Problems with protected access in java.util.vector
Hi,
basically i'm trying to use the method removeRange(int,int) of class Vector from the java API.
I keep getting the following compiler message:
removeRange(int,int) has protected access in java.util.vector.
This seems rather vague, and i don't know quite what to do?
Thanks in advance
removeRange(int,int) has protected access in java.util.vector.
This seems rather vague, and i don't know quite what to do?As error messages go, that's pretty clear: method removeRange is a protected method and you can only call public ones of Vector, right? You can always combine subList and clear:
vec.subList(fromIndex, toIndex).claer();

I'm studying for the JCP exam. I've come across a question:
True or false: If class Y extends class X, the two classes are in different packages, and class X has a protected method called abby(), then any instance of Y may call the abby() method of any other instance of Y.
A. True
B. False
And the answer:
B. An object that inherits a protected method from a superclass in a different package may call that method on itself but not on other instances of the same class.
However, I wrote such piece of code:
File Foo.java in foo package:
package foo;
public class Foo {
protected void fun() {};
}File Main.java in package test:
package test;
import foo.Foo;
class Main extends Foo {
void test() {
fun(); //this is supposed to work
Main m = new Main();
m.fun(); //but this is not - but it works!
public static void main(String args[]) {}
}So, could anybody explain this to me? Is there a bug in the book I am using or is it me who doesn't understand everything?
The book: Sybex, Complete Java� 2 Certification: Study Guide, Fifth EditionThat Sybex book is full of errors. This is only one of them. For example, it tells me that the classpath I specify with -cp MERGES with the system classpath -- anyone who has basic experience with it knows that this is crap.
Also, there are not just errors, but omissions. For example, it leaves out the whole section about the shift operators (<<, >>, >>>), but there are questions in the book about them. It explains <? extends A>, but not <? super A>.
Or it tells that you can use the class lock in the body of static methods, but does not explains how! The simplest I could come up with is synchronized(Class.forName("myPackage.myClass")); yes, in a try-catch construct.
The exam questions are also strange. For example, there is a question about void callMe(String? names). According to the book, the correct answer is "names is an array of Strings in the method". That COULD be true, if it compiled. But it does not...
I would suggest to learn from another book. Unfortunately I don't know if there are other books for Java 5 yet. -
ClassCastException: java.util.Vector
I'm trying to get a list of records(products) from the dataBase and print them into a jsp page.
Here is the code-
Method in session bean to get the records-
public List<Entity.Products> getProducts(int categoryId)
Query query=manager.createNativeQuery("select * from products where categoryId="+categoryId);
return (List<Entity.Products>)query.getResultList();
}I put the result in the request (in a servlet)-
request.setAttribute("products",productsManagement.getProducts(categoryId));JSP page-
<%
java.util.List<Entity.Products> products=(java.util.List<Entity.Products>) request.getAttribute("products");
for(Entity.Products product : products)
%>
<A href=""><%=product.getProductName()%></A>
<%
%>The problen is that i'm getting the error-
java.lang.ClassCastException: java.util.Vector
what is the problem?
Thanks in advanced.ppl1,
Your problem is with createNativeQuery. Native query returns a Vector of objects. Whereas createNamedQuery (based on JPQL) is smart enough to get the types right. It seems like you want to use createNamedQuery which will allow you to use generics with the Entity type.
For example, with a client
List<Products> products = prodMgr.findAllProducts();
for(Product p : products) {
System.out.println(p");
}The following session bean will work.
// ProdManager
@PersistenceContext EntityManager em;
public List<Product> findAllProducts() {
// JPQL for findAllDepts: SELECT p FROM Product AS p
return em.createNamedQuery("findAllDepts");
}If you are committed to native query, use the following on the client and EJB respectively.
List products = prodMgr.findAllProducts();
for( Object obj : products ) {
System.out.println( obj.toString());
// use a case "(Product)obj" for field-level access
List findAllProducts() {
return em.createNativeQuery("SELECT * FROM products").getResultList();

Problem with file access in other computer in jsp
I have problem with file accessing in other computer in jsp.
The follow code
File folder=new File("Z:"+File.separator+"sharefolder");//Z is a net share driver
File[] files=folder.listFiles();
System.out.println("test");
System.out.println("length="+files.length);
will throw exception at the second print.
but it works well in main funtion.
Is anybody know what is the problem.

Hi All,
I try to run an applet from Solaris 8 server on some client machine using IE5 and NetScape 6.2 ( I installed JRE 1.4, I also try other JRE versions) but I get the following errors again and agian,
I even try to use appletviewer on the Solaris Box itself to open the applet but it makes no difference same errors
could somebody please help or give me a hint how should I start tracing what the problem might be ?
this applet comes with Solaris Bandwidth Manager as a gui administration tool ( webbased ) it supposed to change the configurations remotly over the web. I asure there is no solaris permission problem exist.
I use Tomcat on the server side.Installed JDK 1.3 on Solaris 8 with all the default settings.
i suppose something should be done with java.policy or java.security files i know nothing about java security please at least give me some URL's to find out more about this matter i searched a lot but couldn't find good documents about java default security restrictions

mehmadI dont know, but It may be that an Applet can only access the local machine. ie. If you run the applet on computer A and you want to edit the config on computer B, I do not believe you can. The applet can only talk to Computer A. You would have to:
1) Run an application on computer A and the applet would tell the application what to change.
2)Maybe sign the applet in a JAR File
You will probably have to do #1.

mehmadHi,
Please make changes in the java.security files present in the jdk1.3/lib/jre/security/java.security.There you make the changes in the property which gives you the error.See if this helps..
regards vickyk -
This looks like it might be a bug in 6.1SP5,
weblogic/kernel/Kernel.java at line 85.
It's trying to do the right thing to ignore an exception if in
an applet but it's ignoring the wrong exception
(SecurityException, when it looks like the stack
trace is throwing a java.security.AccessControlException).
If you need a fix, this would need to go through support
and be filed as a problem with WLS Core.

I suggest going through customer support, I don't know what
the resolution was. You might also try the security newsgroup,
as no JMS code has been called by the application yet at
the point the exception is thrown.

After using jexegen from microsoft to make EXE. I receive this error when i execute the my EXE :
java.lang.NoSuchMethodError: java/util/Vector method revove...
Any body know why?
If i execute from JBuilder i have no problem!hi, i don't have much experience with M$ java products, but as far as i remember, M$ java stopped developping since jdk 1.1.4 (or 1.1.7).
maybe that's the reason for throwing this exception. if you want to "exe" your class-file, try JToExe.

thanxs in adavance
DeepakHi I think you are using the method elements() in a remote method.
This method can't be Serializable!! Because it returns an Interface. Interfaces are never Serializable.

Thanks,
RamPrasad,
It's one thing not to have to modify the security policy on the server,
but on a client and applets have even bigger restrictions this might
very well be the only way since the default applet restrictions would
not allow a lot of permissions granted by default for normal Java
applications.

Ram,
You are missing a permission grant in your policy file and the
SecurityManager doesn't allow the code to read that property.
You have either configured a different security manager or have the
wrong file in use.
For applets this file might be in the user's home directory and named
.java.policy
you need to have the following line somethere in it:
grant {
permission java.util.PropertyPermission "*", "read,write";
Which will allow any applet to read and write any JVM property.
Look at Java permissions is you need more info:

This is a WLS bug. You shouldn't have to modify security policy.
Please approach support for a fix.

I don't know what is happening. JMS hasn't been called yet -
the applet is still setting up its initial context. You might want
to try posting to the jndi (and perhaps rmi) newsgroup.

Hi everybody:
I created a Mobile service component and a Data Structure with 3 attributes. I created and instantiated the collection and showed all objects in a table but I´m getting the following error:java.lang.NoSuchMethodException: java.util.Vector.isX() where X is the name of the each attribute I defined. so I´m getting this error twice for each attribute.
Complete stack:
java.lang.NoSuchMethodException: java.util.Vector.isX()

The errors are throw when the application starts, the custom code works ok.
Any idea?
Thanks a lot for your time on this thread.

Java.io.NotSerializableException: java.util.Vector$1
I am using Java 2 in the API it says that the Vector implements Serializable but I am getting an exception java.io.NotSerializableException: java.util.Vector$1 I don't know why please help.
Thank you
palanisrAlthough Vectors are Serializable that doesn't mean that the contents of a Vector are necessarily Serializable. What are the contents of your Vector? Are they objects of a Serializable class? If not that is your problem. The attached sample code demonstrates the problem of serializing a Vector that contains non-serializable data. If you make the Employee class Serializable the code works.
import java.util.*;
import java.io.*;
public class Serialize
public static void main(String args[])
ObjectOutputStream oos = null;
FileOutputStream fos = null;
Vector v = new Vector();
v.add(new Employee("Smith","John"));
v.add(new Employee("Jones","Albert"));
try
fos = new FileOutputStream("vector.ser");
oos = new ObjectOutputStream(fos);
oos.writeObject(v);
catch(FileNotFoundException fnfe)
fnfe.printStackTrace();
catch(IOException ioe)
ioe.printStackTrace();
finally
try
if (oos != null)
oos.close();
catch(IOException ioe)
try
if (fos != null)
fos.close();
catch(IOException ioe)
class Employee //implements Serializable
private String lastName;
private String firstName;
public Employee(String lastName, String firstName)
this.lastName = lastName;
this.firstName = firstName;

probably a ClassCastException. Why don't you get the stack trace?
