nested tags again - Q

[Maya Muchnik]

Hi,

Maybe this question was posted already. I am sorry for the repetition.
Can somebody suggest what is the best case to resolve this expression
(maybe nested tags are not working):



value of domainID is still  <%= >

Thank you all in advance.

Maya

Re: nested tags again - Q

[Scott Walter]

I have never been able to get that to work,  I think
it's an issue with either tomcat of the java spec.

The way I have been able to get around this is to
write my own tag and have the tag set page context
attributes via a tag extra info class.

Thank you, Scott,
If this is not a company "secret" can you share your tag?

RE: How can a Struts Action developer best document the system for a JSP developer?

[Brugge, John]

Title: RE: How can a Struts Action developer best document the system for a JSP developer?





Bryan,


You might check out a recent article on JavaWorld called "Doclet your Servlet" (http://www.javaworld.com/javaworld/jw-03-2001/jw-0302-doclets.html) that describes a custom doclet that understands some custom doc tags. It would probably take some customization to work with Struts Actions, since it looks like it uses introspection to look for instances of true servlets.

I've been thinking of the same problem, and think that you could get pretty good mileage out of a simple XSL template that transformed the struts-config.xml into a clearer HTML description of the actions, their navigation and form expectations. It could handle #2 and #3 below easily; #4 and #5 would be harder. You could even tie this into the JavaDoc of the ActionForms by creating links from the form names to the area where your JavaDoc lives.

I'm not an XSL expert, but I've done some transforms before and figure this wouldn't take very long to create - the key for me is just finding the time now ;-). If I come up with something, I'll forward it to the group, unless someone beats me to it.

I am struggling right now with how to properly and efficently document 
my Struts application for my JSP developer (who is by no means a Java 
expert). Specifically, I want to document each Action as well as each 
ActionForm that I code, including things like:


1. the pages I expect the user to have come from
2. the pages to which I might forward, or redirect, the user after 
completing the action
3. The beans I expect to be in place prior to submitting to my action
4. The beans I will set up with values for the resulting JSP page to 
work with
5. The errors () I may set up


And anything else that might be appropriate. I'd like to do so in a way 
that lets me rely on Javadoc, so that I can keep my documentation inside 
my code. Javadoc when used correctly will also let me do things like 
"see also" the Bean documentation (from the Action documentation).


I am curious if anyone has developed a "template" action or bean, which 
makes best use of Javadoc and which I can cut-and-paste at the head of 
every one of my Action classes, etc?


Thanks,
Bryan

remembering selected option question

[John Wright]

Maybe a newbie question here:

If a request is sent to a JSP page that has a   tag but the
request does not include a parameter with the same name as the property
attribute of the  tag it is my understanding that an exception
will be thrown saying that the request must contain the parameter.  If this
is the case how do you handle cases in which you want to remember the
selected option when there might be other screens accessed in between the
times when the screen with the  tag is accessed?

Thanks,

John

It's not clear to me whether this will help you, but you might want to
read a current article on JavaWorld titled "Doclet your servlet!",
about writing a JavaDoc "doclet" to augment the generated
documentation for servlet classes.

html:link and ssl

[harald . ruf]

Hallo,

I have some problems with the struts html-tag link with the 
properties forward or page. I want to use this tag with ssl. It doesn't 
create the link, because the method in  
org.apache.struts.util.RequestUtils throws in the method 
absoluteURL a MalformedURLException because unknown 
protocol. 
Do I need some additional package for ssl? Or is there a other 
solution?

Thanks for help

I'm not quite sure I understand your question completely, but the general
philosophy in Struts works like this:

* Requests are submitted to an Action (via the Controller servlet)
  rather than being submitted directly to a page.

* The controller servlet can associate a form bean (an instance of
  ActionForm) with the request, in order to capture the input fields
  from that request.  You would have a property to capture the current
  state of the property you are using  on, for example.

* If you need to keep the information about what was selected for more
  than one request, the typical approach would be to store the
  corresponding form bean in the user's session.

This is not legal JSP syntax.  You are not allowed to nest custom tag uses
inside an attribute value.

The closest you can come is to use JSP scriptlet expressions to go get the
data you are looking for.

Could you give an example of how you are trying to do this?

Note that trying to use the "page" attribute only works within the current
web application (the path you give it is context-relative beginning with a
"/").  To go to a different web application, or to switch from SSL to
non-SSL or back, you will need to make sure you generate a redirection,
either by using the "href" attribute, or by referencing a 
element that has redirect="true" on it.

Locales and images

I understand Struts has support for makeing web apps available in different
languages.  Does this include images?  If I have images with text on them in
English can I make images with text in French as well?  Do I name the image
files differently or do I have to include the paths to the images in the
property files?  Has anyone done this?  What's the best approach?

500 lines of jsp is 10k lines of java

[Kurt Olsen]

Hi everybody,

I'm fighting a problem whereby the java code generated by a 500 line jsp
file is so large (10,200) lines that a try/catch block contains so much code
that the file won't compile, giving a msg saying something like 'jump target
out of range'...

Surely I'm not the first to deal with this (and it's a real show-stopper).
Anybody know a way to deal with this (other that hand editing the
source-code)?

This isn't a struts problem per-se but it's being interpreted that way by
the powers that be where I work. Not good!

Later,
Kurt

There was a recent addition to the  and  tags to
support internationalized images elegantly.

Previously, you had to use the "src" attribute to specify the URI of your
image.  If you needed different images for each language, you had to use a
scriptlet expression of some sort to calculate them.

Now, you can specify a message key (to be looked up in your application
resources) instead:



where "message.key" identifies the path to this image from your
application resources.

If you want to use context-relative paths everywhere, use:



instead.

Re: 500 lines of jsp is 10k lines of java

[jbirchfield]

It isn't a struts problem, it is a problem caused by using excessive custom
jsp tags.  One fix is to break your page up over several pages and use
dynamic includes.  This will fix he compilation problems, but introduces a
few new challenges.  The problem you are dealing with is the 64k limit in
java methods.
The entire jsp is compiled into a single _jspService method.

Re: 500 lines of jsp is 10k lines of java

[pdw]

There is a limit to the size of a compiled method in java, I think it's 64k,
it's probably not specifically related to the try/catch block.  Split it up
into multiple jsp's and use includes to make it into one page.   It seems to
me that a good jsp compiler should generate multiple methods, but I don't
know if any actually do that.

Re: html:link and ssl

[harald . ruf]

Hallo,

here is my example:

struts-config:
  
..  

..
  

an now I want to use in every page something like this:


..
login 
..


I don't want to switch from ssl to non-ssl. I am using the whole time ssl. But the 
link wouldn't be create.

Example for testing page:




<%=pageContext.getRequest().getScheme() %>
<%=pageContext.getRequest().getServerName() %>
<%=pageContext.getRequest().getServerPort() %>
<%=((HttpServletRequest)pageContext.getRequest()).getContextPath() %>

 <%java.net.URL url = new java.net.URL(request.getScheme(),
  request.getServerName(),
  request.getServerPort(),
  request.getContextPath());%>
   <%=url.toString()%>

index




When I request this page with: http://myserver/mycontext/index.jsp I get back:
http
myserver
80
/mycontext
http://myserver/mycontext
 login (as link)
When I request this page with: https://myserver/mycontext/index.jsp
I get back:

Exception:
java.net.MalformedURLException: unknown protocol: https at 
java.net.URL.(URL.java:307) at java.net.URL.(URL.java:224) 

I hope this will explame my problem in more details.

What do you mean by "not from the first column".

I think, you are correct to qualify this as a formatting. Take the
struts-example. The tag  at the beginning of each file
will display error messages at top and left corner of a page.

Performance of struts

[Keith]

Hi,
   I am sorry if I offend anyone. I am evaluating struts and notice that the
performance is much lower that if I use string jsp and servlets.
   Has anyone have the same experience as I do? If so, is there any way to
improve the performance?

Re: display errors

[David Winterfeldt]

I started working on an alternative version of the
errors tag this weekend that iterates through the
results so you can leave HTML out of the message
resources.  It doesn't do everything that the Struts
tag does at this point.  It also automatically
includes errors.header and errors.footer.  Maybe you
could use this or modify the code to do what you want.
 Or you could always use a iterate tag to loop through
your errors and format them the way you want to.

How do I really bypass the deficient of a HTM editor?

[Keith]

Hi;
  I am new to struts, and thought I would be great if I can completely
separate the HTML and web design from the java code. So, I tried out the
first few pages of a project with struts implementation, only to realize
that the web designer will not be able to see his design because all the
custom tags cannot be displayed.
   Consequently, I search in the mailing list archive, and notice that many
people are having the same problem as I do. I came across a thread in which
the author suggested embedding HTML code in the custom tags to enable the
web designer to see the placement of the widgets. Everything seems to work
except when I tried to use  tag to display labels. Struts
complains about not allowing content in this tag.
   Has anyone have the same problem? How do you let the web designer does
his design without having to guess the position of the labels and boxes?

Thanks
keith

Re: Performance of struts

[Maya Muchnik]

I think, it will be slower because you have one central servlet DISPATCHER that
is sending a "job" to different Actions. When you have some JSP that are
sending "job" themselves to other JSP, it is faster. Is it convenient? I think
- no, because a creator JSP does not know java. And change flow, redesign
difficult.
Now, I have this "pie".

Re: struts-template tag library vs.

[Jim Newsham]

Thank you for your reply, but this didn't really answer my question.  Let me
rephrase.  I am talking about , which is a dynamic templating
mechanism, as opposed to <%@ include %>, which is static.  As I understand it:

 and  are both dynamic templating mechanisms
-- they are re-evaluated at runtime whenever referenced.  They allow you to
create a template with placeholders for dynamic values which you will supply at
runtime.  This is where they are similar.  What I'm interested in hearing is
how they differ.

I assume that struts-template offers some improvement over jsp:include,
otherwise it serves no purpose.  So my question is, what does struts-template
offer as an improvement over jsp:include?  The answer may be as simple as "it
provides a consistent and readable syntax", or it may be more substantial.

Thank you,

Jim Newsham

RE: struts-template tag library vs.

[Troy Hart]

the biggest thing for me is that you limit the potential layout bugs, and
you make it possible to change the layout, site wide, with the editing of a
single file. The alternative (just using ) forces you to
replicate the layout framework (typically this includes a set of nested
tables where you set the header, footer, sidebar, and etc...) on every
single jsp page.

REPOST: How to handle an extra button on login page

[Shamdasani Nimmi-ANS004]

Hi,

I want to add an extra button 'Change Password' on my logon screen, which should take 
me instead to the 'changePassword.jsp' screen where I would enter the username, 
password, new password fields .

I want a suggestion on how to handle this. Should I have the same form bean for both 
logon.jsp and changePassword.jsp? If yes then the validate method of the form bean 
cannot do validations like,e.g. check for the new password and confirm new password 
fields to be non-blank because these fields are not on logon form.

Also the validate() method of the form bean would get called when I click on 'Change 
Password' button and since username and password would be null at that time it would 
return errors.

I would really appreciate if someone could tell me how they handled such a situation.

Thanks in advance.

You can use the name-value parameter of your Change Passord button (Submit

have that information you can write the logic based on it.

I'm mostly concerned about the execution speed of the generated servlets.

Yes.  For example, Tomcat (more precisely, the Jasper component) does not
currently recycle custom tag instances -- this is in the process of being
addressed.  Also, the code generator is very simplistic, does essentially
no optimizations, and generates more code than it really needs to.

This is not surprising, given Tomcat's heritage as being a "reference
implementation" for the specs, rather than a high performance production
environment.  To the extent that people want to turn Tomcat into the
latter, it will improve.

Take a glance at the code that is generated for any custom tag, and you'll
see what some of the issues are.

The Jasper in 4.0b1 is almost identical to the one in 3.2.1 right now,
although improvements are being done on both of them.  But Jasper really
needs a fresh start, IMHO, to achieve substantial performance boosts.

RE: How can a Struts Action developer best document the system fo r a JSP developer?

[Derek Longmuir]

Title: RE: How can a Struts Action developer best document the system fo r a JSP developer?





Hi Bryan and John,


I have created something like this with XSL that converts the (old) action.xml and (new) struts-config.xml files and produces a graph showing the various forwards, forms, actions, etc. I then use dot to convert the graph into a gif.

It isn't quite as enlightening as I thought it would be, but certainly produces interesting pictures. :-) This is primarily due to the fact that the struts-config.xml doesn't hold all the information - I think to produce a better overview you would have to also parse the corresponding JSPs for their tags, and maybe even the action classes themselves. 

I was planning on refining it a little more before releasing it to the list, but I'll work on getting it up on a web page in the next couple of days for you. John, maybe you can take it and add what you think is missing. :-)

Thanks, Derek.

Bryan, 
You might check out a recent article on JavaWorld called "Doclet your Servlet" (http://www.javaworld.com/javaworld/jw-03-2001/jw-0302-doclets.html) that describes a custom doclet that understands some custom doc tags. It would probably take some customization to work with Struts Actions, since it looks like it uses introspection to look for instances of true servlets.

I've been thinking of the same problem, and think that you could get pretty good mileage out of a simple XSL template that transformed the struts-config.xml into a clearer HTML description of the actions, their navigation and form expectations. It could handle #2 and #3 below easily; #4 and #5 would be harder. You could even tie this into the JavaDoc of the ActionForms by creating links from the form names to the area where your JavaDoc lives.

I'm not an XSL expert, but I've done some transforms before and figure this wouldn't take very long to create - the key for me is just finding the time now ;-). If I come up with something, I'll forward it to the group, unless someone beats me to it.

5. The errors () I may set up 
And anything else that might be appropriate. I'd like to do so in a way 
that lets me rely on Javadoc, so that I can keep my documentation inside 
my code. Javadoc when used correctly will also let me do things like 
"see also" the Bean documentation (from the Action documentation).

html:img tag cannot find image

Hello all,

It seems that the html:img tag is able to find images in the context
root, but not in subdirectories.
When I specify an image with the html:img tag like this:

the images appear.

But when I specify a subdirectory like this:

the images are missing when the page renders, i.e. little red X symbol
in the browser.

Here is a pared down JSP that illustrates the problem. It gives the same
results whether I include the  tag or not.

I'm using Struts 1.0b1 and Tomcat 3.2.1.

TIA for any help.

RE: html:img tag cannot find image

[Cook, Levi]

Title: RE: html:img tag cannot find image





Hi Tom,


In your example, you are directing your web browser to request an image file from within the "WEB-INF" directory. Per the servlet specification your servlet engine treats the "WEB-INF" directory as a private resource. This means none of the files it contains may be served directly to a client.

Try moving your /images directory out to your applications document root and you should have more luck.


For more info. on this, check section 9.4, "Directory Structure", of the servlet spec at http://java.sun.com.

The issue is that a servlet container is prohibited (in the spec) from
serving any file from the WEB-INF directory directly to a client.  This is
to prevent people from snooping sensitive information from your web.xml
file, or other config files you might have stored here.

If you want your image to be displayed, move it to some directory other
than WEB-INF.  Then, the URLs you use with the  tag will
correspond to what you would use with a regular HTML  tag.

If Tomcat's performance is pretty awful, what are some JSP implementations

RE: struts-template tag library vs.

[Troy Hart]

The template custom actions (including "insert", "put", and "get") are
absolutely distinct from the JSP "include" action. I would recommend that
you review the code for the struts-template web application that comes with
struts1.0 beta 1. In a nutshell, the template allows you to define a single
template page that lays out a set of components by referencing the
components by name.

Let's say the following is the contents of a file called
"/somePageLayoutSetup.jsp":
---
<%@ taglib uri='/WEB-INF/tlds/struts-template.tld' prefix='template' %>






---

Now then, here is the template, "/myTemplate.jsp":
---
<%@ taglib uri='/WEB-INF/tlds/struts-template.tld' prefix='template' %>










I can also put any static stuff that I desire directly on this layout
template...

---

This is obviously a simple example but it illustrates the point. Namely, you
have a page that references a layout template and "put"s named components
into a context such that the referenced template can "get" at them.
Obviously, the power here is that for any given page on your site you only
need to know what the components of the layout are, not how they are laid
out. When you want to change the way they are laid out you only need to
change the layout JSP (assuming components don't change). The mechanism that
is used by the  action is (as I understand) functionally
equivalent to, if not exactly the same as, that used by the  (when the named element was "put" with "direct='false'", which is
the default).

Like I said initially, a review of the "struts-template" web app. will clear
this up for you.

Good luck,

Troy

Thank you for your reply, but this didn't really answer my question.  Let me
rephrase.  I am talking about , which is a dynamic templating
mechanism, as opposed to <%@ include %>, which is static.  As I understand
it:

 and  are both dynamic templating
mechanisms
-- they are re-evaluated at runtime whenever referenced.  They allow you to
create a template with placeholders for dynamic values which you will supply
at
runtime.  This is where they are similar.  What I'm interested in hearing is
how they differ.

I assume that struts-template offers some improvement over jsp:include,
otherwise it serves no purpose.  So my question is, what does
struts-template
offer as an improvement over jsp:include?  The answer may be as simple as
"it
provides a consistent and readable syntax", or it may be more substantial.

Thank you,

Hi Bryan and John, 


I have created something like this with XSL that converts the (old) action.xml and (new) struts-config.xml files and produces a graph showing the various forwards, forms, actions, etc. I then use dot to convert the graph into a gif.

It isn't quite as enlightening as I thought it would be, but certainly produces interesting pictures. :-) This is primarily due to the fact that the struts-config.xml doesn't hold all the information - I think to produce a better overview you would have to also parse the corresponding JSPs for their tags, and maybe even the action classes themselves. 

I was planning on refining it a little more before releasing it to the list, but I'll work on getting it up on a web page in the next couple of days for you. John, maybe you can take it and add what you think is missing. :-)

Thanks, Derek.

Bryan,
You might check out a recent article on JavaWorld called "Doclet your Servlet" ( ) that describes a custom doclet that understands some custom doc tags. It would probably take some customization to work with Struts Actions, since it looks like it uses introspection to look for instances of true servlets.

I've been thinking of the same problem, and think that you could get pretty good mileage out of a simple XSL template that transformed the struts-config.xml into a clearer HTML description of the actions, their navigation and form expectations. It could handle #2 and #3 below easily; #4 and #5 would be harder. You could even tie this into the JavaDoc of the ActionForms by creating links from the form names to the area where your JavaDoc lives.

I'm not an XSL expert, but I've done some transforms before and figure this wouldn't take very long to create - the key for me is just finding the time now ;-). If I come up with something, I'll forward it to the group, unless someone beats me to it.

I am struggling right now with how to properly and efficently document
my Struts application for my JSP developer (who is by no means a Java
expert). Specifically, I want to document each Action as well as each
ActionForm that I code, including things like:
1. the pages I expect the user to have come from
2. the pages to which I might forward, or redirect, the user after
completing the action
3. The beans I expect to be in place prior to submitting to my action
4. The beans I will set up with values for the resulting JSP page to
work with
5. The errors () I may set up
And anything else that might be appropriate. I'd like to do so in a way
that lets me rely on Javadoc, so that I can keep my documentation inside
my code. Javadoc when used correctly will also let me do things like
"see also" the Bean documentation (from the Action documentation).
I am curious if anyone has developed a "template" action or bean, which
makes best use of Javadoc and which I can cut-and-paste at the head of
every one of my Action classes, etc?

RE: Performance of struts

[Robert Taylor]

Currently I'm using ServletExec-AS (with Apache) on Win98 and it seems
pretty easy to use and relatively fast. It also has a nice admin interface
for deploying and defining web apps.
You can download it from http://www.servletexec.com/download.jsp. I don't
think you have to enter any information. I believe the only limitation is
that an un-registered version gives you up to 3 concurrent connections. I've
also been able to get Cocoon running pretty easily which I have never been
able to do with Tomcat. I don't have any real metrics to offer though.

Struts based apps (or any app that uses custom tags heavily) are going to
be significantly impacted by the quality of the JSP implementation in your

Pass all values from a listbox to the formbean

[SPandith]

Hi,

I have the following problem:

I have 2 listboxes (select boxes) - Input and output.
The input box is populated when the jsp is loaded.
At this point the output listbox( select box) is empty.
The user selects a value in the input box and clicks on the add button which
puts the value in the output box.
The user is able to choose the same value from the input box that was
previously selected.
It is designed that way so that the user can choose the same value and have
different names. this is done for a good reason 

Now my question is how do I send the contents of the output listbox without
using hidden form fields?

RE: Performance of struts

[Eric Brown]

I haven't done any comparisons recently, but I think Resin from
www.caucho.com is very reasonably priced and written specifically with
performance in mind (from what I can tell). I've written a Java based http
proxy server before and I can tell you that from looking at some of the
things Resin has done, they know where Java's performance bottlenecks are.
(For example, they translate all socket streams into byte arrays instead of
using strings, etc.) They have some performance comparisons on their web
site.

Others are:
Orion - Know nothing about
BEA WebLogic - Very expensive, complex to deploy and performance is mediocre
according to my sources
ATG Dynamo - Expensive but good for commerce if needed. They are focused on
commerce, so probably not focused on performance.
Netscape/iPlanet - I've heard the performance is not impressive
IBM WebSphere - This is an up-and-coming competitor to WebLogic and ATG. It
used to be buggy and is still expensive. Performance is unknown, but I would
favor Resin as it comes with source and is less expensive.
Jrun - Priced reasonably. Nice integration with other Allaire products. No
special commerce features. I think it has had some compatibility problems,
but it seems a good engine these days. All the same, I don't think you can
get source and I haven't done performance tests.
Enhydra - This is just Tomcat. They have their own framework that is less
comprehensive than struts called XMLC. Its big advantage is that it does a
better job of separating UI from code.

I think to some degree, it is equally important to look at the JVM you are
running on. Consider looking at the Volano report at
http://www.volano.com/report.html.

My team is using Tomcat/Forte for development and will use Resin/Apache for
deployment.

ActionForm. What I am trying to do is utilize a factory for creation of my
ActionForms. In my application, I have a base (abstract) ActionForm class
called Fermentation, and subclasses FermentationYeast, FermentationEcoli,
etc...  The factory is called from my Action servlet to create the
appropriate instance of an ActionForm (a subtype of Fermentation). Then I
save the newly created ActionForm in the session. The object type that gets
saved in the session is the subtype, but in my Struts config I am specifying
the base type. I want Struts to read this object from the session, but
Struts always creates a new ActionForm of the base type. I want it to find
and use the subtype!

For example, the Action servlet calls the factory and the factory returns a
FermentationYeast. This object is saved in the session, and then I forward
to the EditFermentation page. The EditFermentation page is mapped in the
Struts config to use a Fermentation form, so Struts does not recognize the
FermentationYeast that is already in the session and it creates a new
ActionForm. Even though a FermentationYeast *is a* Fermentation, Struts does
not seem to support this. I think it would be helpful if Struts supported
generalization... or if it does and I am missing something here please let
me know :) Or, If you think I should change my design, please let me know
this as well.

I think I have a good reason to need to do this. The first page is where the
user enters common information, then the next page is loaded based on the
type of the Fermentation (ActionFrom). I could create 2 separate ActionForms
(one for the common attributes and then another for the details) but I would
like to use inheritance to model this relationship. In other words, I want
to create a single ActionForm which will be used across multiple pages, but
I want to share pages that ask for the same information.


Thanks,
Bob

reloading issue

Hi all, I’m new in this list so please be patient. I looked into docs
and mail archives, and deja but couldn’t find a solution to the problem. Every time
I make a chance in the formbean, action, jsp, or the strut-config.xml file, I
have to stop and restart Tomcat. Is this necessary (if yes, dang!), if not how
can I correct this (making every change not requiring restarting Tomcat)?

Thanks

As far as i know, you have to take the pain, except 
for the JSP changes

hi Ali,
 
A change in a jsp does not warrant a restart but the 
others do. Any change in struts-config or an action class is not reflected 
otherwise. A changed form bean will sometimes throw an exception too.
Cheers,
