already deleted from the properties in Web Development Assembly so my...
org.eclipse.wst.common.component.xml structure is
<?xml version="1.0" encoding="UTF-8"?>
<project-modules id="moduleCoreId" project-version="1.5.0">
<wb-module deploy-name="simsibs">

<property name="context-root" value="simsibs"/>
<property name="java-output-path" value="/simsibs/build/classes"/>

</project-modules>
also in the buildpath I unmaked the Allow output folder for source folders
