struts tags in pages

[rob]

I've seen several examples of this in the mail archives but for some reason
I'm unable to make it work.

I have a base page foo.jsp


<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>







and an included page that contains a bunch of things amongst them a usage of
the struts iterator tag



">page


unfortunately it doesn't work I get complaints about an attribute having no
value.  (presumably the path
attribute)

I've also tried the <%@include .. static include without success.  I know
I'm not using the struts html:link
tag here (because I can't use mailto:[EMAIL PROTECTED]>

Hi Keith,

Yes you can use links but sometimes you need to submit the form for each
action. I'll give you an example:




Question name
Question text

Re: Multiple submit buttons solution

[Peter Severin]

Hi Oliver,

Submit input tag value is actualy the label you see in the browser. So it should be 
something like Edit,Delete etc. And don't forget i18n issues.

Peter.

Re: simper-NeXt

[Arron Bates]

Almost.
NeXt is only working off of Bean properties, and as with all beans, it 
doesn't care as to what goes on behind those method definitions. The 
constructor is one of those details it cares not about.

So as long as the simper beans have bean property conformity (eg: 
getMyProperty, setMyProperty) then the beans are ready to go with NeXt 
as they are wihout mods. I'd be very surprised if it needed mods, 
really. You can use Castor types straight up because the properties are 
valid bean properties.

A nested bean is simply one object that is returned by the method of 
another. As each property getter method has "get" on the front of it, 
we're laughin'. At the point of changing a property, you'll need that 
"set" on the front of it, naturally. For example, to get the nesting 
level deeper in my Monkey examples, I had a "fake" nested property that 
returned "this".

eg:
public MonkeyBean getOtherMonkey() { return this; }

To the internals of BeanUtils (the part of Struts that makes it all 
happen), it's treated as an entirely different object. It makes no other 
assumptions, rightly so. The system is that explicit.

Just give it a bash. Run a simper model through the NeXt tags. I lay my 
money on it working as-is.

Arron.

simper-NeXt

[John Menke]

I'm working through the Simper examples and the NeXt examples and trying to
understand how I can use both together. Here is what I have so far:


In the NeXt you associate nested beans with a parent and children
relationship by inserting a private member variable to the parent bean the
will create a new child bean:

ie.



private BunchBean bunchBean = new BunchBean();


This will give us a new instance of the BunchBean when this MonkeyBean is
created. Just what we want. Now we need to provide the getter method to the
bean under the property name "pickedBunch". This will create a getter which
will look something like this example...

Example...
public BunchBean getPickedBunch() {
  return this.bunchBean;



This enables you to make forms like this:




Monkey Name: 
Monkey Age: 


  Bunch Size: 
  Bunch Weight: 
  Bunch Price: 



Submit Form
  



In order to use the NeXt with Simper it looks like the SimperBeans will need
to include methods like those above in order to establish the relationship.

Is this correct? If so, Simper will not work with the NeXt in it's current
form.

I think if this can be coded Simper should be able to dynamically update the
contents of a database since the nested beans have their Set methods called
automatically since they are nested within the ActionForm bean?  (Aaron is
this correct?)

Inserts into the database will require creation of a new bean and can be
handled by logic in the Action that will create a SimperBean with
information obtained from the ActionForm.

It says in the Simper source code comments that deletes happen
automatically.  I'm not sure at the moment how this is going to work.  I
think you could call the Simper delete method from an Action but not sure
how the automatic part effects this.  Does the automatic feature of deletes
in Simper just mean that you don't have to call the writechanges() method in
Simper?


Any comments and additions will be appreciated.  In my opinion, the
integration of these two struts additions could be extremely useful.

Bryan, (If we have to) do you think it's worth adding some code to Simper to
integrate with the NeXt?

I use the one that is built in with Tomcat - it's called Tyrex and can be
obtained from http://tyrex.exolab.org (same folks that make Castor!) - or just
use what's already provided by tomcat.  It has worked real slick for me, and
I'd be more than happy to help anyone figure out how to use it.

Uses JNDI to do lookups and seems to work just fine.

Re: Are there any patters for pager design with EntityBeansproviding access to the database?

[Bryan Field-Elliot]

The best approach is to use a database-specific extension (since paging
is not part of SQL standard syntax).

I use PostgreSQL which has very nice and easy paging support (using
LIMIT and OFFSET keywords).

I've tried to do it once before using Oracle but had some trouble (as I
recall the "rownum" didn't work as intuitively as you would hope or
expect).

The fallback position is to load the whole resultset into memory and
store it as a session variable. This is a bad practice if the resultset
can be large (a thousand rows or more for example).

Re: Simper with MySQL

[Bryan Field-Elliot]

It's LONGVARCHAR (== java.sql.Types value of -1). Two lines of code to
be added to Simper to support this... Will be doing another checking (to
sf) in the short term.

FYI, the "null" type is 0. And just what the heck does that mean? I've
never heard of a column type of null (as opposed to a column which
allows nulls, which is totally different).

Are there any patters for pager design with EntityBeans providingaccess to the database?

[Alex Paransky]

I was wondering how people are implementing paging capability in struts.  In
other words, if the result set comes back with 2000 rows, how do you display
page 4 of 100 with 20 results per page?

Is writing custom SQL commands to depend on ROWNUM or something of that sort
always required?  Are there any easy mechanism to do paging?  Would this be
a good place to use a Statefull Session Bean and store it in to the session?

Personally, I wouldn't overreact. Poolman has always been an excellent
product, and the fact that the original maintainer isn't working on
further improvements won't change that. I'd snag the 2.0.4 release from
sourceforge and park it on a CD for safekeeping. Once it's running, it
will just keep running, and you can let it be. 

And, hey, software doesn't die, it just stops growing. And in the
forseeable future, poolman's already way big enough for me =:o)

Re: simper - versionColumn?

[Bryan Field-Elliot]

It's an unimplemented placeholder for a future version, in which I hope
to implement a basic optimistic concurrency pattern. If your tables have
an integer column dedicated to versioning, Simper will automatically
increment it on every update, after first testing to be sure that the
value hasn't changed. When I implement this, you can choose not to use
it by passing "null" as the column name for the version, which makes
your code today forward-compatible.

The use-case this all supports, is in putting a SimperBean away
somewhere (e.g. in a session variable), pulling it out later (e.g.
during some future HTTP request), and updating the row, without holding
a connection or a transaction the entire time.

RE: Poolman is gone, I hardly knew ya

Check out Torque.  It works great for me, although it may be overkill for
just a connection pool.  Doesn't the PoolMan stuff come with source?
Connection pools aren't rocket science.

According to the website:

Poolman is no more. What a bummer for me as I just learned it and
deployed it on a new project less than a week ago!

Previously, I was using the pooling mechanism built into Struts, but due
to many folks refering to it as "not industrial strength", I moved on
(to Poolman).

So what else are people using? Is there one built into Tomcat now? I
read that somewhere, I think in a mailing list message here, but I can't
seem to find any docs on it (looking at the Tomcat 4.0 docs).

Is there a mature one in the Jakarta Commons? I see a "dbcp" but I'm not
sure of it's status, if people are using it, etc.

Opinions appreciated!

Re: Poolman is gone, I hardly knew ya

[martin . cooper]

Poolman is currently still available on SourceForge:

http://sourceforge.net/projects/poolman/

I don't know what the latest status is, but I've emailed the author. I'll 
summarise to the list if I hear back.

I don't think Commons DBCP has been released yet, but Poolman's demise 
might hasten that. It's apparently based on code that came out of a 
long-running production application, so it should be in good shape.

We have a connection pooling mechanism in Expresso that one independent 
user described as "one of the best" [Don't remember his name, sorry].

It wouldn't be hard to modify it so you can get to the underlying 
dbconnection pretty easily.  [Just modify 
com.jcorporate.expresso.core.db.DBConnection to get what you need.]

Heck, it would even be a "submittable" addition since it's something that 
I've been looking to do soon.  [You could email it to me private]

Anyway, the URL is http://www.jcorporate.com/

I haven't personally been shopping around for connection pools, I just know 
it seems to work well under load.

HTH!

Re: Simper with MySQL

[Bryan Field-Elliot]

Yes,

There are two functions with Simper where we do mapping of
java.sql.Types to Java classes, and vice versa.

The error you're getting is that the functions mentioned above don't yet
understand java.sql.Type of -1. Do you know offhand what type that is?
It can be added easily to Simper, I can make the change and commit to
sourceforge CVS in a flash.

Re: how do you enable/disable a text field based on a checkbox?

[Arron Bates]

JavaScript will be your only way, working off the checkBox's onclick 
handler. You could use the onchange handler but it's implementation is a 
little fuzzy across browsers. Use onlick, get the state of the checkbox, 
and do your thing with the other field.

and formatKey

[Matt Read]

I've encountered a possible bug in the use of formatKey in . As
always it's more likely to be my error but I'd appreciate it if anyone could
have a look. I'm running the latest nightly build of struts.

Code snippets are below but to summarise, I'm using the  tag and
formatKey attribute in my JSP to refer to 3 different format keys in my
resource file. However all my values are being formatted using the
format.dollars key if the resource file entries are as below. If I remove
format.dollars then I get the strings formatted as percentages, etc. I.e.
only one format string is ever used. All my properties return datatype
"double" which I assume is something to do with the problem but I'm not sure
what. Why can't I format 4 different properties in 4 different ways using 4
different format keys?

Thanks,
Matt.

In a JSP file I have this snippet:












In my ApplicationResource.properties file I have this snippet:

format.int=0
format.dollars=$0.00
format.percentage=0.00%

The SSL extension from my JavaWorld article of Feb 15 uses the "action"

tag.  This was done to avoid the exact limitation you are finding with the

You can use a deliminated list of items, and then use the String
tokenizer to pull them out. 

StringTokenizer helperClasses =
new StringTokenizer(mapping.getParameter(),";");
int i = -1;
Object[] helpers = new Object[helperClasses.countTokens()];
while (helperClasses.hasMoreTokens()) {
String helperClass = helperClasses.nextToken().trim();
if ((helperClass==null) || (helperClass.length()==0))
continue;
// ...
}

You can also extend ActionMappings and use the digester 
feature to set your own properties. Matt Raible does this with his
workflow extension. 

http://www.livinglogic.de/Struts/

After that, you're into modifying how the ActionServlet parses the
config.

Re: Nesting Extension and persistance strategy--castor any one?

[Arron Bates]

Castor works a treat. If castor had finer grained validation mechanism, 
we could use it to validate automatically also and relieve another 
burden. I've used Castor before, but not as the model directly. But it's 
very possible. A very good system.

Castor, of course, does everything via XML Schema definition. But it's 
very complete.

Re: Pre Populating Fields - bit of a newbie question

[Jason B Menard]

Since you are just populating a field, JavaScript is an acceptable solution.
It should go without saying that you are doing server-side form validation
anyway so it shouldn't be a problem in this case.  Remember server-side
validation is a necessity.  Client-side validation (ie JavaScript) should be
thought of as a luxury for the user's convenience, but cannot be relied on
as the soul means of ensuring you are getting valid data sent to the server.

As far as pre-populating a form, in general my understanding has been that
the preferred way to do this in the Action (someone please correct me if I
am mistaken), particularly if you want to pre-populate the form with data
from your model.  But if all you are worried about is setting that date
field, JavaScript would be a cheap way to do it if it is a non-critical
issue.

[Off Topic] Setting up a Virtual Directory in Tomcat

[Matt Raible]

Does anyone know if it's possible to setup a virtual directory in Tomcat?  

I'm uploading files to a directory on my server, and (1) I want this directory
to be located where ever the user likes and (2) be able to display these files
if a user clicks on a link to them.  

Therefore, I need a virtual directory (also known as an alias in Apache) to
point to this upload directory, so users can get to the files once they've been
uploaded.  I can't use the file:// protocol, because that will make a reference
to the user's local machine.

We do NOT want to use Apache or another webserver as a front-end to Tomcat. 
One reason is because no SSL support on Windows.

Thanks,

Matt

RE: "parameter" attribute in the action-mapping... what is it?

[Bill Page]

I do what Ted does, but extend it down a level, putting a second string
tokensizer in the while loop to tokenize the following format:

key1=value1;key2=value2;key3=value3

That way they're not positional.  I also put them in map so I retrieve them
based on a key.

Re: Role-based Validation Extension Question

[Matt Raible]

Do you mean role-based actions extension?  I know that this extension allows
you to configure allowed roles to access each action.  Yes, you can do it in
your web.xml, but usually folks just protect *.do or /do/* and create an
appropriate mapping - and do all other configuring in web.xml.

RE: How to fill a String[] property-updated question.?

[Brian Richards]

The problem you're running into is that your form bean doesn't match the
Bean pattern for indexed properties.  In the populate method of the
BeanUtil class a check for IndexedPropertyDescriptor is done on the form
bean.  The javadocs for IndexedPropertyDescriptor state:

... if the argument name is "fred", it will assume that there is an
indexed reader method "getFred", a non-indexed (array) reader method
also called "getFred", an indexed writer method "setFred", and finally a
non-indexed writer method "setFred". 

So to have a "correct" Bean, you need two getters and two setters for an
indexed property.  One for the entire array and one for an individual
element of the array.  

I've always though it is a bit confusing that the tags use the
non-indexed reader while the BeanUtils use the index writer.  That's how
it will populate the page initially but not populate the bean on the
post.  

Hope this helps

Re: "parameter" attribute in the action-mapping... what is it?

[Ted Husted]

You can use a deliminated list of items, and then use the String
tokenizer to pull them out. 

StringTokenizer helperClasses =
new StringTokenizer(mapping.getParameter(),";");
int i = -1;
Object[] helpers = new Object[helperClasses.countTokens()];
while (helperClasses.hasMoreTokens()) {
String helperClass = helperClasses.nextToken().trim();
if ((helperClass==null) || (helperClass.length()==0))
continue;
// ...
}

You can also extend ActionMappings and use the digester 
feature to set your own properties. Matt Raible does this with his
workflow extension. 

http://www.livinglogic.de/Struts/

After that, you're into modifying how the ActionServlet parses the
config.

RE: Extra Path Info Problem!!! HELP!!!

[Michael Nash]

Ted:

I've been experimenting with a way of doing mappings from "normal" URL's to
Action URI's, and wonder if it's the right approach. If so, I'd be happy to
drop it in for inclusion in a release when/if appropriate, or set it up as
an optional-add on.

I took the simple approach, and added a configuration like this:



   /form/*
   /application/Something.do
   
  someParamName
  someParamValue
   
   
  1
  firstParam
   
   
  2+ 
  secondParam
   
   


Then I have a servlet called "PathHandler", which I map to "/do/*", and...

if you issue a URL like:

/application/do/form/message/here/is/a/path

it would then simply issue a forward to:

/application/Something.do?someParamName=someparamValue&firstParam=message&se
condParam=here/is/a/path

Comments on whether or not this is the right way to go much appreciated, as
I need this functionality myself soon :-)

FW: Tomcat/Struts Profiling results

[TKV Tyler VanGorder]

Hi,

For the last week and a half, a colleague and myself have been doing load/
scalability testing for our struts/jsp-based application. I would like to
share our results in the hopes that it may help someone else faced with a
similar task. We had a tough time finding real-world examples that we could
learn from. 

This is a LONG post, so I will try to summarize first:
==
Yeah..the summary is pretty long as well. 8-)

For JSP, tag-heavy applications, we found tuning parameters that may help
others get better performance out of tomcat.

We simulated a load of 50 concurrent users using automation tools that
remove any human pauses. This is roughly equivalent to 250+ concurrent,
human users. Yes...that is an estimation.

Initially, using Tomcat 4.0.1, Stuts 1.0 Final:

The IBM JDK performed MUCH MUCH better than Sun's Server Hotspot
JVM (1.3.1)

After profiling, we discovered that a significant amount of our time
was being spent in the garbage collector with the hotspot JVM. Some
of our garbage collections took a 12+ seconds! Ouch.

We attempted tweaking the various hotspot JVM parameters to see if we
could get the hotspot VM in line with IBM's performance. We did get
better results but we still had some GCs that were taking 6 seconds.

We had a large number of throw-away objects that were confusing the
garbage collector in hotspot.

We deployed the SAME EXACT application under Weblogic 6.1's servlet
engine, using the hotspot JVM, and we saw much better performance and
this was without any hotspot tuning parameters!

So we switched back to tomcat and we ran the application, using OptimizeIt
to profile the application. A majority of our time was being spent in
the constructor of BodyContentImpl because of an initial 8K char buffer
being created for EACH tag, embedded in our page. This was more pronounced
in our application because we iterated over content that had tags nested
in the iteratorthat's 8K X Number of iterations X number of nested
tags! We found that in our application most of our tags were only outputting
a few characters.

We recompiled the BodyContentImpl and changed the initial buffer size to
512 bytes. The results were dramatic and hotspot began outperforming the IBM
JDK. Keep in mind that the hotspot server VM takes a while to tune its
runtime
so was necessary to run our scalability test on the hotspot VM several
times.
I submitted an enhancement to bugzilla, its ID is 6858.

The final results were impressive!

Our application has one workflow that is VERY database intensive. It takes
a human user approximately two minutes to complete the workflow once they
are familiar with it. The transaction does 20-40 database selects with
result
sets in the range of 10-40 rows each (on average). 20+ Inserts when the
transaction is finally saved. All database activity happens in real time,
while
the user walks through our workflow.

Tomcat 4.0.1 + (our hack), using Hotspot Server JVM 1.3.1:

   Hardware: EJB server - PII 300 (-Xms64m -Xmx64m)
 Servlet/web server - PIII Dual 550 (-Xms128m -Xmx128m)
  
   Simulated 50 automated users (No human pauses) - Average transaction
speed
   21 seconds, longest time 27 seconds!
   
Of course this is our application...and each application will have its own
load characteristics, but it is a good example of struts + tomcat.

So..if our 50 automated users average 21 seconds and a human user takes
roughly 2 minutes for the same workflow then the above platform *SHOULD*
be able to support 6X the number of human users (300 users)

Thanks and I hope this information might be useful to others trying to get
a feel for how well JSP/struts will scale.

Remember, the RequestProcessor is a 1.1 thing. You'll have to be using the
nightly build for it. Of course, the beta is just around the corner. Anyway,
the Struts 1.1 DTD defines a new element called "controller". It goes under
the root element after the action-mappings. Make sure that it's in the
correct location. It should be the last element in your struts config,
unless you have plug-in's defined. Here's an example of one from my book:



Notice that many of the things that were configured in the web.xml in 1.0
are now attributes on this element. The CustomerRequestProcessor listed here
extends the Struts version and this is where I override the mehtod.

You don't have to do anything with the ActionServlet. In fact, since the
RequestProcessor is where all of the meat is now, you can just use the
Struts ActionServlet as is and there's usually no need to subclass it.

You could always extend ActionMapping (or ActionConfig for 1.1) to accept
more parameter type attributes.  Of course at that point, you're extending
the framework but's that neccessarily a bad thing.

Matt,

   I had one other idea that I wanted to share with you. It came to be as I
was just starting to work on the security chapter for the Struts book. This
is for the case where you have a small number of actions that the user
needs to be logged in for, rather than all of them.

What if you added a value like "checkSession" using the parameter attribute
in the action mappings that required the user to be logged in. In the
"processPreprocess" method, you can look up the mapping for the action that
has been requested using

ActionMapping mapping = findMapping(path);

which is available in the ActionServlet class as well.

Once you have the mapping, yoy can call "getParameter", which will return a
String for the parameter in the ActionMapping. If no value is specified, a
null is returned. If "checkSession" of some other value is present, then
you know to check to see if the session is present and valid. If so, return
true, which allows the ActionServlet to continue on. Otherwise, you can use
the ActionMapping that you already found for the action and return to the
login page. You are probably better off declaring a global forward and
using the findForward(String name)  method in the ActionServlet to locate
the global login forward and forward to this.

By doing it like this, you make the whole thing very generic and
declarative. You are free to change which actions need to have the user
logged in without modifying any source code. The "processPreprocess" method
stays completly generic.

What does everything about this approach? I think I'll mention this in the
security chapter of the book.

RE: Pre Populating Fields - bit of a newbie question

This is an old, outdated argument; 99.99 percent of the web uses JavaScript.
Instantiating an object is very expensive, relatively speaking.  But it's
your app; do what you want.

You can use JavaScript only if you guarantee that every user of your 
application has a browser that supports JavaScript and it is enabled.  
You're probably OK if you are intranet, but with internet applications, 
you never know if someone is running WebTV or something like that.

In my mind, the point of creating an object for this is to make sure I get
a date even if JavaScript isn't enabled in the user's browser.  The time
to get a date is in milliseconds I would bet.  It's not much overhead at
all.

 Hi Craig. Since, AFAIK, the digester blindly instantiates all of the
implied objects in your database file, I think that you'll need to parse the
database file independently. You might try parsing the database file
using JDOM, extracting the elements that you want and passing that
snippet to the digester. I think that utilizing JDOM, you'll get working
code much faster than you would with raw SAX parsing. I have used
JDOM but I haven't tried utilizing it with the digester - just an idea.

Hi All,

Has any one tried to use struts with castor XML frame work for persistence
if so could you please share your experiences and throw soem guidance.

1-As a starting point i have tried to generate java classes from a schema
using source generator of castor.

2-I have made ActionForm as my super class to the generated classes.

3-Unfortunately if i want to use the marshalling and un marshalling power of
castor i have to generate marshall/unmarshall/valiate methods, this is where
i run into problems as the validate method of ActionForm clashes with them.

4- To over come this i may have to generate two sets of beans with the
source generator one as FormBeans and one with marshall/unmarshall capacity

5 Then i  can use some commons utilities to transfer data from form beans to
data beans and persist them

6 I feel this will be a nice way of xml round tripping, even though i am
aware of similar solutions using digester and other utils.

Please let me know if  this process can be refined if any one has similar
experience

RE: Pre Populating Fields - bit of a newbie question

[Jay sissom]

You can use JavaScript only if you guarantee that every user of your 
application has a browser that supports JavaScript and it is enabled.  
You're probably OK if you are intranet, but with internet applications, 
you never know if someone is running WebTV or something like that.

In my mind, the point of creating an object for this is to make sure I get
a date even if JavaScript isn't enabled in the user's browser.  The time
to get a date is in milliseconds I would bet.  It's not much overhead at
all.

RE: Pre Populating Fields - bit of a newbie question

[Maturo, Larry]

Hi,

The first statement was:
I need to have a startDate and endDate field in my form, and I'd like to
prepopulate the endDate field with today's date.

Easy to understand.
 
The second statement was:
There's a bean that has set/getEndDate() methods, and I get to the form 
from an Action.perform() call

This is ambiguous.  Is the bean that has set/getEndDate methods the form
bean?  If so, you just need to instantiate a copy of your form bean within
your action, convert today's date to a string, store it in the form
bean using setEndDate, and store the form bean in the request or session,
depending on how you set up your mapping in struts-config.xml.  Note that
the name you need to store the form bean under is the name you used when
setting it up in struts-config.xml.

I hope this helps, if not please repost with more details.

A third option people have mentioned is to serialize the form-bean as a
single hidden field. As part of validate, you can repopulate any null
fields. 

Never actually tried this one myself, but it seems clever.

Has any one used struts with castor as a persistence mechanism....

[rajesh kalluri]

Hi All,

Has any one tried to use struts with castor XML frame work for persistence
if so could you please share your experiences and throw soem guidance.

1-As a starting point i have tried to generate java classes from a schema
using source generator of castor.

2-I have made ActionForm as my super class to the generated classes.

3-Unfortunately if i want to use the marshalling and un marshalling power of
castor i have to generate marshall/unmarshall/valiate methods, this is where
i run into problems as the validate method of ActionForm clashes with them.

4- To over come this i may have to generate two sets of beans with the
source generator one as FormBeans and one with marshall/unmarshall capacity

5 Then i  can use some commons utilities to transfer data from form beans to
data beans and persist them

6 I feel this will be a nice way of xml round tripping, even though i am
aware of similar solutions using digester and other utils.

Please let me know if  this process can be refined if any one has similar
experience

Regards
Rajesh

Re: Poolman Setup with Struts under tomcat 3.3

[Jin Bal]

You're probably already doing but  just in case:

when you get your datasource use the static method in the PoolMan class
(PoolMan.findDataSource)
This will return you a datasource from poolman.
The fact that it works when you put the datasource tag back in the struts
config xml suggests that it is still trying to us the struts datasource
object (actionservlet.findDataSource i think).

RE: Handling exceptions

[Hani Hamandi]

Hmm, well, I think you should care about that.
If a JVM exception happens, there is most probably something wrong going on.
If you don't catch the exception/error, your user will get an ugly 505
server error or something like that. Your decision will depend on whether
this is okay in your application or not (from a product management point of
view). In our case, it was not. We prepared a nicely formatted Error page
with phone numbers and contact information apologizing for the inconvenience
... etc. We forward to this Error page is served whenever an "abnormal"
exception takes place, i.e., when we end up in the "catch Throwable" block
in validate() or in perform().

RE: "parameter" attribute in the action-mapping... what is it?

[Steve Earl]

Does anyone know if you can specify more than a single parameter on the
actionMapping definition within the struts-config.xml file?

The reason for the question is that I'd like to do something similar to
what's specified below - have an action which processes several related
tasks using a parameter to distinguish them. However, I'm also using Steve
Ditlinger's ssl tag extension and that requires a parameter on the
actionMapping of "secure".

All advice appreciated.

It's a general purpose attribute you can use to pass any desired
information into the action from the struts-config.xml file.  You can
access the parameter's value within the action class via the
mapping.getParameter() method.  For actions requiring multiple steps, the
parameter is often used to indicate which step the mapping is associated
with.  For example:

...

Hi All,

I am not the expert in the field of designing OO persistence mechanisms.

I am a fan of nested beans and also i have been playing with castor lately.

So am thinking if we can map our monkey object schema to a db schema (I can
hear a lot of thats easy). Then it should be a snap to marshall/unmarshall
monkey beans  (nested in general) into XML files/ data base tables.

I would start playing with it as soon as i have time.

Re: Nesting Extension and persistance strategy--castor any one?

[rajesh kalluri]

Hi All,

I am not the expert in the field of designing OO persistence mechanisms.

I am a fan of nested beans and also i have been playing with castor lately.

So am thinking if we can map our monkey object schema to a db schema (I can
hear a lot of thats easy). Then it should be a snap to marshall/unmarshall
monkey beans  (nested in general) into XML files/ data base tables.

I would start playing with it as soon as i have time.

Poolman Setup with Struts under tomcat 3.3

[Satish Jeejula]

Hello All,

I am try to use poolman with struts under tomcat 3.3. I placed poolman.xml
in the web-inf\classes directory and removed the datasource tag from
struts-config.xml.

But it is throwing following error... 

java.sql.SQLException: SQLException occurred in JDBCPool:
java.sql.SQLException:
 Io exception: The Network Adapter could not establish the connection
params: oracle.jdbc.driver.OracleDriver,
jdbc:oracle:thin:@216.136.75.139:1521:proddb.

But if I put the datasource tag back in struts-config.xml .. it works fine.
But I am not sure which connection pooling (Poolman or Struts) it is using
when I say getConnection() in my code. 


Do I have to place the datasource tag also along with poolman.xml???

It is very urgent for me to solve this problem.

Any help is appreciated ... thanks

Satish

that looks it is the output from the toString method of an array or collection

Re: design question

[Ted Husted]

At this point, I rarely write custom Actions any more. Now I try to use
a framework action to handle all the usual action-stuff, and pass it the
name of a business bean to invoke as part of the ActionMapping. At this
point, I'm creating moderately complex application using only the stock
actions in the scaffold package. Lots and lots of business beans, but
very action classes. 

http://cvs.apache.org/viewcvs/jakarta-struts/contrib/scaffold/src/framework/main/org/apache/scaffold/http/

What I'm thinking about now is extending ActionMapping so that it has
the same type of functionality embedded in the DispatchAction. To wit,
let you specify an object to instantiate and a method to call from the
ActionMapping. There could actually be a couple of different method
signatures to call, maybe a perform, an execute, and then an invoke that
just took a single object (the ActionForm), but have them each return a
collection. There could also be an attribute to give whatever they
return a name, and pop it into a context. 

I think we can really dispense with most actions almost completely, and
configure most everything from the Struts config, as Craig envisioned in
his workflow proposal. Most of what the Actions do is very predictible,
it's just the wee-bit of business logic in the middle that makes one
different from the other.

Pre Populating Fields - bit of a newbie question

[Mattos, John]

Hi

I need to have a startDate and endDate field in my form, and I'd like to
prepopulate the endDate field with today's date. There's a bean that has
set/getEndDate() methods, and I get to the form from an Action.perform()
call

What's the best way to prepopulate that field?

RE: validate() and session expiry

[Chuck Cavaness]

You could always extend ActionMapping (or ActionConfig for 1.1) to accept
more parameter type attributes.  Of course at that point, you're extending
the framework but's that neccessarily a bad thing.

That looks good too but given that you're only allowed to have one
 per action mapping it would preclude the use of parameter for
anything else. It would definitely make DispatchAction difficult to use. I
do like the idea of being able to configure this in struts-config.xml
though. Maybe it could be implemented as requiresSession="true"?

Subject: RE: validate() and session expiry


Matt,

   I had one other idea that I wanted to share with you. It came to be as I
was just starting to work on the security chapter for the Struts book. This
is for the case where you have a small number of actions that the user
needs to be logged in for, rather than all of them.

What if you added a value like "checkSession" using the parameter attribute
in the action mappings that required the user to be logged in. In the
"processPreprocess" method, you can look up the mapping for the action that
has been requested using

ActionMapping mapping = findMapping(path);

which is available in the ActionServlet class as well.

Once you have the mapping, yoy can call "getParameter", which will return a
String for the parameter in the ActionMapping. If no value is specified, a
null is returned. If "checkSession" of some other value is present, then
you know to check to see if the session is present and valid. If so, return
true, which allows the ActionServlet to continue on. Otherwise, you can use
the ActionMapping that you already found for the action and return to the
login page. You are probably better off declaring a global forward and
using the findForward(String name)  method in the ActionServlet to locate
the global login forward and forward to this.

By doing it like this, you make the whole thing very generic and
declarative. You are free to change which actions need to have the user
logged in without modifying any source code. The "processPreprocess" method
stays completly generic.

What does everything about this approach? I think I'll mention this in the
security chapter of the book.

Chuck

Re: Multiple submit buttons solution

Hi Peter,
I just use links to do this. (I think you can use an Image as well).
Buttons are a bit ugly so I don't need this functionality.
There's lots in struts so I don't favor adding more.

Role-based Validation Extension Question

[Emaho, Ghoot]

Hi,
 
I think I might be missing something here. Can someone tell me what the Role-based 
Validation extension gives you over, say, setting security restraints in the web.xml ?
 
I can set constraints on individual actions by mapping them in the web.xml. So what 
else does the extension give the developer ? 
 
This isnt a criticism, i just need someone to point it out to me. For the life of me I 
cant figure out what else you get, and i ant see any reason to use it at the moment.
 
Anyone who can point out the wood amongst the trees will be thanked kindly !

Re: design question

[Ted Husted]

A third option people have mentioned is to serialize the form-bean as a
single hidden field. As part of validate, you can repopulate any null
fields. 

Never actually tried this one myself, but it seems clever.

Re: How to use the html:text tag properly.

[keithBacon]

I'm pretty sure if you use get/set in your form bean you should not use value.
It specifies the literal value to display in the field (I think? - as I never
use it).

RE: validate() and session expiry

[Matt Read]

That looks good too but given that you're only allowed to have one
 per action mapping it would preclude the use of parameter for
anything else. It would definitely make DispatchAction difficult to use. I
do like the idea of being able to configure this in struts-config.xml
though. Maybe it could be implemented as requiresSession="true"?

Matt.

Subject: RE: validate() and session expiry


Matt,

   I had one other idea that I wanted to share with you. It came to be as I
was just starting to work on the security chapter for the Struts book. This
is for the case where you have a small number of actions that the user
needs to be logged in for, rather than all of them.

What if you added a value like "checkSession" using the parameter attribute
in the action mappings that required the user to be logged in. In the
"processPreprocess" method, you can look up the mapping for the action that
has been requested using

ActionMapping mapping = findMapping(path);

which is available in the ActionServlet class as well.

Once you have the mapping, yoy can call "getParameter", which will return a
String for the parameter in the ActionMapping. If no value is specified, a
null is returned. If "checkSession" of some other value is present, then
you know to check to see if the session is present and valid. If so, return
true, which allows the ActionServlet to continue on. Otherwise, you can use
the ActionMapping that you already found for the action and return to the
login page. You are probably better off declaring a global forward and
using the findForward(String name)  method in the ActionServlet to locate
the global login forward and forward to this.

By doing it like this, you make the whole thing very generic and
declarative. You are free to change which actions need to have the user
logged in without modifying any source code. The "processPreprocess" method
stays completly generic.

What does everything about this approach? I think I'll mention this in the
security chapter of the book.

that is true for data entry screens. Not for various display screens where
you only need an identifier to retrieve your information from a database.

For data entry screens I think I will have to rely on sessions, since I like
my data in the database to be complete otherwise you should have a worker
thread to check your database for incomplete fields and destroy these
incomplete records after a number of time/days/weeks.

RE: default key?

[Hani Hamandi]

Actually, I think I was misunderstood.
I don't want it to print anything for the user. What I was thinking of is
something like this:



What this means is "if you don't find "someKey" then don't throw an
exception, but rather try the default key "someOtherKey", and if *that*
doesn't work, then throw an exception.

Even better:



I would make both defaultKey and defaultValue *optional*. If defaultValue is
specified, and if none of the keys is found, then simply the default value
is displayed.

What do you guys think?

Re: "parameter" attribute in the action-mapping... what is it?

[Donald Miller]

It's a general purpose attribute you can use to pass any desired
information into the action from the struts-config.xml file.  You can
access the parameter's value within the action class via the
mapping.getParameter() method.  For actions requiring multiple steps, the
parameter is often used to indicate which step the mapping is associated
with.  For example:

...

I hope this helps.  Take care.

RE: design question

[Ronald Haring]

I have one big problem and one minor problem with keeping information in
sessions
- it takes memory, and you have no way of telling when this will released
(sure if session timeouts, then you might suspect that it will be cleaned
any time soon, but its always up to the gc to do that, so never sure)
- when using load balancing you have to use sticky redirection to the server
maintaining the session object for this user (but this is not very important
yet and I know you will have to do that with only a sessionid key in the
client object as well)

How to use the html:text tag properly.

[Alex Colic]

Hi,

I am trying to get the value attribute to work in the text tag. I have an
'ITEM' bean with two properties. One is set up when the user selects an
item. When they go to a page I want the page to display the existing value
in 'item.primeLocation' and I want the text box to be prefilled with the
value from 'item.primeLocation' but have the text user input go into
'newPrimeLocation. Both parameters are within the ITEM bean.

I think the value attribute is supposed to get the from the 'primeLocation'
but I actually get "primeLocation" passed into the text box. I must be doing
something wrong.

Thanks for any help.

Multiple submit buttons solution

[Peter Severin]

Hi folks,

I've been searching for a solution for multple submit buttons in the
same form
and how it can be achieved without using javascript. Summing up
different suggesstions
I came with the following solution. We can encode additional parameter
values into the submit button name and make struts handle this
parameters transparently for us.
For example we could have the following html code:


ActionServlet would detect this parameter and auto populate the form
with parameter 'deleteItemId' and value '10'.
To extend this idea further we could have the following code:




In the action we could test form.getAction() parameter value and to
dispatch to the coresponding delete/edit method inside which we coule
use form.getItemId() to execute the operation.
You've got the point.
I would like to hear comments and suggestions on this. I am willing to
post the actual code in the future if the idea proves itself valuable.

Regards,
Peter.

If you use relative links in your page, you should place the 
tag inside the  element of your page.  It will render a base tag so
that relative links will not appear to be broken.

There's really no reason not to keep the data in the session.  The session
is server-side and is not transmitted to the client, so it's secure.  I
can't think of any other reason you would be uncomfortable with using the
session, but if you have a different concern please feel free to voice it.

[Eddie Bush]

D'oh!  I actually wanted it in a TAG but that will work fine.  I had
forgotten about that method of obtaining it.

Thanks so much for your patience!

RE: design question

[keithBacon]

You have to keep the data in the session or write it to the database. (Storing
it on each form as hidden fields seems too fiddly to me).
Unless you have huge volumes I actually prefer to save it on the database &
have a status field that indicates the data is incomplete.
