Struts not parsing HTML correctly?
There are actually 2 problems I'm experiencing:
Firstly, I have the following snippet in one of my forms (user_add.jsp):
<!-- tr>
<th>Contract User</th>
<td>
<html:checkbox property="contractUser"/>
</td>
</tr -->
If this is present, struts fails with the following error:
org.apache.jasper.JasperException: No getter method for property contractUser
of bean org.apache.struts.taglib.html.BEAN
This happens whether that section is commented out or not, but does not occur
if I remove the code entirely.
The second problem is that I actually DO have a getter (and setter) method for
contractUser in UserForm.java:
/* Contract User */
private boolean contractUser = false;
public boolean getContractUser() {
return this.contractUser;
}
public void setContractUser(boolean contractUser) {
this.contractUser = contractUser;
}
I have the following in my struts config:
<struts-config>
<form-beans>
...
<form-bean name="userForm"
type="com.somewhere.aproject.UserForm" />
...
</form-beans>
<action-mappings>
...
<action path="/screen_user_add"
forward="/user_add.jsp"
name="userForm"
validate="false"/>
...
</action-mappings>
</struts-config>
I know the configuration is right since the rest of the fields work fine.
Should I be using type String instead of boolean for contractUser?

Actually, once I explicitly specified what form to use within the jsp page
(using the name and type attributes of the html:form tag), it worked fine,
but it seems weird to have to specify what form to use both in the jsp page
and in struts-config.xml.

My impression was that if you used the "forward" attribute that the
Action class would not be instantiated and called, instead that it would
forward directly to the JSP page.
Does the error occur if you use "input" instead of "forward"?

^^^^^^^^^^^^^^^
Try removing that.

Problems with the iterate tag
Posted by Karl <ka...@webartjapan.com>.
I'm trying to get my jsp page to iterate over a collection of objects,
printing one object property (data) on every line.
I've tried implementing the following:
test.jsp:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
<html:html>
<head>
<title>Test</title>
</head>
<body>
<logic:iterate id="element" name="testContainer" property="testData">
<bean:write name="element" property="data"/>.<br/>
</logic:iterate>
END<br/>
</body>
</html:html>
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TestForm.java:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
package com.somewhere;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.*;
import java.util.*;
public final class TestForm extends ActionForm {
private Collection myCollection;
{
myCollection = new Vector();
myCollection.add(new TestData("1"));
myCollection.add(new TestData("two"));
myCollection.add(new TestData("III"));
}
public Collection getTestData() {
return myCollection;
}
}
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TestData.java:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
package com.somewhere;
public final class TestData {
private String myData;
public TestData(String value) {
myData = value;
}
public String getData() {
return myData;
}
}
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
struts-config.xml:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
<struts-config>
<form-beans type="org.apache.struts.action.ActionFormBean">
<form-bean name="testContainer" type="com.somewhere.TestForm" />
</form-beans>
<action-mappings type="org.apache.struts.action.ActionMapping">
<action path="/do_test" forward="/test.jsp" name="testContainer"
validate="false"/>
</action-mappings>
</struts-config>
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
However, when I try to run this, it fails:
vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
org.apache.jasper.JasperException: No getter method for property data of bean
element
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
It must be something with either "element" being the id of the iteration or
the name of the write tag, but I can't see any other way that I'd tell it to
access the correct data.

You may have a look to the display tag lib who provide an
really easy to use purpose for your use case.
I show you an sample code I use in my view I got :

}
if ("request".equals(mapping.getScope() )) {
request.setAttribute(mapping.getAttribute(), form);
}
else {
HttpSession session = request.getSession();
session.setAttribute(mapping.getAttribute(), form);
}
}
catch (Exception ex) {
System.out.println(ex.getMessage());

return mapping.findForward("success");
}
public ActionForm buildStudent (String name) throws Exception {
Student student = Student.getStudent (name);
form = new StudentForm ();
form.setIdPersonne (student.getName ());
form.setIdPersonne(student.getIdPerson ());
form.setName(rs.getString ("nom"));
........
return form;
}
I added in my struts-config :
<action
attribute="studentForm"
name="studentForm"
path="/getstudent"
scope="request"
type="soft.ibmss.struts.action.GetstudentAction"
validate="false">
<set-property property="secure" value="false" />
<forward name="success" path="/form/editstudent.jsp" />
</action>
Then I define an editstudent action to retrieve the updated data from
the editstudent view page.

Design issue: forms and iterations on the same page
Posted by Karl <ka...@webartjapan.com>.
I'm trying to figure out a good design strategy for building a page that
allows viewing, adding, editing, and deleting of administrators.
At the top of the page I have the form itself:
<html:form action="screen_manage_administrators.do"
name="AdministratorUserForm"
type="com.somewhere.aproject.AdministratorUserForm">
<table>
<tr>
<th>Name</th>
<td>
<html:text property="userName" maxlength="16"
size="16"/>
</td>
</tr>
<tr>
<th>Password</th>
<td>
<html:password property="password" maxlength="8"
size="8"/>
</td>
</tr>
<tr>
<td>
<html:submit value="Set"/>
</td>
</tr>
</table>
</html:form>
Under that I want a list of existing administrators (there will probabl only
be 5-10 admins, and definitely not more than 20):
<table>
<tr>
<th>Name</th>
</tr>
<tr>
<td>
me
</td>
<td>
<html:link
href="screen_manage_administrators.do?num=0">Edit</html:link>
<html:link
href="do_administrator_remove.do?num=0">Delete</html:link>
</td>
</tr>
<tr>
<td>
myself
</td>
<td>
<html:link
href="screen_manage_administrators.do?num=1">Edit</html:link>
<html:link
href="do_administrator_remove.do?num=1">Delete</html:link>
</td>
</tr>
</table>
If you enter in data that does not match an existing administrator name and
submit it, it adds the administrator.
If you click on the "edit" link of one of the administrators, it puts that
admin's details into the edit form.
If the administrator name matches an existing name, the data is updated.
If you click on delete, it will ask confirmation and then delete the entry.
My first question is: Is it a good idea to be placing all of this
functionality in one page, or should I be spreading it to other pages?
My second question is: How would I implement such a layout in struts?
I can associate a UserForm object with the form, but how would I interpret
which administrator data to load into the edit form (via the argument "num")?
Should I be making a separate form object to provide the list of
administrators and then iterate over that list? If so, how do I access 2
different ActionForms within the same page?
Would I be better off making an ActionForm that contains all of the data for
the edit form as well as the collection of administrator data?
Cheers!

I tried it with boolean before, but it didn't work, so someone on the list
said I should implement it as String... and it still doesn't work =(

I've implemented your recommendations but it's still complaining =(
I now have the following in user_add.jsp:

<html:html>

<html:form action="screen_contract_edit.do">

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

...
/* Contract User */
private String contractUser = "false";
public String getContractUser() {
return this.contractUser;
}
public void setContractUser(String contractUser) {
this.contractUser = contractUser;
}
...
}
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
And the following in struts-config.xml:

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I have other properties in the form as well. The page works fine with the
rest of the properties (which are all text edit fields), but as soon as I
add
in this checkbox, it starts complaining:

As "<!-- -->" is HTML comment, it will not change the way jour JSP compiler
handles custom tags.

Yout <html:checkbox> is looking for a getter method for property
contractUser (String getContractUser()) of the current formBean defined by a
parent <html:form>.
How are you using <html:fom> tag in your JSP ? Is the declared action path
associated with the correct ActionFormBean in struts-config ?

But isn't JSP an XML based markup? <!-- --> is used for comments in XML as
well...

Actually, you can use html comments to remove tags you just have to
embed them in the tag...thusly:
<!--bean:write name="foobar" property="nothing"-->
That will be ignored by the container, browser and everything else.

Struts doesn't care of HTML comments, all the JSP source is processed to
produce HTML content, and that's the navigator which is checking HTML
comments to display contents or not.

I've read somewhere that all forms fields should be declared as String
in
the Form classes... It is recommended to make the conversions in your
actions classes.

Struts doesn't care of HTML comments, all the JSP source is processed to
produce HTML content, and that's the navigator which is checking HTML
comments to display contents or not.
