JSP is executed 2 times

Hello to everybody. I have a problem using the OutputStream of the response object in a jsp. I use the page to show a pdf document that it's created from a method of a bean. The response.getOutputStream is a parameter of the method and it writes the exit in the OutputStream directly.
The code is more or less this:
response.setContentType("application/pdf");
ServletOutputStream sos = response.getOutputStream();
// The OutputStream is sended to the method
consPdf.StringToPdf(stringXml, sos);
sos.flush();
sos.close();
It does well, but the problem is that the page is executed 2 times and the execution time is duplicated. Anyone knows why?
Thanks.

Hi
This is Explorer bug. It detects that data type is PDF and then it reads the PDF again.
One solution is to enable IE cache (set some response headers) so it will cache a PDF.
best regards,

HOw to update XML file residing in DAM by component JSP in run-time?

i have made a component which reads xml file residing in DAM.
Content Author can fill some values in dialog of this component, as soon as author provide the values,i have to update these values in XML file and component reloadsby reading the updated xml file.
i am trying to achieve this by making object of XML file and giving it's path., but i ma unable to access the XML file.
Can anyone help me out to how to update XML file by component JSP in run-time?

Now the changed data must be exported back into the XML file, meaning that the content of certain elements must be updated. How can this be done with XSLT?
XSLT approach: check these online tutorial
http://www.xml.com/pub/a/2000/08/02/xslt/index.html
http://www.xml.com/pub/a/2000/06/07/transforming/index.html
ABAP approach:
for example you have the xml (original) in a string called say xml_out .
data: l_xml type ref to cl_xml_document ,
        node type ref to if_ixml_node .
create object l_xml.
call method l_xml->parse_string
exporting
    stream = xml_out.
node = l_xml->find_node(
    name   = 'IDENTITY'
   ROOT   = ROOT
l_xml->set_attribute(
    name    = 'Name'
    value   = 'Charles'
    node    = node
(the above example reads the element IDENTITY and sets attribute name/value to the same)
like wise you can add new elements starting from IDENTITY using various methods available in class CL_XML_DOCUMENT
so how do I access the XML file in order to update it?
you have already read this XML into a ABAP variable right?
Sorry couldnt understand your whole process, why do you need to read local XML file?

Getting error in JSP at compile time:

Hello,
I am getting this error in JSP at compile time, have no idea whatd going wrong here..!! Everything in the code looks good.
Please help..!! The error is:
Error 500: Unable to compile class for JSP /opt/WebSphere/AppServer/temp/jasi80corpgeNode/HRAppServer/Billinginterface/BillingInterfaceWEB.war/_select_5F_course.java:188: Type expected. } catch (Throwable t) { ^ 1 error

Everything looks good, but then you can never spot your own mistakes :-)
There are a couple of things.
1 - curly brackets in scriptlets. Make sure they are all opened and closed correctly.
2 - Custom tags (JSTL and the like) need to be closed. If it is a simple tag, have you forgotten the slash before the closing angle bracket? ie is it <c:out value="hello"> when it should be <c:out value="hello"/>
Take a look at the generated java code at /opt/WebSphere/AppServer/temp/jasi80corpgeNode/HRAppServer/Billinginterface/BillingInterfaceWEB.war/_select_5F_course.java, line 188
See if you can make any sense out of the java file generated from the jsp
If you want any more specific help than this, please post some jsp code :-)
If you don't want to do that, I would recommend commenting all the code out with <%-- --%>
get it to compile, and then uncomment a bit at a time
Good luck,

JSP for executing scripts

Hi
Is it possible for jsp to execute shell scripts which connects the remote host .
For example if i have a script which first connect to remote host ,fetch data from the host and give result back.
Simply want to know if jsp can execute these shell scripts also or not.
Thanks

I donot think so that my question make less sense .Yes i know that JSP is run on server side .Remote host (to explain you better) means another server.
I have a script which connect another server whenever it is run .The script is running properly when run from command prompt .
JSP page can run shell scripts(which contains simple commands like ls ,ps , so on....) But when this particular shell script which connect another server to get result ,is executed through JSP did not work.
Hope this make sense to you

JSP not executing the java code

Hello there.
my m/c: tru64 unix
Apache version: 2.0
tomcat version: 4.0.5
browser version: IE5
I have index.jsp as
=======
<HTML>
<HEAD>
<TITLE> Vimala's JSP </TITLE>
</HEAD>
<BODY>
Hello <%= request.getParameter ("name") %>
<%
for (int i=1; i < 5; i++)
out.print ("<BR> Sample JSP loop");
%>
<FORM METHOD=POST ACTION="vimala.jsp">
Enter nothing
<INPUT TYPE=TEXTAREA NAME=name>
<BR><BR><INPUT TYPE=SUBMIT>
</FORM>
</BODY>
</HTML>
=======
The above neither prints the getParameter ("name") as passed in URL nor it prints the "for loop" values.
However the html related things such as title and Form are properly displayed in the browser.
I think I'm missing something in the tomcat (server.xml) or apache (httpd.conf) configurations. Your inputs to solve my problem is very much appreciated.
Thank you,
Vimala.

Please find the web.xml here.

JSP NOT EXECUTING

Hello helping hands,
I am having a problem of JSP pages not getting executed. The setup is I have a Webserver and Appserver (Websphere 5.0) on different (unix) machines.
Have JSP page and I have put a log message at the very start of the page (not in a global function though). So ideally every time I execute I should have a log message on my log right ?? This is not the case.
When I monitor the log (by viewing it dynamically -tail command ), only some visits cause the log to be written and not all the visit to the page.
Local WSAD machine the code works fine and everything is ok. I do not have access to the Webserver and Appserver configurations and the group responsible is not able to solve this so far.
Please let me know why this is happening ?
Thanks in advance,
Bharani
PS: The server group is denying any cache setup but I am not sure of their claim. So any specifics ??

I already have
<META http-equiv="Pragma" content="no-cache">
<META http-equiv="Expires" content="-1">
and
response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");
response.setDateHeader("Expires", 0);
response.setHeader("Expires","-1");
response.setHeader("Cache-Control","no-store");
Both at the html level and JSP level expiration. Doesnt help

Local WSAD machine the code works fine and everything is ok. I do not have access to the Webserver and Appserver configurations and the group responsible is not able to solve this so far.
Please let me know why this is happening ?
Thanks in advance,
Bharani

1. Will the URL that i am trying to access be:
http://localhost:8080/examples/jsp/gcdBB/LoginServlet
2. Regarding WEB-INF/classes/gcd/gcd folder (note - 2 times gcd). When LoginServlet.java (located in: WEB-INF/classes/gcd) is compiled in JCreator, a second gcd folder is automatically created (WEB-INF/classes/gcd/gcd).
Should I make any corrections, or alterations?
Thanks,
Niall

Same Servlet/JSP is executing again and again

          Hello,
          We have some JSPs which do a lot of processing and is 'alive' for a long period
          of time. If we use the JSP with small amouts of data, it is fine. But when we
          use the JSP with lot of data, it seems to 'go in a loop'.
          It is processing the data again and again and again and brings down our server.
          We do not think it is the code that is wrong - as it processes perfectly if the
          data is small or when our server is not busy. This problem happens if the data
          is lot and the server is also busy. The JSP seems to be executing again and again.
          Is there some type of 'refresh' logic in weblogic that refreshes the JSP/servlet
          and makes it 'execute' again and again.
          We are using WL 6.1
          Thanks,
          Oleg.


there is no refresh logic in wls unless u specify it.
          please check the code for any "refresh"ing the page

How to show a JSP Page Multiple Times ??

Dear Experts,
Our requirement is like :
The client chooses to enter the details of 10 customers in the First Jsp page , by selecting 10 in a dropdown list and clicks the Proceed button in the same JSP.
The Second JSP ie. Customer Details Jsp is popped up and the client enters the details of the first customer. Then he clicks Next Button in that JSP.
Clicking the Next Button in the Second JSP, will :-
1>Create a customer object to store the details and add the object to an arraylist ,
2>Close the current Customer Details JSP and show a new one.
This will repeat for 10 times and after the last customer details are entered , the Done Button in Customer Details JSP will take the control back to the First Calling Jsp. The First JSP should contain data previously entered.
How can we implement this logic in JSP ??
Thanks & Regards
Saswata Mandal.

by doing your job. You are a programmer right? So design and develop the code to be able to do this. Don't know how? Then you have some reading to do.
Hint: you are doing what seems to be some sort of wizard. Whenever I do a wizard type flow, I use a session bean to store the results of all the steps, to validate and store them all in the final step.

JDeveloper: Viewing a .css on JSP at design-time + run-time

Hi,
As a newbie to JDeveloper, i'm struggling to get a stylesheet reference to work in both the Design view and at run-time. Dragging a stylesheet on to the JSP works fine in the development enviroment, but when the JSP is called from a controlling servlet, the stylesheet doesn't render. From looking on the web it seems i have to use request.getContextPath() to get the path: doing this works at runtime, but in the design view of JDeveloper doesn't show anything (obviously wouldn't because the getContextPath is evaluated at runtime).
Is there a work around so i can see a style sheet rendered in both design & runtime?
Thanks,
Phil

Hi,
Thanks for your reply. When I added my stylesheet (from the component palette) JDev put it in a 'css' folder. When I drag it on to the page it uses ..href = "css/stylesheet.css".. This doesn't work at runtime, neither does href = "/css/stylesheet.css".
To explain the problem better...if I create a new project with 2 jsp files and link them together with Go to page 1 etc this is fine. As soon as I use the mvc method of controlling jsps thorough servlets I can call page 1 fine, but if I linked back to page 2 with the href calling the jsp directly (rather than through a servlet) it won't find the page, because the context root has an extra 'servlet' folder on the path, ie it's looking for page 2 in "Testing-Project-context-root/servlet/page2.jsp", when it's not located in a servlet folder. This is why the css file is not rendering, because it's looking for it in a servlet folder. I can only get round it at the moment by using:
<link type="text/css" rel="stylesheet" href="<%=request.getContextPath()%>/css/stylesheet.css"/>. This of course is no good in the development environment.
Thanks,
Phil

In the install document I see the following:
"Depending on when a failure occurs, the debug logs might not be created in their default locations. In this situation, check the logs for the following directory under the Access Manager web container:
@BASE_DIR@@SERVER_URI@/@DEBUG_SUBDIR@"
I cannot make sense of @BASE_DIR@@SERVER_URI@/@DEBUG_SUBDIR@, can someone shine some light on this for me?

JSP is executed twice

hi,
          I am running weblogic 6.1 with sp4. I have got two JSP which are using a
          datasource to connect to my database (oracle 8).
          When I got a java.sql.connection through the datasource, I am creating a
          statement and executing a query. It is a really simple query (select * from
          mytable) but mostly the JSP will be exceuted twice and I have no idea why.
          So can anyone help me?
          Michael
