I got the problems in validator.

Here the script in struts-config.xml:
<form-bean name=”beverageCreationForm” type=”com.deth.struts.form.BeverageCreationForm” >
<form-property name=”method” type=”java.lang.String”/>
</form-bean>

<action
attribute=”beverageCreationForm”
input=”/tiles/beverageCreation-tiles.jsp”
name=”beverageCreationForm”
path=”/beverageCreation”
roles=”Admin,Manager”
scope=”request”
validate=”true”
parameter=”method”
type=”com.deth.struts.action.BeverageCreationDispatchAction”>
<forward name=”saved” path=”/beverageCreationSuccess.do” redirect=”true” contextRelative=”true”/>
<forward name=”previewed” path=”/tiles/beverage-creation-preview-tiles.jsp”/>
</action>

And in validator.xml:
<form name=”beverageCreationForm”>
<field
property=”name”
depends=”required”>
<arg key=”prompt.name”/>
</field>
<field
property=”price”
depends=”required,mask,minlength,maxlength”>
<arg0 key=”prompt.price”/>
<arg1 key=”${var:minlength}” name=”minlength” resource=”false”/>
<arg1 key=”${var:maxlength}” name=”maxlength” resource=”false”/>
<var>
<var-name>mask</var-name>
<var-value>^[0-9]*$</var-value>
</var>
<var>
<var-name>minlength</var-name>
<var-value>1</var-value>
</var>
<var>
<var-name>maxlength</var-name>
<var-value>7</var-value>
</var>
</field>
</form>

The code in jsp as following below:

<html:form action=”/beverageCreation” focus=”name” enctype=”multipart/form-data” method=”post” onsubmit=”validateBeverageCreationForm(this);”>
<input type=”hidden” name=”method”>
<script>
function setUrl(target) {
document.forms[0].method.value=target;
}
</script>
<table width=”100%” align=”center”>
<tr>
<td>Kind of Beverage:</td>
<td>
<html:select property=”parentBeverageId”>
<html:option value=”1″>WINE</html:option>
<html:option value=”2″>BEER</html:option>
</html:select>
</td>
</tr>
<tr>
<td>* Name:</td>
<td>
<html:text property=”name” size=”50″ maxlength=”50″/>
</td>
</tr>
<tr>
<td>Picture:</td>
<td>
<html:file size=”50″ maxlength=”50″ property=”theFile”/>
</td>
</tr>
<tr>
<td>* Price:</td>
<td>
<html:text property=”price” size=”32″ maxlength=”50″/>
</td>
</tr>
<tr>
<td>Unit:</td>
<td>
<html:select property=”unitId”>
<html:option value=”4″>Bottle</html:option>
<html:option value=”5″>Can</html:option>
</html:select>
</td>
</tr>
<tr>
<td></td>
<td>
<html:submit value=”Preview” onclick=”setUrl(‘preview’);”/>
<html:submit value=”Save” onclick=”setUrl(‘save’);”/><html:reset/>
</td>
</tr>
<tr>
<td>Note: * indicates required field.</td>
</tr>
</table>
<html:javascript staticJavascript=”true” dynamicJavascript=”true” formName=”beverageCreationForm”/>
</html:form>

When on submit the form, JavaScript works fine. But it makes forward to the target page, instead of the input. Here is the errors:
javax.servlet.ServletException: For input string: “”
org.apache.struts.action.RequestProcessor.processException(RequestProcessor.java:523)
org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:421)

deth.i18n.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:111)
org.displaytag.filter.ResponseOverrideFilter.doFilter(ResponseOverrideFilter.java:125)

root cause

java.lang.NumberFormatException: For input string: “”
java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)

I compared the last my project, there was no this problem. Please help. Thanks.
Best regards, Khoa.
