ClassCastException com.dev.model.Form cannot be cast to java.lang.String

2009-03-24 Thread foward


Hello,

I don't know if I m right posting here this, but I have this problem with my
webapp and I couldn't find a solution I hope you can help me please:

ERROR [httpSSLWorkerThread-8080-1] ActionComponent.executeAction(259) 
java.lang.ClassCastException: com.dev.model.Form cannot be cast to
java.lang.String
at
com.opensymphony.xwork2.DefaultActionInvocation.invokeAction(DefaultActionInvocation.java:409)


I did search looking for an answer but I didnt find nothing... the thing is
when I call an action method in a view:

s:action name=createForm!getForm id=action namespace=default/
div id=box
pstrongSurvey : /strong ${form.name}/p
pstrongIntroduction : /strong ${form.introduction}/p
pstrongClose Date:/strong ${form.close_date}/p
br/
/div
 
to show information about one Form.

Please if you can guide me to solve this, Thanks in advance!

Best Regards

Method getForm() return object Form or String? Struts is expecting
that action will return a String not an object. I think you should
read some tutorial how to use Struts 2.

2009-03-24 Thread Jim Kiley

Look at your execute() method or whatever method you're calling from your
JSP.  I suspect that you are returning a com.dev.model.Form object instead
of a String like success or input.

2009/3/24 foward fow...@gmail.com:

 id is obtained and returned.

You put method getForm() in s:form as a action, which means such
method will be called by Struts 2 and the framework will expect a
String - result name, which you have to define in struts.xml.
You shouldn't return an object like Form. To do that, implement
ModelDriven interface and return your Form object from method
getModel() and in your jsp use ${name} instead ${form.name}

 Yes I m reading a book struts in action, I don't know if you recomend me a
 good one.

That is good one

you have 2 different tags you are implementing:

form (tag) which creates a form
http://struts.apache.org/2.1.6/docs/form-tag.html

action (tag) which identifies ActionClass (and possible parameters)
http://struts.apache.org/2.1.6/docs/action.html

did you have a question on either implementation?

Re: OGNL ClassCastException

2009-02-16 Thread Adam Hardy

I use Sets too and they're not the problem here.

The reason why this bug occurs is because the proxy that is returned by my
entity bean is not recognised as an ArrayList by OGNL. Rather OGNL sees it as a
Collection. I guess this is just a rare situation and a difficult one to follow.
In this context on a stand-alone OGNL basis, it's not a problem.

The problem is that struts.xml in the struts jar configures ognl to use
XWorkCollectionPropertyAccessor for Collections and this class is badly
mis-named. It is unable to deal with Collections that are Lists, because it
extends ognl.SetPropertyAccessor which casts the Collection to a Set, causing a
ClassCastException when acting on a List.

In fact there is no ognl.CollectionPropertyAccessor so I created one and for now
I'm going to override struts-default.xml to set OGNL to use my own
XWorkCollectionPropertyAccessor.

I appreciate that this is an edge case, but if you look at struts-default,
you'll see the bean for type ognl.PropertyAccessor name=java.util.Collection and
name=java.util.Set are the same and you'll appreciate the problem straight away
when you look at the base class ognl.SetPropertAccessor.

I'd be happy to enter a Jira, but the question is where: OGNL, XWork or Struts?

Actually I'm having problems getting my version of struts-default.xml to be
read. I thought I had to reference the file in struts.properties and have both
in my classpath:

struts.configuration.files = atomic-struts-default.xml

but that doesn't work.

This is the incoming HTTP parameter:

ListPropertyAccessor).

Is there anything I can do to influence that?

Re: OGNL ClassCastException

2009-02-16 Thread Adam Hardy

I figured out how to get my struts-default.xml to be loaded, in case you were
going tell me how after I asked :O

Consequently discovered that XWorkCollectionPropertyAccessor is actually
compiled into Struts2 / XWork to allow work-arounds for OGNL, so it's not
configurable.

I'll build my own struts jar with modified source.

2009-02-14 Thread Adam Hardy


Yes, it is a JPA entity bean proxied by OpenJPA.

It has a list property - the bean is a parent in a parent-child relationship and 
this property is the list of children.


This is the incoming HTTP parameter:

portfolio.weightings[0]=123

Despite debugging it I am still not sure what has happened but I do see that 
OgnlRuntime looks up the appropriate PropertyAccessor in a map, and gets the 
wrong one back (SetPropertyAccessor instead of ListPropertyAccessor).


Is there anything I can do to influence that?

Adam

ClassCastException: org.apache.struts.taglib.html.MessagesTei

2009-02-03 Thread Ken Bowen


Hi,

I have an old app which was developed under struts 1.2.8 using struts- 
tiles, and has undergone steady development.
However, /AS FAR AS  I KNOW/, no changes to the tags library files  
have been made for a long time.
Yet today, after rebuilding the project (using Project  Clean in  
Eclipse), I suddenly am getting this exception:


java.lang.ClassCastException: org.apache.struts.taglib.html.MessagesTei

(The full exception is shown at the end of this message)  I don't  
recall ever seeing this before, and am not sure what to do to solve  
the problem.


I'll greatly appreciate any suggestions anyone can offer.
Thanks in advance,
Ken Bowen

I put some @Conversion(), @Element(value = java.lang.Long.class) and
@TypeConversion(rule = ConversionRule.COLLECTION, converter =
java.lang.Long) in my Action and it's not working better.

So I set the convertion in a properties file with :
Element_idsCommerciaux=java.lang.Long

and it is working, thanks Ralf.

I tried to put v2.1.6 but I had a lot of trouble with EL expression (s:if
test=${}, s:if test=#session...) which seemed to have changed, but I see
nothing in the docs, release ntoes or migration guide, so I gave up (600 JSP
to change and no time to do it)

Thanks for your help.

EL expressions attributes of struts tags which are evaluated on the
ValueStack are a security risk. See [1].

Outside from struts tags you can still access objects on the
valuestack, as struts intercepts the lookup to the page context. For
the other way around you have to fully markup when you want to access
the page context and such. ( foo=#attr.bar ).

 so I gave up (600 JSP
 to change and no time to do it)

Take peace and comfort in the fact that you're not the only one who
has/had to do this :-)

Random ClassCastException : I'm expecting Long, Struts gives me String on some servers...

2009-01-29 Thread mleneveut


Hi all,

I have a very strange thing. I have a multiple select in my JSP, and a
ListLong of ids in my Action. When I submit the form, I iterate on that
List of Long, and I have this error :

java.lang.ClassCastException: java.lang.String

Struts has String in the List instead of Long. The strange thing is that it
appends on some servers (TomCat 5.5) but not on other : it works on my local
computer, bug on the test server, works on the production server, and works
on all other servers.

I first thought it was a Struts dtd cache version problem on the Eclipse of
the person building the WAR, but I have the same problem on my Eclipse
(which build working WAR for other servers).

We copied all jars files from shared/lib of a working TomCat to the bugging
TomCat, but it doesn't fix the problem.

Did someone already see such a thing ? Do you have an idea of where it could
bug ?

Thanks a lot.

Here is my code :

JSP : (id is a long, nomComplet is a String)
s:select   id=selectCommercial
name=idsCommerciaux 
list=listCommercial
listKey=id
listValue=nomComplet 
cssStyle=width: 200
emptyOption=true
multiple=true
size=10
/s:select

Action :
private ListLong idsCommerciaux;
public ListLong getIdsCommerciaux() {
return idsCommerciaux;
}
public void setIdsCommerciaux(ListLong idsCommerciaux) {
this.idsCommerciaux = idsCommerciaux;
}

for (Long unCommercial : idsCommerciaux) { //ClassCastException here

This seems like a type erasure problem. Reflection is used to set the
entries into the list. As the generic type of the idsCommerciaux list
is not available at runtime  the no convertion to Long takes place for
the List elements. So a List containing Strings is injected. Check out
the Collection and Map Support portion from the type conversion
documentation[1]. You might want use an ObjectTypeDeterminer I think.

 Struts2 version : 2.1.0

You should think about upgrading to 2.1.6, as it became GA recently.

Hi,

Thanks for your reply.

What I can't understand is why it works in some environments, and no others.
The war is the same.

And why do you say that the generic type of the idsCommerciaux list
is not available at runtime ? I defined it as a ListLong in the Action.
So Struts should know that it has to convert the data submitted to Long,
doesn't it ?

Probably because there were known bugs in 2.1.0 (both struts and xwork). 
 As such, it was never intended for general use.  The first GA (General 
Availability) 2.1.x was 2.1.6.  Upgrade to an actual release and *then* 
see if the issue is resolved.  If your bug remains then there might be 
people here motivated to help you.  If you're just trying to find a bug 
that's already been fixed, I wouldn't expect that to motivate the 
*volunteers* here to respond.

Hello,
I have a problem saving a bean User. I use the following code:

UserDao dao = new UserDao();
User user = new User();
Service.populate(user);
dao.save(utente);
if(user != null){
return SUCCESS;
}

here is the dao.save method:

public User save(User user){
Utente newuser = null;
begin();
newuser = (User)getSession().save(user); commit(); close(); return
newuser; }

this code throws a ClassCastException: java.lang.Long I have mapped all
correctly, i have the same code that works perfectly in struts, but I
get that exception with struts2. Can anybody help me?

Re: [S2] ClassCastException on getParameters

2007-08-04 Thread Zarar Siddiqi

Why can't you access the HttpServletRequest object using
ServletActionContext.getRequest() and then just use the getParameter()
method to get the request parameters?

If you're getting a ClassCastException it's because you're casting
something that isn't a String to a String.  Find out what the type of
that object is and go from there.  It's simple debugging really.

RE: Tomcat 5.5.9 with Struts 1.2.7 - ClassCastException - looks like a Tomcat bug

2005-08-18 Thread stewart.cambridge


Thank you Christian - you are correct. A colleague also referred me to:
http://www.systemmobile.com/wp/?p=152 

I had a copy of jsp-api.jar in my app (/WEB-INF/lib/jsp-api.jar)
And Tomcat (both 5.0.28 and 5.5.9) has a copy under
$CATALINA_HOME/common/lib/jsp-api.jar

This makes the copy in my app redundant and it can safely be removed.
By removing it, it resolves the ClassCastException with
org.apache.struts.taglib.html.MessagesTei

But why should this double presence of jsp-api.jar be a problem for
Tomcat 5.5.9 but not for 5.0.28?

Thank you,

Stewart

Hi Stewart,

I had the same problem and I received a great answer on this mailing

a few days ago.

The problem is caused by either one of these libraries that are
conflicting with Struts: 
- jsp-api.jar
- jsp-2.0-api.jar

On my side, removing these libraries from my project (they were not
used)
solved the problem.

Through trial and error I have found that this does not happen with 
Tomcat 5.0.28, with all other factors (struts, my application, etc) 
kept the same. 

Thought you all might like to know.

ClassCastException

2005-07-25 Thread Nick Heudecker

I'm using Tomcat 5.5, JDK 1.5, Struts 1.2.7 and Tiles.  I'm getting
the following exception when I navigate to a Tiles page, I'm getting
the following:

java.lang.ClassCastException: org.apache.struts.taglib.tiles.UseAttributeTei

Anybody got an idea about what's causing this and a potential

It appears as though the problem is with your use of a form-property 
called page - based on what I am seeing around line 141 of the 
DynaValidatorForm code, if you have a property named page, it MUST be an 
integer, otherwise classcastexception is thrown.

I'm guessing this is to accomodate paged forms (aka wizards)
Try changing the property to have another name, and I think it will fix 
your problem.

Re: What Are the Causes For Validation to Throw ClassCastException?

2004-09-22 Thread Caroline Jen

I have changed the property from 'page' to 'pg'.  The
ClassCastException problem is gone.  However, the
validation.xml that I put in the AppName/WEB-INF is
not doing anything.

In my action mapping (struts-config.xml), I did set 

validate=true

and in my validation.xml, I have required set for
the depends attribute for every single text field.

depends=required

I intentionally left every field in those forms blank
and submit forms.  But, the Struts did not give me any
warning about that I leave text fields blank.

Re: What Are the Causes For Validation to Throw ClassCastException?

2004-09-22 Thread Matt Bathje

Do you also have /AppName/WEB-INF/validator-rules.xml?
Without that the validation won't work. Also make sure that you have the 
proper version of the validator jar.

Assuming those things are correct, take a look through your tomcat logs, 
I bet you are actually getting an error of some sort.

RE: What Are the Causes For Validation to Throw ClassCastException?

2004-09-22 Thread David G. Friedman

Jen,

DynaValidatorForm ALREADY has a page field so leave it out:

http://struts.apache.org/api/org/apache/struts/validator/DynaValidatorForm.h
tml

As for your validation not working with pg that's because the validator
uses the field name page to figure out which validations to test in
multi-page validations.

Additionally, WHY are you requiring a page field in your formset?  It should
be a hidden variable out of the view of the user so there is no need to
validate it.  Without it, the plugIn should assume page=0 and do the most
basic of validations in your formset.

Regards,
David

RE: ClassCastException when usig multiple web applications

2004-07-06 Thread McCormack, Chris

definition name=baseDef path=/am/WEB-INF/pages/mainLayout.jsp
put name=menuPanel value=/am/amMenupanel.jsp/

change your tile-defs to not include the context name of your application ie 

definition name=baseDef path=/WEB-INF/pages/mainLayout.jsp
put name=menuPanel value=/amMenupanel.jsp/

Also, why place your jsp's under WEB-INF ? Is there a security concern you are trying 
to overcome ? or were they just put there for no reason ?

Please paste in a sample action and a sample tile-def. The more info the easier it is 
to help you out. Also the name of your deployed app (context name).

Hi,

We have deployed a ROOT application and another application called 'AM' in Tomcat 
4.1.30. Both applications use struts. In struts config file as well as tiles 
definition files we have given all paths relative to context. Following exception is 
thrown, when action class is accessed.


java.lang.ClassCastException

struts ClassCastException

2004-05-19 Thread ksitron

My web-app runs great when first starting JBoss. After making src 
changes to my web-app, I build, and redeploy using ant. I then
attempt to test my changes by going down the exact same html:link 
navigation as before, only to receive a ClassCastException from 
org.apache.util.RequestUtils.createActionForm(RequestUtils.java: 777)

Any pointers would be greatly appreciated.

JDK 1.4.2

Re: Problem of ClassCastException when ArrayList to My own Class

2004-04-22 Thread JavaSoft

Check if your Array list.size in actionForm isnt 0.
And i suggest dont instantiate a new Array object in
Form bean becoz when your setter method failed for
some reason, when you do get you wont get any error
becoz you create an empty ArrayList and it will be
returned. Its better if you only declare or set it to
null, so you will get exception when it return null.

 Hi Friends,
 ThanQ very much 4ur non-stop help towards me.
 Here is a problem with Typecasting,throws
 ClassCastException.
 I'm not able get why it's getting.Bcoz i spent on
 this problem around 2weeks.
 i'm very thankful to u for ur solution.
  
 Problem of Area is as Follows:
  
 i've myown class called FileProperties
  
 Step:1
  
 public class FileProperties
 {
   private long fileSize;
   private Date fileDate;
   private String filename;
   private String filepath;
   private String clientid;
 ...some other
 properties..
 
   public FileProperties()
   {
   }
   public String getFilename()
   {
   return filename;
   }
   public void setFilename(String filename)
   {
   this.filename = filename;
   }
 
   public String getFilepath()
   {
   return filepath;
   }
   public void setFilepath(String filepath)
   {
this.filepath = filepath;
   }
 ...some other getter/setter
 methods.
 }
 
 Step:2
  
 In actionForm called mtActionForm i declared as
 follows:
  
 public class MtActionForm extends ActionForm
 {
 private FileProperties singleFile;
 private Collection mtJobsList=new ArrayList();
 ...some other
 properties..
 
   public Collection getMtJobsList() {
   return mtJobsList;
   }
   public void setMtJobsList(Collection mtJobsList) {
   this.mtJobsList = mtJobsList;
   }
   public FileProperties getSingleFile()
   {
 return singleFile;
   }
   public void setSingleFile(FileProperties
 singleFile)
   {
 this.singleFile = singleFile;
   }
 
  
 
 }
 Now i'm showing u exact problem of Area
  
 Step:3
  
 MtActionForm mtForm = (MtActionForm)actionForm;
 String tempStr =
 httpServletRequest.getParameter(fileIndex);
 int index = Integer.parseInt(tempStr);
 ArrayList aList =
 (ArrayList)mtForm.getMtJobsList();//No exception
 Here
  
 FileProperties sFile =(FileProperties
 )aList.get(index);//This is where 
 ClassCastException thrown
  
 mtForm.setSingleFile(sFile);
 
 Step:4
  
 In Jsp i'm going to use as follows
  
 bean:write name=mtActionForm
 property=singleFile.filename/
  
 I'm eagerly awaiting your reply as soon as possible.
  
 Thanks  Regards
 Ganesh
