RE: java.util.ConcurrentModificationException at org.apache.struts.action.ActionMessages.add(ActionMessages.java:185)

[Johan Kumps]

I think there is a thread on your backend writing to the ArrayList at the
same time your action class is reading the sam ArrayList instance.

I also had this problem and I fixed it by synchronizing the Arraylist during
the write(add) process.

synchronized (this.myArrayList) {
this.myArrayList.add(someElement);
}

Hope this helps.

Kind regards,

I am not using 2 threads, I was just saying than in
case of two threds being used, this Exception will be
thrown.  I can find whats the problem in my casei got
this:

 
   
 

 where colorSelected is a String with getter and
 setter in the orderEntry form bean, and colorOptions
is being returned by a getter in the same bean as an
 ArrayList.
 Something like this:

   public ArrayList getColorOptions() {
   colorOptions.add("red");
   colorOptions.add("green");
   return colorOptions;

Exception is being thrown when I am tryin to run it,
however if I return a String[] instead of ArrayList,
evetyhing works great.

Any ideas?

htm:checkbox default value

[Johan Kumps]

Hi all,

I would like to use a checkbox on one of my pages. Default it should be
checked.

Please consider following :

ActionForm :

...
private boolean addToMailingList = true;
...
public boolean isAddToMailingList() {
return addToMailingList;
}

public void setAddToMailingList(boolean addToMailingList) {
this.addToMailingList = addToMailingList;
}
...
public void reset (ActionMapping mapping, HttpServletRequest request){
this.addToMailingList = false;
}

Code above works fine but how can I specify the default value is checked.
Using the code above the default value is false.

Any ideas what I'm doing wrong?

Please help me as soon.

Kind regards,

Did you switch to ActionErrors.GLOBAL_KEY or change your JSP code?

1)  If you changed your JSP to  or
something, keep this in mind: I use a class called "Constants" for each web
app and refer to Constants.LOGINERROR_KEY in my code, but I have to make
sure that my JSP has the correct text.  What is the name of the property/key
you're assigning the error to?

2)  If you shifted to ActionErrors.GLOBAL_KEY, are you sure your locale is
right and your Resource bundle has the appropriate text key?

Try throwing this code in your JSP:


  
ERROR:  Language independent messages not loaded -- contact
administrator
for assistance.

Onderwerp: HELP! get request parameter from a custom tag


 Hi,

I apologize if this already was posted...I posted this earlier today, but
did not get see it posted...

If anyone can help me with this, it's stopping me from finishing key
portions of my applicaiton!

 I'm new to struts, and I am trying to retrieve a parameter that is in
 the request scope from a tag library.  Currently, I can print out the
 parameter on my jsp page using request.getParameter(name), but in my
 pageContext object in my tag library, I don't have the same list or
 request paramters, all I have are the Struts Form object, Bean object,
 and Error object.

 Somewhere Struts has overriden the default request object, and
 implemented it's own before my custom tag is called.  Would someone
 please tell me how I can retrieve the JSP page's request attributes in my
custom tag?

 Thanks in advance,

 Kevin Williams

You override the reset method to set unchecked value.

1. You know how many elements in your array, so instantiates your array.
2. You know the unchecked value of each element, so do a loop and set
default value to each element.

I do not have a default value. The user can choose between two options. He
can select both checkboxes, one of both or none.

What is going wrong?

...
private String[] myHandlers = {};
...
public void setMyHandlers (String[] myHandlers) {
this.myHandlers = myHandlers;
}

public String[] getMyHandlers() {
return this.myHandlers;
}
...

Am I doing somthis wrong here?

Please help me with this one.

Kind regards,
Johan

Many thanks in advance,

Are you using beta3 of struts1.1? If so you could use declarative
exception handling in your config.xml just like you would for any other
action. It works perfectly. Let me know if you have any more questions.

Are you using beta3 of struts1.1? If so you could use declarative

DispatchAction error handling how to?

[Johan Kumps]

Hi all,

Can somebody please trow a light on error handling using a  DispatchAction.
The class org.apache.struts.actions.DispatchAction in Struts  1.1b2 is
catching an InvocationTargetException. So when the 'dispatchMethod' invokes
a method that throws an exception, it's catched here.

How can I do some specific error handling? I don't want to code any catches
in my action classes. How can I catch an exception in my DispatchAction?

Why is org.apache.struts.actions.DispatchAction catching an
InvocationTargetException?

Kind regards,

Exception handling - DispatchAction

[Johan Kumps]

Hi all,

I have following problem.

In my Action class I'm calling a bussiness method that can throws a checked
exception. I want to display this exception to the user on a user friendly
page without the stacktrace. Because I have many action classes I don't want
to code try catch blocks in all these action classes to catch the checked
exception. I'm using a dispatch action so I can code several bussiness
actions in one action class.

Any ideas to solve my problem?

Kind regards,

Johan
