Re: validation, input page, and request-scoped variables
Thanks for the reply. So in your save action your form input is the action that sets up the form. Meaning that in your struts-config for the save action you have input=/edit.do or input=/add.do...? Which one do you choose? Also, as I understand it, this can only work if the action doesn't set any of the form fields. Do your actions set any form fields? If not, then I guess you can always use the add action. But in my case the add action sets some values (for example to preselect a default item in an options list), and of course the edit action also sets values (it looks up the values from the database). So after submitting, if the validation fails, the form field values are changed, they are not what the user just typed. Or am I misunderstanding something? Thanks...

Two possible solutions: 1.

If I do it this way I will need two save actions, one that uses the edit page as the input and one that uses the add page as the input.

Re: How to dynamically decide the properties of the DynaValidator/DynaActionForm
Concerning the validation, what you do depends on whether all the possible different validation mechanisms are limited to a defined set, or whether it is an unbounded set that you cannot limit at design time.

Re: validation, input page, and request-scoped variables
Ah, I see I missed out a bit of the logic. My action class has a part that is executed for every action mapping, which fetches the necessary related data, such as dropdown lists (but not the actual object's properties). What else the action does is dependent on the result of a bit of logic which is executed after the mandatory processing mentioned above. I'm having problems describing it, perhaps it's easier to understand just looking at the xml: actionpath=/secure/startSectionInsert type=org.blacksail.linklib.section.SectionAction name=sectionForm scope=request validate=false parameter=blank roles=user set-property property=secure value=false/ forward name=finished path=.section/ /action actionpath=/secure/startSectionUpdate type=org.blacksail.linklib.section.SectionAction name=sectionForm scope=request validate=false parameter=display roles=user set-property property=secure value=false/ forward name=finished path=.section/ /action actionpath=/secure/sectionUpdate type=org.blacksail.linklib.section.SectionAction name=sectionForm scope=request validate=true parameter=save input=/secure/sectionValidateFailed.do roles=user set-property property=secure value=false/ forward name=failed path=.section/ forward name=displaypath=/secure/startSectionUpdate.do/ forward name=finished path=/secure/library.do redirect=true/ /action actionpath=/secure/sectionValidateFailed type=org.blacksail.linklib.section.SectionAction name=sectionForm scope=request parameter=finished roles=user set-property property=secure value=false/ forward name=finished path=.section/ /action Both insert and update submit to update. The last mapping there just does the mandatory getting the required dropdown lists. HTH Adam On 08/24/2003 02:13 AM ll wrote: Thanks for the reply.

Re: How to dynamically decide the properties of the DynaValidator/DynaActionForm
Okay .. I've been thinking about this.
I think it might work something like this..
form-property name=beans property=java.util.ArrayList /
The arrayList will be a container for your beans with indexed
properties.
So in jsp we're thinking, or aiming for
logic:iterate id=bean name=myForm property=beans
bean:write name=bean property=key[%= index %] /
html:text name=bean property=value[%= index %] /
/logic:iterate
So we have a bean thats mapped backed, or something here's some pseudo
code.
public class MyBean {
private Map map;
public Object[] getKeys() {
return map.keySet().toArray();
}
public Object[] getValues() {
ArrayList list = new ArrayList();
Object[] keys = getKeys();
for(int i = 0;i keys.length;i++) {
String value = map.get(keys[i].toString());
list.add(value);
}
return list.toArray();
}
public String getKey(int i) {
return keys[i].toString();
}
public String getValue(int i) {
String key = getKey(i);
return map.get(key);
}
public void setKey(int i, String str) {
keys[i] = str;
}
public void setValue(int i , String str) {
map.put(getKey(i),str);
}
...
well you get the idea..
Am I tree barking, smoking crack or something but Its starting look
possible.. el should help move the scriptlets out, but using indexed,
mapped properties looks like it may do the job.. the bean could have a
double sided array it returns to keep the keys and values in the
correct order. The keys are after all the illusion that the properties
have names, when really they are associated via index. When it comes
time to write to a db or something the bean could return a map and the
key=value pairs should all be there ready.

Design question...
I have a JSP page that contains entries from a database. I am getting the items using a DTO that is passed from a session EJB. What I would like to be able to do is to specify a parameter in the URL named offset that when changed would display the next results from the database. Couple of questions... Would it be considered presentation logic to perform the action of getting the DTO from the session bean within the JSP page? I really don't want to do it that way because I'm trying to keep the layers as separate as possible. So, if I don't do it that way, I will have to use Action classes and html:links that can pass the parameter to action class? My real question is what is the best way of dealing with EJBs in the presentation layer? I know that I have to get a DTO of the information that I want, but usually the methods of the DTO take parameters that I can't pass to the DTO in the JSP page.

DynaForm Beans and Indexed Text fields.
I'm having a problem using Indexed text fields with DynaActionForms. I can make a jsp display my indexed text fields just fine using the logic:iterate and html:text custom tags. The problem is when I submit the form, there is a problem populating the DynaActionForm with my indexed text values. I'm wondering if the problem is the fact that the collection used is a java.util.List populated with by own custom beans, each bean containing three String fields with their own getters/setters. I'm wondering if I can use DynaActionForms in this instance. Below is a copy of my DynaActionForms Config, the jsp code that utilizes the form and the error message I get when the form is submitted. Any input would be of great help. Thanks, Joel. Here's my DynaActionForm Bean declaration in struts-config.xml: form-bean name=persistRateInfo type=org.apache.struts.action.DynaActionForm !-- Specify the dynamic properties of the form -- form-property name=hazardInsRate type=java.lang.String/ form-property name=dealOneTerm type=java.lang.String/ form-property name=dealOneIR type=java.lang.String/ form-property name=dealOnePercentageDown type=java.lang.String/ form-property name=dealTwoTerm type=java.lang.String/ form-property name=dealTwoIR type=java.lang.String/ form-property name=dealTwoPercentageDown type=java.lang.String/ form-property name=dealThreeTerm type=java.lang.String/ form-property name=dealThreeIR type=java.lang.String/ form-property name=dealThreePercentageDown type=java.lang.String/ form-property name=pmiRanges type=java.util.List/ /form-bean Here's the loop I use in the jsp that needs to display the values of pmiRanges. of the form bean: logic:iterate id=pmiRanges name=persistRateInfo property=pmiRanges tr td style=font-family: sans; font-size: 12; width=100Low: /td td style=font-family: sans; font-size: 12; html:text name=pmiRanges property=low indexed=true size=5/ /td td style=font-family: sans; font-size: 12; width=100High: /td td style=font-family: sans; font-size: 12; html:text name=pmiRanges property=high indexed=true size=5/ /td td style=font-family: sans; font-size: 12; width=100Rate: /td td style=font-family: sans; font-size: 12; html:text name=pmiRanges property=rate indexed=true size=5/ /td /tr /logic:iterate Now I use a Struts Action to preload this form bean with values from a database. It does this fine. When the jsp is called for the first time, it utilizes the form bean, and the List perfectly and displays the indexed text fields just like I want it to. here is an example row of rendered text fields: tr td style=font-family: sans; font-size: 12; width=100Low: /td td style=font-family: sans; font-size: 12; input type=text name=pmiRanges[0].low size=5 value=10.0 /td td style=font-family: sans; font-size: 12; width=100High: /td td style=font-family: sans; font-size: 12; input type=text name=pmiRanges[0].high size=5 value=15.0 /td td style=font-family: sans; font-size: 12; width=100Rate: /td td style=font-family: sans; font-size: 12; input type=text name=pmiRanges[0].rate size=5 value=5.7 /td /tr The problem comes in when I try to submit the form to save the form values. It doesn't seem that the form bean can be populated with the indexed values. I get the follwoing Exception: ? java.lang.NullPointerException: No indexed value for 'pmiRanges[0]' at org.apache.struts.action.DynaActionForm.get(DynaActionForm.java:293) at org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUtils.java:474) at org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyUtils.java:428) at org.apache.commons.beanutils.PropertyUtils.getNestedProperty(PropertyUtils.java:770) at org.apache.commons.beanutils.PropertyUtils.getProperty(PropertyUtils.java:801) at org.apache.commons.beanutils.BeanUtils.setProperty(BeanUtils.java:881) at org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:808) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: DynaForm Beans and Indexed Text fields.
In the StrutsAction I use to preload the form? yep If you specify name attribute for your action mapping struts will create form bean upon request to your action. So whatever action causes your bean to be instantiated would need scope attribute to be set to session. action path=/yourAction type=your.action.class name=yourFormName scope=session Alex. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Here's my DynaActionForm Bean declaration in struts-config.xml: form-bean name=persistRateInfo type=org.apache.struts.action.DynaActionForm !-- Specify the dynamic properties of the form -- form-property name=hazardInsRate type=java.lang.String/ form-property name=dealOneTerm type=java.lang.String/ form-property name=dealOneIR type=java.lang.String/ form-property name=dealOnePercentageDown type=java.lang.String/ form-property name=dealTwoTerm type=java.lang.String/ form-property name=dealTwoIR type=java.lang.String/ form-property name=dealTwoPercentageDown type=java.lang.String/ form-property name=dealThreeTerm type=java.lang.String/ form-property name=dealThreeIR type=java.lang.String/ form-property name=dealThreePercentageDown type=java.lang.String/ form-property name=pmiRanges type=java.util.List/ /form-bean Here's the loop I use in the jsp that needs to display the values of pmiRanges. of the form bean: logic:iterate id=pmiRanges name=persistRateInfo property=pmiRanges tr td style=font-family: sans; font-size: 12; width=100Low: /td td style=font-family: sans; font-size: 12; html:text name=pmiRanges property=low indexed=true size=5/ /td td style=font-family: sans; font-size: 12; width=100High: /td td style=font-family: sans; font-size: 12; html:text name=pmiRanges property=high indexed=true size=5/ /td td style=font-family: sans; font-size: 12; width=100Rate: /td td style=font-family: sans; font-size: 12; html:text name=pmiRanges property=rate indexed=true size=5/ /td /tr /logic:iterate Now I use a Struts Action to preload this form bean with values from a database. It does this fine. When the jsp is called for the first time, it utilizes the form bean, and the List perfectly and displays the indexed text fields just like I want it to. here is an example row of rendered text fields: tr td style=font-family: sans; font-size: 12; width=100Low: /td td style=font-family: sans; font-size: 12; input type=text name=pmiRanges[0].low size=5 value=10.0 /td td style=font-family: sans; font-size: 12; width=100High: /td td style=font-family: sans; font-size: 12; input type=text name=pmiRanges[0].high size=5 value=15.0 /td td style=font-family: sans; font-size: 12; width=100Rate: /td td style=font-family: sans; font-size: 12; input type=text name=pmiRanges[0].rate size=5 value=5.7 /td /tr The problem comes in when I try to submit the form to save the form values. It doesn't seem that the form bean can be populated with the indexed values. I get the follwoing Exception: ? java.lang.NullPointerException: No indexed value for 'pmiRanges[0]' at org.apache.struts.action.DynaActionForm.get(DynaActionForm.java:293) at org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyU tils.java:474) at org.apache.commons.beanutils.PropertyUtils.getIndexedProperty(PropertyU tils.java:428) at org.apache.commons.beanutils.PropertyUtils.getNestedProperty(PropertyUt ils.java:770) at org.apache.commons.beanutils.PropertyUtils.getProperty(PropertyUtils.ja va:801) at org.apache.commons.beanutils.BeanUtils.setProperty(BeanUtils.java:881) at org.apache.commons.beanutils.BeanUtils.populate(BeanUtils.java:808) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Java Question
I've been trying to compile my BLB (Business Logic Bean) and have been getting errors during compilation. I haven't a clue as to how I could debug this. Any assistance would be appreciated. ResultSet rs = stmt.executeQuery(SELECT FACIL_ID, FACIL_NAME, FACIL_NAME_SHORT, ORG_ID FROM FACILITY WHERE FACIL_ID = ' + facilId + '); Change that line to: rs = stmt.executeQuery(SELECT FACIL_ID, FACIL_NAME, FACIL_NAME_SHORT, ORG_ID FROM FACILITY WHERE FACIL_ID = ' + facilId + '); You can not redeclare a variable in the same scope. The way you were trying to do it was have two variables called rs in the same scope, the ammendment, simply replaces one resultset with another, for the object reference - rs. -- Mike W - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
JSR 168 conflict with Struts?
I apologize if anyone has already asked this question, but I searched the board and didnt see it. JSR 168 has the following line in it (Section PLT.16.3): Servlets and JSPs included from portlets should not use the servlet RequestDispatcher forward method as its behavior may be non-deterministic. I am no expert on Struts, although I have used it quite a bit. It seems that if I wanted to wrap my Struts app in a Portlet and access various actions through the PortletRequestDispatcher (the most logical approach), I would run afoul of this warning. Lacking an implementation to test my hypothesis (*$# IBM legal department), I am unsure whether this actually fails or not. My gut instinct is that it probably wouldnt, but that it may not be reliable across implementations of servlet and portlet containers. I wanted to get some thoughts from the Struts community about this possible issue. Also, I wanted to know what the impact would be of using RequestDispatchers include method instead? Or at least providing the facility to portlet developers? I apologize if I have wrongly assumed anything in my question. This is my best estimate based on what I have read. Thanks, Clay Richardson W.
