Errors$ErrorMessagesException when using Jersey in Java
Solution 1
Your question seems to be a duplicate and has probably been appropriately addressed. I too had the same issue some time ago. Click here to see the accepted answer that resolved it for me
And in case you're reluctant to follow the link, first of all, try adding jersey-multipart.jar
and mimepull.jar
to your project libraries... And if your project is a Maven project, add the following dependencies to your pom.xml
. The mimepull
dependency should ship along with it.
<dependency>
<groupId>com.sun.jersey.contribs</groupId>
<artifactId>jersey-multipart</artifactId>
<version>1.8</version>
</dependency>
Remember to ensure that the version of jersey-multipart
that you use, is the same as the version of jersey
that you're using in the project.
Just in case the above solution doesn't resolve your issue, you may want to see here for more useful tips too. Cheers!

Check for clashing @Path annotations. This will result with the same error. It's a weird error for communicating path issues, but you can easily test it by renaming the matching paths.
Example of cashing paths in the code below
Some class
@Path("/storage")
public class BookingRestService {
@GET
@Path("/bookings")
@Produces(value = MediaType.APPLICATION_XML)
and another class
@Path("/storage")
public class StorageRestService {
By renaming any of the @Path("/storage")
the problem seizes to impair your work progress.

I am using Jersy to develeop REST webservices, this is my simple code:
@GET @Path("/retrieveCustomerInformation/{jsonString}") @Produces(MediaType.APPLICATION_JSON) public String retrieveCustomerInformation(@PathParam("jsonString")JSONObject jsonObject) throws Exception { //Other codes here }
But when I ping the rest service url from browser, I am getting below exception:
javax.servlet.ServletException: Servlet.init() for servlet jersey-serlvet threw exception org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:502) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:100) org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:953)
and the root cause is:
com.sun.jersey.spi.inject.Errors$ErrorMessagesException com.sun.jersey.spi.inject.Errors.processErrorMessages(Errors.java:170) com.sun.jersey.spi.inject.Errors.postProcess(Errors.java:136) com.sun.jersey.spi.inject.Errors.processWithErrors(Errors.java:199)
Can someone guide me, what causes this error? I am finding difficult to understand this error message as it doesn't provide any useful information to debug.
This is my web.xml
<servlet> <servlet-name>jersey-serlvet</servlet-name> <servlet-class> com.sun.jersey.spi.container.servlet.ServletContainer </servlet-class> <init-param> <param-name>com.sun.jersey.config.property.packages</param-name> <param-value>com.test/param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>jersey-serlvet</servlet-name> <url-pattern>/rest/*</url-pattern> </servlet-mapping>
I am using Jersey 1.8, JDK 1.7 and App is running on Tomcat 7.0. If required I can provide more information.
