Thread waits in huge JSP EL pages

I am trying to understand the behaviour of the weblogic JSP runtime when a large JSP page with lots of JSP EL expressions is requested concurrently by a number of users
Tomcat caches the evaluated EL expressions and there is a bug in the ExpressionEvaluator which can cause a lot of threads to wait on a synchronized method. we are trying to do the same test on weblogic and we found this in the thread dumps st highly concurrent loads (100+ concurrent requests)
Our env:
WL 9.2 on Fedora Core 5 x86/BEA JRockit(R) R26.0.0-189_CR269406-59389-1.5.0_04-20060322-1126-linux-ia32

I looked at this posting:
http://forums.bea.com/bea/message.jspa?messageID=600017709&tstart=0
with 9.2, is the behaviour as mentioned in CR261427 patch ? is weblogic now caching the evaluated expressions and is it now thread-safe
we noticed a dramatic slowdown in the response times (from 1 sec at low loads to 6-8 seconds at 200+ users)..of c ourse with smaller JSP pages (with less EL expressions) the slowdown is not that dramatic and weblogic scales well...
Any pointers appreciated,
Ravi

java.lang.reflect.Array is NOT a class which represents an array.
It is a class that provides several static methods for using on arrays.
The type of your attribute should be Object[] - an array of Objects.
That will be compatible with an array of any sort of object (but not with an int[] for instance)
<%@ attribute name="list" required="true" type="java.lang.Object[]" %>

JSP error page does not displayed on its own, includes in the original JSP

Problem Description: - Exceptions in a Condition cause pages to fail to render.
The actual issue is, the JSP error page does not displayed on its own, included in the original JSP Page when exception occurs.
Problem Cause: As per the JSP specification when jsp content reached the buffer size (default 8KB) the page being flushed (Part of condent displays). The default �autoFlush� value is true.
When the page buffer value is default size (8KB), and if any exception occurs after flushing the part of the content, instead of redirecting into error page, the error page content included in the original page.
If i specify autoFlush="false" and with default buffer size, at the runtime if the buffer size is reached, i am getting stackoverflow error.
To solve the above problem we can make it autoFlush=�false� and buffer=�100KB�. But we can�t predict the actual size of the page.
I found in one of the weblogic forum as no solution for this issue. Ref.
http://support.bea.com/application?namespace=askbea&origin=ask_bea_answer.jsp&event=link.view_answer_page_clfydoc&answerpage=solution&page=wls/S-10309.htm
Please provide me any solution to resolve the problem.

Error-Page tags work best with an error.html pages. If you have an error.jsp page what I would do, and I have, is wrap my classes and jsp pages in a try catch block where you forward to the error jsp page and display anything you want. YOu can also do this with if else statements. I have used the tomcat error pages before but when I've implemented them I used java.lang.Exception as the error to catch not Throwable. I don't know if this would make a difference or have anything to do with your problem.

How to make the main() thread wait?

I would like to know how to make the main() thread wait for another thread?If I use wait() method in main() method it says "non-static method wait() cannot be referenced from a static context",since main()
is static.

Here is an example how you may wait for a Thread in the main -
but be careful, this is no real OO:
public class WaitMain {
// this is the thread class - you may also create
// a runnable - I use a inner class to
// keep my example simple
     public static class ThreadWait extends Thread{
          public void doSomething(){
               synchronized(syncObject){
                    System.out.println("Do Something");
                    syncObject.notify();
          public void run(){
               // sleep 10 seconds - this is
               // a placeholder to do something in the thread
               try{
                    sleep(10000);
                    doSomething();
                    sleep(10000);
               catch(InterruptedException exc){
// this is the object we wait for -
// it is just a synchronizer, nothing else
     private static Object syncObject = new Object();
     public static void main(String[] args) {
          System.out.println("This will start a thread and wait for \"doSomething\"");
          ThreadWait t= new ThreadWait();
          t.start();
          synchronized(syncObject){
               try{
// this will wait for the notify
                    syncObject.wait();
                    System.out.println("The doSomething is now over!");
               catch(InterruptedException exc){
          // do your stuff

Using JSF in jsp segment page..

Hello
Is it possible to use JSF components in a JSP segment page(.jspf) ? I couldn't achive that..Let me explain:
I created a .jspf file and inserted these lines into it:
<f:view>
    <h:form id="loginform">
        <h:panelGrid columns="2">
            <h:outputLabel value="User:"/><h:inputText id="username_email"/>
            <h:outputLabel value="Password:"/><h:inputText id="password"/>
        </h:panelGrid>
    </h:form>
</f:view>after that i included this .jspf file to a jsp file. When I run the application,I get this error:

        <h:panelGrid columns="2">
            <h:outputLabel value="User:"/><h:inputText id="username_email"/>
            <h:outputLabel value="Pass:"/><h:inputText id="password"/>
        </h:panelGrid>
    </h:form>
</f:subview>
logincontrol.jspf (2)
<f:view>
    <h:form id="loginform">
        <h:panelGrid columns="2">
            <h:outputLabel value="User:"/><h:inputText id="username_email"/>
            <h:outputLabel value="Pass:"/><h:inputText id="password"/>
        </h:panelGrid>
    </h:form>
</f:view>but nothing changes... i added this line, in the .jsp file:
<%@ include file="WEB-INF/jspf/logincontrol.jspf" %>   by the way, is it good to write a .jspf file for login process and include it to the pages?

Which jar file is required for jsp dynpro page programming ?

Hi all:
I use NWDS wizard to create one small jsp dynpro page application. However the project has some errors, it said "
This compilation unit indirectly references the missing type com.sapportals.htmlb.page.DynPage (typically some required class file is referencing a type outside the classpath) Test1.java NewParProject1/src.core/com/xinao/test line 0
" However, I found the class DynPage is not found in current project.
I have already added com.sap.portal.htmlb_api.jar into my project.
Where can I locate and find that jar file (which include the DynPage class ) ?

Hi,

Waiting for another JSP to end.

document.dados.action = "exists.jsp?familia="+familia;
document.dados.submit();
alert('After ');the problem is that when I execute this peace of code the exists.jsp runs AFTER
alert('After '); this one...
But I wanted to do that alert before this...
I belive the question is: how can I wait in my jsp for another jsp to finish running?
Can you help me?
Thanks in advance.

Here is a link with the monthly fees:

You would be forced to select one of these plans and pay for the actiavtion as well as the first month up front. With the cheapest plan this will be a little over $100.

Where to mention the IP address in a JSP dyn page

Hi ,
I am creating a mail sending system with Javamail.
Created the JSP dyn page,
wrote the event handler in the java file. and all.
now I have to mention the IP address of the SMTP server.
where should I do this....
inside the event handler itself?
Thanks in advance.

Hi
The button tag in the jsp looks like this
<hbj:button
        id="sendEmail"
        text="sendEmail"
        width="125px"
        tooltip="Click here to send mail"
        onClick="sendEmail"
        disabled="false"
        design="STANDARD"
        />
The function to handle the button eventing occurs in the dynpage . The function looks like
public void sendEmail (Event event) { ..coding.. }
Now when the button is clicked, the control is transferred to this event handler sendEmail and the code with init starts executed.
Hope it is clear...

Access Java class in my JSP/JSF page and conditionally open a new browser

When the user clicks on a button in my JSP page, I'd like to launch a new browser and display certain things in that browser window while leaving the original browser window open.
My thought was to invoke a javascript method in 'onLoad' which would determine if the new window needs to be launched.
This is kinda what my page looks like:
<jsp:root version="1.2" ................>
    <jsp:directive.page import="java.util.*, com.test.Configuration" contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"/>
    <f:view>
     <ui:body binding="#{Page1.body1}" id="body1" onLoad="launchWindow();">
     </ui:body>
   </f:view>
   <script type="text/javascript">
        function launchWindow(){
         if (Configuration.openWindow()) {
          window.open("hello.jsp", "newWindow", 'toolbar,width=400,height=400');
    </script>
</jsp:root>My problem is that the call to "Configuration.openWindow()" does not resolve correctly. If I remove that call and simply make a call to "window.open()" all works. But once I put the condition in, nothing happens. I do not see an exception in my browser window but a new browser window does not open.
Is my syntax correct. Can I make a call to the static method 'openWindow()' in my class 'Configuration.java'.
thanks,
tsc

I have made some changes so that I do not directly access the 'Configuration' class in my javascript.
I have a hidden field on my form and when the user clicks the button, in my back bean, I set a value for the hidden field. In the javascript function 'launchWindow()' I check if a value has been set for the hidden field and if yes, I open a new window.
<ui:body binding="#{Page1.body1}" id="body1" onLoad="launchWindow(document.forms[0]);">
<h:inputText id="hiddenField" value="#{formBean.hiddenValue}" />
<script type="text/javascript">
        function launchWindow(form){
            alert("in lw");
            var test = form["form1:hiddenField"].value;
            alert("got test");
            if (test != "")
                window.open("hello.jsp", "newWindow", 'toolbar,width=400,height=400');
            alert ("done test");
</script>When my page is first loaded, the launchWindow() is called and all the alerts popup as expected.
When I click on the button (the back bean sets the value on the hidden field), my page is reloaded but this time its blank.
Any ideas as to why this maybe the case?
thanks,
tsc

Jstack shows a thread waiting for monitor entry but it's already acquired

I have a heavy load website powered by tomcat-6.0.14 and jdk1.6.0_02-b05(amd64) on a 2 dual-core amd Opteron. When tomcat started, and I directed the http request(~200/s) abruptly to tomcat, it looks choked for over one minute, and if I took off the http requests, tomcat can recover in a few minutes.
Then I use jstack during the choke time to find what's the cause, where I found a strange situation. Almost all threads are blocking on getting a log4j lock(I think it's normal,since log4j use a coarse lock), but one thread which already got the lock are also blocked. Below is the stack trace.

I'm really wondering why jstack shows the first thread is BLOCKED but no blocker.
And also, it's not a deadlock, since I made jstack log after sever seconds, and found this time another thread has the same problem.

What's the cause? Is jstack accurate? Or, the problem is caused by hotspot compling since tomcat is just started? Or it's just because log4j's coarse lock? ( but after the starup, tomcat can handle the same traffic without any problem, and jstack shows no log4j block at all.)
Thanks in advance.

It seems like a Dead Lock.
The thread must have entered into a synchronized block/method1() and acquired a lock.
- locked <0x00002aaab39d5670> (a org.apache.log4j.spi.RootLogger)
While having lock the thread might be trying to acquire a lock to another synchronized block/method2()

and someother thread might have already acquired a lock to that block/method2().
Can we check for Dead Lock??

Is it possible to use two diff forms in same jsp/jsf page?

Hi all,
My requirement is to submit the form based on selection of radio button.
since half part needs to be jsp based which is not using any tags etc.
But i am trying to use some jsf based component which requires to be inside <f:view><h:form> of
<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core" %>
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html" %>
i.e. some <c:comboBox>
</h:form> </f:view>
Now earlier i was submitting the form as
<form action="/techstacks-v2_1/reportAction.do" method="post" name=doSearch id='doSearch'>
But now i found, in order to use combo box component which is entirely jsf based i need to use <f:view><h:form> which is kind of taking over the previous form submission mechiansm.
I am trying to keep them separate as two differnt forms.
one entirely jsp based and other as jsf based.
Now my question is can i use such way of doing so or is there any better way of implementing so.
My friend suggested that i can pass the value of jsf based form in hidden form to a input box of form to be submitted finally instead of submitteing two diff forms.
but in that case also i ahev to use two forms in a single jsp/jsf page.
suggest me something which can really work out.
thanks

You can use as many forms as you want as long as you don't nest forms. The HTML spec probibits that.

JspParse Error when trying to run jsp/jspx page deployed on standalone OC4J

I have ADF Faces Application, which is developed with JDev 11 TP3.
I have deployed the application to Standalone OC4J Server, packed within JDeveloper 11 TP3.
The problem comes, when i try to acess my login jsp or other JSPX page,then i receive the following error on the standalone OC4J Server console:
for the JSP:
JSP Servlet Error: Internal Error, registered Directive handlers MUST descend from JspDirective
oracle.jsp.parse.JspParseException: /login.jsp : Line 4,
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
The content of my JSP page (login.jsp) is:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<%@ page contentType="text/html;charset=windows-1251"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
for JSPX:
Directive handlers must descend from JSP Directive..
But i have:
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
<jsp:directive.page contentType="text/html;charset=windows-1251"/>
That works fine with JDev embedded OC4J.
Thank you in advance,
Krasimir

Same trouble. Anyone have solution?
JDeveloper 11 TP4
OC4J 11 TP4 from this http://www.oracle.com/technology/tech/java/oc4j/index.html
Do this instruction http://www.oracle.com/technology/products/jdev/tips/muench/oc4j11gtp/index.html

Are you having trouble with tabs in a list?
You haven't said so.
In lists you have to use option tab, otherwise it just changes the list level.

I guess what you were hoping but you missed the point.

Get response message in JSP error page

Hi,
Here's a simple one for someone. I HAVE been searching everywhere for the answer but its one of those things I just cant seem to find.
If I call response.sendError(SC_FORBIDDEN, "Invalid roles"); from a servlet or filter, how can I retrieve the message "Invalid roles" in my JSP error page? (which I have mapped to 403 errors in web.xml).
Its so simple yet I cannot figure out how to do it.
Thanks in advance,
Robert.

I tried but had no luck. Below is my JSPDYNPAGE code...
<%@ page import="javax.servlet.http.HttpServletResponse" %>
<%@ page import="com.sapportals.portal.prt.component.IPortalComponentRequest,com.sapportals.portal.prt.component.IPortalComponentResponse"%>
<HTML>
     <head>
     </head>
     <body>
<%
IPortalComponentRequest request = (IPortalComponentRequest) this.getRequest();
HttpServletResponse servletResponse = request.getServletResponse(true);esss
servletResponse.setStatus(500);
%>
          </body>
     </HTML>
It is not working showing portal run time error

JSP error page in web.xml

I had a JSP error page spcified through the attribute isErrorPage and referenced in the other JSPs through the errorPage attribute, and everything worked well.
Then, I decided to specify that errorpage in the web.xml instead :
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/error.jsp<location>
</error-page>The page is found and everythiing, except that I don't get the Throwable info in the implicit exception object in error.jsp. There's nothing in exception.getMessage().
Anybody knows why and the solution to this ?

The JSP spec lets you get the Throwable through the javax.servlet.jsp.jspException request attribute.
The servlet spec uses the javax.servlet.error.exception request attribute for the same thing.
Therefore, because of the above unfortunate mismatch, when you switched to a global error page, you could no longer get the Throwable through the implicit exception obj, because the later retrieves Throwable from the javax.servlet.jsp.jspException request attribute.
The solution would be to retrieve javax.servlet.error.exception from the request yourself in your error page.
