id to load is required for loading
id to load is required for loading is a common error you may face while runtime .
I have faced this error while a bean call . A session bean of type entity is interacting with JPA project This can come due to several reasons based on your project .Some of them are as below:
If you invoke find method by passing null as primary key hibernate will throw the following exception to you .
If it is not set you might face the following exception .

org.hibernate.MappingException: Unknown entity:
Hi Guys ,
org.hibernate.MappingException: Unknown entity: is a common error you may face while runtime .
I have faced this error while a bean call . A session bean of type entity . This can come due to several reasons based on your project .Some of them are as below:
1.In your persistence.xml you need to dd that particular class like as below :
<class>model.Account</class>
If it is not set you might face the following exception .

'hibernate.dialect' not set
Hi Guys ,
'hibernate.dialect' not set is a common error you may face while deploying your EAR . This can come due to several reasons based on your project .
Check the below stack trace ..
To find the root cause you need to check the following :
1. make sure your bean's persistance.xml is having the following entry :
<persistence-unit name="your unit name" transaction-type="JTA">
2. make sure your jpa project's is having the same entry .
<persistence-unit name="your unit name" transaction-type="JTA">
3. make sure your bean is using the same unit name .
@PersistenceContext(unitName = "ConsultingJPA")
If it is not set you might face the following exception .
Caused by: org.hibernate.HibernateException: Connection cannot be null when 'hibernate.dialect' not set

Fed up....
Now remove the entry and create initail context with any hashtable .
You might possible get the following error
03:58:25,999 ERROR [stderr] (http-localhost/127.0.0.1:8088-1) javax.naming.NameNotFoundException: consultingDS -- service jboss.naming.context.java.consultingDS

Then you have to make sure that your standalone.xml and domain.xmlis updated with the datasource and driver
If you have updated domain.xml and still the same exception as above the you have to update standalone.xml
while starting server might throw the following exception :
04:04:41,444 INFO [org.jboss.as.controller] (Controller Boot Thread) JBAS014774: Service status report
JBAS014775: New missing/unsatisfied dependencies:

JBOSS AS 7 JMS
Hi Guys ,
I am going to set up Jboss AS 7 using Eclipse Kepler .
First of all you need to downlaod Jboss Developer Studios for Eclipse Kepler .
You need to create a server and all that basic steps that everyone knows .
If you are using JBOSS AS 7 for the first time and if you are an overconfident JBOSS 5 user , then be prepared you might face some difficulties .
Eclipse , by default will set up Program argument for server as
-mp "D:/software/jboss-eap-6.2.0/jboss-eap-6.2/modules" -logmodule org.jboss.logmanager -jaxpmodule javax.xml.jaxp-provider org.jboss.as.standalone -b localhost -c standalone.xml
You need to change it to
-mp "D:/software/jboss-eap-6.2.0/jboss-eap-6.2/modules" -logmodule org.jboss.logmanager -jaxpmodule javax.xml.jaxp-provider org.jboss.as.standalone -b localhost -c standalone-full.xml
Remember you can start JBOSS using standalone.xml also but messaging will not be visible and hornetq server for messaging will not be started .
