Tomcat 6 to 7. Upon startup I am encountering this logged error message:
Jul 02, 2013 2:38:39 PM org.apache.catalina.startup.ContextConfig parseWebXml
SEVERE: Parse error in application web.xml file at jndi:/localhost/padd/WEB-INF/web.xml

Here the WEB-INF/web.xml line 309fff:

EDIT:
<servlet-mapping>
<servlet-name>ArtefactServlet</servlet-name>

Here tomcat's web.xml:
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<!-- The mappings for the JSP servlet -->
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.jsp</url-pattern>
<url-pattern>*.jspx</url-pattern>
</servlet-mapping>
I tried to play around with the mapping, but couldn't make any progress. Hope you can help!

The error says :
The servlets named [ArtefactServlet] and [saveArtefactServlet] are
both mapped to the url-pattern [/saveRestoration] which is not
permitted
So tomcat doesn't know which servlet to be called when your url pattern is matched. Give different url patterns for these two servlets ArtefactServlet, saveArtefactServlet

java.lang.IllegalArgumentException: The servlets named...
I fetched this cause where I create new servlet in different package (name='syncro'). My servlet located in syncro.SynchronizeServlet
And when I add information about this servlet in deployment descriptor (web.xml) I catch error: IllegalArgumentException
Example of incorrect descriptor part:
<servlet>
<description></description>
<display-name>SynchronizeServlet</display-name>
<servlet-name>SynchronizeServlet</servlet-name>
<servlet-class>SynchronizeServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>SynchronizeServlet</servlet-name>
<url-pattern>/SynchronizeServlet</url-pattern>
<url-pattern>/SynServlet</url-pattern>
</servlet-mapping>
When I add correct path for servlet - error disappeared. Correct desc below:
<servlet>
<description></description>
<display-name>syncro.SynchronizeServlet</display-name>
<servlet-name>syncro.SynchronizeServlet</servlet-name>
<servlet-class>syncro.SynchronizeServlet</servlet-class>

<servlet-mapping>
<servlet-name>syncro.SynchronizeServlet</servlet-name>
<url-pattern>/SynchronizeServlet</url-pattern>
<url-pattern>/SynServlet</url-pattern>
</servlet-mapping>

Deploying Jersey-enabled servlet to Tomcat: Exceptions

Here is what I'm trying to do: we are switching over to using JAXB and Jersey for all our REST services and XML/JSON serialization needs.
So far, I have been able to get a simple test working where some beans are annotated, some test objects created and these are perfectly serialized to either XML or JSON and return to the client upon request. I mostly wrote this based on some of the examples around the Internet, where the an HTTPServer is created and started in the main method.
I am now trying to put this same example into a WAR file and deploy it to my local Tomcat server so I can test it in a more production-like environment. Seeing as I was not able to get it to work on Tomcat 5.5.27 following the instructions here I went ahead and upgraded to Tomcat 6.0. Same instructions, same outcome, a huge InvocationTargetException.
What exactly am I missing guys?

You have probably a conflict somewhere, check your jar files and see if there are no duplicate classes. Use Tattletale to locate the problem
