spring - Frontend jsp form not binding to model: java.lang.ClassNotFoundException -

i have spring/hibernate/maven application, jsp in frontend.

this form:

<form:form method="post" modelattribute="newcase">     <table>         <tr>             <td>project description:</td>             <td><form:input path="projectdescription" /></td>         </tr>         <tr>             <td>project number:</td>             <td><form:input path="projectnumber" /></td>         </tr>         <tr>             <input type="submit" class="orange_black" value="save" />         </tr> </form:form> 

and form tags working (on other pages have similar forms).

and model:

@entity @table(name="case") public class casemodel {      private string projectdescription;      private string projectnumber;       ...getters , setters...tostring().. } 

and controller:

@controller @requestmapping("/")  public class casecontroller {      @requestmapping(value = "/newcase", method = requestmethod.get)     public string getnewcase(modelmap model) {          model.addattribute("newcase", new casemodel());         return "newcase";     }      @requestmapping(value = "/newcase", method = requestmethod.post)     public string createnewcase(@valid @modelattribute("newcase") casemodel newcase, bindingresult result, modelmap model) {          system.out.println(newcase.tostring());                 return "redirect:/dashboard";      } } 

application running normal, regular. adding casemodel hasn't changed anything. when added <form:form> element , binded model, started receiving error:

severe:   exception while loading app : java.lang.illegalstateexception: containerbase.addchild: start: org.apache.catalina.lifecycleexception: org.apache.catalina.lifecycleexception: java.lang.classnotfoundexception: com.project.model.entities.casemodel 

are there ideas doing wrong? thank you.

edit: part of log
