Form bean -> null
Hello,
I need to use a form bean in struts and this is the first time I'm doing that .So as newbie I feel I'm missing something basic. Can U help me? This is my case.
I have my struts-config :
<form-beans>
<form-bean name="MyForm" type="provider.test.MyForm"/>
</form-beans>
<action path="/editStream"
type="provider.test.MyFormAction"
name="MyForm"
scope="request"
validate="false">
<forward name="success" path="/streaming.jsp"/>
</action>
I have MyForm Bean with set and get methods and I have MyForm Action which just initializes my form:
.........................
if (form == null) {
System.out.println("Form is null");
form = new MyForm();
if ("request".equals(mapping.getScope()))
request.setAttribute(mapping.getAttribute(), form);
else
session.setAttribute(mapping.getAttribute(), form);
}
MyForm strmform = (MyForm) form;
and finally my .jsp is the following:
<html:form action="/details" >
<tr> <font size="5" color="#0000A0"> Destination IP Address : </font>
<html:text property="ip1" size="3" /> <font color="#0000A0"> . </font>
<html:text property="ip2" size="3" /> <font color="#0000A0"> . </font>
<html:text property="ip3" size="3" /> <font color="#0000A0"> . </font>
<html:text property="ip4" size="3" /> <font color="#0000A0"> . </font>
</tr>
<tr> <html:text property="port" size="3" /> <font color="#0000A0"> </tr>
<tr> <html:text property="lan" size="3" /> <font color="#0000A0"> </tr>
<tr> <html:text property="autostart" size="3" /> <font color="#0000A0"> </tr>
</html:form>
When I callthis page I get a :
javax.servlet.ServletException: Cannot retrieve definition for form bean null
error, and I cannot fingure out what I 'm doing wrong.
I would appriciated if U could provide me with any info regarding this problem.
Thank U in advance,
Konstantina

The more I question the origin and meaning of our existence, the
less I care. And the less I care, the more I question myself.

supposing the logic:iterate id paramenter is set to "element"
It should be something like this
<html:link page="ViewHeadlineAction.do" paramName="element"
paramId="headlineID" paramPropery="getterMethodWhoReturnsX">
instead of the static <a></a>
checks this document http://jakarta.apache.org/struts/struts-html.html for
<html:link> reference doc.
Hope this helps.

Hi ,
>From what I understand you want to create links for each headline and pass
the head line as a parameter.
So inside the logic:iterate tag U should put :
<logic:iterate.................>
<jsp:useBean id="info" class="java.util.HashMap"/>
<%info.put("HeadLineID", "X"); %>
<html:link page="/details.do" name="info"> Headline </html:link>
</logic:iterate>
U can replace the one line of code with <jsp:setProperty ....of the bean
info>
It worked for me.

logic:iterate question
Posted by Oliver Kiessler <ki...@linustar.de>.
hello,
i have a problem on one of my "views" with a logic:iterate tag. i have
an "action" that fetches news headlines from a database
(headline,headlineID) and stores them in a bean
(headlines->Arraylist,headlinedID->Vector) which is appended to
request/session. On the "view" i want to iterate through the Arraylist
with the headlines which basically works fine. but i need to create
links like this: <a href=ViewHeadlineAction.do?headlineID=X>XYZ</a>
how would i use the iterate tag? do i have to use the nested tag? (i am
currently using struts 1.0.2) i dont want to use any "java code" in my
view, only tags...
thanks, oli
