Problem creating custom tag

I tried to create a simple custom tag using apache webserver. my jsp file is HelloWorld.jsp (for presentation, codes listed below), my HelloWorld.java class (listed below) ,a and my TLD file is called WoaTagLibDesc (also listed below). I ran this and I got this error message below:

Your class (according to what is posted) is in the package mytag.
So in your tld: <tagclass>tag.Hello</tagclass>should be<tagclass>mytag.Hello</tagclass>cheers,

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.

Sub components problem in custom tag

Hi!
Im writing custom tag that do nothing but can contains other components.
So first I create custom tag with hendler that extends UIComponentTag and component class that extends UIComponentBase
now tag work but i dont see sub components on the page
Second i override encodeChildren and getFamily methods with:
public String getFamily() {
        return "MyCaller";
public void encodeChildren(FacesContext context) throws IOException {
        Iterator ch=this.getChildren().iterator();
        while(ch.hasNext()){
             UIComponent oKid = (UIComponent)ch.next();
             if(oKid.isRendered()){
                oKid.encodeBegin(context);
                oKid.encodeChildren(context);
                oKid.encodeEnd(context);
        super.encodeChildren(context);
    }But subcomponents not rendered on page.
So are you know whats wrong

the problem was in wrong getComponentType() that return wrong value

Problem with custom tag attribute types

Hi,
I try to figure out how to pass an attribute to a custom tag that is of a type other than "String"?
In my case, I should pass an attribute with a type of "java.util.ResourceBundle".
My tag looks like this:
<tt:cs sel="ab" ce="<%= java.util.ResourceBundle.getBundle("de", Application.getApp().getLocale())%>" />
I always get the message that the attribute ce is empty.
Isn't it possible to have attirbutes that are of an other type than string? How could I solve this problem?
Thanks a lot!
Regards Patrick

In JSP 1.2, in the Tag Library Descriptor, you can specify a tagt attribute as
<attribute>
   <name>attr1</name>
   <required>true|false|yes|no</required>
   <rtexprvalue>true|false|yes|no</rtexprvalue>
   <type>fully-qualified_type</type>
</attribute> Notice the XML element <type>fully-qualified_type</type>
Not sure if you can do this in JSP 1.1

Creating Custom tags

}

Can't say I know much about property editors and even less about BEA
but, a few things
1 Your string comparisions in the IsColumn() method need to use .equals() rather than ==
2 You might consider adding 'get' methods to your Tag. The Property editor would probably like them :-)
3 To print out something from your tag you want the line:
try {
pageContext.getOut().println("RATING is " + rating + " colour is " + dataColor );
pageContext.getOut().println(dataColor);
catch (IOException e) {
throw new JspException(e);
}You should probably be putting your tag class in a package. Java classes without packages can potentially cause problems further down the line.

Jsp:include problem in custom tag

I call <jsp:include page="emailbody.jsp" /> within a custom tag(in a file
          caller.jsp), which does emailing.
          When I invoke caller.jsp from browser, I do get the output(body of the
          email) on the browser screen, but not the output is not send as the body of
          the email.
          When I use static include namely, <@include file="emailbody.jsp" />, the
          output is directed to the body of the email.
          The above means, for a static jsp include file, it is parsed and included in
          the body-evaluation of the custom tag.
          For a dynamic include file, it is NOT parsed and NOT included in the
          body-evaluation of the custome tag.
          The reason could be, How Weblogic loads classes for custom-tag for dynamic
          include files.
          Can anybody at BEA throw loght on this and the solution.
          Thanks in advance.
          Chandra


Well I found out jsp:include is not supported inside custom tags for JSP
          spec 1.1.
          This was stated in section 5.4.5 of spec 1.1.
          May be in future spec 1.2.
          Thanks

Problem with custom tag

I have written a custom tag that I am having problems with. It works on some machines, but not on others. I have a page that uses many 'standard' tags. I have correctly set the URI etc, because all of my other tags work. However, on some machines, my custom tag gives me an error:
attribute does not support request time values
I'm assuming that I have the correct versions of standard.jar etc because all of the regular jstl 1.1 tags work. It is just my custom tag that throws an error.
here is the .tld for my tag:
<?xml version="1.0" encoding="ISO-8859-1" ?>

</taglib>
Any thoughts/help greatly appreciated...

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.

Problems with custom tags (Tomcat 4.1)

I have been trying to set up an existing web application to use a custom tag library. I have these tag-related files:

I have tried many ideas, such as packaging the tag handler class, and putting the class file in other loctions, but nothing has helped.
I know that Tomcat is recognizing PhotoListTag at some point (when it parses the TLD file, but not when compiling the JSP, I think), because if i change the <tag-class> to an invalid class, i get an "Unable to load class photoList" (which is a confusing error message btw, as photoList is not a class, but a tag name).
Does anyone know how to fix this problem? I've been going in circles for hours, and i'm thinking this problem has a simple solution.

Thank you for your quick replies. Unfortunately, they do not solve my problem. If I put PhotoListTag in the com.yourdomain package (and move it to classes/com/yourdomain), the error changes to reflect the different package (e.g. package com.yourdomain does not exist). Also, deleting the class files and restarting Tomcat did not cause any changes.
Although my knowledge of how Tomcat works is limited, it seems to me that something like this is happening:
When a request for /photodb/photolist.jsp is recieved, tomcat processes that file, processes the tld file, and checks for that any classes called using a tag--in this case <photodb:photoList>--exist. If the class is invalid, the error message "Unable to load class photoList" is given.
Otherwise, it translates the jsp into java, and attempts to compile it. This is where the problem occurs. It seems that the jasper compiler does not know where to look for the PhotoListTag class. Is there a way that this can be changed, or is could the problem be caused by something else?

Trying to create custom tag library

I'm a novice trying to create a simple custom tag library application. As such I need a couple import statements like
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext;
This statements will not compile. I'm using Java 2 1.4_03 and WSDP 1.3. My CLASSPATH currently holds
c:\jwsdp\common\lib\servlet-api.jar
and
c:\j2sdk\lib\mysql-connector-java-3.0.11-stable-bin.jar.
I've got JAVA_HOME set to c:\j2sdk and JWSDP_HOME set to c:\jwsdp.
Thank you very much for any assistance you are able to render.

Thanks for your reply. I'm using the TextPad editor, which uses CLASSPATH.
I've figured out the answer. I needed to add
c:\jwsdp\common\lib\jsp-api.jar
to my CLASSPATH.
Again, thanks.

How to create custom tags in my own folder..(It is very important to know)

Hi developers,
I am try to develop custom tags, But i am fail. I take support of internet. I read some documentations to develop custom tags. I can understand everything to develop custom tags . My problem is where to place taghandler,tld and jsp files in tomcat. Could you please guide me how develop custom tags in tomcat. I try to wax. Please guide me.
Thanking you.
with regards
sure...:)-

You'll have something like
tomcat/webapps/mysite
where 'mysite' is the webapp root.
Then
mysite/* - holds JSP (in root directory or any subdirectory except WEB-INF)
mysite/WEB-INF - holds TLDs
mysite/WEB-INF/classes - holds non-jar class files
mysite/WEB-INF/lib - holds the jar file containing the custom tag java code
You can put java classes in either WEB-INF/classes (for *.class files) or WEB-INF/lib (for *.jar files), doesn't matter which.

Problem using custom tag library in portlet's jsp

Hi,
I created a custom portlet (a JSR 168 portlet) and I'm using a tag library that I previously developed. Normally it works fine, but sometimes I get a ClassCastException. Once I redeploy the portlet everything works again. This is Oracle Portal 10.1.4.
Has anybody encountered similar problems?
Here's the exception:

WebCenter Spaces Extensions - Problems creating custom header

Hi,
I'm looking for a way of branding the WebCenter Spaces application so that (among others) I can place my own html fragment above the Primary Tab to render a header and hide out-of-the-box global tool bar, secondary tabs and and the side bar. As far as I understood from the "Extending WebCenter Spaces" document (Link: [http://www.oracle.com/technology/products/webcenter/pdf/owcs_r11_extend_spaces_wp.pdf]) I should be able to do this by creating my own custom shell.
I have taken the gsDefault shell provided within the extendwebcenterspaces.zip file and I got to remove the unwanted bars. Unfortunately I could not get to add my own html fragment for the header. What I have done for this purpose is to change this piece of code in the shell-config.xml:
<shellContent id="gsDefault" displayName="#{uib_o_w_w_r_WebCenter.LABEL_SPACE_MAXIMIZED_CHROME}"
pageTemplate="/oracle/webcenter/webcenterapp/view/templates/WebCenterAppShellTemplate.jspx">
with this one:
<shellContent id="gsDefault" displayName="#{uib_o_w_w_r_WebCenter.LABEL_SPACE_MAXIMIZED_CHROME}"
pageTemplate="*/custom*/oracle/webcenter/webcenterapp/view/templates/*Custom*WebCenterAppShellTemplate.jspx">
For making my custom JSPX file I have taken the default one and made the following change:
Where there was:
<f:facet name="top">
<wcshell:panel name="PrimaryTabBar">
<af:region id="wc_prm"
value="#{bindings.shell_PrimaryTabBar.regionModel}"/>
</wcshell:panel>
</f:facet>
I have placed the following code:
<f:facet name="top">
<af:panelStretchLayout id="pt_psl1">

<f:facet name="top">
<af:image source="/ExtendWebCenterSpaces-StaticFiles-context-root/images/Header.jpg"
shortDesc="BB 360 Header"
id="pt_i1"/>
</f:facet>
<f:facet name="center">
<wcshell:panel name="PrimaryTabBar">
<af:region id="wc_prm"
value="#{bindings.shell_PrimaryTabBar.regionModel}"/>
</wcshell:panel>
</f:facet>
</af:panelStretchLayout>
</f:facet>
I have followed the steps indicated in the document for deploying the custom extensions several times (including, adding the extra java parameter, redeploying and restarting). I know the jspx is accessible as when I try to get it directly from a browser I get a response instead of the page not found page.
Is this the rightway fo doing it? Am I missing something? Which steps could I follow to identify the underlying problem?
Thank you very much.

Marcos,
I am trying to create new site template and getting below error for wcshell:panel.
"No grammer available for namespace http://xmlns.oracle.com/webcenter/shell, content of element panel cannot be validated"
Do you know which JSP Tag Libraries i need to add?
Thanks

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.

Problems Creating Custom Skin w/ further functionality

Hello,
To add that final piece to my project i have been attempting to modify the controls within the flash files located in the program files. I have been successful in editing the look without any problems, but that isn't the end of my plan. I have been attempting to create a "full screen mode" button for my captivate project. As of now i have a button widget that i have created with the appropriate code to make this happen. But i am having some problems it doesn't fit our layout very well. So to fix this i'm wanting to add an additional button into the theme template swf. After looking through the files though i'm unable to locate AS3 class features that show functionality. Or any linkage to point me in an appropriate direction to make my changes/addition. If any of you have any experience in this or if there is just no way to add this feature without an extensive amount of work. Any information would help.
I am using Adobe Captivate 5 as well as Flash CS5, if there's any more info you need i will gladly provide it.
Thank you
