I have been facing this issue with my application(SPRING +JPA+JSP) when i click on search button after selecting my search criteria.My search criteria has two dropdownbox,one textfield,one datepicker.The issue is coming with the value binding to textfield.After clicking on submit,it will make a ajax call with the following url :(It is expected to go to the controller class with the defined method name)

/Enquiry.page?methodName=loadList&
searchVo.selectedDisr.distCode=ALL&
searchVo.selectedSupplier.Code=ALL&searchVo.selectedDateAppr=
&searchVo.selectedproduct=

When i remove the request parameter &searchVo.selectedproduct= , it is working properly.If i keep that the following error is coming. 

Error 500: Handler processing failed&#59; nested exception is    
java.lang.NoSuchMethodError: java/lang/String.isEmpty()Z

But the same code and url is working in tomcat 7 but not working in IBM websphere. I am facing this issue when i deploy my application in IBM WAS server.Please help me.

    Check the JDK used by Tomcat and IBM. There should be difference. IBM has its own JDK. The method is available since 1.6. http://docs.oracle.com/javase/6/docs/api/java/lang/String.html#isEmpty() – CuriousMind May 12 '15 at 14:30
  • Yes,I have removed references to that method and it is working – GrandPa May 12 '15 at 15:19

isEmpty() method was added in Java 1.6. Most probably problem is you are using java 1.5 or lower version
