Tomcat4: Illegal to flush within a custom tag
I tried to deploy to Tomcat4.1.18 a jsp-struts application developed with JDeveloper 9.0.3.1, simply obtained using the "Complete Struts-Based JSP Application" Wizard.
When I access to a page containing the
"jbo:DataRecord" tag or the "jbo:DataTable" I get this exception in the error log file (I do not know if other tags give this same error, but for example "jbo:DataScroller" does not):

Deploying on a standalone OC4J everything works.
Is there some configuration to add to the web.xml file or somewhere else? I tried also on Tomcat 4.0.3 with same results.
I added this lines in web.xml to avoid the problems descripted in thread BC4J entity objects vs EJB2.0 entity beans
<init-param>
<param-name>enablePooling</param-name>
<param-value>false</param-value>
</init-param>
Other non-struts-based webapps developed with JDev 9.0.2 and 9.0.3 were deployed correctly on Tomcat 4.1.18.
Thanks,
Marco.
Hi Steve,
I looked better at my page and it has been modified from that produced by the wizard. In fact, the problem arises substituting a DataTable tag with a RowsetIterate in which I put a DataRecord.
Here there is a simple page which produces this error (I see the error only in the error log of Tomcat localhost_log.txt, not on the page):
<%@ page language="java" import="oracle.jbo.*" errorPage="errorpage.jsp" contentType="text/html;charset=windows-1252" %>
<%@ taglib uri="/webapp/DataTags.tld" prefix="jbo" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<html>
<head>
<META NAME="GENERATOR" CONTENT="Oracle JDeveloper">
<LINK REL=STYLESHEET TYPE="text/css" HREF="bc4j.css">
<TITLE><bean:message key="browse.title"/></TITLE>
</head>
<body>
<jbo:DataTransaction appid="Test3Module" />
<h3><bean:message key="browse.header" arg0="CategoryView1"/></h3>
<table border="0">
<tr>
<td ALIGN="right"><jbo:DataScroller datasource="Test3Module.CategoryView1"/></td>
</tr>
<tr>
<%-- REPLACED DataTable WITH a RowsetIterate in which I put a DataRecord --%>
<jbo:RowsetIterate datasource="Test3Module.CategoryView1" userange="true" >
<td>
<jbo:DataRecord datasource="Test3Module.CategoryView1" />
</td>
</jbo:RowsetIterate>
<%--
<td><jbo:DataTable datasource="Test3Module.CategoryView1" edittarget="/edit_CategoryView1.do"/></td>
--%>
</tr>
</table>
</body>
</html>
In this case, it is not so hard to avoid to put in the pages such a code.
Thanks,
Marco.

I'm using this with JSF so it may be different for you:

WebLogic Server 7.0: Including another JSP from within a custom tag
Hi all,
has anyone made experience with including (ie. processing) a dynamic
resource (JSP) from within a custom JSP tag?
Using the following code inside doEndTag():
pageContext.include("/templates/blub.jsp");
throws a ServletException (Note: the JSP is a part of the web app
which is deployed as war). Does it make a difference if the web
application is warred up into and therefore include cannot resolve the
specified relative URL?
[Tomcat 4.1.10 doesn't have problems for that matter]
The full stack trace is:

Try the same code from an exploded web app.

New to JSTL: jsp variable translated literally within the custom tag
I have a basic custom tag that simply processes greeting. Neither of the below scenarios works and I am trying to understand why
<%
String name = (String)request.getParameter( "name" )
%>
<custom:greeting name="<%= name %>"/>
<%
pageContext.setAttribute( "name", name );
%>
<custom:greeting name="${name}"/>
If you have any suggestions, I look forward to hearing from you.When i ran the code I get my "Hello <%= name %> "or "Hello ${name} "
My source
public class HelloTag extends TagSupport{
public String name = "World";
public void setName( String value )
name = value;
public int doEndTag()
try{
pageContext.getOut().println( "Hello " + name );
}catch( IOException e){}
public HelloTag()
super();
What do you mean by jsp level. It resides in my Root directory under Tomcat -
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.quote:

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. -
Dynamic include in a custom tag, called from a jsp
Hello, I would like to be able to dynamically include other jsp's from within a custom tag that I create. is this possible?
in a jsp page i would just write <%@ include file="file.jsp" %> and all would be ok... but if i do an out.println( "<%@ include file=\"file.jsp\" %>" ); inside a custom tag bean then it doesn't work. it just prints out the command to the page as plain text.
I do understand why this is happening, but can anyone offer me a way around this problem?
Thanks in advance,
RandyThat's actually the same result as you get with a normal include - The method I suggested is a dynamic include similar to the <jsp:include> tag, not the <%@ include %> tag.
When you use a dynamic include, the included page is compiled and 'invoked' as serarately, and the result is what gets included, not the actual source. To get the behaviour you want would require an include directive (the <%@ include %> tag) which I don't think has an equivalence you can use inside a custom tag.
What you can do is pass attributes from the tag class like this:
pageContext.setAttribute(<name>, <object>, pageContext.REQUEST_SCOPE);
and then remove them after the include using pageContext.removeAttribute.
I'm not certain, but this implies that if you declare your variables with a <jsp:usebean> tag with request scope, instead of normal Java variable declarations, you should be able to use them in the page included by the custom tag.
*** in the jsp ***
<jsp:useBean id="myVar" scope="request" class="java.lang.String" />
<% myVar = "Something"; %>
// Now call the tag which uses the pageContext.include() mehtod.
*** end ***
*** in the include ***
<jsp:useBean id="myVar" scope="request" class="java.lang.String" />
<%= myVar + " something else" %>
*** end ***
Let me know if it works. -
Custom Tag Error with Weblogic SP9
Hi
I seem to be having a problem with a custom tag that I wrote. When I run the JSP
on WLS (without a service pack), the generated java code uses the weblogic.utils.StringUtils
class to interprete jsp expressions that are passed into the custom tag's attribute
(on the JSP). The method called on this StringUtils class is valueOf(). This method
in essence makes sure that the result of the expression is not null and then subsequently
calls a toString() on the value. Note that if the value is null it simply returns
an empty string.
The problem is that when we go to service pack 9, this method is not called (StringUtils.valueOf()).
Now the problem arises if first of all the result of the expression statement
in the custom tag definintion (on the JSP) is null. Secondly, it will also error
out when the setter method is called within the custom tag, if the object returned
from the expression does not match the one that is expected by the tag... in our
case a String.
Here's a sample usage of the tag:
<wescombop:selectTag
selectName="buildingNumber"
selectedItem="<%= buildingJB.getBuildingNumber()%>"
trimSelectedItem="true"
selectTagDataName="buildingNumberDataAttribute" />
Note: buildingJB.getBuildingNumber() returns BigDecimal
Here's a snipett of the line generated java:
* Without the service pack
comwestfieldgrp_wescom_bop_view_tag_SelectTag_1.setSelectedItem(weblogic.utils.StringUtils.valueOf(buildingJB.getBuildingNumber()));
*With Service Pack 9
comwestfieldgrp_wescom_bop_view_tag_SelectTag_1.setSelectedItem(buildingJB.getBuildingNumber());
Note: The setSelectedItem() method expects a String object as a parameter, so
the code with service pack 9 will result in a compilation error, since buildingJB.getBuildingNumber()
returns a BigDecimal.
Let me know if you need more explanation.
Has anyone experience this problem before... Any help would be deeply appreciated.
Thanks all.

Parsing EL expression in custom tag 10.1.3.4
Hello all,
I have a custom tag that extends CoreOutputTextTag. This tag needs to resolve the El expression passed in from the value attribute and perform an operation with it. Since I this tag needs to work with adf 10.1.3.4, the jsp level is 1.2 and does not support container parsing of EL expression directly in the page ($).
I have tried a couple approaches but both of them result in just the same EL expression I pass in being returned to me. Anyone have an idea of the proper way to resolve an EL expression within a custom tag?
Thanks in advance,

Custom tag library called multiple times
Hi ppl ,
I have a custom tag library which i use to populate some menu components. When i do call my custom tag library though , it is called multiple times, use case is as follows.
I have menu tabs and menu bars which thanks to Mr.Brenden is working splendidly as so:-
<af:menuTabs>
<af:forEach var="menuTab" items="#{bindings.menu.vwUserMenuTabRenderer.rangeSet}">
<af:commandMenuItem text="#{menuTab.MenuLabel}"
shortDesc="#{menuTab.MenuHint}"
rendered="true"
immediate="true"
selected="#{sessionScope.selectedMenuId == menuTab.MenuId }"
onclick="fnSetSelectedValue('#{menuTab.MenuId}')" >
</af:commandMenuItem>
</af:forEach>
</af:menuTabs>
<af:menuBar>
<af:forEach var="menuBar" items="#{bindings.menu.vwUserMenuBarRenderer.rangeSet}">
<af:commandMenuItem onclick="return clickreturnvalue()"
onmouseover="dropdownmenu(this, event,#{menuBar.MenuId}, '150px')"
onmouseout="delayhidemenu()"
text="#{menuBar.MenuLabel}"
action="#{menuBar.MenuUri}"
rendered="#{menuBar.ParentId == sessionScope.selectedMenuId}"
immediate="true" />
</af:forEach>
</af:menuBar>
</afc:cache>
now all of this code is within a subview , and just directly below the subview tag , i have the call to my custom tag library:-
<myCustomTagLib:menuCascade />
only issue now is that assuming i have in all 7 menu bar components, the doStartTag is called 7 times. the relevant code within my custom tag class is as follows :-
public int doStartTag() throws JspException {
return (EVAL_BODY_INCLUDE);
public int doEndTag() throws JspException {
try {
declareVariables();
return EVAL_PAGE;
}catch (Exception ioe) {
throw new JspException(ioe.getMessage());
and within my declareVariables method i do an out of the jscript ( out.print(jscript.toString()); ) which is a simple string generated based on certain conditions...
now it seems to be working fine on the front end , but when i view the source of the page, i notice that the declaration is called multiple times, and this happens because the doStartTag method is called multiple times, i haven't even nested the call to the custom tag within the menu components , any clue as to whats going wrong ?
Cheers
KHi,
if you add the following print statement
System.out.println("rendering "+FacesContext.getCurrentInstance().getViewRoot().getViewId());
Then the output in my case is
07/04/24 08:14:04 rendering /BrowsePage.jsp
07/04/24 08:14:05 rendering /otn_logo_small.gif
The image comes from the file system, which means it is rendered by the JSF lifecycle. If you reference the image with a URL then the lifecycle doesn't render the image but only refrences it.
To avoid your prepare render code to be executed multiple times, just check for jsp and jspx file extensions, which will guarantee that your code only executes for JSF pages, not for loaded files.
The reason why this happens is because the JSF filter is set to /faces , which means all files that are loaded through that path

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

IOException when flush is called from a custom tag
Thanks is advance for the help. I've encountered an oddity in OC4J 10.1.3 Standalone using java 1.5 the 2.4 servlet spec and struts 1.1 and I'm wondering how to resolve it. In our current application we use custom tags to define certain fields. Every tag in our web front end does the same thing.
<pre>
JspWriter writer = pageContext.getOut();
writer.print(sb.toString());
writer.flush();
</pre>
I would understand if the tag was calling a commit then flush and then trying to write to the buffer again. That should raise this exception. We have tags that do the same thing without issue, But some others fail. This is the stack trace we see in the logs.
<pre>
WARN - SpecialReviewTag.doStartTag() IOException:
java.io.IOException: InValid to flush BodyContent: no backing stream behind it
at com.evermind.server.http.EvermindBodyContent.flush(EvermindBodyContent.java:213)

at javax.servlet.http.HttpServlet.service(HttpServlet.java:856)
</pre>
Here is where the oddity comes into play. The page still renders all the needed information for the user. The problem lies with this exception being flooded into our production logs.
This is the web.xml file being used to define our .jsp configuration
<pre>
<jsp-property-group>
<display-name>Ignore EL</display-name>
<url-pattern>*.jsp</url-pattern>
<el-ignored>true</el-ignored>
<scripting-invalid>false</scripting-invalid>
<is-xml>false</is-xml>
</jsp-property-group>
</pre>
One other not these tags worked fine in the OC4J 10.1.2 Container this happened after the conversion to OC4J 10.1.3
Thanks alot for the help,
Charles
Edited by: CharMow on Feb 11, 2009 5:14 AMHi,
I am also getting the same error, when we move to OC4J 10.1.3.
If you find any solution for this please let me know, Thanks in advance.

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. -
