AW: Struts vs Jade
Hi, in my opinion Jade is really something for webdesigners. I think struts has a handicap on the view development. There should be a more intensive cooperation to include the struts taglibt into products like Dreamweaver. There is a smart support yet, but it doesn't work really. I think the handling on the view layer has to be improved. I work since 1 year with struts, but the view layer brings always some problems with. For the view layer are the features supported by Jade (if really) better. But I would hear a meaning by someone, who has done something with Jade. I don't know anyone.

RE: I am not able to call a method in the Action Class
Hi Sriram, What error message are you getting? You say you are calling the method from the onChange event, so I presume in the onChange you submit the form ,and then in a method of your action try to call this other method that doesnt work, OR is this method the one that is supposed to be invoked on submit (ie: one of your dispatch action 'execute' methods). In this case you need to ensure that the method parameter (the actual name of this parameter is defined in your struts-config.xml) is set correctly to the name of the method you are trying to call (by appending it to the action url or having it in a hidden form field), and that the signature of your method is the same as that of the execute method. -Andrew -Original Message- From: Sriram R [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 10, 2002 16:42 To: [EMAIL PROTECTED] Subject: I am not able to call a method in the Action Class Hi, I am not able to call a specific method in the Action class which extends DispatchAction I am geeting this problem only if i try to call the action class method using onChnage event of a dropdown.

Re: Tiles without struts
Hi,
You can use Tiles without Struts. If you want also the definition
capability, you need to initialize the Tiles factory. This can be done
by using the TilesServlet (as you do). In this case, Tiles factory
config is specified in web.xml. You don't need the TilesPlugin because
you don't use Struts.
Tiles don't support direct forward to a definition name. Definition
names are logical names. You need to map URLs to definition names. This
can be done in the servlet associated to the mapping mechanism. Map an
extension to your servlet, and in the process() method of the servlet,
do the following:
// Catch the definition name
String definitionName = ???;
// Get the definition (add appropriate catch)
ComponentDefinition definition
= DefinitionsUtil.getDefinition(definitionName, request,
getServletContext());
// Create new Tiles context, initialized with the definition
ComponentContext context = new ComponentContext(
definition.getAttributes() );
// Save context where the tiles will find it
ComponentContext.setContext( tileContext, request);
// Include the tiles
String uri = definition.getPath();
RequestDispatcher rd = getServletContext().getRequestDispatcher(uri);
rd.include(request, response);
Check the TilesRequestProcessor class to know how it is done with Struts.
If you have an interesting forward method that can be added to
TilesServlet and you agree to share it, let us know ...
Hope this help,
Cedric

I have a large existing application that uses a common page layout and would

because there is already a controller in the application, we would like to

From what I've read it seems that we should be able to have the current
forwards, which are mapped in web.xml using url-mappings. The current pages
were mapped using the extension view. I am using the latest struts binary
build and tomcat 4.0. Documentation alludes that you can map urls onto
tiles-defs with the latest release. At the bottom is the request url I
tried and there was no output given in the console, just and error in the
browser The specified HTTP method is not allowed for the requested resource
(HTTP method GET is not supported by this URL). Hopefully someone with
more experience in Tiles could point me in the right direction; all I want
is to move our current view url mappings from web.xml into
tiles-definitions.xml and have tiles assemble the pages using a standard
presentation layout. Thank you for any help you provide.

You can read about it at: http://www.phpbuilder.com/columns/tim2705.php3. Of course, he was using PHP instead of Struts :) The article appears to be lauding MySQL features albeit 1999 on some speed issues. I definitely miss the subselect SQL syntax which is definitely useful with Oracle and Sybase. MySQL 4.0 Beta is out and wait for it. Full Text Match capabilities. Is this the end of Lucene or eSearch ? No. I like the bit about not returning the whole table of data if the query matches more than half the number of rows in the database table. ... I personally think a DBMS should give you what you ask for :-) I've seen enough times when I actually *did* need to pull back that much data, that it would really tick me off if my DBMS made such a judgement call for me. That seems quite arrogant to me ... It should be the developer's job to determine what comes back; not the DBMS's job. As for LargeResultSets I don't think Sybase has rowset limit optimisation. Oracle I know a ROWID reverse keyword or is it ROWINDEX I cant remember. PostgreSQL has this functionality too -- and it's ACID-compliant. For my own personal work I chose PostgreSQL for several features that MySQL - nested queries, views, triggers and stored procedures being the biggies. Transactions weren't available with MySQL at the time I made my decision but, even with their current level of support for transactions, I cannot conceive of doing without the other features, views and stored procedures especially. And that is why I don't understand Sun's push for MySQL. Are there any enterprise level projects (heck, even department level projects) that you don't want to use views and stored procedures with? Sun's push for MySQL. Where did you read about this ? Here's the full story: http://news.com.com/2008-1082-947510.html rjsjr Well ISP / Java WebHoster only support MySQL, so I got no choice. You should (generally) be able to get them to provide you with PostgreSQL too. I'd be shocked if it wasn't already installed. SapDB is quite hot nowadays too, from my understanding. Go with a DBMS that passes the ACID test ... unless you honestly think you don't need all that stuff.

NullPointerException while extending DynaValidatorForm
Hi all, I have a problem setting values of a form in my action. The form extends the org.apache.struts.validator.DynaValidatorForm.

Re: How to user logic:iterate[MORON]
Without the taglib statement, the tag is completely ignored, as if it
wasn't there. The JSP service assumes it's a HTML tag, and the browsers
silently swallow anything they don't understand. C'est la vive.

Re: Security and Struts
They have a good login example in the example war in the struts/webapps dir. That's the way I've done it in the past. The way I'm currently doing it is to use container managed security. This means NOT using struts for authorization/authentication (for J2EE security). Since your using JSP your probably gonna do form base authentication so just post your form to action=j_security_check and make sure your form username and password fields are j_username and j_password appropriately. Check your container documentation for how to hook this into its security model. I'm currently actually having a problem with this in that I need for the user information to be stored in the session at login. I may just put a tag at the top of every page but that seems to get rid of the 'niceties' of using J2EE security. I want to set the locale based upon the loaded user object. Problem is, it goes right to the requested jsp page after login without loading the user and his preferences. Not sure how I'm going to handle this but in the mean time, that is how I handle security.

Here's how you would grab the next set of values: select id, field1, fieldn from table where id cur_value order by id fetch first 30 rows only You would put a number in for cur_value like 30 to get the second set of 30 records.

RE: Improving performance by splitting JSP?
I had to go back and look at the test code we used, but yes - looks like we did try a non-body tag. It did a hashtable lookup for whatever key values was passed in as a parameter. I remember we found that we could only recreate the performance discrepancy with tags that did some kind of memory lookup; just adding loops around arithmetic statements are writing output were tried, but did not exhibit the symptoms.

Yup, we looked at overall size of the JSP as well, and the association with performance was definitely number of bm/bw tags within a single JSP rather than overall JSP size. We even tried editing the generated servlet code and adding big unused methods to see if the problem had to do with generated servlet file size. That would kind've made sense, but was a negative. I believe we also tried a tag that just did a sysout rather than any kind of memory lookup (hashtable or properties file) and found that this performance quirk in the sun vm did not appear in that case. When you wrote your own tags (the message/write equivalents, I mean), did you happen to play with body versus non-body tags? When I was wrestling with the too many tags problem a while ago, I ended up writing my own versions of some of the Struts tags so that they were non-body tags, because they caused noticeably less code to be generated. I didn't measure performance differences, but I wouldn't be surprised to see a noticeable improvement there too. -- Martin Cooper We could never pin down a why, it seemed that the sun 1.3 vm just ran like a snail with a lot of bm or bw tags in a single page, so we stopped doing that ;-). Same number of tags split up into multiple JSPs, or a few tags called the same number of times via a loop - OK performance. It is very true also that splitting them up into smaller bites makes them more readable and maintainable, so it was a good solution all around. It's just that you are always nervous when you fix a problem and don't know the why of it ;-).

deploying a struts application
i have a question on deployment. i am thinking of packaging my application as a war file, and letting the users place this in the right location in their container. the only problem is that there is a config file that needs to be edited prior to the application working. the config file lives in a specific path within the class files. so the users have to un-war the files first to get at the config file, which i think defeats the purpose and convenience of it a bit. is there another standard way to distribute config files so the users can make changes to them at the same time as deployment of the war? any tricks that you all have come across? thanks, mark -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Re: Using global forwards to tile definitions?
The html:link tag can't be used with a Tiles name as path. You need to use an intermediate action.

RE: Question: Configuring Multiple message-resources Elements With Sub-Applications
Whoops! In my examples below, the action tags should actually be action-mappings. That was a cut-and-paste error on my part and not relevant to this problem. I fixed the examples in this reply. -Original Message- From: Hohlen, John Sent: Tuesday, September 10, 2002 11:43 AM To: Struts-Help (E-mail) Cc: '[EMAIL PROTECTED]' Subject: Question: Configuring Multiple message-resources Elements With Sub-Applications If I'm using multiple message resource files with sub-applications, do I need declare all the message resource files in the default struts config file or do I declare each message resource file in the corresponding sub-app's struts config file? I searched the mailing lists, Struts documentation, and the online chapter's in Chuck Cavaness' upcoming Struts book (O'Reilly). I have not found a clear example on how to do this. Example #1 - Declaring All Message Resources In struts-config.xml: = --- struts-config.xml- struts-config message-resources parameter=com.abc.training.Messages null=false/ message-resources key=SUB_APP_A_MESSAGES_KEY parameter=com.abc.training.SubAppAMessages null=false/ /struts-config --- struts-config-sub-app-a.xml- struts-config form-beans ... /form-beans action-mappings ... /action-mappings /struts-config Example #2 - Declaring Each Message Resource In Each Sub App's struts-config-xml: --- struts-config.xml- struts-config message-resources parameter=com.abc.training.Messages null=false/ /struts-config --- struts-config-sub-app-a.xml- struts-config form-beans ... /form-beans action-mappings ... /action-mappings message-resources key=SUB_APP_A_MESSAGES_KEY parameter=com.abc.training.SubAppAMessages null=false/ /struts-config I can't get either approach to work. If I use approach #1, error keys are not properly located for errors placed in the errors container by sub-application A. Hence, error mesages appear as ???en_US.key???. But this approach does work for JSP text retrieved from sub-app A's message resource file (as long as I specify the bundle attribute). If I use approach #2, I get the following exception (WebLogic 6.1 with SP2 or SP3): javax.servlet.ServletException: Cannot find message resources under key SUB_APP_A_MESSAGES_KEY at weblogic.servlet.internal.RequestDispatcherImpl.forward(RequestDispatcherImp l.java:256) at org.apache.struts.action.RequestProcessor.doForward(RequestProcessor.java:10 14) at org.apache.struts.action.RequestProcessor.processForwardConfig(RequestProces sor.java:417) at org.apache.struts.action.RequestProcessor.processActionForward(RequestProces sor.java:390) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:271) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1292) at com.erac.fleetsystems.strutsx.FleetSystemsServlet.process(FleetSystemsServle t.java:178) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:492) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at weblogic.servlet.internal.ServletStubImpl.invokeServlet(ServletStubImpl.java :265) at weblogic.servlet.internal.ServletStubImpl.invokeServlet(ServletStubImpl.java :200) at weblogic.servlet.internal.WebAppServletContext.invokeServlet(WebAppServletCo ntext.java:2495) at weblogic.servlet.internal.ServletRequestImpl.execute(ServletRequestImpl.java :2204) at weblogic.kernel.ExecuteThread.execute(ExecuteThread.java:139) at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:120) I believe approach #2 makes the most sense, but I keep getting the above servlet exception.

RE: jndi as a data source
Here's some code that I wrote to use LDAP through the Commons Pooling
mechanism... I'm still trying to figure out a good way to validate the
connection using the validateObject method, so that part is likely not
optimal.
There are 2 classes:
* LdapConnectionFactory, which implements
BasePoolableObjectFactory
* HRLdap uses the LdapConnectionFactory
Here is the code that then can use HRLdap:
HRLdap ldap = new HRLdap();
ldap.executeCdsIdLookup(cdsId);
String buCode = ldap.getBusinessUnitCode();
...
...
...
I've tried to strip out some stuff that is only applicable in the
environment here, but hopefully this helps.
I'd be interested in anyone else's feedback on this as well in case i'm
doing something stupid =)

RE: Improving performance by splitting JSP?
True. However, Jim encountered this performance problem with the bean:write and bean:message tags provided with Struts as well, and AFAIK they use an unsyncronized FastHashMap, so that wouldn't explain the slow-down he got with lots of write/message tags (that's why they were trying to write their own custom tags to replace them in the first place). peace, Joe -Original Message- From: Hajratwala, Nayan (N.)

The JSP compiler doesn't even issue a warning? That's pretty lame. In the absence of a taglib directive, what looks to you like a Struts tag just looks like template text to the compiler, and it is simply passed through to the response (like all the non-tag HTML markup in a typical Struts-based JSP page). Remember, there is no requirement that the template text look like HTML or XML markup, so there is absolutely no basis on which the compiler can possibly consider this to be an error condition. --joe Craig -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: Improving performance by splitting JSP?
Our test tag was using a HashMap. You can view this performance quirk yourself using Struts bean:message tag. To get orders of magnitude in the performance discrepancy (to make sure we were measuring the tag performance difference on a much more significant scale than server access variance times) we went to 200,000 tag exectutions done a variety of ways: One of our cases was a page with 20 tags, inside a loop 10,000 times. Another case was same page, but done by 160 tags inside a 1250 loop. Another case same page rendered by includes: page included another page 8 times inside a 1250 loop. The included page had 20 tags. There were other varieties, but these three show the discrepancy in performance with the increased number of tags very significantly. All three cases output the same resulting html. All three cases executed the tag code 200,000 times. The first and third cases, with 20 custom tag occurrences, performed roughly the same (better performance). The second case with 160 tags performed much much worse. I don't have our statistics anymore, alas, but it was two or more orders of magnitude worse. We tried an 80 tag variety as well, and it put the expected point on the slope (significantly worse than same output rendered via 20 tags, not as bad as 160 tags). Switching to IBM VM, or turning profiling flags on in the Sun VM before running the tests, caused the performance discrepancy between these approaches to vanish (roughly the better performance mark for all three). Be wonderful if someone else could verify on their own. Two days of cursing over it was enough for us ;-). As soon as we realized we could fix the problem pages by restructuring them into separate JSPs, we declared victory over the Mystery of the VM ;-).

struts basic question
Hi, I have a question about defining a html:form.. on my jsp page, 1. suppose i define a form like below in my selectenv.jsp html:form action=/pages/selectenv do i have to have a bean-form defination in my struts-config file like below form-bean name=selectEnvForm dynamic=true type=org.apache.struts.validator.DynaValidatorForm form-property name=envDrop type=java.lang.String/ /form-bean 2 . can i define a form with action as blank like html:form action= and then have a javascript which will define value for action, 3. If my old html form looks like this form name=myform action=env.jsp what would be struts equivalent, if i define a name for the form it gives me error, that a type must be assigend, and when i give type as org.apache.struts.validator.DynaValidatorForm, it gives me class cast exception error. for the above form defination Ashish = A$HI$H __ Yahoo! - We Remember 9-11: A tribute to the more than 3,000 lives lost http://dir.remember.yahoo.com/tribute -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

[Announce] [New Extension] ApplicationResources.properties from Database
For anyone interested, I have finished implementing DBMessageResources which allows you to keep the key-value pairs (from your ApplicationResources.properties) in a single database table. You can load your property files into a table (generic schema is provided) and with this extension, by only modifying message-resources in the struts-config.xml your application will run WITHOUT ANY code changes. (See the readme.txt file included) This extension uses OJB (http://jakarta.apache.org/ojb) O/R mapping for database configuration and connection pool management. I have included a modified version of the (1.1b2) struts-example to demonstrate. I have tested this with Struts 1.1b2, and I'm sure it will work with 1.1b1 (If anyone requires a 1.0.x compatible, I can look at that also) I will get this project available as soon as I work through some cvs issues on sf.net: If anyone is REALLY itching to get their hands on it sooner, send me a email. For those who were waiting, thanks for your patience.

RE: Improving performance by splitting JSP?
It would also be interesting to try different JSP page compilers, which would also make a huge difference - for example, Jasper2 (used in Tomcat 4.1.x) versus the original Jasper in Tomcat 4.0. On the Sun JVM, one additional variable is to try the -server system property at startup time for your container. This selects the HotSpot mode optimized for long-running server applications, versus the default -client setting.

Our test tag was using a HashMap. You can view this performance quirk yourself using Struts bean:message tag. To get orders of magnitude in the performance discrepancy (to make sure we were measuring the tag performance difference on a much more significant scale than server access variance times) we went to 200,000 tag exectutions done a variety of ways: One of our cases was a page with 20 tags, inside a loop 10,000 times. Another case was same page, but done by 160 tags inside a 1250 loop. Another case same page rendered by includes: page included another page 8 times inside a 1250 loop. The included page had 20 tags. There were other varieties, but these three show the discrepancy in performance with the increased number of tags very significantly. All three cases output the same resulting html. All three cases executed the tag code 200,000 times. The first and third cases, with 20 custom tag occurrences, performed roughly the same (better performance). The second case with 160 tags performed much much worse. I don't have our statistics anymore, alas, but it was two or more orders of magnitude worse. We tried an 80 tag variety as well, and it put the expected point on the slope (significantly worse than same output rendered via 20 tags, not as bad as 160 tags). Switching to IBM VM, or turning profiling flags on in the Sun VM before running the tests, caused the performance discrepancy between these approaches to vanish (roughly the better performance mark for all three). Be wonderful if someone else could verify on their own. Two days of cursing over it was enough for us ;-). As soon as we realized we could fix the problem pages by restructuring them into separate JSPs, we declared victory over the Mystery of the VM ;-).

Re: Tip #1
You'd need a descendant of ActionForm, yes. It would have a property for each image button (an instance of ImageButtonBean) that you needed to have on your form. It kind of yanks dyna-forms out from under you a little bit. I'm not entirely sure, but possibly you could specify a formbean that descended from the dyna* stuff and had your button properties -- which could be reused and still have dynamic fields as well. I'd have to dig and I'm kind of in the middle of something else right now :-( Sorry. I didn't see your reply or I'd have answered sooner. The most straight-forward implementation would build a new ActionForm descendant that had properties for each of your required fields, and a property for each button - yes.

I believe with tomcat you can set this up with context entry pointing to some random directory. If you want to reference the MP3s via Java, I used a property file to indicate the directory the my mp3s are stored in along with the virtual reference from the new Tomcat Context. This is essentially the same as having two web applications. One being deployed as an ear and one as an web application with its document root as a directory reference to the mp3 collection. The only draw back I found to this is that tomcat treats mime mappings somewhat strangely. .MP3 and .mp3 are not equal. .mp3 returns the right mime mapping and .MP3 was returned as an octet string.

% if(request.getSession().getAttribute(User) != null) { % is same as
logic:present name=User scope=session, is it right? If it is right,
why the former works, but the latter does not.(I have the line %@ taglib
uri=/WEB-INF/struts-logic.tld prefix=logic % in my jsp file).
Cn someone give me an example on how to use logic:present? I searched from
web, I can't find a specific example including the usage of logic:present.
Thanks,

Hi, all:
I want to use logic:present to check if user has logon.
If I use % if(request.getSession().getAttribute(User) !=
null) { % .
it works fine. but I change it to use logic:present. I changed it to
logic:present name=User scope=session...
/logic:present. But it
never evaluate logic:present... as true. Am I doing
somethig wrong here?

Re: ActionError question
You could have an entry in your properties file like error.generic={0}
Then use new ActionError( error.generic, The legacy error message );
That what you were looking for?

Re: Using global forwards to tile definitions?
On Tue, 2002-09-10 at 19:33, Cedric Dumoulin wrote: Yes, the problem comes from html:link. It is not a bug: Tiles definitions name are logical names, not URLs. html:link require a real URL to work because its result is interpreted on the server side. The tag is processed on the server side but the actual result is an URL which get sent back to the client within the HTML. That leads me to think that the tag can generate a 'normal' URL from a symbolic name perfectly well. Cedric [EMAIL PROTECTED] wrote: Well, that does help.

The html:link tag can't be used with a Tiles name as path. You need to use an intermediate action. An often used solution is to have an action taking a definition name as http parameter, like the tiles DefinitionDispatcherAction. This action should check if the provided definition name is allowed, otherwise it is possible to access all your definitions. Your global forward could now look like: forward name=home path=path.to.dispatcheraction.do?def=plantsec.index/ Hope this help, Cedric [EMAIL PROTECTED] wrote: I'm going back and trying to implement some best practices that I skipped over in the beginning.

The Shifting Session Action.LOCALE_KEY Value Mystery -- Sleuths Welcome!
I use the following page to set the session Action.LOCALE_KEY to some
language. (I know, it could be done differently.) This works great except
I get the correct Action.LOCALE_KEY value for every page except
index.jsp. Why would that be? I had this configured before so the index
page also worked.
Now, if I set the language to, say lang=ko, it works in every page but the
index page and the index page shows that the session object is different
than the session object is on every other page. That is nutty. Anyone
have an idea?

Re: The Shifting Session Action.LOCALE_KEY Value Mystery -- Sleuths Welcome!
On this situation, if the index page is in another language, it works on
the index.jsp page fine, i.e., if I set my browser to Italian, Chinese,
etc. it will show up correctly.

Session Values for Action.LOCALE_KEY Change
I set the session locale in a language.jsp page with: session.setAttribute(Action.LOCALE_KEY, new Locale(language)); where language is a return from a form parameter locale via: String localeValue = request.getParameter(locale); String language = localeValue.substring(0, 2); This works on all pages, except the index.jsp page. I can set the language variable to ko and the entire site will stay on Korean, but when I go to the index.jsp page, it is back to English. If I go from the index.jsp page back to the other pages, they stay in Korean. I am very puzzled. Any ideas.

RE: Question: Configuring Multiple message-resources Elements W ith Sub-Applications
Well, I think I finally figured all this stuff out. It sure wasn't clear from any of the documentation I looked at. I'm not slamming the documenters out there b/c I know how it is. I just thought somewhere I'd find a clear explanation on this. I think the sub-application feature is one of the best things about Struts 1.1: Here's what you need to know: 1) Whatever key name you specify for a message-resource in a sub-app config file (e.g. SUB_APP_A_MESSAGES_KEY in my example below) gets a / plus the module name concantenated to it. So in my example, the message resource object (properties) gets stored in application scope under the key name SUB_APP_A_MESSAGES_KEY/sub-app-a. 2) In your JSP file, if you want to use the html:errors tag and the error messages are in a sub-app's message resource file, you'll need to specify the resource bundle. For example: html:errors bundle=SUB_APP_A_MESSAGES_KEY/sub-app-a / Be sure to include the errors.header, errors.footer, errors.prefix, and errors.suffix key/value pairs each sub-app's message resource file if you're using the html:errors tag. This was one thing I don't like about this approach. These header keys are duplicated across files -- if you're placing error messages for each sub-app in the corresponding message resource file. Unless I'm missing something, I think these header keys must be in the same file as the error message. 3) To write text in a JSP from a sub-app's message resource file, be sure to include the sub-app bundle: bean:message key=copyright.notice bundle=SUB_APP_A_MESSAGES_KEY/sub-app-a/ Note: - Now that I understand the naming convention for the keys to store/retrieve message resources by sub-app, I thought my convention was redundant. Therefore I changed the key name in ALL my sub-app config files to just be MESSAGE. For example: message-resources key=MESSAGE parameter=com.abc.training.LoginMessages null=false/ This will result in key names as follows: MESSAGE/sub-app-a MESSAGE/sub-app-b MESSAGE/sub-app-c ... Whew! I finally got this working!!

I searched the mailing lists, Struts documentation, and the online chapter's in Chuck Cavaness' upcoming Struts book (O'Reilly). I have not found a clear example on how to do this. Example #1 - Declaring All Message Resources In struts-config.xml: = --- struts-config.xml- struts-config message-resources parameter=com.abc.training.Messages null=false/ message-resources key=SUB_APP_A_MESSAGES_KEY parameter=com.abc.training.SubAppAMessages null=false/ /struts-config --- struts-config-sub-app-a.xml- struts-config form-beans ... /form-beans action-mappings ... /action-mappings /struts-config Example #2 - Declaring Each Message Resource In Each Sub App's struts-config-xml: --- struts-config.xml- struts-config message-resources parameter=com.abc.training.Messages null=false/ /struts-config --- struts-config-sub-app-a.xml- struts-config form-beans ... /form-beans action-mappings ... /action-mappings message-resources key=SUB_APP_A_MESSAGES_KEY parameter=com.abc.training.SubAppAMessages null=false/ /struts-config I can't get either approach to work. If I use approach #1, error keys are not properly located for errors placed in the errors container by sub-application A. Hence, error mesages appear as ???en_US.key???. But this approach does work for JSP text retrieved from sub-app A's message resource file (as long as I specify the bundle attribute). If I use approach #2, I get the following exception (WebLogic 6.1 with SP2 or SP3): javax.servlet.ServletException:
