Cannot find java classes in PDK

we cannot find the java.classes
oracle.webdb.portlet.Portlet;
oracle.webdb.portlet.PortletInfo;
oracle.webdb.portlet.PortletUtils;
we need them for developing portlets.

CDR-17066 RON cannot find java EWT graphics classes

Hello,
I am evaluating Oracle SCM. Everything's going great, except I am unable to use the Version History or Version Events. When I try, I get an error:
"CDR-17066: RON cannot find java EWT graphics classes"
The action it recommends is to check the registry or environment variable JVM_CLASSPATH_RON, and make sure it points to the ewt jar.
I found a jar called ewt3.jar in my oracle/jlib directory. There was no environmental variable called JVM_CLASSPATH_RON, so I created one and set it to that jar. But I'm still getting the same error.
Any help would be appreciated. Thank you.

Hi,
this error message is rather strange: I checked in our knwoledge base, but you seem to be the first one having this issue!
I had a look to my registry and indeed I couldn't find the variable JVM_CLASSPATH_RON.
I suspect that this variable was superseded by another one (JVM_CLASSPATH_DEFAULT_THIN_JDBC ?).
I checked for all variables including ewt and found the following:
. FORMS90_CLASSPATH (<Home>\jlib\ewt3.jar)
. FORMS90_BUILDER_CLASSPATH (<Home>\jlib\ewt3.jar)
. JVM_CLASSPATH_DEFAULT_THIN_JDBC (<Home>\jlib\ewt4.jar)
FORMS90_... variables are not used by the Version History and Version Event Viewers, but JVM_CLASSPATH_DEFAULT_THIN_JDBC is.
I removed the entry <Home>\jlib\ewt4.jar from JVM_CLASSPATH_DEFAULT_THIN_JDBC, and then I could reproduce your issue.
So could you check the content of this variable JVM_CLASSPATH_DEFAULT_THIN_JDBC?
It's located in HKEY_LOCAL_MACHINE\SOFTWARE\Oracle\HOMEx\REPADM61\DEFAULT_JVM_PARAMS_THIN_JDBC
Could you also check that file <Home>\jlib\ewt4.jar does exist on your machine?

Didier.

I already created the data source and JNDI Name in the DBAdapter but still getting the error while deploying the application.
One mistake that i think i have made after creating the data source now the DBAdapter.rar file taking the path as follows.
Source Path: C:\ Oracle\ Middleware\ Oracle_SOA1\ soa\ connectors\ was\ DbAdapter. rar
Deployment Plan: C:\ Oracle\ Middleware\ Oracle_SOA1\ soa\ connectors\ was\ Plan. xml
initially the path was as follows:
Source Path: C:\ Oracle\ Middleware\ Oracle_SOA1\ soa\ connectors\ DbAdapter. rar
Deployment Plan: C:\ Oracle\ Middleware\ Oracle_SOA1\ soa\ connectors\ Plan. xml
Please help me i have googled a lot but can't find the answer anywhere.
Thanks in advance

Mate ,
Just check the health status and state of DB Adapter in the deployments of WLAdminConsole.
If its inactive , redeploy and update it ,also make sure its targeted to the right server.

"cannot find symbol : class Scanner" error message

I have an error message that says:
"cannot find symbol : class Scanner"
I tried typing at the top of the program
import java.util.Scanner;but I still have the same error message.
What should I do ?
Thank you in advance

http://java.sun.com/j2se/1.5.0/docs/api/java/util/Scanner.html
Since:
1.5
look at the javadoc, it says since 1.5 so it's not there in earlier versions.
just a guess

For a beginner these tools are worst, because they
hide all the stuff a programmer needs to know to find
his way around Java. They should spend a few weeks
with the command line and a good text editor before
switching.
Just because an IDE does something for you, it
doesn't mean you don't need to kno wwhat it does.
Unless you volunteer to handle all "how do I do X in
Netbeans/Eclipse/Whatever", JAR and classpath
questions posted here by newbies yourself.I suppose I can agree with that to some extent. I wouldn't suggest to anyone that they just blindly trust whatever code the IDE inserts automatically.
But there's nothing wrong about learning by example. The IDE is willing to teach proper syntax, and eclipse will give suggestions about capitalizing class names and making constants all-caps.
There are things that frustrate new programmers where an IDE will be helpful, especially if the entire API is uncharted territory.

Servlet cannot find helper class

Hello
Under WEB-INF/classes I put ServletExample and SingletonExample. Compiling ServletExample, that makes use of SingletonExample, works.
In the directory WEB-INF/classes I also have another direcotry, test. And in WEB-INF/classes/test I put again ServletExample and SingletonExample.
Here I have tried in several ways to compile the servlet, but I always get an:
Cannot find symbol class SingletonExample.
I tried writing package test at the top of both files, and even at the top of only one of these two.
I even tried to make WEB-INF/classes/test/ServletExample make use of SingletonExample residing in WEB-INF/classes, but I didnt succeded.
What happens when you have subdirectory in WEB-INF/classes/? I think this is a MUST, to have subdirectory in large webapplication, so I really dont want to put everything in the classes directory.
Do you how to resolve this prolem? And: if Im in WEB-INF/classes/test and want to referr from a servlet residing in this direcory to a Singleton/helper class residing in WEB-INF/classes/, which approach do I have to use?
Thanks
Paolo

Jeez, you aren't gonna get very far in Java like this.
CLASSPATH is wrong - again. You're supposed to give JARs and paths where the class loader is supposed to look, not the actual .class file.
Also, you're not telling the compiler to put the .class file in the package directory structure.
Your example is pretty awful. Try this:
Put this code into c:\common
package common;
import common.test.TestDown; // What the hell is this? There is no package test, but there is a package named common.test
public class TestUp
   public void sayHello()
      System.out.println("Hello.....");
}Put this code into c:\common\test
package common.test;
import common.TestUp;
public class TestDown
   public TestDown()
        TestUp testUp = new TestUp();
        testUp.sayHello();
   public static void main(String[] args)
        new TestDown();
}Open a command shell and navigate to c:\, then do the following:
Directory of c:
07/01/2005 03:43 PM    <DIR>          .
07/01/2005 03:43 PM    <DIR>          ..

Cannot find the class file

Hi All,
Can any one help me regarding the issue?
Error:
package com.support.misc.feedback
I am getting the following error for the above line. But I have created the Hierarchy in folder structure. But still it is throwing the error.
1. Cannot find the class file for com.sapportals.htmlb.page.DynPage
2. This compilation unit indirectly references the missing type com.sapportals.htmlb.page.DynPage (typically some required class file is referencing a type outside the class path) FeedbackBean.java
Thanks in Advance.
Message was edited by: Gowsika Kannan

Hi Gowsika,
the class needed is located in htmlb.jar which can be found under <irj-root>/WEB-INF/portal/portalapps/com.sap.portal.htmlb/lib
You need to integrate this jar in your .classpath
Hope this helps,
Robert

Wrapper cannot find servlet class error

I'm curious. Could you strip off the "java." part of the package, so both in your sourcefile as in the directory structure? It may be that the java package is not allowed, but then I wouldn't know why you didn't get a compile error...

"cannot find this class" erro while creating Background Callable Object.

Hi All,
I am facing "cannot find this class" while creating Background Callable Object.
I followed the following document for Creating Background Callable Object.
[Creating Callable Objects for Background Execution|http://help.sap.com/saphelp_nwce10/helpdata/en/53/cde385301f4aa3b8e77a92cd46bff3/frameset.htm]
After giving the fully qualified java class name in the Implementation Class Name when i press next i am getting the error.
Please suggets me in solving this issue.
Regards,
S.V.Satish Kumar
Edited by: Sathish Kumar SV on Apr 4, 2009 10:34 AM

Hi, kavita.
First, make sure you choosed the correct container when you created the background CO.
Second, make sure your package name was "com.examples.bckgco" and class name was "UserDetailsCallableObject". The exception which you got just means you entered incorrect name.
It doesn`t relate to your program.
Best Regards.
Louis Huang.

Cannot find servlet class

I have a new computer and I have installed the latest version of Tomcat but kept the old free version of the Sun One Studio which I still had a setup file for (as I couldn't find it on this site anywhere for free anymore). The new version of Tomcat puts my webapps in a different area now being s1studio\tomcat401\webapps but there is another area for the server: C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\tomcat-docs. I use the first directory and that shows my jsp's etc but it doesn't find my servlets.
My problem I am having is that my log file is showing this:

and so it goes on.
My classes are in the directory as:
C:\Program Files\s1studio_jdk\s1studio\tomcat401\webapps\ROOT\servervirtualward\WEB-INF\classes\virtualward\java
and my web.xml is here: C:\Program Files\s1studio_jdk\s1studio\tomcat401\webapps\ROOT\servervirtualward\WEB-INF
and the code for the CourseList servlet is:
<servlet>
               <servlet-name>virtualward.java.CourseList</servlet-name>
               <servlet-class>virtualward.java.CourseList</servlet-class>
       </servlet>
<servlet-mapping>
               <servlet-name>virtualward.java.CourseList</servlet-name>
               <url-pattern>/servlet/CourseList</url-pattern>
   </servlet-mapping>The example servlets work fine and all .jsp's work within my project.
Can anyone spot what's wrong?
Thanks!!!

I did a basic .jsp page and that worked so at least that's something. Here is my code for the .jsp that won't work. It worked perfectly on my old computer on the configuration with Tomcat4
<%@page import="virtualward.java.Student"%>
<jsp:useBean id="student" class="virtualward.java.Student" scope="session"/>
<%
String error = null; // set the error message to null for the initial visit
                    //to the page
if (request.getParameter("SUBMITTED") != null)
    Student s = Student.findStudent(request.getParameter("userid"));
    if (s == null)
        error = "Login ID not found, please try again.";
    else
        //if the input password = the stored password
        if (request.getParameter("userpword").equals(s.getPWord()))
            //if login priviledges are 1 give them student access
            if (s.getPrivilegeLevel()==1)
                //store the details of that students details in a session from the object.
                session.setAttribute("student", s);
                //go to the page to display the details
                response.sendRedirect("stuProfile.jsp");
            } //if login priviledges are 2 or 3 direct them to a page that
              //gives them Lecturer priviledges
            else if (s.getPrivilegeLevel()==2 || s.getPrivilegeLevel()==3)
                    //store the details of that students details in a session from the object.
                    session.setAttribute("student", s);
                    //go to the page to display the details
                    //response.sendRedirect("selectProfile.jsp"); //old link
                         response.sendRedirect("maintenance/courseIdenti.jsp");

Thanks for your reply, can I ask if my setup is correct ?
I'm using Eclipse, on my left in Dynamic Web Perspective I have Servers and myProject.
In myProject ->Java Resources:src (this is where all my java files are with package) and WebContent.
In WebContent ->META-INF and WEB-INF
In WEB-INF ->(this is where I have lib folder and my xml & jsp files)
In lib I have Oracle connector .jar
Can someone confirm if this is the right setup please.
thanks
Zed

Cannot find symbol class Scanner

hi all
i'm defining a class within a project so i can use the class inside my program, but the line:
Scanner keyboard = new Scanner(System.in);generates an error with my compiler:
cannot find symbol class Scanner
please help

you aren't using jdk 5 or higher then. that's when scanner was added to the jdk.
download a modern jdk and you'll be fine.
