Java: Tomcat 7 Exception loading sessions from persistent storage: ClassNotFoundException

After the restart of my Tomcat 7 I am loosing all active sessions.
In the catalina.out file I can see the following:

de.mumscasino.core.User is a class of my ROOT.war which is used to control all user values in the application. After the startup my application is running without any problems. JSPs and Servlets are able to find this class and work with it. Sessions can be created and closed. After the shutdown of Tomcat I can see the SESSION.ser file created.
I have checked my code. Users implements java.io.Serializable, all fields of this class are boolean, String, int or implements java.io.Serializable also.
In my eclipse IDE with a local Tomcat7 I can restart it without loosing my session. I don't know what I can try to fix now.

java.lang.classnotfoundException: Logger

I have an error with occuring in my tomcat server and I have no idea on how can I solve it :
I think that there are some classes missing but I have not idea of what is missing,
here below the following output of the console , i am using eclipse and I run my app on apache tomcat 8.30

unable to start tomcat 8 in kepler eclipse adding resource tags in server.xml

I am getting the below exception when trying to start tomcat 8 from kepler eclipse after adding a project. I could run the same project in lomboz eclipse with tomcat 5.5.
I am still using the same jar files which I used previously in lomboz eclipse.
Can anyone please help me to fix this up.

I think this error can happen when your jar files has not been exported with your web archive,
you can follow below steps .
Right click the project -> Build Path -> Configure Build Path

I think you didn't include a library in your project.
Caused by: java.lang.NoClassDefFoundError: LConfiguration;
Caused by: java.lang.ClassNotFoundException: Configuration
You are missing jar file. Try to include in under WEB-INF/lib folder.

This issue caused by older version of java so try with java 1.7 or java 1.8
Also try
Check JAVA_HOME in system variable
Check Installed JRE in eclipse: window >> preferences >> Java >> Installed JRE and point the right jdk or jre
Check java tomcat server should match with Java version type(32bit or 64 bit)

What could be the error. I installed M2E and M2WTP in eclipse.

Have you checked if this is caused by the path in this case which contains spaces ? (Document base C:\Users\akhil nambiar\workspace.metadata.plugins\org.eclipse.wst.server.core\tmp3\wtpwebapps\CGSang does not exist or is not a readable directory)

I solved this myself.
Following are the commands to be typed in terminal/command prompt
mvn eclipse:clean
mvn eclipse:eclipse -Dwtpversion=2.0
Reopen in eclipse. Right click the project and choose import into maven project.

exception while deploying spring app on tomcat 6

I'm trying to make a simple web app using spring and deploying it on Tomcat 6. When I try to deploy it on the server, it gives me the following error. I'm unable to figure out if the problem is with Tomcat or my app.

Can anybody please help make sense of this exception?
Thanks,

I think the problem lies here:
Parse error in application web.xml file at jndi:/localhost/SpringPOC/WEB-INF/web.xml
And here:
Servlet mapping specifies an unknown servlet name profile
Seems like you want to map a server to a given path like for example:
<servlet-mapping>
<servlet-name>profile</servlet-name>
<url-pattern>*</url-pattern>
</servlet-mapping>
but you're missing that servlet definition like so:
<servlet>
<servlet-name>profile</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
Probably a typo?

web.xml
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
SpringPOC
<servlet-name>profile</servlet-name>
<url-pattern>/profile</url-pattern>
<servlet-name>profile</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
profile

Exception disappeared after I moved the spring jars into the web-inf's lib folder from the web-inf folder.
