I'm creating a log-in page and to check the login details I have connected with database using hibernate.I'm transporting data via servlets and I UserDAO dao = new UserDAO is my object here for DAO class
I got exception like this:

What should I do ?

Hibernate jar is missing, if using Maven then add the dependency else download Hibernate and use the proper jars which are required to work with Hibernate.

Spring - Dynamic properties in compilation time

I was developing in almost pure XML-based Spring and I want to switch to annotation-based. But I have problem with dynamic properties.
In XML-based, I defined properties like this :
<context:property-placeholder location="classpath:server-${coffee_feedback_env}.properties"/>
And when I want to compile it, I could just do this : mvn clean package -Dcoffee_feedback_env=dev
In this case, file named server-dev.properties was chosen.
However same approach with annotation-based does not work. When I define property file like this : #PropertySource(value = { "classpath:server-${coffee_feedback_env}.properties" }), it does end with error

Is there similar way to define different property files for different distributions as before?
How was pointed out, the eviroment variable should be passed to Tomcat, I added this line <Environment name="coffee_feedback_env" value="dev" type="java.lang.String" override="false"/> to tomcat/conf/context.xml and it works as expected.

IllegalArgumentException loading properties for listener in servlets 3.1 application

I have a ServletContextListener which is giving me an IllegalArgumentException when it tries to load the properties from the file. My code is as follows:
private final static Properties properties = new Properties();
#Override
public void contextInitialized(ServletContextEvent sce) {
ServletContext sc = sce.getServletContext();
try {
// Load MyProject's properties file.
properties.load(sc.getResourceAsStream(sc.getInitParameter("myProjectPropsFilePath")));
}
catch(IOException e) {
Utils.printStackTrace(e);
}
// Write properties to ServletContext.
sc.setAttribute("properties", properties);
}
The context parameter is being retrieved from web.xml but I do not understand why the IllegalArgumentException is being thrown at line:
properties.load(sc.getResourceAsStream(sc.getInitParameter("myProjectPropsFilePath")));
The stacktrace is as follows:

Any ideas? I am using Apache Tomcat 8.0.3.
The appropriate part of web.xml is:
<!-- Listeners and parameters. -->
<listener>
<description>SetPropertiesServletContextListener</description>
<listener-class>myProject.listener.SetPropertiesServletContextListener</listener-class>
</listener>
<context-param>
<param-name>myProjectPropsFilePath</param-name>
<param-value>\WEB-INF\properties\myProject.properties</param-value>
</context-param>

The path should contain / as a separator because /WEB-INF/ remains the same in windows and in linux. You probably have wrong values in web.xml. According to Java API specs, you always use /.
This is wrong: <param-value>\WEB-INF\properties\myProject.properties</param-value>
Should've been:
<param-value>/WEB-INF/properties/myProject.properties</param-value>

.Jar file in .war file does not get database connection tomcat java

I have a Webservice which passes a string to a method of a jarfile. In the method are some database operations.
I created a .war file and wanted to run it in tomcat 8. But no changes are made in the database.
I googled a lot about tomcat database connections, but it looks like to me, that every tutorial is for webservice which directly use the database.
I somehow think that the jarfile should make the database connections without changes in the tomcat config or the code. in the cmd my jar is working fine.
What Informations do you need to know? I was not shure if anycode will be helpful. If you need something just tell me.
Edit:
I added the Tomcat to the eclipse environment. I created an easy webservice to test if tomcat is the problem. The answer was, that the other webservice were running in eclipse.
I created a dynamic web project added the main project as external jarfile.
I wrote the java class
import javax.jws.WebMethod;
import de.morpheus.chatbot.brain.io.datasource.DataSourceDB;
import de.morpheus.chatbot.model.*;
public class WSTEST {
private BotInit chatbot = new BotInit(new DataSourceDB());
#WebMethod
public String communicate(String input) {
return this.chatbot.processInput(input);
}
I right-clicked on the wetest.java in the project explorer and created the webservice.
type:Bottom UP
*StartService
*TestClient
*Monitoring the webservice
Then I clicked finish.
The Web Services Test Client window opened, and all MEthods worked except communication.
Here is the error

java.util.ServiceConfigurationError: javax.xml.parsers.SAXParserFactory: Provider org.apache.xerces.jaxp.SAXParserFactoryImpl not found?

Any body ever had this error before: I made some minor changes to ensure that the connections in my DB connection pool was being released, ran it and tried to login and this error was thrown. I am assuming that this is something on the server side seeing as how the first line is a direct reference to Catalina but I am not really sure where to start looking.

The issue is that my pom.xml file presented a dependency that was in conflict with a couple of .jar files that I had added to my library. The main one was the mysql connector jar, I had reinstalled tomcat on my computer at work and as a quick work around instead of including the jar in my tomcat library I just added it to my pom.xml as a dependency causing a conflict with my tomcat and IDE setup on my home computer.
After removing this dependency from the pom.xml and my jstl dependency from my pom.xml everything worked like a dream. Being as my program had the .jar files included they were just bumping heads.
