RE: Struts Productivity Survey

[Manomohan K Kalathil]

Greg, 
Agree completely with what Jaaron has to say. Your best bet is to divide up
the work. There could be people who are good at JSPs, taglibraries, HTML. Few
others who have exposure to web development using servlets etc should be
trained indepth on struts and be asked to develop all actions and associated
artefacts. Note however that this approach requires that the lead of the team
should have his/her fingers into all pieces of the pie. In your case you will
need more than one lead and the leads should know and enforce the interfaces
between the web team and the struts team and the business layer folks. I have
been on one such role and believe me it is quite nightmarish for the first
few weeks. But once everyone gets a hang after the first integration. 
Regards
Mano

Greg,

I had a similar situation recently, although not nearly at the scope you're
currently facing.  I'm not sure if it was an advantage, but I had a handful
of
developers who were completely new to java, object-oriented programming,
everything.  One had some COBOL experience, the rest were database people
(Oracle P/SQL programmers).  Luckily I had the other project leader on my
side
and he agreed Struts was the way to go.

Personally I think Struts is easy to grasp IF you break it down.  My plan was
something like this:

1. Get everyone up to speed on the general idea of MVC and Struts.  Basic
definitions.  Perhaps show an extremely trivial example.

2. Divide up the work.  View people don't need to understand how Actions work
completely.  Likewise Action and Model people don't need to understand Views
or
Taglibs.  As long as you have well defined interfaces and know what needs
passed to what, you can teach people on a need-to-know basis.  For many
developers I think this is easier.  It gives them something to work on.  The
ambitious ones will do their own homework.

3. Develop one part of the application completely to be used as a reference. 
In my case, the application had three main parts to it.  I wrote almost all
of
part one, and then turned it over to the team for parts two and three.  I did
a
complete walk through with them and then after that I was just on support.

We had the whole process moving within a week.  It was a hectic week mind

Good Luck!

You can also use hidden fields (basically client-side state management), 
or application-managed durable storage (e.g RDBMS).


You have to take the decision based on your application's performance
expectations.

The cleaner approach is to define the scope of form as "session" and storing
everything in formbeans, nowhere else.
some readonly information can be stored in application context also.

Well you may choose to store some information in stateful session beans and
some in formbeans (HTTP session) but I would not suggest to keep the scope
of formbeans as "request" unless the screen is totally stateless.


Or unless the application has to scale to very large volumes, in which 
case you want to be very careful about creating too many session-scoped 
objects.

Hi everyone,

I'm wondering about the ways of managing sessions in Struts and wanted
to know out of these two ways which was the better way of doing things:

1. Storing things within the standard servlet session

2. Using a UserWrapper object and storing that within the session.

Is the second way more preformance intensive or not and which is best
practice?

Many thanks,
Jon Holloway.

Re: Security Filter and ActionForm

[Max Cooper]

You might not want to tell users what was wrong for security reasons. If
they type a username/password and can get a "username invalid" or "password
invalid" error, they will know when they have guessed a good username.
"passwords can only contain letters and digits", etc. also give away
information that you may want to protect. This may not be a major concern,
but it is good to be aware of such issues.

Assuming the info give-away from the specialized error messages is not a
significant concern, you could have a Struts Action as the error page. It
will populate an ActionForm, do validation, etc. It would be a second check
(inefficient) but you wouldn't have to modify (and maintain your
modification to) SecurityFilter to do it.

Perhaps some sort of error type system could be setup in SecurityFilter. It
would require changes/additions to the realm interface, but perhaps it is
worth it for this added functionality. It might be nice to incorporate
support for rules like "you have to change your password every X days", etc.
as well.

You'll have to use expression scriptlets for the attribute value.  In those
expressions, you can produce any Java expression you want.

If you want/need to avoid scriptlets, then you'd have to use a more involved
process, using Struts-EL, along with a class that uses reflection to load
"static final" constants into a HashMap which can be referenced through the EL.

That would be your cause.  You certainly want to set a higher level than

I haven't work on larger projects, but here is my take: As another
poster mentioned, 50 people are too much just for the Web stuff on one
project IMHO. Second I would never let people get on such a big project
with no experience with the used framework.

My experiences:
I'm currently trying to get somebody who did nothing but PHP to Java and
Struts. He found a tutorial, I gave him also Ted's book,
showed a bit the struts-examples. I also told him to look at our
current smaller (30k loc) project and change some appearance stuff
first, then some small functionality and then go into business layer
things, i.e. database etc. It's going slow. I'm being asked "Why is it
so complicated? Why do I need these 100 files for doing just one
thing??"

Last summer I booted somebody with no programming experience on Java
and Struts, doing it like this: First, get Java in, using the tutorial
on the sun site (not of interest to you). Then the Tomcat examples, Java
beans, HTTP parameters. Then I let him write a small class with a
specific problem (not so easy paging algorithm). Then apply it to
Tomcat/Struts. He learned most stuff from looking at the application
on the go.

I think important though to have a build environment ready (ant, deploy
to tomcat, etc.) so they can try their stuff out quickly. Remember
Struts is a framework, every project has its own way / pattern to
use it. New people can pick this style up and learn much faster.

It depends so much on the people. Some learn so quickly I just tell them
"Take a look at this or that." And they come back ready to use it and/or
apply it. Others I have to explain and they just "don't get it."

Security Filter and ActionForm

[Curtney Jacobs]

Greetings!!

I have a login ActionForm (LogInForm) and a associated login Action class 
(LogInAction). When the form is submitted, the request is intercepted by a 
Security Filter. The Security filter authenticates and perform necessary 
authorization checks on the user via a ldap server.

If the user authentication fails, let say because of an invalid password, how 
can I use my ActionForm (LogInForm) to indicate this error to the user?

I am aware that the Struts ActionForm and Action  have not even been 
instantiated/intitialize, since the security filter intercepted the request.

I have thought of setting an attribute in the request scope, for example, an 
"invalid flag" that the ActionForm validate method can check for. This will 
then trigger the display of the login form and asociated error message to the 
user.

I am not sure if the above is good practice :(

Any suggestions or comments will be much appreciated.

Re: Struts Productivity Survey

[Johan]

Greg,
You have a big problem. The hardest thing is not learning new stuff but 
estimating the learning curve for others. Personally it took me about 2 
weeks to grasp the concepts and getting up to speed. Why two weeks, 
because people are banging on my door waiting for me when I have 
finished the product. So I have to. When I try to learn something just 
to learn something it takes months.

What you can do is take a few ( max 4 ) people and ask them to build a 
struts application within 4 weeks max. Changing you should do in small 
steps. And watch their progress. Next you can add another 4 to that 
small team and let them start building the first part. See how it's 
going and you can make a more relaible estimate. Tell your boss that you 
can only estimate by trying in small. If he agree at this point you have 
already 8 people who have used the framework. And since your program 
isn't only about struts, but also on java and more start with those who 
know java. Then those who know C++.

And those who only know VB there is some bad news. For me it took about 
two years of studing the java architecture and language before I was 
comfortable in programming java. And I had only MS Access and some VB 
experience

Hope it's helpfull

One of my tasks is to quantify how long it will take developers to get up to speed on Struts to estimate the cost of moving over.

I learned Java, JSP/Servlets, and Struts pretty much all at the same time, and it clicked easily for me.  But I learn new things easily and am not intimidated by new things.  Others seem to have had varying levels of difficulty picking it up.  The team that I worked on back then had little trouble with it.

Greg, 

Wow, I don't envy your assignment.  There is one thing that I 
have learned
over the years as both a developer and project manager, 
people learn at
different rates, and pick up new skills very differently.

In the case of the people who only know C++, the transition 
to Java will not
be difficult.  If they have had no exposure to HTML and web 
development,
then the transition to JSP's will take them a little longer.  
I've know some
really good low level C++ programmers who just cannot get the 
hang of HTML,
much less the tag library underlying struts.  These guys are 
better suited
for the server side and EJB side of development.

As for the VB programmer, your job is going to much more 
difficult.  Many of
the VB programmers I have meet over the past 2 years have had 
no exposure or
training in Object Oriented Programming (OO).  Many have 
moved to VB from
mainframe jobs that they started back in the 70's and 80's.  
For those on
your staff who have had exposure to C++ in college, the move 
to Java will
probably be easier than for those on your staff you have come from a
mainframe background.

As to Struts, JSP's and the tag libraries.  You are looking 
at training
these people in ALL three of these concepts/technology.  I 
would strongly
suggest that you start out your training class in JSP's using 
the Model 1
concept the first few days, and then introduce Struts and the JSP tag
libraries for the duration of the training course.

In all, my experience in training people in a combination of 
on the job and
classes has been as follows:

For those with heavy C++ experience, moving to 
Java/JSP/Servlets/HMTL took
about month before these people were productive.

For those with some exposure to C++ and OO, but no work 
experience, it took
about 2 months for these people to be productive.

For those with no exposure to C++ and OO (mainframe 
background), it took
anywhere from 4 months to 9 months before these people were 
really useful
and productive in the work environment.  A lot depended on 
the attitude of
the person, and their willingness to learn new programming 
skills AND new
programming/software concepts, particularly OO.  If you can 
get over the
hurdle of the OO concepts, then you are 2/3 of the way there.

If you add struts and HTML to the equation, I would add an 
extra 2 to 4
weeks, before the staff is really productive and useful in the work
environment.  

Keep in mind again that people learn at different rates, and 
that they learn
in different ways.  The approach you take to exposing and 
training these
people may not work for the entire group, and you may need to 
take extra
time and try different approaches with some in the group.

Good luck, this is one assignment that I don't envy you on.

RE: ActionErrors question

I am not aware of any way to do what you propose.  As far as I know all an
ActionError object does is hold the key you want to use. If bundle is not
specified in your JSP, then it defaults to the default resource bundle. In
this case that key has to exist in that bundle. Otherwise you have to
specify in mailto:[EMAIL PROTECTED]]

RE: context relative image reference in a CSS file

[Dan Payne]

Duh. I forget what it's called when you develop an overly complex solution
to a *very* simple problem but that's exactly what I was doing. Thanks Joe
and Craig and all others who replied. I was thinking the path would be
resolved from the file that contained the stylsheet link, not from the
stylesheet file itself. I threw in the relative reference and it's working
like a charm.

Thanks again!

Okay, well I couldn't swear that "list-style-image:" works like
"background:" in CSS sheets ('cause I haven't used it), but I would assume
that it does.  We use something like this all over our CSS:

background: url(../images/icon_confirm.gif);

The url reference above is intepreted by the *browser* relative to the
location of the CSS file itself.  What file(s) the link to your CSS file is
found in is irrelevant for this interpretation, only the location of the CSS
file matters.

Re: Session Management

[Puneet Agarwal]

Session Management is required to achieve persistence. there are two manner
in which persistence can be achieved.

1. storing the information in HTTP session (possibly in session scope)
2. Storing the information using stateful session beans.

You have to take the decision based on your application's performance
expectations.

The cleaner approach is to define the scope of form as "session" and storing
everything in formbeans, nowhere else.
some readonly information can be stored in application context also.

Well you may choose to store some information in stateful session beans and
some in formbeans (HTTP session) but I would not suggest to keep the scope
of formbeans as "request" unless the screen is totally stateless.

Hi everyone,

I'm wondering about the ways of managing sessions in Struts and wanted
to know out of these two ways which was the better way of doing things:

1. Storing things within the standard servlet session

2. Using a UserWrapper object and storing that within the session.

Is the second way more preformance intensive or not and which is best
practice?

Many thanks,
Jon Holloway.

how do i validate number of check box selected by user in DynaValidatorForm

[Ashish Kulkarni]

Hi,

I am using DynaValidatorForm, and i want to validate
number of check boxes selected by the user, 
for example to display details, user must select
atleast one checkbox on the the main page before
clicking display details button,
or user must select only one check box for specific
operation..
How do i define this condition in validation.xml??

RE: turning form parameters into queries

[keithBacon]

Below is a class of mine that is a bit primitive but does the job. There's
probably plenty wrong (like using integer constants instead of type safe enum) 
with it as I'm a bit of an amateur. With queries I reckon the usual rules of
MVC go out the window & you design for
1 - performance
2 - minimum lines of code.
3 - simpicity - You can put junior programmers to work on this sort of code.

 ..DL = Data List object. It has no GUI code but needs a method for each
combination of parameters. It has no SQL but uses the data objects created by
classes that have the SQL.

=
I think that once a system has many queries the database design must be stable
so it's not so bad if the GUI is bound to the DB design.  (OO heresy!)

If u have a web only interface an alternative is to build the SQL in your
ActionForm & have a generalised system that runs the SQL & returns a
List/Collection of type you specify. Some such thing must exist. You just put
the collection in the request for the JSP to display.
thanks,
Keith.

RE: Struts Productivity Survey

[Greg.Reddin]

Well, the question was somewhat, but not entirely hypothetical.  The 50 is probably 
more like 30.  The problem is really another "my framework is better than yours" 
debate and we're pushing to use a Struts-based framework going forward instead of a 
home-grown.  One of my tasks is to quantify how long it will take developers to get up 
to speed on Struts to estimate the cost of moving over.

I learned Java, JSP/Servlets, and Struts pretty much all at the same time, and it 
clicked easily for me.  But I learn new things easily and am not intimidated by new 
things.  Others seem to have had varying levels of difficulty picking it up.  The team 
that I worked on back then had little trouble with it.

Re: Error in testing a Custom Tag

[CFineman]

Hi Elma,

You probably need to give folks more background then this (e.g. we are
running under weblogic). From what I can tell it looks like your
application is not properly deployed. If you are still having problems,
stop by and we can chat about it.

I'm not sure if this is related to custom tags, but when I created a TLD
file and it's associated objects(class,jsp and updated web.xml), I get the
following error:

   

It doesn't seem to be related to the xxx.jsp file.

Can someone help with this???

Upload problem: Stream ended unexpectedly

[Peter Severin]

Hi,

One of our customers has a problem when trying
to upload a large file. We are using struts1.1-b2 with "Apache 
Tomcat/4.1.12-LE-jdk14" with IIS in front of it. We use 
CommonsMultipartRequestHandler class. The upload works as expected for 
others. Have anyone experienced something like that ?

Stacktrace is below.

Re: Struts Productivity Survey

[V. Cekvenich]

In this case, does the consultant/architect:
a. have previous deployed Struts applications,
b. or does the consultant "know of" Struts?

In case a. one should have an idea of how long it takes to train and 
develop. One opinion for time frame range is newbie developers take 
about a few days per MVC, and experienced programers do a few MVCs per 
day (of an average complexity MVC - bean, dao, view, action. 
JasperReports take about the same. Assuming you have decent 
requirements, use an iterative process and have a good DBA). Also, 50 
developers for 100 screens?

In case of choice b. ... lets see nothing comes to mind.

You're a consultant or an architect who has been tasked with building a Struts application with 100 screens.  You're actually migrating an application which was originally written as a fat client app in VB and the server was written in C++.

You have about 50 developers who know VB and C++ pretty well.  Some of them know Java/JSP/Servlets very well.  Some of them know it very little.  None of them know Struts.

Your job is to estimate the cost of getting these folks up to speed on Struts.  You already have the application design.  THere's going to be a thin business layer called by the Action classes that will use EJB session beans to provide application functionality.  Fairly simple.  You have to train these people to use Struts, create actions and pages, and write the web-tier business layer.  Somebody else is doing the EJB stuff.

How do you estimate that cost?
How long do you think it will take for these various developers to write their first business function?
How long to do the next one, etc?

I agree 100%. I looked at Struts for the first time in April 
2001 mainly
for the forms stuff, really wanting to use it. I've read the UserGuide
and said "What is he talking about!?" Half a year later, with a real
project at hand it went much faster, using the /example stuff. Back
then there were no DynaForms, no Tiles, no Nested, all the stuff that
makes things much easier now. The pages that are now the Taglib API
Reference were the best resources back then.

Greets,
Andreas.

repost about problem with Declarative Exception in DispatchAction

[Rick Reumann]

Sorry for this repost, but I'm still pretty stuck.
Hope someone could help with this..

If I use a normal Action and declare an exception in the action
configuration in the config file, everything works perfectly if that
Exception is thrown.

However, when normally I like to use DispatchAction and I'm having
trouble getting the declarative Exception handling to work in
DispatchAction methods. Apparently just adding the appropriate throws
clause to the DispatchAction method doesn't work. The log will show
that the exception was thrown but the DispatchAction didn't handle it.

Is there something I need to do differently to configure
DispatchAction methods to handle declaritive exceptions?

Thanks for the help?

Taglib with Dynaforms

[LT Yield]

Hello all,

I just started using DynaValidatorForms for my form
beans instead of the traditional way.  But I am having
problems retrieving the bean elements in
html/bean/logic tags.  Do these tags support the
Dynaforms or do I need to alter the tags on my own to
do the appropriate getters and setters for dynaforms?

Any assistance would be greatly appreciated,
Lionel

I agree, the Map method isn't very straight forward for simply adding
2-3 params to the link.  The only thing to remember with the traditional
method is to encode the parameters.

Easiest way to pass multiple parameters on a html link.


Use the standard anchor tag.


eg:

"/>&salary
nce="/>">

Here the myForm should have indexed getters for empBean

Clas MyForm(){
List empList = new ArrayList();
getEmp(int index){
while(empList.size< index){
empList.add(new EmpBean());
}
return (EmpBean)empList.get(index);
}
}




Very, very ugly but works just fine!

I think the struts way(using map)is not very easy alwqys...

Re: Session Management

[Puneet Agarwal]

Session Management is required to achieve persistence. there are two manner
in which persistence can be achieved.

1. storing the information in HTTP session (possibly in session scope)
2. Storing the information using stateful session beans.

You have to take the decision based on your application's performance
expectations.

The cleaner approach is to define the scope of form as "session" and storing
everything in formbeans, nowhere else.
some readonly information can be stored in application context also.

Well you may choose to store some information in stateful session beans and
some in formbeans (HTTP session) but I would not suggest to keep the scope
of formbeans as "request" unless the screen is totally stateless.

Puneet

Hi everyone,

I'm wondering about the ways of managing sessions in Struts and wanted
to know out of these two ways which was the better way of doing things:

1. Storing things within the standard servlet session

2. Using a UserWrapper object and storing that within the session.

Is the second way more preformance intensive or not and which is best
practice?

Many thanks,
Jon Holloway.

Either way is fine.  It's highly unlikely that choice 2 would have any 
noticable performance problems.

I'd bet you forgot to add the <%@ taglib %> declaration for the XML
library at the top of your page.  JSTL is made up of several tag
libraries, not just one.

  <%@ taglib prefix="x" uri="http://java.sun.com/jstl/xml"; %>

RE: Where to do the "request.setAttribute"code for iterate, select collection bean

[Siggelkow, Bill]

Actually, "request.getSession().setAttribute("intArray",intArray);" will place the 
object in Session scope, not request scope.

As far as where to load the collection into the request scope -- I would say either do 
in in the Action that forwards to the JSP -- if you have one.   Or use a standard 
jsp:useBean tag in the JSP to make the collection available.

I don't know about the performance implications, but the second way is
helpful if you need to delete whole chunks of the session atomically.

RE: Struts Productivity Survey

[Haseltine, Celeste]

Greg, 

Wow, I don't envy your assignment.  There is one thing that I have learned
over the years as both a developer and project manager, people learn at
different rates, and pick up new skills very differently.

In the case of the people who only know C++, the transition to Java will not
be difficult.  If they have had no exposure to HTML and web development,
then the transition to JSP's will take them a little longer.  I've know some
really good low level C++ programmers who just cannot get the hang of HTML,
much less the tag library underlying struts.  These guys are better suited
for the server side and EJB side of development.

As for the VB programmer, your job is going to much more difficult.  Many of
the VB programmers I have meet over the past 2 years have had no exposure or
training in Object Oriented Programming (OO).  Many have moved to VB from
mainframe jobs that they started back in the 70's and 80's.  For those on
your staff who have had exposure to C++ in college, the move to Java will
probably be easier than for those on your staff you have come from a
mainframe background.

As to Struts, JSP's and the tag libraries.  You are looking at training
these people in ALL three of these concepts/technology.  I would strongly
suggest that you start out your training class in JSP's using the Model 1
concept the first few days, and then introduce Struts and the JSP tag
libraries for the duration of the training course.

In all, my experience in training people in a combination of on the job and
classes has been as follows:

For those with heavy C++ experience, moving to Java/JSP/Servlets/HMTL took
about month before these people were productive.

For those with some exposure to C++ and OO, but no work experience, it took
about 2 months for these people to be productive.

For those with no exposure to C++ and OO (mainframe background), it took
anywhere from 4 months to 9 months before these people were really useful
and productive in the work environment.  A lot depended on the attitude of
the person, and their willingness to learn new programming skills AND new
programming/software concepts, particularly OO.  If you can get over the
hurdle of the OO concepts, then you are 2/3 of the way there.

If you add struts and HTML to the equation, I would add an extra 2 to 4
weeks, before the staff is really productive and useful in the work
environment.  

Keep in mind again that people learn at different rates, and that they learn
in different ways.  The approach you take to exposing and training these
people may not work for the entire group, and you may need to take extra
time and try different approaches with some in the group.

Good luck, this is one assignment that I don't envy you on.

Ok, so let me pose it a different way.  Put yourself in this position:

You're a consultant or an architect who has been tasked with building a
Struts application with 100 screens.  You're actually migrating an
application which was originally written as a fat client app in VB and the
server was written in C++.

You have about 50 developers who know VB and C++ pretty well.  Some of them
know Java/JSP/Servlets very well.  Some of them know it very little.  None
of them know Struts.

Your job is to estimate the cost of getting these folks up to speed on
Struts.  You already have the application design.  THere's going to be a
thin business layer called by the Action classes that will use EJB session
beans to provide application functionality.  Fairly simple.  You have to
train these people to use Struts, create actions and pages, and write the
web-tier business layer.  Somebody else is doing the EJB stuff.

How do you estimate that cost?
How long do you think it will take for these various developers to write
their first business function?
How long to do the next one, etc?

Session Management

[JONATHAN PHILIP HOLLOWAY]

Hi everyone,

I'm wondering about the ways of managing sessions in Struts and wanted
to know out of these two ways which was the better way of doing things:

1. Storing things within the standard servlet session

2. Using a UserWrapper object and storing that within the session.

Is the second way more preformance intensive or not and which is best
practice?

Many thanks,
Jon Holloway.

RE: Getting the full path of the context from within an Action class

[Siggelkow, Bill]

In answer to your first question, you do not have to write your own ClassLoader -- the 
Class object will load the resource using its ClassLoader -- in other words in your 
Action you would have ...

InputStream xmlStream = this.getClass().getResourceAsStream("/resources/xyz.xml");

I don't know the answer to the second question -- I guess it depends on how are you 
planning on parsing the XML.  If you are using Digester I suggest starting with 
http://jakarta.apache.org/commons/digester.html - there are links to the API 
documentation as well as a couple of good online articles.

Cool.

Looks like the thing I'm after. But I have a couple of questions.

Will I have to write the ClassLoader for this?  If so, do you know of any
examples I could have a look at?
Will the fact that the .xml file has recursive tags ( ie I can have
) in the structure cause any major headaches in turning this
into a loaded bean?

RE: Struts Productivity Survey

[Jarnot Voytek Contr AU HQ/SC]

Holy smokes!  You've got 50 people just to do the web layer???  There's 2.5
of us (only one - me - with Java experience) doing a ~75 screens migration
(all layers - but under the constraint to keep the database unchanged as
much as possible) from a 4GL.

Two weeks to get up to speed on struts, then each developer gets 4 weeks to
develop/test 2 screens.  Add documentation and other misc. and you've got
two months - should be more than enough, I'm being conservative - especially
since you're not worried about the EJB tier.
You could cut this down considerably, if you already are a productive struts
developer just implement a few vertical slices and tell the others to copy
what you've done - you just act as 'tech-support' and they'll learn
on-the-fly.

RE: Getting the full path of the context from within an Action class

Simon,
   You should load this resource using the Class object.  Take a look at the following:

Thanks Geir,  that was quite useful to know.

What I am trying to do is read in a .xml file from the classes/resources

have had a look at the ResourceBundle class, but I can't see if that would
be of any use to me.

Any thoughts??

If you ned the path for the WEB-INF, - use a servlet, - which is loaded
before the struts, by configuring it in the WEB.XML.

In the servlet you execute...
public static String directory =
getServletContext().getRealPath("conf");

This returns the physical location of the WEB-INF. You get the location
from the action classes by accessing the servlet' static variable.

Hi,

Which would be the better and more portable solution for getting the
actual path of the API context from within a
org.apache.struts.action.Action class?

I am looking at either using
mapping.getPath()
or
request.getContextPath()

Are either of these going to give me an absolute (ie
C:\xxx\yyy\WEB-INF\) path to the context on the local machine?  Or will
it be a relative URL?

Hi all,

Is there an elegant way using Struts / JSTL tags to tell if any errors are
stored in the ActionErrors object before calling  or even
?  If  is going to display
something, then I want to put a special header on it.  The default
errors.header is insufficient for what I'm doing.

I could write my own tag, but before doing so I just want to make sure I'm
not reinventing the wheel.

RE: turning form parameters into queries

[Siggelkow, Bill]

Heather,
In my opinion, the approach you are taking is not separating out your logic 
appropriately.  In fact, it sounds like your are binding your persistence layer 
(database columns) all the way up to the presentation layer (your action forms).  A 
better approach is to separate the model (data) from the view (presentation).  Let 
your action classes (controller) marshall data from the database to the action forms.  
The BeanUtils classes can ease this activity.

Typically what I have are the following:

ActionForms (or DynaActionForms) that represent the form fields
Actions that get the forms and then create business objects from these forms.
At this point I may pass that business object to a Service layer (like a Manager 
object)
The manager object interacts with a DAO (data access object) that performs the actual 
JDBC stuff.

It really is a question of appropriate assigment of responsibilities.

I suggest you read throught the Struts User Guide as well as check out some of the new 
Struts books that are available.

Subject: turning form parameters into queries


Hi all,

Finding a good method to create SQL queries out of html form parameters 
is something I've struggled with for some time now. Is there a good or 
recommended way of doing this? For that matter, is there a "best 
practice" for making SQL queries in struts?

I use a mysql database backend for my struts application. In the 
browser, the user selects some choices from an html form. My Action 
classes collect the information that the user has chosen out of my form 
bean, pretty standard.

The Action class then sends that info back to a corresponding 
BusinessLogic class (BusinessLogic classes reside in a package that does 
not know about struts or servlets, but correspond roughly one 
BusinessLogic class to one Action class).

The BusinessLogic class needs to take those form parameters and create a 
list of "QueryParam" objects, which are then sent to a "SQLMaker" class 
where they are used to build constraints (the stuff after "WHERE" in the 
query) for SQL queries.

In my BusinessLogic classes, I have this method which gets called by my 
Action class:

public void setQueryParams(String querytype, String fieldname, List 
parameters)


The "QueryParam" class is basically just a bean that I iterate through 
when I build the constraint part of the query. It contains these fields:

protected List _values = null;
protected int _datatype = -1;
protected String _colname = null;
protected String _tablename = null;
protected String _singlevalue = null;

xThere are a couple of problems with this.

First, every BusinessLogic class (and there are many because they 
correspond to Action classes) has the information about the form fields, 
and the database struture info that maps to it, hard-coded. Instead of 
being able to create this method once and for all in a superclass of my 
BusinessLogic classes, I have to rewrite this method for every 
BusinessLogic class, because the subclassed BusinessLogic class knows 
about the Action class that calls its "setQueryParams", and therefore 
what html form fields that Action class will use and how they will be 
mapped. That also means that every time I change a form field name, I 
have to make the change in my BusinessLogic class as well.

Which classes should know what? It seems that either my form bean needs 
to know enough to be able to name form fields after database columns, or 
my business logic classes need to know the name of the html form fields, 
and how they map to database column information, to make the constraints.

Would it make sense to cache a copy of the database struture in the 
struts application, and add all the form field mappings to that? Or is 
there a rule for writing html form fields to go into a database (like, 
"html form fields must be named after database columns").

Somewhere the mapping from form field to database column name, and then 
the addition of other information needed to make the QueryParam (and 
therefore the query), needs to be done, (and it would be nice if the 
method could only appear once in the application), but I'm not sure I 
know where.


Thanks,

Heather M. Buch

Getting the full path of the context from within an Action class

[Simon Kelly]

Hi,

Which would be the better and more portable solution for getting the actual
path of the API context from within a org.apache.struts.action.Action class?

I am looking at either using
mapping.getPath()
or
request.getContextPath()

Are either of these going to give me an absolute (ie C:\xxx\yyy\WEB-INF\)
path to the context on the local machine?  Or will it be a relative URL?

Cheers

Simon

Hi,

Yes, it is possible. In your tiles-config.xml file, you use the

RE: Accessing .properties resources from within an action class.

[Siggelkow, Bill]

Can you give more details on what you are trying to do and why?  Java classes can 
certainly read in property files during runtime.  Read the JavaDocs on the 
java.util.Properties class for details on how to load properties.

Hi,

I have had a look through as much of the examples as I can find on the web
but I have not seen anywhere where the information for a bean is kept in a
resource file and then loaded in using an action class.

Is it possible within struts to do this, or is there another better method,
and does anyone know of an example I could look at?

Hi there,

Have you tried using the SSLext extension for Struts.

I've found it works quite well.

Took a little tweaking but you can use a new type of form called sslext
form. It work like html:form but set the action field to go through the
correct https port.

http://struts.ditlinger.com/

But the main advantage is that you can set action security in
struts-config.

Hello,

I need help figuring out how to make my struts application work with ssl.
I'll try to give a brief overview of what I'm doing:

I invoke the mai.jsp file using https protocol. No problem there. Links off
that page work fine because they are built as "https://somelink...";.

The problem is that when I click on any of the buttons defined inside a
struts form it pops up a dialog box telling me that I'm about to be
redirected to a connection that is not secure.

If I click yes it goes to that page but the url is now
"http://host:443/somelink...";.

I'm sure there is a way to get struts to build the url using the protocol I
came into the application with but I can't figure it out.

Any help would be greatly appreciated!!

Here are some snippets of the main.jsp, struts-config.xml and java files.

RE: Detailed error log - Urgent

Never mind.

The answer is that we test it without tiles, so that the stack trace is
available on the console, sort out the errors and then change the action
path to a tiles definition.

This particular error was a NoClassDefFoundError, actually.

DynaActionBean to choose which bean properties should be reseted (with the 
help os set-property tag in struts-config).

Afaik the boolean properties (assigned to a checkbox) should be reseted to 
false. This was the main reson for extending it and not just simply write an

Multiple apps and class loaders

[Kevin A. Palfreyman]

Hi folks,

I have been having some problems developing multiple similar applications with regards 
to classloaders.

I'm using Tomcat 4.1.18, and struts 1.1b3 (b2 was the same).

What I have discovered is that everything is fine if I package all of the struts Jars 
in each of my applications, but that there are problems if I put the struts jars in 
the tomcat $CATALINA_HOME/shared/lib.

I have two (actually multiple) applications (app1 and app2) that are extremely similar 
and happen to define Form classes which have the same class name (say "FormA").  These 
form classes are used as fields of a DynaActionForm.  

When the struts jars are shared I get classloader issues with symptoms such as:
"Object of type FormA cannot be assigned to variable of type FormA"

Now if I'm following correctly, this is because the first application that tomcat 
discovers is initialised and it's struts-config is read.  The dyna-form is created in 
the parent (shared) class loader, and is using the class definition for FormA as found 
by the child classloader for app1.  Afterwards, app1 can be used successfully.  As 
tomcat continues the initialisation, it reads the config for app2 and attempts to init 
a dyna-form, but finds it already has one so uses that (?).  When I attempt to use 
app2 I get the above error because although the two FormA classes are byte for byte 
identical, they were loaded by different child classloaders.

Is there any way around this problem, other than by including all of the struts jars 
in each of my applications?  What are the minimum jars I could get away with?

Packaged without struts each of my little apps is around 120KB.
Packaged with struts each of my little apps is around 1.5MB.

I know disk space is cheap these days, but I was trying to keep things as lightweight 
as possible for each new application we add to the server.

(thankfully I seem to be able to share my 4MB jacorb corba library rather than 
packaging that with each web-app!)

Is there a way to share the struts libraries so that what I am trying to do will work?

Thanks,

Kev

RE: first action

[Mouratidis, Georg]

to extend the RequestProcessor class

something like this:

public class PcxRequestProcessor extends RequestProcessor
{
  
  protected void processLocale(HttpServletRequest request,
HttpServletResponse response)

you have to have processLocale method.

i use this way to log the acitvities for every request.

hope could help you.

Sounds more like a PlugIn.  Here are the API docs:

You just implement this interface, configure it in your config.xml file
and you're up and running.

hey guys,

what is the best way to implement a startup action that always will
be executed first before any jsp is hit?

thanks

Re: tiles scope

[Cedric Dumoulin]

 Hi,

 The "Cannot find bean org.apache.struts.taglib.html.BEAN in any scope' 
error is usually caused by a struts tag which doesn't find its needed 
bean. For example it can be caused by a  tag. Do you have 
such tag in "c_search_form.jsp" ? I suppose the answer is yes.
 The beans needed by struts tags are set in appropriate context by the 
struts RequestProcessor, which is called automatically when you hit an 
struts action address (*.do).
 To be short, to use a struts html tag, you need to go throw a struts 
action. So, if your "c_search_form.jsp" page have such tag, you need to 
access it throw an associated struts action which then forward to the jsp.
 Then, you specify the action URL in the tiles definition instead of 
the jsp url.

turning form parameters into queries

[Heather Buch]

Hi all,

Finding a good method to create SQL queries out of html form parameters 
is something I've struggled with for some time now. Is there a good or 
recommended way of doing this? For that matter, is there a "best 
practice" for making SQL queries in struts?

I use a mysql database backend for my struts application. In the 
browser, the user selects some choices from an html form. My Action 
classes collect the information that the user has chosen out of my form 
bean, pretty standard.

The Action class then sends that info back to a corresponding 
BusinessLogic class (BusinessLogic classes reside in a package that does 
not know about struts or servlets, but correspond roughly one 
BusinessLogic class to one Action class).

The BusinessLogic class needs to take those form parameters and create a 
list of "QueryParam" objects, which are then sent to a "SQLMaker" class 
where they are used to build constraints (the stuff after "WHERE" in the 
query) for SQL queries.

In my BusinessLogic classes, I have this method which gets called by my 
Action class:

public void setQueryParams(String querytype, String fieldname, List 
parameters)


The "QueryParam" class is basically just a bean that I iterate through 
when I build the constraint part of the query. It contains these fields:

protected List _values = null;
protected int _datatype = -1;
protected String _colname = null;
protected String _tablename = null;
protected String _singlevalue = null;

xThere are a couple of problems with this.

First, every BusinessLogic class (and there are many because they 
correspond to Action classes) has the information about the form fields, 
and the database struture info that maps to it, hard-coded. Instead of 
being able to create this method once and for all in a superclass of my 
BusinessLogic classes, I have to rewrite this method for every 
BusinessLogic class, because the subclassed BusinessLogic class knows 
about the Action class that calls its "setQueryParams", and therefore 
what html form fields that Action class will use and how they will be 
mapped. That also means that every time I change a form field name, I 
have to make the change in my BusinessLogic class as well.

Which classes should know what? It seems that either my form bean needs 
to know enough to be able to name form fields after database columns, or 
my business logic classes need to know the name of the html form fields, 
and how they map to database column information, to make the constraints.

Would it make sense to cache a copy of the database struture in the 
struts application, and add all the form field mappings to that? Or is 
there a rule for writing html form fields to go into a database (like, 
"html form fields must be named after database columns").

Somewhere the mapping from form field to database column name, and then 
the addition of other information needed to make the QueryParam (and 
therefore the query), needs to be done, (and it would be nice if the 
method could only appear once in the application), but I'm not sure I 
know where.


Thanks,

Heather M. Buch

Re: Tiles and tab like style

[Cedric Dumoulin]

 Hi,

 It is possible to use action URLs in the tiles tabs. Simply specify 
the action url as link. Your action's forward should NOT do a redirect.
 If this doesn't work, you have to modify the tabsLayout.jsp. Open 
tabsLayout.jsp and locate the following lines:

 String href = request.getRequestURI() + "?"+parameterName + "=" + index;
   // Don't add request URI prefix , but let the client compute the 
original URL
   // This allows to use a Struts action as page URL, and perform a 
forward.
   // Bug reported by Don Peterkofsky
 //String href = "" + "?"+parameterName + "=" + index;

 Comment the first one and uncomment the latest one. You tabsLayout 
should now work with actions, but no more with jsp or html URL ;-(
  We have to found a better solution for this problem.  If someone as a 
proposal ...

Re: can we have only one tiles_def.xml?

[Cedric Dumoulin]

 Hi,

 Yes, it is possible. In your tiles-config.xml file, you use the 
property keys:

and in your jsp pages you use the key to retrieve the property from the 
application.properties file:

 
 

or :
 
 

 Check tiles tags syntax to know more about

of course not.
 writes an output in the http-stream.

but you want to give the attribute value a value.
so you can define with  a variable and use this variable
to assign to the value-attribut.

i dont know another way, sorry.

RE: html:link tag

[shirishchandra . sakhare]

Easiest way to pass multiple parameters on a html link.


Use the standard anchor tag.


eg:

"/>&salary
nce="/>">

Here the myForm should have indexed getters for empBean

Clas MyForm(){
List empList = new ArrayList();
getEmp(int index){
while(empList.size< index){
empList.add(new EmpBean());
}
return (EmpBean)empList.get(index);
}
}




Very, very ugly but works just fine!

I think the struts way(using map)is not very easy alwqys...

Accessing .properties resources from within an action class.

[Simon Kelly]

Hi,

I have had a look through as much of the examples as I can find on the web
but I have not seen anywhere where the information for a bean is kept in a
resource file and then loaded in using an action class.

Is it possible within struts to do this, or is there another better method,
and does anyone know of an example I could look at?

Regards

Simon
