NoClassDefFoundError for com.vaadin.data.Property

General
1

Hi,

The problem I have is that I get a ClassDefNotFound exception, even though the class is in the vaadin package and can be used separately ie (Property p = new Property()). I also checked that the vaadin-sqlcontainer.1.1.0.jar package uses the same Property class in the same location. (sqlcontainer jar was taken from vaadin’s official site)

What could be the problem?

Here is the stacktrace:

I have also added my pom.xml in the attachments, it should provide all the necessary version information.

Thank you in advance,

https://dev.vaadin.com/svn/addons/SQLContainer/trunk/demo/src/com/vaadin/addon/sqlcontainer/demo/addressbook/data/DatabaseHelper.java

This is the example code that I am using.

Problem solved by replacing the packages:

import com.vaadin.addon.sqlcontainer.SQLContainer; import com.vaadin.addon.sqlcontainer.connection.JDBCConnectionPool; import com.vaadin.addon.sqlcontainer.connection.SimpleJDBCConnectionPool; import com.vaadin.addon.sqlcontainer.query.TableQuery;

with these:

import com.vaadin.data.util.sqlcontainer.SQLContainer;
import com.vaadin.data.util.sqlcontainer.connection.JDBCConnectionPool;
import com.vaadin.data.util.sqlcontainer.connection.SimpleJDBCConnectionPool;
import com.vaadin.data.util.sqlcontainer.query.TableQuery;

and also removing the following lines:

q1.setDebug(debugMode);
personContainer.setDebugMode(debugMode);
q2.setDebug(debugMode);
cityContainer.setDebugMode(debugMode);
