SV: Tiles:displaying document with tiles

Re: caching large data in web application
Well, if the data is read only, then you can just cache the data in a Hashtable and make it accessible through out the application. If your data is volatile, then you may consider writing a simple time based caching service - http://www.javaworld.com/javaworld/jw-07-2001/jw-0720-cache_p.html Hibernate provides two levels of caching. By default, Hibernates uses first level caching. Hibernate also provides plugin for other cache provider like JBoss. This is the second level caching. In first level caching, Hibernate will check if data in a persistence class has changed when saving a persistence class. If the related data is being modified, Hibernate will update the modified data. Of course, this is just one simple example. For more information, please visit Hibernate reference document - http://www.hibernate.org/hib_docs/reference/en/html/ HTH Lee On Mon, 29 Nov 2004 07:36:43 -0800 (PST), Ashish Kulkarni <[EMAIL PROTECTED]> wrote: > Hi > The data which i want to cache has about 1 rows > and i want to cache it in may be servlet context, what > is the best way to cache it, do i just create a java > bean and cache it or some kind of mechanism already > exist like Hibernation (i am not sure what is does) > > Ashish > > > --- "Frank W.

Re: RE: MVC initialization
Thank you both much!!! I guess I will try using the ServletContextListener because I am using Servlet 2.3 as found in Tomcat 4.1. I have tried hard on staying away from having a common initilization, but the scope of the service platform I created requires the ability now...so that each product can have its own specific interface callbacks as need be. Guess this is the only way to achieve a generic platform and have specific service interfaces that sit on top. Thank you for the help.

Re: nested tiles
Yeah, I also wish there was more documentation on this. I think I found the flaw in your original design. In layout.jsp you want to take the "body" attribute defined in tiles-def.xml and pass it on to bodyFrame.jsp as "bodypage". So you need to use beanName, right? tiles-def.xml: --- layout.jsp -- bodyFrame.jsp Does that work for you? Stefan Clos wrote: thanks Bill, your way to make nested tiles works fine. (After i changed "extends" to "template" in the second definition). It has the advantage that the jsp´s are smaller and easier to understand, but at the cost you need 2 definitions for each page. If you are only use one BodyFrame, you need a little more code i think. I hope there are coming a better documentation about nested tiles with some best practics in future. Stefan Bill Keese schrieb: Interesting. I'm not sure why your code doesn't work. Maybe the value attribute in should be /WEB-INF/pgs/startpage.jsp.

Re: Struts training
You will be introduced to Struts, the primary MVC framework for building Java Web Applications. Doesn't sound like they go into it very deeply. It may be a very good class for a person that hasn't done any web development using Java technologies though. You should have approximately three months Java experience. No web development or XML experience is necessary, but would be useful. A person really needs to know web development fairly decently before they can be introduced to, and expected to understand, Struts. That's a lot to fit into five days, especially considering they expect to start the course with people being relatively ignorant of the things they're teaching. I'm not knocking them :-) Just saying that it sounds as though that particular course is aimed more at POSAs (Plain Ol'e Servlet Applications) with a sprinkling of Struts.

MVC initialization
I know this is a bit off topic, but I figured I could get a better answer here. I am using Tomcat 4.1 and the latest production build for Struts in an MVC setup and have a large application already in production on the web. I need to enhance the model, but this enhancement will require me to have individual products/services register their interfaces with a common model hashmap. I would like this initialization to be done once at startup, but I am not sure where would be appropriate or where to do this. I don't need to include any properties files or anything, just need to do some initial setup and thought that static blocks for each service might be a bad route? What might be a good approach for this that people who do MVC use?

RE: Applicaton-specific logging in Struts
Yes it is possible Firstly you might want to make sure your log4j properties is on the classpath. Run a simple java test where you set log4 root level to various levels and check that a simple java application logging levels change appropriately Secondly I don't actually do it the way you are doing it. What I do is explicitely set my default logging level to WARN then turn on debugging for each individual package I want to check. It means that I don't get spam from random open source frameworks that I don't care about. In my experience most open source frameworks (struts and hibernate included) use logger.debug for useless information that only makes sense to the programmer who wrote it, and use logger.info for stuff that should clearly be debug etc. My attitude is that debugging should be helpful to a person *using* your code and trying to track down errors and only *significant* events should make up to info level. If it only makes sense to someone reading the source it should not make it into source control at all. -Original Message- From: Allen Day [mailto:[EMAIL PROTECTED] Sent: Wednesday, 1 December 2004 10:40 a.m. To: [EMAIL PROTECTED] Subject: RE: Applicaton-specific logging in Struts That didn't make any difference, but it was worth a try so thanks!

A search of the list archives turned up very little discussion of splitting forms across different tiles. I only found one person stating that you can split a form across tiles.

Tiles are certainly not broken; lots of people use them all the time, and even use them without using Struts. As for whether or not they understand what they're using... you've got me. Unfortunately while the form action gets correctly rendered with the right action passed from the jsp that uses the layout, the checkbox rendering fails with the message "Cannot find bean org.apache.struts.taglib.html.BEAN in any scope". As far as I understand this means the html form tag is not being put in scope for the checkbox to find. Actually, this means that the checkbox tag is not finding the form bean, not the form tag. The form bean object is looked up according to the action mapping associated with the value of the form tag's "action" attribute, and the object is placed into request scope, explicitly so that it would be available to other JSP fragments besides the one in which the opening form tag is invoked. If it is not found, an error is thrown by the form tag before the checkbox tag is ever executed. Have you ensured that this works in the simplest case, where you have a single JSP rather than tiles? If so, then we'd need more to go on - in theory, this is something which can be done. I've worked on applications which include form fragments using jsp:include, which should be similar enough for these purposes. I can't think of any offhand which use tiles instead.

There's a specific chunk of code in CommonsMultipartRequestHandler which has "ISO-8859-1" hard-coded as the fallback encoding if request.getCharacterEncoding() returns null. I brought this up on one of the struts lists when I encountered it a few months ago, but didn't feel satisfied of a correct way to expose the value as a configuration parameter. My concern was making it clear that setting it would only impact the request handler, because any configuration name I could think of might lead people to believe that Struts was also taking responsibility for calling request.setCharacterEncoding(...). In the last couple of days, we've been talking a bit about possible changes to Struts configuration, and I think Martin has some pretty big plans for file upload handling in Struts 1.3, and this hasn't been a big issue for many people, so we'll probably let it float a while longer still. > > setting the request encoding with a custom command in a chain-request >> processor, but the request was still returning a null value in > > CommonsMultipartRequestHandler where the non-uploaded fields were >> being processed.

Re: nested tiles
thanks Bill, your way to make nested tiles works fine. (After i changed "extends" to "template" in the second definition). It has the advantage that the jsp´s are smaller and easier to understand, but at the cost you need 2 definitions for each page. If you are only use one BodyFrame, you need a little more code i think. I hope there are coming a better documentation about nested tiles with some best practics in future. Stefan Bill Keese schrieb: Interesting. I'm not sure why your code doesn't work.

Re: Tiles and Forms
I don't think it is possible to "split" a form across multiple Tiles because the Tile is a complete (translated) response. A form must be complete on a Tile. However, you can achieve the desired behavior by using the JSP include directive -- the included fragment will can be a portion of the form; it will be included as part of the translation phase; prior to compilation of your JSP. -Bill Siggelkow Graeme Miller wrote: Simple question with no helpful responses so far.

Getting ActionMessages from session
Hi. I noticed that Struts 1.2.x has a new method saveMessages(HttpSession session, ActionMessages messages) that allows the ActionMessages to be stored in the session instead of the request. This is very helpful for displaying messages after a redirect. However, it doesn't seem like html:messages will display messages in the session (after my cursory test). The javadoc does mention that the messages are stored for use in html:messages. So all I'm doing right now is getting the message from the session in my action and then putting them in the request for subsequent display and then removing them for the session. I was hoping for cleaner integrattion. Are the tags supposed to display ActionMessages in the session (preferably removing them afterwards)? Alternatively, what approach should I take here? Thanks.

Check "required" validator in your validator-rules file - the message
takes one argument {0} is required - whereas in validation file you are
passing two values for 1 argument

Subject: Validator question
Hi there! I'm trying to make my validator projetct work on oc4j (oracle
10g) and so far I got no success at all.
First thing that is really strange is that at deploy time the
application runs it complains about some attributes being used but not
declared: " XML-0149: (Error) Element 'arg0' used but not declared."
well this doesn't seem to be affecting the application though.
But when I submit a form that uses validation nothin happens, I'm
submitted to a null page with this error on the stack:

What I really wanted to know was, how you would organize the controller/view in Struts for handling those standard create/update/delete actions.

If the request object returns null from > "getCharacterEncoding()", then Struts assumes ISO-8859-1. I was Isn't it Tomcat itself? This is a behaviour per servlets specifications (see page 41 of 2.4 specs). There's a specific chunk of code in CommonsMultipartRequestHandler which has "ISO-8859-1" hard-coded as the fallback encoding if request.getCharacterEncoding() returns null. I brought this up on one of the struts lists when I encountered it a few months ago, but didn't feel satisfied of a correct way to expose the value as a configuration parameter. My concern was making it clear that setting it would only impact the request handler, because any configuration name I could think of might lead people to believe that Struts was also taking responsibility for calling request.setCharacterEncoding(...). In the last couple of days, we've been talking a bit about possible changes to Struts configuration, and I think Martin has some pretty big plans for file upload handling in Struts 1.3, and this hasn't been a big issue for many people, so we'll probably let it float a while longer still. > setting the request encoding with a custom command in a chain-request processor, but the request was still returning a null value in > CommonsMultipartRequestHandler where the non-uploaded fields were being processed. Of course, this may have nothing to do with your situation. As far as I know, this is a behaviour per specifications. Page 41 and 198 of servlets 2.4 specs: changing the character encoding must be done prior to reading request parameters or reading input. Odds are high there is something which reads input before you set the request encoding. yes, you're probably right.

How can I convert the polish character, which the user has inputed? The problem is, in which encoding the browser is sending the data, and is it telling so (e.g. does the server has a way to know the encoding of the data it's receiving). Theoretically, when sending HTTP POST, browsers should put the charset= parameter in Content-Type and everything should be fine if the receiving server decodes that correctly. But, as far as I know, once, Mozilla tried to put the charset in Content-Type: field when replying with HTTP POST but had to remove this because it broke too many existing servers with bad configurations. However, I can't find the bug in their bugzilla again. The problem is worse with HTTP GET where there is really nothing to tell the encoding of the parameters passed. As far as I know, the most reliable way is to specify "accept-charset" as UTF-8 in the of the HTML (w3.org's description of this parameter: "This attribute specifies the list of character encodings for input data that is accepted by the server processing this form"). Theoretically, this forces the browser to send the data in UTF-8. As far as I know, tests showed that this should work correctly with current browsers. The problem is that this parameter is not available in from struts, the reason of it I have no clue about. This property was added in Struts 1.2.2, as noted on http://struts.apache.org/userGuide/struts-html.html#form In my experience, this is not as well supported by browsers as one would wish. My experience is that the most effective way to coax a browser to use a specific encoding when returning data is to send the page in the encoding which you want the browser to use when returning data. It looks like that's what's being done -- but be careful not to count on a JSP "page" directive in a tile, since only the "outermost" tile (the first one which writes to the response stream) has the chance to set the page encoding. Also note that Struts' multipart processing currently is rather clumsy in handling form encoding. If the request object returns null from "getCharacterEncoding()", then Struts assumes ISO-8859-1. I was setting the request encoding with a custom command in a chain-request processor, but the request was still returning a null value in CommonsMultipartRequestHandler where the non-uploaded fields were being processed. Of course, this may have nothing to do with your situation. In the case where I have a non-multipart form, I have consistently gotten suitable results simply by making sure that the form page is delivered to the browser with the character encoding I want to use.

Re: struts 1.2.2 to 1.2.4 upgrade conflict log4j
The Category class in log4j has been deprecated for a long time, and I recall some recent discussions on the commons-dev list about bringing commons-logging "up-to-date" with that. I don't remember the details, but basically you just need to have compatible versions of commons-logging and log4j. The project site for commons-logging or the commons-dev or commons-user mailing list archives may have more details.

Re: Automatic logging
Incidentally I use a HUGE amount of AOP stuff and logging is the only thing I am not using with it. I use AOP for the following Declarative security management ( down to filtering returned Collections by an ACL ) Declarative transaction management ( so that I don't have any transaction management garbage in my code ) Automatically managing hibernate sessions. In fact anywhere that you find yourself writing more boilerplate than business code or repeating the same code again and again and again ... you might find AOP saves you a lot of time and energy. --b On Mon, 29 Nov 2004 17:34:29 -0600, Joe Germuska <[EMAIL PROTECTED]> wrote: > >>Would there be a simpler way of enabling automatic logging across > >>entire application so that I do not have to modify all of my classes > >>and JSP pages? > > Sounds like the textbook use case for aspect oriented programming. > Logging is about the only thing they all talk about! > > But realistically, I'm with Eddie -- what logging can you really > apply consistently and automatically in a way that is more useful > than noisy?

Re: Automatic logging
Would there be a simpler way of enabling automatic logging across entire application so that I do not have to modify all of my classes and JSP pages? Sounds like the textbook use case for aspect oriented programming. Logging is about the only thing they all talk about! But realistically, I'm with Eddie -- what logging can you really apply consistently and automatically in a way that is more useful than noisy? If you have a bunch of fairly repetitive stuff spit out, then finding the real information is fairly tedious. On the other hand, I don't find it all that burdensome to establish a static log instance for each class and toss around a few log.debug(...) lines, especially when I'm working on figuring out someone elses ill-documented code! Unfortunately, I don't know a whole lot about AOP, but there has been plenty written about it in the last couple of years if you decide to look further.

Re: data caching in web application
I was going to say something along those lines as well. Create a class that represents a row in your table. Create an associated class that has knowledge of how to persist the data to the table i.e. CRUD methods. Populate the data's primary key (Or keys) and read it with a passed database connection. i.e TableRow tableRow = new TableRow(new TableRowPersister()); tableRow.setKey(1); tableRow.read(conn); Then you could do this via a Struts Plugin for all of the data you require to cache. If you Make TableRow extend a class that handles cahcing i.e. reads simply return the last copy of the data but all the other methods effect the table then you have what I think you need. The O'reilly book on Java Database Best Practices talks about it. I have a feeling that there is some framework that may do all that I have described. I would be interested to know if there is.

The problem is, in which encoding the browser is sending the data, and is it telling so (e.g. does the server has a way to know the encoding of the data it's receiving). Theoretically, when sending HTTP POST, browsers should put the charset= parameter in Content-Type and everything should be fine if the receiving server decodes that correctly. But, as far as I know, once, Mozilla tried to put the charset in Content-Type: field when replying with HTTP POST but had to remove this because it broke too many existing servers with bad configurations. However, I can't find the bug in their bugzilla again. The problem is worse with HTTP GET where there is really nothing to tell the encoding of the parameters passed. As far as I know, the most reliable way is to specify "accept-charset" as UTF-8 in the of the HTML (w3.org's description of this parameter: "This attribute specifies the list of character encodings for input data that is accepted by the server processing this form"). Theoretically, this forces the browser to send the data in UTF-8. As far as I know, tests showed that this should work correctly with current browsers. The problem is that this parameter is not available in from struts, the reason of it I have no clue about. Something you can try it to specify the encoding of the html page in which you have your form as UTF-8, it seems that mozilla will send GET/POST parameters in UTF-8 in such a case, but that's really a hack and I don't know browser support about it. And of course, on-the-fly detection of the charset is not reliable at all :). -- Guillaume Cottenceau - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Migrating to Struts
Hi, we recently migrated an application, which i consider large (about 100K loc java code) from XSLT / XSP / EJB to JSP / STRUTS / COD To be true we have not reused a single line of java code. We reused much of XSLT code in jsps, because the outgoing html had to look the same. We reused some of the javascript, still, we could reduce the amount of javascript by 50%, since we could move a lot of javascript functions into Jsps (things you can't do in xslt) To give you a more direct answer: It's possible to reuse the code, but you may take the chance and rewrite / refactor your existing code, since it will make it better :-) (at least it should in theory). We had to write a lot of tags missing in struts taglibs (equals with two parameters for example, or argXName+argXProperty for message tags) and we are still not really happy with tiles: a) because it's really freaking hard to debug errors in inserted fragments and b) because it has no fragment caching strategy (at least we found none). What we gained: We have a much clearer application now, we have a performance increase of nearly 900%, we are able to serve 1.5 more users with half of machines.

struts 1.2.2 to 1.2.4 upgrade conflict log4j
Hello all, I downloaded struts 1.2.4 yesterday to replace the 1.2.2 version that I am developping against. However, testing my application with the new jars (I copied all of the jars in the 1.2.4 tarball to the WEB-INF/lib directory of my webapp) generates an exception: [snipped] root cause javax.servlet.ServletException: org.apache.log4j.Category.log(Ljava/lang/String;Lorg/apache/log4j/Level;Ljava/lang/Object;Ljava/lang/Throwable;)V at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:497) at org.apache.jsp.index_jsp._jspService(index_jsp.java:70) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:136) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:204) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:289) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:240) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:193) [snipped] Is there something special I must do to make this work?

However, what I'm looking at is a non-intrusive, simple plugin kind of logging mechanism, only for the time being. We generally work out our own APIs, instead of directly using framework or technology specific APIS. By the time these are worked out, our guinea pig users are going have a go at the application for functional testing.
