Re: [S2] Beans list in Dynamic form and ParametersInterceptor problem
Hi.
I've solved the problem. And the solution was... reading the documentation
with great attention!!!
In particular, from
http://struts.apache.org/2.0.11/docs/type-conversion.html, the paragraph
"Relationship to Parameter Names":
1 - Use JavaBeans! The framework can only create objects if the objects obey
the JavaBean specification and provide no-arg constructions, as well as
getters and setters where appropriate
2 - Remember that person.name will call getPerson().setName(), but if in
order for the framework to create the Person object for you, a setPerson
must also exist
So: in the bean class, I've added a no-arg constructor; in the action class,
I've added a property Song and a setSong method. And now I'm able to fill
the list of beans modified from the form in the jsp, and use it in the
action.
I summerize all for future benefits.
-Problem: submit a dynamic form created with a list of beans and use these
beans in the action.
-BEAN
Provide a no-arg constructor and getters and setters for all properties.
public class Song implements Serializable {
private String SongId;
private String StartDate;
private String EndDate;
private String StatusLoad;
private String StatusSellable;
public Song(){}
public String getStartDate() {return StartDate;}
public void setStartDate(String startDate) {StartDate = startDate;}
public String getEndDate() {return EndDate;}
public void setEndDate(String endDate) {EndDate = endDate;}
public String getStatusLoad() {return StatusLoad;}
public void setStatusLoad(String statusLoad) {StatusLoad = statusLoad;}
public String getStatusSellable() {return StatusSellable;}
public void setStatusSellable(String statusSellable) {StatusSellable =
statusSellable;}
public String getSongId() {return SongId;}
public void setSongId(String songId) {SongId = songId;}
}
-ACTION
Provide the beans list property with get and set, and a bean property with
set.
public class ResubmitAction extends BaseAction {
private List songs = new ArrayList();
private Song song = null;
public String resubmitCatalog() {
...
//use the beans list coming from the form
if (this.songs != null) {
log.debug("song list size "+songs.size());
Iterator iter = this.songs.iterator();
while (iter.hasNext()) {
Song tmp = (Song) iter.next();
if (tmp != null) {
log.debug("--\n"+tmp.toString()+"\n--");
}
}
}
}
public List getSongs() {return songs;}
public void setSongs(List songs) {this.songs = songs;}
public void setSong(Song song) {this.song = song;}
}
-CONVERSION PROPERTIES FILE
Create a ActionName-conversion.properties file in the same path of the
action,
so in my case ResubmitAction-conversion.properties where
ResubmitAction.class is located.
Element_songs=console.beans.Song
CreateIfNull_songs=true
In the first version of the file there was also the line
KeyProperty_songs=SongId
but this is useless because in the jsp I don't use the unique id
of the bean for iteration throw the list.
-JSP
Create the form using iterator tag and use stat.index to reference the
current iteration index.
Pay attention to the ognl expression.
START DATE
END DATE
STATUS LOAD
STATUS SELLABLE
and the resulting html is (the beans list has 2 elements):
That's all. And I think it's enough...
It was hard, but with an happy end.
Thanks to all for replies to my first post.

RE: [S2] Beans list in Dynamic form and ParametersInterceptor problem
Hi David,
the OutOfMemoryError was solved using %{#stat.index} in the inputs, as
suggested by Laurie Harper.
You're right about the web server heap space, but the cause of the error was
obviously my wrong
ognl expression.
Does this stack trace begin with a java.lang.OutOfMemoryError as well?
Have you tried increasing the heap space size for your Web Server?
Just a thought . . .
Regards,
David Hernandez

Re: [S2] Beans list in Dynamic form and ParametersInterceptor problem
The problem of songs list size is solved using #stat.index. But not the
parameters error.
The list size now is 1, but the element inside is null.
So, it can't create song beans and put it into the list.
In the conversion props file the Element_songs is correctly set to the Song
bean class.
The KeyProperty is useless now using the iterator index?
Here some logs:
DEBUG (interceptor.ParametersInterceptor:148) - Setting params

Reading the manual at
http://struts.apache.org/2.0.11/docs/type-conversion.html it says:
"Notice the () notation! Do not use [] notation, which is for Maps only!"
but changing the notation from
songs[%{#stat.index}].property
to
songs(%{#stat.index}).property
in the jsp, the form isn't populated.

[S2] Beans list in Dynamic form and ParametersInterceptor problem
Hi. I'm having problem in submitting a dynamic form created with a list of
beans.
I'm able to build the jsp with the form and (it seems...) to pass parameters
to action,
but I'm not able to get the correct list of beans after submitting the form.
I've tried with a list of 2 beans. Something really strange happens:
the list in the action is not null (ok, this shouldn't be strange, if I've
done all correctly)
and has a size equals to the id of a bean (and this is really strange, maybe
there's something wrong?...).
Due to the list size, at the end of the action there is also
OutOfMemoryError (Java heap space).
So, is it an ognl expression problem? I've tried many version but without
success.
name="#Song[SongId].startDate"
name="%{#Song[SongId]}.endDate"
name="songs[SongId].statusLoad"
name="songs[#Song.SongId].statusSellable"
name="%{songs[#Song.SongId]}.endDate"
name="%{#songs[Song.SongId]}.statusLoad"
I'm using struts 2.0.11.
Some code:
-ACTION
public class ResubmitAction extends BaseAction {
private List songs = new ArrayList();
public String resubmitCatalog() {
...
if(songs != null) {
log.debug("song size "+songs.size());
}
}
public List getSongs() {return songs;}
public void setSongs(List songs) {this.songs = songs;}
}
-BEAN
public class Song implements Serializable {
private String SongId;
...
private String StartDate;
private String EndDate;
private String StatusLoad;
private String StatusSellable;
...
public String getStartDate() {return StartDate;}
public void setStartDate(String startDate) {StartDate = startDate;}
public String getEndDate() {return EndDate;}
public void setEndDate(String endDate) {EndDate = endDate;}
public String getStatusLoad() {return StatusLoad;}
public void setStatusLoad(String statusLoad) {StatusLoad = statusLoad;}
public String getStatusSellable() {return StatusSellable;}
public void setStatusSellable(String statusSellable) {StatusSellable =
statusSellable;}
public String getSongId() {return SongId;}
public void setSongId(String songId) {SongId = songId;}
}
-CONVERSION PROP
ResubmitAction-Conversion.properties (in the same path of
ResubmitAction.java)
KeyProperty_songs=SongId
Element_songs=console.beans.Song
CreateIfNull_songs=true
-JSP
START DATE
END DATE
STATUS LOAD
STATUS SELLABLE
...
and the HTML is:
and another group of input with the second id 9121591

Cannot access request variable in stack context from jsp
I'm trying to access a variable in stack context form jsp using the struts
tag .
The struts debug tag (in struts2) shows me that the key "request" has this
array/map of values:
{javax.servlet.include.servlet_path=/console/Menu.jsp,
struts.request_uri=/console/View.action, struts.view_uri=/console/View.jsp,
[EMAIL PROTECTED],
[EMAIL PROTECTED],
[EMAIL PROTECTED],
javax.servlet.include.request_uri=/console/Menu2.jsp,
javax.servlet.include.context_path=/}
but if I try to write the value of struts.view_uri in the jsp using the tag
nothing appears. I've also
tried to use without
results.
Am i using in a wrong way the ognl syntax?
Thanks.

Failed while destroying filter during shutdown
I've deployed a webapp with struts2 on weblogic 8.1/java 1.4.1_02. It works fine, but when I make a redeploy it throws an exception with the following two stack traces. The NoClassDefFoundError seems strange to me, because the two jars struts2-core.jar and backpost-util-concurrent.jar (for retrotranslation of struts2) contain the classes correctly. Maybe something related with weblogic? Thanks.
