How to create a costume struts2 tag? any demo?
Hello all,
I create a simple tag following this link
http://joshuajava.wordpress.com/2008/12/27/creating-custom-components-with-struts-2/
http://joshuajava.wordpress.com/2008/12/27/creating-custom-components-with-struts-2/but,
I am trying to add some extra functions into that tag.
Actually, I create a template/simple-theme named:lab.ftl
the content:
a href=#${parameters.name?html}/a
But, finally failed, I add a method:evaluateExtraParams, I have no clue at
all.
Brilliant Thanks
@StrutsTag(
name=tab,
tldTagClass=lab.struts2.components.Hello,
description=Render a checkbox input field
)
public class Hello extends Component {
protected String name;
public Hello(ValueStack stack) {
super(stack);
}
public String getName() {
return name;
}
@StrutsTagAttribute(description=The actual HTML value attribute of the
checkbox., defaultValue=true)
public void setName(String name) {
this.name = name;
}
public boolean start(Writer writer) {
try {
writer.write(Hello + name);
} catch (IOException e) {
e.printStackTrace();
}
return true;
}
protected void evaluateExtraParams() {
if (name != null) {
addParameter(name, findString(name));
} else {
addParameter(name, );
}
}
public boolean end(Writer writer) {
return true;
}
@Override
public boolean usesBody() {
return false;
}
}
Regards,
Mead

Re: How to create a costume struts2 tag? any demo?
Hi Lai:
I readed some source code of Struts2, and realized that
the property [theme] is defined in class [org.apache.struts2.components.UIBean]
but not in class [org.apache.struts2.components.Component].
So i think if you want to render something with your tag, and
appoint the theme by the attribute [theme], maybe you should
extend your tag class from [UIBean] instead of [Component].
Which means, your class should like:
public class Hello extends UIBean {
...
...
}

Thank you again. Any Demo or tutorial? I search all of the Struts2 document, but find nothing.
Re: How to create a costume struts2 tag? any demo?
Hi Lai: I used to read the documents of Struts2, but mostly it can't answer my question. So i had to read the source, or debug it. For your question, i think you should read the source code of classes in package [org.apache.struts2.views.jsp.ui]. Get a look at the entire Class Hierarchy before you can choose a right class as your super class. I guess [org.apache.struts2.views.jsp.ui.AnchorTag] is a good sample for you, since you likes trying to render an [a] tag of html. 2010/10/9 Mead Lai laiqi...@gmail.com: Thank you again.

Re: How to create a costume struts2 tag? any demo?
The same error, I have modified the extends class to BaseUI JasperException: /demo.jsp(14,4) Attribute theme invalid for tag hello according to TLD I ref the ui.CheckBox.java, but confused me. Thanks for your replies, All of them inspirit me very much. I will look insight source. Appreciate you.
Re: How to create a costume struts2 tag? any demo?
Hi Lai: Of course you should extend your class from [BaseUI], so you can inherit the property [theme] in your class. But also, you should define the attribute [theme] (and all the other attributes you want to use) in you TLD file, or the jsp compiler can not recognize it in your jsp. You can read the tld file of struts2 ([struts-tags.tld]) as a sample. [struts-tags.tld] can be found in file [struts2-core-2.2.1.jar/META-INF/struts-tags.tld]. 2010/10/9 Mead Lai laiqi...@gmail.com: The same error, I have modified the extends class to BaseUI JasperException: /demo.jsp(14,4) Attribute theme invalid for tag hello according to TLD I ref the ui.CheckBox.java, but confused me.

Create Text Box Dynamically
Hi, I want to create 'n' text box dynamically, the 'n' should comes from database Whether 'n' should be 3 or 4 or 12 it will be vary dynamically and decided by the end user. Is it possible to create 'n' text Box dynamically or at run time with struts2, Also how text box can be accessed because i don't know the name! suppose I want to access a specific text box? Thanks,Vinodh
Re: Create Text Box Dynamically
Hi
I think you can use tags looks like this:
s:iterator var=counter begin=1 end={n}
s:textfield name=data /
/s:iterator
to generate 'n' text box dynamically.
The html code should be:
input type=text name=data
repeats 'n' times.
When user input text in these text boxes and
submit the form, the request should
include several parameters which has the
same name data and the different value.
I think the Action class should have
a property named [data] (same as the name of input tag),
and the data type of this property should be
array of String, so it can hold all the value input
in the text boxes.

Re: Create Text Box Dynamically
Better to use a Collection, but may not matter much.
Also, if order needs to be guaranteed, use index notation (square
brackets along with an index). If you need to add the text boxes
dynamically (via JavaScript) just create DOM elements that match the
HTML generated by the S2 tags.

[S2] How to add a custom parameter to an existing Struts UI Tag?
I am trying to override a struts tag template (specifically
s:checkboxlist), and I can't figure out how to add a parameter to
the tag. I have successfully overridden the template by copying
checkboxlist.tld to my template/simple directory and all works well.
Now I would like to add a parameter. It appears that I need to
override the the META-INF/struts-tags.tld file because I keep getting
the error below. However, using the same method as checkboxlist.tld,
I copy a modified version of struts-tags.tld to my
META-INF/struts-tags.tld directory. However, I still get the same
error below. Not sure if I need to modify another file or if
struts-tags.tld cannot be overridden. Anyone given this a try?
Trying not to have to create a new custom tag since all I want is a
simple modification to checkboxlist.tld.

Re: [S2] How to add a custom parameter to an existing Struts UI Tag?
Do you need to insert a breaking string every 3 items?
I think this approach is too much expansive in term of time.
Furthermore, after that, you should deal with subcassing process.
You should have valid reasons for do that.
Why don't you simply use mod operator?:
s:iterator status=stat value={1,2,3,4,5}
s:if test=(#stat.index % 3)==0

Re: [S2] How to add a custom parameter to an existing Struts UI Tag?
I think encapsulating this kind of behavior in a custom tag is why
custom tags exist--and since the iteration is handled by the
checkboxlist tag internally, using an iterator/etc. doesn't really
work.

Re: [S2] How to add a custom parameter to an existing Struts UI Tag?
Much cleaner to encapsulate the behavior, especially if it's used
often. It might be easier to use a JSP-based tag, though, than to
extend an S2 tag.

I think this approach is too much expansive in term of time.
Furthermore, after that, you should deal with subcassing process.
You should have valid reasons for do that.
Why don't you simply use mod operator?:

I am trying to override a struts tag template (specifically
s:checkboxlist), and I can't figure out how to add a parameter to
the tag. I have successfully overridden the template by copying
checkboxlist.tld to my template/simple directory and all works well.
Now I would like to add a parameter. It appears that I need to
override the the META-INF/struts-tags.tld file because I keep getting
the error below. However, using the same method as checkboxlist.tld,
I copy a modified version of struts-tags.tld to my
META-INF/struts-tags.tld directory. However, I still get the same
error below. Not sure if I need to modify another file or if
struts-tags.tld cannot be overridden. Anyone given this a try?
Trying not to have to create a new custom tag since all I want is a
simple modification to checkboxlist.tld.

Re: [S2] How to add a custom parameter to an existing Struts UI Tag?
Agreed. I think an upgrade to the checklistbox tag is in warranted.
Through my searches there are many posts looking for ways to layout
the checkboxlist better. Most frustrating on this tag is the actual
checkbox and the label will break lines making this unacceptable from
a UI perspective. Also, many users I saw just wanted a one column
format. I would propose surrounding the input type=checkbox and
label html elements in a div tag (you could even supply an
additional class and style attribute to the tag). This way a user
could set widths, floats, etc for the div tag. This hack below did
the trick for me. By setting the div Class properties: float in
combination with width you can easily set up one column lists or
fixed width layouts that extend to the next line easily. Would make
this tag much more versatile - especially with just a small
modification.
#-- Modified checklistbox.tld with surrounding div tag --
div class=myCustomDivClass
input type=checkbox name=${parameters.name?html}
value=${itemKeyStr?html}
id=${parameters.name?html}-${itemCount}#rt/
#if tag.contains(parameters.nameValue, itemKey)
checked=checked#rt/
/#if
#if parameters.disabled?default(false)
disabled=disabled#rt/
/#if
#if parameters.title??
title=${parameters.title?html}#rt/
/#if
#include /${parameters.templateDir}/simple/scripting-events.ftl /
#include /${parameters.templateDir}/simple/common-attributes.ftl /
/
label for=${parameters.name?html}-${itemCount}
class=checkboxLabel${itemValue?html}/label
#-- Add ending div tag --

Re: 2 View, and optional JSON
Why? Is the data returned from the service different from the data you'd return on the page? Even if it is, it's not going to be significantly different, and the pages returning data for html rendering is only going to have slightly more data.

Hi Burton, I see, that would be the problem cause that ERROR. You have to download the struts2 source, and take a look at the both org.apache.struts2.views.jsp.ui.CheckboxListTag and org.apache.struts2.components,CheckboxList. I think you must add the attribute breakCount into CheckboxList.java, then it will work, maybe. I am not sure about that, I am also got the same problem, when creating myself Tag. Good Luck.

Simple theme and field errors
Working on first Struts2 project, and quickly found out that standard themes can produce some quirky output. (Hoping to write my own when I get some time). I decided to simply use the simple theme to give me the most control over HTML formatting. However, it doesn't display field errors from validation. So I tried adding this to jsp where I want the error message to pop up: s:property value=fieldErrors.fname/ ... where fname is the field that failed validation. This works, but the error message always gets rendered back wrapped in brackets: [You must enter a first name] Of course, one could write some nasty code to strip out the brackets, but there must be an easier way.
