Java Script and JSF question

Hello,
I have a JSF component like this that has a pageSize attribute. It shows a grid with 5 elements.
<x:gridView id="#{tab}GridView" pageSize="5">
</f:gridView>Then I have a drop down with 5 menu items where the user can select how many elements they want to see visible on the grid. My question is, how do i use Java Script to to change the pageSize attribute above with what the user selected in the menu below? I have been looking at java script code and online docs for an hour and cant come up with anything that seems to work. Any help will be appriciated. Thank you!!!
<x:selectOneMenu id="myMenu" onclick="">
<f:selectItem id="perPage1" itemValue="1" itemLabel="1" />
<f:selectItem id="perPage2" itemValue="2" itemLabel="2" />
<f:selectItem id="perPage3" itemValue="3" itemLabel="3" />
<f:selectItem id="perPage4" itemValue="4" itemLabel="4" />
<f:selectItem id="perPage5" itemValue="5" itemLabel="5" />
</x:selectOneMenu>

[...]how it was never designed to be used for
such large applications[...]All I can say is that if this is true, then it doesn't show. Yes, I know it (oak) was originally designed for embedded systems, but Java and Oak aren't identical.
My assembly teacher
always makes fun of Java, saying java gives you far
less control, it prevents you from making mistakes.
No control over unsigned/ signed values, pointers
etc. Yes. But broadly speaking that's the point. Java sacrifices control over such things. The return, however, is that programmers are able to be more productive because of the great swathes of problems that can no longer arise.
The mistake is in assuming that Java is the best tool for everything. It isn't, and in fact no language us. As it turns out, Java is just great for building enterprise systems. It has a few other strengths, some of which (applets for example) have been more important in its original uptake but are now relatively minor features.
You don't write an enterprise website in Intel assembly, and you don't write device drivers in Java.
Not saying its not good but its good for
smaller applications like cell phones and
mini-computers.I think you mean something different by mini-computers to what I mean...
Its portability is actually the main point in its favour for use in cell phones. If it weren't for that, I think C or C++ would probably have sole ownership of that space.
Now i'm not saying any thing against it just
confused on why a class like data-structures at my
University [...] would be taught using java when C would
probably be a lot better for Very Large ADTS.You and Joel Spolsky:
http://www.joelonsoftware.com/articles/ThePerilsofJavaSchools.html
I disagree, because I don't think it much matters what language you learn - experience trumps any particular initial language choice. If you're still using Java in 15 years I'll be fairly surprised.

Java Script and JSF

Hi All,
I have a problem with JSF and javascript in dataTable.
I would like to have an image that has mouse over and mouse out event that also get a parameter from the table. the html code is like this:
<img src='../images/blt_cl_help.gif' border="0">
My problem is that I can not use <f:verbatim/>, since the John parameter on onMouseOver="return drc('John,'Job Description:'); is coming from my bean. How can I solve this problem?
Thanks

What're the differences between JSP, Java Script, and Java Applet?

I am confused by the concepts: JSP (Java Server Page), Java Script, and Java Applet? What are their main differences?

I don't know about differences, but one of their main similarities is that each of them has a page in Wikipedia.
JSP
JavaScript

Problem in merging java script and java code

hi,
i want to merge java and javascript code but it is giving some surprising results.
this is my code:
<script language = "javascript">
<%
String query_result= "1";
String buttontype="";
buttontype=(String)session.getAttribute("buttontype");
query_result = (String) session.getAttribute("query_result");
out.println(query_result);
if(buttontype!=null&&(buttontype.equals("submit")))
out.println(buttontype);
%>
alert(<%=ka%>)
</script>
<%
%>
now if i'll move "<script language = "javascript">" to:
<%
String query_result= "1";
String buttontype="";
buttontype=(String)session.getAttribute("buttontype");
query_result = (String) session.getAttribute("query_result");
out.println(query_result);*/
if(buttontype!=null&&(buttontype.equals("submit")))
out.println(buttontype);
%>
<script language = "javascript">
alert(<%=query_result%>)
</script>
<%
%>
then it prints correctly and gives alert "1" but if i'll change query_result="manish" then it is not giving alert also
i don't know wht is happening
plz help me out
manish

hi pgeuen,
Thanx for ur reply
now its working i have changed my jsp exp. tag to
alert("\"<%=ka%>\"")
and it is displaying correctly.
and if i'll give the scripting tags in "if block"then it will work but till now i didn't get why i was not getting any output when the scripting tags covers the whole jsp code. i think we can mix java script and jsp in any way.
well thanx a lot.

What is java script and how do I enable it?

What is java script and how do I enable it

JavaScript is enabled by default for Adobe Reader for iOS, and I don't see that there's a way to disable it. It is currently used within a document to control the behavior of form fields, such as automatic formatting and calculations. Only a small subset of what's available in the desktop version is available in the mobile versions.

Can a Button call a java script and then proceed with the creation

Hi all,
I have a simple APEX form on a table,
with simple function as create and apply changes,
some items of the form are computed by a "Computation"
I need the create button to show the computed values, before move to the next page, then proceed with the creation ( submission)
I have tried to show the values by a java script, but after clicking the button OK of the javascript msg, no submission performed ,
details:
the java script is called in the URL of the Button,
it only contains a alert statement
is there a way to let the button do that
or may be the case could be solved by another idea!!!
rgrds,

Hi Varad,
It is Before header of course. I forgot to mention this.
Yes, you are right Varad, I have read again the question and seems original request was to show Computation that is done in After Submit, more javascript is required of course.
One possibility is to create On Demand process called COMPUTEITEM where you compute your item, and in the end of on demand process it prints it
htp.p(:P1_X)
Then put in HTML header of your page
<script language="JavaScript" type="text/javascript">
function setShowItemSub(pThis){
   var l_This   = $x(pThis);
   var ajaxRequest = new htmldb_Get(null, $v('pFlowId'), 'APPLICATION_PROCESS=COMPUTEITEM', $v('pFlowStepId'));
   ajaxRequest.add($x(l_This).id, $v(l_This));
   var gReturn = ajaxRequest.get();
   alert(gReturn);
   ajaxRequest = null;
doSubmit('aa');
</script>And in Button URL textarea put:
javascript:setShowItemSub('P1_X');
Then no need in After Submit process anymore
I have put this now in http://apex6.revion.com/pls/apex/f?p=225:1
COMPUTEITEM On demand process is :
:P1_X := :P1_X || ' Added this trail';
htp.p(:P1_X);Of course, all this should be modified accordingly

Oleg

Doubleclick, banners, java script and K size

I've been making flash banners for 10 years and now am trying (unsuccessfully) make banners with adobe edge. The reason I say unsuccessfully is because of the 100k javascript files that are associated with the project. Anyone who makes banners 300x250, 728x90, 300x600, etc.... knows that the typical k size is 30-50 kilobytes. this isn't possible with the k size the java script ads to the project.
Doubleclick studio wont let the dns files be hosted.
Now I'm wondering if this is an antiquated method of gauging the effect a banner has on a website. My question is, should java script count towards the final K size of a banner? isnt it typically loading images that the publishers are concerned with?
Does a 100k java script file take up the same bandwidth of loading an image onto the site? I'm not sure how I could convince such large entities to change how they view the spec sheet but if as i suspect java script shouldn't be lumped into the same category as images then maybe I can convince someone to change the required specs and split it into "images" and "java script" kilobyte sizes.

I kind of doubt that it is in JRE issue, since Java and Javascript have not much to do with each other.

J2EE, JSTL and JSF questions

I am trying to learn J2EE/JSTL/JSF and have quite a few general questions. Any help on any of these is appreciated.
1) Is there a way, just by using J2EE/Java to "manipulate" an XML file. Not just parse and read it's data but actually add nodes to the file?
2) I've been reading quite a bit on JSTL and JSF recently. Is JSF supposed to be an alternative to Struts and JSTL an alternative to scriptlet coding?
3) I am also working on creating a message board but throwing around a couple of ways to implement it. Either (a) using a database to store posts and a JSP interface or (b) using an XML document to store postings. Which of these two seem best or is there a better option?
4) Is there an easy way to call Php from a Java program? I need to invoke a php program when a user clicks on a link on a JSP page I have.

1) The SDK provides JAXP (Java API for XML Processing) in javax.xml package.
2) I wouldn't call it 'alternative'.
3) Your choice. I'd to use a RDBMS. Less overhead, better suited, (much) more functions and better performance.
4) If that program is available on the web, then just invoke a HTTP request. If not, I'd rather to rewrite it to Java.

Share variable value between java script and jsp

Hi, Firends:
In my old web page I used a static array to hold a set of values, and now I want to use dynamic value from datbase.
I created a bean to process database data and return resultset value to an array string.
I convert my html page into jsp page, use "usebean" tag to call specific method, after done, how can I set the
resultvaule to my script variable?
It's urgent!! great thanks!

Hello,
Finally, the codes work! thanks for all the suggestion!
The most important is "J" need <%= tag too. and do not forget the double quotation mark ("") while assigning the value.
the code like following:
<jsp:useBean id="ArrayBean" class="myProj.BeanServices"
scope="page" >
</jsp:useBean>
<%! public String[] dataArray; %>
<%
dataArray = ArrayBean.getRecordsetReturn();
%>
<script language="JavaScript1.2">
var MCC = new Array(<%=dataArray.length%>);
<%for(int j =0; j < dataArray.length; j++){ %>;
MCC[<%=j%>]="<%=dataArray[j]%>";
<%}%>;
</script>
One more question:
I found on the web server, if I used the same file name (asp file and js file, html file is ok.), seems the server always used the old compiled codes ignoring the code already changed, even after re-complile. I have to change the file name again and again.
I worked on JDeveloper environment, it has a testing web server environment on my local, I am not sure if this situation will happen in the real server environment.
How can I make any new updates go into effect immidiately! Do you know web server has some configuration to handle this?
Thanks a gain!

Java script and scriplets

Hi,
I have got a .jsp page wherein there is a 2 dimentional string array defined within a scriplet.
I have defined an other function in java script within the same page.
Now I need to access the string array within the java script. Can someone please hep me how to achive this...
I tried something like this, but its not working:
function displayNameIndex()
var source = <%= imgArrayName %>[0][0];
where imgArrayName is the name of the String array in the scriplet code.
Many thanks

JSP is executed at the serverside and generates a long HTML string. Javascript is part of this HTML string. Once this string is arrived at the client, the JS will/can be executed.
What you're expecting here is that the Javascript is able to access the Java Object which is converted into a simple plain vanilla string. That is not true. Better is to put all of this logic in the server side or in the client side. You may need to iterate through the Java String[][] object and print all values into the response, so that JS can access them.

Java script and Servlets

Any body can give a sample program how can i included a java script in a servlet program
Regards
Marimuthu

What exactly are you trying to achieve?
This is a typical servlet with raw html. You can also put javascript there the same way html is there.
public class FirstServlet extends HttpServlet {
public void doGet(HttpServletRequest request,
    HttpServletResponse response) throws ServletException,
      java.io.IOException {
    //set the MIME type of the response, "text/html"
    response.setContentType("text/html");
    //use a PrintWriter to send text data to the client who has requested the
    //servlet
    java.io.PrintWriter out = response.getWriter( );
    //Begin assembling the HTML content
    out.println("<html><head>");
    out.println("<script language='javascript'>alert('Hello Muthu');</script");
    out.println("<title>Help Page</title></head><body>");
    out.println("<h2>Please submit your information</h2>");
   //make sure method="post" so that the servlet service method
   //calls doPost in the response to this form submit
    out.println(
        "<form method=\"post\" action =\"" + request.getContextPath( ) +
            "/firstservlet\" >");
    out.println("<table border=\"0\"><tr><td valign=\"top\">");
    out.println("Your first name: </td> <td valign=\"top\">");
    out.println("<input type=\"text\" name=\"firstname\" size=\"20\">");
    out.println("</td></tr><tr><td valign=\"top\">");
    out.println("Your last name: </td> <td valign=\"top\">");
    out.println("<input type=\"text\" name=\"lastname\" size=\"20\">");
    out.println("</td></tr><tr><td valign=\"top\">");
    out.println("Your email: </td> <td valign=\"top\">");
    out.println("<input type=\"text\" name=\"email\" size=\"20\">");
    out.println("</td></tr><tr><td valign=\"top\">");
    out.println("<input type=\"submit\" value=\"Submit Info\"></td></tr>");
    out.println("</table></form>");
    out.println("</body></html>");
    }//doGet
public void doPost(HttpServletRequest request,
    HttpServletResponse response) throws ServletException,
    java.io.IOException {
    //display the parameter names and values
    Enumeration paramNames = request.getParameterNames( );
    String parName;//this will hold the name of the parameter
    boolean emptyEnum = false;
    if (! paramNames.hasMoreElements( ))
        emptyEnum = true;
    //set the MIME type of the response, "text/html"
    response.setContentType("text/html");
    //use a PrintWriter to send text data to the client
    java.io.PrintWriter out = response.getWriter( );
    //Begin assembling the HTML content
    out.println("<html><head>");
    out.println("<title>Submitted Parameters</title></head><body>");
    if (emptyEnum){
        out.println(
           "<h2>Sorry, the request does not contain any parameters</h2>");
    } else {
    out.println(
        "<h2>Here are the submitted parameter values</h2>");
    while(paramNames.hasMoreElements( )){
        parName = (String) paramNames.nextElement( );
        out.println(
            "<strong>" + parName + "</strong> : " +
                request.getParameter(parName));
        out.println("<br />");
    }//while
    out.println("</body></html>");
}// doPost

Java(script) and WD4A

Hi all,
I know you can't use any javascript in WD yourself, but after creating a WD component / application, the code that is generated, does it contain, beside HTML code any java(script) or some other kind of scripting?
If so, what kind of scripting should I think of and what does it do?
Kind regards,
Micky.

> Thanks for the quick reply (even on a sunday). Just for my understanding: The fact that you cannot enter your own javascript like in BSP, lies in the fact that SAP wants to make WD platform independent, correct me if I'm wrong? So how does SAP ensure this by using javascripting when generating the WD webpages? Doesn't this make it platform dependant?
We aren't just shooting for independence between browsers (IE vs. Firefox) but entire clients. In Web Dynpro you will soon be able to run the same application in a Browser or the Flex Client or the NetWeaver Business Client without changing anything in your application - the later two don't even use JavaScript or HTML.
Now how do we ensure cross-browser support in JavaScript - well nothing really special there. Sometimes it takes separate JavaScript libraries and sometimes it just takes branching logic within a JavaScript function. Most of the differences between the browsers are pretty well documented and although a pain to deal with not really that much of an unknown. Still better to let one small group of UI foundation developers have to deal with than all the thousands of application developers.

Java script and password request

Hi, this is my husband's play book and he is having a couple of problelms with it at the moment..
1.First:
When he tries to load a paticular app, he gets a java script error "null" message..I loaded the same app on my phone (Galaxy S III) and it worked fine but it doesn't on my DH's or my DIL's BB Playbook..
2. Password Request:
While reading his ebooks,BB playbook keeps asking for him to supply his password again..he "save"s it each tie and then it asks him again a few minutes later..same happens if he selects "cancel"

which means??
so who's problem is it that it doesn't work?? Blackberry or The Citizen Developer?? this only started all of a sudden..up till just recently, there was no problem with this app..and deleting it and reinstalling it doesn't help..

Java script and the new and not improved firefox don't work. Please let me be able to run Java again.

I use SAP Infoview for work. To modify reports it requires a Java script to run. I had it set up in the previous version of ff to always allow from this specific site and it worked wonderfully. Now, in the new version, despite following all of the instructions from others, I cannot do my work because I cannot run Java script. I can still run it in Safari, but Safari is a last resort for me to use. I prefer Firefox and have all of my links stored there.

Some sites are not fully compatible with Firefox 4's new HTML5 rendering engine. Can you turn that off and test without it? Here are the steps:
(1) Open a new tab, then type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste '''html5''' and pause while the list is filtered
(3) Double-click '''html5.parser.enable''' to toggle it to false (it should turn bold).
Then change back to the SAP tab and reload the page.
Does that make any difference?

How to create two level dynamic list using JSP , Java Script and Oracle

I am new in JSP. And i am facing problem in creating two level dynamic list using JSP ,Java Script where the listdata will come from Oracle 10g express edition database. Is there any easy way in JSP that is available on in ASP.NET.
Plz response with details.

1) Learn JDBC API [http://java.sun.com/docs/books/tutorial/jdbc/index.html].
2) Create DAO class which contains JDBC code and do all SQL queries and returns or takes ID's or DTO objects.
3) Learn Servlet API [http://java.sun.com/javaee/5/docs/tutorial/doc/].
4) Create Servlet class which calls the DAO class, gets the list of DTO's as result, puts it as a request attribute and forwards the request to a JSP page.
5) Learn JSP and JSTL [http://java.sun.com/javaee/5/docs/tutorial/doc/]. Also learn HTML if you even don't know it.
6) Create JSP page which uses the JSTL c:forEach tag to access the list of DTO's and iterate over it and prints a HTML list out.
You don't need Javascript for this.
