Using Javascript attributes in a JSP-Tag

Hi!
I want to submit a Javascript attribute to an embedded jsp Tag:
<script language="JavaScript">
function test()
var jscriptvar= document.myform.myselection.selectedIndex;
result = <%= jspobj.doit(jscriptvar) %>;
</script>
The exception is : Undefined variable: jscriptvar
Is that possible?
It works, if the doit-method doesn't have a parameter.
I hope, someone can help me.
Thanks

JavaScript is executed on the client-side by the browser. The JSP code is executed on the server-side by the server and has no knowledge of JavaScript variables. You can not mix them in this manner.

Class as an attribute name in JSP tag file

I just ran into an issue where I was writing a custom tag to generate a specific set of HTML elements, and wanted to be able to use CSS the same way I had before refactoring it into a tag. So, I included 'class' as an attribute in the custom tag file and deployed.
On Glassfish v3, this generated a bunch of JasperExceptions in the Javac compilation, complaining about <identifier> expected and reaching the end of file while parsing. I tracked it down, of course, to the use of 'class' as an attribute name, which was reduced to a servlet class defining:
public String getClass() {
return this.class;
public void setClass(String class) {
this.class = class;
}I'm curious -- which part of the process messed up here? Is "class" a valid identifier under the Java EE spec, and the translation should have used something like setClass_(String class_)? Or is it invalid, and Netbeans didn't know to mark it as an error before it tried to deploy? (And, of course, that I missed that in the spec, making it my fault.) I couldn't find anything specifically saying that reserved words couldn't be used as JSTL identifiers, so my gut is that the parser messed up. Also, I found a bug report about it for an alternate web container, but no mention of it in the bug trackers for Glassfish, Tomcat or Jasper.
Where's the blame?

I think that Netbeans messed up. getClass() is, of course, defined on Object and class is a Java keyword.What's to stop the compiler from recognizing that "class" would be a problem and mapping it to an alternate name behind the scenes?
This is the only documentation I turned up. Maybe this says it's invalid:
Java EE SpecThe unique name of the attribute being declared. A translation error results if more than one attribute directive appears in the same translation unit with the same name.A translation error results if the value of a name attribute of an attribute directive is equal to the value of the dynamic-attributes attribute of a tag directive or the value of a name-given attribute of a variable directive.

How to use javascript functions in struts jsp page

Using Bean Attributes in a JSP for a h:commandLink

Hi,
I am very new to JSF so apologies if the answer is obvious.
I currently have a ArrayList of products obtained from a database.
Using...
<h:dataTable value="#{ProductBean.productList}" var="product">
                <h:column>
                    <f:facet name="header" >
                        <h:outputText value="Title"/>
                    </f:facet>
                    <h:outputText value="#{product.title}"/>
                    <f:facet name="header" >
                        <h:outputText value="Picture"/>
                    </f:facet>
                    <h:outputText value="#{product.picture_url}"/>
                </h:column>
            </h:dataTable>The contents of the ArrayList are printed out fine.
I am now looking to iterate over the items to output a link
so far I have... but it doesn't seem to work
<c:forEach items="${ProductBean.productList}">
                    <h:form>
                    <h:commandLink action=images/"#{productList.picture_url}" title="#{productList.title}"><h:graphicImage url="thumbs/#{productList.picture_url}" width="100" height="75" alt="" /></h:commandLink>
                </h:form>
                </div>
            </c:forEach>I think the problem lies with appending the "images/" before the url
Ideally I would like it to replicate the actual HTML view which is
<a href="images/london_flight.jpg" title="London in Flight"><img src="images/london_flight.jpg" width="100" height="75" alt="" /></a>If anyone could shed any light it would be much appreciated.
Thanks in advance

Thanks that was helpful so I have modified my code to...
            <c:forEach items="${ProductBean.productList}" var="product">
                <div class="thumbnail">
                    <h:form>
                    <h:commandLink action="images/#{product.picture_url}" title="#{product.title}"><h:graphicImage url="thumbs/#{product.picture_url}" width="100" height="75" alt="" /></h:commandLink>
                </h:form>
                </div>
            </c:forEach>But I seem to be getting a jsp error...
javax.el.ELException: Not a Valid Method Expression: images/#{product.picture_url}
How can I append "images/" to the action without it falling over.
Thanks

Using jsp variables within JSP tag

I have a variable defined within a JSP:
<%
String cust_id = request.getParameter("cust_id");
%>
I want to use this variable as a parameter to a custom tag:
<%@ taglib uri="/tlds/DBTags.tld" prefix="db" %>
<db:MultiColumnSelect columns="c.id, c.po" name="ccar_id" table_name="ccar_headers c, ccar_rmas r" selectString="r.ccar_id = c.id AND c.cust_id = <%= cust_id %>"/>
The selectString value that is passed to my tag is:
r.ccar_id = c.id AND c.cust_id = <%= cust_id %>
The <%= cust_id %> is not replaced by the actual variable value.
How would I accomplish using this variable within my JSP tag?

Your definition of the selectString attribute must indicate that it can accept runtime expressions.
<%
String cust_id = request.getParameter("cust_id");
String selectString = new String("r.ccar_id = c.id AND c.cust_id = " + cust_id);
%>
<%@ taglib uri="/tlds/DBTags.tld" prefix="db" %>
<db:MultiColumnSelect columns="c.id, c.po" name="ccar_id" table_name="ccar_headers c, ccar_rmas r"
selectString="<%= selectString %>"/>

How to use JavaScript in Web bean generated JSP

I want to do some simple JavaScript validations (for example, checking if a particular field is empty) in the JSP page rendered by the data web bean. Because the HTML is rendered by the bean, I'm not able to refer to the HTML controls in the JSP page. I'm not even able to refer to the form with the following standard piece of JavaScript code - "document.forms[0].control_name".
Is anybody aware of how to use JavaScript with these rendered JSP pages?

You just have to add it like and applet , including this line in your JSP or JSF
<script src="http://dl.javafx.com/dtfx.js"></script>Then add the applet
<script>
    javafx(
              archive: "./resources/jar/Draw.jar",
              width: 400,
              height: 200,
              code: "Draw",
              name: "Draw"
</script>./resources/jar/Draw.jar - is the path and the name of the jar

Using gateway'd URLs in JSP custom tag attributes

Hello,
I am running Plumtree G6 using a gateway prefix to gateway Javascript from a remote server. I have recently discovered, thanks to people's help on the forum here, that in certain cases, you need to wrap a URL in a pt:url tag in order for Plumtree to recognize it as a URL that has to be gateway'd (i.e. a URL inside of a Javascript function).
However, I have a custom tag that contains a contextPath attribute. This custom tag then includes other XML files that get included in the final page that is displayed. I am passing this value as my contextPath:
<mytag:body sessionName="mysession" campusName="SampleCampus" contextPath="<pt:url pt:href='http://localhost:7021/application/scripts' xmlns:pt='http://www.plumtree.com/xmlschemas/ptui/'/>"/>
However, in the resulting content that is created from this custom tag, the contextPath value is still set to <pt:url pt:href=......./>, and not the actual gateway'd URL. I would have thought that Plumtree would have recognized and gateway'd this URL before it got substituted in the custom tag.
Does anyone have any thoughts on how to get around a problem like this? One thought I had was to get ahold of the gateway URL value and pass that value directly in my contextPath attribute. Is it possible to get that gateway value, or is there a better solution here?
Thanks again for any help you can provide.

Chris,
I added your code, changed the portlet's web service to send a login token for this portlet, and was then getting some ClassNotFoundExceptions related to Axis classes. So, I went and added all of the jar files from the devkit's lib directory (i.e. plumtree\ptedk\5.3\devkit\WEB-INF\lib), recompiled, and those errors went away. But, now I see the following error:

Using scriplets in jsp-tag attribute

I have a strange problem with a custom taglibrary that I'm trying to write.
When I use the tag in a jsp like underneath the first outputs the right value (Welcome Hans), but the output of the second time shows: Welcome <%= test %>
This is a part of the JSP:
<% String test = "Hans"; %>
<arto:hello name="Hans" />
<arto:hello name="<%= test %>" />
I realy don't know how to let the tag display the value of the string in my jsp.
Can anyone give me some advice?
Thanks,
Hans
The files are:
import java.io.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
public class HelloTag extends TagSupport {
private String name;
public void setName(String name) {
this.name = name;
public int doStartTag() throws JspException {
try {
pageContext.getOut().print("Welcome " +name);
} catch (IOException ioe) {
throw new JspException("Error: IOException while writing to client");
return SKIP_BODY;
public int doEndTag() throws JspException {
return SKIP_PAGE;
The JSP:
<%@ taglib uri="arto" prefix="arto" %>
<%
String test = "Hans";
%>
<arto:hello name="<%= test %>" />
<arto:hello name="Hans" />
The TLD:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">

<info>Tag with Parameter</info>
<attribute>
<name>name</name>
<required>false</required>
<rtexprvalue>false</rtexprvalue>
</attribute>
</tag>
</taglib>

In the tld for the name attribute, use
<rtexprvalue>true</rtexprvalue>
This specifies that the attribute value can be a run-time expression. Otherwise, the value is taken as a literal.

In javascript how to use jsp tag value

i want to change td value while clicking the options.In the td contains jsp page.while clicking the options i want to load particular jsp within in the td.i change the td value using innerHTML by assigning value this format <jsp:include page="..."/>.It's gives some error .
JspTranslate:Attribute has no value
code:
function rightPageload(strPage) {
pageval='<jsp:include page="/jsp/library/"'+strPage+'"/>'
document.getElementById("d1").innerHTML=pageval;
}

Do you want to use taglibs or develop custom tags? Either way take a look at these:

Spec oversight? Using dynamic-attributes in XML tag files

I have a couple of tagfiles that generate form elements with specific conventions for the 'name' and 'value' attribute. Basically, a data binding framework.
Dynamic attributes are useful because you can delegate all the usual html attributes to the generated HTML form element: SELECT, INPUT, id, class etc.
The usual way to do this is to concatenate all the "pass-through" attributes to a string, and append this string to the element generated:
<input type="hidden" name="foo" ${dynattrs}/>I'm wondering how to do this in a tagfile in XML format (mytag.tagx), since the XML format forbids syntax like in the example above.
jsp:attribute won't help much, if it's nested inside a c:forEach: it won't apply to the right element.

Ran into the same problem with 'optional attributes'. (see post "JSP 2.0 Tag files outputting elements with conditional attributes" http://forum.java.sun.com/thread.jspa?forumID=45&threadID=681033)
Found a solution that is not very elegant but does work and saves you the trouble of reverting to Java Tags. Consider the following tag-file that outputs an html input-tag with conditional attributes:
<?xml version="1.0" encoding="utf-8"?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="1.2"
     xmlns:c="http://java.sun.com/jsp/jstl/core">
     <jsp:directive.attribute name="name" required="true" type="java.lang.String"/>
     <jsp:directive.attribute name="id" required="false" type="java.lang.String"/>
     <jsp:directive.attribute name="value" required="false" type="java.lang.String"/>
     <jsp:directive.attribute name="disabled" required="false" type="java.lang.Boolean"/>
     <jsp:directive.attribute name="hint" required="false" type="java.lang.String"/>
     <jsp:directive.attribute name="cssClass" required="false" type="java.lang.String"/>
     <jsp:text><![CDATA[<input type="text" name="]]><c:out value="${name}"/><![CDATA["]]></jsp:text>
     <c:if test="${!empty id}"><![CDATA[ id="]]><c:out value="${id}"/><![CDATA["]]></c:if>
     <c:if test="${!empty cssClass}"><![CDATA[ class="]]><c:out value="${disabled?(cssClass + '-disabled'):cssClass}"/><![CDATA["]]></c:if>
     <c:if test="${disabled}"><![CDATA[ disabled="disabled"]]></c:if>
     <c:choose>
          <c:when test="${!empty value}"><![CDATA[ value="]]><c:out value="${value}"/><![CDATA["]]></c:when>
          <c:when test="${!empty hint}"><![CDATA[ value="]]><c:out value="${hint}"/><![CDATA[" onfocus="if(this.value==']]><c:out value="${hint}"/><![CDATA[')this.value='';"]]></c:when>
     </c:choose>
     <jsp:text><![CDATA[/>]]></jsp:text>
</jsp:root>In answer to your question: Yes, it looks like an oversight. Using the jsp:attribute tag in a c:forEach doesn't work because the attribute is then applied to the forEach tag. You would have to put the attribute-tag inside a jsp:body tag (inside the forEach). Then it would apply not to the forEach tag but to the tag enclosing the forEach. However, this doesn't work either, or at least it doesn't work in Tomcat 5.5. Could be a bug though, JSP 2.0 is still very buggy (for instance, using a tagfile inside another tagfile from the same taglib doesn't seem to work either...)
Anyway, if you ever find a good solution please let me know by posting to this topic!
TIA

Problem with boolean attribute of JSP tag

Hi,
I've being trying to use a custom JSP tag, which has a boolean attribute, declared in the TLD as follows:
<attribute>
<name>checked</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
<type>boolean</type>
</attribute>
The JSP code snippet is:
<ui:check checked="<%= myBean.isChecked() %>"/>
where myBean.isChecked() returns a boolean value (primitive type).
It works fine on some web containers, but it causes a JSP compilation error on Oracle9iAS 9.0.3 Java Edition, which looks like the following:
Method toBoolean(boolean) not found in class test. _jsp_taghandler_57.setChecked( OracleJspRuntime.toBooleanObject( toBoolean( myBean.isChecked())));
After decompiling the container's JSP parser, I found what I think it's a bug. The java class generated by the JSP parser does not define a toBoolean method, and neither do its superclasses. The method is defined on the OracleJspRuntime class! I think the correct code would have to be something like:
OracleJspRuntime.toBooleanObject(OracleJspRuntime.toBoolean(...))
If I'm correct, then the "convertExpression" method of the "oracle.jsp.parse.JspUtils" class must be changed, because it outputs such wrong code for not just boolean types, but for all the primitive types.
So, has anyone ever faced this problem before? Does it have a workaround, or a patch? Is it included on the bug fixes for the 9.0.4 release?
Thanks!

Instead of:
out.println("<body onload ="+strAlert+">");
Try this:
out.println("<body onload =\""+strAlert+\"">");
Add two \" around the alert call.
