Compiling Servlet problem that uses a JavaBean

I have a servlet that will get data from a JavaBean which is created before in a jsp file. While I trying to compile the servlet I am getting this message:
--------------------Configuration: JDK version 1.3 <Default>--------------------

Process completed.
Where is the problem. SimpleBean is successfully being initializing in my jsp file. But I couldn't compile my servlet that will get data from that bean. Both my servlet and bean are in the same package. I am using JCreator to compile servlets. I think the problem is the compile string that JCreator uses. Can you help me. Thx in advance.

Hi,
The problem is it is not finding the Bean. Put it in the classpath.
The simplest way is put the class in /WEB-INF/classes/MyPackage folder.

Compile a project that uses Spark modules (SDK 4.5) with FB4.1?

Is it possible to compile a project that uses Spark modules with Flash Builder 4.1?
I've added SDK 4.5 to FB and selected it in the project properties (no problems here).
But how about the 'Flex modules' tab in the project properties window, will it be able to add Spark modules to the application?

Yes, you will be able to use s:Module with FB 4. You'll have to do a new MXML component, then go to Flex Modules and click on the add button. (The new module wizard there won't support the spark module)
However, please note that this is unsupported in the sense that we haven't tried that out at our end. (But I personally have and it works )

Problems while compiling a project that uses Database Adapter

Hi,
I am working on a small WebService that uses the Database Adapter to connect with the Oracle-Lite database. The process is a synchronous process which has client and DatabaseService as the partner link. The goal of this project is to get two inputs from the user and send it over to the DatabaseService for it to select the rows from the table based on the inputs sent. The process activity has an invoke function which had two varibles Invoke_1_inputVarible and Invoke_1_outputVarible. I have included the *.xds that contains the database schema. When I compile the project i get the following error
Error(38): [Error ORABPEL-10035]: wrong messageType [Description]: in line 38 of "D:\OraBPELPM_2\integration\jdev\jdev\mywork\Workspace1\Login\Login.bpel", messageType "{http://xmlns.oracle.com/pcbpel/adapter/db/ds/}EmployeeRole_msg" of variable "Invoke_1_dsSelect_InputVariable" does not match the expected messageType "{http://xmlns.oracle.com/pcbpel/adapter/db/ds/}dsSelect_inparameters" in <invoke>. [Potential fix]: make sure the correct variable is used in invoke.
My question is how do I assign correct messageType for the variables.

Looks like an import Problem.
The Compiler is not able to "see" the SimpleBean Class.
Take care of the Classpath and your imports.
Happy Coding. :-)

Problem in compiling servlet class - using Tomcat

Hi,
I have a servlet pgm that I'm trying to compile.I using Tomcat application server.I have my servlet class in D:\servlet_wrk\project1\src
and my deployment descriptor in D:\servlet_wrk\project1\etc
my CLASSPATH var is set to C:\Sun\AppServer\jdk\bin
and
my PATH var is set to C:\Sun\AppServer\bin.
When I compile my servlet class Ch1Servlet.java in the command line from the directory
D:\servlet_wrk\project1 using the command
javac -classpath D:\applications\tomcat-5.5.12\common\lib\servlet-api.jar -d classes src/Ch1Servlet.java,
it says error:cannot read: src/Ch1Servlet.java
Can somebody help me to solve this problem and help me to compile my servlet class.
Thanks.

Thanks...as u said I tried putting dir & found that
my file was saved as Ch1Servlet.java.txt instead for
Ch1Servlet.java......So that was a problem.Now I'm
able to compile.Oh, yeah. Notepad will do that to you. I think when you save in Notepad if you put quotes around the name "Whatever.java" then it won't add the .txt.
But on compiling I'm getting the following error
package java.servlet.* does not exist
package java.servlet.http.* does not exist
package java.io.* does not exist
Do u the reason for this??? The servlet stuff is java[b]x.servlet. For the io stuff, I don't know, I'd have to see your code. Either you have a typo or a corrupt installation.

Problem to connect to mysql from servlet using a javabean

Hi,
I'm new here and beginner on java to.
I have problem to connect to MySql database, by a connection javabean.
It's the following: a HTML page calls a servlet and this servlet imports the package connection javabean.
It has no problem when I establish the connection inside the servlet, with all its methods (public and private). But i want to separate the code connection from servlet.
Detail: there is no problem, using the javabean to connect to MS Access database.
I put "mysql-connector-java-3.1.12-bin.jar" file inside WEB-INF/lib application and common/lib directories.
I set the classpath:
SET CLASSPATH=%CATALINA_HOME%\COMMON\LIB\mysql-connector-java-3.1.12-bin.jar;%CLASSPATH%
I think that the servlet cannot create an instance of javabean, because passed by catch exception of the servlet init method.
But I don't know why.
Please Why?
Below there are the fragment of errors, servlet code e javabean code.
Thank you.

How to use a javaBean in a servlet without FORMS...

Hi,
I would like to use a javaBean in a Servlet.
I know how you can do this with the code
HttpSession session = request.getSession();
in your servlet.
However, by using this code you have to call the servlet by a FORM. Is it possible to call the servlet (which calls the javaBean) in your JSP file without a FORM?
Greetings
Tigi

Thanks Anthony,
I'm working with Tigi on the same project and now I can tell you that the problem is solved.
request.getRequestDisptacher("/myServlet");hehe, you switched the 't' and the 'a'
<%@ include file="/myServlet" %>this is the one we use :)
But what is the difference between the first one and the last one? Now We are using the last one because that's the shortest :) not a pretty good reason huh :)
cheers,
Soep

Problem with HP-UX extended procedures that use C++ Standard library

func(fout);
catch (MyException& ex) {
fout << "xp_nuhash2: caught MyException" << std::endl;

Now, if i use classic C++ (aCC -AP) it works. The trouble is, we have a lot of code that uses the Standard C++ library and we don't have the time to port it back to classic C++.
The problem seems to be with an incompatibility with the standard C++ library. What is the magic potion of linker and/or compiler switches that would enable my extended procedures to use the standard C++ library?
Here is the environment we are using:

Now, if i use classic C++ (aCC -AP) it works. The trouble is, we have a lot of code that uses the Standard C++ library and we don't have the time to port it back to classic C++.
The problem seems to be with an incompatibility with the standard C++ library. What is the magic potion of linker and/or compiler switches that would enable my extended procedures to use the standard C++ library?
Here is the environment we are using:

The use of javabean in a servlet

I used a javabean in (scope=application) a jsp, but now I want to use that bean in my servlet, can anybody show me how?

why not share with others ??
please write out

Problem when using Javabeans in ADF?

Hi,
I encountered a problem when using ADF.
Please look at the following 2 classes :
public class Person
private String name;
private String city;
private int age;
public Person(String name, int age, String city)
this.name = name;
this.age = age;
this.city = city;
public Person()
public void setName(String name)
this.name = name;
public String getName()
return name;
public void setAge(int age)
this.age = age;
public int getAge()
return age;
public void setCity(String city)
this.city = city;
public String getCity()
return city;
public class PersonFactory
public PersonFactory()
public List getPersons()
List list = new ArrayList();
list.add(new Person("peit", 18, "dalian"));
list.add(new Person("robin", 22, "shenyang"));
list.add(new Person("Joe", 30, "York"));
list.add(new Person("Edi", 23, "Beijing"));
return list;
public List getNames()
List list = new ArrayList();
list.add("Peit");
list.add("Robin");
list.add("Joe");
list.add("Edi");
return list;
public void commit()
System.out.println("Data commited");
I created the PersonFactory class as DataControl, so I can use the getPersons() and getNames()(just for test, so they are simple), I drag the names from
the DataControl palette as Table in a JClientPanel, good luck, it works and displays the 4 Strings in a table, but when I drag the persons from
the DataControl palette as Table in the same JClientPanel, it does not work and raises exception :
java.lang.NullPointerException
     at javax.swing.JTable.prepareRenderer(JTable.java:3731)
     at javax.swing.plaf.basic.BasicTableUI.paintCell(BasicTableUI.java:1149)
     at javax.swing.plaf.basic.BasicTableUI.paintCells(BasicTableUI.java:1051)
     at javax.swing.plaf.basic.BasicTableUI.paint(BasicTableUI.java:974)
     So, I confused why? How to edit it properly?
     Thanks.

Hi, Frank
Thank you for your reply.
I am sorry for not explaining well. I mean that the getNames() works fine, but getPersons() does not. The only diferenece between them is the former is simple string and the latter is javabean, but when I made the PersonFactory as DataControl, I set the bean class Person for the getPersons()(list of persons) bean class.
I debuged the class, the exceptions raised when the table for getPersons() setModel() method called.
So, where is the problem?
Thanks.

Problem running Web Service that uses OracleXMLSave on Oracle AS 10.1.3

I am trying to deploy a Web Service that uses OracleXMLSave. The service was built in Jdeveloper 10.1.3 and is deployed to 10gR3 AS. I have all the utitlites available from the 10g Production XML Developers Kit installed . The code compiles and generates correctly . I then deploy to an EAR file that inlcudes the applicaiton code and also all the XDK libraries . No problems so far. But when I run the app, I get an exception like the one below. It says it can't find XMLType . The funny thing is that this library (xdb.jar) and all other related libraries are there in the EAR file . In fact the class loader seems to see it because the exception says that it is there (see text below).
I have added all the libraries from XML Developer kit like xdb.jar , xsu12.jar , etc. I have also verfieid that the files are selected in the WebServices.deploy file and also present in the EAR file . (See full list below the eror message below. ).
It looks like for some reason the class loader can't load the class even though it seems to know that the class exists in the path.
Been sweating on this for a while (probably staring it at too long :) and would really appreciate some help.
This is the exception thrown when the OracleXMLSave Class is called for the first time.

Well I got the EJB lookup working but only when I changed the Provider Url to the pre-10.1.3 format e.g. ormi://someserver:12421/someapp and used jazn.com/oc4jadmin as the username. After reading the online documentation, I didn't think this should work!
Another issue I am having is casting a datasource returned from a JNDI lookup for a datasource. We used to do the lookup in the code and cast to an OracleDataSource. Now it is throwing a class cast exception to ManagedDataSource. Is there a quick and easy solution to this? I really don't want to have to go into the code and change this cast so it'd be great if we can get this working without changing code. This code has been working in a prod environment for two years now on 9.0.3 -> 9.0.4...

I have a problem compiling servlets bymeans of NetBeans IDE 3.6.

If I compile a servlet by means of another IDE, they are oK and work well with NetBeans too.
On the contrary, if I compile it bymeans of Netbeans 3.6, I get a .class which does not work. I
have realized also that for instance if the .class i get with the other IDE is 1,58 KB, if I use
NetBeans I get a .class smaller, that is 1,53 Kb.
Can you help me?
Thanks
Eugenia Mariani

ok
This is the servlet named Contatore.java
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Contatore extends HttpServlet
private int conta;
public void init(ServletConfig config) throws ServletException
conta = 0;
public void doGet(HttpServletRequest richiesta, HttpServletResponse risposta)
throws IOException, ServletException
conta++;
risposta.setContentType("text/html");
PrintWriter out = risposta.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Pagina con contatore</title>");
out.println("</head>");
out.println("<body>");
out.println("Questa pagina e' stata visualizzata");
out.println("<h1>"+conta+ "</h1> volte.");
out.println("</body>");
out.println("</html>");
out.close();
Before using the compiler of NetBeans (that is after getting Contatore.class by means of Bluej) when I use Execute I see in Internet Explorer 6.0 with win Xp Pro at the
http://localhost:8084/esempi/Contatore
Questa pagina e' stata visualizzata
1
volte.
and Contatore.class is 1,58 KB
After that I use the compiler of NetBeans when I use Execute here the error from Tomcat 5.0
I see in Internet Explorer 6.0 with win Xp Pro at the
http://localhost:8084/esempi/Contatore
HTTP Status 404 - Servlet Contatore is not available
type Status report
message Servlet Contatore is not available
description The requested resource (Servlet Contatore is not available) is not available.

and Contatore.class is 1,53 KB
I hope to have said everything
I wait a help, please.
Thanks

Example Servlets that use JAXM?

OK, maybe I missed a chapter in the JWSDP tutorial but I'm trying to develop a servlet that uses JAXM to process a soap request, and I can't find any examples of how to do this. There are a number of client code examples, but nothing for the server side. There is no source code for the "ReceivingServlet.class", which I believe does what I am loooking for.
BTW, I know that I can do it easily using JAX-RPC, but I specifically want to do it using JAXM.
Any ideas or suggestions?
Thanks,
Frank
