Struts messages are not displayed in JSP
Hi,
I gies a strange problem, the messages are not
displayed. here is the code in my Action:
----
messages.add(ActionMessages.GLOBAL_MESSAGE, new
ActionMessage ("templates List error"));
saveMessages (request, messages);
----
In JSP:
----
<font color="blue" size=2>
<logic:messagesPresent message="true">
<html:messages id="messages" message="true">
<li><c:out value="${messages}"/></li>
</html:messages><br>
</logic:messagesPresent>
</font>
----
however, the messages are not displayed when the code
is indeed executed.
Instead, I saw error in log file:
----
javax.servlet.jsp.JspException: ServletException in
'/WEB-INF/tiles/DisplayTemplate.jsp': Cannot find bean
messages in any scope
......
----
I thought the 'messgaes' is already in request scope.
And more strange, I also find the error message in log
file:

I am debugging on one PC, so I do not understand the
'Connection reset by peer' error.
It seems that this error is cause by the following
display tag - however, I can see the page rendered
correctly:
----
<html:form action="/admin/TemplateManagerAction">
<display:table name="listTemplates" pagesize="10"
id="templates" sort="list" export="true"
requestURI="/Canal/admin/TemplateManagerAction.do">
<display:setProperty name="basic.empty.showtable"
value="true"/>
<display:column media="html"> <input type=checkbox
name="value(<bean:write name="templates"
property="name"/>)" value="x"/> </display:column>
<display:column title="Name" property="name"
sortable="true"
href="TemplateManagerAction.do?method=View"
paramId="name"/>
<display:column title="Description"
property="description"
href="TemplateManagerAction.do?method=View"
paramId="name" paramProperty="name"/>
<display:column title="Category"
property="category" sortable="true"
href="TemplateManagerAction.do?method=View"
paramId="name" paramProperty="name"/>
</display:table>
<html:submit property="method"><bean:message
key="button.remove"/></html:submit>
</html:form>
------
I have no idea now.
appreciate your help !
