java.lang.Exception' threw an unexpected exception: java.lang.NoClassDefFoundError: com/ibm/icu/text/SimpleDateFormat

[Davide Micheletti]

Like title i've these error in run-mode on a tomcat server..

I've found some solution googling it but i don't want to import any .jar lib if it possible.

So, what can i do?

Thanks

Davide..

What's the stacktrace? Which class/method are you using that causes that error?

SimpleDateFormat however here the log:

If you do use SimpleDateFormat from ICU (com.ibm.icu.text.SimpleDateFormat, as opposed to java.text.SimpleDateFormat), then you have to ship it within your WAR.

Out of curiosity, what's at com.pannelli.controllo.server.GreetingServiceImpl.SQL_fasi_ciclo_per_tipologia(GreetingServiceImpl.java:707) ?

[Davide Micheletti]

com.pannelli.controllo.server.GreetingServiceImpl.SQL_fasi_ciclo_per_tipologia(GreetingServiceImpl.java:707) 

com.pannelli.controllo.server is the package of the server

GreetingServiceImpl is the java class for the server

SQL_fasi_ciclo_per_tipologia(GreetingServiceImpl.java:707)  is a function on the server who start at line 707

However i have to change only the library??

:)) Thomas meant what source code is at that line 707.

I think you just have mistakenly chosen the wrong import of SimpleDateFormat. gwt-user.jar contains com.ibm.icu.text.SimpleDateFormat but gwt-user.jar will not be deployed on the server. I think you want to change the import to java.text.SimpleDateFormat in your server side class.

[Davide Micheletti]

ok thanks.. i'll try your solution.. However sorry for my stupid questions but i'm a newby on GWT and java.. ;) The source Code at line 707 is something like this:

SimpleDateFormat df = new SimpleDateFormat("dd/MM/yyyy");

String data = "04/02/2014";

Date d = df.parse(data);

Ok now there is another error.. Now for CalendarUtil.addDaysToDate()  i think...

SOURCE CODE:

SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");

Date end_date = formatter.parse(prima_data);

CalendarUtil.addDaysToDate(end_date, 5);

String ultima_data = formatter.format(end_date);

CalendarUtil is a GWT class that can not be used on the server. Use java.util.Calendar or JodaTime library.

You can avoid these issues by not blindly use classes available in Eclipse/IntelliJ. Only classes from jar files in war/WEB-INF/lib are available on the server.
