SAX warnings when compiling JSPs using Taglibs - 5.0.30
Hi, I don't know when this started to happen but suddenly those warning messages started to show up every time a JSP page is compiled. Has anyone got these message before, if yes how do we get rid of these? ParserUtils: warning org.xml.sax.SAXParseException: URI was not reported to parser for entity [document] ParserUtils: warning org.xml.sax.SAXParseException: No base URI; hope URI is absolute: http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd ParserUtils: warning org.xml.sax.SAXParseException: No base URI; hope this SYSTEM id is absolute: http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd ParserUtils: warning org.xml.sax.SAXParseException: URI was not reported to parser for entity [dtd] ParserUtils: warning org.xml.sax.SAXParseException: missing system ID, using http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd Here is a snippet from my tld file : ?xml version=1.0 encoding=UTF-8 ? !DOCTYPE taglib PUBLIC -//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd; taglib tlib-version1.0/tlib-version jsp-version1.2/jsp-version short-nameflow_taglib/short-name uri/flow_taglib/uri display-nameflow_taglib/display-name descriptionTaglib to simplify flow2 layout/description /taglib and this is how in load the taglib in the JSPs files: [EMAIL PROTECTED] uri=/WEB-INF/tlds/flow_taglib.tld prefix=flow% Thanks -- Jean-Francois Beaulac [EMAIL PROTECTED]
Jakarta - taglibs
hi , Can we use jakarta Tag Libs to connecting to a database via JNDI and select an images from BLOB data field ? and aslo can we use that tags to having Links for each images ? That Links also stored in the database ? Can we display images randomly with the appropriate links ? if it is possible , can somebody give me some examples ? Thanx Kane. __ Do You Yahoo!?

Extra newline characters appenden to taglibs output?
Hello, I use Tomcat 5.0.30. I have problems with taglibs generated from tagfiles. Tomcat appends extra newline character at end of tag output.

Problem using Ditchnet Tab Taglibs
Hi, Has anyone used this taglib before? I am not able to display the image of the tab. The author said it is a known issue when it deploys in Window. So does anyone have a solution for this?

Re: Reflection for custom taglibs killing performance...
Its not reflection killing you. For example, time this:
%=System.currentTimeMillis()%
c:forEach begin='0' end='${param.iterations}'
${more.cowbell}
/c:forEach
%=System.currentTimeMillis()%
Where more is any java object and cowbell is a property (getCowbell()). In
simple timing trials - even where iterations is greater than 2000 - I get
subsecond response time.

I think something else is going on here then. I actually rewrote the
above code to use a custom tag which I KNOW is slow in our system and
even with 1 entries its very fast.
Though when I took our production code and converted it from .tag files
to jspfs it was 100x faster.
So the issue is what has changed between the two code bases to make it
THAT much faster.
Its got to be some caching system or so forth. Maybe Tomcat can only
cache so many methods and is recreating them.
So its clearly not JUST reflected methods its something else on top of
it
Any other ideas?

Re: Reflection for custom taglibs killing performance...
To execute a tag file requires creating some new objects which migh have an
overhead not quite comparable to RequestDispatcher.include()
Thats probably the issue.

Reflection for custom taglibs killing performance...
I've been spending this week running a profiler across our webapp and Tomcat. We've had a few bottlenecks in our code that have since been removed but the remaining big bottleneck is Tomcat. The JSP engine is creating compiled code that is heavily relying on reflection. Reflection shouldn't hit the page too much but we have tight loops over say 400 items or so and each uses 10-20 taglibs. This is resulting in about 800ms of page load time.!!! After rewriting the taglibs to use jspf includes the page load drops 10x to about 80ms. The bottleneck is gone and the pages essentially snap on the screen. Very fast! :) Our app still has 2200 ms that can be shaved off if I could just get rid of reflection within taglibs. The problem is that I'd like to continue to use taglibs and I'd like to to avoid rewriting our code. Is there ANY way to get Tomcat to not use reflection in this situation. I'm running Tomcat 5.5.4 if it helps. Thanks. -- Use Rojo (RSS/Atom aggregator)! - visit http://rojo.com. See irc.freenode.net #rojo if you want to chat.

How could a tag work without reflection?
For example, if you use any of the expression-language features, how is
Tomcat supposed to react to, say,
${request.somvar.something}
without dynamic invocation?
While I doubt you could make Tomcat not use reflection (without
completely hacking the source) perhaps you could share more details of
what you're doing... that may give the rest of us insight to help you
trim the bottlenecks more. i.e. you mention lots of looping and
tag nesting; is there any way to change how that's done?

I'm not sure about this mechanism but if you take a function like:
c:set var=test value=${foo:bar()} /
and rewrite it to use
c:set var=test
foo:bar/
/c:set
Then it won't use reflection.
This is why c:set and c:choose and so forth work so well.
There isn't a perf penalty here.
So this means I'll have to rewrite all my function calls to elements
that are in tight loops.
There's also no reason that it MUST use reflection. I mean its a CODE
generator so all you have to do is generate code that doesn't use
reflection and calls the methods directly.
There.s about a .5ms overhead for reflected functions and if you have
1000 on a page (EASY!) then it will be DOG slow.

Well I think I'm going to have to review all forms of code that cause
this and rewrite them.
The BIGGEST problem as I currently see it is with .tag files. These use
reflection but I can't figure out a way to rewrite them.
I think if i were to do this it would yield DRAMATIC performance
improvements.
The REAL issue is that enabling developers to shoot themselves in the
foot like this is really irresponsible and probably needs to be removed
or a HUGE warning be placed before examples.

Jasper 2 problem with core taglibs in 5.5.7?
Hi folks,
I have a Ant build which includes pre-compilation of JSPs. This has been
working happily during prototyping with Tomcat 5.5.4, but has broken now
that we have moved to Tomcat 5.5.7 as the latest stable build, which
worries me a lot.
The error I get during the build is:
org.apache.jasper.JasperException: The absolute uri:
http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml
or the jar files deployed with this application
The Ant task:
target name=define-jasper2-task
taskdef name=jasper2 classname=org.apache.jasper.JspC
classpath
path id=jspc.classpath
pathelement location=${java.home}/../lib/tools.jar /
fileset dir=${tomcat.dir}/server/lib
include name=*.jar /
/fileset
fileset dir=${tomcat.dir}/common/lib
include name=*.jar /
/fileset
fileset dir=${lib-dir}
include name=*.jar /
/fileset
/path
/classpath
/taskdef
/target
${lib-dir} contains jstl.jar and standard.jar, and the line in
the JSPs causing trouble is:
%@ taglib uri=http://java.sun.com/jsp/jstl/core; prefix=c %
I understand this sort of error to be typically to do with JSTL1.0/1.1,
but I don't think this is an issue here, especially as 5.5.4 works fine.
The ONLY thing I change is the value of ${tomcat.dir}. Has anyone seen
this, or can anyone suggest a resolution?
Thanks,
David Kennedy

Re: TagLibs must be cached
I'm not sure I understand the question, but you know that you can use the enablePooling parameter to set if a jsp tag should be pooled or instanciated for each use. see : http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jasper-howto.html it's set to true by default I think. hope it helps, reynir Edson Alves Pereira wrote: Hello folks, i noticed that everytime tomcat-5.0.x needs a taglib it just create a new one, i´d like to cached all tag in my JSPs, how ca i do that?

Re: Another doubt about taglibs
Thats one way to do it. My prefence is to stuff most of the data that is in
scriptlets into a single java object, then into the HttpServletRequest (or
pageContext).
Then the custom tag can query the HttpServletRequest or PageContext. To get
the dynamic data. It avoids the %% hell that you see below.
Another alternative is to use EL with custom tags in tomcat 5. Then
%= (request.getParameter( hdnTypeCTRL ) != null ) ?
request.getParameter( hdnTypeCTRL ) :texto %
becomes the slightly less ugly: ${param.hdnTypeCTRL?param.hdnTypeCTRL:'texto'}

Jspc and Taglibs
I made several measure, had a look to the generate code by Jspc. It is clear that Taglibs reduce the performance (memory, speed) of your server. Speed because the first time access is longer and memory because a pool system is there to make the next pages being displayed quicker. So, as a developper, I'm wondering if the Tomcat gurus are aware of all of that and if they are taken some actions. For example, I think that it is a (good or bad ?) idea to try to transform the taglibs instructions into scriptlets (like preprocessing in C) and then compile the JSP pages. I am using JSTL recently and I am happy because my JSP are now scriptlet-less BUT the performance are hit. I tried a few days to make a preloading system to fill the different pool, but it not seems possible. Anyway, I'll keep JSTL because it is a good choice for maintaining easier your JSP. I think there are a few steps to make all that very powerfull. What do you think ? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

You could just put the tld in WEB-INF and reference it from the web.xml.

Is the settter for dType setdType(String value) or setDType(String

RE: Error using taglibs - unable to find setter
The following comes from the Tomcat 3.3.x faq file, which I assume
would apply in your situation:
Q. I have a bean with a property whose second letter is capitalized.
Why won't my JSP page that uses this bean compile?
A. This may not happen often, but can be difficult to determine why.
The reason is found in the Java Beans specification, where in section
8.8 Capitalization of inferred names it states:
Thus when we extract a property or event name from the middle of an
existing Java name, we normally convert the first character to lower
case. However to support the occasional use of all upper-case names,
we check if the first two characters of the name are both upper case
and if so leave it alone.
This means that if you have a bean with a setter method of setXLoc,
then the inferred property is XLoc, not xLoc. If you used this
bean in a JSP page and you tried to use xLoc as the property, it
would not compile. Using XLoc as the property would succeed.
If you insist on using xLoc on the JSP page, you can make this possible
by creating a BeanInfo class for the bean. The following is an example
of such a BeanInfo class for a simple bean called Coordinate. It
explicitly defines the properties of the bean to be xLoc and yLoc.
import java.beans.*;
public class CoordinateBeanInfo extends SimpleBeanInfo
{
private final static Class beanClass = Coordinate.class;
public PropertyDescriptor[] getPropertyDescriptors()
{
try {
PropertyDescriptor xLocDesc =
new PropertyDescriptor(xLoc,beanClass,getXLoc,setXLoc);
PropertyDescriptor yLocDesc =
new PropertyDescriptor(yLoc,beanClass,getYLoc,setYLoc);
PropertyDescriptor [] pdv = { xLocDesc, yLocDesc };
return pdv;
} catch (IntrospectionException e) {
throw new Error(e.toString());
}
}
}
HTH.

Re: Error using taglibs - unable to find setter
I have a similar problem with a simpler situation. I have a simple JSTL
tag and bean that alternate the colors in a table. If delpoyed under
JBoss 3.0.7 with Tomcat 4.1.24 it works. If I deploy it under JBoss
3.2.3RC2 with Tomcat 5.0.24 I get the same Unable to find setter method
for attribute: XXX that you're getting. I've also tried it under a
stand alone version of Tomcat and get the same error.
I've tried finding the error using Eclipse 2.1.3 and Idea 4.0.2 but
neither report any warnings or errors.
Any ideas for a solution would be appreciated.

The line in the jsp uses the tag that i created. the tag has the
setter method for dType.
The same taglib is working in the application that is presently
deployed in weblogic. We are trying to migrate the same to
tomcat and I am getting the above error.
Any clues?
Thanks in advance

I created a tag which extends from the html:text tag.
I'm using tomcat 4.1.30.

Taglibs help needed???
Hello All, I am having some strange problem using taglibs in tomcat 4.1.27 and jdk1.4. My webapp named 'hris', works well without taglibs. I am using 2.3 dtd which i refer as http://java.sun.com/j2ee/dtds/web-app_2_3.dtd. I have downloaded the taglibs standard library (not standard-1.0) from apache website and its standard-examples webapp works fine when deployed and run as a seperate webapp. However if I add the tag-libs tag element in my hris webapp, the tag-lib does not work. I deployed it as taglib taglib-uri/tag/taglib-uri taglib-location/WEB-INF/taglibs-input.tld/taglib-location /taglib and in my jsp page use %@ taglib uri=/tag prefix=input % However I get an error message The absolute url /tag cannot be found I have tried several different ways and no matter what I do, I get the same error from 'hris' but the standard-examples works ok. I am baffled and stuck. Any help or suggestions will greatly help. thanks -sumit - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Problem in rtexprvalue-attributes with taglibs in Tomcat 5.0.16
String typed rtexprvalue-taglib-attributes worked well with tomcat 4.1xx. Running same taglibs with tomcat 5.0.16 gives an error like org.apache.jasper.JasperException: /ksite/index.jsp(91,4) Unknown attribute type (String) for attribute lan. Is there any workaround to this Thanks in advance, -George-

Tomcat with embedded java database and taglibs
Hello, I'm currently looking into what solution to use for a web application I'm about to create. What I want is: - Taglib support. core, sql, and maybe things outside the standard-taglib - Pure Java database to run embedded in the application for easy deployment. Does anyone have any experience with a similar setup, and by that any recommendations on what config to choose? Any example applications available?

Fw: Jasper Compilation with Ant including custom taglibs
To make the picture more complete:
it seems that the trouble the Jasper compiler doesn't find the
/WEB-INF/web.xml file.
But how can I tell it where to find it (simply creating it directly under
my project directory didn't work)?
If I include other custom taglibs with reference to e.g.
/WEB-INF/forms.tld it doesn't find them as well.
So the question is:
How can I tell the Jasper Compiler where to find the /WEB-INF/web.xml or
/WEB-INF/forms.tld.

My directory tree structure:
===
/web/WEB-INF/web.xml
/web/WEB-INF/forms.tld

Hi taglibs .. is this a tomcat or JSP problem or feature ?
Hi, I have a custom tag. Inside the tag i am accessing a database and populating a vector. The contents of the vector are then rendered as HTML by using the tag on a JSP page. Problem is that when i add new data to the database and refresh the page being rendered. It does not show me the new data. Does the tag handler get executed each time a page is refreshed or not ? Thanks. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Taglibs are not interpreted with Tomcat 4.1.18
Hello Thorsten, List, I am far away form being a pro with this but it seems to me I have the same problem with an out of the box app. It's only a beta but all concerning taglibs seems fine within the app (it's running for other people on other tomcat versions) and on the other hand the taglibs just can not be found by tomcat 4.1.18. three possible conclusions: a) there is an error with the tomcat versions 4.1.18/19 (tested it with .19 also) b) it's a more general error in our configurations c) sth else Maybe you could think about b) At the moment I have no time to do more research on this, if you can find out sth it would be nice if you'd post it here.

More comments on taglibs, struts and architecture.
Web tier Architecture: Abstract: Handling page logic tier - scriptlets not so bad; struts needs page tier. Is seems to me that the MVC model 2 architecture fails to address an additional stage of logic. Beyond the business logic, there is really a whole additional tier - the page layout logic tier- and this tier is often more complex and problematic than the buisness logic tier. The issue is dealing with a system that may have 100 different pages, all not too different from each other. When can the same jsp be used to render mutlitple pages using page logic, and when should a page, or set of pages be rendered with a whole new jsp? In our applications, there are hundreds of pages that are often only slightly different - and the requrements are simply unknown and unknowable. As we go online, the users begin experimenting with the system, and come up with new ideas and requirements. As we complete a part, the requirements for the next part of the system are changed. So we need an approach that is stable and flexible. Personally, I think it is a much bigger SIN to put business logic in a tag library, than it is to use scriptlets in a jsp page to handle page logic - especially since the current architectual ideas ( MVC model 2 and the framework Struts ) seem to completely ignore the page logic tier. The problem with the page logic tier becomes much more problematic with a site using frames. For non-frame based control flow, the output from the action class is inserted into the request object, and forwarded to the jsp - so the data elements are encapsulated and short lived - after the jsp uses the data in the request object, the request object expires. However, with a frames based site, the output of the action class must be inserted into the session object, and then the forward is to a framset which is downloaded to the browser. Each frame then fectches its own jsp page from the server. So, the data response to the initial http request is inserted into the session object, and if the connection breaks to the browser, maybe never used - and left dangling around in the session object. The struts framework has a tier for processing the data input (action forms) that includes a data object ( the form bean) and two default methods, reset() and validate(). The struts frameworks has a tier for handling the business logic - the Action class which can handle the businees logic, calling other ordinary java classes for help. But, once the data has been built, there is nothing in the struts framework for organizing the output. I've started to use a page tier. With a website that uses frames, and where the back button is expected to work, and where the user may open multilple browser windows during the session, this can be a mess. The business logic output from multiple action classes, and to support multiple framset and the consequent jsp fetches, all become a jumbled mess in the session object. Thanks, James

Hi All, Is it possible to assign default class includes and/or tag libs to an entire webapp? I assume i could put all of the declerations in an include but it would be cleaner if there was a property of a webapp to assign defaults. Thanks for any help, Rick -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: Shared JSP taglibs
- All the webapps running in this Tomcat installation must share the same version of the tag library (or whatever -- it's not just limited to these), so you have to upgrade them all together in lockstep. Ah, but that's exactly what I want! :-) We have a fairly atypical situation here where our system is implemented as a group of loosely connected webapps that all look like the same application to the user. Some of our tags exist to provide a standard look feel across these webapps, so obviously we don't want them to fall out of sync. Currently, the tag handler classes are in a shared JAR, and the tlds are shared using SourceSafe links into each webapp's WEB-INF directory. It's workable but not perfect. I know that JSP 2.0 requires that the JSTL be made available by the container, so I'll just let it be known for Tomcat 5 that it would be nice if there were some kind of shared taglib directy where we could just drop taglib JARs and have them automatically available to every webapp. Thanks! -- Tim Moore / Blackboard Inc. / Software Engineer 1899 L Street, NW / 5th Floor / Washington, DC 20036 Phone 202-463-4860 ext. 258 / Fax 202-463-4863 -Original Message- From: Craig R.

4.01 vs Jar'ed taglibs and /META-INF/taglib.tld in jarfile itself
For most of the weekend, I've been trying to get a working taglib I developed inside Forte 4 to successfully run from a jarfile -- classes AND .tld -- with no success. After checking the bug report, it appears that 4.0.2 and 4.0.4 didn't handle jar'ed taglibs properly. Seeing how 4.0.1 is apparently the version integrated with Forte 4, is it safe to assume that trying to make it work in Forte is a lost cause for now? The scenario: The taglib's package is com.skubick.flashbar, and was developed within a Forte 4 web application with the source and compiled class files in the web app's /WEB-INF/classes/com/skubick/flashbar directory. The .tld file itself was there too (for CVS convenience). web.xml defined the taglib with: taglib taglib-uricom.skubick.flashbar/taglib-uri taglib-location/WEB-INF/classes/com/skubick/flashbar/flashbar.tldtaglib-l ocation /taglib and the page itself included it with %@ taglib uri=com.skubick.flashbar prefix=nav % In that environment, it works perfectly. To create the jarfile, I used Forte's jarfile wizard to add /WEB-INF/classes/com and /WEB-INF/classes/com/skubick/flashbar/flashbar.tld, then manually specified the .tld file's directory as /META-INF and its filename as taglib.tld After compiling the jarfile, I extracted it to a temp directory using Winzip to verify that its internal structure was correct. It was. I unzipped it into c:\temp\flashbar and ended up with two directories: com/ and META-INF/ com/ contained everything it was supposed to contain, as did META-INF/ (MANIFEST.MF and taglib.tld) To test it, I created a new Forte project, created a new directory, mounted it as a filesystem, and converted it to a web application. I copied the jar file into /WEB-INF/lib, and updated the new project's web.xml file to specify the jar'ed taglib: taglib taglib-uricom.skubick.flashbar/taglib-uri taglib-location/WEB-INF/lib/flashbar.jar/taglib-location /taglib UNFORTUNATELY, attempting to actually use it (from a new page in the new web app containing the exact same %@ taglib % command as before, and the same block of taglib tags) generates the following error: No such tag insert in the tag library imported with prefix nav I'm beginning to wonder whether Tomcat is even finding the jar file. If I change the uri (com.skubick.flashbar) specified in either the taglib declaration in the jsp page or in web.xml, I get a complaint that the file wasn't found. HOWEVER, if I change taglib-location in web.xml to something blatantly invalid (like taglib-location/cold/day.hell/taglib-location I get the same No such tag insert in the tag library imported with prefix nav error as before. Any ideas or suggestions as to how I might either make it work, or at least conclusively establish that it's a lost cause and will never work with the Tomcat 4.0.1 embedded in Forte? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
