Problem from defining JavaBean as an attribute inside ActionForm
Hi,
I have the below scenario:
I have a java bean as below:
public class Address
{
private String city;
private String state;
and public getters/setters for the above attributes;
}
and I have the ActionForm as below:
import Address;
public class EmpForm extends ActionForm
{
private String name;
private String empID;
private Address empAddress;
and public getters/setters for the aboev attribute;
}
We are using Struts 1.2.9 and writing the JSP page as below:
<html:form action="/sampleAction.do">
<html:text property="name"/>
<html:text property="empID"/>
<html:text property="empAddress.city"/>
<html:text property="empAddress.state"/>
</html:form>
I am getting the below error while submitting the form:
E SRVE0026E: [Servlet Error]-[BeanUtils.populate]: java.lang.IllegalArgumentException: No bean specified at org.apache.commons.beanutils.PropertyUtils.getPropertyDescriptor(PropertyUtils.java(Compiled Code))
I have read somewhere that Struts version I am using does support the nested attributes for the <html:text> and other tags. Are there any errors in the above code? Please help.
Thanks & Regards,
Chandra.

Hi,
Thanks for getting back to me.
All I was trying to do is getting the inside bean's values along with the ActionForm, so that I can handle those in my Action class.
Please suggest a best way to achieve that.
Thanks & Regards,
Chandra.

As I remember, Struts 1 don't support such evaluation, you can use
Nested Tags [1] , example are here [2]

Re: 'include' struts.xml stuff is broken?
Posted by Wes Wannemacher <we...@wantii.com>.
When you use an include, the entire included document is parsed and
added to the configuration. This means that the included document must
work as if it were a stand-alone configuration file. You'll have to not
only create well-formed struts xml files, but package configuration as
well. If you're going to reuse interceptors, etc., then you'll need to
pull them in with "extends".

You lost me there; once an element (interceptor, stack, whatever) is defined it's available to subsequent elements. The <package...> documentation [2] describes the use of the "extends" attribute and states:
"The extends attribute is optional and allows one package to inherit the configuration of one or more previous packages - including all interceptor, interceptor-stack, and action configurations."

And was completely unmentioned in the document I was looking at:
http://struts.apache.org/2.x/docs/can-we-break-up-a-large-strutsxml-file-into-smaller-pieces.html
That FAQ should have had a link along the lines of "Full documentation for
include is [here...].
What neither document mentions is how to configure both the top level
struts.xml and the secondary files to avoid duplicating entire interceptor
stacks using packages. 1-2 lines referring to other bits of information
would have been enormously helpful.
I did finally get it working, using an <include> in struts.xml, and in the
included struts.xml, added dtd, a new package definition, and an
'extends=' reference to the parent package.

"Naturally?"
Sniping aside: the "include" documentation [1] states the following:
"Each included file must be in the same format as struts.xml, including the DOCTYPE. The include files can be placed anywhere on the classpath and should be referred to by that path by the "file" attribute."
To me that implies a well-formed, complete S2 config file.

I don't know if "should" is an appropriate word here. It may not meet your expectations, but it works as described, and in some ways is better than a linear include.

'include' struts.xml stuff is broken?
Posted by Dave Belfer-Shevett <db...@homeport.org>.
This seems like it should work, but I'm getting all sorts of hassles, and
the documentation page for this, naturally, provides no examples of what
the include file should look like.
My struts.xml has...
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<include file="struts-editevent.xml">
<package name="CONGO" extends="struts-default">
<interceptors>
[blah blah blah]
</interceptors>
(more actions)
</package>
</struts>
The 'struts-editevent.xml' has:
<action name="coconut/viewEditEvent" method="load"
class="com.stonekeep.congo.coconut.EditEvent">
<interceptor-ref name="mystack" />
<result
name="success">/WEB-INF/jsp/coconut/EditEventForm.jsp</result>
<result name="login"
type="redirect-action">coconut/showloginpage</result>
</action>
<action name="coconut/postEditEvent" method="update"
class="com.stonekeep.congo.coconut.EditEvent">
<interceptor-ref name="mystack" />
<result
name="success">/WEB-INF/jsp/coconut/Maintenance.jsp</result>
<result
name="input">/WEB-INF/jsp/coconut/EditEventForm.jsp</result>
<result name="login"
type="redirect-action">coconut/showloginpage</result>
</action>
A basic block of actions.
I'm getting XML validatoin errors up the wazoo because the
struts-editevent.xml file isn't well-formed. If I put it in <struts>
blocks, I get "you're referencing interceptors that don't exist".
If I try and duplicate the entire package, interceptors, and DTD
definition into the include file, I get package collisions.
My take is the <include> function does not work as described in the
documentation. It should be a linear include, and the resulting document
is parsed by SAX, but that doesn't seem to be happening.
Can someone give me an example of an included XML file that actually
works?
Here are links to what I'm seeing:
My main struts.xml: http://pastebin.stonekeep.com/4955
My struts-editevent.xml: http://pastebin.stonekeep.com/4956
What happens when I deploy:
http://pastebin.stonekeep.com/4957
Note that says "no grammar found". Adding the DTD says "you need a
package name in your struts block" - etc etc etc. It never really
resolves.
Can someone show me an <include> setup that actually works?

Its working now. Thank you very much for the replies.
The problem was that the naming convention (it was like sStreet, sCity and the getter/setters were getStreet, getCity etc.)of my attributes and I did not initialize the inside bean in the ActionForm.

Oh, and another thought: are you initializing ActionForm's empAddress
field somewhere? It may cause problems if it is null when Struts tries
to set its properties. Struts 2 can automatically create instances of
beans in that situation, but Struts 1 doesn't.

What you have below all looks fine; it should work as you expected. What
does your form bean definition look like? Is the form bean correctly
referenced by the action mapping the form is submitted to? Post the
relevant bits of configuration and the full stack trace; maybe that will
allow someone to see the problem.
