Setting up custom tags using Cfmodule?

I have just set a site up on Godaddy, on a shared CF server, so I don't have access to the administrator to set up a custom tag
I believe it's possibly to set up a tag by uploading into my web root and then referring to it using CFMODULE
Can anybody offer any help on this as I can't get it working.
the issue is I want to set up DLL custom tags, such as CFX_ZIP (CFX_ZIP), and CFX_GIFSIZE (gifsize.dll)
Thanks
Mark

I guess I could try some createobject code to see if it works on godaddy
Would you be able to post some example code?
Sure. Here is a simple test. If by some miracle that actually runs without error, you can find a .NET example in the documentation
<cfset str = createObject("java", "java.lang.String").init("Test this")>
<cfoutput>#str#</cfoutput>
Also, find out what version of CF you are using. If it is CF8+ you are in business.
<cfoutput>
version #server.coldFUsion.ProductVersion#
</cfoutput>

Custom Tag using object as an attribute.

I have read up on trying to pass an object as an attribute to a custom tag.
Is it true that the only way to do this is to put the object, using a "key name" in the pageContext
Then in the custom tag, set an attribute equal to the "Key Name"
Then in the TagHandler, to do a lookup using the "Key Name"
We can not just past objects into the attribute?
And what is this about using EL or JSP2.0
sorry sort of new to the whole game.

Certainly you can pass objects to tags.
However you need to use a runtime expression to do that.
such as <%= expr %> or (with JSP2.0) ${expr}
If you look at the JSTL library, it uses the EL and passes in objects all the time. However the EL actually accesses the page/request etc attributes as its variable space, so you are still technically using attributes.
Is it true that the only way to do this is to put the object, using a "key name" in the pageContext
then in the custom tag, set an attribute equal to the "Key Name"
then in the TagHandler, to do a lookup using the "Key Name"That is one way of doing it. The struts libraries use this method extensively. It is more suited to JSP1.2.
Sometimes it is easier/neater just to put the value into a scoped attribute, and pass in the name of that attribute. That way you don't need to worrry about the type of the attribute at all in your JSP.
Hope this helps some,

Is it possible to set a custom tag attribute from a TagExtraInfo?

Hi Everyone,
I'm developing my own tags and I need to set some optional attributes of my custom tag if the user doesn't do it.
Is is possible to do that on the IsValid method of a TagExtraInfo class?
The code is running without exceptions but is not setting the attribute.
My Tag (The optionValue attribute is optional):
<qe:select name="cars" optionBody="carName" optionValue="carID" />My TagExtraInfo class:
public class SelectTei extends TagExtraInfo {
    private static final Logger logger = Logger.getLogger(SelectTei.class);
    @Override
    public boolean isValid(TagData tagData) {
        String optionBody = tagData.getAttributeString("optionBody");
        String optionValue = tagData.getAttributeString("optionValue");
        if (optionBody != null && optionValue==null){
                tagData.setAttribute("optionValue",optionBody);
        //Other validations....
        return true;
}

It's not obvious as to how to set a background color which is by default, black.
Assuming you mean set the background color of a new image, just set the desired canvas color using hex or a named color ie "red", "white", ...

Custom Tags Using Facelets

I am trying to simplify a lot of pages by using Facelets and custom taglibs that are just .xhtml pages with other Standard JSF components inside them. My problem is not really related to that, but it gives a bit of background info: What I am trying to do is simplify the naming of binding and value attributes by trying to concatenate Strings to form a reference to a managed bean/property.
I am trying to do something like this:
<c:set var="componentVal" value="'#{formBinding}.#{formName}.#{componentName}'" />
<c:set var="componentBind" value="'#{beanBinding}.#{formName}.#{componentName}'" />
<h:inputText id="#{id}" value="#{componentVal}" binding="#{componentBind}" size="#{size}" />This comes after iterations of trying to just concatenate the bound variables (formBinding, formName, and componentName are defined earlier). Is this possible in JSF or am I barking up the wrong tree? I am trying to use this solution because we have one session-bound managed bean with different components for different tabs on the screen, and are accessed via a map, which makes the names quite long, and they only give us 17" monitors here, so, aside from making it cleaner, I will actually get to see what I am doing without scrolling all over the place.
Thanks for any and all help/advice.

i am trying to use:

But noway to figure how to set this value.

Problem with custom tag using TagExtraInfo

          Hi,
          I have a tag that create a Java variable using TEI. The scope of this
          variable is driving me crazy. The problem is hard to describe, so the
          email is a bit long - stay with me...
          <pre:setvar id="foo" value="test" /> create a Java variable
          named "foo", which has String value "test". I can use "foo" like this in
          the page later: <%= foo %>.
          Now, if I call setvar twice with same id:
          <pre:setvar id="foo" value="test" />
          <pre:setvar id="foo" value="another-test" />
          This is still ok. By checking the compiled Java file, the first call
          declare the var, the second call just use it without creating it again:
               //first call
               String foo=null;
               foo="test";
               //second call
               foo="another test";
          Now the problem comes when the frist call is in "if" statement (code is not
          useful, only for demostration):
          <% if (1>0) { %>
               <pre:setvar id="foo" value="test" />
          <% } %>
          <pre:setvar id="foo" value="another-test" />
          The compiled code looks like:
               if (1>0) {
                    //first call
                    String foo=null;
                    foo="test";
               //second call
               foo="another test";
          Variable foo is out of scope at the second call! (BTW, I can workaround this by
          adding another <pre:setvar id="foo" value="" /> before the "if".)
          Is it a fault in JSP specification? Or a problem when WebLogic implements TEI?
          Any idea?
          Thanks,
          -- Jin


I encountered the same problem in our environment. I did the same thing as
          James. Simply re-initialize all variables in the do end tag.
          Also, with the nested tags you use you may also need to implement cloneable
          in the inner tag if the outer tag keeps references to all the inner tag
          instances.
          For instance if the outer tag kept a vector of references to the inner tag,
          then you would need to use clone() on the inner tag before adding it to the
          vector.

Custom tag using viewobject

Hi all
Im developing a JSP 1.2 tag lib for our production enviroment to save us alot of repetitive code, therefore i decided to make a table component that can do sorting on header and would like to write the sorting code directly in the doStartTag on the library but my issues is the following:
I send ${bindings.testData1.rangeSet} as an attribute on the table tag, this translates into a "oracle.jbo.uicli.binding.JUCtrlRangeBinding$1" (note the $1 at the end) in the actual code, my issue is that i need it to be "oracle.jbo.uicli.binding.JUCtrlRangeBinding" in order to typecast it. But unfortunatly i cant typecast it since the $1 is most likely the local implements and not the actual class...
I might be approaching the issues incorrectly and should try and get something out of the pagecontext as well, but since i allready have the variable it seems to be the easiest to just get the actual collection and sort it instead of having to go through the applicationmodule etc.
All ideas are very welcome, hope the question makes sense :)
Edited by: Jesper Lind on 16-Feb-2009 05:11

Hi Frank
Well the thing is that the rangeset is a colletion so can get the iterator from that, but the thing is i would like to get the view object it belongs to so i can do sorting, but by the looks of it i have to do some java reflection to get the enclosingclass out or something similar.
in the jsp it looks like the following:
<sometag:table items="${bindings.testData1.rangeSet}"...
Then in the java class "items" is read as a collection and then the iterator from the collection is used to create a loop.
What i would like to do is something like e.g pseudo code.
JUCtrlRangeBinding b = (JUCtrlRangeBinding)collection.getEnclosingClass();
b.getViewObject().setSortBy("some column");

How can I use evaluate to get the instance variable in customized tag

1.
At first , I create a class called bean,and declared several params in it and do not define any getter function for the param.
class bean{
String param = "test";
SomeClass scObj = new SomeClass();
2.
The second ,I use
request.setAttribute("beanObj",new bean());
3.
And then I wanna use the customized tag to show a text box , then initialize it's value.
<salt:text name="param" value="beanObj.param">
<salt:text name="obj" value="beanObj.scObj.func()">
4.
I tried the evaluator provided by JexlContext ,Struts, JSTL and it seems that if I do not define the getter for the variable ,I can not get the bean's instance variable's value.
Expression e = ExpressionFactory.createExpression( value );
JexlContext jc = JexlHelper.createContext();
jc.getVars().put(strInitBeanName, request.getAttribute("beanObj"));
Object obj = e.evaluate(jc);
the result of the obj is null....
Can anybody recommand some other evaluator can get the value of a instance variable from an object?

do you have any other suggestion ? Nops, somebody else may have though. AFAIK, all lookups of the type
beanName.propertyNameuse reflection on the getXXX() methods to access the property.
Having said that, I guess you could write one though in a custom tag, using the same - reflection (you will ahve to rely on the java.lang.reflect.Field class quite heavily) - but that would be reinventing the wheel for most other functionality that you would have to include (like looking up the bean in scope etc)

Using JSTL tag in a custom tag

Hello,

Not in tag classes. Possible if you implement custom tags using [url http://www.onjava.com/pub/a/onjava/2004/05/12/jsp2part4.html]tag files

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.

          /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?

How do you reference a custom tag?

I just wrote a set of custom tags (for the first time). I have a strange problem:
I need to call some tag methods while inside of the tag like this:
          <JSP:SearchResult id="result">
               <%= (result.getResultNumber()+" "+result.getResultField("summary") %>
          </JSP:SearchResult>The problem comes when i execute this code, i get this error:
org.apache.jasper.JasperException: /result.jsp(21,2) Unable to find setter method for attribute: id
any sugestions?
Here is the relevant part of my TDL:
<tag>
     <name>SearchResult</name>
     <tagclass>com.bsci.app.searchengine.SearchResultTag</tagclass>
     <bodycontent>tagdependent</bodycontent>
     <info>
          returns seach results
     </info>
     <attribute>
          <name>id</name>
          <required>true</required>
          <rtexprvalue>true</rtexprvalue>
     </attribute>
     </tag>

You are right.
Maybe this is a good time to leave work.
One last question then.
It seems like i cant exectute the following code no matter what value i use in the TDL in each tag's <bodycontent> fields.
setting bodycontent to JSP does not work for simpleTags, and this isnt scriptless/empty either.
It seems to me like the only correct solution would be to write to "stdout" in the java code of the tags, but that limits me in what i would like to output which is a bummer.
<JSP:SearchContainer indexDir="C:/temp2" query="<%= query %>" startPage="0" resultsPerPage="5">
     <JSP:SearchHeader id="header">
          <%= header.header %>
     </JSP:SearchHeader>
     <JSP:SearchResult id="result">
          <%= (result.getResultNumber()+" "+result.getResultField("summary") %>
     </JSP:SearchResult>
     <JSP:SearchFooter id="footer">
          <%= header.nextPage %>
     </JSP:SearchFooter>
</JSP:SearchContainer>

Dynamic include inside custom tag body

I am trying to perform the dynamic include of another JSP from within the body of a custom tag using JSP1.1. It cannot be done using <jsp:include> since flush=true is required and thus an exception is thrown when called from inside the body of a custom tag - it can be done in JSP1.2 since flush does not have to be set to true but upgrading is not possible at this time.
Does anyone know of any custom tag or the code needed to perform this function with JSP1.1?
I am using Tomcat 3.2.3.
Using a RequestDispatcher and calling include() does not have the desired effect since the output is witten directly to the response and does not go into the correct position in the calling JSP.
I think the solution involves making a call to the included JSP (is it possible to use a RequestDispatcher that doesn't write directly to the page output stream?) and then append the response to the BodyContent object which is buffering the body content of the custom tag until the doAfterBody() method is called. Is it possible to create a dummy ServletResponse object to pass to the RequestDispatcher and then obtain the HTML response from the internal buffer?

I don't know if there is a solution to the problem you are having with JSP 1.1. If you look in the spec, it actually warns you that dynamic includes can not be done inside a body tag. The spec actually states that the included code shout write directly to the response and not to the BodyContent.
I was excited to find out they had fixed this in JSP 1.2, but they seem to have foiled me again. If my tag calls PageContext.include(), the spec says that include must call the flush method, which causes BodyContent to throw an exception since flush is not a valid call.

Problem creating custom tags for site that has no outside internet connecti

I've created a set of custom tags that work fine until we install our app at the customer site. The customer site has no outside Internet access, and so the DOCTYPE is failing since it references the web-jsptaglibrary_1_1.dtd located on Sun's site.
I tried copying the dtd locally and got it to work, but the solution sucks because this web-jsptaglibrary_1_1.dtd file is referenced in both my taglib.tld file AND the web-jsptaglibrary_1_1.dtd itself. Soooo....I can put in a URL that references it on the local machine, e.g.,
In the taglib.tld file:
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.// DTD JSP Tag Library 1.1//EN"
"http://ClientAAA/web-jsptaglibrary_1_1.dtd">
In the web-jsptaglibrary_1_1.dtd file:
<!ATTLIST taglib id ID #IMPLIED
xmlns CDATA #FIXED
"http://ClientAAA/AdProduction/web-jsptaglibrary_1_1.dtd"
>
but that means for every client that uses this app (and we have several) I have to change that URL inside both these files.
I tried simply changing it to the relative "web-jsptaglibrary_1_1.dtd", e.g.,
taglib.tld:
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.// DTD JSP Tag Library 1.1//EN"
"web-jsptaglibrary_1_1.dtd">
web-jsptaglibrary_1_1.dtd:
<!ATTLIST taglib id ID #IMPLIED
xmlns CDATA #FIXED
"web-jsptaglibrary_1_1.dtd"
>
but then it is requiring me to put the dtd in both my web app root directory AND my jakarta/bin directory. I get the following error:
XML parsing error on file ../vtaglib.tld: java.io.FileNotFoundException: D:\jakarta\jakarta-tomcat-4.1.29\bin\web-jsptaglibrary_1_1.dtd (The system cannot find the file specified)
It seems like I must be missing something here. This shouldn't be this hard. And it seems funny that to use custom tags, you have to have Internet access in the first place.
Help!!! :)
Thanks.

Yeah, I think it's a bit ridiculous that in order to make all the tag library examples and instructions work, you have to have access to the Internet. I haven't seen a single example on how to make it work if there is no Internet access. That's very limiting. And I've tried all sorts of other ways of doing it, such as
<!DOCTYPE taglib SYSTEM "web-jsptaglibrary_1_1.dtd">
but even then it won't work because I get an error message saying:
XML parsing error on file /assets/../vtaglib.tld: java.io.FileNotFoundException: D:\jakarta\jakarta-tomcat-4.1.29\bin\web-jsptaglibrary_1_1.dtd (The system cannot find the file specified)
I just don't think I should have to place this file in the bin directory. There has to be another way. Do I need to modify the dtd somehow? Cuz the dtd has the following line...is this messing it up??
<!ATTLIST taglib id ID #IMPLIED xmlns CDATA #FIXED "web-jsptaglibrary_1_1.dtd">
I sure could use some help.

Problem Calling Query in Custom Tag

I am using this code to call a custom tag called
broadcast.cfm
<cf_broadcast query="fe" orgID = "4">
The query fe is an included file on my site and is available
to the page I'm calling the custom tag from.
In the custom tag I am referencing the query like:
<cfloop query="#attributes.query#">
but I keep getting this error:
"The value of the attribute query, which is currently "fe",
is invalid. "
I must be missing something really simple here but can't
figure out what.

It is a scoping problem. The query is defined in the calling
page. To access it by name, within the custom tag, use the "caller"
scope.
<cfloop query="caller.#attributes.nameOfTheQuery#">
If the query object is passed to the custom tag via an
attribute you shouldn't need the caller scope. See attached sample.
