Extracting a value from the j_security_check servlet into a JSP page

Hi Folks...
I have a problem as follows:
I log in into the web app, via my login.jsp page. Below is the code for the form that accepts the login information
<form method="POST" action="j_security_check">
<table cellpadding="0" cellspacing="0" border="0">
<tr>
    <td align="right">Username: </td>
    <td><input type="text" name="j_username"></td>
</tr>
<tr>
    <td align="right">Password: </td>
    <td><input type="password" name="j_password"></td>
</tr>
<tr>
    <td></td>
    <td><input type="submit" value="Login"></td>
</tr>
</table>
</form>Login is sucessful and I am brought to the 'studentstub.jsp' page. I would like the user name to appear on the 'studentstub.jsp' page. I used the following code in the 'studentstub.jsp' page :
<td><%= request.getParameter("j_username")%></td> but all I am getting is a null. The 'j_security_check' servlet is not exactly part of my package, but the glassfish app server. Is there anything wrong in the way I am extracting the information from 'j_security_check' ? Hope someone can advise, thanks.

Hi Folks..
I managed to get a reply from another forum and the suggested solution works. I am going to share it with everyone here.
I repalced this line of code:
<td><%= request.getParameter("j_username")%></td>with this:
<td><%= request.getRemoteUser()%></td>The 'getRemoteUser' method from HttpServletRequest returns the name of the authenticated user. I hope this information will be helpful to those caught in a simillar problem. Thanks.

Using WQL "one-liner" to extract a value from the registry

Can I extract a value from the registry using a "one-liner" WQL command? Something like the following:
Under root\default:StdRegProv
SELECT <Data> FROM "HKLM:SOFTWARE\Toto\Version"
Please note that I am aware of how this is done via script. The problem is that I'm using a management system (SCOM), which only allows me to supply a simple WQL query to perform my evaluation.
Thanks,
Larry

How do I Display a string from a servlet into a JSP Page???? NEED HELP!!!!

Hi guys,
How do I Display a string from a servlet into a JSP Page...
Ive tried so many bloody things!.....
Simply.
I get text from JSP. The servlet does what ever it does to the string.
Now. Ive create sessions and bean things,.... how the hell do I display it in a text box... I can display on the screen.. but not in the text box.!!!
please help!!!

hmmm, I dont really like using JSP programming, u should be using JAVA..
the way to do it is:
Call and cast to the bean like this:
<%@ page import="beans.*" %>
<% //cast to bean get request create object
userNameBean u= (userNameBean) request.getSession().getAttribute("userNameBean");
then... all you do is call it like this:
<input type="text" name="firstName" value="<%= u != null? u.getFirstName(): "" %>">
this is the real programmers way,,,

How can I convert (or switch) the RGB percent values from the LR histogram into RGB values which are shown e. g. in PS/CameraRAW?

In LR 5.5 (same in previous versions) the RGB values in the histogram are shown in percent (relativ) values. I prefere to see the absolute values, but I can`t find any way to switch. Maybe this option is intentional disabled, because LR works in 16-Bit mode this would result in values up to 2^16. But as i compared the relativ values from LR with the absolute values from PS i run into a conversion problem. The following example shows the differences:
CameraRAW : RGB, 128,0,0
Lightroom: RGB, 43,8%, 19,0%, 6,2%
CameraRAW: RGB, 0,128,0
Lightroom: RGB, 29,8%, 47,5%, 17,5%
Mainly i have two questions:
1. Is there any possibility to change the percent RGB values in LR to absolut values?
2. How can i convert CameraRAW values to LR values (see above)?

TThe reason that a design decision was made from the beginning of LR to show only the percentage values was that RGB values are dependent on the color space and the LR histogram and numerical readout are derived from the Develop module's display space which is a hybrid color space with ProPhoto RGB primaries and the sRGB TRC. Thus the numerical values in the display would be different from the exported RGB image (in an orthodox space) and it was feared that this would be misleading. When soft proofing was introduced, because it involved converting the display to an orthodox space, it became possible to use the 0-255 scale in that mode.

How to get the value from a database without submitting a jsp page

I have a jsp which has a text box depending on the value entered I want to get the value from a database for other two fields with out submitting jsp page. I am using struts.
Thanks For any assistance provided.

Alright,here is an example for you for the first case.
Present.jsp:
============
<html:html>
<head>
<title><html:message key="page.title"/></title>
</head>
<body>
<html:form action="ChangeEvent.do">
<html:hidden property="method"/>

Emp Id:<html:text property="empId" size="5" onkeyup="if(true){this.form.elements[0].value='populateDetails';this.form.submit();}"/>
Emp Name:<html:text property="empName" size="10" />
Email Address:<html:text property="email" size="10" />
<html:submit>Submit</html:submit>
</html:form>
</body>
</html:html>struts-config.xml:
==================
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">
<struts-config>

<form-beans>
<form-bean name="employeeFormBean" type="org.apache.struts.action.DynaActionForm">
   <form-property name="empId" type="java.lang.String"/>
   <form-property name="empName" type="java.lang.String"/>
   <form-property name="email" type="java.lang.String" />
</form-bean>
</form-bean>
<action-mappings>
<action path="/ChangeEvent" type="Test.GetChangeAction" name="employeeFormBean" scope="request" parameter="method">

<forward name="success" path="/Present.jsp"></forward>
<forward name="failed" path="/error.jsp"></forward>
</action>
</action-mappings>
</struts-config>GetChangeAction.java:
=====================
public class GetChangeAction extends DispatchAction{
public ActionForward populateDetails(ActionMapping mapping,ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception {
        DynaActionForm dForm = (DynaActionForm)form;
        String empId = dForm.get("empId");
        // calling Model / Db and then getting back Employee Details
        EmployeeBean eb = ModelUtils.getDetails(empId);
        // Updating form bean by updating values from the Model
        dForm.set("empName".eb.getEmpName());
        dForm.set("email".eb.getEmail());
        return mapping.findForward("success");
}well to me this should work regardless to any browser but we need to make sure we put in our logic properly.

How include a Servlet into a JSP page?

Hi!!
I need make a combobox with a servlet and place its result into a jsp page.
The servlet is in a package, but when i do: <jsp:include file="sic.view.servlet.ComboServlet" />
tell me that "file attribute isn�t a valid attribute name"
whow can i do to make the combobox whit the servlet and include this into the jsp page??
Thanks!!
PD: Sorry my pour English...

Servlets should be mapped to a URL, then you access the servlet via that URL.
The servlet mapping is done in the web.xml (in WEB-INF/ directory of your web application)
<servlet>
    <servlet-name>
      Combo_S
    </servlet-name>
    <servlet-class>
      sic.view.servlet.ComboServlet
    </servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>
      Combo_S
    </servlet-name>
    <url-pattern>
      /combo
    </url-pattern>
</servlet-mapping>Then you would use:
<jsp:include file="combo" />
to include it.
Make sure the class file gets put in the right package under WEB-INF/classes/

Include a Servlet into a JSP page

Hi guys,
When i try to include a Servlet into my JSP, the execution of the JSP stops...Somebody know why???

Hi guys,
When i try to include a Servlet into my JSP,the
execution of the JSP stops...Somebody knowwhy???
No, and do you know why ? Bcos including a
servlet
in
a jsp doesnt stop the execution of the jsp. Sotell
us that you tried to do, post some relevant
code,
for us to help you.
ram.<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@page buffer="500kb"%>
<html>
<head><title>JSP Page</title></head>
<body>
<jsp:include page="/showCryptValue"
ptValue" flush="true" />
asdfasdfasdfasdfasdf
</body>
</html>
that's the source code....do you have any idea????
Thak's a lottttFrom linxpda:
1) setting the flush="false" parameter for thejsp:include tag?
Here is the problem that I, and perhaps linxpda,
think you have:
You get an exception in the servlet.
You have already written to and flushed the response,
therefore you can not see the exception on your
screen (seeing the exception on screen requires a
send redirect to the error page, which can't happend
when the response is already committed).
The exception that is occuring MAY be alreay written
in your logs, take a look.
To see the problem on screen so as to be able to
identify it, make sure your include tag DOES NOT
flush the buffer. That means change
<jsp:include page="/showCryptValue" flush="true" />
to
<jsp:include page="/showCryptValue" flush="false" />Hi!
No even setting flush false or true it works...If somebody have done this before tell me how have you did....If you can post your code!

To extract null Values from the source in Infopackage selections - Very Urg

Hi All,
I need to pull the data which has null values from source. I tried to write routine by giving l_t_range-low = '' , space. nothing is working.
Please guide me with sample code.
Very Urgent.
Regards
Mano

Hi Mario.
Assuming that you want to avoid uploading of records having
zero for a keyfigure:
Create a startroutine for transfer rules and add this coding:
DELETE DATAPAK WHERE VALUE = '0'.
OR
LOOP AT DATAPAK.
IF DATAPAK-VALUE = 0..
DELETE DATAPAK.
ENDIF.
ENDLOOP.
'VALUE' represents the fieldname in transferstructure
Please let me know if i misundersttod the issue.

I am wanting to exactly match two ID numbers from two differing worksheets within one work book. Once matched I am wanting to retrieve a row value from the second worksheet into the first. Any help much appreciated.

I am wanting to exactly match two ID numbers from two worksheets within the one work book. ID numbers are non linear. Once exactly matched I wish to retrieve a corresponding row value from worksheet two and have it appear in worksheet one against the correct ID number. I have been looking at IF, VLOOKUP, and MATCH functions and suspect that what I want to do requires a combination of two or more. Any help will be greatly appreciated.
regards Vaughanh

Vaughan,
Data A:D is all cells start at column A thru column D.
There is built-in help using the menu item "View > Show Function Browser" in the search field (top right) you can enter vlookup and you will see the detailed description.
From this we see:
VLOOKUP
(search-for, columns-range, return-column, close-match)
search-for: The value to find. search-value can contain any value type.
columns-range: A range of cells. range is a reference to a single range of cells, which may contain values of any type.
return-column: A number that specifies the relative column number of the cell from which to return the value. return-column is a number value. The leftmost column in the range is column 1.
close-match: An optional value that determines whether an exact match is required.
close match (TRUE, 1, or omitted): If there’s no exact match, select the column with the largest top-row value that is less than the search value. Wildcards can’t be used in search-for.
exact match (FALSE or 0): If there’s no exact match, return an error. Wildcards can be used in search-for.
So... the 2,0 means return the value form the same row as the lookup value but from the 2nd column of the range. 3, 0 means from the 3rd column. the ", 0" means exact match

Get value from Table/Recordset Cell into a JSP variable

Can anyone please help with this ?...
I need to get a cell value from a selected row of a table into a variable to pass to a java bean.
1 - The dynamic table is populated by a recordset named "rs" and has a submit button for each row .
2 - The user clicks on the corresponding button to select the row.
3 - The recordset retrieved the ID for that row in the query, but does not display it in the table.
I have tried :
<% String ID = rs.getString("bookid");%>
<% Library.bookConfirm(ID);%>
But this fails saying that it "cannot resolve variable rs..."
Yet the recordset populates correctly and its name is "rs"
Is there another way to do this perhaps ?... ie: put the id in a column of the table and get the cell value ?...
What would be the syntax to get the ID cell value of that selected row on the button click ?...
Your feed back would be greatly appreciated.
Thank you.

Create a new rs
ResultSet rs1 = statement.executeQuery(query);
and use getstring to access the individual cell.

How to Access the Remote Servlet through a JSP Page

Thanks in advance,

Just like any other servlet or form-processing script. What would a mere HTML page know about "systems"? Put the URL into the form destination attribute and be done.

How to get all the values from the dropdown menu

How to get all the values from the dropdown menu
I need to be able to extract all values from the dropdown menu; I know how to get all those values as a string, but I need to be able to access each item; (the value in a dropdown menu will change dynamically)
How do I get number of item is selection dropdown?
How do I extract a ?name? for each value, one by one?
How do I change a selection by referring to particular index of the item in a dropdown menu?
Here is the Path to dropdown menu that I'm trying to access (form contains number of similar dropdowns)
RSWApp.om.GetElementByPath "window(index=0).form(id=""aspnetForm"" | action=""advancedsearch.aspx"" | index=0).formelement[SELECT](name=""ctl00$MainContent$hardwareBrand"" | id=""ctl00_MainContent_hardwareBrand"" | index=16)", element
Message was edited by: testtest

The findElement method allows various attributes to be used to search. Take the following two examples for the element below:
<Select Name=ProdType ID=testProd>
</Select>
I can find the element based on its name or any other attribute, I just need to specify what I am looking for. To find it by name I would do the following:
Set x = RSWApp.om.FindElement("ProdType","SELECT","Name")
If I want to search by id I could do the following:
Set x = RSWApp.om.FindElement("testProd","SELECT","ID")
Usually you will use whatever is available. Since the select element has no name or ID on the Empirix home page, I used the onChange attribute. You can use any attribute as long as you specify which one you are using (last argument in these examples)
You can use the FindElement to grab links, text boxes, etc.
The next example grabs from a link on a page
Home
Set x = RSWApp.om.FindElement("Home","A","innerText")
I hope this helps clear it up.

How can I read an ID-value from the LMS and insert this into an URL?

Hi
Right now I am struggling with a little problem. Hopefully anyone here knows the answer. For the latest course I am building (Captivate 6), it is necessary that at one point the course reads an ID-value from the LMS. After that, this ID should be inserted into an URL.
To be more precisely: the ID must be read (getValue) from cmi.archive_id and inserted into an URL like that: http://.../archive.php?action=pdf&objectID=ARCHIVE_ID.
Unfortunately I am more of a designer und less of a javascript-maestro (well...I am a javascript-noob to be precisely), therefore I am pretty clueless how to do that. I tried a simple executed action (run Javascript: cpEIGetValue('cmi.archive_id'); and after that open URL http://.../archive.php?action=pdf&objectID=ARCHIVE_ID), but...well...that didn't work.
Any ideas?
Thanks a lot in advance

Think you'll find help looking at Jim Leichliter's website:
http://captivatedev.com/
He has great tutorials about JavaScript and also a widget that allows to enter a variable in URL's
