DynaValidatorForm for java.lang.Integer
Hi all, I have a problem using Validator with DynaBeans. In my struts-config if I declare java.lang.String props for a DynaValidatorForm a "required" validation works fine, but if I change the props to java.lang.Integer the "required" validation fails ( no ActionErrors returned ). Please hep me! I'm using struts 1.1, validator 1.0.2, commons-beanutils 1.6.1 ( maybe this is the problem? ) on tomcat 5.1.19. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: DynaValidatorForm for java.lang.Integer
Use String. Anything else is asking of trouble. According to the party line (ref: struts dev list) action form properties should always be of type string. You can still validate whether a string is "1" for example or whether it looks like a date whatever, it doesn't have to be typed as such.

JSPG0103E: Unable to open taglibrary /WEB-INF/struts-bean.tld
Hi All, In our project we are getting an error with the subject as the error message. We are getting this in the development environment. We are using WSAD 4.0. The interesting thing is we are not getting the error when we are using WAS 4.0.1 as part of WSAD but with WAS 4.0.2. I'm writing the error message again below. Have tried searching on struts, google and almost every other option but failed to find a solution to this... Has anyone else faced this? Is there a solution to this? thanks ansu [3/17/04 11:25:41:734 CST] 70060345 OSEListenerDi X PLGN0021E: Servlet Request Processor Exception: Virtual Host/WebGroup Not Found : The web group / has not been defined java.lang.ClassCastException: org.apache.xerces.jaxp.DocumentBuilderFactoryImpl at javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:147) at org.apache.jasper.compiler.JspUtil.parseXMLDoc(JspUtil.java:187) at org.apache.jasper.compiler.TagLibraryInfoImpl.parseTLD(TagLibraryInfoImpl.java:473) at org.apache.jasper.compiler.TagLibraryInfoImpl.(TagLibraryInfoImpl.java:305) at org.apache.jasper.compiler.JspParseEventListener.handleDirective(JspParseEventListener.java:800) at org.apache.jasper.compiler.DelegatingListener.handleDirective(DelegatingListener.java:116) at org.apache.jasper.compiler.Parser$Directive.accept(Parser.java:216) at org.apache.jasper.compiler.Parser.parse(Parser.java:1115) at org.apache.jasper.compiler.Parser.parse(Parser.java:1066) at org.apache.jasper.compiler.Parser.parse(Parser.java:1062) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:237) at org.apache.jasper.runtime.JspServlet.loadJSP(JspServlet.java:697) at org.apache.jasper.runtime.JspServlet$JspServletWrapper.loadIfNecessary(JspServlet.java:244) at org.apache.jasper.runtime.JspServlet$JspServletWrapper.service(JspServlet.java:261) at org.apache.jasper.runtime.JspServlet.serviceJspFile(JspServlet.java:430) at org.apache.jasper.runtime.JspServlet.service(JspServlet.java:565) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at com.ibm.servlet.engine.webapp.StrictServletInstance.doService(ServletManager.java:827) at com.ibm.servlet.engine.webapp.StrictLifecycleServlet._service(StrictLifecycleServlet.java:167) at com.ibm.servlet.engine.webapp.IdleServletState.service(StrictLifecycleServlet.java:297) at com.ibm.servlet.engine.webapp.StrictLifecycleServlet.service(StrictLifecycleServlet.java:110) at com.ibm.servlet.engine.webapp.ServletInstance.service(ServletManager.java:472) at com.ibm.servlet.engine.webapp.ValidServletReferenceState.dispatch(ServletManager.java:1012) at com.ibm.servlet.engine.webapp.ServletInstanceReference.dispatch(ServletManager.java:913) at com.ibm.servlet.engine.webapp.WebAppRequestDispatcher.handleWebAppDispatch(WebAppRequestDispatcher.java:523) at com.ibm.servlet.engine.webapp.WebAppRequestDispatcher.dispatch(WebAppRequestDispatcher.java:282) at com.ibm.servlet.engine.webapp.WebAppRequestDispatcher.forward(WebAppRequestDispatcher.java:112) at com.ibm.servlet.engine.webapp.SimpleFileServlet.doGet(SimpleFileServlet.java:223) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at com.ibm.servlet.engine.webapp.StrictServletInstance.doService(ServletManager.java:827) at com.ibm.servlet.engine.webapp.StrictLifecycleServlet._service(StrictLifecycleServlet.java:167) at com.ibm.servlet.engine.webapp.IdleServletState.service(StrictLifecycleServlet.java:297) at com.ibm.servlet.engine.webapp.StrictLifecycleServlet.service(StrictLifecycleServlet.java:110) at com.ibm.servlet.engine.webapp.ServletInstance.service(ServletManager.java:472) at com.ibm.servlet.engine.webapp.ValidServletReferenceState.dispatch(ServletManager.java:1012) at com.ibm.servlet.engine.webapp.ServletInstanceReference.dispatch(ServletManager.java:913) at com.ibm.servlet.engine.webapp.WebAppRequestDispatcher.handleWebAppDispatch(WebAppRequestDispatcher.java:523) at com.ibm.servlet.engine.webapp.WebAppRequestDispatcher.dispatch(WebAppRequestDispatcher.java:282) at com.ibm.servlet.engine.webapp.WebAppRequestDispatcher.forward(WebAppRequestDispatcher.java:112) at com.ibm.servlet.engine.srt.WebAppInvoker.doForward(WebAppInvoker.java:91) at com.ibm.servlet.engine.srt.WebAppInvoker.handleInvocationHook(WebAppInvoker.java:184) at com.ibm.servlet.engine.invocation.CachedInvocation.handleInvocation(CachedInvocation.java:67) at com.ibm.servlet.engine.srp.ServletRequestProcessor.dispatchByURI(ServletRequestProcessor.java:122) at com.ibm.servlet.engine.oselistener.OSEListenerDispat
portal concepts [was: what would it take to build site navigation into struts?]
After taking a BroadVision One-To-One Portal Developer Workshop this week and seeing how BroadVision uses Struts, I have come to realize that some of the functionality that their product provides could be built directly into Struts itself. Let's start with a simple site map: 0. Root 1. Home 1. Products 1. Product Line 1 1. Product A 2. Product B 3. Product C 2. Product Line 2 1. Product D 2. Product E 2. Personal Home Page 1. Personal Weather Portlet 2. Personal Stock Portlet First, BroadVision Portal provides an admin tool and an API to build page hierarchies like what is shown above. Every page within the page hierarchy knows itself, its parent, its siblings, and its children. Having an API like this prevents a page from ever becoming an orphan. It also allows sitemaps to be dynamically created and for each page to know how to build its own breadcrumb navigation like this: Home >> Products >> Product Line 1 >> Product B Second, each of the above pages can contain zero or more pieces of "content". Broadvision is designed so that multiple pages can point to the same "content". This is the same way multiple Struts Actions can point to the same JSP. Third, they provide a way to create a user profile. Fourth, BroadVision provides a way to define what they refer to as qualifiers. For instance: Department: IT, HR, Finance, Marketing, Sales, etc. User Type: Customer, Employee, Supplier, Distributor Role: Admin, Power User, User, Guest Language: English, French, German These qualifiers can be assigned to each page within the page hierarchy, each page's content items, and each user profile. This allows the portal to dynamically determine what content to display to a user based on what qualifiers have been assigned to the user. If no qualifiers have been assigned to a page, the page is publicly visible. Otherwise, unless the user profile has the same qualifiers assigned to it as the page, the page will not be visible. The same rules apply to the content items on the page. The cool part about this is that the user only sees the content relevant to them. Thus you are able to create truly dynamic content. There are, of course, a lot more features associated with BroadVision Portal than what I have listed above. I am mainly looking to have some type of Page Hierarchy concept built into Struts as a Plugin as tightly as Tiles is. The rest of the features could be added onto that concept over time. What do others think? Andy -Original Message- From: Adam Hardy [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 17, 2004 3:52 AM To: Struts Users Mailing List Subject: Re: what would it take to build site navigation into struts? You're talking about breadcrumbs as site navigation - just to be clear, because there is another implementation of breadcrumbs as history navigation. It is relatively simple to implement (and maintain) a navigation breadcrumb menu using Tiles, which shows the position of your page in the heirarchy. It is basic, so I'm not sure if it could fulfil what you describe as 'knowing its relationship to the rest of the pages' or an 'API to know the current page's parent siblings & children'. Perhaps a couple of examples to show what you mean would help. Adam On 03/17/2004 04:45 AM Andrew Freeman wrote: > I have been learning about a web portal tool called BroadVision Portal.

File-Upload: Progress-Bar
Hello everybody! I'm up to the task to implement a progress bar for File-Uploads, cause the files that are uploaded to my Webapp can be quite large. Well as usual this problem is not easily solved on the HTTP-Browser upload side. I'm using Struts here so I'm also using the commons/FileUpload. I was planning to do it that way that I assign a unique number to every session's-upload and keep the current status of an upload in a singleton for access. In an additional frame (with refresh) I would like to show the progress bar. My question: Has anybody done something like this with Struts before and can give me some little advise? Or more specific: Is it possible to first get the complete filesize from the FormFiles and the do the real Upload during the Action (keeping track of the read bytes) Thx for every help!! ___ Tim Adler, Abt.

trapping.

AW: SessionTimeout handling
I do something similar. I don't know which version of Struts you are using,
but I decided to create a general SessionTimeoutException and forward the
User to a SessionTimeout page when that error occurs. I'm simply configured
a GeneralFoward for the SessionTimeout page.
protected void ensureSessionSecurity(HttpServletRequest request)
throws AzDiasMinerSessionTimeoutException
{
HttpSession session = request.getSession(false);
if(session == null || session.isNew())
{
session.invalidate();
throw new AzDiasMinerSessionTimeoutException();
}
}
On the respective page the User can read about the Timeout. You just need to
catch and forward on this exception.
}
catch(AzDiasMinerSessionTimeoutException ase)
{
return mapping.findForward("session_timeout");
}
I also did that in a subclass of Action.
PLEASE NOTE: You have to check for isNew() cause Tomcat e.g. creates a new
session even if your call getSession() with false. The Specs say that null
should normally be returned instead.

RE: RE: Re: Performance Improvement :: Struts based applications
Raise the debug level for certain packages in your production environment (if you run debug there at all), set classes like log4j.logger.org.apache.commons.digester to FATAL. This will trim down your log files considerably. You should consider proper use of the logging levels within your application to provide meaningful INFO/ERROR messages so you should not have to run at DEBUG level anywhere other than in development. - How soon after starting up your appserver are you trying to hit your application ? You have to allow time for the appserver to initialise its resources. Tomcat 4.1.24 takes a little over 6 seconds to boot on one of our development boxes and initialise 7 (pre-deployed) applications, and be ready to service requests. If you are starting your appserver and having it redeploy your war file on startup then you should be expected to wait for it to initialise. If you setup connection pools on startup then check they are all available and none are timing out etc. As another user said you could always run JProbe to get to the root cause without too much hassle :) Chris McCormack -Original Message- From: Scott Piker [mailto:[EMAIL PROTECTED] Sent: 18 March 2004 22:23 To: [EMAIL PROTECTED] Subject: Re: RE: Re: Performance Improvement :: Struts based applications What's your logging level set to?

RE: Database backed forms
I guess your first place to look would be DynaActionForm - this base class dynamically creates FormAction objects setting the properties from the struts-config file. http://jakarta.apache.org/struts/api/org/apache/struts/action/DynaAction Form.html DynaValidatorActionForm adds validator support to this. Perhaps you could extend this class to add your own methods for specifying form properties on the fly. The key function seems to be initialize(FormBeanConfig) - FormBeanConfig "represents the configuration information of a element in a Struts configuration file". So create a FormBeanConfig object in code to represent the dynamic data you want and then initialize a DynaActionForm with this object. Add properties to FormBeanConfig with addFormPropertyConfig. That sounds like a realistic starting point... Anyone else have any ideas suggestions or corrections? -Original Message- From: Melonie Brown [mailto:[EMAIL PROTECTED] Sent: 18 March 2004 18:30 To: [EMAIL PROTECTED] Subject: Database backed forms I have written a very rough website page content management system using Struts and OJB.

Help with StrutsStudio
Has anyone used JNDI Naming for Excadel Struts Studio using
Tomcat Server 4.
following is the code (how it shud be) for JNDI Naming for an
EJB with JNDI Name VesselManager
Context ctx = new javax.naming.InitialContext();
Object ref = ctx.lookup("VesselManager");
VesselManagerHome vesselManagerHome = (VesselManagerHome)
PortableRemoteObject.narrow(ref, VesselManagerHome.class);
vesselManager = vesselManagerHome.create();
According to Tomcat Documentatin .. it should be like this ::
Context ctx = new javax.naming.InitialContext();Context
envCtx = (Context) ctx.lookup("java:comp/env");
Object ref2 = envCtx.lookup("VesselManager");
VesselManagerHome vesselManagerHome = (VesselManagerHome)
PortableRemoteObject.narrow(ref2, VesselManagerHome.class);
vesselManager = vesselManagerHome.create();
.. any help for using EJBs in StrutsStudio Or even just struts
would be highly appreciated.
Thanks in Advance... farrokh.

AW: SessionTimeout handling
Well I simply subclassed "Action" to my own and made the session-checking
configurable through properties for the respective ActionMapping. Therefore
you simply need to subclass ActionMapping also and put this on top of your

Properties will be read to the customer ActionMapping throgh reflection just
like in FormBeans.

RE: Database backed forms
I've seen many posts on "Not pre-populating action forms". This seems to be a design decision as action forms are only for validating input. However, in most applications I write I don't want to only input data but to view and edit existing data as well. For me ActionForms seem to be the best way to code an input/output layer between the browser and the backend. In order to view and edit existing data, the action form needs to pre-populate its data from the backend before displaying the form. How would you suggest implementing view/edit functionality without pre-populating action forms? I've coded pre-populating action forms in the following way: 1) I've got session objects to maintain my current system state (whether I'm looking at an extisting object or creating a new one) 2) I've extended DynaValidatorActionForm to provide a reset() implementation.

Re: File-Upload: Progress-Bar
A simpler solution that may still meet your needs might be to use an animated GIF on a pop-up just to give the user some feedback that the upload is still in progress and that they should be patient. You could setup something like this: The HTML form with upload file input element has a hidden field with some UUID generated by the Action. The UUID is just some unique ID to avoid having two upload forms with the same ID. For instance, the session-id or perhaps session-id+current_time would work fine for a UUID. Have the javascript onSubmit for the form pop-up a window, where the content of that window will be /uploadStatus.do?UUID=234344. Your /uploadStatus.do action will look for the UUID and forward to a JSP with the animated GIF in it if that file has not completed uploading. That JSP will have a meta-refresh in it that will refresh the content of the pop-up every few seconds. The form submit with the file upload input element will be uploading the file for a while. When it finishes, it will indicate that the file upload with UUID=234344 has completed to some server-side upload-tracking subsystem. Then it will forward or redirect to whatever page the user should see when the upload completes. The pop-up status window will refresh itself within a second or two, and the /uploadStatus.do action will determine that the upload for the file with UUID=234344 has completed (by checking with the server-side upload-tracking subsystem). It will then forward to a JSP that closes the pop-up window or shows a message that the upload has completed. This isn't a progress bar, but it should be easier to implement. You could even use a fast-cycling animated GIF that looks like a progress bar (but doesn't really relate to the actual % progress) if that would satisfy your UI design requirements. -Max - Original Message - From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, March 19, 2004 1:31 AM Subject: File-Upload: Progress-Bar Hello everybody!

Re: portal concepts [was: what would it take to build site navigation into struts?]
Are you aiming to put Broadvision out of business? ;) It sounds like quite a task. The admin tool that you use to build page heirarchies - how does it store the info? XML presumably? And the XML is read by the application at run-time. And so your plug-in would do the same - read its config from an XML file to establish the heirarchy and relationships. The dynamic part sounds like a major piece of work - but you wouldn't necessarily need that - or is it integral? I suppose it depends on how much static content you have. Obviously with lots of static content, then it would seem churlish not to allow dynamic rearrangement of the site map. But it depends on how you do it - most of the URLs in a struts-tiles app are based in files that can only be reloaded by reloading the whole app. I think that's your first worry. Adam On 03/19/2004 09:45 AM Andrew Freeman wrote: After taking a BroadVision One-To-One Portal Developer Workshop this week and seeing how BroadVision uses Struts, I have come to realize that some of the functionality that their product provides could be built directly into Struts itself. Let's start with a simple site map: 0. Root 1. Home 1. Products 1. Product Line 1 1. Product A 2. Product B 3. Product C 2. Product Line 2 1. Product D 2. Product E 2. Personal Home Page 1. Personal Weather Portlet 2. Personal Stock Portlet First, BroadVision Portal provides an admin tool and an API to build page hierarchies like what is shown above. Every page within the page hierarchy knows itself, its parent, its siblings, and its children. Having an API like this prevents a page from ever becoming an orphan. It also allows sitemaps to be dynamically created and for each page to know how to build its own breadcrumb navigation like this: Home >> Products >> Product Line 1 >> Product B Second, each of the above pages can contain zero or more pieces of "content". Broadvision is designed so that multiple pages can point to the same "content". This is the same way multiple Struts Actions can point to the same JSP. Third, they provide a way to create a user profile. Fourth, BroadVision provides a way to define what they refer to as qualifiers. For instance: Department: IT, HR, Finance, Marketing, Sales, etc. User Type: Customer, Employee, Supplier, Distributor Role: Admin, Power User, User, Guest Language: English, French, German These qualifiers can be assigned to each page within the page hierarchy, each page's content items, and each user profile. This allows the portal to dynamically determine what content to display to a user based on what qualifiers have been assigned to the user. If no qualifiers have been assigned to a page, the page is publicly visible. Otherwise, unless the user profile has the same qualifiers assigned to it as the page, the page will not be visible. The same rules apply to the content items on the page. The cool part about this is that the user only sees the content relevant to them. Thus you are able to create truly dynamic content. There are, of course, a lot more features associated with BroadVision Portal than what I have listed above. I am mainly looking to have some type of Page Hierarchy concept built into Struts as a Plugin as tightly as Tiles is. The rest of the features could be added onto that concept over time.

AW: File-Upload: Progress-Bar
Well that was generally what I was planning to do. The GIF-animation is somewhat a good idea, but if I do such an server-side upload system, then I could also do a real-percentage progress bar. I think a simple open-window-close-window could be done with JavaScript also. But anyway thanks for the suggestion. Now the tricky part is: How do I do this server-side upload-system? Perhaps you can help here also. I already implemented a singleton that keeps track of upload-numbers for every session. So that I always have a unique identifier combined out SessionId and Upload-Number. My problem is tracking down the current status of an upload. Meaning: When I upload files with Struts then the File is immediately available through the FormFiles. Now: Is it possible to handle this upload through the FileForm.getInputStream(). Or is the File already completely read, when I get access to that method in the Action?! And if that is so, do I have to parse the Multipart-Request by myself then?? -Ursprüngliche Nachricht- Von: Max Cooper [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 19.

Hmm..Your syntax looks right to me, though you are missing a closing > just

Could the problem lie elsewhere?
Can you write out the accounts.number/account.no_account label/value as a
simple list?

Dear,
I'm not an expert in Struts and Java. I need some simple help:
Everything works fine, but at ??? mark I would like take
account.no_account like ${accounts.number}, but it doesn't work. May someone
can give me a small note about the right syntax to get the value from
accounts.number as text in the quotes.
Thanks

You will need to use Struts-EL taglib then you should be able to do what you want.

If there are any restrictions in file upload, what should be the maximum file size that can be uploaded? Are there any other ways of using FormFile and uploading files as large as 800MB - 1GB? File-upload has a threshold after which it writes uploads to disk instead of holding them in memory, so in theory, there are no software limitations. You might run into server or network issues with uploads that large, but the risk of a webapp OutOfMemoryError is controlled by this threshold. These values are set in the controller-config; see the docs for struts-config.xml for details.

RE: File-Upload: Progress-Bar
I could tell you how I'm going it (I also have very large files to upload.) 1) Once the upload request comes in, I launch a thread from my action class/servlet to handle the actual upload 2) I then forward to a page which displays a message indicating status. 3) I use java script to submit the status page so I can check on the progress of the upload and prevent browser timeout. I set this submit for every 10 secs. 4) Once I determine that the upload has completed, I forward back to my upload jsp page (or wherever you need to go next.)

Can coarse grained ActionForms validate?
Hi, I am using coarse grained action forms that are re-used by various action classes. Each of these action classes serve a different page and retrieves information from the backend so that the jsp page can show it. Now because I am using coarse grained forms, I have now way of knowing which fields to validate because the same form serve multiple actions. Also, if I use the ActionForm class to validate the client data, the ActionForm has to be responsible for re-initializing that page with backend information if validation fails. Therefore, even if I change to very fine-grained DynaForms and use the validation framework so that each action maps to one form, I will probably have to figure some way of fetching backend information if validation fails. Currently, I am doing all the client input validation in the action classes because it seems to be the most simple solution; however, it has the caveat that the action class is now responsible for both validation and backend service delegation. I am just wondering if there is a more elegant solution using the action forms as the validator. Any help is greatly appreciated.
RE: Can coarse grained ActionForms validate?
Are you using the validator framework? If you are, you can associate different validation rules with different actions for the same form (use DynaValidatorActionForm).

Now because I am using coarse grained forms, I have now way of knowing which fields to validate because the same form serve multiple actions. Also, if I use the ActionForm class to validate the client data, the ActionForm has to be responsible for re-initializing that page with backend information if validation fails. Therefore, even if I change to very fine-grained DynaForms and use the validation framework so that each action maps to one form, I will probably have to figure some way of fetching backend information if validation fails. Currently, I am doing all the client input validation in the action classes because it seems to be the most simple solution; however, it has the caveat that the action class is now responsible for both validation and backend service delegation. I am just wondering if there is a more elegant solution using the action forms as the validator. Any help is greatly appreciated.

Re: Can coarse grained ActionForms validate?
Hi Jim, You can specify multiple form bean mappings per action form. For insance: Then, in your validation.xml, you can have different rules for both of those forms.

Pl. help options collection
Dear All Can any body complete this oode , I mean to say that what needs to be done in configuration file struts-config, where ARRAY information must be kept.. Can any body complete the code that it will be directly a working code .I have successfully completed select using simple options . But want to learn using collections I am suing struts1.1. I am trying from so many days ...pl. help Many many thanks in advance pl. help.. Kind Regards Strutsguy If nay boy needs all code for above I can send all with java class and config file . ARRAY information ArrayList prod = new ArrayList(); prod.add( new org.apache.struts.util.LabelValueBean( "Widget", "20" ) ); prod.add( new org.apache.struts.util.LabelValueBean( "Sprocket", "29-2a" ) ); prod.add( new org.apache.struts.util.LabelValueBean( "Cog", "29s" ) ); prod.add( new org.apache.struts.util.LabelValueBean( "Dunsel", "943" ) ); LabelValueBean takes the first String argument as the displayed name and the second as the value returned. Well see more about this in a bit. Now that you have prod set up, you pass that as a session or request bean to the JSP. request.setAttribute( Constants.PRODUCT_KEY, prod ); (the Constants.PRODUCT_KEY is set to our bean name: "products"; we use this to centralize bean name management) To use the data in the JSP, add the following code: Notes: product_id is the variable the JSP will set to the product ID value of the product selected by the user. products is the name of the bean (it must match what is in Contants.PRODUCT_KEY -- we probably could've said ... collection="<%= Constants.PRODUCT_KEY %>" ... in place of hard-coding the name. The choice is up to you. property="value" and labelProperty="label" are automatically set by org.apache.struts.util.LabelValueBean, so only use the values shown here. The resulting HTML will look something like: Widget Sprocket Cog Dunsel

RE: Can coarse grained ActionForms validate?
Thanks gentlemen. This solves the problem for different validation rules for the same form, but I still need to figure how to get information from the backend that the form doesn't store. For example each form has a section on user input, which will be populated with user info if validation fails. However, below that section is an area that holds readonly information that is retrieved from backend services, so I need to retrieve this again unless I store it in the session, which I hesitate to do. So even though I can specify which rules apply to the same form, I cannot specify which initialization code to use when validation fails. -Original Message- From: Blake Whitmore [mailto:[EMAIL PROTECTED] Sent: Friday, March 19, 2004 9:50 AM To: Struts Users Mailing List Subject: Re: Can coarse grained ActionForms validate?

Re: Object insertion semantics

What are the expected semantics for object insertion? I'm a bit confused
by what I'm seeing here :) Here's some sample code:

Database db = odmg.newDatabase();
db.open("repository.xml", Database.OPEN_READ_ONLY);
try {

txn.begin();
db.deletePersistent(p2);
txn.commit();
} catch (Throwable t) {
System.out.println("got a "+t.getClass().getName());
}
db.close();
}
Assume player1 exists and player3 doesn't. I'm getting several surprises
with this.
First, the insertion of player1 fails, as it should. But I expected it
to fail on the call to lock(). It doesn't fail until the commit() at
which point I get a org.apache.ojb.odmg.TransactionAbortedExceptionOJB.
Is this the expected behaviour?
Next, the insertion of player3. This succeeds. What I was expecting was
an error on the second call to lock(). I could see it failing in
commit() instead for consistency with what I saw on player1, but it
ought to fail somewhere shouldn't it?
Finally, the call to deletePersistent is having no effect. I'm unable to
delete objects after I insert them. Am I doing something wrong or is
this an OJB bug?
I suspect some or all of these problems may be to do with OJB's primary
key handling. I'm using database native sequences and OJB seems not to
cope with that correctly, going on the SQL statements P6Spy is reporting:
1079658237422|1|0|statement|SELECT password,email,name,ID FROM PLAYER
WHERE ID = ? |SELECT password,email,name,ID FROM PLAYER WHERE ID = ''
[from the first call to lock() on player3; the second call generates no
SQL]
1079658237473|2|0|statement|DELETE FROM PLAYER WHERE ID = ? |DELETE FROM
PLAYER WHERE ID = ''
[on the call to deletePersistent, which explains why it's not doing much]
ID is an anonymous property on Player; could that be a factor? Here's
the repository entry for the class:

Iterating through a Hashtable of Vectors
Hi all
I've created a Hashtable, who's values are Vectors:
Vector a = new Vector();
a.add("something");
a.add("somethingelse");
Vector b = new Vector();
b.add("something");
b.add("somethingelse");
Hashtable ht = new Hashtable();
ht.put ("key", a);
ht.put ("anotherkey", b);
request.setAttribute("attrkey", ht);
What I want to be able to do is iterate through this Hashtable (in the JSP),
pull out a Vector, and iterate through it. How would I do this?

RE: Progress-Bar & Task Delegate
I love that article! I've been looking into Quartz to manage some long-running tasks on my business tier, but couldn't find a good way to get status updates to the admin. With this example, I can merge their TaskBean with a Business Delegate, creating a 'Task Delegate'?

Re: Iterating through a Hashtable of Vectors
I'm going to add some more the my previous post, and put the whole thing
into an understandable context... please bear with me.
In addition to the Hashtable mentioned below, I have another Vector (let's
call this 'ACCVEC'). ACCVEC contains account numbers as Integer objects.
On my JSP page, I use to list these account numbers on the
screen.
The keys in the aforementioned Hashtable are also account numbers (as
Integers). The corresponding value is a Vector (let's call this 'INVVEC')
of invoice numbers that are related to the account. It should be noted that
not every account number in ACCVEC is not a key in the Hashtable. That is,
there may be some accounts that have no invoices.
What I'd like to do is create a table (in my JSP) with a list of all account
numbers (as in ACCVEC), and an associated of invoice numbers,
if they exist.
Essentially, what I want is:
for each account number in ACCVEC {
display the account number
attempt to retrieve a value from the Hashtable for this account number
if there is a INVVEC {
for each invoice number in INNVEC {
create a select drop down box
}
}
}
How should this look using Struts?

Mapping Forward to new form
Hey,
I am adding user details to the DB through a form, on a successful insert I
would like to map forward to the same form.
The problem is when I use the action forward the form on the forwarded page
is filled with the details from the user I just added.
if(addUser((UserForm) form, request, response))
{
return (mapping.findForward("adduser"));
}
I would like to map to a new blank form, how do I do this?
Thanks

Giving you something like test ((ignoreDate == "yes") or ( #insert date validation# )) or should I just write my own validation rule / do it with javascript before I submit?

Re: UTF-8 characters in the name of the uploaded document
Hi Zsolt,
I wrote this reply in response to the same problem but in a different
thread. I couldn't find it in the struts mailing list archives, so I
include it again with the message it responds to. Someone has since
written to me confirming that this does work.

Yes, I think you are right, i didn't realise which class we were talking
about there. I have just read a bit more about the Struts FileUpload
and how it wraps commons upload. Assuming Commons Upload works
correctly with the setHeaderEncoding, then I guess there might be work
around.
Struts will use org.apache.struts.upload.CommonsMultipartRequestHandler
by default to handle extracting the parameters out of the request and
populating the form. It uses the DiskFileUpload class from Commons
FileUpload. It is that handler that we need to modify, to do that we
could create our own using the
org.apache.struts.upload.CommonsMultipartRequestHandler source as the basis.
We need to tell Struts to use ours instead of the defualt by adding this
to your struts-config.xml
Then to modify org.apache.struts.upload.CommonsMultipartRequestHandler
by creating our my.own.MultiPartClassHandler class.
We need to modify the handleRequest() method like so:
// Create and configure a DIskFileUpload instance.
DiskFileUpload upload = new DiskFileUpload();
upload.setHeaderEncoding("UTF-8");
// Set the maximum size before a FileUploadException will be thrown.
upload.setSizeMax((int) getSizeMax(ac));
...
This is all untested and off the top of my head, so there is likely to
be a mistake there somewhere, but I think it is possible.

I see a similar problem with file upload. It doesn't look like
org.apache.strugs.upload.FormFile exposes a setHeaderEncoding method...

I have not used the file upload yet, but I believe you need to set the
encoding for the headers
formFile.setHeaderEncoding("UTF-8")
setHeaderEncoding does this:
"Specifies the character encoding to be used when reading the headers of
individual parts. When not specified, or |null|, the platform default
encoding is used."
If this was running on a English operating system it is probably
defaulting to the Latin-1 encoding.
From this Java Doc:
http://jakarta.apache.org/commons/fileupload/apidocs/org/apache/commons/file
upload/FileUploadBase.html#setHeaderEncoding(java.lang.String)
Please post back to the forum if this works. I would be interested in
the result.

Hi,
my application has to support UTF-8 including when files are uploaded
with UTF-8 characters in the filename (for example:
??.txt).
I use a servlet filter that always call
request.setCharacterEncoding("UTF-8") and my jsp pages contain
response.setContentType("text/html; charset=UTF-8");
Everything works fine except that I have problems with decoding of the
name of uploaded filenames.
I use the code below to get the name of the uploaded filename:
String nm = formFile.getFileName();
String filename = new String(nm.getBytes(), "UTF-8");
The code above converts only the first couple of characters correctly
(result: ??.txt).
Any ideas how to fix the problem?
I use TC-4.1.29, Struts-1.1, jdk1.4.2_02 Windows-XP.

In this article:

The author mentions that a filter is required for UTF-8 encoded forms.
Worth a go?

Hi,
I use struts-1.1 with tomcat-4.1.30 and cannot get the name of
the uploaded
document correctly if that contains UTF-8 (Asian) characters. The
application itself does work fine with UTF-8 characters in forms etc. the
only exception is upload. Is there a fix to solve this problem or
will it be
fixed in the next release?
