NetBeans and JSP pages
I'm using the netBeans IDE to develope my project and the project is web application. But I've a problems with this IDE.
Q1. The default page is index.html and the default home for the project is say $HOME, when I write http://localhost:8084/$HOME/index.html the browser displace error message. I've to run this file from the netBeans. Do I need to run netBeans and run the file from the IDE to access the index.html file?
Q2. The second problem is; once I run the index file from the netBeans and then use this address http://localhost:8084/$HOME i.e if I remove the index.html file form the URL the Browser displays all the files that I've in my project but I don't won't this to happend. Is there any means to avoid this problem?
Thank you indavance.
I'm using the netBeans IDE to develope my project and
the project is web application. But I've a problems
with this IDE.If you are new to application development, then I recommend not using any IDE - it is better to configure everything manually http://tomcat.apache.org/tomcat-6.0-doc/appdev/index.html to understand what's going on under the hood.
Once you understand what's going on, then it will be much easier to configure your IDE.

Hi.
I have a class called clsDbGrid under the ./classes/pkgDB and a JSP page under de ./web directory. I need to call the class from my JSP. I wrote the follow code:
<applet class="clsDbGrid.class" width="640" height="480">
The browse doesn't support JAVA
</applet>But this code doesn't work. What's wrong? I put the entire path for package and doesn't work again.
Please, I'm beginner in Java and need a help.
Thanks.

PAR files and jsp pages into NWDS
Hi,
I need to modify transactions from the MSS 50.x package, i.e. HR transactions. I need to delete some fields on the screens.
The sysadmin was giving me a par file
com.sap.pct.hcm.attendanceoverviewperiod.par.bak
But when I import the par file into NWDS, the only thing I see is the portalapp.xml and a bunch of attribute files.
No jsp page, no class files..
When I browse into the directoria via sysadmin/support/portal runtime via WEB-INF, I do see all the necessary files. But how do I get the whole bunch of classes, jsp etc into NWDS? Download all single elements and put them manually into a NWDS project? There must be a better way
Any help will be gracefully awardedI tried it, but when I follow your instruction, NWDS gives me an error in the import wizard "<dir> does not have a .project file".
If I look in the .par file, there is no .project file at all.
I looked in the download of the PCD, there is no .project file either, but at least the java classes and the jsp.
Is it removed intentionally? Probably because it is an SAP business package? -

Pass Object Between Applet and JSP Page
Hi all,
How can I pass an Object(such as Vector, File), rather than just string to the Applet from a JSP page?
Thank you.I used Base64Encoder and Base64Decoder from servlets.com utilities.
* convert any serializable object to a String
public synchronized static String objectToString(Serializable obj) throws Exception {
ByteArrayOutputStream bos = new ByteArrayOutputStream(100);
ObjectOutputStream oos = new ObjectOutputStream(bos);
oos.writeObject(obj);
byte[]bytes = bos.toByteArray();
bos = new ByteArrayOutputStream(); //to save the encoded String
Base64Encoder enc = new Base64Encoder(bos);
enc.write(bytes);
String encodedString = bos.toString();
//close all
enc.close();
oos.close();
bos.close();
return encodedString;
* Recreates the object from the encoded String
public synchronized static Object stringToObject(String str) throws Exception {
ByteArrayInputStream bis = new ByteArrayInputStream(str.getBytes());
Base64Decoder dec = new Base64Decoder(bis);
ObjectInputStream ois = new ObjectInputStream(dec);
Object obj = (Object)ois.readObject();
ois.close();
dec.close();
bis.close();
return obj;

Applet to Applet communication between two seperate threads and jsp pages
Hi,
have two java applets running on two separate jsp pages. I am trying to have one applet talk to the other applet. I have tried putting the applets in a static hashtable, but I found out (through trial and error) that the memory is not shared between the applets. Needless to say the appletcontext object will not work as well. I have also tried to put the applet threads into a thread group, but it seems that the second applet can't find the first applet's threads. Is there a funky way that I need to create the threads for the threadgroup? Is there a way or type of object that I can use that will share the static memory between plugins? I am using 1.6 in IE. Or am I looking at this wrong and there is an easy way to do this and I am not seeing it.
Thanks,
MarcHi Mylene,
I hope I have understood your problem correctly. I can try to give you a tip. The times I've had to do a pop-up, for instance to show details or a part of the data in a table, I call a javascript function with the required parameters (an ID for details or an array of rows) when the button is pressed or a link is clicked. The function then builds a URL with all the paremeters and uses it to call the standard window.open function. After that the request is handled "as usual", ie as if you didn't actually do a pop-up but simply displayed a new page. The content of the pop-up is a jsp with all the required code to build the table and/or display the data. The contents of the table or data are retrieved with the help of the parameters sent.
I'm not sure if the portal kit provides some kind of standard functionality for this, but in the cases I've worked with J2EE solutions this has been the most common way of solving the problem.
I hope this helps.
kind regards,
Dionisios -
Message bundles accessed from JSF and JSP pages
Hello, everybody!
I'm developing a localized JSF application. It is working pretty well until now.
These are my message files:
mensagens.properties
mensagens_en_US.propertiesThis is how they're configured in faces-config.xml:
<application>
<resource-bundle>
<base-name>br.urca.www.biblioteca.web.mensagens</base-name>
<var>msg</var>
</resource-bundle>
</application>And this is how I access the messages in a page:
<h:outputText value="#{msg.titulo}" />Nothing new until now. But now there was a need for me to have a raw jsp page in
my web application. This page is displaying ok but I also need to access the
message bundles as I'm able to access in the normal jsp with the JSF components.
As you should know I can't use something like the above code with an +<h:outputText>+
to access the messages because this is a JSF component and I'll not be able to use
JSF components with this raw jsp page.
So, my question is: how do I access my localized messages from a raw jsp page? I
suppose there should be a way to do this, but unfortunately I started programming
to the web world in Java with JSF, not JSP, so I don't know how to do this with
JSP.
Thank you very much.

Just include [jstl-1.2.jar|https://maven-repository.dev.java.net/repository/jstl/jars/] in your classpath and define the fmt taglib in your JSP. Nothing more is needed.
Hello, BalusC. Thank you for your help. We're almost there. After I have included the jstl-1.2.jar you provided me I can use the fmt tag and access message bundles from my raw jsp page (even though I had to provide other message bundles instead of the ones that I use in the other jsf pages, but it's better than nothing).
Now there just on problem to be fixed. The jsp page is not aware when I change the locale of my application. I change this locale in a jsf page.
I have this component:
<h:selectOneMenu value="#{pesquisaAcervo.idiomaAplicacao}"
valueChangeListener="# {pesquisaAcervo.idiomaAplicacaoMudado}" onchange="submit();">
<f:selectItems value="#{pesquisaAcervo.idiomasAplicacao}" />
</h:selectOneMenu>that calls this event in my backing bean class:
public void idiomaAplicacaoMudado(ValueChangeEvent e)
fIdiomaAplicacao.liberarItens();
Idioma idioma = Idioma.deString(e.getNewValue().toString());
// This line is for JSF
FacesContext.getCurrentInstance().getViewRoot().setLocale(idioma.localidade());
// This line is for Tiles
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().
put(org.apache.tiles.locale.impl.DefaultLocaleResolver.LOCALE_KEY, idioma.localidade());
}So, do I have to include another line in the idiomaAplicacaoMudado event above in order for the jsp page load the correct resource bundle? Or what else do I have to do?
Thank you.

Request dispatcher and jsp pages called from servlets
Given the following webapp directory structure:
root/
jsp/
..all jsp files
web-inf/
classes/
/servlets
..all servlet files
/com
..all other java class files
I have the jsp directory coded as: jspdir = "/jsp/" (and have tried variations
on this theme)
I try to open a new jsp page with the following code in a servlet in the above
servlet directory:
RequestDispatcher rd;
rd = getServletContext().getRequestDispatcher(jspdir + myjsp.jsp);
rd.forward(req, res);
rd continues to return null.
The jsp pages are not registered in the web.xml file for this webapp, if that
makes any difference.
Does anyone have any suggestions?
[problem.txt]
I create a small sample and put these files into /jsp in my war context
it works fine, please send me the example code you are using and the
environment description of the deployed application
I attached my samples, that work

Can I combine ASP and JSP pages?
Hi all,
Maybe a dumb question...
but Can I have ASP pages in my JSP application?
My problem is as follows:
In the JSP pages of my application, I have some links to ASP application:
http://domain/app.asp
Now IIS is running on another port. But I do not want to go through all my JSP and change the above link to:
http://domain:port/app.asp
Instead any request to http://domain/app.asp should be automatically forwarded to http://domain:port/app.asp
How can this be done? I am using Tomcat as my JSP container.
m_asuActually that is not what I am looking for. I dont want to 'buy' any product. I dont want to deploy ASP application with the JSP application. I just want to redirect the client to another website through an ASP page.
Only catch is that this ASP page needs to sit in my JSP container (Apache Tomcat). Is this possible?

Problems with filters and jsp pages.
I have the following simple filter that checks if there is user information in the session object and redirects accordingly:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class LoginFilter implements Filter
public void init(FilterConfig filterConfig) {}
public void destroy() {}
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
throws IOException, ServletException
System.out.println("filter");
HttpSession session = ((HttpServletRequest)request).getSession();
String action = request.getParameter("action");
if(action != null && !action.equals("login") && !action.equals("wronglogin"))
if(session.getAttribute("username") == null)
((HttpServletResponse)response).sendRedirect("index.jsp?action=wronglogin");
System.out.println("User not OK, kicking out...");
else
chain.doFilter(request, response);
System.out.println("User OK, letting in...");
else
chain.doFilter(request, response);
}The filter is mapped to an admin page with the name index.jsp. However, I get an error for every <% and %> tag in the file (there are quite a few) when I use the filter with the page. The page works fine without the filter, and the filter seems to work with pages without scriptlets (without the <% and %> tags). Here is the beginning of the error report:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 6 in the jsp file: /admin/index.jsp
Generated servlet error:
Syntax error on tokens, AnnotationName expected instead
An error occurred at line: 6 in the jsp file: /admin/index.jsp
Generated servlet error:

An error occurred at line: 6 in the jsp file: /admin/index.jsp

Jasper gives me many errors per <% and %> tag. As you can see there is a <% tag on line 6. Any idea, why this does not work?
Thanks!

chincillyaWhat is the JSP scriptlet code at line 6 ?
By looking at the code we can identify if there are any syntax errors, otherwise we can't really guess what might be the problem. -
Ordinary java class and jsp page
hi i want to use some java class(not javabean ) in my jsp . how do i import them and use them?
You can just import the package into your JSP, and access it like any other class of the Standard Java API that you access.

Hi, I just recently got tag libraries to work and I am wanting to send a dynamic attribute that has a value which is stored in the session. The problem is that I believe that the tag library is processed before the actual jsp code is, and therefore I get something like
<%= someObj.getValue() %> instead of the actual value. Has anyone else encountered this issue and if so could you please recommend some solution(s)?
Here is how I call the taglibg:
<countytaglib:countyList state="TN" selectedCounty="<%= county %>" />
The value ends up being '<%= county %>' instead of the actual value.
Any help is appreciated. Thank you all in advance!
-PVThe required is only if the attribute is required.
For your question's answer the rtexprvalue should only be true.
in the TLD file for the TAG, for every attribute whose
value can be evaluated by the JSP scriptlet put as
follows:
<attribute>
<name>attribute_name</name>
<required>true</required>
<rtexprvalue>true</rtexprvalue>
</attribute>rtexpvalue should be specified to true in case for the
attribute
name you would like something like
<%= user.getFirstName() %>Hope that helps.
