Failed to load ApplicationContext caused by ArrayIndexOutOfBoundsException in ClassReader
(5 answers)
Closed 5 years ago.
Hi guys i've been having trouble with one of my controllers, when I go to call it it throws an ArrayIndexOutOfBoundsException and I have no idea why. I've tried changing the configuration of web.xml and everything over and over and am getting nowhere. I get the following exception when attempting to call /categories:
SEVERE: StandardWrapper.Throwable
java.lang.ArrayIndexOutOfBoundsException: 3145

Your problem happens here:
#RequestMapping(value = "/categories", method = RequestMethod.GET, headers = "content-type=application/json")
#ResponseBody
public String getCategoryList() {
StringBuilder sb = new StringBuilder();
for (String s : finderCache.getCategory()) {
sb.append(s + "\n");
}
return sb.toString();
}
The problem happens in your finderCache.getCategory(). where your getCategory has no items in it.
Please check with a debugger what finderCache.getCategory() has
If this isnt the problem, please post the logcat of your error.

You will need to ensure that the RegisterServlet class is actually available to the servlet container.
Typically, inside the WEB-INF directory, you will have the following directories:
lib
classes
You will need to make sure that the class is available inside the classes directory or the class is inside a JAR in the lib directory

java.lang.IllegalStateException In clustered environment

I have web application with spring, spring security, spring session with hazelcast.
It is running on clustered environment.
I see this exception in logs from time to time but can't reproduce it in locally.
It looks like some itercetptor or filter does not work correctly.
Any suggestion how to find the cause of the problem?

spring com.sun.jersey.api.container.ContainerException: The ResourceConfig instance does not contain any root resource classes

I've just started my first simple spring program. I'm trying to make a Rest API using Jersey framework with spring. Its a very basic simple program to fetch list of countries. But, however it throws the error. I've gone through other solutions, none of them worked.

What is missing in this one?

You don't have your Jersey servlet (ServletContainer) configured in your web.xml to pick up any resource classes. So Jersey starts up with no resources registered.
With web.xml generally the way to go, is to set an init-param to tell Jersey to scan a certain package for classes annotated with #Path and #Provider. To do that, just add the following
<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>the.package.you.want.to.scan</param-value>
</init-param>
...
</servlet>

REST WS with Interface

I'm trying to implement a REST WS. The following code works ok:
#Path("/MyRest")
#WebService
public class MyService {
#GET
#Produces(MediaType.APPLICATION_JSON)
#Path("/{id}")
public Response test(#PathParam("id") String id) {
String str = "{\"status\":\"ok\",\"id\":\"" + id + "\"}";
return Response.status(200).entity(str).build();
}
}
web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>WSRest</display-name>
<servlet>
<servlet-name>Jersey REST Service</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>test</param-value>
</init-param>

</servlet>
<servlet-mapping>
<servlet-name>Jersey REST Service</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>
Now i'm trying to do it with an Interface. The interface would be like follows, I guess:
#Path("/MyRest")
#WebService
public interface IService {
#GET
#Produces(MediaType.APPLICATION_JSON)
#Path("/{id}")
public Response test(#PathParam("id") String id);
}
And now the WS implementation would be like this, right?:
public class MyService implements IService{
#Override
public Response test(#PathParam("id") String id) {
String str = "{\"status\":\"ok\",\"id\":\"" + id + "\"}";
return Response.status(200).entity(str).build();
}
}
I'm getting "HTTP Status 500 - Servlet.init() for servlet Jersey REST Service threw exception" when I try to "run" it again :/
Any ideas? Thanks in advance.

Thank you for your help

With JSF you must not used servlets. You use managed beans.
In order to fix the above code, you should provide an action method, and invoke that method from your command button. In order to get more into the spirit of JSF, I'd suggest starting with a tutorial and/or a sample JSF probject.
