but the part where i'm abit confused, what am i supposed to put in the registration.jsp page?
thanx for the help in advance.

Hi,
In confirm.jsp You can put the error message in a header with response.setAttribute(sMsg, "Please type proper values"); or you can put it in session or cookie.
And get this information in the regestration.jsp and display it.

Problem using jsp:forward in java script

hi,
when I use jsp forward tag inside java script i'm getting a problem that
when the jsp is invoked it is getting forwarded to the page specified in the forward tag, without checking the if conditions. Following code may give you a better idea.
<html>
<script>
function test()
if(document.f.htemp.value=="true")
alert("jus");
else
var s=document.f.htemp.value;
alert(s);
<jsp:forward page="success.jsp" />
</script>
<body>

<input type=text name=htemp value="true">
<input type=button onclick="test()">
</form>
</body>
</html>
please help me,thanks inadvance
regards
chandu

What pgeuens means is that you can't mix javascript and jsp/java code in this way.
ALL of the jsp/java code gets executed at the server end.
This produces an HTML page (with embedded javascript) which gets sent to the client.
The client then runs javascript code in response to events (onLoad, onClick, onChange etc etc)
So in this case, the jsp:forward will always be executed, because as far as the server is concerned, the javascript is just template text.
If you WANT to do a conditional forwarding on the server side you do it in java ie (horribly using scriptlet)
<%
if (testCondition){
%>
<jsp:forward>
%<
%>Or if you want to test what the client has entered client side, all you can do is submit the form, or navigate to a URL
<script>
function test()
if(document.f.htemp.value=="true")
alert("jus");
else
var s=document.f.htemp.value;
alert(s);
document.f1.action="success.jsp";
document.f.submit();
</script>You cannot run JSP code based on your javascript code.
Java. Javascript. Not the same thing.
Hope this helps,

You would need a servlet container to run Servlets and JSPs. And Apache's Tomcat is one such free container available. Download Tomcat from http://jakarta.apache.org and integrate with Apache WS

BeanHome home =

How to use JSP custom tag lib in PAR file?

Hi All,
I am trying to customize mastheaderpar file. For that I have downloaded relevant par file and making the changes accordingly.
As part of the changes I would require to use JSP custom tag library in my par file.
I have the TLD file and relevant classes in the jar file. I would like to know where and what kind of modifications have to be done to use the jsp custom tag library.
I tried modifying some things in portalapp.xml but was not successful.
Please help me on how to proceed with this? It would be great if you can provide the xml entry to use this tag library
Thanks
Santhosh

Hi Johny,
Thanks for the reply. Actually I am able to change colors etc. with out any problem.
My requirement is to use XMLTaglib in mastheader par file. This tag lib is from apache tomcat. I have the relevant TLD and class files. I copied TLD file into taglib dir of portal-inf and class file in src api.
And I have added the following line in portalapp.xml under component-profile section of default
<property name="tlxtag" value="/SERVICE/Newmastheader/taglib/taglibs-xtags.tld">
Is this the right way to use tag lib? Actually before adding this line I used to get the error saying "Error parsing taglib", but now the error does not occur and I am getting new error. This is an exception in one of the taglib classes.
Could any one provide me some inputs on how to check this error?
Thanks
Santhosh

How to use jsp in weblogic 5.1

Hi all,
We have PeopleSoft application running on
Weblogic 5.1 SP12.
How do we use JSP files in this weblogic version ?
We are trying to use a custom jsp file.
Quick help is much appreciated..
Thanks
Maddy

WebLogic 8.1 supports JSP 1.2, which doesn't natively implement the JSTL or the expression language. If you download the Jakarta Taglibs implementation of the JSTL (for JSP 1.2, not JSP 2.0), then you can use the JSTL taglib as a normal taglib. Note that this doesn't give you the ability to use the other JSP 2.0 tag features, like using the expression language in body content.
Make sure that you use the uri value specified in the tld that you're using. I believe the values are different between the JSP 1.2 and JSP 2.0 versions.

How to implement jsp:forward...

I included a <jsp:forward...> directive in my jsp page.
How do I tell that it has only to be executed when
a 'submit' button is pushed ?
Can I add it to the 'action' attribute of a form?

sudhabharathi, yes I tried but remember, I want to create a html-jsp-servlet-jsp environment following the MVC2 rules. Thus jsp with only Beans, servlet which changes the info inside the Bean and forward request to another JSP which display's the info, etc...
When I change the code as :
<FORM action="com.clipper.beans.FQController" method=post target=_parent>
the servlet loads but I cannot get the bean-data into the servlet.
The code in servlet is as follows:
try
     FreightQuotation fq = (FreightQuotation) req.getAttribute("FQ");
     System.out.println("fq object created");
     System.out.println("fq.getGoodsDescription =" + fq.getGoodsDescription());
     FreightQuotationCBean fqc = (FreightQuotationCBean) req.getAttribute("FQC");
     System.out.println("fqc object created");
     System.out.println("fqc.aAS400data.getGoodsDescription() value =" + fqc.aAS400data.getGoodsDescription());
     getServletConfig().getServletContext().
          getRequestDispatcher("../jsp/quotagentdetail.jsp").
          forward(req, res);
catch (Exception e)
     System.out.println("FQController ended abnormally");
     e.printStackTrace();
where executions stops after the message 'fq object created'. The servlets fails at statement:
System.out.println("fq.getGoodsDescription =" + fq.getGoodsDescription());and prints the "FQController ended abnormally" message.
The fq.getGoodsDescription() is a valid getter!
This leads me to the fact that the servlet doesn't receive the bean...

How to use jsp:scriptlet in site template

hi all,
I want to use <jsp:scriptlet> in site template, but jdev showed me an error msg when I put <jsp:scriptlet> in site template:
scriptlet can not work properly with OJSP, I checked the forums, one possible solution is to encapsulate java code in jsp taglib, but I dislike this solution.
Is there a way to disable OJSP? or any solution to use java code in site template?
Best regards

I believe the official word is if you are trying to use java code in a scriptlet in your site template then you are doing something wrong.
The goal is to keep java code separate from the template and pages. Any logic should go to your supporting serviece objects and all of your front-end work should be accomplished using available or custom tags.
Can you describe what you are trying to accomplish with this java code in your template?

How to use RequestDispatcher.forward method in a portlet

I have a servlet (HelloServlet2) that acts as the controller. This is a very simplified example. This servlet calls the dispatcher.foward(req, res) method to foward to a JSP page for displaying. At this point I get a FileNotFoundException. The HelloServlet2 is in the standard location WEB-INF/classes/com/a2i/industrial/servlet/HelloServlet2.java.
How come it's looking in Industrial/servlet/HelloServlet2 instead of Industrial/WEB-INF/classes/..? If I access the servlet by http://host:port/Industrial/HelloServlet2, it works fine. I have another portlet (servlet) that doesn't call the forward method and it works fine too. Thanks for your help.
Here is the web.xml:
<servlet>
<servlet-name>HelloServlet2</servlet-name>
<display-name>HelloServlet2</display-name>
<servlet-class>com.a2i.industrial.servlet.HelloServlet2</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloServlet2</servlet-name>
<url-pattern>/HelloServlet2/*</url-pattern>
</servlet-mapping>
Here is the calling code from HelloServlet2:
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
RequestDispatcher dispatcher= getServletContext().getRequestDispatcher("/hello.jsp");
dispatcher.forward(req, res);
Here is the portlet definition:
<portlet class="oracle.portal.provider.v2.DefaultPortletDefinition">
<id>2</id>
<name>HelloServlet2</name>
<title>Hello Servlet2</title>
<shortTitle>Hello Servlet2</shortTitle>

Thanks for you help David. I changed my code from getServletContext().getRequestDispatcher(jspPage).forward(req, res) to getServletContext().getNamedDispatcher(jspPage).forward(req, res). It worked but I run into the same problem with jsp:include.
I am using the July 2003 of the PDK. I followed the direction for installing version 2 but I did not redeploy with the new jpdk.ear since one was already deployed. After redeploying with the new jpdk.ear, it fixed the jsp:include problem I was having. The problem with using getServletContext().getRequestDispatcher(jspPage).forward(req, res) STILL exist. I am not sure what the deal is.
Oh, I also tried the code below and it doesn't work.
path = req.getContextPath() + jspPage
getServletContext().getRequestDispatcher(path).forward(req, res)
In any case, using getNamedDispatcher() is working fine. I am still curious about getRequestDispatcher() though.

How to use JSP files in virtual directory in WL 5.1

You should be able to just bring the files into DreamWeaver. It should edit the HTML part of the JSP just fine.

How to use jsp:plugin action with type = bean

Hi everybody,
I'm new to JSP so it could be a stupid question but I'm wondering how can I use a jsp:plugin action with a type equal to "bean".
Everyone is talking about type equal to applet so the browser can display this applet but if the type will be a bean so then
does it mean I can send a javaBean class to the client?
If yes, then can the javaBean object be executed on a client machine?
Or maybe I'm wrong. I don't know how it works.
Please give me a resolution.
Thanks,
Rafal.

its not working.. it shows exception class not found exception.
i have placed the jsp and applet class in the same folder. but its not working.
jsp file path : OracleSpatial\mypackage\webmap.jsp
applet class : OracleSpatial\mypackage\demoApplet.class
demoApplet class inside package "mypackage".
code inside JSP is :
<jsp:plugin type="applet"
code="mypackage.demoApplet.class" width = "100%" height = "100%" >
</jsp:plugin>

Hi Sam,
To Use properties file you need to keep the properties file in a location and in the code you need to mention the path from where it should read in the runtime.
Fuego.Io.PropertiesFile propfile;
propfile.load(fileName : "<Path: C:/sample.properties>"); //Path: Place the properties file in the respective directory/drive and mention the path
String val = propfile.get(key : "One"); //One - is the key against which the value should be mentioned in the properties file like <One = 1>. It should return 1
logMessage("Value: " + val);
To use the Enum in your project first create a Module in your catalogue component and then right click on module create New Enumeration say ProcessStatus
Uncheck the Is Sequential if you want to keep key/value as pair. Click on add +* and mention the Name and Value say ABORTED as Name and Value as Aborted. To use it in your project conditional path write the condion as somevariable == String(ProcessStatus.ABORTED)
Hope this will help you.
