Re: struts and OSWorkflow
The library works with struts 1.1, but the following modifications need to be done to the test application: 1. In web.xml, the init-parameter mapping is not used anymore. Instead, you must add className=com.livinglogic.struts.workflow.ApplicationMapping in every action in struts-config.xml. 2. Also, the *common.jar files needed in struts 1.1 must be present in the .war deployed with the sample application. Aside from this, there is a minor bug in the web.xml file of the test application that causes the server to choke, if it parses web.xml with a validating parser: The second servlet-mapping section has to be placed directly beneath the first one. I will soon put a bugfix release on the web page. --- Matthias Frederic Laub wrote: Your Struts Workflow Extension seems very interesting but does it does work with struts 1.1?

Let's look at an example: The workflow extension can guarantee that the user traverses an application by executing Action A before executing Action B. This way you don't need to check in Action B, if the data that Action A has put into the session is already available, because you can rely on the fact that Action B can only be executed, if Action A has been executed before. I. e. you can design your web application more like a classical GUI application where you have modal dialogs and where you can be perfectly sure, that nobody can send a request you do never expect at this point in time.

Status of Struts integration with container managed security and alternatives
I've recently played with the container managed security of J2EE (using Tomcat) and the attempt at integrating it into Struts 1.1. I see that a roles attribute has been added to the action tag in the struts config XML file. The problem is with tag is that it doesn't work. I posted a couple questions about this and didn't get much of a response so my impression is no one is using this feature. So my question is any work being done on this? And what are the alternatives? I know I can protect the actions using the normal J2EE container managed security mechanism. The only problem I see with that is that I now have to keep the actions in my struts config xml file in sync with the actions in my web.xml file. Are there any other solutions?

tag in the struts config XML file. The problem is with tag is that it doesn't work. I posted a couple questions about A slight clarification I meant to add. The roles attribute will prevent the user from using the action if the user doesn't belong to the roles specified. However that alone is not enough to be useful. I don't think anyone can use this feature the way it is currently functioning. If the user hasn't authenticated the user is given an error page. From Craig's comments, it doesn't seem possible to redirect the user to a login page. To accomplish this, the security must be specified in the web.xml file.

RE: Problem with Struts 1.1b2 and Weblogic
Hi, I upgraded to Struts 1.1b2 from an earlier version of Struts 1.1 and Weblogic gives an error at startup. Not sure if thats to do with Struts, Weblogic or both. It's definitely not to do with struts. The 1.1b2 struts-example.war is deployable with WLS 7.0 without any problem. Weblogic wasnt giving any problem with the earlier version of 1.1 ... could not be handled by the ClassLoader with classpath C:\bea\user_projects\mydomain\applications\mediamania;C:\bea\user_pr oject. I have got this error message with an earlier struts version on WLS 7.0. I could fix this error, with undeploying the application and redeploy it under a new name. Be careful, if you kill the WLS process it will remain some jar files in the .wlnotdelete directory, and I think this is the main reason for the classpath problem. One more question -- In the error message classpaths are printed on the console like commons-digester21941.jar, commons-pool21944.jar and so on Why is the number appended to the end? The Weblogic server will copy all the jar files from the WEB-INF/lib directory where you deployed from, into some internal directory (.wlnotdelete). But this copy is not only a simple copy. The WLS rename the file (some numbers appended at the end), and looks into the jar files, and will modify the META-INF/MANIFEST.MF if it contains any Class-Path entry. He needs it because the changed file names. Look the original MANIFEST.MF (from struts.jar) and the other one, found in the struts52807.jar: Original: Class-Path: commons-beanutils.jar commons-collections.jar commons-dbcp .jar commons-digester.jar commons-logging.jar commons-pool.jar common s-services.jar commons-validator.jar jakarta-oro.jar Modified: - Class-Path: commons-beanutils52801.jar;commons-collections52812.jar Note that the WLS's class-path is shorter, and uses ; as separator (on my NT machine) Another interesting thing is that WLS makes 2 copies of the jar files. The first one (struts52793.jar) has no file attributes set, but the second one (struts52807.jar) is archive. Only the second one is used in the classpath.

Re: Message Resources Placement
speculation reason=I haven't used eclipse w/ sysdeo plugin I suspect the problem is that the plugin adds struts.jar to the system (ie. tomcat's) classpath. So, all Struts' classes don't see WEB-INF/classes. /speculation At 06:05 am 26-08-2002, you wrote: I think I've solved it!!! Short story: add your /classes folder to tomcat's classpath. Long story below (gurus please see questions at bottom): I'm using struts 1.0.2, tomcat 4.0.4, and eclipse with the sysdeo tomcat plugin as a development environment. The way struts finds/loads the messages file is by using the classloader and the getResourceAsStream() method. That means the messages file must be on the runtime classpath for the classloader to be able to see it. Now, I had some struts projects that worked and some new ones that couldn't use the bean:message tag without throwing the error I described previously. All I did was (through eclipse) add my new project to tomcat's classpath. I'm not sure what the plugin does behind the scenes but I imagine it starts tomcat with something like: java tomcat -cp /myapp/classes Can someone confirm that this is what is going on? When I deploy my app outside of my development environment will I need to start tomcat with this type of statement? I assumed webapps were automatically on the containers runtime classpath, is that wrong? Dave Hi. I'm having the exact same problem, so I can't help you. But I am interested in the solution! If you solve it, please let me know. Here's my previous (unanswered) post, in case you're interested: I'm using v. 1.02 and Sun J2EE SDK 1.3.1 (Tomcat) and have been trying to get Struts to start up without much luck because of ApplicationResources.properties. Currently, I have extended ActionServlet to spy on what init() is doing, and I see the log message: Loading application resources from resource ApplicationResources.properties Looks good! The file is in the same directory as the new servlet (/WEB-INF/classes) so it can't be a path problem. However, my first action (init.do) simply loads a JSP that includes the code: logic:notPresent name=org.apache.struts.action.MESSAGE scope=application font color=red ERROR: Application resources not loaded -- check servlet container logs for error messages. /font /logic:notPresent Which does its job and displays this error message. Why? I even tried: % out.println(config file = + config.getInitParameter(application)); % and it printed config file = null. Also, if I try to display a message then it gives a message with key XXX not found, as I would expect, given the above behavior. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] _ Chat with friends online, try MSN Messenger: http://messenger.msn.com -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- John Yu Scioworks Technologies e: [EMAIL PROTECTED] w: +(65) 873 5989 w: http://www.scioworks.com m: +(65) 9782 9610 Scioworks Camino - Don't develop Struts Apps without it!

I also tried to used the ArrayList instead of a Vector what helps to get rid of the error message, however, the values are not copied. Are Lists not supported with the BeanUtils?

Question regarding sessions
Hi, I know that this isn´t a struts specific question but I really could do with your help. And this list is a guarantee for competent answers :-) ! My question is: how much should I save in a session? Scenario: I have a catalogue with say five levels: e.g. alcohol - wines - red wine - bordeaux - borgougne - grapes bla - grapes blub - Loire - white wine - rose All of these levels are displayed as a tree on the catalogue page. The question I have is as follows: should I save the comlpete tree (with description) in the session so that I only have to retrieve a particular level at any given time or should I just save the state of the tree (for example in a state object which also contains the shopping basket and user_id etc), which would just consist of the last node of the tree (node_id)? Lets say I have put something in the shopping basket and want to return back to the tree. Should I rebuild the whole tree by asking the service layer to return the tree depending on the last node_id or should I re-display the tree from the session? Any help on this matter would be very appreciated because it is always good to hear opinions from others.

Subject: Re: ActionForm and DynaActionForm
Hi,
So does this mean that if i am using DynaActionForm i dont need to
define any action form .i.e. a class which extends ActionForm and
has
all the get and set methods for input fields???
If you don't need custom reset() or validate() methods, that is
correct --
you do not need to create an ActionForm class of your own.
If you do need custom reset() or validate() methods, then you can
still
subclass DynaActionForm, but you only have to implement those two
methods.
so in this case how can
i access these fields on in my Action class, normally in my
ActionClass
i will get the values set in the fields from ActionForm class like
testform data = (testform) form; where testform is the class which
extends ActionForm and has get and set method, so in DynaActionForm
if i
dont have to define ActionForm, how can i get the values in Action
class
Ashish
DynaActionForm is an implementation of the DynaBean interface from
commons-beanutils -- see online JavaDocs at
http://jakarta.apache.org/commons/beanutils/api. So, if you've
declared
your form bean like this:
form-bean name=logonForm ...
form-property name=username type=java.lang.String/
form-property name=password type=java.lang.String/
/form-bean
then, in your LogonAction, you can access the properties like this:
DynaActionForm daf = (DynaActionForm) form; // Save casting every
time
String username = (String) daf.get(username);
String password = (String) daf.get(password));
There are also get() methods for accessing indexed and mapped
properties,
as well as set() methods to update all these things.
You can also use PropertyUtils and BeanUtils to access properties in a
DynaBean, because they call the get() and set() methods for you
transparently on a DynaBean.

Use ActionForm if you inherit your own JavaBean-compliant
FormBeans.
Use DynaActionForm if you don't want to code the tedious
getter/setter
methods but rely on the DynaActionForm's dynamic properties (think
name-value pairs, something like HashMap). (Note: DynaActionForm
is
*psuedo* JavaBean-compliant. It behaves as if it's a JavaBean with
the
BeanUtils library.)
To use DynaActionForm, you need to specify the elements
inside the config element and specify 'dynamic=true'.
Note that dynamic=true is no longer required in 1.1-b2. It was a
hack
to get around some developer laziness at the time this code was
initially
created :-).

RE: Question regarding sessions
A general strategy for sessions is to minimize the amount you have to store in them because the user is unpredictable and can cause your system to consume resources unneccessarily by loading up the session and then leaving (this can be controlled to some degree by using session time out and other techniques). By minimize, I mean storing a primary key instead of the entire object graph. Yes, this requires a database hit to retrieve the detailed information, but at least you have control over when the hit occurs. As far as using the ServletContext, you would only want to store static data here or provide the ability to refresh objects whose state is updated infrequently. Your question is quite common and you may want to search the mailing list archives for more solutions. The bottom line, is there is no simple answer. You have to weigh the pros and cons for your situation. You may want to check Sun's site and their Blueprints section for additional strategies. The J2EE interest list would be another good source for general server side programming questions. Oh yeah, theserverside.com is another good resource and Google and UseNet are also good resources.

I try to use DynaActionForms for the first time. I tried to do it
the
way explained below, but all I get from Tomcat is this errormessage:
Exception creating bean of class null: {1}
Does anybody know the meaning of this errormessage?
Are there some docs on the use of DynaActionForms somewhere out
there?
They seem to miss within actual struts docu...
Thx, Fabian

The question was, saving product objects with prices, descriptions etc in a vector and retrieving them again out of the session when the user wants to have a look at what he has added into the basket. Of course, again here, if there is a threat that details or availablity may change, then there is no point in saving whole product objects in the session. This is probably also very memory consuming?! I have previously stored just the product key (id), name, price and quantity in the shopping basket (session), ie, just the minimum. You will always need the key. The name is useful so that you can always show a sumary of what is in the basket. You need to store the price to avoid the situation of the prices changing during a session (dont want to give customers a nasty suprise). Quantity - always need this. If the user requests a detiled shopping basket display, wear the cost of doing a database lookup for the descriptions etc... Stock control. You have two choices, check for stock at product selection time, ie into the basket, or at checkout. If you decrement the stock count at product selection time, you can use a session listener to check if there are any items in the basket when the session expires. That way you can 're-stock' the shelves where you have abandoned shopping baskets. If you decrement the stock level at checkout time, you run the risk of running out - its as if somebody stole items out of your users shopping baskets as they were waiting at the checkout.. regards Rob MEMBERS EQUITY PTY LTD ABN 56 070 887 679 This email and any attachments are confidential.

RE: How to access current Tiles definition name?
Christian I don't think you can read the definition but you can get to the attributes. To change the menu look based on the page being displayed I use an additional parameter in each page definition - 'page'. The jsp then looks for the 'page' and modifies the menu to display the page being displayed. To modify the stylesheet and base template on the fly, I modify the base definition substituting the template and style attributes on the fly. There are a couple of examples of Tile reading and modifying the definitions in the Tiles war. There is a TilesAction that is initiated off the tiles definition with the controllerUrl parameter or a path parameter pointing to a TilesAction.

Editable/non-editable fields
Hi all, It's been some time, but it seems I'm back :) I'm currently working on a project where lots of forms are used. The forms are backed up by a DB. Somewhere in the DB, there is a table which tells me which fields should be editable and which shouldn't (they should only be displayed). Until now, we were looking in the db manually, and changing tags if some field changed from editable to non-editable. We want to change that: let our application look in the db and decide whether the current property should be editable or not. I've already implemented this for html:text fields (which was fairly trivial), but now I want to do this for html:select fields also. This seems to be less trivial to say the least. I just looked around on the net and found http://struts.application-servers.com, but it seems to be too restricting in terms of layout and granularity. Does anybody has any pointers on solutions for editable/non-editable fields? Basically I want one tag that can decide whether it's editable or not (based on business logic that I provide). Eg a text tag that is editable would generate the same output as html:text, if it's not editable it would be a bean:write followed by a html:hidden. (I've used struts some months ago, and I'm not totally up to speed with its recent developments, so please forgive me if this is a trivial question.) Any pointers are appreciated!

Populating values in checkbox incrementally and dynamically
Hi, The task is to populate values onto the checkbox dynamically and incrementally from an array. I have something like this in my jsp- logic:iterate id=user name=user html:multibox name=UserDetail property=status bean:write name=UserDetail property=status/ /html:multibox /logic:iterate getStatus() in my UserDetail bean returns an array of string. Here, I need the value for my checkbox to be in incremental fashion. Like, 1,2,3. I want my final HTML to look like: input type=checkbox name=status value=1 input type=checkbox name=status value=2 input type=checkbox name=status value=3 ...

Could you set the disabled attribute on the controls? This would still display the info to the user, but they wouldn't be able to edit it. On a previous project, we hacked some of the Struts tags to support this attribute, it wasn't that hard.

RE: Editable/non-editable fields
If I understand you question correctly, you want to dynamically determine whether to display the data in an editable manner or not. You could save the condition (that determines whether to allow edits or not) in the form bean and then do something like: logic:equal property=canEdit value=true %-- Editable version goes here --% /logic:equal logic:equal property=canEdit value=false %-- Non-editable version goes here --% /logic:equal At any given time either the editable or the non-editable version will be displayed.

If-Then-Else in Validator?
Hi All, I have a single form that, based on a bean property value, will display 1 of 4 possible input forms (this is used for data entry purposes). There is only one action associated with the form. In simple terms, it looks like this: html:form action=DataEntry.do method=post logic:equals property=TableName value=table1 ... display input form for table1 /logic:equals logic:equals property=TableName value=table2 ... display input form for table2 /logic:equals logic:equals property=TableName value=table3 ... display input form for table3 /logic:equals logic:equals property=TableName value=table4 ... display input form for table4 /logic:equals There are no common fields between the input forms. I would like to use Validator to handle all of my form validation, but cannot figure out how to do so. If I declare (in struts-config) that my form-bean is of type DynaValidatorForm, then I must validate all of the fields in the form-bean, whether they are required or not. If I use DynaValidatorActionForm, I don't know which fields to validate since the table can be different each time. I do have a html:hidden tag at the end of each table that contains the table name. Is there an If-Then-Else construct in validator that I can use to check the hidden text field and then perform the appropriate field validation? The only other option that I can see is to split the table into 4 separate forms, and then use DynaValidatorForm Any other ideas? Thanks in advance.

submit form from popup window to parent window

Re: RE: Editable/non-editable fields
Hi Sri, Thanks for your reply. There are a few problems though: 1) I don't like to have a myriad of logic:equal in the jsp's. They tend to become unmaintainable. 2) More important, there won't be one global canEdit property: each field would have to decide for itself whether it's editable or not. Something like blah:text name=myName property=myProperty/ would look in the DB to decide whether myName.myProperty is editable or not. It's all about granularity (the same problem I'm having with the layout: taglib).

i18n of internal messages
Hi, I need to customise some internal messages (org.apache.struts.taglib.LocalStrings.properties, org.apache.struts.util.LocalStrings.properties...).

Re: Newbie logic:iterate question
I figured out my problem...I had a small logic error elsewhere in my code,
so
the form was returning a null for the String array. Struts does NOT like
null
arrays, and it was apparently going into the ozone. It would be nice if
Struts
detected nulls and threw some sort of an error.

Oops. I found where the problem is:
ActionErrors errors = new ActionErrors();
errors.add(ActionErrors.GLOBAL_ERROR,
new ActionError(error.tablemessage, (String)Pass My message));
saveErrors(request, errors);
Pass the message as a String Object or Integer Object is what is
expected :)

Vivek,
I have used syntax nearly identical to yours successfully in Struts
1.02. Could be a problem with your jsp or control flow. Do you
see
the errors header and footer displayed or are you getting a blank
page?
I would suggest the following:
0. Inspect your container logs
1. Verify that you have the struts bean and html tag libs
referenced in
your jsp and there are no other problems in the jsp
2. Add some logging to verify that the ActionErrors constructor is
getting the actual parameters that you think it is getting
3. Add logging to verify that the saveErrors is getting executed
hth,
Phil

Iterate tag within an iterate tag
Went through the achives to find out if having an iterate tag within an iterate tag is possible. Didn't find anything. So basically, my question is 1) is it possible. and 2) if so, how. This is what I've done, but it's not working.. logic:iterate name=results id=collElem I am then able to access all this collections getters if they are returning String via the bean:write tag like this bean:write name=collElem property=key/ if the getter returns a collection, how do I iterate through that result the getter in the bean is (in this case) getAttDetails() for the collection that I now need to iterate through. If I do this bean:write name=collElem property=attDetails/ in the first iterate tag it prints out the following to my jsp [com.ag.armata.contentserver.OptionBean@475d, com.ag.armata.contentserver.OptionBean@6275], which looks to me like it's just simply calling the toString() method on the object. What I, in essence want to do is this logic:iterate name=results id=collElem bean:write name=collElem property=key/ logic:iterate name=bean:write name=collElem property=attDetails/ id=attDets bean:write name=attDets property=key/ = bean:write name=attDets property=value/ /logic:iterate /logic:iterate This obviously does not work...

Re: Status of Struts integration with container managed securityand alternatives
I did answer your question ... maybe you missed it. The roles attribute on an Action element will *not* (by itself) trigger a container-managed login. You must also protect *all* URLs with an appropriate security constraint (mapped to *.do, for example) that forces login but allows everyone in.

Request Beans Sanity Check
Hi, Having problems creating beans on the fly. Can somebody spot where I have gone wrong... This is my (obviously incorrect) understanding of the procedure: 1. I create a bean called MyBean 2. an action script creates an instance of the MyBean class, called (say) MB and initialises it... so far so good 3. add the bean to the request scope in the action request.setAttribute( MyBean, MB ); the action forwards to a .jsp page (correctly) 4. the page tries to access a collection defined in the bean: logic:iterate id=item name=MyBean property=MyCollection ..etc.. result: Cannot find bean MyBean in any scope what might I be doing wrong?

Hesitation leads to NullPointerException
Using Struts 1.0.2 on Tomcat 4.0.2
bizarre.alert
I have a problem that only occurs if the user lingers on a page for a while (say a few
minutes). If after this duration, the user triggers any action, the application
crashes with a NullPointerException.
I have debugged the exception as being caused by a null property of the form bean.
The question is this: how did the list get to be null. Why does it become null only
if the user lingers?
The form bean (ProductsListBean) contains :
private ArrayList products;
public List getProducts() { return products; }
This list is used to display a collection of products for the user to select (so, I
know that the list is non-null non-empty). In the processing of the user action,
the following logic can be found
...
List products = productsListBean.getProducts();
Iterator iterator = products.iterator();
...
Obviously, (since the list is null) the application throws the exception at the second
line above.
/bizarre.alert
Since the stack trace on the browser didn't indicate the Root Cause I went looking
for the Tomcat log -- it said the same thing that was on the browser. No more
information.
BTW my session timeout is set to 30 minutes and the this problem presents itself if
the user pauses for 2-3 minutes.

Re: j_security_check, jaas and weblogic 6.1
JAAS is not relevant if you're using container-managed security. You'll need to set up users in whatever user database your container (WebLogic in your case) provides. Struts also has nothing to do with this -- although you can use role information with tags like logic:present or the roles attribute on an action if you want to. JAAS would only be relevant if you wanted to do application-managed security instead, or if you were implementing the container itself.

Re: Iterate tag within an iterate tag
I've done this... The way I did it is the outer tag needs to populate data into a TagExtraInfo class. The inner tag can now use this data. You also have to make sure in your tld you tell it the TagExtraInfo class you are going to use. I've passed the data in the TagExtraInfo class into the attributes of the inner tag. This is great for iterating through lists. You can use the outer tag to pull the data and the inner tag to take it and put it in a table or something. That way you can separate the data collection from the the handler/view/manipulator for that data. I learned how to do this from the book Java Server Programming J2EE edition. Excellent book.

Darryl Nortje [EMAIL PROTECTED] on 08/26/2002 10:49:39 AM Please respond to Struts Users Mailing List [EMAIL PROTECTED] To: 'Struts Users Mailing List' [EMAIL PROTECTED] cc:(bcc: Joseph Sadove/DKBDS USA/DKB) Subject: Iterate tag within an iterate tag Went through the achives to find out if having an iterate tag within an iterate tag is possible. Didn't find anything. So basically, my question is 1) is it possible. and 2) if so, how. This is what I've done, but it's not working.. logic:iterate name=results id=collElem I am then able to access all this collections getters if they are returning String via the bean:write tag like this bean:write name=collElem property=key/ if the getter returns a collection, how do I iterate through that result the getter in the bean is (in this case) getAttDetails() for the collection that I now need to iterate through. If I do this bean:write name=collElem property=attDetails/ in the first iterate tag it prints out the following to my jsp [com.ag.armata.contentserver.OptionBean@475d, com.ag.armata.contentserver.OptionBean@6275], which looks to me like it's just simply calling the toString() method on the object. What I, in essence want to do is this logic:iterate name=results id=collElem bean:write name=collElem property=key/ logic:iterate name=bean:write name=collElem property=attDetails/ id=attDets bean:write name=attDets property=key/ = bean:write name=attDets property=value/ /logic:iterate /logic:iterate This obviously does not work... Does anyone know how to do what I've tried to explain as best as possible here.

Adding errors to request in a DefaultAction
I have an ActionFilter that maps to /do/*. In this class, I detect if
the user has a missing password_hint and if so, set a session
variable, missingHint. Then in my DefaultAction (which forward to the
Main Menu), I have code to check for that variable and forward - but
it's not working - any ideas? The logging message building missing
password hint warning IS getting logged.
// Extract attributes we will need
ActionErrors errors = new ActionErrors();
...
String requestURI = request.getRequestURI();
String contextPath = request.getContextPath();
String forwardPath = requestURI.substring(contextPath.length());
forwardPath = forwardPath.substring(
forwardPath.indexOf(do/) + 3, forwardPath.length());
if (forwardPath.indexOf(mainMenu) != -1) { // routing to Main
Menu
if (session.getAttribute(missingHint) != null) {
if (logger.isDebugEnabled()) {
logger.debug(building missing password hint
warning);
}
// add warning message to the request
errors.add(ActionErrors.GLOBAL_ERROR,
new ActionError(errors.missing.hint));
saveErrors(request, errors);
session.removeAttribute(missingHint);

RE: using O/R mapping tools
Erasmus's In Praise of Folly was a tribute to his friend Sir Thomas Moore, the murdered Archbishop of Cantebury, who stood on principle, considered to be the most erudite man in the Christian World at that time. Folly is a pun for Moore. This does not stop the misreading of that book. The second line of When in Rome, do as the Romans do, from Seneca, is When not in Rome, do as the Romans do. In the last chapter (ten) of Plato's Republic, the main man (Socrates) decides to choose the life of an ordinary man who minds his own business. This is from a book that is traditionally (by those who stop at chapter five) read as an apology for some sort of Uber man, when it is in fact a reductio ad absurdum of that very idea. Meaning and myth and truth have strange companions, indeed.

Mark, there is a difference between saying that the world is flat, which is a myth by the way, and saying that round MEANS flat, because Charlie Brown is a two dimensional character.

Using Struts 1.0.2 on Tomcat 4.0.2
bizarre.alert
I have a problem that only occurs if the user lingers on a page for a while
(say a few minutes). If after this duration, the user triggers any action,
the application crashes with a NullPointerException.
I have debugged the exception as being caused by a null property of the form
bean. The question is this: how did the list get to be null. Why does it
become null only if the user lingers?
The form bean (ProductsListBean) contains :
private ArrayList products;
public List getProducts() { return products; }
This list is used to display a collection of products for the user to select
(so, I know that the list is non-null non-empty). In the processing of
the user action, the following logic can be found
...
List products = productsListBean.getProducts();
Iterator iterator = products.iterator();
...
Obviously, (since the list is null) the application throws the exception at
the second line above.
/bizarre.alert
Since the stack trace on the browser didn't indicate the Root Cause I went
looking for the Tomcat log -- it said the same thing that was on the
browser. No more information.
BTW my session timeout is set to 30 minutes and the this problem presents
itself if the user pauses for 2-3 minutes.

Sorry i should have provided more details in my original question
with the same following code :
html:select property=room.CDRRoomUseID
value=%=Room_Obj.getCDRRoomUseID_desc() %
html:options collection=CDRRoomUseList property=CDRRoomUseID
labelProperty=CDRRoomUse / /html:select
var types :
room.CDRRoomUseID - int
value = String
the options block is essentially recording CDRRoomUseIDs (of type int)
to be saved to room.CDRRoomUseID, the display however, would be strings
(labelProperty = CDRRoomUse) therefore your suggestion would not take
hold.
Do you have any more suggestions? help much appreciated.
Kael

You don't need the value attribute. All you have to do is set the
property attribute of the html:select (room.CDRRoomUseID) to the value
you want displayed by default. For example, if room.CDRRoomUseID is set
to 'foo' and 'foo' is one of the value in the collection CDRRoomUseList,
it will show selected when the page loads.

Subject: html:select question
I'm trying to create a drop down Combo Box that allows
a user to select a choice out of many from a given list.
This would sort of be like an update process for an
existing database entry.
I would like to display the original data as the default
entry for the combo box.
According to the API, this can be done by setting the 'value'
attribute for html:select, i have tried doing so but was not
successful. The default value that is displayed on the combo box happens
to
be the first value returned from the List, i.e. CDRRoomUseList
I have written the following code segment :
// bean declarations
jsp:useBean id=CDRRoomUseListclass=java.util.List
scope=request /
// for generating the drop down combo box
html:select property=room.CDRRoomUseID value=%=
Room_Obj.getCDRRoomUseID_desc() %
html:options collection=CDRRoomUseList property=CDRRoomUseID
labelProperty=CDRRoomUse / /html:select
I have even tried doing :
html:select property=room.CDR... value=test
but this did not work as well.
Can anybody point me towards the right direction?
Thanks for any help in advance.

Re: j_security_check, jaas and weblogic 6.1
Thank you! You are the ONLY place I've heard this! Now everything seems to make more sense. I was just going to use j_security_check hooked into Weblogic RDBMS and put the user in the session for authentication from there on in (JNDI security to EJB). So this looks like the right path? No offense, but is this right? BEA recommends you use JAAS all over the place. I'm mainly going to use ACL in the deployment descriptors for my web app and ejbs. I also noticed that almost all JAAS implementations were at the java client layer. Few were servlets, etc. This would make sense with what your saying because no container would exist at a pure java client layer (such as with the JAAS RMI example that comes with weblogic). BTW, EXCELLENT job with struts Craig and team. I have 2 systems IN PRODUCTION! using struts. They wrote one at the job I'm at and I recommended struts to replace it. We are now going full steam ahead with struts! thanks, Mike Lee - Original Message - From: Craig R.

You'll need to set up users in whatever user database your container (WebLogic in your case) provides. Struts also has nothing to do with this -- although you can use role information with tags like logic:present or the roles attribute on an action if you want to. JAAS would only be relevant if you wanted to do application-managed security instead, or if you were implementing the container itself.

I read all through the examples on j_security_check, jaas and WLS RDBMS out there I could get my hands on. There seems to be no good real world examples of how to tie all these together. The reason I'm having an issue is struts is the middle man, the controller so he is key to it all. I know i configure j_security_check in my web.xml to point to use form authentication, i know all about deployment descriptor configuration for ejb, war, etc. This is not the problem. I don't see how JAAS fits into j_security_check? I also dont see how struts fits into it either? Do I need to also add a login.do? I need to get the locale for the user from the database and figured I would do this at the login. JAAS wants LoginContext.login(), most j2ee say j_security_check and struts examples have login.do (this is the way I've typically done it). Help!

I decided (in response to your email) to display the maxInactiveInterval. I nearly
fell off my chair when I saw the console read '60 seconds'!!
This was a case of the source control not managing what's on the Tomcat server.
Source control's web.xml read

But Tomcat's version read

Using Struts 1.0.2 on Tomcat 4.0.2
bizarre.alert
I have a problem that only occurs if the user lingers on a page for a while (say a few
minutes). If after this duration, the user triggers any action, the application
crashes with a NullPointerException.
I have debugged the exception as being caused by a null property of the form
bean. The question is this: how did the list get to be null. Why does it
become null only if the user lingers?
The form bean (ProductsListBean) contains :
private ArrayList products;
public List getProducts() { return products; }
This list is used to display a collection of products for the user to select (so, I
know that the list is non-null non-empty). In the processing of the user action,
the following logic can be found
...
List products = productsListBean.getProducts();
Iterator iterator = products.iterator();
...
Obviously, (since the list is null) the application throws the exception at the second
line above.
/bizarre.alert
Since the stack trace on the browser didn't indicate the Root Cause I went looking
for the Tomcat log -- it said the same thing that was on the browser. No more
information.
BTW my session timeout is set to 30 minutes and the this problem presents itself if
the user pauses for 2-3 minutes.

You are the ONLY place I've heard this! Now everything seems to make more sense. I was just going to use j_security_check hooked into Weblogic RDBMS and put the user in the session for authentication from there on in (JNDI security to EJB). So this looks like the right path? If BEA did things correctly, you shouldn't have to do anything special about saving the user in the session for EJB authentication -- the same user identity should be carried over automatically. No offense, but is this right? BEA recommends you use JAAS all over the place. I'm mainly going to use ACL in the deployment descriptors for my web app and ejbs. I also noticed that almost all JAAS implementations were at the java client layer. Few were servlets, etc. This would make sense with what your saying because no container would exist at a pure java client layer (such as with the JAAS RMI example that comes with weblogic). JAAS is what I'd use if I was writing the back end of WebLogic's servlet container. But web applications that run inside the container should not have to know anything about it. As you note, client apps don't have that kind of container support, so a roll your own solution based on JAAS makes more sense there. BTW, EXCELLENT job with struts Craig and team. I have 2 systems IN PRODUCTION! using struts. They wrote one at the job I'm at and I recommended struts to replace it. We are now going full steam ahead with struts! thanks, Mike Lee Craig -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
