JSP page import problems

Hi,
i've got a problem with importing java classes into my jsp file. i use the following method:
<%@ page import="Person" %>
Person is originally a selfwritten class which lies in the subdirectory WEB-INF/classes of my webapps directory of my tomcat server. when i use the above method i get the following error output:
org.apache.jasper.JasperException: Unable to compile class for JSP An error occurred at line: 125 in the jsp file: /ShowPersonsView.jsp Generated servlet error:

Thus, the Person class can not be found but i dunno why. Where do I have to make an entry? I already tried to set a classpath to this file, but it doesn't work. Has anyone an idea?
Thanx

Put the class in a package and call it accordingly. Example:
WEB-INF
   |
    --- classes
           |
            --- example
                   |
                    --- Person.java
//then in Person add:
package example;
//and in jsp
<%@ page import="example.Person" %>

JSP page import directive

I'm running JSPs and servlets under Netscape (Tomcat) web server and am getting errors with my jsp file's first line:
[%@page import="java.util.*, myclass" %]
Netscape server throws an error saying that it can't import myclass. I've put the myclass.class file in various locations in the server but it still can't find it. Does anyone know a foolproof way to make the server find such a class when it's compiling jsp's?
Thanks,
David

I think you have to specify package name of your class & not your calss name.

CR for Eclipse version 2.0.1 Report JSP page display problem

I create report and Report viewer JSP page. When i run JSP page I meet with this [screen|http://www.sendspace.com/file/r2ys55]. When I select print preview the [screen|http://www.sendspace.com/file/4661oa] like this.
I use CR for Eclipse all in one pack 2.0.1.
Anyone know what is the problem ?
Any help would be greatly appreciated.
Thanks;

Yes, we are. We have to set the password unless there is a way to save the password in the report. The CR designer always asks for the password. Is there away to save the password in the report from the designer?
Do you have an ETA on the bug fix?
It is good to know the problem is being looked into.

Tomcat wants to see a ".", because as of jdk 1.4, you can no longer import packageless (i.e 'default package') classes. So put your class in a package. It is also good programming practice.

Hi Pawan,
Thanks for your information. It was problem with my pom.xml It started to work after changing my POM.xml
I am not able to get sling service for TestServiceImpl. But I am only able to create TestService which is my interface. I need to get reference for TestServiceImpl class not for TestService interface. Please help me to make it.
i have created TestServiceImpl and TestService class for testing whether my bubdle is crating all the folder structure or not.
But my requirement is like assume class A has some methods like getMenuLink, setMenuLink.. And In class B i am calling some methods in class A and doing some manipulation in createLink method.
Here class B does not have any interface. Not implementing any interface. But I need to get class B refererence via sling.getService.
I know that if we are using maven SCR plugin..we need to have @component, @service. And All java classes are not services. Will it work if I add activate, deactivate method in class B?
Could you please tell me how to proceed next?
Thanks,
Anderson

Weird error. Never seen this one before.
Try packaging your classes eg:package myClasses;and import them:<%@page import="myClasses.*"%>Should fix the problem.

Does anybody know the solution to this problem
Any kind of help will be highly appreciated.

Hi Adam Winer,
I want to try your solution.
just wanted some more clarification .....
So, let's say you have:
DWStaticJSP.jsp: plain JSP
report_palm.jsp: JSF JSP included by DWStaticJSP.jsp
What you should do is use an URL of:
/faces/DWStatic.jsp
to access the outer plain JSP (yes, even though it's not really a faces page), and then have
/faces/DWStatic.jsp include just plain /report_palm.jsp.
In essence, the critical thing is that the FacesServlet wraps the entire request - FacesServlet cannot run
for just a piece of the request.My question is where should i store the DWStatic.jsp file ... As u said i should acces it using /faces/DWStatic.jsp do i need to save it in the faces folder or just in the web app root.
I cant save the DWStatic.jsp in the faces folder as this file is used for lot of different purpose in my company application.
So can u give me a solution where in i can keep the DWStatic.jsp in the web-root folder and still try your solution
Also is this the right setting for facesServlet in the web.xml.
<servlet>
<servlet-name>FacesServlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>FacesServlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
Whatever follows below this line is the describtion of the web appp structure which i have in my company.
We have an application where in all the jsp files are stored in the web-app root folder.....
I will be using alphabets like a.jsp ... b.jsp .... to keep the explanation small...
I have an a.jsp file which includes a b.jsp file which in turn includes a c.jsp......
Now we have started using JSF.....
Now as a developer .... i want the c.jsp to include a d.jsp file which contains JSF components...
The thing is i cant change the location of a.jsp, b.jsp and c.jsp......
Can u tell me how i should call " a.jsp" ... imean the url so that the "d.jsp" file gets processed properly.
Also where should i save all the jsp files and what config is requiered in the web.xml for your solution
I thank you for your help

JSP Shopping Cart problem

Hello,
I'm writing a JSP page with a shopping cart so the user can add products to it, nfortunately the thing won't work.. I keep getting an NullPointerException.. I'm probably screwing up somewhere.. I would be very thankful if you could help me out..
this is the code for the Shopping Cart Bean:
[myCart.java]
package myCart;
import java.util.*;
public class myCart implements java.io.Serializable{
     private Vector items;
public String[] getItems(){
     String strTemp[] = new String[items.size()];
     items.copyInto(strTemp);
     return strTemp;
public void setItems(Vector newItems){
     items=newItems;
public void addItem(String newId){
     items.addElement(newId);
This is the JSP page that I'm using:
[myCart.jsp]
<%@ page import="java.sql.*" %>
<%@ page import="java.util.*" %>
<jsp:useBean id="myCart" class="myCart.myCart" scope="session" />
<%
Connection con;
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection("jdbc:odbc:produkten");
Statement stmt = con.createStatement();
     ResultSet rs = stmt.executeQuery("SELECT * FROM tblProdukten WHERE NR= "+request.getParameter("nr")+"");
while (rs.next()) {
     String merk = rs.getString("MERK");
     long temp = rs.getLong("NR");
     String nr = Long.toString(temp);
-----> myCart.addItem(nr);
     %>
     <BR>Nr     : <%=nr%>
     <BR>test :     <%=merk%>
     <HR>
<% } %>
<%
     con.close();
     catch(ClassNotFoundException cnfex)
          out.println("jdbc odbc driver not found // muzz");
     catch(SQLException sqlex)
          out.println(sqlex);
%>
</TABLE>
</BODY>
</HTML>
I think I probably(??) put the <myCart.addItem> in the wrong part of the code..??
Greetings,
Michael

yes, I see, I forgot to initiate that, I'm still
learning so please bare with me :)
I now initiated the <items> vector like this:
Vector items = new Vector();
and added this:
myCart.items.addItem(nr);
But it still won't work correctly >>
First error: Your Vector items is not a public variable. Therefore, outside classes will not be able to access it. No problem though, you have a method to take care of that. Instead of what you're doing, simply call
myCart.addItem(nr)This calls the public method addItem(String) which accesses your private Vector items, and adds a string to the vector.
Your second error should be taken care of. It is resulting from the fact that instead of calling the method addItem() from teh class instance, youre trying to access the Vector items first, and then trying to call addItem() from that... not only can you not access that variable, as stated above, but there is no method in Vector called addItems(). You could conceivably make items public, but I'd stick with what you've got.

JSP TableView Sorting Problem

I have been trying to get a tableview to be sortable by clicking on the header of columns. I have been reviewing existing threads on the forum in particular the one below.
https://forums.sdn.sap.com/thread.jspa?threadID=16417
I seem to understand the concept but for some reason my table does not sort, it just does nothing. Could someone take a look and see if you can find any problems - I can't wait to give points.
Here is all my code.
Here is the Java....
package MSSPackage;

Any help would be greatly apprciated and rewarded...

Hi Don,
be aware that after the method onHeaderClick(Event event) is executed the method doProcessBeforeOutput() is executed as well.
I look over your code and found the following:
1) In method onHeaderClick you sort the table model and store the table model in the bean
2) In method doProcessBeforeOutput() you create a new table model from scratch (in helper method tableViewFormat())and store it in the bean. Thus you overwrite the sorted model.
I suggest that you move the initial creation of the table model in method doInitialization(). Do not forget to store the created table in the bean. In method doProcessBeforeOutput() you retrieve the table model from the bean instead of creating a new one for every request.
Best regards,
Martin

The only times I see this is when the classes are not in the right place. What you describe should be the right place, but I am guessing that something more complex is happening...
Are you using an IDE to run the Server? Are you sure that you have exactly one instance of Tomcat installed on your computer? Do you have a context.xml or <Context ...> element in the server.xml that tells the server to look somplace else for files?
My suggestions would be to shut down tomcat, go to <TOMCAT_HOME>/webapps, make a new .jsp (by text editor, not IDE) that does the include and some simple output. Use the command line to start Tomcat (so you can be sure of how it is starting) and see what happens.
Make sure you read your log files. It could be that if you have a problem with either the context or web.xml that your context is not starting properly... hopefully that would be logged.

How to use Session scope in jsp page

Hello, I have login form, where user provides username and password. Then click on submit, it will forward to validation.jsp. Where it will check in database make sure username and password exit. Now i can also retrive accountid of perticular user. I want to put that username and accountid in session scope. so all other pages can use that username and accountid. How can i do that. I'm new at this, so please provide me example too. Here is my code for login.jsp and validation.jsp..
Validation.jsp
<%@ page import="java.util.*" %>
<%@ page import="java.sql.*" %>
//String name = request.getParameter( "username" );//
//session.setAttribute( "accountID",accountID );//
<%
String connURL = "jdbc:oracle:thin:@orca.csc.ncsu.edu:1521:ORCL";
     Connection conn = null;
     Statement stmt = null;
     ResultSet rs = null;
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
conn = DriverManager.getConnection(connURL, "vapatel","pjdas");
stmt = conn.createStatement();
String user=request.getParameter("userName");
String password=request.getParameter("password");
boolean entrance=false;
stmt.excuteQuery("SELECT AccountID From Password WHERE USERNAME='"+user+"'");
rs = stmt.executeQuery("SELECT * FROM Password WHERE USERNAME='"+user+"' AND PASSWORD='"+password+"'");
while(rs.next()){
String dbUser = rs.getString("USERNAME");
String dbPassword= rs.getString("PASSWORD");
if ((user.equals(dbUser)) && (password.equals(dbPassword))){
entrance=true;
if (entrance==true){%>
<jsp:forward page="form.jsp"/>
<%}

hi,
to put something into session scope in a jsp page use:
session.setAttribute("counter", Integer.toString(5));to retrieve is from a jsp page use:
String counterAttribute = (String)session.getAttribute("counter");

How to use java class in jsp page of JSPProvider?

Hello everybody.
I created simple JSPProvider channel with portal amconsole and named it "jspprov1". Then I created "jspprov"1 directory under "/ets/opt/SUNWps/desktop/sampleportal". I put "index.jsp" in it. And it worked until I add this line into "index.jsp": <% @page import="jspprov1package.aclass1" %>. Then I created directory "jspprov1package" under "/ets/opt/SUNWps/desktop/classes" and put "aclass1.class" into it and into "/ets/opt/SUNWps/desktop/classes" itself. I created "aclass1.class" on the other machine (with no installed portal) in j2sdk1.4.1_02: "javac aclass1.java". The text of this class is simple:
"package jspprov1package;
public class aclass1{
public int int_field = 10;
But the page still don't work. It writes on the portal desktop "ERROR: Content is not available".
Does anybody know why this happened?

Sorry, there were mistakes in jsp page and java files.
I maked the channel "show exceptions" and found them out.

Render a JSP page into HTML in a String

I am using a mail template system that gets templates as JSP pages placed in /WEB-INF/mailtemplates/
I want to internally parse JSPs as if they were real JSPs in my tomcat but:
- Get get them using getResourceAsStream (or any other way)
- make JSP engine translate JSP into HTML into a String object.
- Send a mail with this HTML. (this part is already finished)
What I need is a method with the following proposed signature:
public String getMailTemplate(java.io.InputStream jspPageStream, javax.servlet.HttpServletRequest request) {}
The method must get the JSP from the stream, render it into the HTML and return it as a String.
Of course, it must render the JSP as a real JSP, using the apserver JSP engine. It must so replace any tags and EL objects:
${session.user.name} -> The name of the user
<c:forEach, ...
etc. etc. etc.
�Any ideas / directions on how to achieve this?
thanks,
Ignacio

Ok, just tried it out myself, and I'm getting the same result you are.
Nothing makes it out to the RedirectingServletResponse.
It appears to be buffering it somewhere in the included page.
If you put a command to flush the buffer on the jsp page being included: <% out.flush; %> then it works.
So why doesn't it work normally? Why doesn't the call to requestDispatcher.include (or forward) flush/commit its response?
I will admit to being stuck on this one. I'm figuring its something in the internal workings of Tomcat/JSP to do with when a page is flushed or not, but I can't thing of anything right now.
Here is the test I put together to try this out (along with a few corrections to my previous code). I will admit to being stumped :-)

        super(response);
        this.out = new RedirectServletStream(out);
