Integrating Jakarta taglibs in Jdev 9.0.4 (other than JSTL)

Hello --
I'm having difficulty getting the magic spell for proper integration of Jakarta taglibs other than the JSTL taglibs to work.
I've gone into Tools->Manage Libraries->Jsp Libraries and created a new Jsp library based on the .tld file / archive file / and uri, and assigned a prefix, but I can't use it.
If I create a workspace from a WAR for something like 'application-examples.war' from the Jakarta site, when I try and compile the example page, I get a "Attribute 'xmlns:xalan' is used but not declared."
and Jdev is unable to load the taghandler class.
Has anyone had any luck getting these taglibs to integrate properly?
Thanks,
Donn

Ok, now I'm going nuts. I can't get JSTL working either -- have tried with the <taglib> directive in web.xml, and without, have tried with registering the libraries in the JSP tab and not registering, and with the .tld files in the lib directory and not.
Any successes out there?

What is the condition of the jakarta taglibs project?

I have downloaded the most recent build of the jakarta taglib and have
          found more bugs than I expected. Is this application in bad condition
          or am I missing something?
          Thanks


Main purpose is data persistence. If you don't need that, then EJB isn't that important.

Downloading jakarta taglibs

Hi all,
I'm working on a JSF 1.2 project and need some functionality that I have found in a project called "jakarta taglibs IO": http://jakarta.apache.org/taglibs/doc/io-doc/intro.html
I did however notice that the download links aren't working anymore and the project is marked as deprecated.
Can anyone help me where to get this taglib or otherwise if there is an alternative for its functionality?
Thank you,
Steven

Thanks for the help.
The problem I must solve is a pain in the ass for quite a while now. Basically what we have is under tomcat 2 web applications, a dynamic and a static one (for the images and static html files).
What I am trying to do is to include a static html file from the static context into a jsp file in the dynamic context. I have failed to do that by jsp:include and it also didn't work out properly with <%@ include file="" %>.
Any ideas?

Jakarta taglibs vs jstl

I am currently downloading everything I need to know to learn JSP. I came across jakarta taglibs which also mentions jstl. They are in the sameplace everywhere. Are these two technologies the same or different? Do they work on all web containers?

JSTL is the standard.
The Jakarta taglibs build on JSTL and go above and beyond.
These taglibs should work in all servlet/JSP engines that support the 2.3/1.2 servlet/JSP standards.
You have to be a bit careful, because the 1.0 JSTL only works with Tomcat 4.0.x. The 1.1 JSTL is intended for Tomcat 5.x.

Jdev Extension Jar put in a directory other than "JDEV_HOME/jdev/extensions

I'm creating new rules for auditing using the Jdeveloper 10.1.3 extension API and enabling using extension framework. Once I created the rule, I placed the 'jar' file in "JDEV_HOME/jdev/extensions/" directory as per the guidelines. It is executing perfectly. But I want to place the jar in my home directory. is it possible?
I mean I place the jar file in my home directory and I will provide classpath in 'extension.xml' file, which is a part of jar file. How can I achieve it?
The 'jar' file contains
a) extension.xml
b) 2 java files
c) one text file.
Here extension.xml mention the link of a rule to the audit framework. I used the
A part of extension.xml file which adds my rule to the framework.

<addins>
<addin>oracle.test.launcher</addin>
</addins>
</jdeveloper-hook>
</hooks>
I heard that we can do this in different types:
a) In <hooks> tag, we can include the <libraries> tag which mentions the classpath tag and value.
But no where I found the <libraries> tag in google search.
b) In "JDEV_HOME/jdev/extensions/" directory we place a jar file which only contains the 'extension.xml' file and we can specify the class path of the jar file, which contains the remaining three files. is it possible? If so pls. show me the pointers to do this.
Could you pls. suggest me.
Thanks in Advance

Hi,
You can install extension jars in your jdevhome extensions directory in addition to the standard OH/jdev/extensions. On platforms other than Windows, this is ~/jdevhome/extensions by default. On Windows and other platforms, the location of the jdevhome directory can be controlled using the environment variable JDEV_USER_DIR.
Adding an extension jar to one of those two locations is usually sufficient to add it to the classpath of JDeveloper. If you have additional non-extension jars you want to add to JDeveloper's classpath, you can do so using the <classpaths> element in extension manifest. This contains <classpath> elements which are relative paths to jars from the location of the extension jar. For example, say you have
~/jdevhome/extensions/my.extension.10.1.3.jar
and you want to include
~/jdevhome/someotherjar.jar
You would use something like this:
<extension ...>
<classpaths>
<classpath>../someotherjar.jar</classpath>
</classpaths>
</extension>Thanks,
Brian

Jdev 10.1.2 problem define jstl tagLib

hi,
i have a problem in my jsp when i compile it with JDev 10.1.2, when trying to use JSTL tag:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
I always get the following message:

Error(34,18): Invalid element 'description' in content of 'context-param', expected elements '[param-name]'.
but i saw this tutorial http://www.oracle.com/technology/products/jdev/tips/schalk/taglibs/taglibs.html
and i check my preferences about my projet, i had the libraries standart.jar and jstl.jar to my project (Project Properties->Profile->developement->Libraries), and they are located in my <project>/public_html/WEB-INF/lib/
And for the declaration of the taglib,
Tools->Manage Libraries-> JSP TagLibraries the prefix "c" is defined, and it is the same uri what i'm using in my jsp.
I make another with jdev 10.1.3, and i put my project, i compile and it work very fine.
Thanks for any help.

How to configure SOA in Integrated WLS Server for JDEV 11.1.1.1.0

Hi,
I am trying to deploy a SOA Application but it says No SOA Configured targets found. How can I configure SOA on Integrated Weblogic Server in JDeveloper.
Thanks

Okay, so the Admin server controls the connection. Is there a screen that shows this? My JDev is reporting that the soa server does not exist, though the WebLogic administrator shows that it's there.
I have checked the AdminServer.log and the soa_server1.log files and found nothing that would indicate an error. I also noticed there is something called a Work Manager. wm/SOAWorkManager This guy is pointing to just the soa server.

Weblogic Integration and Taglibs

Has anyone thought about having a taglib for using Weblogic Integration, (specifically
the BPM) for simplification of accessing workflow information.
I think this would be a very useful taglib.
any comments?

From that perspective, WebLogic Integration is simply a set of applications, tools, and APIs that are deployed into WebLogic server instances. A WebLogic Integration Java Process Definition is compiled into EJB components and deployed to the server instance. The following provides a good overview: [http://edocs.bea.com/wli/docs102/overview/index.html]

Jakarta taglibs

hi all,
Is it true that by using the jakarta i18n taglibs, the properties files are preloded into the memory. How exactly do they work.
Is the working different from using
ResourceBundle.getBundle().
please help
thanka in advance

Yes, it is perloaded in memory, That is why when you make some changes in property file then you have to restart the application

Integrating Reports Builder with JDEV

Hello,
I am studying how integrating a Report builded using Reports Builder with JDEV, because when I run from JDEV my JSP file which contains Reports, I am not manage get success. However, if my JSP has not Reports, then I get success in the execution. When I am running the JSP with has Reports, in the execution, the following error messages are displayed:

Hello Carla,
The link indicated by Philipp just move to this URL
http://otn.oracle.com/products/reports/htdocs/getstart/GettingStarted/index/index.html. (Sorry for that)
Watch the Reports/JDev integration viewlets in the demonstration section.
To be able to execute a Reports JSP from JDev you should be in the JDeveloper of the 9iDS. (9i Developer Suite). You can also check you Jdev 'Run' property to check if the Embeded OC4J server starts with all IIOP parameter. (FYI:a Reports JSP communicate with the Reports Server using Corba)
1. Right click on you project in the system navigator
2. Choose 'Project Setting'
3. In the Runner Entry you should have a Java option like :
-Dorg.omg.CORBA.ORBClass=com.inprise.vbroker.orb.ORB -Dorg.omg.CORBA.ORBSingletonClass=com.inprise.vbroker.orb.ORB
(This option is automaticaly added if you select New, Reports JSP from JDeveloper)

Working with taglibs in jdev 10.1.3.4 (to be used for facelets)

Short question:
How do I get the jdeveloper to accept this declaration: <em><%@taglib uri="http://java.sun.com/jsf/facelets" prefix="ui"%></em> and its elements, such as <em><ui:include></em> ?
Full story:
I've been trying to get facelets to work in a project I'm working on. A part of this project, which I have no control over, is automatic javascript insertion via xslt, which makes it impossible for me to use xml style documents. (due to '<'>' being used for comparison, rather than tag opening/closing. Having said that, here's my problem:
I want to use jsf / facelets to create a template page, that will be used in about 30 other pages. If I was able to use an xml-style jsp docuement, I could add an xmlns:ui, and faces support would work. However, since the above is true, I have to define the taglib in jsp style, to be able to use facelets. This would look something like:
<blockquote>
<em><%@taglib uri="http://java.sun.com/jsf/facelets" prefix="ui"%></em>
</blockquote>
Upon doing this, jdeveloper tells me that
<blockquote>
<em>Error(7): "http://java.sun.com/jsf/facelets" is not a registered TLD namespace</em>
</blockquote>
and for any uses thereof:
<blockquote>
<em>Error(33): ui:include is not a registered tag in that namespace.</em>
</blockquote>
After I add the jsf-facelets.jar library (tried versions 1.0.1.14, 1.1.11, 1.1.14), nothing changes.
I understand that Jdeveloper wants to validate the taglibs I define, but there is no tld in the jsf distribution and there also should be no need for this (in xml-style syntax, it works fine without validation).
If there's any way I can skip this validation or make jdeveloper believe the library is valid, I'm done. However, I have not been able to find such a function.
Some guy from exadel has uploaded a tld for facelets to the facelets project (it's under contrib, here ). This tld has been referenced in most threads that deal with the problem (jsf in jdeveloper). The tld can't however provide a structural solution, since it's not complete. The <tag-class> and <tei-class> tags within the tld are empty. Reason enough for jdeveloper to halt on it.
Adding the library to jdeveloper would be done thus: go to tools, go to 'manage libraries', go to 'tag libraries' click 'user' and select 'new'. Browse your way trough your filesystem and locate the tld file. Add a reference to the jsf-facelets and a reference to the el-api and el-impl jars and click ok. Then go to project properties and under tag lib libraries, add this library.
Jdeveloper responds to this with the following error:
<blockquote>
<em>Error(33): Unable to instantiate tag: ui:include (class: null) Make sure that the tag class is available and that the tag library containing the class is not excluded from this application.</em>
</blockquote>
Right. To be able to instantiate the tag, jdeveloper seems to not only need the description of the tag, but also the connection to the real thing. I've been exploring the jsf-facelets jar and came to the conclusion that the tags in the tld correspond to the classes in the 'com.sun.facelets.tag.ui.' package, so for ui:include, that would be 'com.sun.facelets.tag.ui.IncludeHandler'.This class, described here here, seems indeed to have the same attributes as our ui:include tag. Tag tei-tag (tag extra information), is, afaik, not mandatory, so I'll leave it empty. Rebuild in developer gave me lots of errors when I did it the first time (which I solved by filling in the other tag-classes), but when recreating it for this topic, I had no problems of that sort. The error I'm stuck with is:
<blockquote>
<em>Error(33): src is not a property of com.sun.facelets.tag.ui.IncludeHandler</em>
</blockquote>
I'm baffled by this statement. The tld says this property exists, the ui:include documentation agrees with me and the file I'm linking to has a src TagAttribute (for which I'm having trouble finding the setter, but it worked in the xml-style version). Using this tld Jdeveloper grants content assistance, which suggests to me that I should use the src tag. It is mandatory.
I tried to fill in the <tei-class>'es, but the facelets jar contains no class (that extends from) tagExtraInfo, as far as I could see. Using the one from jsf (facelets are, in a manner, jsf tags, being just a viewHandler for jsf), didn't change anything.
At this point, I'm stumped. I hope there is either
- a way to disable the tld resolution feature
- a way to make a change in the tld I have now and make jdeveloper parse this tld
- a way to create some dummy tld that jdeveloper will accept
<blockquote>
<em>Error(33): src is not a property of com.sun.facelets.tag.ui.IncludeHandler</em>
</blockquote>
How can I get rid of this error? Thanks for any suggestions!
edit: fixed some typos and messed-up links on 04-Nov-2008 04:35
Edited by: user2103934 on 04-Nov-2008 06:07

Opon further expirimentation, I've discovered that the facelets view handler can not handle the <%@ taglib > declaration, returning me an
com.sun.facelets.FaceletException: Error Parsing /mapviewer.jsp: Error Traced[line: 3] <Line 3, Column 2>: XML-20201: (Fatal Error) Expected name intead of %.
With the facelets handler off, the non-xml facelet declaration is handled fine, but is no help.
Which means I'm bound to use the xml style for facelets, which means I'm going to have to catch the inserted javascript in some manner.
In any case, the original question in this topic is not the problem anymore, so I closed it here and awarded 5 points for a helpful answer.

How to install ADF Desktop Integrator on mac (using jdev 11.1.2.1.0)

Hi Everyone,
I got a requirement for my client where they want to use microsoft excel to upload/edit/delete content of one of our ADF application data and we are thinking of using ADF Desktop Integrator option for achieving this. I tried to install ADF Desktop Integrator from my Jdeveloper->Tools->'Install ADF Desktop Integrator' but this option got disabled on my mac. Is there any way to enable it or is it mac not compatible for ADF desktop integrator tool? Also most of my client team members are using mac and hence I cannot ignore mac option and switch to pc.
Any help or suggestions on this would be very help and appreciated.
Thanks,
Ravi N

Hi.
ADF Desktop integration relies on Microsoft .NET and Microsoft Internet Explorer; both are available on Windows only. Thus, ADF Desktop Integration is not available on Apple OS X.

Jakarta taglibs and iWS4.1

Is it possible to use the Jakarta custom tag libraries with iWS4.1 SP11?
I am able to make the custom tag samples work (http://docs.sun.com/source/816-5680-10/2-examp.htm#21044). But I can't figure out how to plug in the pre-built custom tag libraries from Jakarta.
My goal is to use XSLT to dynamically display XML documents. It runs on Tomcat, but it needs to run on iWS4.1
Any input is greatly appreciated.
Thanks

This is not an Apache site. It is not even the Oracle JSP forum.
I suggest you try the JDeveloper site, which you will find JDeveloper and ADF, where at least they all speak Java. There is also the J2EE forum, although that seems somewhat less OC4J. And of course there is a designated Java Server Pages (JSP).
Cheers, APC

Integration of icefaces in jdev 11gTP2

Hi,
I want to know if it is possible to integrate icefaces with TP2 or any other framework
Thanks

Hello Mourado,
Yes it should be possible. However, take note that JDeveloper 11 is a JSF 1.2 environment and ICEFaces requires some hacking to work under JSF 1.2, see http://www.icefaces.org/docs/v1_6_0/htmlguide/gettingstarted/configuring_other4.html#1021196.
