html:messages Design issue: mixing data and presentation!!!!
Hi, A great thing with Struts is the error validation capabilities. However, the use of html:errors/, or lately html:messages, poses a problem that I found not to be a very good design (though it is slightly better in the messages tag). What I don't like is, in order to get any presentation formatting on the header and footer, you need to enter html in the resources and therefore mixing up data and presentation. An example where this apply is that we have an i18n utility where the administrator for each country can translate all messages from a default language into their local language and for the messages headers and footers they have to see the html as well. Has anyone thought of this before? /Johannes _ Hitta snörapporter... från 500 olika skidorter i Europa på http://se.snow.yahoo.com -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

I'm new at struts, but I have tried it and It's just what our company

I get an Exception: blab la Could instantiate bean

Data entry is a cumbersome process. Users must be incented through the process by parsing the process itself into manageable chunks and giving users motivation throughout. Consider a wizard-based data entry metaphor to correct this issue. Also, make sure that you give appropriate feedback to the user after each wizard step. Consider also adding a motivator and possibly even a step-map that shows location in the overall data entry process.

Re: Long term Session attributes [ was RE: Wizard Interface question ]
I made a mistake with the method names, perhaps this is much clearer
public interface SessionLeaseable {
public void updateLastAccessTime();
public long getLastAccessTime() ;
}
Clearly every `SessionLeasable' will call its `updateLastAccessTime()'
method to refresh the internal time value.
Here is an example of a bean that avoids the threading issue
public AcmeBean implements SessionLeaseable {
String coffee;
volatile long actime;
public String getCoffee() {
updateLastAccessTime();// !
return actime;
}
public void setCoffee( s ) {
updateLastAccessTime(); // !
this.coffee = x;
}
public synchronised void updateLastAccessTime()
{ actime = System.currentMillisecs(); }
public synchronised long getLastAccessTime()
{ return actime; }
}
Moreover, if you follow the AXIOM, that
every navigation invokes an ACTION that generates a VIEW
and I never navigate to VIEW directly
then you can write logic to reactivate beans that have been timed-out,
or take appropriate countermeasure in your Struts Action.

Re: Design question about ActionForm's validate method
Unfortunately, we don't have free reign on conventions, and are restricted to the patterns that the container will match. The container gets the request first, and then passes it along to Struts. For the best compatibility, a single, very simple pattern is best. One way to think about it is that the Actions are your applications API, its command set. They represent everything that your application knows how to do. One thing it does is display a form for adding a new record. Another thing might to display a page summarizing the entered data, or a page for editing the data. Displaying a form is sometimes a simple process. Often times, it is not, since dropdown boxes must be populated, security parmeters might need to be checked, other customizations might need to be performed. In practice, there is sometimes a lot to do even to simply display a data entry form. I tend to break my applications into modules, which sometimes correspond to the major tables in a database, or at least the major databases views. So I would tend to represent the URIs you mentioned as /adddress/Form.do /address/Store.do /address/View.do or /do/adddress/Form /do/address/Store /do/address/View -Ted. Alex Paransky wrote: Ok, I understand how forcing all requests through the controller is a good thing. Now, I have various types of pages: Forms - html:form... Actions - .do action of the form View - basic .jsp page to view and link to a form for further edit Is there a naming convention that you found works for you? Since, I am using .do extension for everything, it seems like I have URL's which look like this: AddressForm.do AddressSaveAction.do AddressView.do I think it would be nice to have: Address.form AddressSave.action Address.view Or something like this. The .do extension makes me think of action and I don't see a form or a view as an action. I could always map *.view and *.form to execute the servlet as well, but then Address.form and Address.view are ambiguous. Any suggestion on naming conventions?

This centralizes control over the hyperlinks in the Struts Config, which yields a number of benefits. In Struts 1.1, now the Nightly Build, support has been added for multiple Struts configuration files. In order for this feature to work, any request for a presentation page that uses elements from the configuration file (ActionForms, forwards, mappings) must be routed through the controller. This allows the controller to make the appropriate configuration available for a given page. This is becoming a common pattern, since the Velocity support, and I believe the X2 servlet, also need you to do the same thing for the same reason. The controller needs to touch the request to prepare it for the presentation layer. Many other features in advanced applications, including security, logging, and screen definitins, are easier to implement when everything passes through the controller. In a strict MVC implementation, the controller is responsible for interacting with the user. It then follows that all requests from the user should flow through the controller. Some of us had been counting the ActionForwards as flowing through the controller, but as the framework expands, and more services are being plugged in, passing the actual request through the controller becomes more and more desirable, until it's really not worth making the occasional exception any more. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Java Web Development with Struts. -- Tel +1 585 737-3463. -- Web http://www.husted.com/struts/ Alex Paransky wrote: So do you mean, all pages go through the Action?

I'm new at struts, but I have tried it and It's just what our

our
app. is dynamic. Thus, I have found at the mailing list a
DynamicProperty zip file so... I have compiled it to the struts jar and
did
the example but I have this small problem.
At this section:

I get an Exception: blab la Could instantiate bean
'mainForm', neither 'class' nor 'beanName' were specified bla.. bla..
So as I see it, the bean thru struts is not in session scope,
so
I don't have this bean so I'm ...beeep!

great, but if not I think I'll have to write something else and I don't

By the way, is there any chance to know when is the next

Sorry, I think that I didn't make my self clear,

the values are my form fields so, how can I make a setter and getter

RE: Dynamic Property.
Arik,
The Action class perform method passes in the HttpServletRequest which
provides
access to all the parameters entered via the HTTP request (ie. a form POST)
I believe one common technique would be to dynamically generate your form
fields by giving
them names like name.1, value.1, name.2, value.2, name.numeric_identifier,
value.numeric_identifier etc...
When the form is submitted to your Action class for processing, you can
iterate through the request parameter values and access common values based
on
their numeric_identifier extension.
This is a manual way of doing it. I've seen some threads on this list that
talk about
dynamic forms but I'm not sure where they are.
One good resource to check is the mailing list archive.
http://www.mail-archive.com/struts-user%40jakarta.apache.org/
Like I said, there may be a more eloquent solution, but I know the
above works.

Turbine style multiple method actions
I'm just trying to catch up with what's changed in struts 1.0.1 / 1.1
from the version I previously used (pre version numbers). Is there a
facility to map a request to different methods / actions based on a
request parameter?
For example, if the request contains a parameter function, can I
choose the Action that will be invoked, or alternatively, can I invoke
different methods in the action defined in the form.action URL, based
on some parameter? I realise I can change the URL using javascript on
the html form, but this removes the struts config as the control of app
flow. In my previous apps, we found theat often you end up writing
Action classes similar to:
myAction(..) extends Action {
if (null == function) { doView(..) }
else if (submit.equals(function)) { doSubmit(..) }
else ...
prepareRequest(req, ..);
return mainPageForward;
}
etc
Which makes the action into a type of mini controller. I know this
could be done in a more OO way, but that's not my point, I'd like the
controller to be able to do this in some way. Turbine does this in a
very similar way (though I'm not sure I like their parameter
convention).
My only issue with doing this in the main ActionServlet is that
partioning of the logic should perhaps be encapsulated better -- though
the XML config file provides a suitable scoping for this information.
I've not been keeping up with the nightly developments - does the
multiple applications, stuff allow this kind of thing?

Migrating from another framework to struts ...
Hi, We are currently migrating from another framework to struts. This has brought about a lot of queries doubts about how we can use struts to do things for us that the earlier framework provided. My main concerns are : 1. Does struts provide any build-in mechanism for session management? If not, then is there any guideline as to how struts can be used to provide that kindof support? 2. How do I deal with form beans that have aggregate objects in them. For example, I have a class called UserInfo, which has the username the user address (which is another class called AddressInfo) among other things. Now, if I have to use UserInfo class to display/edit user information in a form. How would I manage that? 3. I'm also having problems with URL forwards. It looks like in struts you have give URL forwards starting with /. What if I want to forward to a URL that doesn't being with /, i.e., a relative URL. Say my site looks something like this http://mysite.com/info1/info2/actionname and I would want to carry this URL for all the actions, ie, only the action name would change the rest of the URL remains the same. Maybe I'm missing soemthing out here. These are few of the questions that I had. Since I'm new to struts, these questions may be naive.

1. For one, what do you mean autmatic session management, you can put form beans into the session and work with them. So if you mean that with session support it supports it 2. You need getter and setter in your UserInfo form for the aggregated forms. Than struts can call them with the following entry html:text property=address.street/ Struts will call first the getter getAddress() and then getStreet() 3.

In furtherance of Oliver's response: cool dude wrote: 1. Does struts provide any build-in mechanism for session management? If not, then is there any guideline as to how struts can be used to provide that kindof support? For the most part, Struts relies on the Java Servlet container for that.

Maybe I'm missing soemthing out here. Struts looks as these as String identifiers rather than a file tree, and does not resolve relative references in the way that you might expect. It's important to remember that while we assign URI to actoins that look like references to directories or files, these don't exist in fact. You are not really forwarding to a URL that resolves to a file, but to an identifier that Struts looks up in a table.

Instead they incorporate it by reference, much like calling a block of methods. So, with tiles an engineer might create a new Result page by adding this to a configuration file definition name=.item.Result extends=.Result put name=title value=New Item Result / put name=contentvalue=/pages/item/NewResult.jsp / /definition and then just writing the NewResult.jsp segment that exposes the result set (simplified from production, but this would work) logic:notEqual name=RESULT property=size value=0 TRTDTABLE width=100% TR class=greybg THitem/TH THname/TH THcategory/TH THdonor/TH THscript/TH THtype/TH /TR TR TDbean:write name=row property=item//TD TDbean:write name=row property=name//TD TDbean:write name=row property=category//TD TD align=rightbean:write name=row property=donor//TD TDbean:write name=row property=script//TD TDbean:write name=row property=itemType//TD /TR /logic:iterate /TABLE/TDTR /logic:notEqual The rest of the page, headers, footers, menus, even control buttons, can all be inherited from a layout that the HTML dude has crafted.

RE: Dynamic Property.
you can use either indexed or mapped properties in struts for this.
Alternatively the standard request.getParameterNames/getParameterValues
will supply all the data values.
For the mapped properties, use something like:
input type=text name=prop[%= rowNum %]
or
input type=text name=prop{%= name %
which will call a setProp(rowNum, value) or setProp(name, value)
Note: to use the mapped properties (indexed by name) you need to use
either BeanUtils from Commons or get a nightly of struts.

However, the use of html:errors/, or lately html:messages, poses a problem that I found not to be a very good design (though it is slightly better in the messages tag). What I don't like is, in order to get any presentation formatting on the header and footer, you need to enter html in the resources and therefore mixing up data and presentation. An example where this apply is that we have an i18n utility where the administrator for each country can translate all messages from a default language into their local language and for the messages headers and footers they have to see the html as well.

ActionForward usage.
Regarding a post Ted made a couple of days ago. (Which a copy of follows this post) As well as some other general questions. I would like to pre-populate my form field values from a database datasource. I am using the following configuration which to be honest is giving me a bit of a headache and I hope someone could improve it for me. action path=/addItem type=actions.AddItemAction name=AddItemForm scope=request input=/pages/addItem.jsp validate=true forward name=selfpath=/pages/addItem.jsp/ /action Initially if I want to add an item I forward to /addItem the AddItemAction detects whether or not this is the first visit to the form and if so places data from an rdbms into the HttpServletRequest object and calls the ActionForm (AddItemForm)'s reset() method to populate the form. The AddItemAction then forwards the request to the self forward which displays the form for the user to enter his or her own new data. The user then submits the form back to the /do/addItem and this time the action detects that the form had been prepopulated and that the data should be validated and inserted into the rdbms upon completion the AddItemAction then forwards the request to some global forward. Now at a first glance this obviously sucks. A couple of days ago however I saw a post that Ted had made about mapping all request through actions that I thought might help me to solve the above problem. (the post attached below) From the configuration in Ted's post I developed this new configuration (which doesn't work). I set it up initially with the intent that I would subclass the ForwardAction class and have it pull the data from the rdbms stick the data in the request and then call the forms reset() method to populate the form. However before getting around to that I figured I'd just try setting it up to forward to see if I ended up at my addItem.jsp form. action path=/addItemGet type=org.apache.struts.actions.ForwardAction parameter=/pages/addItem.jsp name=AddItemForm scope=request validate=false /action action path=/addItemSet type=actions.AddItemAction name=AddItemForm scope=request validate=true input=/pages/addItem.jsp /action Unfortunately this is the error I get: elysium# 2002-02-08 09:56:37 - Ctx(/ims) : Status code:500 request:R( /ims + /do + /addItemGet) msg:No action instance for path /addItemGet could be created I've posted about form pre-population before and a couple of you were able to help me out but clearly I misunderstood. So please if you reply be as verbose and explanitory as possible thanks. The best practice now is to use ActionMappings for everything, so that the reqeust passes through the controller. This buys you several important capabilities that become important as applications grow. Not the least of which is the new support for multiple applications in the Nightly Build. The ActionMapping has a validate property that you can use to turn off validation when the mapping is used to initialize a new form. So, typically, you will have an ActionMapping for each circumstance. action path=/item/Add type=org.apache.struts.actions.ForwardAction parameter=/pages/item/Form.jsp name=itemForm scope=request validate=false /action action path=/item/Store type=org.apache.gavel.item.http.Store name=itemForm scope=request validate=true input=/pages/item/Form.jsp forward name=continue path=/do/donor/Detail/ /action -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: Problem with UTF encoding with Action Form
Tony, Try sending your request to your server via a telnet connection. That way you will be able to see in the headers if the correct content type has been set and what the character values are that are returned. I'd suggest creating a file with the HTTP POST in and having telnet read it. Bit of a pain but then at least you'd know what was happening. Actually, rather than messing with multi-part posts, you could probably use a HTTP GET with the name/value pairs tagged onto the URL. What servlet container are you using? There is a possibility of a bug with the page directive...

Re: Problem with UTF encoding with Action Form
Try reading a really good resource on character set encoding. http://tagunov.newmail.ru/i18n/i18n.html It sounds to me like the request params aren't being decoded properly when they are being processed by the web container. I'd suggest looking at the section on Decoding request parameters under Servlet 2.3 containers. The 2.3 method on the request, request.setCharacterEncoding( String env ). It might be just what you're looking for. As long as you call this method before any of there request params are read (which means you'll have to mod the controller servlet), you can specify whatever encoding you want when reading the chars from the request. You could get fancier with supporting multiple character sets in your app by checking the user's locale and making some assumptions about what character sets are used (GB for Chinese, Big5 for others, etc.) --Michael Antony Stace wrote: Thanks Chris for the reply.

Re: Tiles Vs Templates
This prove that there is a need in such kind of frameworks ;-) At first glance, it looks like similar to Tiles. I will investigate more on it asap. Also, Tiles is open, and anyone can participate to improve it, bring new ideas, and why not starting its successor ;-) Cedric nicolas bonvin wrote: Hi everyone, I do not want to start a flame war out here but after trying Templates and Tiles, I recently successfuly used a custom Web Toolkit (wtk) on a couple of J2ee projects. It is available at http://ultrawork.sourceforge.net. The org.ultrawork.wtk.mc package provides a few classes and taglibs that let you use strongly typed components inside Jsps or Servlets. The following components are available : Page, represents an Html markup document. Container, can hold components and arrange how it display them using a layout. Text, represents internationalizable text. Block, represents a fragment of markup. Link, represents an html link to either a resource that is located inside the web application, or to an external resource. My 2ç on the 3 alternatives : Templates, pros: very simple Templates, cons: lacks important features such as central-definition of components no inheritance between components Tiles, pros: very powerful compatible with Templates provides central-definition of components inheritance Tiles, cons: has a bigger API (more than 40 classes) lacks real component types such as texts, links, or markup fragments I found it more complicated to extend, especially when writing portal-type user-customizable pages. you have to specify a name to any component you create, even if the component only exists within another one. org.ultrawork.wtk.mc, pros: simple (18 classes) and easy to extend offers different types of components including containers and i18n support Jsp and Servlet layouts implementation simple syntax with the lowest possible overhead when defining complex components access to the components graph of a container through a dotted syntax org.ultrawork.wtk.mc, cons: yet another new component toolkit (mc stands for More Components) hope this helps, nicolas -Original Message- From: Sriram Nookala [mailto:[EMAIL PROTECTED]] Sent: Monday, February 04, 2002 6:50 PM To: Struts Users Mailing List Subject: Tiles Vs Templates I'm trying to get some information in order to make a choice between struts templates and Tiles for our UI design and templating.

Sorry for the wrong response before, it is what happen when you do to much things in the same time. It is normal that the componentContext is not found if you access directly the action (with *.do).

A workaround is to have another action forwarding to the action overloading parameter.

If the actionForward contains a definition name, the definition is retrieved, and missing attributes are added to your definition.

SSL + URL rewriting problem
Hello all, I've been trying to get my Apache 1.3.22 + Tomcat 4.0.1 [via mod_WebApp] installation to work with SSL. So far I've had some success, but there is one problem left that seems to only effect Struts applications. All my non-struts .JSP's and servlets work without any issues. But in Struts, all of the URL's are being written like this: http://www.hostname.com:443/strutsapp/... I'm probably missing something that will be fairly obvious to some of you but I just can't seem to figure it out. Do any of you have suggestions, or links to help me out?

Re: Migrating from another framework to struts ...
Hi Ted and Oliver, First lemme thank you guyz for the quick response. Few of your suggestions have really helped me. But my problem with relative URL still remains. Maybe I didn't explain the problem in the right manner. Lemme tell you what the exact scenario is. I have a URL which looks like http://www.mysite.com/US/en/brandname/actionname. This would be the URL even for the starting page, with actionname being say home. I need such a lengthy URL because the site supports multiple countries languages brands. I get this information form the URL. I know we could have send this information even as a querystring but unfortunately this is the standard URL now and I can't change it. Now the problem is this: If I give the action name as just login in the html:form I mention login it does not find the action mapping. It gives me a error when I submit to this form saying that there is no mapping for action name /login. Why does it convert login to /login I have no idea about ... its being done internally in the struts FormTag. To solve this problem I changed the action name to /login in my struts-config.xml it worked but then the URL changed to http://www.mysite.com/main/login You would notice that I lost the country, language brand information. I need all these information in the all the pages to cater for bookmarking, ie, when a user bookmarks a page I should be able to recreate the page with his preferences, which I can do only if I have this information in the URL. How can I solve this problem? As I'm a newbee I might be ignoring something really obvious ... hope you guyz can help me out with this on e... Thanx in advance, Vikram. --- Ted Husted [EMAIL PROTECTED] wrote: In furtherance of Oliver's response: cool dude wrote: 1. Does struts provide any build-in mechanism for session management?

I'm also having problems with URL forwards. It looks like in struts you have give URL forwards starting with /. What if I want to forward to a URL that doesn't being with /, i.e., a relative URL.

Maybe I'm missing soemthing out here. Struts looks as these as String identifiers rather than a file tree, and does not resolve relative references in the way that you might expect. It's important to remember that while we assign URI to actoins that look like references to directories or files, these don't exist in fact. You are not really forwarding to a URL that resolves to a file, but to an identifier that Struts looks up in a table. While seems like it would be feasible for Struts to treat this table like it were file tree, that functionality is not provided. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Java Web Development with Struts. -- Tel +1 585 737-3463. -- Web http://www.husted.com/struts/ -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] __ Do You Yahoo!?

Re: ActionForm:reset() method
I think it's this simple:- (but experts please correct me if I'm wrong) When your action is invoked if it specifies a form bean struts will call reset on it before calling your perform method. This is true when the action is invoked from HTTP either when your form is submitted (from submit button) or when it's started thru a link (or redirected to). Struts tries to move the form fields (from a submit) or request parameters (from a link) to the corresponding form bean properties after the call to reset. It's also true when you do a struts forwardTo(mapping, someAction). If someAction is associated with someForm, someForm.reset() is called before calling someAction.perform(..). Note the previous action may have left it's form bean in the request (it normally should delete it), but struts won't call it's reset, only that of the new form. Hope this makes sense, keith. --- rob [EMAIL PROTECTED] wrote: Under what circumstances is the reset() method of an ActionForm called on the struts programmers behalf without them (the struts programmer) explicitly calling reset() in their own code?

Re: Problem with validation

Re: feed-forward data
I need an answer to this in a hurry It's a big question - a hurried answer might be wrong. not had luck searching the archives. but there's lots of stuff there! Has anyone got this logic in a live system can comment from practical experience? --- Hidden fields are passed into the form bean by struts (if they have a corresponding setter method) same as visible fields. So in your set of web pages each has every field on it. For each page the irrelevant fields are hidden. That would be OK. I suspect you might get problems if the user breaks up the flow of your app - the data in the request could get lost. Many people use a form Bean in the session which has every field in it. This keeps your jsp's cleaner (no hidden fields). You may have unwanted data left in the session if user doesn't complete the work flow. Also problems with session timeout when user didn't want to lose the data. Me I love databases like to store things there, with status codes to indicate if data is valid /or complete. For a little app I think your hidden fields theory is OK. If you are writing a Bank Account opening app, I'd use a database, you can't lose the data by mistake, which would annoy your potential customer. You could write a big article on this stuff argue all day!

Re: Design question about ActionForm's validate method
RE: Design question about ActionForm's validate method The process we followed is very simular to what Ted suggested but depends on how you are approaching the construction of your actions. If you have the ability to write a collection of objects that handle storing and retreiving data irreguardless of the data you might map it like this: /do/store/address /do/load/address /do/load/user etc ... If however you want to segment it out as to what you are working on and then the action you are performing on that thing you would merely reverse it to this: /do/address/load /do/address/save /do/address/delete No what have we done in practice is a combination of those two. For one project we were able to encapsulate the loading, sending, and saving type of actions into one an action for each and thus the namespace we defined for this was simular to the top this namespace was a bit easier to manage but obviously the actions themselves were either larger or the beans they used were larger, for us the actions. For another larger project we went for breadth as we didn't have much that was reusable and therefor had many many actions all acting on the data but in different unique ways. Therefor the namespace we defined was more in line with suggestion two. One standard we have imposed which I think works and looks much cleaner is the /do/* instead of *.do. It requires less explaining to people on what is a .do file ... hehhe ... and it has less legacy implications like.cgi and .pl have ... a namespace is nothing more then a mapping to a resource, therefor extension has less importance. Anyhow ... we use /do/* for all actions.

In looking at the current DiskMultipartRequestHandler I can't tell whether or not the request that is handed and parsed by the MulitpartIterator is already uploaded and complete or is still maybe uploading. Since it is reading a stream I assume that the request may not be complete yet. Is this correct? Use case, user wants to upload a 10MB file. This posting of that file kicks off a MultipartRequestHandler of some kind ... is that file already 100% ready when it gets to that point or is it still uploading? MultipartIterator does all the work of parsing the multipart/form-data representing a file upload with form elements. Each time you call on getNextElement(), it reads a little more from the stream. When getNextElement() returns null, you've reached the end of the stream. 2. My thought process would be to modify the handleRequest method in the DiskMultipartRequestHandler to create some CustomMultipartIterator who's createLocalFile method (if I were to name it simular to the current iterator) would instead of creating a local file open a connection to that other server and begin transfering the bytes as they are read in. Anyone see any holes in this? You might just want to implement the MultipartRequestHandler interface instead of extending DiskMultipartRequestHandler, there doesn't seem to be much functionality in the DiskMultipartRequestHandler that you need. I don't see much gain from extending MultipartIterator, as currently it's pretty File-centric. I'll keep this in mind when I go to recode some of it, but for the time being, it looks like you might be writing your own class to parse the multipart/form-data request body. -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Re: Poolman Help?
Jason B Menard wrote: Without examining your code it is hard to say exactly where the problem is, but basically it doesn't sounds like something is going on with your Connection object (reusing it when you shouldn't, goes out of scope, not closing it when you should, something along those lines). The reason it works after you wait awhile is probably that the connection or the user eventually timesout, as specified by values in your poolman.xml file. Well... This particular problem only exists when I use PoolMan 2.1b1, with nativeResults=false. With nativeResults=true, I get different errors. With PoolMan 2.04, I get different errors yet, apparently because the ResultSet thinks I'm using ResultSet.TYPE_FORWARD_ONLY when I specifically set it to ResultSet.TYPE_SCROLL_INSENSITIVE. Go figure. I agree, the exception would seem to point to me doing something wrong in my code, but I've checked it many times. I only close the connection in a finally block, which means it only gets closed when I'm done with it. It's not a scoping problem. Sometimes after the initial login, I can never login again (due to the same exception) no matter how long I wait. The code works fine without a connection pool and with Oracle's default connection pool. At this point, I've pretty much given up on PoolMan.

Except for a HTML designer, most of the programmers are involved with backend programming. They have done very little HTML work. I was wondering if we will be able to create JSP's using Struts HTML tags and other tag libraries if a form is defined using pure HTML. If the Java Engineers will also be doing alot of the HTML coding, I'd recommend looking at Tiles early in the project. This lets you treat blocks of markup (both template and dynamic) like methods in a program. This can severely reduce the amount of markup the engineers actually have to touch. Instead they incorporate it by reference, much like calling a block of methods. So, with tiles an engineer might create a new Result page by adding this to a configuration file definition name=.item.Result extends=.Result put name=title value=New Item Result / put name=content value=/pages/item/NewResult.jsp / /definition and then just writing the NewResult.jsp segment that exposes the result set (simplified from production, but this would work) logic:notEqual name=RESULT property=size value=0 TRTDTABLE width=100% TR class=greybg THitem/TH THname/TH THcategory/TH THdonor/TH THscript/TH THtype/TH /TR TR TDbean:write name=row property=item//TD TDbean:write name=row property=name//TD TDbean:write name=row property=category//TD TD align=rightbean:write name=row property=donor//TD TDbean:write name=row property=script//TD TDbean:write name=row property=itemType//TD /TR /logic:iterate /TABLE/TDTR /logic:notEqual The rest of the page, headers, footers, menus, even control buttons, can all be inherited from a layout that the HTML dude has crafted.

Re: SSL + URL rewriting problem
Nathan, I have noticed the behavior you describe on a Struts application that I worked on. However, I was not sure of why the :443 was added until your post. I was thinking that it was the web server, perhaps not. Anyway, one issue to watch out for is that Netscape considers these two URLs to be from different servers, and thus won't send the session cookie from one to the other: https://hostname:443/webapp/page.jsp https://hostname/webapp/page.jsp If you are having trouble with people getting redirected back to your login page after they login with Netscape, this issue might be the cause. One solution (that has the significant downside that you have to maintain the setting) is to set the cookie domain for your server. You usually set it to the fully qualified domain name of your web server. The details of how to do that depend on what app server you are using. -Max - Original Message - From: Nathan Anderson [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, February 07, 2002 3:59 PM Subject: Re: SSL + URL rewriting problem I have a bit more information if anyone is interested in helping me with this issue..

Re: Poolman Help?
I have had this same problem with Poolman 2.1b1. In fact I documented with the
author. Here is the e-mail I sent to him:
BRIEF: PoolMan.PreparedStatement is returning null instead of a ResultSet object
after the PoolSkimmer has removed all objects.
DETAIL: This is part of a web based database maintenance program I have developed.
After I start Tomcat and make the first call to the database, PoolMan is instantiated
and operates properly. Any valid SQL I try returns the expected results. However, if
I let a connection become stale and removed from the cache by the PoolSkimmer [so
there are 0 connections in the pool], any PreparedStatement returns the error listed
below. After reverting to PoolMan 2.0.4, the problem is resolved, so I'm assuming
there is an issue with PoolMan 2.1b's PreparedStatement. I have not looked at
PoolMan's code to pinpoint the error more closely. NOTE: I was using the mm.mysql
2.0.6 driver, but it returned a NullPointerException. Once I installed 2.0.9 I got
the error listed below.
