Error handling (ServletException)
Is there something special I have to do to handle a ServletException? No matter what I try, the stack trace always seems to be sent to the standard Tomcat error page. I've tried configuring global-exceptions in struts-config, but that doesn't seem to work. What's the secret? global-exceptions exception handler=org.apache.struts.action.ExceptionHandler key=global.error.message path=/error scope=request type=javax.servlet.ServletException / /global-exceptions javax.servlet.ServletException: BeanUtils.populate at org.apache.struts.util.RequestUtils.populate(RequestUtils.java:980) at org.apache.struts.action.RequestProcessor.processPopulate(RequestProcess or.java:779) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java: 246) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1292) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:510) Thanks!

I don't think this will trump any of the fine examples posted so far, but I have always found this gsu error message amusing: gsu: you won't be doing that today.

Re: Error handling (ServletException)
Your action throws an Exception which got rethrow as ServletException by the controller if the original exception is not caught by your handler. So you need to change your configuration to catch Exception ( or whatever the real one is) not ServletException. Hope this helps. -D - Original Message - From: Pete Gieser [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Sunday, December 15, 2002 12:54 AM Subject: Error handling (ServletException) Is there something special I have to do to handle a ServletException?

html:select question
Howdy folks,
I am having some problems and hope somebody can help. Using
struts-example as a starting point, I would like to move the following
decalration out of the jsp page and into the ActionBean(for the sake of
this example, we add it there):
java.util.ArrayList list = new java.util.ArrayList();
list.add(new example.LabelValueBean(one, 1));
list.add(new example.LabelValueBean(two, 2));
list.add(new example.LabelValueBean(three, 3));
list.add(new example.LabelValueBean(four, 4));
so in my FormBean and DataBean I added the setter and getter methods to
accomodate the above declaration eg:
private ArrayList list = null;
private String select = one;
public void ArrayList getList(){
return list;
}
public void setList(ArrayList list){
this.list=list;
}
public void String getSelect(){
return select;
}
public void setSelect(String select){
this.select=select;
}
and added the list to the DataBean(which is used to populate the
FormBean) in the ActionBean:
...
data.setList(list);
...
now for the problem, how should i define the html:select and
html:options tags to get it to display the ArrayList instantiated in
the ActionBean?
html:select property=select
html:options collection=list
property=value
labelProperty=label/
/html:select
but this does not work.
Any help will be greatly appreciated.
Thanks
William

Re: html:select question
Figured it out, I needed to add:
session.setAttribute(list, list);
To my ActionBean

RE: Move to TilesRequestProcessor results in forwarding exception.
If I specify a Tiles definition file I must supply at least one definition. Otherwise I get this: org.xml.sax.SAXParseException: The content of element type tiles-definitions is incomplete, it must match (definition)+. So my Tiles definition file looks like: tiles-definitions definition name=dummy path=/layouts/dummyLayout.jsp/ /tiles-definitions The file layouts/dummyLayout.jsp does not actually exist. However I seem to get no errors at runtime. So I think I've got the right configuration now to proceed with a refactoring toward Tiles.

logic:iterate
Hi: Have you used pager tag library from http://jsptags.com/tags/navigation/pager/ with logic:iterate tag? I am using them together, and I have a problem. Please help me if you know what's going on in the following problem. I really appreciate your help.(Rick suggested me to use display tag from http://edhill.its.uiowa.edu/display-0.8/. I had a look. And it's excellent. However, the project is almost in production phase, I prefer to fix the problem based on what I have now instead of changing the implementation. Thank Rick, anyway). I retrieved 23 rows from Database, and I saved the data in session. I want to display the data on 10 rows/page basis with page navigation ability.So on the first page, there are 10 rows and a next link, On the second page, there are 10 rows and previous and next link. On the third page, there are 3 rows and a previous link. I used logic:iterate to iterate through the data, and use pager tag library from the above link to implement the page navigation ability.The following is my jsp snippets: %@ taglib uri=/WEB-INF/pager-taglib.tld prefix=pg % .. pg:pager maxPageItems=10 isOffset = true logic:iterate id=aResult name=results scope=session type=com.test.Result pg:item tr td bean:write name=aResult property=note/ /td logic:notEqual name=aResult property=amount value=0 td bean:message key=amount.value//font/div /td /logic:equal /tr /pg:item /logic:iterate -- page navigation area-- /pg:pager Page navigation works fine(I mean when I click next or previous, it goes to next or previous page. So I omitted the page navigation snippest. The problem is: when the first page is displayed, I viewed the source of the first page, there are 10 blank rows before the line -- page navigation area-- -- I mean there is a big spaces which is equal to 10 rows, between the last row and the line -- page navigation area--. After I click next link and opened the second page, I viewed the source, I found between the last row on the page and the line -- page navigation area--, there are 3 blank rows(because the next page has 3 rows). When I opened the third page(last page), and viewed source, there is no blank row(because there is no next page). In order to solve the problem, I searched the archive and the web. I found lot of disussion about paging. But there seems no discussion about the blank rows problem. Could you help me out here. I spend a lot of time trying to fix it, but no clue. I really appreciate your help. Thank you very much. Cathy
Iterate tag Tomcat 4.1.12, issue or no?
After much scanning of the user-list archive I have seen some mentions of a problem with tomcat 4.1 and the logic:iterate tag. I have also seen mentions of Tomcat 4.1.12 working fine with the logic tag. Does a problem exist? I am getting the following error, my code matches the example code in the logic taglib guide, so I am out of ideas on what is wrong. ERROR: cannot resolve symbol symbol : variable myMessage Code in JSP: % SessionUtility su = new SessionUtility(); ArrayList messages = (ArrayList) su.getAttribute(session, HomeConstants.MESSAGE_ARRAY); % table TR TD !-- Begin Display of Messages -- %= messages.size() % logic:iterate id=myMessage collection=%=messages% %= myMessage.getSubject() % /logic:iterate If I remove the logic tag completely the messages.size() tells me that I have two Objects in the array list, so I know the information is in there I just can't get to it. I have also tried this with the type=com.mysystem.bo.bean.Message set as well, still It does not work. Any Ideas? Thank you for your help, Mark

That's actually simple ... the logic:iterate tag does not create a scripting variable. It only stores the current element you are iterating over in the attribute defined by name. Scripting variables are only needed if you're going to use scriptlets or runtime expressions, and in general that (especially scriptlets) is discouraged. NOTE: When you start using JSTL, you'll find that the iteration tags in that library act the same way.

RE: [OT] Overloaded setters in JavaBeans
I looked all over for an example. I read the docs and even tried to
create an example, but I can not get this to work. I created a BeanInfo
and defined my MethodDescriptors, here is the code:
public MethodDescriptor[] getMethodDescriptors()
{
MethodDescriptor rv[] = null;
try
{
Method setEmailString = beanClass.getMethod(setEmail, new Class[]
{String.class} );
Method setEmailForm = beanClass.getMethod(setEmail, new Class[]
{EmailForm.class} );
Method getEmail = beanClass.getMethod(getEmail, new Class[] {});
Method setName = beanClass.getMethod(setName, new Class[]
{String.class});
Method getName = beanClass.getMethod(getName, new Class[] {});
Method[] methods = new Method[] { setEmailString, setEmailForm,
getEmail, setName, getName };
rv = new MethodDescriptor[methods.length];
for(int i=0;imethods.length; i++)
{
rv[i] = new MethodDescriptor(methods[i]);
}
}
catch (NoSuchMethodException e)
{
e.printStackTrace();
}
return rv;
}
This is all that is in my BeanInfo. The Form only has two properties:
String name, EmailForm email. The email property has two setters, one
for EmailForm and one for String. I still get the
IllegalArgumentException: argument type mismatch. Would someone please
fill in the blanks? What am I missing here?

Subject: [OT] Overloaded setters in JavaBeans
It is now a well-known fact on this list that if you are trying to
access a property using a tag you had better not have an overloaded
setter for this property. In other words don't do
private String foo;
public String getFoo() { return foo; }
public void setFoo(String x) { foo = x; }
public void setFoo(int i) { foo = + x; }
Equally well-known is the reason -- 'tis the JavaBeans
specification. So, I went looking. Section 7.1 (Accessor methods)
reads
Begin quote ---
Properties are always accessed via method calls on their owning
object. For readable properties there will be a getter method to read
the property value. For writable properties there will be a setter
method to allow the property value to be updated.
--- End quote
Section 8.3 (Design Patterns for Properties) reads
Begin quote ---
By default, we use design patterns to locate properties by looking for
methods of the form:
public PropertyType getPropertyName();
public void setPropertyName(PropertyType a);
If we discover a matching pair of getPropertyName and
setPropertyName methods that take and return the same type, then
we regard these methods as defining a read-write property whose name
will be propertyName. ...
If we find only one of these methods, then we regard it as defining
either a read-only or a writeonly property called propertyName
--- End quote
It doesn't say anything about not overloading the accessors. So, why
then do we get the error?
The implementation of java.beans.Introspector (which is what BeanUtils
uses under the covers) has always interpreted the discover a matching
pair restriction to mean discover a matching pair and ONLY the
matching pair; i.e. no other methods by the same name.
Note that you can actually use overloaded setters if you want to, but
you're going to have to go to a fair amount of effort. Essentially,
you'd need to provide a BeanInfo class for each of your beans that
declared what the actual Method implementations of the getter and setter
are for each property.

Struts-config.xml
Hi I am new to the Struts, testing some sample applications. we want to implement the struts in our existing project. right now we have almost 50 tables and more than 200 submittion pages. what my concern about the struts is if i have to configure all the form beans and the action mappings the struts-config.xml will become large file. is there any way i can create new configuration file and the action servlet class referes to this config.xml. what i mean is can i divide into different config files. Thanks usha -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Forward to a servlet
Hi folks, In my Struts app, I am using the Action to call the jsp file. In the struts-config.xml, the action tag looks like this, action path=/accounts type=com.mydomain.AccountsAction name=accountsForm validate=false input=/WEB-INF/jsp/AccountsHTML.jsp forward name=accounts path=/WEB-INF/jsp/AccountsHTML.jsp/ /action Because of some deployment issue, I need to pre-compile the jsp files. I successfully use the ANT's jspc tag to compile the all the jsp files to java files, then compile them to java files. However, I cannot make it use the servlet in the forward tag. I tried to do this (AccountsHTML_jsp is class file of the compiled version of AccountsHTML.jsp), but I get 404 page. action path=/accounts type=com.mydomain.AccountsAction name=accountsForm validate=false input=/WEB-INF/jsp/AccountsHTML.jsp forward name=accounts path=/WEB-INF/ui/AccountsHTML_jsp/ /action Would anybody knows how can I make this work? Thanks in advance! Billy Ng
RE: Forward to a servlet
I thought that even with precompiling you would just point the forward at the .jsp file as normal?

Re: Forward to a servlet
Interesting! Tell me if I am wrongly interpret your message. Do you mean I should deploy the precompiled jsp files to tomcat/work/standalone/localhost/myApp ? If not, how does the servlet container, tomcat, know I have already precompiled the jsp files when the forward tag points to the jsp files?
