JSP, javascript and maps

Hi,
using HTML/JS form, the user chooses an empty map(say usamap.jpg). he also chooses a text file that contains data about the map. the user is also allowed to choose a color that denotes a particular range ie all regions in the range 1000 to 2000 to be represented by pink color.is it possible to use JSP such that the color chosen by the user(ie pink) is applied to specific regions on the map?
some examples with code will be helpful. thanks in advance and waiting to hear from u.

Hi bsampieri,
i am giving a detailed problem of mine below:
i have an blank outline map of Europe (ie it contains only the boundaries of each and every country) . This map is in SVG format.
also i have a text file that contains the name of each country with their respective population values.
now i need to use servlet or JSP to acheive the following functionality:
all countries in one particular range are to be given a color, countries in another range are to be given another color etc. for example say Spain, France and Denmark all lie in the same range say(10000 to 30000). england, italy and sweden lie in the same range say (40000 to 60000).
now i want to use servlets/JSP such that spain, france and denmark are represented in pink color while england,italy and sweden are to be represented in blue color etc
how can this be done?
hope i made things clear.
thanks in advance

Evaluation of excel formula to jsp/javascript

hi,
i am having one typical problem (this is returns on investment(ROI)based)i am having a formula in excel sheet that has to be implimented in jsp or java script. the inbuilt function in excel is NPV
NPV($F$11,H19:Q19)+G19(it is like this in my formula bar)
Syntax
NPV(rate,value1,value2, ...) even some formula is given in the help
can anybody help me how to calculate this using jsp/javascript and can give me the src code for this calculation.
thanks in advance
regards,
srikanth

Calculating the IRR is an iteration.
You try different interest rates until the NPV is as close
to 0 as you can get.
To calculate the IRR you will need the following:
(1) A starting point for the rate (the 'guess' argument in Excel)
(2) Your cash flows array (the 'values' argument in Excel)
You will also have to decide:
(3) How many attempts to make before giving up.
(4) How close to NPV = 0 is acceptable
(5) How to increment the interest rate
Now you make a loop.
Calculate the NPV.
If the NPV is > 0 try a higher rate.
If the NPV is < 0 try a lower rate.
If you are 'close enough' then return the rate.
If you have exceeded your maximum attempts then return
some value like 'not-a-number'

How does *.jsf extension map to *.jsp extension and where it is mapped

Hi ,
How does *.jsf extension map to *.jsp extension and where it is mapped ?
Thanks

How does *.jsf extension map to *.jsp extension and where it is mapped ?It is mapped in the web.xml.
If you add the following in your web.xml:
<context-param>
<param-name>javax.faces.DEFAULT_SUFFIX</param-name>
<param-value>.xhtml</param-value>
</context-param>
The *.jsf will be mapped to the file with the same name, but xhtml as extention.
if you the javax.faces.DEFAULT_SUFFIX is not defined in the web.xml, the default suffix comes from the one of the constant of javax.faces.application.ViewHandler . This constant names DEFAULT_SUFFIX and equals to ".jsp"
Look at:

Parameters b/w javascript and JSp

how i can pass values between javascript and jsp .
( java script varaible in the JSP part & jsp object in the javascript code )

Since Java script is on the client side , to get the value of a java script variable into jsp, u have to set some form field variable and submit it to the server again. So, it can be something like:
<script>
function submit()
     var scriptVar = 12;
     document.form1.formVariable.value=scriptVar;
     document.form1.submit();
</script>
<%
System.out.println("Script variable value = " +request.getParameter("formVariable"));
%>
<form name="form1" method="post">
<input type="hidden" name="formVariable" value=""/>
<input type="button" name="bSubmit" value="Submit" onclick="javascript:submit()" />
</form>
The first time this jsp is called, the value of formVariable will be null.
The next time, when u click on submit button, the value will be 12.
I have not tested this. There might be some syntax errors. Just try it out. Also, make sure that u don't end up submitting the form in an infinite loop by using the submit() generally in the script. Hope this helps.

Mix JavaScript and JSP

Hi.
I have jsp and javascript mixed when I click a check call a function javascript for example:
//JavaScript
function Hola(numerop) {
idRol = Number(numerop)
<%nombreRol = roles.get(numerop)%> }
//Form
<input type="checkbox" name="<%=roles.get(sum)%>" value="<%=roles.get(sum)%>" onClick="Hola('<%=roles.get(sum)%>')">
In the function numerop is a number but in the jsp code numerop is undefined.
How I can mixed javaScript and jsp??
Please I need help you.

Remember that the JSP runs on the server and generates the HTML, including Javascript. The Javascript runs on the browser after the JSP is finished. So you cannot do whatever it is you expected that to do.

How can I stop the execution on a JSP page and start it again

Hi
I am making a program that simulates how to manage transactions when accessing a database by using locks. I have run into a problem and I hope someone has the time to help me.
When a user does an update the transaction commits and releases its locks when the program executes
<%stmt.executeUpdate("commit!"); %>
I need to put a break in to stop the program executing this statement, to illustrate the lock is set correctly.
I have tried to put in an alert box but this does not prevent the rest of the java code being executed.
I have tried to use prompt boxes, JavaScript functions, but these functions cannot have any java code in them.
I have tried using the java.swing JOptionPane boxes but this didn?t work either
I have tried to get input from the user but I don?t know how to retrieve this data on the same page. (As far as I know you have to use submit and even refresh the page or retrieve it on the next page).
Does anyone know how I can stop the execution on a JSP page and start it again (on same page)
Mette

I already have another client (Tomcat jsp application) running and it throws a SQLException correctly when I don�t put in a commit=true statement and don't close the database connection.
But the problem is how to get the code above to stop to illustrate I have set this lock.
I have tried to use the JOptionPane but because my program is running in a web browser I cannot use the JOptionPane dialog box.
I have tired using an alert box but it executes the commit statement before the alert box is dispayed. So this does not work
While (i < 2)
if( i==1)
%>alert(�The transactions commits when you press Ok�); <% //what it to stop execution here
else
stmt.executeUpdate(�commit�);
I am not using threads so I cannot use the sleep function.
I am using mysql and have already configured it to detect deadlocks and how long to wait for locks.
Thanks for your help
Mette

Javascript and Struts HTML problem

Hi all,
I write the following script in my jsp page, but this one does not produce the output at all :
<script type="text/javascript">
document.write("<input type="button" value='<bean:message key="btn.show"/>' onclick='onShowClick(this.form,"<bean:write name="vo" property="id"/>",true)'/>")
</script>While the following script without Javascript works as expected :
<input type="button" value='<bean:message key="btn.show"/>' onclick='onShowClick(this.form,"<bean:write name="vo" property="id"/>",true)'/>What is wrong ?
Thanks in advance,
Setya

Sure theres an easier way - don't use javascript?
Why do you want to do this javascript and document.write?
Can't you do it using JSP?
About the quotes:
The same quote that starts a string, ends it.
You are writing a javascript string, so the first unescaped single quote it comes across will end it.
Unfortunately in the middle of this string, you are writing HTML onclick event, with some javascript which ALSO needs quotes escaped(sigh)
So you have a javascript string producing some HTML, which also embeds a javascript string (now thats complicated quoting). Mixing the quotes with the struts tags just makes this a nightmare.
If you want to use quotes in the middle of a string you have to escape them.
Simple examples:
document.write("hello world"); // no quotes
document.write("hello \"Java\" "); // escaping the quotes
document.write('hello "Java" ') // because we used a different quote, we don't have to escape it
And mixing the two:
document.write(' hello "Java\'s buddy" '); // double quotes don't need to be escaped but the single quote does.Your line of code should be
document.write('<input type="button" value="<bean:message key="btn.show"/>" onclick="onShowClick(this.form,\'<bean.write name="vo" property="id"/>\',true)"')Note that I escaped the single quotes around the string attribute to the javascript method. Needed to do this, so as not to disturb the double quotes encapsulating the onclick="..." method.
Good luck,

How to use javascript and scriptlet simultaneously

Hi all!!
I have a jsp page on which there are two selection lists. One is for publisher names list and second is for journal names list corresponding to publisher selected in first selection list.
When publisher name is selected in first selection list then all journal names should be listed in second selection list. it requires fetching rows in database.
ie; action is onChange of first selection list ie; javascript and database is of scriptlet part.
how to do that??
I know that scriptlet can't be used in javascript. and it is possible by submitting this form. but i don't want to submit this form.
Please help me out.
Thanks

Hi _abhi,
Use the onchage action in the drop down tag which will redirect using URL encode to the same page and get the parameter data and pass the value to the second Drop down
Cheers

Access Custom Attributes in JavaScript and in Transactions

Hello,
I try to work with custom attributes. I've problems accessing the values in JavaScript and in transactions, but it works fine within .irpt pages.
What's the trick?
For a custom attribute called PLANT, can I write something like this in JavaScript?
var p = ;
Is there a way to access custom attributes in the Link Editor of an Action Block?
Kind Regards,
Matthias

Hi Matthias,
it is not possible to integrate that kind of MII variables in JavaScript like you discribed before.
You are right that this kind of expression is possible in the .irpt file. The reason why it is working in the .irpt
but not in the .js is, that the MII script parser is only replacing in HTML content. Everywhere you have
scripting the parser will not replace the {...} markings (since the curly brackets also show start/end of functions aso.).
Variables to JavaScript
The easiest Way to get those variables is to create hidden fields in the .irpt file that you can access via JavaScript.
For example:
<input type="hidden" id="hidden_plant" value="{PLANT}" />
This will be parsed to (e.g.)
<input type="hidden" id="hidden_plant" value="Karlsruhe/DE" />
Now you can access this value in JavaScript via:
document.getElementById( "hidden_plant" ).value;
Variables to Transactions
To parse custom variables to a transaction you first have to specify corresponding transaction variables in the
transaction itself. After saving the transaction you can map those variables to Parameters in the Xacute-Query-Editor.
Including this transaction to your webpage you can simply assign the required value to the corresponding parameter.
For example if you mapped the Plant variable of the transaction to Param.1 you can specify the information in the .irpt
like:
<applet id="trx_test" ....>
<... />
<param name="Param.1" value="{PLANT}" />
</applet>
Another possibility is to set the value dynamically via JavaScript if you use:
document.getElementById( "trx_test" ).getQueryObject().setParam( 1, "Karlsruhe/DE" );
Native access to user variables via the BLE is not possible (as far as I know).
I hope this is what you wanted to hear?
Best Regards
Sebastian

The content type for office excel 2007 in jsp page and the mime-type in we

Hi,
In my system MS Office 2007 is installed. I am trying to generating excel sheets from JSP page by setting the content type "application/vnd.ms-excel" in jsp page and as well as in web.xml file. I am getting the below message
The file you are trying to open, 'xxxxxxxx.xls', is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?
Then finally the excel file is opening and displaying properly. If in my system MS Office 2003 is installed , then the above message is not coming.
I have changed the content type according to Excel 2007 <%@ page contentType= "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" %> and in web.xml file the mime type to
<mime-mapping>
<extension>xlsx</extension>
<mime-type>application/vnd.openxmlformats-officedocument.spreadsheetml.sheet</mime-type>
</mime-mapping>
even the content type is changed according to office excel 2007 , i am getting the same above message.
My client is asking not to display the above message. So how to prevent that message ?
It's very great if any body reply me as soon as possible.

Are there known issues concerning double clicking in FF? We found bug 542068. Most of the issue we found have to do with Flash. Does it affect other applications (JSP/Javascript) too?

Are there known issues concerning double clicking in FF? We found bug 542068. Most of the issue we found have to do with Flash. Does it affect other applications (JSP/Javascript) too?

If there is a pattern of the application working up to Firefox 3.6.3 and not working starting with Firefox 3.6.4, there could be a problem with trying to communicate events between firefox.exe (which hosts pages) and plugin-container.exe (which hosts some plugins). You can tweak your settings to force plugins to run in firefox.exe to see whether this is the problem. This article has some background information on that:

''Do you know if there are problems with Firefox 3.6 when you double click in a JSP/JAVA/Javascript application?''
No, I don't know. Obviously I can't read every post here, but I haven't read about it before.
Is it a stupid question to ask: why does that matter?? To fix the application to work in Firefox 3.6 and above, we need to see a page that works on other browsers and fails in Firefox. It doesn't need to be the whole application, just enough to demonstrate the problem so that if we solve it, then you can apply that learning back to your application.

Ovi Suite and Map Server connection error when beh...

Hi All,
from many recent versions up to the latest 3.1.1.80 I have problems to connect to the map server when behind a proxy. Ovi Suite correctly access to internet and log on (I've set-up proxy access data in the options menu) but when I access to the Maps tab I receive the massage "MAp Server not available".
Now I've understood the reason and for nokia guys it should be very easy to fix the problem:
if my proxy username is in the format "name surname" Ovi Suite access to internet but Maps DOES NOT.
if my proxy username is in the format "username" (without spaces) BOTH ovi suite and Maps WORKS correctly.
Please FIX it, it should be very easy.
Thanks,
AleC

Hello, 1. Were you able to use the usb connection if present? And also, make sure you have the correct drivers, if present, installed (use a device manager to check). 2. Most probably, your printer was not properly connected to the network. You need to check IP configuration. If a wireless router is used, make sure there is no MAC filtering enabled. If enabled, you need to reconfigure. 3. DHCP Service. 4. Check the network test page and make sure ssid is correctly identified. And the rest of the wireless parameters. 5. Make sure your firewall does not blobk printer connections. Make sure file and print sharing has been turned on for the appropriate network with network discovery turned on(Network and Sharing Center if Windows). Network connection should be work not public (Windows only). More assistance: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&taskId=110&prodSeriesId=... Thank you!
