Subject: Checkboxes and Intermittent BeanUtils.populate Error
Comrades,
I check a checkbox and submit, I get the error. If I do not use the checkbox
and hit submit, the page comes up successfully. Any issues with primitives
in relation to the FormBean member population?
The strange thing is that this problem does not occur all the time. The page
prior to this JSP has a form with checkboxes and that works fine with
checkboxes checked. That is creepy and worries me.
I looked at the source code and here is a snippet from
BeanUtils.setProperty(Object, String)
//
else { // Value into scalar
if (value instanceof String || (value == null
type.isPrimitive())) {
newValue = ConvertUtils.convert((String) value, type);
} else if (value instanceof String[]) {
newValue = ConvertUtils.convert(((String[]) value)[0],
type);
} else {
newValue = value;
}
}
//
I wonder if this part is messing things up for primitive types. I checked
the checkBox Value and it got the String as on.
Now the code that takes this on and sets the ValueObject boolean variable
to true seems to be causing the problem.
My getters for boolean are getFoo() and setFoo() where foo is a boolean.
Should it be setFoo() and isFoo()??
Please Advise

Re: Wrapping Collections in LazyList to auto-populate form on Submit
Arron,
Thanks for responding.
Things seem to be clearer now. I have a question to ask though.
We all know Bananas have seeds. (So a BananaBean can have a collection of
seeds.)
Now I have a situation where I have to set the property of the seed bean via
the JSP on submit.
Lets have a seed bean
public class SeedBean {
public String getColor() { return color; }
public void setColor(String str) { color= str; }
private String color;
}
Now in the MonkeyBean (Which is the formbean ) can I say the following?
public class MonkeyBean {
public List getBananas() { return bananas; }
private List bananas = LazyCollections.lazyList(new
ArrayList(LazyCollections.lazyList(new ArrayList(), SeedBean.class)),
BananaBean.class);
}
I tried doing the same but it didnt work :(
Thanks for your time

Hemant,
Sorry about the issues you're having, but at face value it seems that
you're almost trying too hard. Without seeing the rest of your code,
it's hard to see what your generateWrappedCollection() method is trying
to acheive, so I'll try to answer with code...
With the collection wrapping, it's a simple one liner in the bean. For
example, in all my monkey examples, they all return the collection as
the indexed property type (because it's a valid indexed getter and the
iterate tags can use the collection to get their thing going). All you
need to do is wrap that collection directly.
For example, two complete beans...
public class MonkeyBean {
public List getBananas() { return bananas; }
private List bananas = LazyCollections.lazyList(new ArrayList(),
BananaBean.class);
}
public class BananaBean {
public String getFlavour() { return flav; }
public void setFlavour(String str) { flav = str; }
private String flav;
}
The MonkeyBean is the parent class that hold the collection. It has
immediately wrapped the ArrayList in the LazyCollection, and passed it
the class of the BananaBean object. You may want to keep a reference to
the wrapped ArrayList, generally I don't have the need to.
These classes are all but ready to rock. In the action class, query the
database or whatever and populate the MonkeyBean with the BananaBean
data. Serve the result to the JSP.
JSP write out a list of text boxes using iterate tags. Submit this, and
after the monkeybean is built, the lazy collection will grow the banana
list with banana beans as the indexed requests come in.
When it gets back to your action class, you'll have your collection of
banana beans.
Hope this helps, you know where we are if it doesn't.
Arron.

The seed beans would be child beans to the banana beans. You'd ask the
monkey bean for the collection of bananas, and once you have a banana,
you'd ask the banana for the list of it's seeds. So, the list becomes a
member of the banana. Looking a little like this...
public class BananaBean {
public String getFlavour() { return flav; }
public void setFlavour(String str) { flav = str; }
public List getSeeds() { return seedList; }
private List seedList = LazyCollections.lazyList(new ArrayList(),
SeedBean.class);
private String flav;
}
Nested beans are all about composition. Each nesting level will be
composed of that beneath it. Monkey's don't manage seeds, they manage
bananas. Seed management is up to the Banana. If there's another level,
then the seed bean will take care of that. The Monkey examples of my
site are an example of all this. What may be confusing is that they
build objects and at times their children for sake of convenience. But
the member collections themselves are always attached to the object
they're concerned with.
So when the request comes in, it will make the monkey object for the
form. It'll then ask for the banana at the index. When the banana's made
it will make the lazy wrapped list of seeds. so when an update for a
seed comes in, then it will make the seed object for the banana.
Once you have one level going, the rest are just as easy. From one to a
hundred list levels, it's all the same. Other things come to light
too... you don't have to always have the model start with monkey. Say
another form which is banana specific, you can use the same banana
object in another model, and it'll work just as well. Gotta love OOP :)

To answer your second question, the LazyCollections aren't yet public
(unless I am in some kinda coma) , they can be found in commons nightly
builds.This is OO Software Craftsmanship at its best!! The code is very
well documented and should be enough to get you going.

Two questions:
1 - In our situation we will be getting a *result* object with an
internal list from the backend that is similar to the MonkeyBean.
I would NOT be able to change it's implementation (ie:adding
LazyCollections) . How could I achieve the same thing? Would I need to
create to temporary list wrappers that would be used to manually insert
the newly created lists ?
2 - Are the LazyCollections public now. The last I heard they were
on
there way to Commons. I have been checking Arrons site and have seen to
mention
of them. I also understand that some of the tutorials will be updated
with
the lazy collections instead of putting the list in session. Is this the
case?

Upon reading your reply, i modified my MonkeyBean and BananaBean to have a
wrapped BananaBean List and wrapped SeedBean List respectively.
I fire up the page and submit, and check for the changes in the BananaBean
List in MonkeyBean but the change in seed information does not seem to be
updated in the banana list upon submit.
Any bonehead thing that I might have done?

collections of ValueObjects. Each valueObject contains a pair of other Value Objects.

2 It is not a case of bean being in request scope. By default the bean is in session
scope (Unless we explicitly mention the action attribute that it is request scope.)
When asked about why the nested beans were not dynamically populated even though the
getter() methods are beling called, Nesting and Recursion Guru Arron Bates said the
following:
quote
FYI
This isn't a nested tags issue at all, but a nested bean-in-a-list
issue which Struts had a long time before I wrote the nested tags.
They're only guilty of making something quite complex very easy to do.
:)
Wrap your collections in org.apache.commons.collections.LazyList,
provide a class definition of your child bean and it'll be sweet and
ready to do without any other effort, even in the reset() method.

So without wasting anytime, I downloaded the nightly build and incorporated it into my
IDE. I still seem to be missing something.

property=this/ VS property=something in nested:iterate
Here is a snippet from my JSP
//Start of Snippet///
nested:iterate id=collectionOfRanges property=collectionOfRanges
nested:iterate id=vopair property=this/
type=com.xxx.operations.mplanning.mpi.util.ValueObjectPair
nested:root name=vopair
.
...
td
nested:write name=vopair property=twVo.objectType/ - nested:write
name=vopair property=twVo.description/
/td
//End of Snippet///
Now the getters work fine. The setters for some reason do not work. Yes, I
have my reset() method and it is as follows
public void reset(ActionMapping mapping, HttpServletRequest request)
{
if (this.collectionOfRanges == null)
{
HttpSession session = request.getSession();
MpiServiceBean msb =
(MpiServiceBean)
session.getAttribute(MpiConstants.MPI_SERVICE_BEAN);
this.collectionOfRanges = msb.getRanges();
}
}
So the collectionOfRanges is populated before the page is fired up and it
is expected that this method is called before Submit data is fed into
collectionOfRanges .
But for some reason, the setter() methods are not being called.
Is this because of having
nested:iterate id=vopair property=this/
type=com.xxx.operations.mplanning.mpi.util.ValueObjectPair
instead of
nested:iterate id=vopair property=something
type=com.xxx.operations.mplanning.mpi.util.ValueObjectPair
???
If that is true, then it would mean I need a bean for every property that I
want to set. Isnt that cumbersome?
Thanks in Advance

Adam
Thanks for responding..
The Actionform (rangesform) itself is my root and I have a collection
reference collectionOfPairs in rangesform, replete with getter/setter
methods.
The collectionOfPairs is instantiated and populated. If not, I would not
be
seeing the page with the correct data. right?
As I said earlier, the getters work, the setters do not work. All this
inspite of having the bean in the form.

nested tags / indexed properties / nested beans gotcha. You have to
instantiate the beans yourself in the form reset() if you want to
capture the indexed properties.

I set up a debug point at the beginning of validate() method. For some reason, the
execution fails even before it gets to that point. Instead I get the following
exception. Could someone please throw some light on this? Iam not really sure where
exactly the problem lies.

Action Form Dictating Value Objects?
Comrades,
Let us take the check the fruit example posted by Larry Maturo. Here the Fruit Object
needs to have a boolean value called checked.
The ValueObject makes sense when its in a Struts Environment but doesnt it look like
we have compromised on the Value Object definition? the checked instance variable
should not have been there in the first place as it has nothing to do with a Fruit
abstraction. I guess we need something like a ValueObject add on object to plug it
in when we use this Object in a Struts environment.
later
hemant
//start

Subject: Action Form Dictating Value Objects?
Comrades,
Let us take the check the fruit example posted by Larry Maturo. Here the Fruit
Object needs to have a boolean value called checked.
The ValueObject makes sense when its in a Struts Environment but doesnt it look like
we have compromised on the Value Object definition? the checked instance variable
should not have been there in the first place as it has nothing to do with a Fruit
abstraction. I guess we need something like a ValueObject add on object to plug it
in when we use this Object in a Struts environment.

Re: Newbie: pass ResultSet to JSP?
The cached Row set works extremely well for small volumes but when volumes are large, its can cause a resource problem as these objects hog the memory especially when there are a large number of users. just a thought. later hemant - Original Message - From: Shekhar Jain [EMAIL PROTECTED] To: 'Struts Users Mailing List' [EMAIL PROTECTED] Sent: Friday, June 21, 2002 1:06 PM Subject: RE: Newbie: pass ResultSet to JSP?

Options Tag, Property Attribute and Accessor Consumption.
Comrades, Here is a Scenario. Let us say we have 2 kinds of value objects extending a base ValueObject. AVo and BVo extend BaseVo and BaseVo has a method getKey() Now I have a collection of AVo's and another collection of BVo's. I want to provide the descriptions of these VO's in a dropdown and capture the key during the process. Both the dropdowns exist in the same form. so the code would be something like. html:select property=key name = ldmGroup indexed=yes html:options collection=ldmGroups property=key labelProperty=formattedDescription/ /html:select So, that takes care of AVo collection in a dropdown. html:select property=key name = twGroup indexed=yes html:options collection=twGroups property=key labelProperty=formattedDescription/ /html:select This is what I have to do to capture BVo's keys. Now I also want to have a drop down of BVo collection but the key[] in formbean is already filled by AVo collection parameters. How can I use the dropdown and capture the BVo's keys? Thanks for your time. hemant
On a Tangent, Connection Pooling for UDB/400
Good Morning Comrades Pardon me for posting this post on a Struts group. This message is on a tangent as it discusses connection pooling and connections to UDB/400. I simply cound not resist it, I definitely know there are a quite a few of us who have faced this problem hence, requesting them for advise. I have a connection pool with connections to UDB/400 and I am using a class4 JDBC driver. The version of the ToolBox driver is 3.0. I create the connection pool, use connections , everything works fine, but after a certain interval (20 minutes or so), I dont get a connection. I talked to the DBA and came to know that the UDB session lasts for about 4 hours. So it cannot be the database. I connect to Oracle using a pool too, and everything is great with it. Here is the trace I get when it fails Java.sql.SQLException: The connection does not exist. 2002-04-05 20:22:21,015 [HttpProcessor[8080][4]] ERROR com.jny.operations.mplanning.mpi.dao.LabelDetailsDao - Could not retreive Labels com.jny.operations.mplanning.mpi.common.dao.DaoException java.lang.Throwable(java.lang.String) java.lang.Exception(java.lang.String) com.jny.operations.mplanning.mpi.common.exception.BaseException(java.lang.String) com.jny.operations.mplanning.mpi.common.dao.DaoException(java.lang.String) java.util.Collection com.jny.operations.mplanning.mpi.dao.LabelDetailsDao.getLabels(java.lang.String, com.jny.operations.mplanning.mpi.common.util.Datastore) java.util.Collection com.jny.operations.mplanning.mpi.dao.LabelDetailsDao.getLdmLabels(com.jny.operations.mplanning.mpi.common.util.Datastore) java.util.Collection com.jny.operations.mplanning.mpi.service.MpiServiceBean.getLabels() java.lang.Object java.lang.reflect.Method.invoke(java.lang.Object, java.lang.Object []) java.lang.Object org.apache.struts.util.PropertyUtils.getSimpleProperty(java.lang.Object, java.lang.String) java.lang.Object org.apache.struts.util.PropertyUtils.getNestedProperty(java.lang.Object, java.lang.String) java.lang.Object org.apache.struts.util.PropertyUtils.getProperty(java.lang.Object, java.lang.String) Thank You for your time hemant
WebSphere 3.5, Struts 1.1Beta Any Issues?
Comrades, I have to deploy my webapp (powered by Struts 1.1Beta, I just love saying that) on WebSphere 3.5.x .

Now that 1.1Beta has a lot of changes, have you encountered any issues with regards to functionality such as XML parsing etc? Prerparing myself mentally, precautions/pointers are highly appreciated.

java.lang.ClassFormatError out of the Blue
I Use Tomcat 4.0.2 and Struts 1.0.2 with VA 3.5.3 Everything was perfect until, one inauspicious moment in the afternoon when I suddenly got this exception from nowhere. I have no clue as to why and how. But I do see that this is a ClassFormatException so, I moved the application related code (not struts) onto another machine where I previously deployed my app. The app was fine on this box earlier.Now, I get the same ClassFormatError there too so, It has to do with the code I moved. The Java API says that it is Thrown when the Java Virtual Machine attempts to read a class file and determines that the file is malformed or otherwise cannot be interpreted as a class file. So .class file is corrupt/malformed. But which?

Hi! There is such a feature as 'mapped properties'.
So, you can use the following constructions:
html:text property=table(name)/ // note ()
// name - name of a field of table table
html:text property=table(lastname)/
etc
in the form you only need to define:
Map table = new HashMap();
public Object getTable(String key)
{
return table.get(key);
}
public void setTable(String key, Object value)
{
table.put(key, value);
}
In brief, you don't need to define setters and getters
for every property as well as properties themselves.
Just reflect your database table to a map
(valueobject). And so on. Available as of 1.1.b1.
Good luck.
===
Iam not aware of the enhancements in Struts 1.1b
completely but would like to know if
the following
functionality exists either in Struts 1.1b or 1.0.2.
Lets say, we get a collection of ValueObjects and
populate the JSP by doing a
vo.getXXX methods.
Since Struts depends heavily on Introspection, Is it
possible that vo.setXXX is
called when someone enters a value and submits?
This would make life a lot easier.
(Pardon me if this question was already answered, I
didnt get results for my
combination of search-words )
comments please

Re: Struts 1.1Beta and Log4J, No appender Issue
Fellow Loggers,
The problem still recurs.
I tried to load my StartupManager Servlet which loads the Log4J
configuration prior to ActionServlet load but in vain.
I still get the following..
log4j: No appenders could be found for category
(org.apache.commons.digester.Digester).
log4j: Please initialize the log4j system properly
The above error seems to be simple to handle but there is an internal
mechanism that is trying to discover Log4J and is doing something with it
even before I load Log4J (via StartupManager Servlet) myself. If all I need
to do is to add an appender, which properties file is it looking for? and
where is it looking for? (/classes)??. It definitely is not looking at my
log4j.properties as I tried to add the appender there and it did not work.
Another question, slightly on a tangent though, I get a Cannot find
ActionMappings or ActionFormBeans collection while the same
struts-config.xml works fine with Struts 1.0.2
Please Advise

Thanks, Will try to make sure that Log4J initializes prior to
ActionServlet
load. Earlier, I had a Logger class which had a Category instance
initialized in a static block. Looks like my Logger was loaded prior to
ActionServlet with 1.0.2. Now, I guess I have to write a startup servlet
and
load it prior to ActionServlet as you said.

It worked with 1.0.2, but Struts did not use the commons-logging package
then, so the log messages weren't printed through Log4j, which is the
case now.
It seems that you initialize the log4j configuration after the Struts'
ActionServlet loads, so when the ActionServlet (and the Digester, and
Beanutils, etc) try to log and log4j is not yet configured, you get that
error.
I have a servlet that loads some configuration for my application. I've
set it up so that it loads before the Struts' ActionServlet, so that the
log4j system is properly initialized when called. Try do do something
similar.

I have the same setup as you seem to have (a servlet loading the Log4j

Dynamic Bean Populate on Submit.
Iam not aware of the enhancements in Struts 1.1b completely but would like to know if the following functionality exists either in Struts 1.1b or 1.0.2. Lets say, we get a collection of ValueObjects and populate the JSP by doing a vo.getXXX methods. Since Struts depends heavily on Introspection, Is it possible that vo.setXXX is called when someone enters a value and submits? This would make life a lot easier.

Fellow Strutters and Loggers, I have a webapp using Struts1.0.2 and it works fine. Iam currently using Tomcat 4.0.2 and Log4J 1.1.3.

So [EMAIL PROTECTED] Hi Ted, I just want to share this information in case someone else also goes through the same problems I did. I was able to come up with this solution after spending an entire afternoon searching through the net and archives, so if it saves people a few hours of debugging, I'll be happy. I am not sure how to categorize it or even which mailing list to send this, whether it should go to Tomcat, Struts, or Tyrex, so I decided to send it to you since you are active in Jakarta. My goal was to set up a Connection Pooled DataSource using Oracle running Struts on Tomcat. I use Tomcat 4.0.3, Struts 1.1-b1-lib, Oracle 8.1.7 classes12.zip running on Windows 98, but it should work well on Solaris/Linux. Initially, I set up the Oracle JDBC drivers under my webapp and used the datasource in struts-config.xml to access Oracle. My application consistently hung after the pool was exhausted. (For example, if I set the minCount and maxCount to 10, my webapp would hang after 10 requests) The problem of Oracle connections not being returned properly by the Struts pool was well documented in the mailing list, so I switched the datasource from struts-config.xml to tomcat's server.xml. I followed the instructions in the Tomcat jndi-resources-howto and copied the Oracle drivers to common/lib after renaming the classes12.zip to classes12.jar as suggested by the mailing list. I found my webapp wasn't running properly as the servlet would stop executing after context.lookup(). This bothered me because Tomcat was not throwing any exceptions. After some more research, I changed the debug level in server.xml from 0 to 99. This time, the log generated showed a java.lang.ClassCastException: tyrex.jdbc.xa.EnabledDataSource when the lookup() is called. A post in the tomcat-dev mailing list provided the answer: There was a conflict in the jars of tomcat and the webapp. True enough, I found a jdbc2_0-stdext.jar (83KB) that came in tomcat\common\lib, and a jdbc2_0-stdext.jar (7KB) that i had unpacked from Struts to my web-app. After deleting the 7KB jar, the lookup() executed properly. To sum up, when using a DataSource in Tomcat and Struts in the webapp, make sure to remove the extraneous jdbc2_0-stdext.jar that comes with the Struts Lib. :) Hope that helps, Walter __ Do You Yahoo!?
