How to pass sql variable from jsp to Action?
I retrieve a group id by JSP. sql:query ...SELECT group_id../ When user clicks a link html:link .../ Before another page is shown, in my struts-config.xml, I try to make a ActionForward function to capture the group_id and then update a session attribute . Then the resulting jsp is like this sql:query SELECT someValue FROM .. WHERE group_id = ???groupId??? / Is this a proper way to do this?

DAOs in service methods
Hey guys. I have alot of service objects called from Struts, and each have a good deal of service methods. Service methods mainly do business logic and talk to DAO objects. Question: I've taken the approach of service methods having the responsibility of instantiating DAO objects locally and using them. Is this correct? Or should I instantiate all the DAO objects that could ever be needed in my service constructor, and use them as instance variables? Or is there a better design? Thanks!

writing a FWRequestProcessor

information for the user (what is usually done within the action with
context.addErrors(...)). So I wonder if there a way to access the context of the
action forwarded to in the request processor?

It does not. Frankly, this is a limitation of the BeanUtils design
model. It assumes for any given process (instance of BeanUtils), a
single conversion strategy applies to all objects of a given type.
I have solved this sometimes by writing a Converter which expects a
few specific variations of a date format and then tests the string
length to look up the format string -- obviously this is imperfect,
but it may work for you.
(something like this:
if (str.length() == 10) {
// parse date using mm/dd/
} else if (str.length() == 8) {
// parse date using hh:mm a
} else {
throw new IllegalArgumentException(Unrecognized date format);

I have a Select Box that I am populating with the html:options tag The result is: select name=cmbGroup id=groupList option value=jk12341Group 1/option option value=34t1fv1Group 2/option option value=32fq21Group 3/option ... /select I need the value for DAO actions performed from the search which will return a detail bean for display on an output JSP. On the output JSP I need to Display the Group Name that I selected from the input. My Form holds the group id and a field for the group name. The options that I can see are: 1. Requery the Database for the output page to retrieve the name given I have the key. This would work, but seems like a lot of overhead to go to the database each time. 2. Create a delimited value (ie option value=jk12341, Group 1Group 1/option) and use the String Split to get the value and label. (I am leaning toward this) 3. use javascript to update the field each time the select changes. The problem with this is that the select box can be very large based on the users selections on previous entries. 4. Store the Value Label list in the session (Don't like this at all because the volume of users that will use this application). Any other suggestions?

I use eapps (http://www.eapps.com) to host my sites, and I'm very happy with them. They offer a true Virtual Private Server (VPS), which means I have my own server, on which I even have root access to modify it as I see fit.

RE: Struts-Tiles Design question
Hi, Just a follow question to a similar scenario, what's the recomended approach with Struts-Tiles to handle the different modes in which a JSP may be displayed. i.e. Add/Edit/View especially for say a JSP page which has multiple sections. e.g. Dish.jsp which can be composed of multiple sections, such as summary.jsp, picture.jsp, ingredients.jsp, preparation.jsp, cost.jsp Here are the approaches I can think of:- 1. Tile Definition say dish.content which has all the JSPs inserts for the dish.jsp page, and each section's (summary/picture/ingredients/preparation/cost) JSP expectinig some request attribute say mode to determine how to display that individual section in Add or Edit or View mode. definition name=main.dish path=/jsp/layout/classicLayout.jsp put name=header value=/jsp/dish/header_dish.jsp/ put name=body value=dish.content/ /definition definition name=dish.content path=/jsp/layout/columnsLayout.jsp put name=numCols value=1 / putList name=list0 add value=/jsp/dish/summary.jsp / add value=/jsp/dish/picture.jsp / add value=/jsp/dish/ingredients.jsp / add value=/jsp/dish/preparation.jsp / add value=/jsp/dish/cost.jsp / /putList /definition And say in the DishAction class doing the forward to the tiles definition say main.dish and passing the request attribute say mode having value edit, view and so on... 2. Having the JSP pages for each section split further as separate JSPs for each mode say summary_add.jsp, summary_edit.jsp, summary_view.jsp and using multiple tile definitions having the same layout!!! such as below:- definition name=main.dish.edit path=/jsp/layout/classicLayout.jsp put name=header value=/jsp/dish/header_dish_edit.jsp/ put name=body value=dish.content.edit/ /definition definition name=main.dish.view path=/jsp/layout/classicLayout.jsp put name=header value=/jsp/dish/header_dish_view.jsp/ put name=body value=dish.content.view/ /definition definition name=dish.content.edit path=/jsp/layout/columnsLayout.jsp put name=numCols value=1 / putList name=list0 add value=/jsp/dish/summary_edit.jsp / add value=/jsp/dish/picture_edit.jsp / add value=/jsp/dish/ingredients_edit.jsp / add value=/jsp/dish/preparation_edit.jsp / add value=/jsp/dish/cost_edit.jsp / /putList /definition definition name=dish.content.view path=/jsp/layout/columnsLayout.jsp put name=numCols value=1 / putList name=list0 add value=/jsp/dish/summary_view.jsp / add value=/jsp/dish/picture_view.jsp / add value=/jsp/dish/ingredients_view.jsp / add value=/jsp/dish/preparation_view.jsp / add value=/jsp/dish/cost_view.jsp / /putList /definition And the having the DishAction class forward to appropriate tiles definition main.dish.edit or main.dish.view..but in this case we are duplicating the Tile definitions even though the page layout is exactly the same!!!

Re: DAOs in service methods
As Leon said, there probably isn't any one right answer, although I think it's fair to say that best practices is as Leon says, to *not* create a DAO per service method. What I tend to do, and I'm not claiming this is any more right than anything else, is to have a DAO factory where I get my DAOs from. It is the factory's responsibility to get a database connection from the pool and hand it off to the DAO. In this way I can have a single factory and get multiple DAOs from it, each sharing the same database connection. The factory I instantiate for each request, so if I use 10 DAOs during a single request, it's still only a single database connection. Using something like iBatis or Hibernate would in effect take the place of the factory and should deal with these concerns for you, but I have not yet used either product in a production app, I've always done it myself (getting away from that!).

Re: Error: Cannot forward after response has been committed?
Ok...
Assuming you have a tiles layout definition like:
definition name=.basic.layout path=/common/mainLayout.jsp
put name=header value=/common/headerTile.jsp /
put name=content value= /
put name=footer value=/common/footerTile.jsp /
/definition
You can make the header content a tile definition by itself, and use that
definition to declare your Controller class, which will be the one with the
logic for forwarding:
definition name=.basic.layout path=/common/mainLayout.jsp
put name=header value=.basic.layout.header /
put name=content value= /
put name=footer value=/common/footerTile.jsp /
/definition
definition name=.basic.layout.header page=/common/headerTile.jsp
controllerClass=my.package.HeaderController
/definition
And put the forward inside the HeaderController class:
public void execute(ComponentContext tileContext, HttpServletRequest
request,
HttpServletResponse response, ServletContext servletContext) throws
Exception {
HttpSession session = request.getSession(false);
if(null == session || null == session.getAttribute(loginForm)) {
response.sendRedirect(/index.jsp);
}
}
Also, make sure that your '/common/mainLayout.jsp' page doesn't have any
html code before the tiles:insert attribute=header / invocation, or it
will make a response being sent to the client.
Regards.

Re: Select Options Question
I'm not sure I understand... do you just need to have the group name when you display the detail for the selected item, or do you need the entire select list (to avoid getting it from the datavase each time?)

May or may not work depending on the flow of your app, but it would be a nice, simple solution if it'll work... just remember to clear it out at an appropriate time.

Re: DAOs in service methods
Actually, the iBATIS DAO stuff works well with darn near any data access technology - sqlmaps, hibernate, jdbc, and about 5-6 more out-of-the-box, so don't think that using the iBATIS DAO means you have to use iBATIS SQL Maps - they are very seperate tools. What it does is similar to what you are describing - it creates a Map of DAO implementations that are keyed by the interfaces for them. One assumption that it does make is that the DAO implementations are thread-safe. It will also allow you to use the implementation as the key, but IMO this is not the best practice. Anyway, you can define an AccountDao interface with the basic CRUD operations, then implement that interface using any data access technology you prefer. Then you use the iBATIS DaoManager to get (shared) instances of those DAO classes. It will also help manage transactions, too. Larry On 9/1/05, Frank W.

Re: Select Options Question
You can also build a javascript array of the descriptions. When the user selects the option from the list, execute a javascript function that will do a lookup for the description in the array and set a hidden form field with the description found in the array. It may happen that the character you use to delimit the key and value will end up in the value and then the fun starts !

May or may not work depending on the flow of your app, but it would be a nice, simple solution if it'll work... just remember to clear it out at an appropriate time. The other option that comes to mind immediately is indeed to use Javascript... seems like all you'd need is a form with two hidden fields, groupName and value... onChange of the select, populate those two fields and submit() the form. You'd then have both pieces of information to render your detail page. Or maybe I don't understand the problem?

Create a delimited value (ie option value=jk12341, Group 1Group 1/option) and use the String Split to get the value and label. (I am leaning toward this) 3. use javascript to update the field each time the select changes.

Re: DAOs in service methods
Sounds quite cool :) Unfortunately, I already lost the argument at work to use iBatis instead of Hibernate. Hibernate isn't bad, but I would have preferred iBatis. Oh well. Frank Larry Meadors wrote: Actually, the iBATIS DAO stuff works well with darn near any data access technology - sqlmaps, hibernate, jdbc, and about 5-6 more out-of-the-box, so don't think that using the iBATIS DAO means you have to use iBATIS SQL Maps - they are very seperate tools. What it does is similar to what you are describing - it creates a Map of DAO implementations that are keyed by the interfaces for them. One assumption that it does make is that the DAO implementations are thread-safe. It will also allow you to use the implementation as the key, but IMO this is not the best practice. Anyway, you can define an AccountDao interface with the basic CRUD operations, then implement that interface using any data access technology you prefer. Then you use the iBATIS DaoManager to get (shared) instances of those DAO classes. It will also help manage transactions, too. Larry On 9/1/05, Frank W. Zammetti [EMAIL PROTECTED] wrote: As Leon said, there probably isn't any one right answer, although I think it's fair to say that best practices is as Leon says, to *not* create a DAO per service method. What I tend to do, and I'm not claiming this is any more right than anything else, is to have a DAO factory where I get my DAOs from. It is the factory's responsibility to get a database connection from the pool and hand it off to the DAO. In this way I can have a single factory and get multiple DAOs from it, each sharing the same database connection. The factory I instantiate for each request, so if I use 10 DAOs during a single request, it's still only a single database connection. Using something like iBatis or Hibernate would in effect take the place of the factory and should deal with these concerns for you, but I have not yet used either product in a production app, I've always done it myself (getting away from that!).

Re: DAOs in service methods
Hi, my suggestion would be to have a closer look at the Spring framework. IoC / dependency injection is really cool once you get a grasp of it. Instead of having the service look up a DAO instance, you simply inject the fitting implementation class into the service via Spring. The service itself only knows the DAO interface and has a setter property for it. Note that this way you also have to deal with shared instances (like with iBATIS DAO) and therefore have to keep heed of thread issues, but luckily Spring also provides template implementations for most common database access solutions (JDBC, iBATIS, Hibernate, JDO, Toplink (by Oracle) which are said (I still have to check that out) to be inherently thread-safe. Btw. can anybody here confirm this?

Re: Specifying MessageResource for Title information.
one way is to define a CustomMessageResources and a CustomMessageResourcesFactory to take care of this. The basic idea is that we would define something like this in the struts-config.xml message-resources parameter=hints,otherhints,ApplicationResources factory=com.a.b.c.CustomMessageResourcesFactory null=true/ and let our CustomMessageResources in it's loadBundle method parse the parameter with the , delimiter and loadBundles for all the properties files. One thing to note here would be that although they would be different properties files for us, it would get compiled as a single Map so, any properties with the same key will get silently overridden. (having a unique prefix for a given property file should take of this) Take a look at http://javaboutique.internet.com/tutorials/Dynaform/index-7.html Although the author overrode the Servlet there in his implementation, just providing a new factory to create your Custom Message Resources should suffice.

Specified RequestProcessor not compatible with TilesRequestProcessor
I am integrating Struts into an existing web application. It seemed like a good idea to have our custom RequestProcessor extend org.apache.struts.tiles.TilesRequestProcessor rather than org.apache.struts.action.RequestProcessor, so we would have the option of using Tiles. However, when I change the struts-config.xml controller tag to: controller processorClass=com.med.struts.action.CustomRequestProcessor/ where previously it had been: controller processorClass=org.apache.struts.tiles.TilesRequestProcessor/ I get the following errors if the CustomRequestProcessor extends the TilesRequestProcessor and the application is configured to use the Tiles tab library and plug-in: org.apache.struts.tiles.TilesPlugin TilesPlugin : Specified RequestProcessor not compatible with TilesRequestProcessor org.apache.struts.action.ActionServlet Unable to initialize Struts ActionServlet due to an unexpected exception or error thrown, so marking the servlet as unavailable.

RE: custom date converters

When you say -
this is a limitation of the BeanUtils design
model. It assumes for any given process (instance of BeanUtils), a
single conversion strategy applies to all objects of a given type.
Do you mean that the converter applies thru my all application?
As much as I know - copyProperties() is a static method of BeanUtils so
I'm don't really know where (if at all) BeanUtils is instanciated.

It does not. Frankly, this is a limitation of the BeanUtils design
model. It assumes for any given process (instance of BeanUtils), a

I have solved this sometimes by writing a Converter which expects a
few specific variations of a date format and then tests the string
length to look up the format string -- obviously this is imperfect,
but it may work for you.
(something like this:
if (str.length() == 10) {
// parse date using mm/dd/
} else if (str.length() == 8) {
// parse date using hh:mm a
} else {
throw new IllegalArgumentException(Unrecognized date format);

Hm...IMHO one good example would be the JPetstore sample app that comes with the Spring distribution, for instance. Good in particular, as its not overly complex, plus you can compare it to the 'traditional' iBATIS JPetStore app. The architecture has slightly changed (the former 'service' functionality now rather completely wandered underneath 'domain.logic', in the Facade implementation, which is IMHO ok in this case, as it's mostly delegating everything anyway). This is one of the samples I profited the most from when evaluating Spring. Another good starting point would be Matt Raible's AppFuse, which is basically for Hibernate and a little bit more complex. Those two are kind of my 'reference samples' when it comes to Spring :-) Note that in both cases, the DAOs are very lean and don't contain any messy synchronization code. But IMHO the really cool thing about IoC (not to mention the AOP functionality) is that you finally can achieve really loose coupling throughout your entire app, and its simple. In fact, we could replace virtually anything in our current app by a different implementation, declaratively (apart from providing the new implementation class, implemen- ting the same interface). Another benefit is that Spring is non-intrusive by design and you can happily stick to the technology stack you already know it works. For instance, we still use Struts/Tiles instead of Spring MVC or JSF.

Re: Tech-Stack Choices
You are likely to hear many differing opinions on this list. You should evaluate your criteria. Are you wanting something slick? Fast development? Easier maintenance? Scalable? Flexible? If you are wanting something fast. Take a look at Ruby on Rails, or stay tuned to this channel for updates on Struts Ti. If you want to leverage your existing team's talent (based on your comment below), stay with Struts. If you have to hire new help, you will find the largest talent base has Struts experience over anything else we've mentioned. If you are wanting something standard (as in J2EE standards), I'd say go with JSF.

re: Tech-Stack Choices
As james said it in his first reply, you should become clear what you need and what you want. How critical and how important is it for the company? If it is important or even critical for the core business of the company (or say if it doesn't work, it costs 100.000 per hour) I would engage you to write it by yourself. Otherwise it can happen to you, that features you considered important are droped down from the framework or your technological or organizational direction is considered obsolete. There is always a risk factor working with open source projects (there are chances too), but the biggest problem is, that you just have noone to kick in the ass if something is broken. By the way, the abovementioned direction cut seem just to happen to us (with struts) so we are thinking about abandoning it, but thats a different story. If it's not THAT important, you should still choose something which isn't just in the first release. Talking about frontend I wouldn't even think about JSF or SHALE, since they are extremely new. Struts 1.2.7 is believed to be a high quality, stable product, so it could be a very reasonable option, but you should test it yourself first. Moving along the application, for the mid-tier spring or pico-container seem to be the best available choice. On the other hand, what's wrong with your POJOs? Do you really need a container? Spring is a lightweight container, but it's still a container. My first choice would be POJOs, as you already seem to have, and in case you need distribution CORBA or RMI (last if performance isn't an issue). For the persistence layer, there are many frameworks available, iBatis and Hibernate among them. I don't know enough about your application to give you reasonable advices (which I normally bill by 100$ per hour :-)), but I think you should make a requirement analyses and compare the frameworks. Since you already work with XML on the persistence side (my interpretation of a custom built XML based data access layer) you maybe should look into XML-DBs. After all, you should really invest some time into proper requirements analysis to make the right decision, based on your requirements and not someone else's preferences.

Re: Tech-Stack Choices
I hit send too soon Just to be clear, Spring and Hibernate are really irrelevant in the context of this discussion, unless you mean Spring MVC. I can't speak for Spring MVC, so I'll let others discuss the merits. My professional opinion (if it means anything) is to go with Spring/ Hibernate no matter which choice of web framework you decide. The benefits you get with O/R and IoC *far* outweigh any learning curve that you may encounter. I think anyone who's been down that road would agree.

From: Nirmala Dhara [EMAIL PROTECTED] %@ taglib uri=struts/bean-el prefix=bean % %@ taglib uri=struts/html-el prefix=html % org.apache.jasper.JasperException: File /struts/bean-el not found I suggest removing the taglib tags from web.xml, and using the URIs found in the tld files themselves (which are stored in struts.jar and struts-el.jar). The tlds can be found within the .jar files, there's no longer any need to store them loose under WEB-INF and configure them in web.xml. Try: %@ taglib uri=http://struts.apache.org/tags-html-el; prefix=html % %@ taglib uri=http://struts.apache.org/tags-bean-el; prefix=bean % (As for the original question, I wonder if either the TLD files are not under WEB-INF, or if in one JSP you have uri=/struts/bean-el with a leading slash.) -- Wendy Smoak - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Trim all fields before validation
Sounds good. I certainly understand the jitters, my organization is
very much like that as well (in fact, I had to sneak some JWP code in
too, disguised as part of the app itself!) Just wanted to know if there
was a problem with it that I could have done something about. As always
though, I very much appreciate any feedback, so if you do have any
suggestions down the road, I'll be here :)

I did try a generic loop as per Joe's suggestion and that worked
pretty well. Here is a what I did.
java.util.Map map = thisForm.getMap();
java.util.Iterator it = map.keySet().iterator();
while(it.hasNext()){
String key = (String) it.next();
Object obj = map.get(key);
if (obj instanceof String){

else if(obj instanceof String[]){

obj = temp;

Wouldn't this be easier, without mucking with the form, to let this be
handled by the validator itself. For any field validation you would
just
have to have the requires validation before you do any other
validation,
and that way you would take care of empty strings or as Joe said you
could
do this in javascript as well pretty easily.

Tiles: Unique body attributes for each part.
Sorry if this got posted twice. Hi I'm new to Struts and Tiles, but I was able to build a basic web application that worked fine. Tiles def was pretty standard with header, body, footer, etc My problem now is that I'm required to use a more advanced header. They gave me a header.jsp page to use and it has it's own body tag with a backgroud attribute assigned to an image. When I just replace my old header.jsp page with the new one, no background image is displayed on my header. Instead it seems to display on my body page instead. I think tiles is combining all my pages so that I can only have one body tag. IE: start a body tag in the header and end the body tag in the footer. Is their a way to assign unique body attributes for each part of my tiles?

seems to work:
protected void processPopulate(HttpServletRequest httpServletRequest,

ActionMapping actionMapping) throws ServletException

super.processPopulate(httpServletRequest, httpServletResponse,

Map.Entry entry = iterator.next();
if (entry.getValue() instanceof String)
dynaActionForm.set((String)entry.getKey(),
((String)entry.getValue()).trim());
}

}
Is there something I'm missing?

Re: Error: Cannot forward after response has been committed?
Thank you so much.
2005/9/1, Guillermo Castro [EMAIL PROTECTED]:
Ok...
Assuming you have a tiles layout definition like:
definition name=.basic.layout path=/common/mainLayout.jsp
put name=header value=/common/headerTile.jsp /
put name=content value= /
put name=footer value=/common/footerTile.jsp /
/definition
You can make the header content a tile definition by itself, and use that
definition to declare your Controller class, which will be the one with the
logic for forwarding:
definition name=.basic.layout path=/common/mainLayout.jsp
put name=header value=.basic.layout.header /
put name=content value= /
put name=footer value=/common/footerTile.jsp /
/definition
definition name=.basic.layout.header page=/common/headerTile.jsp
controllerClass=my.package.HeaderController
/definition
And put the forward inside the HeaderController class:
public void execute(ComponentContext tileContext, HttpServletRequest
request,
HttpServletResponse response, ServletContext servletContext) throws
Exception {
HttpSession session = request.getSession(false);
if(null == session || null == session.getAttribute(loginForm)) {
response.sendRedirect(/index.jsp);
}
}
Also, make sure that your '/common/mainLayout.jsp' page doesn't have any
html code before the tiles:insert attribute=header / invocation, or it
will make a response being sent to the client.
Regards.

Where the Tiles Controller belongs to?
Does it stick one layout?
Thanks
2005/9/1, Guillermo Castro [EMAIL PROTECTED]:
The error happens when part of your jsp page has already been sent to
the
client.
My recommendation would be to define a Tiles Controller (see
org.apache.struts.tiles.ControllerSupport) that would do the forwarding
logic.
I hope this helps.

Within a Tiles layout,
I try to forward to another jsp when a bean not exist?
But it leads to the subject line error message?
In the header layout jsp, I put this
logic:notPresent scope=session name=loginForm
jsp:forward page=/index.jsp/
/logic:notPresent
If it is not allowed or it is not a good way,
what is the better way or another way to do so?

Re: How to pass SQL variable from JSP to Action?
I just read the Struts user guide again.
Is it the right track to go?
In Action:
ResultSet rs = ...;
ResultSetDynaClass rsdc = new ResultSetDynaClass(rs);
Iterator rows = rsdc.iterator();
while (rows.hasNext()) {
DynaBean row = (DynaBean) rows.next();
... process this row ...
}
rs.close();
In JSP:
logic-el:iterate name=stringbean property=stringArray id=foo
indexId=ctr
html-el:text name=stringbean
property=labelValue[${ctr}].label /
/logic-el:iterate

Betreff: Re: How to pass sql variable from jsp to Action?
I wonder if it is a proper way to do it because
the 1st query displays a no of rows with different group ids.
Can the html:link pass a value to Action?
If it can, it is excellent.
Should it be done like this?
change the layout from a no of links html:link
to a no of forms html:form
In each form, it has hidden value of group id.
How will you do this? Thank you very much for your help.
2005/9/1, 梁炳�� [EMAIL PROTECTED]:
I retrieve a group id by JSP.
sql:query ...SELECT group_id../
When user clicks a link
html:link .../
Before another page is shown, in my struts-config.xml,
I try to make a ActionForward function to capture the group_id
and then update a session attribute .
Then the resulting jsp is like this
sql:query SELECT someValue FROM .. WHERE group_id = ???groupId??? /
Is this a proper way to do this?
I do not know how to write in the Action class so that
it can retrieve the sql value from the passing in jsp file.
Your help is very much appreicated.

Re: Tiles: Unique body attributes for each part.
Hi, that sis a limitation of html. You con nota have more than one body in the same document. The only sokution u can see is using frames, or replacing de body t ag by a div tag, apllying a styke with the background settings... i wish it helps Lucas oracle411 [EMAIL PROTECTED] escribió: Sorry if this got posted twice. Hi I'm new to Struts and Tiles, but I was able to build a basic web application that worked fine. Tiles def was pretty standard with header, body, footer, etc My problem now is that I'm required to use a more advanced header. They gave me a header.jsp page to use and it has it's own body tag with a backgroud attribute assigned to an image. When I just replace my old header.jsp page with the new one, no background image is displayed on my header. Instead it seems to display on my body page instead. I think tiles is combining all my pages so that I can only have one body tag. IE: start a body tag in the header and end the body tag in the footer. Is their a way to assign unique body attributes for each part of my tiles?
