[jboss-user] [JBoss Seam] - Remoting: Exception during loadResourceProviders
Hi!
I got my information from here
http://docs.jboss.com/seam/2.0.0.CR2/reference/en/html/remoting.html
please tell me what I did wrong.
My setup is like this:
| app.ear
| ejb.jar
| com/acme/..
| META-INF
| components.xml
| ejb-jar.xml
| persistence.xml
| web.war
| <resources>
| WEB-INF
| lib/jboss-seam-remoting.jar
| web.xml
| jboss-seam-debug.jar
| jboss-seam.jar
|
my components.xml:
| <?xml version="1.0" encoding="UTF-8"?>
| <components xmlns="http://jboss.com/products/seam/components"
| xmlns:core="http://jboss.com/products/seam/core"
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
| xsi:schemaLocation=
| "http://jboss.com/products/seam/core
http://jboss.com/products/seam/core-2.0.xsd
| http://jboss.com/products/seam/components
http://jboss.com/products/seam/components-2.0.xsd">
|
| <core:init jndi-pattern="myapp/#{ejbName}/local"/>
|
|
| </components>
|
|
my web.xml:
| <?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">
|
| <servlet>
| <servlet-name>Seam Resource Servlet</servlet-name>
|
<servlet-class>org.jboss.seam.servlet.SeamResourceServlet</servlet-class>
| </servlet>
|
| <servlet-mapping>
| <servlet-name>Seam Resource Servlet</servlet-name>
| <url-pattern>/seam/resource/*</url-pattern>
| </servlet-mapping>
|
| </web-app>
|
Now the problem is when accessing resources via seam/resource/*
I get the follwing exception
| 12:01:53,919 ERROR [[Seam Resource Servlet]] Allocate exception for servlet Seam
Resource Servlet
| java.lang.NullPointerException

I debugged the problem and here the NPE occurs:
| protected void loadResourceProviders()
| {
| Context tempApplicationContext = new ApplicationContext( new
ServletApplicationMap(context) );
|
| Init init = (Init) tempApplicationContext.get(Init.class);
| /**
| * Here init == null !!
| */
| for (String name : init.getResourceProviders())
| {
| AbstractResource provider = (AbstractResource)
tempApplicationContext.get(name);
| if (provider != null)
| {
| provider.setServletContext(context);
| providers.put( provider.getResourcePath(), provider );
| }
| }
| }
|
Thank you,
Thomas
