RE: simple question

[Siggelkow, Bill]

What you are doing should be fine (as long as your collection is not too terribly big).
You use an ActionForm when you want to collect input from the user.

Subject: simple question


Hi all,

I think I have a relative easy question.

I have a J2EE application which has some entitybeans. I want to display 
the values of these entitybeans in my JSP pages (using Struts).
I have made value objects of the entitybeans. 

In my ListAllCategoriesAction.java, I do something like the following:

Collection allCategories = mySessionFacade.getAllCategories();
DisplayBean displayBean = new DisplayBean();
displayBean.setCategories(allCategories);
request.setAttribute("categories", displayBean);
return mapping.findforward( SUCCESS );

As you can see I'm using a special bean (displayBean) to pass the 
categories to my JSP page. In my JSP page I use the  tags 
to iterate through te collection and display the proper information.

Is this a normal / good approach? Or do I have to use ActionForm classes 
for this purpose?

Thanks a lot,

RE: Combining struts and JSTL tags...

[Siggelkow, Bill]

Basically, any of the struts tags that are "struts-aware" were not eliminated from 
Struts-EL -- specifically, the bean:message tag was not eliminated because it 
specifically looks in the application resources as specified in struts-config.  The 
 can be made to look into that bundle but it
does not by default the way the  tag does.  You might want to take a 
look at the 
my presentation http://www.jadecove.com/articles/jstl-and-struts.pdf to the Atlanta 
Struts User Group.

In addition, be sure and read the readme file in the contrib/struts-el folder.

RE: Combining struts and JSTL tags...

[Siggelkow, Bill]

Pady -- generally, there is very little overlap between JSTL and the Struts HTML tags.
There are no JSTL tags that do the work that the Struts html tags do ... that being 
said, I 
encourage you to use the html-el library (basically the Struts html tags which support 
EL)
so you have the full power of EL for the HTML tags as well as the JSTL tags.

Good Luck!

Then in my action that processes the login form I do the following:

public ActionForward execute(...

  // check credentials ...

  String url = ... /// get the originalUrl from the dyna form
  String query = ... /// get the originalQuery from the dyna form

  StringBuffer redirectUrl = new StringBuffer(url);
  if (query != null && !"".equals(query)) redirectUrl.append('?').append(query);

  response.sendRedirect(redirectUrl);

RE: [newbie] Connection Pooling

[Siggelkow, Bill]

Michael, 
  You certainly can write a connection factory class that provides getConnection type 
methods -- I do this all the time to abstract the different ways of doing connection 
pooling -- sometimes I am using DataSources -- other times not.  However, you should 
just use a regular class for this that is *not* stored in the session -- perhaps even 
a singleton or utility class.  Unless the connection pool configuration is 
user-specific I see no reason to store this object in the session.

Let me know if this makes sense to you or if I do not fully understand your

Ups..I didn't express corectly. I mean I keep in the session context 
  not certain connection but object which provides connection pooling. I 
have i.e. static method getConnection() which returns next connection 
from the pool.

RE: [newbie] Connection Pooling

[Siggelkow, Bill]

Andre ... this is not connection pooling -- but rather keeping a connection open.
Yes it can be done ... however, HTTP is not a reliable connection and there is a good 
chance that your connection will get left open.

However, it is time consuming to always have to open/close connections -- hence, the 
answer is connection pooling.  If you are using a J2EE container that supports 
connection pooling (most do) you can use the connectors mechanisms for defining the 
connection pool.  If not, you can use the Struts data-source elements which use the 
Commons DBCP package.

Incorrect assumption with logic:present role attribute

[Siggelkow, Bill]

I have an app where I have created my own RequestProcessor to override the 
processRoles functionality.  Specifically, my roles take into account certain session 
information.  This works as expected and properly handles the 'roles' attribute in my 
action mappings.  However, I naievly (sp?) made the assumption that the role attribute 
of the logic:present tag would use this same functionality -- but it doesn't.  It 
seems that the  only does a 
request.isUserInRole("somerole") -- it seems to me that if I override the processing 
of roles it should affect both the action mappings as well as the logic tags (and any 
other Struts tags) that use the 'role' attribute.  Has this been considered?

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

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.

Will the fact that the .xml file has recursive tags ( ie I can have

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.

It looks like JBoss has already loaded an old Digester or you have an old copy of

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.

Thanks,

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

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?

This is not a Struts question ... however, if you want a modal dialog -- that is, one 
where the user has to respond before continuing -- you need to use JavaScript.

I am not trying to be critical but it sounds like you need to spend a little time 
learning the capabilities of HTML and browsers -- I suggest O'Reilly's "HTML & XHTML - 
The Definitive Guide" -- also, you can find many tutorials of HTML online.  Also, you 
will probably want to take a look at "JavaScript - The Definitive Guide" as well.

V,
When you replied "Yes" below you seemed to indicate HTML provided some sort of 
built-in ability for multi-row selection in a table (not in a "select" control) -- I 
do not believe that HTML provides such -- however, you can indicate of rows in a table 
using a variety of input controls (checkbox, select).

In my experience I have used a checkboxes for each row to indicate selection and in 
some cases provide a "Select All" or "Select None" type of control.

RE: Call Struts Action from JS

[Siggelkow, Bill]

Also, I meant to say that the error from IE is saying that in its DOM it doesn't have 
the property you are referring to.  If the formObject is actually the form itself then 
eliminate the 'form' property ... in other words, you would have:

formObject.action="<%=request.getContextPath()%>/getAccounts.do";
formObject.submit();

What type of object is formObject?  That is, how are you calling this function (e.g. 
from onclick? or some other event handler).

If 'formObject' is actually the 'document' then you would do something like ...

  formObject.forms[0].action="<%=request.getContextPath()%>/getAccounts.do";
  formObject.forms[0].submit();

or if the form were named 'myForm' you could use ...

  formObject.myForm.action="<%=request.getContextPath()%>/getAccounts.do";
  formObject.myForm.submit();

Also, I am curious as to why you are needing to set the action via JavaScript when it 
doesn't seem like it is dynamic?  Even if you submit using the submit() method of Form 
it will still use the action that is specified for the form tag.

Another thing to keep in mind is that calling 'submit()' will not invoke any onsubmit 
event handlers if you have them.  In general, I don't like using the 'submit()' method 
but sometimes it is unavoidable.

I'm currently on a project that has released a production web site using

I'm now trying to migrate to V1.1-anything. We're using weblogic V6.1, with
jdk1.3.1,

I downloaded V1.1-b2 and b3, thought I performed all the installation steps,
upgraded our 
struts-config file to the 1.1 dtd, and tried both our application and EVEN
the sample from 
the download (in 'mydomain' in weblogic), and I keep getting the exception

Is this a parser issue? I downloaded and used xerces V2.2.1.   Thanks in

RE: How to pass control between two struts web apps deployed on the same app server.

[Siggelkow, Bill]

The servlet spec disallows forwarding between web applications.  The second app does 
not have access to the session.  If you need a shared session, you might want to 
consider using Struts modules to subdivide your web application.
If you are looking to implement a single-sign-on -- they are ways of doing this but it 
varies by app server.
I know that Tomcat has an approach for this.

Hello,

We have two struts web application deployed on one app server. One with
context at / and other one with context app2/ . How can I use jsp:forward to
transfer control to second app2 from first app. Also when I do this would I
have access to the session that I create in the first app. And would I be
able to use checkLogon kind of tag in the second app, if not what do I need
to change ?

RE: Struts equivalent of if...else (newbie)

[Siggelkow, Bill]

The Struts logic tags do not provide if...then...else -- you can certainly simulate 
that by using the "not" versions of the tags -- the if-then-else logic can be 
implemented like the following:


  'if' markup here


  'else' markup here


The decision was made (and I believe the appropriate decision) that the tags should be 
kept as generic and simple as possible ... there are if-then-else tags available from 
other parties but I would stick with the basic struts tags and/or JSTL for this kind 
of stuff.

And I tried to use logic with local variables, it worked. Thanks for

Struts does not convert Strings to dates -- you neecx to do this in your ActionForm --

setDateDisplay(String d)

that perform the conversion to the internal Date type.

Thanks, but I think there will be a problem with the bean:define since the
jsp 1.1 spec does not allow you to use the same bean name more than once in
a single page (which is what we would be doing in an iterate tag.)  Unless
I'm misinterpreting.

RE: Iterate Index Evaluation

[Siggelkow, Bill]

Strike that ... reverse it!  I was able to use the bean:define as follows:


  
  
even markup here
  
  
odd markup here
  


Give it a try!  The expression is still a little wicked but not as evil as the 
scriptlet.

Er ... I think you may be right ... I know it can be done using scriptlet for example:


  <% if ((index % 2) == 0) {%>
even row markup here
  <% } else { %>
odd row markup here
  <% } %>


But we all know how evil this is!

Thanks, but I think there will be a problem with the bean:define since the
jsp 1.1 spec does not allow you to use the same bean name more than once in
a single page (which is what we would be doing in an iterate tag.)  Unless
I'm misinterpreting.

RE: Re[6]: [OT] some log4j problems using RollingFileAppender not creati ng a backup file

[Siggelkow, Bill]

Hmmm ... I was able to get it working on my set-up -- that is, it created the backup 
files when the file reached 2K ...


Struts 1.1b2
WLS 6.1 sp4
Log4J 1.2.6
NT 4


One wierd thing I noticed was that it seemed like WLS only picked up my new 
log4j.properties when I hot deployed my webapp -- but not when I restarted WLS -- WLS 
has always been flakely when it comes to deployment.

I suggest you look at trying Log4j 1.2.6 or see if using the DailyRollingFileAppender 
might work.

BTW, my appender looks like:

log4j.appender.RollingFile=org.apache.log4j.RollingFileAppender
log4j.appender.RollingFile.File=mirage-log-test.txt
log4j.appender.RollingFile.MaxFileSize=2KB
log4j.appender.RollingFile.MaxBackupIndex=5
log4j.appender.RollingFile.layout=org.apache.log4j.PatternLayout

Even with everything closed except the web browser, the archive file
is not being created. It does seem to consistently start over though
with a blank log file when it reaches 2K- so I know it's understanding
it needs to do something when it hits 2K. It's just the archived copy
that is not being created.

Yes exactly. It doesn't create the archive(backup) copy.

(And actually it doesn't 'always' seem to even create a new
backoffice.log. Hard to explain on this later point as it doesn't seem
consistent. According to that one link on the log4j others seem to
have similar problems on win2k so maybe it's just a windows thing-
although I swear it used to work with the old log4j jar and using
Cateogry as opposed to Logger).

It is my understanding that any page that you include cannot be outside of the current

I have a need to display a page via , 
but the trick is the page is NOT contained in the webapp. It is a page 
that is external to the webapp but still on the same server.

I have recently switched from using iPlanet v6 to Tomcat v4.1.18 as my 
web server/container for various reasons, but it worked under iPlanet 
and does not under Tomcat. If I include the external page in my webapp 
it works on Tomcat. Is this the normal feature of tiles? Can tiles only 
work with files that reside in the webapp -or- am I just not calling it 
correctly.

On my server I have two webapps one is called staging. I'm converting an 
existing site to struts with a whole new look and feel and the staging 
area is a place where developers can make some quick changes to an 
existing page without having to reload the main webapp over and over 
again. They will eventually be part of the main webapp, but now they are 
technically external to my main webapp. If I just use the full URL in 
the browser like http://myserver/staging/some-page.html the page views 
as expected, but if I try to display it from my main webapp via 
 I just get a blank screen.

Man, I'm stumped even more by all of this:) ... I tried having a
log file in all different places and with all different path set
ups. Behavior seems to always be the same.

The only small oddity I've found is that if I let the log fill up
on it's own up to capacity (2K) it will just the same log file
over again when it gets too big. However if I manually cut and
past to fill up the file to say 5K and then use the app which will
write to the log file it doesn't start the file over and keeps
writing to it (until I restart the server). Neither scenario
creates a backup though so I'm still stuck there. I'm going nuts
here.

You sure this log4j properties file looks ok? (on this last
attempt I took out all paths and it writes the log file right in
the bin folder).

log4j.rootCategory=ERROR, rolling
log4j.logger.com.adp=DEBUG, rolling
log4j.logger.corporate=DEBUG, rolling

log4j.appender.rolling.layout.ConversionPattern=%d{MM/dd/yy hh:mm:ss a } %-5p %c -

Any other ideas? Thanks for the help so far.

I know this isn't a struts question, but the log4j list seems pretty
dead that I posted this to and I've searched and searched for some
answers and I'm desperate now:). Maybe someone else using log4j in
their struts apps has run into this problem...

I'm using log4j 1.2.7jar and Tomcat 4.0.6 on w2K.

I can not seem to successfully get the RollingFileAppender to back up
the file after it gets to a certain size. I saw this post in the
archives but it didn't seem to provide a solution:
http://www.mail-archive.com/log4j-user@jakarta.apache.org/msg06397.html

My properties file looks like:

log4j.rootCategory=ERROR, rolling
log4j.logger.com.adp=DEBUG, rolling
log4j.logger.corporate=DEBUG, rolling

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n
 
log4j.appender.rolling=org.apache.log4j.RollingFileAppender
log4j.appender.rolling.File=C:\\jakarta-tomcat-4.0.6\\logs\\backoffice.log
log4j.appender.rolling.MaxFileSize=2KB
log4j.appender.rolling.MaxBackupIndex=5
log4j.appender.rolling.layout=org.apache.log4j.PatternLayout
log4j.appender.rolling.layout.ConversionPattern=%d{MM/dd/yy hh:mm:ss a } %-5p %c - %m%n

I'm using 2KB for max backup size for testing, but it never seems to
create a backup file (backoffice.log.1 etc). It does end up resetting
the  backoffice.log when I restart the server but normally without
bouncing the log just fills up past 2K. I really would love to get
this backup working otherwise I'll probably have to reinvent the wheel
and create my own FileIO stuff to do the logging.

Any help would be greatly appreciated with this.

Thanks,

My understanding of this is that it will call getUsers() on the

Do I need to define a bean somewhere (in some XML file?) for the user
objects contained within the collection or something?  The collection
contains UserView objects that /do/, in fact, have a getEmail() method, so
I can't figure out why this won't work.

RE: How to set formbean properties without asking the user

[Siggelkow, Bill]

Can you provide more details?  When you are dealing with forms, the basic types are 
either String or booleans.  Perhaps what you want to do is best handled in your Action 
that processes the form.  It sounds like you need to make an object available in let's 
say the request scope and then have that object be used along with the form in the 
Action.  The thing is forms were meant to work with user input -- it may prove 
difficult to try and use it in a different fashion.

My 2 cents.

RE: Access external file from web application

[Siggelkow, Bill]

I built an application on WLS 6.1 using Struts 1.0 that supported display of 
user-uploaded content.  Several keys to this were:

1) I had to deploy the web app in exploded format
2) If WLS was run in Production Mode I had to call a little runtime script that 
deployed (refreshed) the new content (otherwise, it would not be available)
3) I stored the content in a context-relative folder -- though, I used a database 
table to hold content metadata which included the content mime type, the 
context-relative URL, and user-supplied title and description, and system-generated 
file name.
4) I used the Struts support for upload to perform the upload.

Let me know if this helps -- If you have specific questions e-mail me directly as this 
is a bit OT for Struts.

RE: reset doesn't work well

[Siggelkow, Bill]

Doug, I think you are misreading or misinformed about both the reset button and the 
reset method.  The "reset" button does a client-side reset of the form -- there is no 
interaction with the server.

The reset method is called by the ActionServlet when a form is reused -- but I do not 
think that it is called on when validate returns false -- in fact, I would think that 
you would not want it called so that the user does not "lose" all of their previous 
input.

Hi, Bill:
Thank you for reply.
The ActionForm api says:

   " public void reset(ActionMapping mapping,  
javax.servlet.http.HttpServletRequest request)

   Reset all bean properties to their default state. This method is called before the 
properties are repopulated by the controller servlet. 
The default implementation does nothing. Subclasses should override this method to 
reset all bean properties to default values. "

   
 

   
I have overitten the reset method to reset both amount and password to null. From my 
understanding, whenever user clicks reset button, it will call the reset method, 
therefore, all the fields should be cleared.

   
Please correct me if I am wrong.

Hi,

I would like to know whether the following is possible to implement with
Struts.

I display a form for creating, say, a Service. The user fills in a form.
When the form is submitted, the Validator performs the validations with
no errors. Now the control comes to the execute method. In this method,
I find that the Service Name is already present in DB. Now I need to
display the "input form" indicating along side the field that "this
Service already exists, give a different name".

Although it seems possible, the doubt I have is as follows. The input
form might have been generated based on a complex s performed
in the JSP. Now when Action encounters an error, will it be able to
display the input form in "exactly the same" state? Which means that if
the input form contains a lot of fields with specific values, do I see
the same values when it is displayed again with some errors?

Thanks for your time.

RE: mapping to domain objects

[Siggelkow, Bill]

One option is to have your form implement an a domain (business) object interface.  
For example, you would have Customer interface that would have the get/setFoo methods 
and the form would implement get/setFoo (for the business interface) and 
get/setFooString (for presentation) -- in this way you can use the form both as a 
translation object as well as a transfer (value) object -- that is, internally, 
setFooString() would translate the string into the business foo type.

Subject: mapping to domain objects


Hi,

I had previously been using struts 1.0, and have started a project using
1.1 - in 1.0 the method I used to map forms to domain objects (By domain
object I mean value object - representing the problem domain e.g. User,
Account, Bank etc.) was to create an action form with the domain object as
an attribute.  I would then create special setters and getters in the domain
object to handle the different types coming in as Strings - e.g.

public void setDateString(String date);
pubic String getDateString();

and also use the nested library to traverse the domain hierarchy (e.g. loop
through a list of accounts in a bank domain object).

Basically I don't like this method because it corrupts all of the domain
objects with methods that are specifically for the presentation layer, and I
couldn't easily validate the incoming values without creating an ActionError
list in the domain object and pulling this out when I hit the validator.
Never mind - lesson learned.  I really did like the nested tags though.

Now that struts 1.1 is on the table I am wondering what I can do to make
this better.  I like the DynaValidator but this appears to only be useful
for static forms (ones that aren't changing depending on the data).

I've been looking at the decalrative exception structure - but I can't quite
make out whether these exceptions can only be caught from the Action or also
from the form associated with the action.  Thats probably one for me to
check out although I can't see it mentioned anywhere.  I was thinking this
might be a good way to handle the problem of domain validating by doign the
validation in the setters and throwing exceptions rather than doing it in
the validate() method.

The only other method I can really see is to produce a wrapper around my
domain objects specifically for the purpose of providing String
setter/getter interfaces so I don't get number format errors on my setters
trying to convert to the actual attribute types.

I guess the main aim of this post was to see if there is a way of doing this
that anybody has found elegant.  I am probably missing something - but what
I am really looking for is a way to map form strings to domain attribute
types directly trapping any format errors in the process.  Any pointers?
Thanks in advance

Doug, the servlet container is responsible for invalidating the session based on the

Greetings:

I am using struts1.1b2 to implement a web application. I have a question regarding to 
implementing session timeout. When session is invalidated, user who has logged in the 
system should be forwarded to login page. I am not clear about the followings, and 
hope someone can help me out.

1. Who will invalidate the session when timeout? Servlet container will do it 
automatically?

2. Should I use request.getSession(false) to check if session is timeout? If so, that 
means for every request, it will check if session is invaildate. Will it cause 
performance problem? If not, which methods should I call to check it?

3. If I should use request.getSession(false) to check session timeout, where should I 
write the code? Should I write the code in every action class?

4. There are many methods related to session, such as getCreationTime, 
getLastAccessedTime,..Where and how should I use them in the implementation?

5.From my understanding, I can set timeout in web.xml or use setMaxInactiveIterval(int 
..). Usually which way should be use?

6. After user login, I want to forward the user to the page where he was when session 
timeout. Where should I save the information(with the information, I know where I 
should forward the user to)?

I searched the archive. However, it seems that I can't find the specific info.

Your help is highly appreicated.

maxRecords: Number of records to display per page
rowPosition:index number of the first row on this page

I also have the value totalRecords, which is passed into the request object
in my action class.  It is not a property of the form bean.

I need to do something like:





Where the property would actually need to be an expression like rowPosition

Help with understanding validation and reset

[Siggelkow, Bill]

Okay, 
I do not think I understand the contract of the ActionForm validate
method.  The problem I am having is that I appear to
lose some a data value when I return to an input page after I return
validation errors.  Specifically, I have a Date property called 'postDate'
... the value of this property is displayed on the page (but NOT in a
form-field).  The date displays the first time I enter the page (after my
action that populates the form) but this property is blank (null) when I
return to the form (set as the 'input' attribute in the struts-config) to
display validation  errors.

BTW, I have set the form in the request scope in the Action mapping ...
should I be using a different scope?

Do I need to represent this date property as a hidden field on my form?  I
think that is my problem.

Ahhh - I grok!  The action servlet creates a new form when I press Submit --
this form does not have the postDate property set.

RE: Problem with bean:define? Issue with Date fields

[Siggelkow, Bill]

Well ... if you have been following this thread I thought I had a problem
with the 'define' tag ... actually my problem was not with the define tag.

The problem was I did not include a 'hidden' field to hold a date property
in my form bean.

Once I did this I was able to use the define as I originally intended.

It was a slight inconvenience to realize that I had to provide a special
'get/setDateAsString' type methods to hold the render/transform the date
value.

It would be nice if in the future, the Struts tags supported some automatic
conversion of Date objects.

RE: Invalidate and container authentication in multi-app environment

[Siggelkow, Bill]

I know in WLS 6, all web apps use the same cookie name, JSESSIONID to hold
the session ID (and thus facilitate single-sign-on). In WLS 6, you can
specify a different cookie name in the weblogic.xml file for that web app if
you don't want the single-sign on behavior (which I think is what you are
seeing).  I suggest you look at the stuff on the edocs.bea.com site or
search the BEA newsgroups if you need further info.

Subject: Invalidate and container authentication in multi-app
environment


Hi,

I have been researching the archives trying to resolve an issue.
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg10294.html
http://www.mail-archive.com/struts-user@jakarta.apache.org/msg14538.html

These threads describe my situation pretty closely (although not exactly) 
and the solutions provided have not worked for me.

I will describe the problem here again and hope that someone out there may 
be able to offer advice.

I am attempting to implement a Logout action which will log out the user and

forward them back to the main page of the application.  The main page action

itself is secure and should prompt for authentication before allowing the 
page to be viewed.
In the logout action:
a) invalidate the session
b) forward to the application's main page (redirect=true)

Now, normally if I just log into this application (let's call it Application

A), do stuff, and then log out, the logout is successful and the login page 
appears as expected.

Now, here's the twist.  If I log into another application (let's call it 
Application B) and just change the url (without logging out) to point to 
Application A, log in and then try to log out of Application A, then it does

not log out.  It behaves as though the user was still authenticated.  If I 
log out of Application B before changing the url to point to Application A 
then I am able to log out successfully.

Let's review the scenarios.

Scenario A
- bring up new browser window
- log into 'Application A'
- do stuff in 'Application A'
- log out
- result:  logs out properly.

Scenario B
- bring up new browser window
- log into 'Application B'
- change url, without logging out of 'Application B', to 'Application A'
- log into 'Application A'
- do stuff in 'Application A'
- log out of 'Application A'
- result:  does not log out properly, it should prompt for authentication 
before showing main page, but does not.

Scenario C
- bring up new browser window
- log into 'Application B'
- log out of 'Application B'
- change url to 'Application A'
- log into 'Application A'
- do stuff (ie. go to add page)
- log out of 'Application A'
- result:  logs out properly.


I guess if the users were properly disciplined to log out of their 
application before moving on to another application then this would never be

a problem...but... the world is not so perfect.

Any ideas?  Has anyone encountered this before.

I am running Weblogic 5.1 sp10 using Struts 1.0 release.


Thanks,
Michelle

RE: Form Bean with a Mutliselect box - Followup Question

[Siggelkow, Bill]

If you want to do something on the same form with the selected IDs without
hitting the Submit button then you can use the IDs with some javascript ... 

However, if you are talking about processing the form after Submit, you can
do anything with the values.

For example, in my case, I have a wizard-style interface where in the first
screen the user picks multiple IDs, then in the second screen, details about
each of the selected IDs is displayed in a table.  To set up the second
screen, I took each ID and used those IDs to access detail data out of a
directory server (of course, this data could come thru JDBC, EJB, anywhere).

RE: How to list options in order?

[Siggelkow, Bill]

I see two primary options ...
(1) use a TreeMap instead of a Hashtable 
However, to me this be unnecessary if the sorting is purely for presentation
purposes, or
(2) Create a JavaBean that holds two lists ... one for the option values and
one for the option labels ... sorted according to the labels.

I have done this on numerous occasions where I have a collection of things
that contain IDs for use as values and then names for use as labels ...
Basically, I first sort the collection according to the field I want
(typically, I do this using a Comparator) then I create two lists one for
the values and one for the labels.

Of course, if you are accessing the data from a database and can do the
sorting there it is preferable then sorting in the middle tier.

BTW, I am using Struts 1.0 -- there may be features in the nightly build
that make this easier.

How do you set the values from scripting variables or the results of tag

version of JSP?

E.g.


Simply puts the above string directly in the output (unsurprisingly - I was
getting desperate trying that). If I try to use  instead the
page doesn't compile as the resulting fragment is not valid XML.

Apologies for the basic question - this is driving me nuts!!

Hi all

Can anyone help with these problem?

Problem 1

I would like to be able to use the Tomcat JDBCRealm features in concert with
struts - the problem is this - how can I provide a hypertext link in an
e-mail I send to users that will allow users to log into my struts webapp
without having to manually type the j_username and j_password into the web
browser.  I'm sure that this should be simple but the solution eludes me.  I
would like to use the JDBCRealm features because of the good facilities this
provides for controlled access to privileged data.

Here is the form I'm using:



userID
Password





Problem 2

Once authenticated into the JDBCRealm, how can I then 'automatically' pass
the user into my struts webapp - extracting username (perhaps remoteUser
info) as I go?

You can force a refresh with JavaScript like ...

Then you can call this function if the pic has been updated.

Hello.  First, thanks for all of the great advice. 
I've decided to store the files in the file system and
have written a little method that creates a sub-folder
based on the month/year that the user registered.  I'm
storing pictures with the same name as the username in
this directory.  The only thing I'm storing in the
database is the file type (gif, jpg).  Another method
takes the username, looks up the sub path (appends it
to a base path read from a config file), grabs the
file type and returns the HTML  tag that shows
the pic as either a thumbnail or fullsize.  My next
problem is in updating this picture.  I have an update
page that calls the 'showPic' method so users can see
what pic is current, then allows them to enter a path
to a new pic if they want to change their picture. 
Say I enter a new picture and submit.  The new picture
overwrites the old one, and in the next page (which
shows all the users' properties), I'm calling the same
'showPic' method to show the current pic (along with
other properties).  The picure on the file system HAS
been changed - my problem is that the old pic has been
cached somewhere and is displaying on the properties
page.  If I refresh the page, the new pic is
displayed.  Where is this cached?  How can I force a
reload, or force the page to refresh?  
I'm new to all this, so I welcome comments on my
strategy - I'm aware that it probably isn't the best
solution - I'm on a tight deadline and am more
concerned with getting things working.  This project
is a learning experience.  How can I fix my refresh
problem?  Thanks for your time, Andrew Timm

Is it possible to set a default bean for logic tags like it is for form tags
so that they don't have to be named in each logic tag?

If I don't specify the "name" in an  tag, the "name" from the
parent form and its corresponding action tag will be used.  For example, in
the below  tag, fooForm will be used as the "name" from the
parent form since the "name" is not specified.

 
 ...
 

 

Is there a way to do this with logic tags?  I have lots of redundant logic
tags that need to use different beans, but since I have to have a different
value for the "name" on all of them, there's no clean way to reuse the JSP.

Thanks,
Mike

URL? (Without using scriptlets?)

I effectively want to do: ">



but can't do nested tags.

How do I dynamically populate the content of the href attribute?

Help please!

Thanks

RE: Logout Action

[Siggelkow, Bill]

I am using form-based authentication on WLS 6.1 sp1 and do not see this
behavior.

Subject: Logout Action


Hi all and thanks in advance!

I have a link that I map to a logout.do action. In this action it
basically cleans up the resources and so forth.
It clears the objects that I loaded in to the session. It then
invalidates the session and then sends the user to a new page.
So here is the problem. 

The first time the user goes through the application every thing works
as it should.
Then if the user goes back to the login page(with out closing the
browser) and goes through the app again. Then clicks on the logout link
the user is forwarded to the logout page but the log out action does not
seemed to be called. I checked the session objects in login section and
they are definitely present when they shouldn't be.
By the way this does not happen if the user kills the browser and then
re-opens.

Any ideas on what could be causing this???

RE: check for null collection

The way I do it is to create a variable using the bean:size tag that

Then I check if that value is 0 as follows ... (in addition you might want
to also check if the collection is present as you are doing)

Hello,

I am relatively new to Struts and am encountering a problem with the
struts-config.xml file.  I have set up a global-forwards like below:



Then I set up an action like below:




Then I wrote the following index.jsp page:

<%@ page language="java" %>
<%@ taglib uri="/tags/struts-logic" prefix="logic" %>


Now when I hit index.jsp, I receive a blank page from Tomcat 4.0.  If I
review the Tomcat logs, I see that it encountered a 404, but why?  I
thought
it should have found the action "/Menu" and forward it to the menu.jsp.

I am sure this is something simple, but I can't seem to see what wrong with
the above.  This is running under Struts 1.0 and Tomcat 4.0.

Any assistance is greatly appreciated.

Seems like my struts installation doesn't work anymore as expected. All my
forms do not have .do added to the end of action url anymore. It's
interesting because html:links does work. What can cause this behavior? I
did not do anything except updated my own jar-package.

RE: problems mapping multiple ActionServlets

[Siggelkow, Bill]

I had the same question last week (and for some reason did not get any
response from
the mailing list?)  ... anyway, it seems to me that Struts really does not
handle multiple
servlet mappings for the ActionServlet.  When using extension mappings,
Struts finds the action mapping to use by stripping off the ".do", or any
other extension, and using that as the path for determining the action
mapping.  I was trying to do a similar thing where *.do was the authorized
stuff, and *.go was to be the anonymous stuff ... it ended up that the
generated URLs always became *.go!  I think it is simply using the "last"
mapping specified.

My plan is to only use one extension mapping for my ActionServlet and come
up with a different mechanism for applying my security constraints.
Possibly by a vitual path where I would have 
*.do -> as my ActionServlet servlet mapping
Then I would use ...
/protected/*.do for restricted pages ...
Then I could set up a security constraint for "/protected/*"

My 2 cents ...

This might be more appropriate for the Tomcat user
list, but I'll try anyway.  I'm using Tomcat 3.2.2
and trying to map multiple ActionServlets in
web.xml.  I have a  for "*.do"
which I execute for the form action "search.do",
and everything works fine when this is the only
 in web.xml.  But as soon as I
add another  for "*.authDo", when
I try to execute "search.do", "search.authDo" is
called (it even appears in the URL), which I don't
understand since I don't call "search.authDo" from
anywhere in my page (or anywhere on the site).  If
I the change to added mapping to any name, like
"*.anything", "search.anything" is called . 

The pertinent code is below.  Many advanced
thanks.

multiple servlet mappings for action servlet?

[Siggelkow, Bill]

What are the implications if I have multiple URL mappings for my
ActionServlet?  Specifically, say I configure '*.do' and '*.go' as mappings.
I may want to do this for security reasons, let's say, where *.do is for
security-constrained web resources and *.go is for non-security constrained
resources.  Specifically, what should be the behavior if I use the 'link'
tag?   Is there a better way of doing this?  I ran into this situation where
I created a single form for handling user registration as well as user
profile editing.  I pass in a request parameter that identifies if it is
"register" or "edit".  The problem is that I had initially set up *.do as a
security constrained web resource collection.  However, then I couldn't
access the URL for registering, so I created the *.go mapping ... then I
created an Register action that simply included the edit action ...

RE: URI is null error on ActionForward

[Siggelkow, Bill]

Use 'mapping.findForward("success")' instead of creating a new ActionForward
as the return value of your perform method.
This will use the local forward defined for your action, or if not
specified,
will try and find a global forward named "success".
