Pagination with struts 2.x
Hi, What is the best approach to display database table content page wise using struts 2? We used display tag few years back, but there seems another taglib pager taglib. Is pager tag lib a better option or is there any inherent support in struts 2 for paging?

[S2] encode attribute of : correct encoding?
I fail to understand how to use the "encode" attribute of the . Here's an example that puzzles me... Let's try, alternately, to set "encode" to "true" and "false". Here goes: Élizabeth yields: /myAction?entityName=%C3%83%C2%89lizabeth while Élizabeth yields /myAction?entityName=%C3%83%C2%89lizabeth which is exactly identical to the previously generated URL! Therefore what is the point of the "encode" attribute? Moreover, when 'myAction' retrieves the 'entityName' parameter, it converts it to: "Ãlizabeth". ??? BTW, when Google encodes the query string "Élizabeth" (without the quotes), it does so as: http://www.google.com/search?q=%C9lizabeth * * * My setup: Tomcat 6.0.16, Java1.6.0_11, Struts 2.1.6 The JSP page where the tag appears contains the following lines (each in its proper place): <%@ page contentType="text/html;charset=UTF-8" language="java" pageEncoding="UTF-8" %> I have a Tomcat encoding filter that sets each request's encoding to: "text/html;charset=UTF-8" - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Re: Type conversion exceptions
I got your code to run (paseted below). Just so I am sure I am doing what you
are trying to do:
1. I made no changes to Setter or SetterList so that I don't break your design.
Only to the action and the jsp
2. I assume what you want is to be able to display and edit and create the
settings (I did not do delete)?
3. I assume you are using Struts 2.1.6 (I should have asked -- sorry)
Some observations:
1. You don't need a converter at all.
Why? Because you are sending the title and value as separate Strings and want
to create a Settings object with those items as its state. Instantiating an
object and injecting it with a couple of Strings does not require a converter.
If you have a String representation of the Setting as a whole (e.g.
"theTitle&theValue) then you would need a converter to parse the String and
create a Setting object.
2. You don't need entries in *-converters.xml
Why? Becaus of 1.
3. You don't need to expose?a property of type StringList.
Why? Your JSP only uses the fact that it is a List. StringList is an
implementation. So you only need a getter/setter that returns/takes a
?List?
Note: I am posting from Japan and I noticed I sometimes get characters that are
non-printing here appearing in the paste -- I think it is the encoding so
please clean it up if that happens
Action:
public class SettingAction extends ActionSupport {
?private static final long serialVersionUID = -7082992787920559583L;
?private Setting newSetting;
?private SettingList settings = new SettingList();
?public String execute() {
??if (newSetting != null) {
???//give it an id
???newSetting.setId("" + settings.size());
???settings.add(newSetting);
??}
??return SUCCESS;
?}
?public void setSettings(List settings) {
??this.settings = new SettingList();
??for (Setting setting : settings) {
???this.settings.add(setting);
??}
?}
?public List getSettings() {
??return settings;

Here is the converter code: http://pastie.org/419709
Obviously it isn't doing anything other than outputting the values being
passed in, but none of the values contain anything yet as the parameters are
getting lost somewhere so there's no point in processing them yet.

Jetty 6.x vs Tomcat 6.x
Guys -- I have a loaded (Hibernate, Spring, Tiles) S2.1.6 application running on TC 6 and I want to speed up the development cycle. I have exhausted the trials to get TC 6.x to dynamically reload modified class changes and have reached the point where I have installed Jetty 6.x. My application is "sort of" running when deployed in that environment, however, there seems to be a strange phenomenon concerning JSP page compiles containing S2 tags. Is there an issue concerning the two JSP compilers?

File upload, validation and Preparable
Got a couple questions about file uploading. I've discovered that in the standard interceptor stack "fileUpload" is after "prepare" interceptor. This means that the upload File, ContentType, and FileName setters have not been called before prepare() method runs. Is there a good reason for this? It seems like fileUpload should be before prepare so that these "parameters" have been set and are available to the prepare() method. What do you think? One of the problems I'm having is that if the page fails validation (on some other field) then the user selection in the tag is lost. The result="input" takes me back to the page but the File selection is blank. Is there a way to preserve the users file selection when validation fails? If I do a show source on the page after validation fails the input file tag has it's value= attribute set the temp file name from the server. This doesn't seem right? This is leaking server configuration (albeit not very important) information back to the client.
Re: struts 2.1.6 verbose logging
When a property is not found, it is logged, which causes all those
warnings, as for myself I find them very annoying. I have a patch
somewhere collecting dust, that throws exceptions when a property is
not found, or there is an error evaluating an expression in a tag. I
think we should take that route and only show errors when they happen
in tags and not the stack in general (which produces all this noise)

struts 2.1.6 verbose logging
"Struts 2.1 introduces more verbose logging than Struts 2.0. While
extremely valuable, some users may find these annoying."
http://cwiki.apache.org/S2WIKI/troubleshooting-guide-migrating-from-struts-20x-to-21x.html
The extremely annoying thing is that struts 2.1 emits those warnings
(apparently) for each struts2 ui tag in each jsp page. ("Could not
find property [templateDir] ")
In fact, a few (20 or 30) requests in my web application results in a
lot (about 1000) of warnings which are not (AFAIK) related to my
application, but to struts internals.
I like to be warned of missing properties in the stack, as they might
point to missing properies in my actions or bad spelt jsp tags... but
this is not very useful:
# tail -n 2000 /usr/local/tomcat/logs/catalina.out | grep "Could not
find" | sed 's/http.* //' | sort | uniq -c
24 WARN [[.freemarker.Request]
24 WARN [[.freemarker.RequestParameters]
29 WARN [[org.apache.catalina.jsp_file]
29 WARN [[struts.valueStack]
864 WARN [[templateDir]
192 WARN [[theme]
And no solution is provided, except for disabling those warnings completely.
I'd like to know if that implies something wrong (or slightly wrong)
about my jsp pages, or about struts.

I haven't read that blog post, but I do know that Spring treats @PersistenceContext differently than an EJB container.

Re: [S2] Struts 2 + Spring 2 + JPA example uses @PersistenceContext - is this a "bad thing"??
Any thoughts on how this would affect the OpenEntityManagerInViewFilter? I assume if you create a new EM for each service/dao operation, the objects would become detached after each method thus giving you a lazy exception for anything in the view - rendering the OpenEntityManagerInViewFilter useless. Am I understanding this correctly?

[S2] Struts 2 + Spring 2 + JPA example uses @PersistenceContext - is this a "bad thing"??
I set up the example for "Struts 2 + Spring 2 + JPA + AJAX" using the OpenEntityManagerInViewFilter from the Struts website and all works well. (http://struts.apache.org/2.0.14/docs/struts-2-spring-2-jpa-ajax.html). It appears this example uses the @PersistenceContext annotation to inject the EntityManger into each Service/Dao class... Then I read this blog about how you SHOULD NOT use @PersistenceContext annotation in a webapp becasue of thread safety unless you implement a SingleThreadModel. http://weblogs.java.net/blog/ss141213/archive/2005/12/dont_use_persis_1.html Now I am confused... Should I instead use @PersistenceUnit to inject the EntityManagerFactor into each Dao object? And if so, won't this affect the OpenEntityManagerInViewFilter and cause Lazy exceptions? Can someone shead some light on this for me or am I not understanding this correctly? Apologies in advance if this is a bit off Struts topic...

RE: Required field only works with text fields?
Dave,
Thanks for the suggestion, I changed the validator to read as:
@ManyToOne(cascade = {CascadeType.PERSIST, CascadeType.MERGE},
fetch=FetchType.EAGER)
@JoinColumn(name = "STATUS")
@FieldExpressionValidator(message = "Default message",
key="validate.status", expression = "status != null")
public Status getStatus() {
return status;
}
The validation is applied, but no message is displayed. With:
@ExpressionValidator(message = "Default message", key="validate.status",
expression = "status != null")
The validation is applied and the validation message appears at the top
of my page where I have an tag.
Is there something else I need to do to make the
FieldExpressionValidator work?

You'd probably need a @FieldExpressionValidator in order for it to be
associated with a field, but this is just a guess.

IIRC its intent is to prevent multiple validation errors for the same
field.

Sitemesh 2.4 and Struts 2.0.14
Hi, First, I apologize if this has already been mentioned, but I recently attempted to upgrade to Sitemesh 2.4 to bad results. I guess in Sitemesh 2.4, the "PageFilter" was deprecated, and all code has been removed. This means that "applyDecorators" method is not being called anymore, which means that the method in VelocityPageFilter never gets called for Velocity files (and Freemarker templates I'd assume). So, I had to revert back to Sitemesh 2.3. I did a brief search, but, didn't see anything (I also looked briefly into Struts 2.1.x plugin, and saw that it was also assuming that the PageFilter is calling "applyDecorators"). Is anybody aware of any efforts to update the Sitemesh plugin for 2.4.x? Thanks, Dan Slack Langui Systems Inc.
Re: Type conversion exceptions
Here is the converter code: http://pastie.org/419709 Obviously it isn't doing anything other than outputting the values being passed in, but none of the values contain anything yet as the parameters are getting lost somewhere so there's no point in processing them yet. musomesa wrote: > > I have downloaded your code and will study it so that I don't > misunderstand.

Re: redirect parameters lost when using convention plugin 2.1.6
The problem is that "redirect" does not not use "params", only
"redirect-action" does. So to use redirect, you need to do something
like(or set "location" in the annotation):
/someurl.action?myparam=%{somevalue}
and yeah, the documentation is wrong, and this is not consistent. I
will update redirect to be similar to redirect-action.

Theme Selection Options
Hi,
I have a jsp with a custom theme set on my form tag like this . "myxhtml" is our custom theme extends
xhtml theme.
I extended the Struts2 basic TextFieldTag to toggle it based on the custom
visible property. Everything is working fine but I end up getting a empty
row b/w two controls if the visiblity is false... I tried to overcome this
by setting the "simple" theme programatically in the tag class like this
if(visible){
textField.setCssStyle("visibility:visible;");
} else {
textField.setSize("0");
textField.setCssStyle("visibility:hidden;width:0px;height:0px;");
textField.setLabel(null); // Label should be
empty when field is hidden
textField.setKey(null); // I18n key should also
be empty for the given
field
textField.setTheme("simple");
}
but this is not working, it still shows the additonal empty row of data by
adding
"input tag with hidden visibility". I expect this tag to
just print out a "input tag with hidden visibility" becase I set the theme
as "Simple" if visible property is false..
Can anybody let me know where i'm going wrong here?
Regards,
Muthu
