previously my project was on jdk 6 with jboss 4.i upgraded from jdk6 to jdk8 . When i was using jdk 8 with jboss4 it was working properly but after upgrading jboss 4 with wildfly 15 i am getting below error.
in web.xml i configured crystalReportViewer as given below .wildfly 15 is giving error but when i removed the crystalReportConfiguration line then its working properly..

RESTful API - Getting HTTP 500 error all the time

I am making a simple RESTful API to my application. I've made another package in my project (other from one where is my main java class, servlet, and model). And then I've made my resource file, very simple which looks like this:
package com.java.api;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;
#Path("webservice")
public class ZipcodeService {
#GET
#Path("/lookup")
public Response lookup() {
return Response.ok().entity("Los Angeles").build();
}
}
and this is my web.xml:

I am not using Maven. I am using Netbeans IDE and Tomcat server. I uploaded Jersey 2.25 all jar files to WEB-INF/lib folder. I am experimenting with web.xml to fix it but I have no more ideas. Here is the structure of my project:

Perhaps you have problems with your libraries.
root cause
java.lang.NoSuchMethodError: org.glassfish.jersey.CommonProperties.getValue(..
by the server initialisation shows that you forgot to add some library (perhaps it's not in your Jersey 2.25, check for it). Your can also try to use another version of Jersey.

You need to look in (and post) your Tomcat logs. Look at catalina.out. It looks to me like your web.xml doesn't have a closing web-app tag, but that might just be because you didn't post the full web.xml.
Also, you need to package your application as a WAR file. Tomcat expects your web application WAR file to be located under the webapps directory.
edit:
the method wasn't found, therefore the appropriate JAR isn't actually on the classpath (lib folder).

There was the a problem with the EAR being created. I deleted the application, restarted the server and redeployed the application which solved it.

You need to add jar with Struts to your application. Build path is good in your development environment, but to run it must be somehow in the classpath during runtime. The easiest is as Steve C suggested - to add struts.jar to your WEB-INF/lib.

This kind of java.lang.ClassNotFoundException can manifest sometimes when a dependent class is not available.
Make sure that you application has access to the dependent jars as well, such as:
commons-beanutils
commons-digester
commons-logging
etc

By default JBoss 5.0 contains JSF library at location - jboss-5.0.0.GA\server\default\deploy\jbossweb.sar\jsf-libs.
You have to provide explicitly for JSF 2.0 at this location, if implementation requires it.
jboss-faces.jar
jsf-api.jar
jsf-impl.jar
Also, you have to provide required JSF implementation specific jars during project deployment. Below is the \WEB-INF\lib content.
cssparser-0.9.5.jar
guava-13.0.1.jar
richfaces-components-api-4.3.2.Final.jar
richfaces-components-ui-4.3.2.CR1.jar
richfaces-core-api-4.3.2.Final.jar

Jersey + App Engine project launch error

Did a lot of search, but no luck.
I'm trying to make a 'hello world' app which integrates Jersey and Google App Engine.
In Eclipse, I created a 'Web Application Project' and added Jersey JAR to the build path.
Then I modified web.xml and it looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

In the package 'com.example.myJersey' I have HelloWorldResource.java, here is an excerpt:
// The Java class will be hosted at the URI path "/helloworld"
#Path("/helloworld")
public class HelloWorldResource {
// The Java method will process HTTP GET requests
#GET
// The Java method will produce content identified by the MIME Media
// type "text/plain"
#Produces("text/plain")
public String getClichedMessage() {
// Return some cliched textual content
return "Hello World";
}
}
When I click run, I get this error:

EDIT:
Maybe there is a misconfiguration in web.xml. Looks like Jetty doesn't like Jersey's servlet class.
I would appreciate any kind of help.

I recently put together a project template on GitHub combining Jersey and Guice for AppEngine. It may help to compare with a running app.

Jersey requires Java 1.6. Is this what the Google App Engine runs on? Maybe your Google App instance is configured to run on an earlier Java version.

Look at this:
http://code.google.com/p/googleappengine/wiki/WillItPlayInJava
Make sure that you run Jersey 1.5 and configure as required in the doc. Also, are you using other libraries? Those may create a classloading conflict?
