And finally the context.xml in the conf folder:

But when I try to execute the application from Tomcat Manager, it fails to deploy. Here is the error in the Catalina log file:

Is there anything wrong with the context.xml file?
EDIT: I've changed the path to java:/comp/env/jdbc/xe but I get another error:

I think you are missing an env when you are retrieving your DataSource. Try:
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("java:comp/env/jdbc/xe");

I am trying to connect my java servlet program in local in eclipse IDE to my remote SQL database which is created in a web hosting.
AdminLoginServlet-

con=DriverManager.getConnection(url,username, password);
}
catch(ClassNotFoundException e)

I am not sure how to proceed or debug the piece of code.Thanks in advance for any pointer that anyone can provide.
Edit:(26 th feb,2017)
I found the connector for java to mysql was missing from the following link:
http://www.ccs.neu.edu/home/kathleen/classes/cs3200/JDBCtutorial.pdf
But I am not able to add it into build path as an external archive.I am getting following option-
Check the folder structure
Thanks in advance for any pointer that anyone can provide.
The database which you are connecting might not have values and also check the column names or you might have given the wrong name or you might not have included the respective jar file under WebContent folder.Take a keen look at all these.
I created a simple mvn webapp in netbeans and got it to work with h2. But I'm unable to get it to work with mysql as a datasource.
I've deployed the mysql 5.1.38 connector to Wildfly and it deploys and connects fine. I've added mysql to my persistence.xml as shown below. But it won't connect. I can connect to mysql in wildfly, mysql client, and within the services tab in wildfly.
After a lot of effort and research, I'm kind of lost.

Thanks to stackoverflow and jens
I used spring 3.2.2 and jackson 1.9.10
Now this issue is resolved
I got this error when I deleted the bean that the "ref" property below was pointing to (my bean's id was 'dateObjectMapper').
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="objectMapper" ref="dateObjectMapper" />
</bean>
If your spring is 4.0 then you use org.springframework.http.converter.json.MappingJackson2HttpMessageConverter
3.0 use
org.springframework.http.converter.json.MappingJacksonHttpMessageConverter

import edu.drg.interfaces.ILRSManager;
#Local
public interface LRSManager extends ILRSManager {
}
I'm trying to access the getAllPersons() method via the Interface manager in a servlet as followss:
#WebServlet("/RetrieveAllPersons")
public class RetrieveAllPersons extends HttpServlet {
private static final long serialVersionUID = 1L;
//private ILRSManager manager = LRSManagerFactory.getInstance().getLRSManager();
#EJB
private LRSManager manager;
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Log logger = LogFactory.getLog(this.getClass());
logger.debug("Entering servlet");
List<IPerson> allPersons = manager.getAllPersons();
request.setAttribute("allPersons", allPersons);
logger.debug("Retrieved from persons: "+allPersons);
RequestDispatcher rd = request.getRequestDispatcher("persons.jsp");
rd.forward(request, response);
}
}
However, i have no idea why i'm getting the following exception:

It seems something is wrong with TransactionManager, i'm wondering if i still have to map my entities via hibernate.cfg.xml and add this mapping as the reference to persistence.xml. Also i have noticed what when i'm trying to access my method, the entitymanager removes all my records from the table.
I still didn't find anything that could help me on tomee documentation. Any ideas?
Found the solution, may be it could be usefull to someone.
As we are going to use Hibernate Persistence Provider and JTA, the transaction manager also should be the corresponding one, till now i was trying to use implicit, the open ejb transaction manager.
To solove this problem, we should use in persistence.xml, instead of
<property name="hibernate.transaction.manager_lookup_class"
value="org.apache.openejb.hibernate.TransactionManagerLookup"/>
this:
<property
name="transaction.factory_class" value="org.hibernate.transaction.JTATransactionFactory"/>
Also be aware of hibernate version you are using, i'm using 4.x, the provider
<provider>org.hibernate.ejb.HibernatePersistence</provider>
is deprecate, use this instead:
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
I have issue with primefaces 5.0 component p:fileDownload , I have following bean store DefaultStreamedContent , and I get the value stored to download it simply :
Bean :
public class EBMail implements Serializable {
private DefaultStreamedContent attachment;
// # here setter and getter too .
}
and from XHTML file :
<p:commandLink ajax="false" value="Download Attachment" rendered="#{mbMail.attachment != null}">
<p:fileDownload value="#{mbMail.attachment}" />
</p:commandLink>
I get mail attachment file for first time, in 2nd time I get the following exception :

I'm running on JFS 2.2.7 , Primefaces 5.0 , I upload file into bean my issue when I download it for 2nd time, even for another object 'mail' .
Any solution, I looked after many solutions around nothing helped me or I've already tested it.
I solved issue finally, I make new class store my data, and action that prepare stream to download from my class object, and when download file I read bytes from my class bytes, like the following:
Class:
public class Attachment implements Serializable {
private String name;
private String type;
private String encoding;
private byte[] data;
// ... Setters and getters ...
public Attachment () {
this.encoding = "UTF-8";
}
}
Bean:
public class MailBean implements Serializable {
// alot of properties
private Attachment attachment;
// setters and getters
}
Managed Bean :
public class MailManagedBean implements Serializable {
private DefaultStreamedContent attachmentToDownload;
private MailBean mail;
// # here setter and getter too .
public void prepare() {
InputStream stream = new ByteArrayInputStream(mail.getAttachment.getData());
attachmentToDownload = new DefaultStreamedContent(stream, mail.getAttachment.getType(), mail.getAttachment.getName(), mail.getAttachment.getEncoding());
}
}
In XHTML file (I added action) :
<p:commandLink ajax="false" value="Download Attachment"
rendered="#{mbMail.mail.attachment != null}" action="#{mbMail.prepare()}">
<p:fileDownload value="#{mbMail.attachmentToDownload}" />
</p:commandLink>
public StreamedContent getExportFile() {
Field field = exportFile.getStream().getClass().getDeclaredField("path");
field.setAccessible(true);
String path = (String)field.get(exportFile.getStream());
InputStream tempStream = new FileInputStream(path);
exportFile = new DefaultStreamedContent(tempStream,exportFile.getContentType(), exportFile.getName());
return exportFile;
}
