RE: Data Validation
In our case, we have chosen to use the java.text.Format as a superclass of all our validation and formatting classes. I would suggest Struts to consider this approach. Our decision derives from the following requirements: 1 Validation of Strings data according to a specified format The basic requirement is to validate that a string complies to a specified format. For example, for a string representing a date, the requirement is to make sure it is of the form: dd/mm/. 2 Parsing Strings to Objects and vice-versa Beyond the simple aspect of validating the format of an input string, it is also often required to transform the validated string into a usable form for further processing. In Java this means creating an object instance from the string. With the date example, this could mean creating a java.util.Date object. On the other hand, it is also required to perform the reverse operation. In the case of an instance of a java.util.Date, it should be possible to get a string representation of it according to a specified format. 3 String buffer parsing and formatting It should be easy to parse only a certain part of a larger string when the latter contains the formatting of several elements. Conversely, it should be easy to append the string representation of an object to an existing string. This can be useful for example in the context of marshalling object instances into an XML representation. 4 Independence of the usage context The classes involved should be coupled to any context of usage. This is to allow maximum reuse of the logic in various contexts. For example the framework should not depend on the HTTP request of the Servlet API. This should enable the creation of a library of formatter that can be used in various projects. This library can contain basic formatters, but also more business oriented ones such as account number formatting, etc. 5 Internationalization In some cases it is necessary to have the parsing and validation processing aware of locale-specific factors. The date example is again a very good illustration of this requirement, whereby in the United States dates are of the form mm/dd/, while in Europe dates are of the form dd/mm/. In the context of a graphical user interface, this is an important requirement. The java.text.Format class satisfies all the above requirements. It is a standard Java object, so using it should be consistent with future Java developments. Finally, J2SE already proposes some formatters for numeric values, date, and messages. In our context, these format classes will be used for: - HTTP request parameter validation - Handling of request and return buffer to and from legacy systems - Displaying of the data elements in an HTML front-end Eventually, beyond the use of Format classes, we intend to create a sort of format class instance pool, whereby pre-initialized format classes are stored for repetitive usage. This avoids the creation and initialization of an object each time a validation/formatting has to be performed. The Struts digester would be a great tool for initializing this pool.

Cancel an upload form (Problem not solved yet)
Hi, I didn't find a solution to the problem described below (forwarded message). Currently the form and all its new data is stored, even if the user canceled. If the ActionServlet reads the cancel-Parameter from a multipart request, the action would be able to cancel the storing process. But the file will be uploaded though. If I don't use the Struts cancel mechanism where should I delete the data bean from the session?

These forms must include enctype="multipart/form-data" in their form-tag. The problem is that these multipart streams could be read just once.

RE: Data Validation
In our case, we have chosen to use the java.text.Format as a superclass of all our validation and formatting classes. Can you provide working examples of any of the classes you are using now? Putting something like this into a sample Struts application can really help move things along. Beyond the simple aspect of validating the format of an input string, it is also often required to transform the validated string into a usable form for further processing. Eventually, beyond the use of Format classes, we intend to create a sort of format class instance pool, whereby pre-initialized format classes are stored for repetitive usage. This avoids the creation and initialization of an object each time a validation/formatting has to be performed. The Struts digester would be a great tool for initializing this pool. A big example of that is inserting the value into a JDBC DBMS. Here, it can be convenient to use a string-based entity bean to work with the Struts form, and then let the driver do the final conversion of the validated sttring. A pool of JDBC-orientated validation classes sounds be very useful. If you haven't already, you should consider subscribing to the Struts-Dev too, where there is more talk about how to extend Struts. Could you provide a simple example of how you use the java.text.Format class to validate some standard types. For example, a form with fields like: Date Name Amount Telephone Number An important reason for validation, as you point out, is for later use of the value, especially the insertion of the value into the database. *** REPLY SEPARATOR *** On 2/6/2001 at 8:12 AM Rey Francois wrote: In our case, we have chosen to use the java.text.Format as a superclass of all our validation and formatting classes.

Struts and XHTML
Hi all, I'm a newbie to STRUTS, so please forgive my ignorance! 1. Does STRUTS support XHTML? Struts tags seem to generate uppercase tag names, which is invalid XHTML... 2. When STRUTS generates an input element, the unique identifier for the field is placed in the name attribute (deprecated since HTML 4.0 or even earlier) and not the id attribute. 3. Does STRUTS-generated HTML in general honor well-formed XML restrictions (eg closing end tags, quoting attribute values, etc)? Finally, where is the STRUTS FAQ page? Regards, Agnes Clarke

AW: JBuilder Enterprise

Februar 2001 17:32 An: [EMAIL PROTECTED] Betreff: Re: JBuilder Enterprise Did you figure out how to debug JSP's in the Enterprise Version? thats what I'm currently working on as I expected a much better performance from that... The first problem I still working on, however, is that it seems to be impossible to tell the Tomcat that comes with JBE which directory to use for configuration info. It always uses the root of the C: drive. As it appears to me right now, I'm no longer sure whether the Enterprise edition is worth the investment as the better debugging support would have been my main point in buying it.

RE: Data Validation
I posted this to struts-dev, but not to struts-user. I have a basic validation framework using regular expressions and I made an example struts application. The validation rules are stored in the validation.xml file. Having a java.text.Format class is nicer since it is locale based and also converts a string to another object. When I've had to convert a string to an another object, I've used regular expressions to get the pieces of the string that I want and then convert them to a date, for example. http://home.earthlink.net/~dwinterfeldt/ David Winterfeldt --- Ted Husted [EMAIL PROTECTED] wrote: In our case, we have chosen to use the java.text.Format as a superclass of all our validation and formatting classes. Can you provide working examples of any of the classes you are using now? Putting something like this into a sample Struts application can really help move things along. Beyond the simple aspect of validating the format of an input string, it is also often required to transform the validated string into a usable form for further processing. Eventually, beyond the use of Format classes, we intend to create a sort of format class instance pool, whereby pre-initialized format classes are stored for repetitive usage. This avoids the creation and initialization of an object each time a validation/formatting has to be performed. The Struts digester would be a great tool for initializing this pool. A big example of that is inserting the value into a JDBC DBMS. Here, it can be convenient to use a string-based entity bean to work with the Struts form, and then let the driver do the final conversion of the validated sttring. A pool of JDBC-orientated validation classes sounds be very useful. If you haven't already, you should consider subscribing to the Struts-Dev too, where there is more talk about how to extend Struts. Could you provide a simple example of how you use the java.text.Format class to validate some standard types. For example, a form with fields like: Date Name Amount Telephone Number An important reason for validation, as you point out, is for later use of the value, especially the insertion of the value into the database. *** REPLY SEPARATOR *** On 2/6/2001 at 8:12 AM Rey Francois wrote: In our case, we have chosen to use the java.text.Format as a superclass of all our validation and formatting classes. I would suggest Struts to consider this approach. Our decision derives from the following requirements: 1 Validation of Strings data according to a specified format The basic requirement is to validate that a string complies to a specified format. For example, for a string representing a date, the requirement is to make sure it is of the form: dd/mm/. 2 Parsing Strings to Objects and vice-versa Beyond the simple aspect of validating the format of an input string, it is also often required to transform the validated string into a usable form for further processing. In Java this means creating an object instance from the string. With the date example, this could mean creating a java.util.Date object. On the other hand, it is also required to perform the reverse operation. In the case of an instance of a java.util.Date, it should be possible to get a string representation of it according to a specified format. 3 String buffer parsing and formatting It should be easy to parse only a certain part of a larger string when the latter contains the formatting of several elements. Conversely, it should be easy to append the string representation of an object to an existing string. This can be useful for example in the context of marshalling object instances into an XML representation. 4 Independence of the usage context The classes involved should be coupled to any context of usage. This is to allow maximum reuse of the logic in various contexts. For example the framework should not depend on the HTTP request of the Servlet API. This should enable the creation of a library of formatter that can be used in various projects. This library can contain basic formatters, but also more business oriented ones such as account number formatting, etc. 5 Internationalization In some cases it is necessary to have the parsing and validation processing aware of locale-specific factors. The date example is again a very good illustration of this requirement, whereby in the United States dates are of the form mm/dd/, while in Europe dates are of the form dd/mm/. In the context of a graphical user interface, this is an important requirement. The java.text.Format class satisfies all the above requirements. It is a standard Java object, so using it should be consistent with future Java developments. Finally, J2SE already proposes some formatters for numeric values, date,

Re: Hacking Servlet Mill
Julia Reynolds wrote: Well, Craig was right and our problems with Struts and Servlet Mill apparently stem from the fact that it is Servlet 2.1, not Servlet 2.2 compatible. Can we just replace the servlet.jar file in Servlet Mill with the 2.2 servlet.jar? Is that safe, or will it break Servlet Mill? Unfortunately, that approach is unlikely to work. It's not just an issue of having the right servlet API classes (which are mostly interfaces). The servlet container has to support all of the required functionality -- most importantly, it needs to understand what a web application archive (WAR) file is, which 2.1 based containers don't.

Re: Struts and XHTML
"Clarke, Agnes" wrote: Hi all, I'm a newbie to STRUTS, so please forgive my ignorance! 1. Does STRUTS support XHTML? Struts tags seem to generate uppercase tag names, which is invalid XHTML... XHTML is not supported directly, but the "html" tag library strives to render code that is compatible with most XHTML requirements. Which tags in particular are you finding generate upper case tag names? There were some tags in 0.5 that produced mixed case attributes, but AFAIK all the tags rendered with current 1.0 code are pure lower case. 2. When STRUTS generates an input element, the unique identifier for the field is placed in the name attribute (deprecated since HTML 4.0 or even earlier) and not the id attribute. I missed catching that one -- let me look into it further. 3. Does STRUTS-generated HTML in general honor well-formed XML restrictions (eg closing end tags, quoting attribute values, etc)? Yes, to the maximum degree feasible. It renders closing tags for all the "open" tags that have nested content (like form and html), but does not render XML-style no content tags (br/) with the trailing slash included. All attribute values are quoted. Of course, Struts has no control over the non-Struts tags -- it is still up to the page designer to create valid syntax of the entire page. Finally, where is the STRUTS FAQ page? There is not really a FAQ page per se -- the best source of information is searching the STRUTS-USER mailing list archives. Regards, Agnes Clarke Craig

RE: No match was found for method setFilter(java.lang.String)
It's a JRun bug. I sent mail to this group on 31-JAN about it not being
fixed in SP2. Others have mentioned it as well. Allaire is silent on when
it will be fixed.
Cheers

Getting a value in the JSP from an ActionForm
Here's my dilemma (see 2 summary questions at end): I'm coming to a page with a value set in an ActionForm by my action for me. Works great. Now what I want to do is get that property out of that bean, and into another bean that's only being used on the page. Something conceptually like: jsp:useBean id="page_only_bean" scope="page" class="xyz" jsp:setProperty name="page_only_bean" value="action_form_bean.property" No go. Any thoughts on an easy way to do this? Alternatively I thought html:form looked up the bean, and put it under the name that i have registered in struts-config.xml for form-bean. So after my html:form tag, I tried: jsp:useBean id="page_only_bean" scope="page" class="xyz"/ % page_only_bean.setXXX(bean_name_from_form-bean_tag.getXXX()); % Again, no dice. JSP compiler says no such variable. Anyway, I guess this boils down to 2 simple questions: 1) (The most importnant) I've got an ActionForm that is populated and passed all around. I can directly manipulate it in Action classes no problem. html:text and bean:writes work fine. Now how do I get a real reference to the ActionForm in the JSP? (Why? What if I want to call getXXX() or setXXX() on the Form bean in a scriptlet?) 2) Is there a way using bean:define to copy a property from one bean into another bean? (Don't think so, although I can make a bean that consists just of that property...) Thanks, --tom

A more Struts-oriented solution might be some extended version of jsp:setProperty that behaves more like what you are trying ... maybe for Struts 1.1? No go. Any thoughts on an easy way to do this? Alternatively I thought html:form looked up the bean, and put it under the name that i have registered in struts-config.xml for form-bean.

What if I want to call getXXX() or setXXX() on the Form bean in a scriptlet?) The form bean for the current form is stored as a request or session attribute (depending on your struts-config.xml setting) with a key equal to the form name. That is how the html:form tag itself finds these beans, so you can count on it as well. 2) Is there a way using bean:define to copy a property from one bean into another bean? (Don't think so, although I can make a bean that consists just of that property...) Not yet, but a runtime expression should work as illustrated above. Thanks, --tom Craig

Locale differences between Windows Linux JDK?
I'm seeing a confusing difference in the localized message resource behavior between the same application running on Windows 2000 and on Linux. My error messages in the resources file are all non-localized, and thus not prefixed, but simply named (ie "errors.header"). On a Linux server, messages like errors.header are correctly looked up and retrieved. With the same application on a Windows 2000, the resource is not found, and instead I see ???en_US.errors.header??? (with IE 5.5) or ???en.errors.header??? (with netscape 4.7). I thought that perhaps disabling locales using the ActionServlet init parameter "locale"=false would solve it, but it had no effect. Obviously, I would prefer not to have to duplicate my messages with the appropriate prefix, and instead for struts to fall back to the default unprefixed message if a localized one is not found. I know I'm missing something simple; localization is totally new to me. The only obvious thing I thought to check was Locale.getDefault(), which returns en_US on both sides. I hate to ask for a localization (or, really, delocalization :) primer here, but... um... any suggestions? It's the same app code on both sides; I'm using Struts from cvs, and Sun JDK 1.3 on Red Hat 6.2 with Apache 1.3/Resin 1.2.2, and Windows 2000 with just Resin 1.2.2. Andy Boyko [EMAIL PROTECTED]
RE: Locale differences between Windows Linux JDK? NEVERMIND; SORRY
I'm seeing a confusing difference in the localized message resource behavior between the same application running on Windows 2000 and on Linux. Oh, jeez. I'm embarrassedly, sheepishly sorry - as usual, when things seem fundamentally broken, check the obvious stuff first. The only problem here was with my build process, which wasn't copying the message resource file from my source tree into my webapp dir. Cross-platform development always sounds like a better idea than it is. Andy Boyko[EMAIL PROTECTED]
