Server says Custom Tag is readonly

I am now trying to use the Jrun tag library with the orion server which is suppose to be tag neutral and am running into a bug that says the Jrun SqlTag library is readonly. oc4j howto says to simply add tag library to /WEB-INF/classes or WEB/INF/lib directory and add taglib directive to JSP file. Did this and get readonly error. Anybody know why this is so?
null

This is due to a Sun bug in the JDK when using the "classic" VM. If it's the same problem I'm familiar with, then you'll see that it goes away when you run with -hotspot
Here's what our engineer said about the problem I reported.
The actual problem is in java.beans.Introspector when consolidating types for
properties. The consolidation depends on the order of methods returned by the
reflection code of the particular VM, which it shouldn't!!! This is a Sun bug.
The method(s) in question are java.beans.getTargetPropertyInfo() and
java.beans.addProperty(). addProperty() is called by
getTargetPropertyInfo(). Depending on the order of methods returned by
reflection in the array methodList, a composite property descriptor for
numItems will or will not be created in addProperty() although it always
should be created for the example!null

Custom tag lib, tomcat server cant parse descripter file

Hi there, I'm working on custom tag libraries, and I have created a simple tag which prints a string when it is called from a jsp file. And I have created a descriptor file for that perticular tag and also created a jsp file which is using the tab lib that I have created, I have placed all these files in their corresponding files, well the problem is when I'm trying to call that jsp file it says the server can't parse the tags.tld file, because <urn></urn> must be declared. And can anybody throw some light on this! it would be much of help from you side, regards, Raasi

Allthough this program are run on NetBean6.1.In NetBean6.1, i am not specify the web.xml file.Please Help me..

With an [HTTP status code|http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html] of 500, the most helpful information for debugging the problem is usually in the server's log file. There should be a stack trace in the web or application server's log file that will contain the specific root cause of this. It is often a NullPointerException or ClassNotFoundException or other "common" exception.

Simultaneous Client and Server Form Validation using Custom Tag Library

I am developing a custom tag library for validator tags
which are capable of doing client side validation (Javascript)
and server side (Java). My problem is with the development
of a regular expression based validator. Because of differences
in the way Javascript and Java handle regular expressions
i can not use the same regular expression for both types of
validation. Is there any way to convert a valid regular
expression from the java.util.regex format into the Javascript
format or vice versa? My major problems are with the (or, ||)
statements and the user of backslashes.

If you are speaking of RE syntax flavours, they are basically the same(namely perl5 flavour). Any expression that works in JS should work in j.u.regex too.
Though, their usage is quite different.
So, there is no need for convertion of expressions.
But porting the code may be not so trivial.

How do I configure portal desktop to use my own custom tag in template?

I seem to have tried everything. I want to use a custom tag from a jar file on a template JSP. I keep getting error saying tag library not found. I have the tld in the meta-inf of the jar. I tried putting the jar in the desktop classes, the deployed WEB-INF lib directory for portal, in the web-src directory for the portal. I tried configuring the uri in the web.xml for the portal webapp. None of these have worked. Does someone know how to do this? If someone could help out that would be great. I tries the jar from a web application and it worked fine. I just need to get this working with Portal Server.
Thanks,
Frank

Thank you for the reply Alex. We are using the Dynamics AX 2012 R3 ISO for our installation. In the software requirement documentation for Dynamics AX it says that is able to run on Windows Server 2012 R2. I believe the prerequisites for Dynamics AX and
Dynamics CRM are different. We received a response from another forum that you can change the .NET version that Sharepoint 2010 uses through IIS in the application pool, but even after setting it to .NET v2.0, we still receive the error in the Dynamics log
that says it is not compatible with .NET v4.0. So I suppose the question is, where does the Dynamics AX 2012 R3 prerequisite checker look to see which version of .NET Sharepoint is using?
Thanks again for the reply!

Custom Tag with script in attribute.

Hi,
          I use a custom tag in which an attribute is generated dynamicly.But it
          doesn't work.
          Here is the sample:
          <tlt:MyTag MyAttr="<%= "abc"%>" />
          the result is MyTag doesn't work correctly but output <tlt:MyTag
          MyAttr="abc" /> in the browser source file.My server is wls5.1 sp6.
          Can I use this approach?

          That's because the value of MyAttr attribute is included in the same
          quotes as the value of the expression. Change the line to:
          <tlt:MyTag MyAttr='<%= "abc"%>' />
          and it should do the trick.

          Oh, I see. You didn't specify that the page uses the Tag Library which
          is done by
          <%@ taglib uri="/uri_to_your_TLD" prefix="tlt" %>
          Another mistake is that the name of the "MyAttr" attribute begins with
          the uppercase letter, so at the end the page compilation will result
          with an error saying that appropriate attribute won't be found or so.
          Change the name of "MyAttr" to "myAttr" or whatever you like, but it
          must start with the lowercase letter.
          Take a look at JavaServer Pages specification available at
          http://java.sun.com/products/jsp. There you can find loads of answers,
          esp. a chapter about Tag Extenstions.

Custom Tag Problems

Hello Everyone,
I am using iPlanet 4.1 as my web server and am having some problems with using custom tags. I try to access a jsp that uses my custom tags and I get a 500 Internal Server error. Then when I check the web server logs all it has is this one very esoteric message: "[26/Sep/2002:08:35:51] warning ( 8042): Internal error: Failed to get GenericServlet. uri=/BUYS/sep_accts.jsp,SCRIPT_NAME=/BUYS/sep_accts.jsp)" Usually I get this message when I make changes to a servlet and do not restart the web server, but that is not the problem this time.
I am trying to use a very simple tag called SayHelloTag which just prints hello to the browser. I have a foundation tag which extends tag support and then SayHelloTag extends the foundation tag. Then I have it all JARd up and in the classpath like I'm supposed to. If anyone could take a look at my code and tell me if you see anything wrong I would be most appriciative!

Cannot find CFML template for custom tag SELECTDATE

Hi,
I am not a ColdFusion developer and just moved a site from one server to another. That site is developed by someone else not me and I just moved the site to ColdFusion server. Site is working fine except a few pages where I am getting this error:
Cannot find CFML template for custom tag SELECTDATE
I read a little bit about custom tags. These are files that needs to be placed in a certain folder from where ColdFusion reads them.
So that means I will need to ask the developer who developed this site to provide me with this custom tag file, which when I will place in appropriate folder, this page will start working? And without that file I cannot do anything about it?
Thanks

As Dan says, they're just CFM files. Usually one can identify them as follows:
* they're in the same directory as a file calling <cf_somefilename[...]>, wherein there is a somefilename.cfm is the name of the file
* they're in one of the directories set as custom tag directories (in CFAdmin, or Application.cfc)
* they have references to "thistag" or the attributes scope in them (although the latter can produce false positives on Fusebox sites)
By the sounds of it, your issue is - like I said before - you haven't got your custom tag dirs set up in CFAdmin (or in Application.cfc, which I didn't mention before). Investigate that.

Trying to create a custom tag

I want to create a custom tag that has a attribute that ask
for a number. like below...
<cf_makeattributes number="?">
Now say I made that number something like 5
<cf_makeattributesnumber=
"5">
I would like for the tag to take that number and make 5
attributes called "Form" in a array from 1 to 5 like below...
<cfset attributes.form = arraynew(1)>
<cfloop index="i" from="1" to="#attributes.number#">
#attributes.form
</cfloop>
Is it possible to make a tag that ask for a number like 5 and
make 5 attributes and within the same tag assign values to those 5
attributes. for example consider the above.
<cf_makeattributes number="5" attribute1="hi"
attribute2="hello" attribute3="howdy" attribute4="hey"
attribute5="HOWE!">
or say i want to make 2 attributes and assign 2 values to
those attributes
<cf_makeattributes number="2" attribute1="This tag asked
for 2 numbers" attribute2="and therefore gave me the ability to
make 2 attributes">
I also have another question that kinda applies to the
question above.
How does the coldfusion server read the tags. for example
look at below
<cf_makeattributes number="2" attribute1="hello"
attribute2="world">
would the server read it like this...
step 1
<
cf_makeattributes number="2" attribute1="hello"
attribute2="world">
step 2
<cf_makeattributes
number="2" attribute1="hello" attribute2="world">
step 3
makeattributes.CFM (it now goes to the template that holds
the tags scripts)
Or does it first read all thats bold below
<cf_makeattributes
number="2" attribute1="hello" attribute2="world">
then goes to the makeattributes template. Is there away I
can compile my script one step at a time like C# and C++ just to
see the steps
PLUS Do i have to put my custom tag into a specific folder or
can I just put it in the same folder as the document thats calling
the custom tag

> I could either make a bunch of attributes that will grab
all the
> values or I could loop out a array of attributes. Thats
my goal
I was with you until that line. The term attributes is
confusing in this context. I'm not sure if you're talking about
attributes in a generic sense or the custom tag attribute
scope.
> Now here wat im thinking now. What if instead I put the
forms in a list. something like this...
> <cf_Formentry
Forms="#Form.one#,#form.two#,#form.three#">
Do you mean form
fields?
Let's try this from a different angle. Can you give a
concrete example of the desired results using this form?
<form>
<input name="username1" value="Alice">
<input name="username2" value="Bob">
<input name="username3" value="Kyle">
<input name="username4" value="Michelle">
<input name="username5" value="Robert">
</form>

Can anyone help me in running this example.

an uri is not an url,
in your web.xml you should have something like
<taglib>
<taglib-uri>http://yourtaglib/taglib</taglib-uri>
<taglib-location>/WEB-INF/yourtaglibtld</taglib-location>
</taglib>
that uri should be same as in the tld.file and same as in the <%@ taglib tag

Custom Tag issue and then ApplicationID?

Hello,
is there anybody out there who can help me with the following
problem:
I installed ColdFusion 4.5 Server on my Windows XP machine
and wanted to access an already built CF application. When
accessing
the main default page, i got the following error:
"Cannot find CFML template for custom tag
CFA_APPLICATIONINITIALIZE.
ColdFusion attempted looking in the tree of installed custom
tags but
did not find a custom tag with this name. "
I copied the same Administrator settings, code and folders
from the
working production server to my local machine and it just
doesn't seem
to work. (I couldn't find any differences to the working
application)
I tried to fix it by copying the custom tag folder (located
under allaire/spectra/customtags/) to C:\CFusion\CustomTags which
somehow cleared the previous error but gave me the following new
one:
"Error Occurred While Processing Request > Error
Diagnostic Information > This application can't be located by
name. Use ApplicationID instead"
Please, i appreciate any kind of comment on this post (i have
been trying to fix this for the past 3 days!)
Thanks,
bbinto

Spectra requires 4.5.1 or 5.
Run the Spectra install to set up all the correct mappings
and the webtop. Then copy over the custom application. It's been
awhile since I've dug into the folder structure of the webtop, so I
don't have a complete list of steps required for a Spectra app
deployment. So you still have some work ahead of you.
Just make sure you backup your database before the install,
mirror it, or use a new schema for the installation and then switch
over your datasources.
I would recommend an old Spectra book you can probably find
on eBay.

Custom Tag Capitalization Problem..

All,
          OS: Windows 2000
          App Server: Weblogic 6.0 sp 2
          JDK: 1.3 (and tried 1.3.1)
          I have a set of custom tags that run fine when I use them on an app server (such as Enhydra) with JDK 1.2.2, but when I switch to JDK 1.3.x, which weblogic 6.x requires, they suddenly start generating errors with attributes which have capitalized letters in them. For example, in my taglib I have:
          <attribute>
          <name>closeConnection</name>
          <required>false</required>
          <rtexprvalue>true</rtexprvalue>
          </attribute>
          and in the support class I have:
          * Get the value of closeConnection.
          * @return value of closeConnection.
          public boolean getCloseConnection() {
          return closeConnection;
          * Set the value of closeConnection.
          * @param v Value to assign to closeConnection.
          public void setCloseConnection(String v) {
          if(v.toUpperCase().equals("TRUE")){
          this.closeConnection = true;
          } else {
          this.closeConnection = false;
          When I go to the page that this tag is on, I get the following output:
          Parsing of JSP File '/index.jsp' failed:
          /index.jsp(1): Error in using tag library uri='/cwerks' prefix='cwerks': There is no setter method for property 'closeconnection', for Tag class 'net.cwerks.taglib.MyTag'
          probably occurred due to an error in /index.jsp line 1:
          <%@ taglib uri="/cwerks" prefix="cwerks" %>
          Thu Aug 02 19:06:52 PDT 2001
          Note that the 'closeconnection' is all lowercase despite the fact that it is upper case in the tld and in the class itself.
          I came across a similar problem in weblogic 5.1 when I upgraded from JDK 1.2.2 to JDK 1.3. I tried changing the JDK for weblogic 6.0 sp 2 to 1.2.2, but a dll was missing. I also tried switching it to 1.3.1, but that did not help. It seems like introspection may have changed slightly between the two version. I'm shocked, and a bit suspicious, that I haven't seen this problem all over the newsgroups. Anyone else seen this?
          Thank you,

A solution presents itself:
          The problem was NOT with capitalization. Instead, the problem was as
          follows:
          My method was for setting a boolean, but I took a string so that people
          wouldn't have to type:
          <mytags:tag foo="<%=true%>" />
          instead, they could type:
          <mytags:tag foo="true" />
          which would call the setter method with a string "true", which would be then
          converted to a boolean within my class.
          So my setter has this signature:
          public void setFoo(String s)
          and my getter has this signature:
          public boolean getFoo() /* I know this isn't standard, but isFoo doesn't
          sound good to me*/
          I can't tell if it's because JavaBeans changed slightly between jdk 1.2.2
          and 1.3.x, or if Weblogic changed the way that they do things (I suspect the
          latter, since I had things working fine in WL 5.2 w/ jdk 1.2.2 and then
          things broke with WL 5.2 w/ jdk 1.3), but this no longer returns foo as a
          valid property to be set, and since weblogic 6.x relies on JavaBeans,
          instead of straight up introspection, it barfs. (I found this out by using
          jad/emacs, a wicked combination for those who want to poke around in jars).
          Anyway, I hope I can save someone else who has this same, albeit
          specialized, problem a lot of pain by my discovery. Your getters and
          setters better be of the same type with custom tags, or weblogic w/ jdk1.3.x
          is gonna barf when parsing the tld.
          Cheers, and thank God that's behind me,

          The plot grows thicker...
          The tags work fine on Tomcat 3.2.2
          I deploy the example tags that came with wl60 that have more than one
          capital letter in thier attributes, and they work fine. But my tag library
          stubbornly insists on not working so long as I keep the attributes with more
          than one capital letter in. If I remove the offending attributes, or change
          them to have only one capital letter, they work, but this is not an
          acceptable solution. (I guess.)
          I even created an simple introspection class to make sure that the acutal
          methods were there. They were.
          I am at a complete loss here... I guess it's tomcat for now.

There are a number possible reasons for the error "runtime failure in custom tag
'process'" for WLCS 3.11 and 3.2. You might check the following:
1) Make sure that WebLogic Server 5.10 SP6 is installed correctly and that
weblogic510sp6.jar and weblogic510sp6boot.jar are at the fronts of
weblogic_classpath and java_classpath, respectively.
2) Check to see if weblogic-tags-510.jar from WebLogic Server 5.10 SP6 is copied
to %weblogic_home%\lib\weblogic-tags-510.jar.
3) The WLPS database is corrupted for reason or another. Rerun the appropriate
database script at \weblogiccommerce\db\cloudscape\create-all-cloudscape.bat or
\weblogiccommerce\db\oracle\create-all-oracle.sql.
