[CDI] Handling NonexistentConversationException Gracefully (my way)

On January 6, 2012, in CDI, Java EE 6, JBoss, JBoss AS 7, JBoss AS 7.0.2.Final, Seam 3, Solder, by lucasterdev

In this post I’ll be using:

  • JBoss AS 7.0.2.Final
  • Seam Solder 3.1.0.Final

Here’s my adventure in dealing with NonexistentConversationException…

Round 1

If you request a page with a non existent conversation id, a javax.enterprise.context.NonexistentConversationException will be thrown.

For example, if you type something like: http://localhost:8080/myapp/somePageWithAConversationScopedBean.jsf?cid=someNonExistentCid

You’ll see this page:

HTTP Status 500 -

type Exception report

Joshua Davis suggests a workaround that *should* solve the problem: http://shrubbery.mynetgear.net/c/display/W/Handling+NonexistentConversationException+Gracefully

The forum thread is: http://seamframework.org/Community/HandlingNonexistentConversationExceptionWithSeam3

Add this property to your pom.xml…

<properties>
    <seam.solder.version>3.1.0.Final</seam.solder.version>
</properties>

…add these dependencies to your pom.xml:

<dependency>
    <groupId>org.jboss.solder</groupId>
    <artifactId>solder-api</artifactId>
    <version>${seam.solder.version}</version>
    <scope>compile</scope>
</dependency>
<dependency>
    <groupId>org.jboss.solder</groupId>
    <artifactId>solder-impl</artifactId>
    <version>${seam.solder.version}</version>
    <scope>runtime</scope>
</dependency>

…and create this class:

package solder;

import javax.enterprise.context.NonexistentConversationException;
import javax.inject.Inject;
import org.jboss.solder.exception.control.CaughtException;
import org.jboss.solder.exception.control.Handles;
import org.jboss.solder.exception.control.HandlesExceptions;
import org.jboss.solder.logging.Logger;

@HandlesExceptions
public class MyHandlers {

	@Inject private Logger log;

	public void onNonexistentConversation(@Handles CaughtException evt) {
		log.error("NonexistentConversationException! " + evt.getException().getMessage(), evt.getException());
		evt.handled();
	}
}

You get this page:

HTTP Status 500 -

description The server encountered an internal error () that prevented it from fulfilling this request.
JBoss Web/7.0.1.Final

and this output:

This happens because of a known Weld bug: https://issues.jboss.org/browse/WELD-855

Joshua Davis’ workaround consists of telling Weld to create a new Transient conversation.

Modify our solder.MyHandlers.java:

package solder;

import javax.enterprise.context.NonexistentConversationException;
import javax.inject.Inject;

import org.jboss.solder.exception.control.CaughtException;
import org.jboss.solder.exception.control.Handles;
import org.jboss.solder.exception.control.HandlesExceptions;
import org.jboss.solder.logging.Logger;
import org.jboss.weld.context.http.HttpConversationContext;

@HandlesExceptions
public class MyHandlers {

	@Inject private Logger log;

	public void onNonexistentConversation(@Handles CaughtException evt, HttpConversationContext conversationContext) {
		log.error("NonexistentConversationException! " + evt.getException().getMessage(), evt.getException());
		evt.handled();
		conversationContext.activate(null); // Workaround WELD-855 - Create a new transient conversation.
	}
}

So far, this is the solution suggested in the wiki…
Guess what? It. does. not. work. (You still get HTTP Error 500.):-/

At least, it does not work with JBoss AS 7.0.2.Final and Seam Solder 3.1.0.Final, which are the version I’m using. Joshua didn’t mention which version he tested his workaround against, by the way. When you write an article, you have to ALWAYS mention the versions!!!

My workaround is the following:

package solder;

import java.io.IOException;

import javax.enterprise.context.NonexistentConversationException;
import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
import javax.inject.Inject;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.jboss.solder.exception.control.CaughtException;
import org.jboss.solder.exception.control.Handles;
import org.jboss.solder.exception.control.HandlesExceptions;
import org.jboss.solder.logging.Logger;
import org.jboss.weld.context.http.HttpConversationContext;

@HandlesExceptions
public class MyHandlers {

	@Inject private Logger log;

	public void onNonexistentConversation(@Handles CaughtException evt, HttpServletRequest request, HttpServletResponse response) {
		log.error("NonexistentConversationException! " + evt.getException().getMessage());
		evt.handled();
		// We redirect to the same page, but without cid. This will trigger a new JSF request lifecycle
		// and start a new transient conversation.
		// The drawback is: we cannot append messages to the view, because there is no active FacesContext.
		String redirectURL = response.encodeRedirectURL(request.getRequestURL().toString());
		try {
			response.sendRedirect(redirectURL);
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}

Round 2

Turns out Joshua Davis uses Seam Solder version 3.1.0.Beta2. So, I change my configuration.

My dependencies now are:

<properties>
	<seam.version>3.1.0.Beta2</seam.version>
	<weld.version>1.1.2.Final</weld.version>
</properties>

<dependencies>
	<dependency>
		<groupId>org.jboss.seam.solder</groupId>
		<artifactId>seam-solder</artifactId>
		<version>${seam.version}</version>
	</dependency>
	<dependency>
		<groupId>org.jboss.seam.catch</groupId>
		<artifactId>seam-catch</artifactId>
		<version>${seam.version}</version>
	</dependency>
	<dependency>
		<groupId>org.jboss.seam.faces</groupId>
		<artifactId>seam-faces</artifactId>
		<version>${seam.version}</version>
	</dependency>
	<!-- seam-faces depends on prettyfaces -->
	<dependency>
		<groupId>com.ocpsoft</groupId>
		<artifactId>prettyfaces-jsf2</artifactId>
		<version>3.3.2</version>
	</dependency>
	<dependency>
		<groupId>org.jboss.weld</groupId>
		<artifactId>weld-core</artifactId>
		<version>${weld.version}</version>
		<scope>compile</scope>
	</dependency>
		<dependency>
		<groupId>org.jboss.spec</groupId>
		<artifactId>jboss-javaee-6.0</artifactId>
		<version>1.0.0.Final</version>
		<type>pom</type>
		<scope>provided</scope>
	</dependency>
</dependencies>

seam-solder 3.1.0.Beta2 also needs the jboss-deployment-structure.xml file for logging to work:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
	<deployment>
		<dependencies>
			<module name="org.jboss.logmanager" />
		</dependencies>
	</deployment>
</jboss-deployment-structure>

By the way, @Inject Logger logger in a PhaseListener doesn’t work in seam-solder 3.1.0.Beta2

The exception handler is now as follows:

package solder;

import javax.enterprise.context.NonexistentConversationException;
import javax.inject.Inject;

import org.jboss.seam.exception.control.CaughtException;
import org.jboss.seam.exception.control.Handles;
import org.jboss.seam.exception.control.HandlesExceptions;
import org.jboss.seam.logging.Logger;

import org.jboss.weld.context.http.HttpConversationContext;

@HandlesExceptions
public class JoshuaHandlers {
	@Inject
	private Logger logger;

	public void onNonexistentConversation(
			@Handles CaughtException evt,	HttpConversationContext conversationContext) {
		java.awt.Toolkit.getDefaultToolkit().beep(); // I added a sound effect ;P
		logger.error("NonexistentConversationException!\n" + evt.getException().getMessage(), evt.getException());
		evt.handled();
	}
}

Now, if I enter a non existent cid, this is the page I get:

HTTP Status 500 -

Uhm… this might be what the wiki talks about.

Now, let’s try the workaround again. The exception handler is as follows:

package solder;

import javax.enterprise.context.NonexistentConversationException;
import javax.inject.Inject;

import org.jboss.seam.exception.control.CaughtException;
import org.jboss.seam.exception.control.Handles;
import org.jboss.seam.exception.control.HandlesExceptions;
import org.jboss.seam.logging.Logger;

import org.jboss.weld.context.http.HttpConversationContext;

@HandlesExceptions
public class JoshuaHandlers {
	@Inject
	private Logger logger;

	public void onNonexistentConversation(
			@Handles CaughtException evt,	HttpConversationContext conversationContext) {
		java.awt.Toolkit.getDefaultToolkit().beep(); // I added a sound effect ;P
		logger.error("NonexistentConversationException!\n" + evt.getException().getMessage(), evt.getException());
		evt.handled();
		conversationContext.activate(null); // Workaround WELD-855 - Create a new transient conversation.
	}
}

Yes! The view now renders

, and the console output is:

So, what changed? The main differences between my configuration and Joshua’s are:

  • Different Seam version (me 3.1.0.Final, him 3.1.0.Beta2)
  • Added seam-faces (and its transitive dependencies: seam-imternational, joda-time, prettyfaces-jsf2)

I thinks seam-faces plays a great role in all this. So, I’l try to revert my configuration back to how it was at the beginning, and I will add seam-faces.

[...later...]

Yes! seam-faces was the missing piece.

Here’s the working pom.xml:

Here’s the working exception handler:

package solder;

import javax.enterprise.context.NonexistentConversationException;
import javax.inject.Inject;

import org.jboss.solder.exception.control.CaughtException;
import org.jboss.solder.exception.control.Handles;
import org.jboss.solder.exception.control.HandlesExceptions;
import org.jboss.solder.logging.Logger;

import org.jboss.weld.context.http.HttpConversationContext;

@HandlesExceptions
public class JoshuaHandlers {

	@Inject
	private Logger logger;

	public void onNonexistentConversation(
			@Handles CaughtException<NonexistentConversationException> evt, HttpConversationContext conversationContext) {
		java.awt.Toolkit.getDefaultToolkit().beep();
		logger.error("NonexistentConversationException!\n" + evt.getException().getMessage(), evt.getException());
		evt.handled();
		conversationContext.activate(null); // Workaround WELD-855 - Create a new transient conversation.
	}
}

In the next posts I’ll show how to implement a Workspace Manager (a-la Seam 2).
