using html:form with el logic tags
Hi,
Can someone tell me why I get an unbalanced error when I try to optionally
use a form tag?
org.apache.jasper.JasperException: /pages/common/layouts/layout.jsp(56,1)
The end tag /c:when is unbalanced
tiles:useAttribute name=action/
tiles:useAttribute name=focus/
c:choose
c:when test=${focus != 'na'}
html:form action=${action} focus=${focus}
/c:when
c:otherwise
html:form action=${action}
/c:otherwise
/c:choose
...
Using struts 1.1
Thanks
Simon

RE: using html:form with el logic tags
I'm going out on a limb here, but usually I wouldn't do the xml like that with
html:form since it is unbalanced...
You'll have to find a workaround I think...

Suppresing the generation of blank lines while using logic tags - Ver 1.0.2
Hello, We are facing problem of jsp file size exceeding to more than 5 MB at runtime. The jsp file is full of struts tag with lot many logic:equal, notEqual in the code. The compiled html when generated takes a lot of time for browser rendering because of the file size. Looking at the html source generated it seems the tags generates lots of blank line were ever used. If the source is modified to remove all the blank lines, the size reduces to 2 mb. I would appreciate any help on this issue. Thanks in advance.

RE: Suppresing the generation of blank lines while using logic tags - Ver 1.0.2
It's the newline between % and % that is causing you problems (not to mention the design of your page, but that's a different matter). If you do things like: ... %ns:tagname stuff=value %%ns:nothertag morestuff=morevalue %%... Then you will reduce the newlines in your output. This gets annoying to read, however. -Original Message- From: Pranay Parsatwar [mailto:[EMAIL PROTECTED] We are facing problem of jsp file size exceeding to more than 5 MB at runtime.

There is a Jasper servlet option which will remove the blank lines. Check for the trimSpaces attribute on the jasper servlet in the conf/web.xml config. However it is still going to take processing time to remove the white space, so it might not be the enhancement you are hoping for.

Use Apache and mod_deflate and mod_gzip. There are also Filters available to remove whitespace, but all of them have the problem where they'll modify code within a lt;pregt; tag or style.

Or you could use the JSTL conditional tag:
c:if test=${condition1 AND condition2 AND condition3}
your html

You can do an and test by nesting logic:xxx tags inside each other.
There's no convenient way to do an or test however; that's where the
expression language in JSTL and JSP 2.0 comes in very handy (if you're
running on a recent enough servlet container to support them).

logic tags
E.FAISAL
Hi
I would like to display the form data in JSP using logic:iterate tags.
Consider the following situation
ArrayList ar = form.getInfoContents();
for(int i=0;iar.length;i++)
{
HashMap row = (HashMap) ar.get(i);
tr
tdhtml:text property=name value=%=(String) row.get(name) % /
tdhtml:text property=age value=%=(String) row.get(age) % /
tdhtml:text property=address value=%=(String) row.get(address)
% /
...
..
/tr
}
In the above code i am getting a property of type ArrayList whose elements
are of type HashMap, where each HashMap object represents a record.
It works fine , but i want above code purely in struts tag logic:iterate or
some other technique.
I tried the following and it worked fine
logic:iterate name=beanname id=persons property=infoContents
tr
logic:iterate name=persons id=row
td
bean:write name=row /
/td
/logic:iterate
/tr
/logic:iterate
But in the above case i am not able to associate every value in the HashMap
object ie, row to a corresponding property like i got using for loop
tr
tdhtml:text property=name value=%=(String) row.get(name) % /
tdhtml:text property=age value=%=(String) row.get(age) % /
tdhtml:text property=address value=%=(String) row.get(address)
% /
...
..
/tr
please someone help me out and give the approach to solve the problem
regards
faisal

Iterating Simultaneously over Two Collections with Logic Tags
I've got a JSP that is display a list of information coming from two different collections and having trouble finding the cleanest way to do it with the struts tags. The line I'm struggling with is the bean:define where I'm constructing the name of the property using a scriptlet and the index from the iterate tag. It leaves a bad taste in my mouth. Is there a better way beyond bugging the other developers to combine the information into a different format that serves my display needs better? logic:iterate id=primaryRecord name=productSearchViewHelper property=primaryRecords indexId=i bean:define id=secondaryRecord name=productSearchViewHelper property='%=secondaryRecord[ + i + ]%' / bean:write name=primaryRecord property=description/ bean:write name=secondaryRecord property=description/ /logic:iterate Thanks, Jordan -- Jordan Reed | http://www.chaosserver.net | [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Nesting logic tags
Struts logic tags work fine nested in HTML table tags. Something else must be wrong, perhaps with your logic tag attributes. The nested tag library is for nested BEANS, not for nested tags. Unless you have Forms which contain Forms, or Forms with Collections of Forms, you don't need the nested tab library.

RE: Nesting logic tags
Well, I'm not an expert, but I can try. First, the obvious stuff I assume you know. ansm must be a bean you've exposed, right? If so, then it must have a getter method, getEntryType(). In order for the contents within logic:equal to appear, this method must return subformat [or group]. I *think* that if the ansm bean were not exposed, or you didn't have the getter, there'd be an error, so I guess that's not it. I would do a bean:write name=ansm property=entryType\ prior to the logic tags, and see what happens. m --- Kamholz, Keith (corp-staff) USX [EMAIL PROTECTED] wrote: Hm I don't see what would be wrong then.

Logic tags and collections?
How can I make something like this with Struts or someone have better idea?
I have few Admin: MainAdmin, UserAdmin, EmailAdmin.
MainAdmin can do anything, UserAdmin manage users and emails, and EmailAdmin
make emails only.
So, I need this:
-without Struts, I make Collection in session and
If session.getAdminTypeCollection contain MainAdmin {
do something
If session.getAdminTypeCollection contain UserAdmin OR MainAdmin {
do something
If session.getAdminTypeCollection contain EmailAdmin OR UserAdmin OR
MainAdmin {
do something
} End EmailAdmin
} End UserAdmin
} End MainAdmin
For MainAdmin Collection:
Collection.add(MainAdmin)
Collection.add(UserAdmin)
Collection.add(EmailAdmin)
For UserAdmin Collection:
Collection.add(UserAdmin)
Collection.add(EmailAdmin)
For EmailAdmin Collection:
Collection.add(EmailAdmin)
-do something are links
MainAdmin see all links
UserAdmin see UserAdmin and EmailAdmin links
EmailAdmin only EmailAdmin links
I can't use role or principal or anything from JAAS.
So, I need somehow to check Coolection with logic:present or some others
tags?
Thanks.

RE: Logic tags and collections?
First of all I would suggest you to reverse the if order so that, it the
first if returns true, you don't' have to perform the other if
statements(Like now, to get to a consistent result, you should perform all
the three if statements); secondly, you could iterate trough the Collection
retrieved from the session[by means of
(java.util.YourCollection)session.getAttribute? By means of bean:define
id=yourInternal name=yourSessionScopeCollectionName
type=java.util.YourCollection?]
and, depending on how many if are satisfied by logic:present, you could
show the consistent links.
My 2 cents.

RE: [Nested Tags] Nested vs logic tags..

RE: [Nested Tags] Nested vs logic tags..
Just a hunch-- have you tried specifying a 'name' for the nested:iterate tag? The nested tags don't need it, and if it's provided they will ignore it. Why?... because all the tags are working off the same bean structure, and this is defined for us by the form tag. The nested tags will fetch this bean. Because of this, all the nested tags within the form bean don't need the name property to be set.

Again using JSTL (Servlet 2.3 / JSP 1.2 container is required), you can
use the || operator to implement an OR:
c:if test=${(foo == '1') || (foo == '2')}/
... stuff when foo is 1 or 2 ...
/c:if
The expression language in JSTL 1.0 (and also in JSP 2.0, where you can
even use it in template text) is likely to become a JSP page author's best
friend. But if you're stuck on a Servlet 2.2 / JSP 1.1 based server,
you're best bet is probably to write your own custom tag that implements
the test you are after.

Re: [OT] Re: Avoid Heavy Use of Logic Tags ???
Would it hurt for struts to follow the 2.3 .jar layout? People using 2.3 could benefit from reduced deployment hassles while others could continue using the old way. Dave From: Craig R.

Thanks for the info Craig. I didn't know you didn't have to list them in the web.xml file and put the tlds in your app. Does this apply to any taglib on a servlet 2.3 compliant container as long as you use the uri given in the tld? Yes, this should work on any 2.3 container. The secret recipie: * The TLD (or TLDs, because you can have more than one tag library in the same JAR) has to be in the META-INF/tlds directory of a JAR inside the webapp, and have a *.tld extension. * Each such TLD must include a uri element with the canonical URI by which this tag library is identified. * These are the URIs you use in your %@ taglib % directives. Note that JSP 1.1 (which is the minimum required platform for Struts) allows a single TLD to be stored at /META-INF/taglib.tld, but that was not sufficient for Struts since we have several such libraries. Support for auto-scanning JAR files was also very inconsistenty implemented in JSP 1.1 containers, so I've stuck with the original style for Struts 1.1 examples and documentation. Once Struts formally adopts JSP 1.2 or later as the minimum platform, we'll be able to change that. Also, I switched from bean:message to fmt:message but then realized that the struts tag will pick the appropriate subapp resources. Is this the only difference from the jstl version? There's actually somewhat more to it than that for I18N. Most importantly, the fmt:message tag and its friends work off of resource bundles, not off of Struts MessageResources objects (although in practice, since both can operate off the same properties files, this is not a huge impediment). In addition, you can dynamically establish the default resource bundle (and/or locale) for i18n tags in a chunk of a page by using fmt:setBundle, or in a couple of other ways -- see Section 8.2 of the JSTL spec for details. I just thought it would be cool if containers recognized how cool struts is by optimizing the implementation of custom tags :-). Big players like IBM are putting an increasing emphasis on struts Indeed -- it was quite a rush for me to see an Add Struts Support button in the latest editions of WSAD :-). And they aren't the only ones ... so maybe in the future we'll see this. Certainly this is a feasible thing to do. In Tomcat land, one of the original goals of writing Jasper2 was to enable plugins for things like this, so it might someday be possible for Struts developers to create such a plugin (Tomcat-specific, of course, but there's *lots* of Tomcat users). On the other hand, I'm betting that the containers will go for optimized support on JSTL (and JavaServer Faces when it's done) before they would consider this. Although, considering how long it took them to release a 2.3 compliant Websphere this may be wishful thinking. Dave Craig From: Craig R.

RE: Avoid Heavy Use of Logic Tags ???
I agree...while looking back at some of my earlier JSPs, following the logic of those large and cumbersome scriptlets is nearly impossible. The succinct nature of struts (or any) tags do make the JSP more readable as long as you give the beans and properties functional names (common programming sense). The JSP should only contain presentation markup and the custom tags that facilitate that presentation (and maybe some optional javascript). -Original Message- From: Johannes Carlén [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 09, 2002 6:42 AM To: [EMAIL PROTECTED] Subject: Avoid Heavy Use of Logic Tags ???

... and now that we have the JSTL you can have your tags optimized into actual code.

I read somewhere that you should use http://java.sun.com/jstl/core for the
taglib uri in your web.xml file for the JSTL libraries (as opposed to
something you make up like jstl-core). The author stated that using that
full uri would allow a container to optimize those tags like you mentioned.
Each of the standard tag libraries in JSTl has a canonical URI, as defined
in the JSTL Spec. These are the URIs for the EL-based versions of the
libraries (which is what you'd use in preference to the RT versions that
do not recognize EL expressions):
Core: http://java.sun.com/jstl/core
XML:http://java.sun.com/jstl/xml
I18N Formatting: http://java.sun.com/jstl/fmt
SQL:http://java.sun.com/jstl/sql
It is by the use of these URIs that you specify you are talking about
*the* standard tag libraries. This is true whether or not your container
has built in optimized support for JSTL or not.
NOTE: If you use the JSTL RI (or the Apache version of it, the standard
tag library from jakarta-taglibs), you'll note that you don't have to
separatel copy the TLDs into your WEB-INF directory as is conventional for
Struts apps. That's because they are included in the META-INF directory
of the JAR file (supported under Servlet 2.3/JSP 1.2 containers). You
also don't have to explicitly list these TLDs in your web.xml file -- just
drop the appropriate JARs into /WEB-INF/lib and start using JSTL tags in
your pages.
First, is that true? Second, it would be neat if containers optimized
Struts tags in a similar manner. Maybe the Tomcat team would be willing to
do this since they're both on jakarta.
Containers have the *opportunity* to provide optimized support for JSTL
tags, and I understand that Resin does this already. But you can use an
implementation of the JSTL tags on any container, just like any other tag
library, by including it in your app.
As cool as Struts tags are :-), any container developer (including those
building Tomcat) are going to get a lot more bang for the buck by
supporting the standard tag libraries first. That's one of the main
reasons that I encourage people to migrate to JSTL instead of the
struts-bean and struts-logic equivalents, along with the fact that the
expression language makes these tags substantially more powerful. For
example, think of what you'd have to do to make this work with the Struts
tags:
c:if test=${(cust.status == 'OPEN') || (cust.status == 'ONHOLD')}
Customer account is either open or on credit hold
/c:if
And in JSP 2.0, you'll be able to use EL expressions anywhere in your
template text, not just in the attribute values of tags that understand
it. Learning the EL syntax now will give you a head start on the future.

Re: [OT] Re: Avoid Heavy Use of Logic Tags ???
Thanks for the info Craig. I didn't know you didn't have to list them in
the web.xml file and put the tlds in your app. Does this apply to any
taglib on a servlet 2.3 compliant container as long as you use the uri given
in the tld?
Also, I switched from bean:message to fmt:message but then realized that
the struts tag will pick the appropriate subapp resources. Is this the only
difference from the jstl version?
I just thought it would be cool if containers recognized how cool struts is
by optimizing the implementation of custom tags :-). Big players like IBM
are putting an increasing emphasis on struts so maybe in the future we'll
see this. Although, considering how long it took them to release a 2.3
compliant Websphere this may be wishful thinking.

Yes, this should work on any 2.3 container. The secret recipie: * The TLD (or TLDs, because you can have more than one tag library in the same JAR) has to be in the META-INF/tlds directory of a JAR inside the webapp, and have a *.tld extension. * Each such TLD must include a uri element with the canonical URI by which this tag library is identified. * These are the URIs you use in your %@ taglib % directives. Note that JSP 1.1 (which is the minimum required platform for Struts) allows a single TLD to be stored at /META-INF/taglib.tld, but that was not sufficient for Struts since we have several such libraries. Support for auto-scanning JAR files was also very inconsistenty implemented in JSP 1.1 containers, so I've stuck with the original style for Struts 1.1 examples and documentation. Once Struts formally adopts JSP 1.2 or later as the minimum platform, we'll be able to change that. Also, I switched from bean:message to fmt:message but then realized that the struts tag will pick the appropriate subapp resources. Is this the only difference from the jstl version? There's actually somewhat more to it than that for I18N. Most importantly, the fmt:message tag and its friends work off of resource bundles, not off of Struts MessageResources objects (although in practice, since both can operate off the same properties files, this is not a huge impediment). In addition, you can dynamically establish the default resource bundle (and/or locale) for i18n tags in a chunk of a page by using fmt:setBundle, or in a couple of other ways -- see Section 8.2 of the JSTL spec for details. I just thought it would be cool if containers recognized how cool struts is by optimizing the implementation of custom tags :-). Big players like IBM are putting an increasing emphasis on struts Indeed -- it was quite a rush for me to see an Add Struts Support button in the latest editions of WSAD :-). And they aren't the only ones ... so maybe in the future we'll see this. Certainly this is a feasible thing to do. In Tomcat land, one of the original goals of writing Jasper2 was to enable plugins for things like this, so it might someday be possible for Struts developers to create such a plugin (Tomcat-specific, of course, but there's *lots* of Tomcat users). On the other hand, I'm betting that the containers will go for optimized support on JSTL (and JavaServer Faces when it's done) before they would consider this.

Re: Nesting Beans/Iterators/Logic tags whatever else...
There are many applications for the tags use -- even out side the iterate process Hell yes! :) I suppose some people will just see it as a way past their nested iteration problems, but it brings so much more. Among other things, it will clean your JSP's because the markup's reduced for those tags working off the default bean for the form/root tag. This is just one of the benefits. The tags literally extend the original Struts tags so the do exactly the same things, but in an improved markup context. Fact is, I've seen so many people in this user group use nested beans (anyone using dot notation in their properties, is nesting), and they can manage that so much easier if they go to the nested context. Personally, it's a kick in the a-- of those other templating engines. I haven't heard of people moving over to them because they offer a better OO approach to their markup.

setting a default bean for logic tags
Is it possible to set a default bean for logic tags like it is for form tags so that they don't have to be named in each logic tag? If I don't specify the name in an html:text tag, the name from the parent form and its corresponding action tag will be used. For example, in the below html:text tag, fooForm will be used as the name from the parent form since the name is not specified. action path=/foo type=FooAction name=fooForm scope=session input=/foo.jsp ... html:form action=/foo html:text property=bar/ /html:form Is there a way to do this with logic tags? I have lots of redundant logic tags that need to use different beans, but since I have to have a different value for the name on all of them, there's no clean way to reuse the JSP.
