Error(86,88): incompatible types; found: java.util.ArrayList

Hi,
I'm getting following error :
Error(86,88): incompatible types; found: java.util.ArrayList, required: com.sun.java.util.collections.ArrayList
The line JDev is complaining about contains the following code :
com.sun.java.util.collections.ArrayList runtimeErrors = container.getExceptionsList();
I really don't have a clue where this error comes from. If I right-click on ArrayList it brings me to the correct declaration.
Does somebody know what I'm doing wrong?
Thanks in advance for you help!
Kris

Kris,
try changing the code to :
java.util.ArrayList runtimeErrors = container.getExceptionsList();apparently container.getExceptionsList() returns a java.util.Arraylist not a com.sun.java.util.collections.ArrayList
HTH,
John

var props = javafx.util.Properties {};
props.load(input);
input.close();

Please suggest some solution.
Thanks in advance.

Incompatible types - found java.lang.String but expected int

This is an extremely small simple program but i keep getting an "incompatible types - found java.lang.String but expected int" error and dont understand why. Im still pretty new to Java so it might just be something stupid im over looking...
import java.io.*;
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
public class Lab
public static void main(String []args)
int input = JOptionPane.showInputDialog("Input Decimal ");
String bin = Integer.toBinaryString(input);
String hex = Integer.toHexString(input);
System.out.println("Decimal= " + input + '\n' + "Binary= " + bin + '\n' + "Hexadecimal " + hex);
}

You should always post the full, exact error message.
Your error message probably says that the error occurred on something like line #10, the JOptionPane line. The error is telling you that the compiler found a String value, but an int value was expected.
If you go to the API docs for JOptionPane, it will tell you what value type is returned for showInputDialog(). The value type is String. But you are trying to assign that value to an int. You can't do that.
You will need to assign the showInputDialog() value to a String variable. Then use Integer.parseInt(the_string) to convert to an int value.

Incompatible type found

Gurus,
I'm getting the following error and hope you could help. It's complaining about code in my AM (in bold). Any ideas?
Error(281,41): incompatible types; found: oracle.jbo.Row, required: acctmap.oracle.apps.spl.am.server.UserRespVORowImpl
AM code:
UserRespVOImpl reqVO = (UserRespVOImpl)findViewObject("Sysadmin");
if(reqVO!=null)
Integer userid = new Integer(tx.getUserId());
reqVO.initUserRespVO(userid);
reqVO.reset();
UserRespVORowImpl row = reqVO.next();
String priv = (String)row.getSysadmin();
VO code:
public void initUserRespVO(Integer txUserId)
setWhereClauseParams(null); //Always reset
setWhereClauseParam(0,txUserId);

}

Hi Sreese,
Change your code to ...
reqVO.reset();
UserRespVORowImpl row = *(UserRespVORowImpl)* reqVO.next();
String priv = (String)row.getSysadmin();
Thanks

As already pointed out, there is no way to specify a generic type in a tag library descriptor. You may however specify an Object type in your tld and still have the variable in your tag as a parameterized generic type.
In your tld change the type to Object.
<type>java.lang.Object</type>.
The properties tag itself needs no change and can continue to use parameterized types.

Newbie help with collection java.util.ArrayList

Hi,
the documentation for the class ArrayList is given as
public class ArrayList<E>
extends AbstractList<E>
what is that <E> over there ? Similarly, what is the <T> in an iterator ? Exact problem along with code is at the end of the post.
I am a C++ programmer and am very comfortable with the STL, but that approach i.e. ArrayList<Job> does not work over here :(
PLease help.
TIA,
Madhu.
Code Details:
I have a class (Job) which I wish to add to the list using the add method. Obviously, it gives an error.
Code goes as
class MyQueue extends java.lang.Object
private java.util.ArrayList jobsList=new java.util.ArrayList(100);
public void addtoMyQueueatIndex(Job newJob,int Index)
jobsList.add((java.lang.Object)newJob,Index);
Error is :
MyQueue.java:96: cannot find symbol
symbol : method addtoMyQueueatIndex((java.lang.Object,int)
location: class java.util.ArrayList
jobsList.add((java.lang.Object)newJob,Index);

Are you using J2SDK 1.5.0 beta 1 or J2SDK 1.4.2? Are you using the docs from 1.5 and the compiler from 1.4.2?
private java.util.ArrayList jobsList=new java.util.ArrayList(100); //-- 1.4.2 code
private java.util.List<Job> jobsList = new java.util.ArrayList<Job> (100); //-- 1.5.0 code (preferred style)
private java.util.ArrayList<Job> jobsList = new java.util.ArrayList<Job> (100); //-- 1.5.0 codeAs a matter of style, use the interface and not the real class when declaring a variable like the jobsList above whenever possible or applicable.
You do not need to cast the object newJob to Object. And you have inverted the positions of the parameters.
void add(int index, E element)
Inserts the specified element at the specified position in this list (optional operation).
jobsList.add(Index, newJob);

You were using the ReflectionPofSerializer coded by Alexey. If you are pretty sure that the object you retrieved was stored using the same serializer, might want to contact Alexey to see if he can help you out.

Question on import java.util.ArrayList, etc.

Hi,
I was wondering what the following meant and what the differences were. When would I have to use these:
import java.util.ArrayList;
import java.util.Collections; <--I especially don't understand what this means
import java.util.Comparator; <---same for this (can I consolidate these into the bottom two?)
import java.io.*;
import java.util.*;

MAresJonson wrote:
Also, what does this mean:
return foo == f.getFoo() ? true : false;
(more specifically...what does the "? true : false" mean and is there another way to code that?)It's called the ternary operator. For your specific example, you could just do:
return foo == f.getFoo();But, more generally,
return foo == f.getFoo() ? "equal" : "Not equal";means:
if (foo == f.getFoo()) {
return "equal";
else {
return "Not equal";
}As everyone else said at the same time...

Error while deploying a web service whose return type is java.util.Date

Hi
I have written a simple web service which takes in a date input (java.util.Date) and returns the same date back to the client.
public interface Ping extends Remote
* A simple method that pings the server to test the webservice.
* It sends a datetime to the server which returns the datetime.
* @param pingDateRequest A datetime sent to the server
* @returns The original datetime
public Date ping(Date pingDateRequest) throws RemoteException;
The generation of the Web service related files goes smoothly in JDeveloper 10g. The problem arises when I try to deploy this web service on the Oracle 10g (10.0.3) OC4J standalone. it gives me the following error on the OC4J console :

I read somewhere that the conversion between java to xml datatype and vice versa fails for java.util.Date, so it is better to use java.util.Calendar. When I change the code to return a java.util.Calendar then the JDeveloper prompts me the following failure:
Method Ping: the following parameter types do not have an XML Schema mapping and/or serializer specified : java.util.Calendar.
This forces me to return a String data.
I would appreciate if someone can help me out.

Hi
I got the web service working with some work around. But I am not sure it this approach would be right and good.
I started altogether afresh. I did the following step :
1. Created an Interface (Ping.java) for use in web Service as follows :
public interface Ping extends Remote{
public java.util.Date ping(java.util.Date pingDateRequest)
throws RemoteException;
2. Implemented the above interface in PingImpl.java as follows :
public class PingImpl implements Ping
public java.util.Date ping(java.util.Date pingDateRequest) throws RemoteException {
System.out.println("PingImpl: ping() return datetime = " + pingDateRequest.toString());
return pingDateRequest;
3. Compiled the above 2 java files.
4. Generated a Stateless Java Web Service with the help of JDeveloper. This time the generation was sucessful.(If I had "java.util.Calendar" in place of "java.util.Date" in the java code of the above mentioned files the web service generation would prompt me for error)
5. After the generation of Web Service, I made modification to the Ping interface and its implementing class. In both the files I replaced "java.util.Date" with "java.util.Calendar". The modified java will look as follows :
Ping.Java
=========
public interface Ping extends Remote{
public java.util.Calendar ping(java.util.Calendar pingDateRequest)
throws RemoteException;
PingImpl.Java
================
public class PingImpl implements Ping
public java.util.Calendar ping(java.util.Calendar pingDateRequest) throws RemoteException {
System.out.println("PingImpl: ping() return datetime = " + pingDateRequest.toString());
return pingDateRequest;
6. Now I recompile both the java files.
7. Withour regenerating the Web Service I deploy the Web Service on OC4j 10.0.3 from JDeveloper. This time the deployment was sucessful.(The Deployment fails if I don't follow the step 5.)
8. Now I generated a Stub from JDeveloper and accessed the stub from a client. It works fine. Here if you see the Stub code it takes java.util.Date as a parameter and returns a java.util.Date. (Mind you I am accepting a java.util.Calendar and returning the same in my Web Service interface. Step 5)
The confusing thing is the Serialization and Deserialization of Data from Client java data to Soap message and Soap message to Server java data.
From Client to SOAP :
java.util.Date to datetime
From SOAP to Server :
datetime to java.util.Calendar
From Server to SOAP :
java.util.Calendar to datetime
From SOAP to Client :
datetime to java.util.Date (I am not able to understand this part of the conversion)
Any help or inputs would be appreciated.
Thanks

Tomcat error when run through Eclipse IDE :- java.util.MissingResourceExcep

Friends,
I get the following error while running the tomcat from my eclipse IDE(com.sysdeo.eclipse.tomcat_3.2.1) .
If i try running my tomcat with an application through the command line , it runs fine .... can anybody please guide .?
The error is as follows :-
[b]
Can't find bundle for base name EnvironmentResources_XXXXLocalhostDev, locale en_GB
java.util.MissingResourceException: Can't find bundle for base name EnvironmentResources_XXXXXxLocalhostDev, locale en_GB

Putting the driver into [TOMCAT]/common/lib is sufficient.
The error I think is not related to finding the driver, but actually not retrieving the correct connection string info.
I never had much luck putting this definition info into server.xml
I have had success putting it into a custom context.xml file for a web app as described [url http://tomcat.apache.org/tomcat-5.5-doc/config/context.html]here
in individual files (with a ".xml" extension) in the $CATALINA_HOME/conf/[enginename]/[hostname]/ directory. The name of the file (less the .xml) extension will be used as the context path. Multi-level context paths may be defined using #, e.g. context#path.xml. The default web application may be defined by using a file called ROOT.xml.
eg [TOMCAT]/conf/catalina/localhost/DataSourceExample.xml
Hope this helps,

Error: Class java.util.ArrayList not found in import

Bear with me, I'm learning. That's part of the problem.
I'm trying to teach myself JSP using a book based on Tomcat, but running it on an Oracle 9iAS server that I don't control. (The DBAs do that.) I'm running into constant problems compiling and using classes and such, I think because of the different directory structures on the two servers. (See subject error.)
So, what I'd like to know is: how do I set up a default/main/whatever-you-want-to-call-it directory under which I can store my practice applications, such that 9iAS will function correctly? We're not using OC4J as far as I can see (no such directory, though there is a J2EE_containers folder), just JServ. Or, conversely, can someone explain in simple terms the basic 9iAS directory structures for deploying apps on 9iAS? I've been 'round and 'round the Oracle documentation until my head spins, and can't find this basic information.
Help, please!!

You will have to make Kawa to use the correct jdk
Look into
Options-> Directory
Make a new Profile if it point to your old jdk version
Thanks

Converting ResultSet to java.util.ArrayList

Hi All,
Is there a way to convert the data contained in a ResultSet Object into an ArrayList, without iterating through the contents of the ResultSet using a while(rs.next())?
If so, please provide some snippets for the same.
Thanks,
Vikas

That answer (the edited part) was hopefully, not taken seriously. It's true, but mostly impractical (except the for loop, but why type the extra characters when it is no different from the while loop), and was, obviously (or, at least, hopefully, obviously) sarcastic.Some of us got it:D But yes, I think the clarification was a good idea!

Compiler error: incompatible types

When I try to compile this code it gives the error "incompatible types".
import java.util.ArrayList;
public class Poly {
     public static void main (String args[]) {
          Number integer = new Integer(1);
          ArrayList<Number> integers = new ArrayList<Integer>();
}Assigning a Number object an Integer which extends Number works fine.
But when I try to assign an ArrayList<Number> object an ArrayList<Integer> object it gives an imcompatible types error.
Shouldn't it work?

I've never seen ArrayList<? extends obj> before.Nitpick: it's not "? extends obj" it's "? extends SomeClass".
"obj" kind of implies that you could use a variable/field here, which is wrong.
I thought it would be able to hold an object which extends what it's supposed to hold.A List<? extends Number> could contain any class that extends Number (as well as Number itself if it weren't an abstract class). However you can't add anything (except null), because you don't know the concrete type at this point.

Incompatible types (Generics)

Can someone explain me please the following message I've got when trying to compile a file?
incompatible types
found : java.util.Iterator<E1>
required: java.util.Iterator<E1>
If the types are identical, how can they be incompatible???!!!
Thanks.

Hello,
I am stuck, I have a compilation probem. I am trying to compile my torque init class, and it gave an error message says that incompatible types. I am using Vector package to check the index of an element in the array. But the compiler found List instead of vector. Can you please tell me what's wrong.
