[Tomcat bug?] Calling response.sendError(404) from JSP

Calling "response.sendError(404);" from JSP context causes Tomcat to mangle all non-latin characters.
Any ideas why?
How to recreate bug:

    <error-page>
        <error-code>404</error-code>
        <location>/404.jsp</location>
    </error-page>
</web-app>Calling of index.jsp should cause 404 error with custom error page. The error page is utf-8 encoded and contains russian characters. That's by design.
In fact, Tomcat shows ?????? instead Russian variant of "Hello".
Tomcat/5.5.17 or Tomcat/5.0.28.- it does not matter.
Is it Tomcat bug or I should not call response.sendError(404) from JSP?

it's not a tomcat bug, it's rather a problem with
your code.
change index.jsp like the following then test
it !
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01
Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<%@page pageEncoding="utf-8"%>
<%@page contentType="text/html; charset=utf-8"%>
<%
esponse.sendRedirect("blablablablablabla.html");
%>
<html>
</html>
Thanks for the insight. But the issue here is with the response.sendError() method.

<html>
<head>
<title>Script Example</title>
</head>
<body>
<br><br>
<P align="center">
<form action="" method="post">
<script language="JavaScript">
function comEventOccured()
try{
var myobject;
myobject = new ActiveXObject("LPMSFunctions72.LPFunctions72");
alert("Inside LPMSFunction72");
alert(myobject.GetDocPath());
catch(e)
alert("Error");
</script>
</form>
</body>
</html>When i write the above code and save it as an html file it works fine..the activex object is created and the methods are called , but when i copy the same code to a file and save it as jsp file under webapps folder under tomcat it doesnt work and reports a javascript error with the error being:
Automation server cant create the object at line :
var SSOObj = new ActiveXObject("LPMSFunctions72.LPFunctions72");
Please suggest how can I solve the problem. Your help would be sincerely appreciated.

You want to use the Variant to Data node, wiring in an ActiveX constant configured to the interface type you want.

Call a Perl Script from JSP

Hi guys,
I am developing an online ticket booking system.
i have come toa point where i need to call a perl script from JSP.
please let me know how to do it.
Basically, i need to call a function in perl script from JSP in order to encrypt my information.
Any help is appreciated.
Thanks in advance.
Chintan Shah

I haven't done this myself, but it seems like it is possible in Tomcat.
You can configure Tomcat to handle .cgi calls (it does this via a CGI servlet)
http://www.ftponline.com/javapro/2003_03/online/perl_teden_03_18_03/
http://tomcat.apache.org/tomcat-5.0-doc/cgi-howto.html
Once this is set up, theoretically you should be able to then use requestdispatcher and forward/include a cgi script to invoke the perl.
I don't know if you are using Tomcat or not though... :-)

Calling custom OAF page from JSP page in Oracle apps

Hi,
I am working on a requirement to call a Custom OAF page from a JSP page in Oracle apps 11.5.10.
I have registered the OAF page and defined a function for it. When we call this OAF page from JSP (without parameter), the page opens up
URL: http://APPSURL:8020/OA_HTML/RF.jsp?function_id=27221&resp_id=50312&resp_appl_id=515&security_group_id=0&lang_code=US
but as soon as I am trying to pass a parameter sr_id in the URL:
http://APPSURL:8020/OA_HTML/RF.jsp?function_id=27221&resp_id=50312&resp_appl_id=515&security_group_id=0&lang_code=US&sr_id=106
we are getting following error:
You are trying to access a page that is no longer active.
- The referring page may have come from a previous session. Please select Home to proceed.
Please let me know if someone has faced the same problem...
Thanks!!!

Hi,
Before calling a OAF page..from external JSP page...u need to set certain mandatory parameter like transaction Id and context.

3. Create a connection class in write a code here and you should have host, port and userid/password of the ECC system from where you are calling your RFC.
4. After making a connection then write a code to pass import parameters and execute.
5. After execution of RFC you will get export parameter, table or structure.
6. Display this data now as a respose.

Calling my Java class from JSP page

Hello, I am trying to call my Java class from my JSP page passing parameters to it and getting back a collection of result sets. Can someone tell me what I might be doing wrong:
JSP code to call Java class:
<%
String strEssUser = "test";
String strProcessingMonth = "JUL";
String strProcessingYear = "2002";
strQueryList=new ListReturn(strEssUser.toString(), strProcessingMonth.toString(), strProcessingYear.toString());
%>
I get this error when I try to run this JSP page using tomcat:
C:\Program Files\Apache Tomcat 4.0\work\Standalone\localhost\em\jsp\Test_0005fSummarySBU_0005fscreen$jsp.java:77: Class org.apache.jsp.ListReturn not found.
strQueryList=new ListReturn(strEssUser.toString(), strProcessingMonth.toString(), strProcessingYear.toString());
I'm not sure if this problem is the way I am calling the Java class, or if I have a problem in the Java code itself. Can anyone help?

Ok, I get a very strange error now:
org.apache.jasper.JasperException: Unable to compile class for JSPerror: An error has occurred in the compiler; please file a bug report (http://java.sun.com/cgi-bin/bugreport.cgi).
What is this??? Anyone?

Call pl/sql API from jsp portlets

HI ALL!

thx
Alizeh

Hi
thanks for ur reply but where were u a month ago,i really started to think that my question was enough stupid not to be answered.At present i have done with jdbc and pl/sql calls ,current concern is for sessions as i see that session id remains same when one user logs out and another logs in(if browser is not closed), same sessionid persists in my java portlet for both users.Is this an expected behaviour?? but yes new session id appears if browser is closed.
.session clear for both application and sso after logout is checked
.broser is set to check for new version each visit for the page
portal version is 3.0.9.8.0 ,we r planning patch to 3.0.9.8.3 soon
once again thx

How to call java class file from jsp

hi
we need to call java classes (which are written separately in .java file )from jsp file. we need it for our project if anyone knows about please reply us.
bye
siva sankari

you can call the methods in a lot of ways. you could use scriptlets with the
<%@ page import="package.class"%> and then inside instantiate an object
<%
MyClass mc = new MyClass(parameters if any);
mc.theMethodYouWantToCall();
%>or as Madathil has stated,
or use the JSP tags
<jsp:useBean id="anyname" class="classname"/>and then use the getProperty tag
or even Custom Tags

How to call an ejb method from jsp?

How to call custom Login Module from JSP

Hi,
I am stuck with the following issue:
1) Exactly as presented in help.sap.com (http://help.sap.com/saphelp_nw04/helpdata/en/3f/1be040e136742ae10000000a155106/content.htm) I created custom login module and deployed it as a library on J2EE server. When I configured it to be used for my applications in the Security provider but I am getting "No user name provided" exception everytime when my applications use this custom login module.
2) I realized that I would need to call my custom module somewhere within my application (simple JSP) using LoginContext class and then use MyLoginContext.login() spec to initiate login process. But I am not able to pass CallbackHandler parameters from JSP application to my custom login module.
So I have the following questions:
1. Can I pass parameters using LoginContext and CallbackHandler from JSP to my custom login module (created as exact copy of HELP.SAP.COM example) or this module cannot be used this way.
2. How to pass CallbackHandler correctly to my custom login module from JSP. When I am trying to use CallbackHandler, I am getting "Abstract Class cannot be called" error.
I'd appreciate any little help on this matter.
Thanks and regards,
Mike

You have two alternatives to do this:
You can declare your JSP as a protected resource with the use of the deployment descriptors of the application (web.xml) and add the custom login module in the authentication stack of the application. This way, you will use container-based authentication, i.e. the Web Container will enforce the authentication and it will call the custom login module before it dispatches to the JSP. I recommend you this approach because it requires less coding and it makes the whole thing a matter of configuration. The configuration can be later on enhanced or changed runtime without the need to re-build and re-deploy the application. If you choose this approach you can go to the documentation of the server for help on how to modify the login module stack of the application.
You can also use programmatic authentication by using JAAS API. To do this you need to create a custom security policy configuration with login module stack containing the custom login module, and then use the standard JAAS mechanism - new LoginContext(<configuration>, <callback-handler>).login(). This approach requires that you write your own callback handler and handle any LoginException.
Let us know which approach you prefer and whether you have difficulties implementing it!

Call Crystal Report 8 from JSP?

There is not any direct support, but you can use INet Crystal Clear API. It comes with an Applet client, and you can use that applet client from jsp to display crystal reports.

Call to BPEL Process from JSP - Not working!

Hi All,
I'm trying to execute the sample JSP page provided in the BPEL Guide, which calls the BPEL "CreditRatingService" service.
The JSP Page compiled normally, but it does not invoke the BPEL Process. The JSP Page is just waiting.. the browser is loading the page for ever..which means it is not able to call the BPEL process. If i comment the below code
NormalizedMessage res = deliveryService.request("CreditRatingService", "process", nm);
then the page is displaying..
Thanks for any help

Hi Afonso,
I looked at the files under the below locations..
C:\product\10.1.3.1\OracleAS_1\j2ee\home\log\home_default_group_1
C:\product\10.1.3.1\OracleAS_1\bpel\system\logs
C:\product\10.1.3.1\OracleAS_1\bpel\domains\default\logs
I found the below error mesage
<ERROR> <collaxa> <ProcessJob::execute> Timed out reading http:.........
from C:\product\10.1.3.1\OracleAS_1\bpel\system\logs\orabpel.txt log file.
But this log file is generated when I start my SOA Suite and not when I open the JSP Page. But I'm guessing may be for the same reason, it the not calling the BPEL process.
I don't have any issues while I deploy the BPEL process or calling the BPEL Process from the console.
Thanks for any help
-Chandra

Tomcat 6 Calling a Java Servlet from a JSP Page
