Exception in thread "main" java.lang.IllegalStateException: No EJB receiver available for handling -- jboss-as-7.1.1.Final
I'm writing a simple ejb application. Deployment succeeds, but when I try to access the method define in the interface the following exception is thrown:
org.jboss.ejb.client.EJBClient <clinit>
INFO: JBoss EJB Client version 1.0.5.Final

The bean is as follows:
package com.ibytecode.businesslogic;
import com.ibytecode.business.HelloWorld;
import javax.ejb.Stateful;
@Stateful
public class HelloWorldBean implements HelloWorld {
public HelloWorldBean() {
}
public String sayHello() {

}
}
The interface:
package com.ibytecode.business;
import javax.ejb.Remote;
@Remote
public interface HelloWorld {

}
I also have a class that establishes the server context and is used by the client for rmi

// This should fix JNDI issues
properties.put("jboss.naming.client.ejb.context", true);
initialContext = new InitialContext(properties);
}
return initialContext;

}
The client that accesses the bean is:

Solution
I've figured it out. There was an issue with the jboss-ejb-client.properties file. In jboss as 7 security credentials are enabled by default and, therefore, must be specified in the .properties file. The new file is as follows:
jboss-ejb-client.properties:
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host=localhost
remote.connection.default.port = 4447
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
remote.connection.default.username=myUser
remote.connection.default.password=myPass
To add a new user execute:
%JBOSS_HOME%\bin\add-user.bat (Win)
$JBOSS_HOME/add-user.sh (*nix)
where JBOSS_HOME is the directory in which jboss was extracted(assuming that a binary version is being used). This file must also be placed in the class path of the current project:
Note that placing jboss-ejb-client.properties in the project root directory may lead to deployment failure.
In order to successfully deploy applications in jboss7 it is also required that a (marker) file with a .dodeploy extension is created in
%JBOSS_HOME%\standalone\deployments\
The marker file must have the following naming structure:
ProjectName.jar.dodeploy
In my case it is:
HelloWorldSessionBean.jar.dodeploy
Note that a directory named ProjectName.jar(in my case HelloWorldSessionBean.jar) must also be present in:
%JBOSS_HOME%\standalone\deployments\
This directory contains the class files related to the bean(s) and the client.
The types of marker files, as well as sample workflows are illustrated bellow:
The marker files always have the same name as the deployment content to which
they relate, but with an additional file suffix appended. For example, the
marker file to indicate the example.war file should be deployed is named
example.war.dodeploy. Different marker file suffixes have different meanings.
The relevant marker file types are:
.dodeploy -- Placed by the user to indicate that the given content should
be deployed into the runtime (or redeployed if already
deployed in the runtime.)
.skipdeploy -- Disables auto-deploy of the content for as long as the file
is present. Most useful for allowing updates to exploded
content without having the scanner initiate redeploy in the
middle of the update. Can be used with zipped content as
well, although the scanner will detect in-progress changes
to zipped content and wait until changes are complete.
.isdeploying -- Placed by the deployment scanner service to indicate that it
has noticed a .dodeploy file or new or updated auto-deploy
mode content and is in the process of deploying the content.
This marker file will be deleted when the deployment process
completes.
.deployed -- Placed by the deployment scanner service to indicate that the
given content has been deployed into the runtime. If an end
user deletes this file, the content will be undeployed.
.failed -- Placed by the deployment scanner service to indicate that the
given content failed to deploy into the runtime. The content
of the file will include some information about the cause of
the failure. Note that with auto-deploy mode, removing this
file will make the deployment eligible for deployment again.
.isundeploying -- Placed by the deployment scanner service to indicate that it
has noticed a .deployed file has been deleted and the
content is being undeployed. This marker file will be deleted
when the undeployment process completes.
.undeployed -- Placed by the deployment scanner service to indicate that the
given content has been undeployed from the runtime. If an end
user deletes this file, it has no impact.
.pending -- Placed by the deployment scanner service to indicate that it
has noticed the need to deploy content but has not yet
instructed the server to deploy it. This file is created if
the scanner detects that some auto-deploy content is still in
the process of being copied or if there is some problem that
prevents auto-deployment. The scanner will not instruct the
server to deploy or undeploy any content (not just the
directly affected content) as long as this condition holds.
Basic workflows:
All examples assume variable $AS points to the root of the JBoss AS distribution.
Windows users: the examples below use Unix shell commands; see the "Windows
Notes" below.
A) Add new zipped content and deploy it:
1. cp target/example.war $AS/standalone/deployments
2. (Manual mode only) touch $AS/standalone/deployments/example.war.dodeploy
B) Add new unzipped content and deploy it:
1. cp -r target/example.war/ $AS/standalone/deployments
2. (Manual mode only) touch $AS/standalone/deployments/example.war.dodeploy
C) Undeploy currently deployed content:
1. rm $AS/standalone/deployments/example.war.deployed
D) Auto-deploy mode only: Undeploy currently deployed content:
1. rm $AS/standalone/deployments/example.war
Note that this approach is not recommended with unzipped content as the server
maintains no other copy of unzipped content and deleting it without first
triggering an undeploy temporarily results in a live application with
potentially critical resources no longer available. For unzipped content use
the 'rm $AS/standalone/deployments/example.war.deployed' approach.
E) Replace currently deployed zipped content with a new version and deploy it:
1. cp target/example.war/ $AS/standalone/deployments
2. (Manual mode only) touch $AS/standalone/deployments/example.war.dodeploy
F) Manual mode only: Replace currently deployed unzipped content with a new
version and deploy it:
1. rm $AS/standalone/deployments/example.war.deployed
2. wait for $AS/standalone/deployments/example.war.undeployed file to appear
3. cp -r target/example.war/ $AS/standalone/deployments
4. touch $AS/standalone/deployments/example.war.dodeploy
G) Auto-deploy mode only: Replace currently deployed unzipped content with a
new version and deploy it:
1. touch $AS/standalone/deployments/example.war.skipdeploy
2. cp -r target/example.war/ $AS/standalone/deployments
3. rm $AS/standalone/deployments/example.war.skipdeploy
H) Manual mode only: Live replace portions of currently deployed unzipped
content without redeploying:
1. cp -r target/example.war/foo.html $AS/standalone/deployments/example.war
I) Auto-deploy mode only: Live replace portions of currently deployed unzipped
content without redeploying:
1. touch $AS/standalone/deployments/example.war.skipdeploy
2. cp -r target/example.war/foo.html $AS/standalone/deployments/example.war
J) Manual or auto-deploy mode: Redeploy currently deployed content (i.e. bounce
it with no content change):
1. touch $AS/standalone/deployments/example.war.dodeploy
K) Auto-deploy mode only: Redeploy currently deployed content (i.e. bounce
it with no content change):
1. touch $AS/standalone/deployments/example.war
Windows Notes:
The above examples use Unix shell commands. Windows equivalents are:
cp src dest --> xcopy /y src dest
cp -r src dest --> xcopy /e /s /y src dest
rm afile --> del afile
touch afile --> echo>> afile
Note that the behavior of 'touch' and 'echo' are different but the
differences are not relevant to the usages in the examples above.
