Java Class Gen gives "Expected EOF"

i'm trying to run the Java class generator using the command line utility, but keep getting an XMPParseException: Expected 'EOF'.
This happens with the dtd file included in the sample directory.
The class gen is 2.0.0.0 Beta, and it was bundled with the v2 parser. Any suggestions?

I got this error trying to generate classes based on schema definition file with namespace declaration. The catch here is to create a directory for each namespace declared and specify it before the schema file, i.e
oracg -p pakagename -s schemafile
if you switch the order of these arguments, you'll get EOF error.

'class' or 'interface' expected" on Connection class in java.sql.*

I am currently getting an exception "Main.java:20: 'class' or 'interface' expected". I had the database connection working, but then I tried to add something else and I feel like I might have changed something. I am wondering if there is a problem importing the java.sql. library; since that is where the Connection class is located. Thanks for your feedback.
package javaaaplication2;
import java.sql.*;
public class Main {
    /** Creates a new instance of Main */
    public Main() {
    public static void main(String[] args) {
        Connection con = getConnection();
        System.out.println("The connection is: " +con );
    private static Connection getConnection()
            Connection con = null;
            try
                Class.forName("com.mysql.jdbc.Driver");
                String url = "jdbc:mysql://localhost/patients";
                String user = "root";
                String pw = "qwerty";
                con = DriverManager.getConnection(url, user, pw);
            catch (ClassNotFoundException e)
                System.out.print(e.getMessage());
                System.exit(0);
            catch (SQLException e)
                System.out.print(e.getMessage());
                System.exit(0);
            return con;
    }

You closed your Main class with a bracket, so your getConnection() method isn't in a class
public class Main {
    /** Creates a new instance of Main */
    public Main() {
    public static void main(String[] args) {
        Connection con = getConnection();
        System.out.println("The connection is: " +con );
}That is your entire Main class. Anything below it isn't in the class.

Binding XML to java types generated using Oracle Class Gen

Hi,
how can you bind an XML to the java types generated using the class gen provided byOracle.
I am using oracle 9i production. as part of my design, i have to read an xml input in my java class and use the contents to create some records and send a response xml back.
The latter part of i can do as the java types provide setter methods to set the data and conversion to xml.
Jaxb can be using to bind xml to java datatypes but its not supported in Oracle9i.
What are the alternatives for achieving the same?
Thanks
Ashwin

Hi Ashwin,
This is a bit outside my area of expertise, but I did run an older version of TopLink in the Oracle database java VM a few years back so I'll base my advice on that. Hopefully other forum members can correct me if I steer you wrong.
First you will need to set up your XML environment:
I believe the Oracle 9i database includes a JDK 1.3 VM. You will first need to determine if the VM includes any JAXP APIs. I believe there is an SQL query that allows you to query the classes available in the VM. First check if javax.xml.parsers.DocumentBuilderFactory is present.
If the JAXP APIs are already present in the database you will need to do the following. First load the class javax.xml.namespace.QName into the database. You can extract this from xmlparserv2.jar or from Suns Java Web Service Developer Pack jax-qname.jar. Then you will need to load the JAXB APIs. You can load xml.jar or jaxb-api.jar from Sun's JWSDP.
If the JAXP APIs are not present you will need to load the 10.1.3 version of the XDK jars (these are shipped with the 10.1.3 TopLink install). Load xmlparserv2.jar and xml.jar into the database.
Second you will need to setup your TopLink environment:
Load toplink.jar into the database. If the JAXP APIs were already present and you didn't load the 10.1.3 XDK jars into the database you will need to set the following System property.
toplink.xml.platform=oracle.toplink.platform.xml.jaxp.JAXPPlatform-Blaise

Give all servlet capabilities to a normal java class

am new to servlets, i have one servlet class only, say index.java, in this servlet i have overridden its doGet/doPost where in those methods i just
create an instance of a normal java class say MyClass, am looking to make MyClass to have same capabilities like my index servlet, in other words
am wondering what parameters i need to pass to the MyClass constructor so that MyClass can do all what the index servlet does?
for the time been i am passing the HttpServletRequest and HttpServletResponse, but later i have a situation that i needed to know the path for a file
where i found that i should use ServletContext.getRealPath, so i found that extra ServletContext that should be passed to MyClass, so what exactly i need
to pass to MyClass so that it has all servlet functionalities?

You may want to review your application architecture.isnt the servlet thread-safe in its nature?

How can I compile and run other java classes from within an application?

Hello there everyone! I really hope that someone can help me. I am writing a program that must be able to compile and run other java classes that are in different files, much like development environments like Kawa or Forte allow you to do.
There has to be a way of doing this ( I hope!! ), but i can't seem to find it!!
I have tried using this command to compile:
Runtime.getRuntime().exec ("c:\\programs\\javac className.java");
...and this one to run:
Runtime.getRuntime().exec ("c:\\programs\\java className");
...but neither works!!! I can compile and run classes that are in the same file as my application, but I can't get it to work at all for files in different directories or files.
PLEASE, PLEASE, PLEASE help me - i've run out of ideas, and i need this to be working in 3 days!!!
Thank you very much for any help anyone can give me, I really appreciate it!! Thanks again!!
Adrian ( ...in distress!! )

public class JavaCompiler{

}This should get you going. You may consider looking into the System.getProperty() method in order to determine the type of OS it is running on in order to findo out what command to run. I know that the sun tool listed above is nice, but by my understanding the sun tools provided are not guaranteed to stay the same. I'm no expert on this matter, but that is one of the reasons there is no API documentation for those tools. Also, I don't believe those tools come packaged with the JRE. (Of course if you are making an IDE it will be expected that the user has an sdk installed. Good luck with figuring this thing out.

Synchronized method in a java class used by many interfaces

My interface (idoc to file) is using a java class, which has one method that reads a table from a central database and after doing some calculations updates it.
(The interface instantiate the class inside a user-defined function and calls the method there.)
The problem is that if somebody sends 100 idocs at the same time, there can be a dirty read, I mean, a read just before other interface updates the table.
We want the following:
Interface 1:
- Read counter from the table (counter = 5 )
- Increment counter (counter = 6)
- Update table with that counter (table with counter = 6)
Interface 2:
- Read counter from the table (counter = 6 )
- Increment counter (counter = 7)
- Update table with that counter (table with counter = 7)
RESULT: The table has the counter = 7
But what is happening is the following:
- Interface 1 reads (counter = 5)
- Interface 2 reads (counter = 5)
- Interface 1 increments counter (counter = 6)
- Interface 2 increments counter (counter = 6)
- Interface 1 updates table (table with counter = 6)
- Interface 2 updates table (table with counter = 6)
RESULT: The table has the counter = 6 (WRONG)
I made the method synchronized. What I was expecting was that only one interface (i1) could enter the method (read the table and update it) while other interfaces running at the same time would have to wait until i1 finished that method.
My first test indicates that's not happening. Can anybody help me to find a solution?

Hi Bhavesh,
If the QOS is EOIO this means that the integration engine manage the call to the mapping program (and all the other blocks) inside an "internal" synchronized method.
So this means that in this case you do not need to manage the queued access (synchronization) inside your custom java code because it is already enveloped in a queued block by XI.
The problem that Jorge had can be easily reproduced using the sample code that follows:
class Synch Object
import java.util.Date;
public class SynchObject {
 String strName;
 public SynchObject(String strName){
 this.strName = strName;
 public synchronized void syncWrite(String strCaller) throws InterruptedException{
 Date now;
 now = new Date();
 System.out.println("-- " + now.toLocaleString() + " " + strCaller + " entering syncWrite of " + strName);
 System.out.flush();
 Thread.sleep(1000);
 now = new Date();
 System.out.println("-- " + now.toLocaleString() + " syncWrite of " + strName + " called by " + strCaller );
 System.out.flush();
 Thread.sleep(1000);
 now = new Date();
 System.out.println("-- " + now.toLocaleString() + " " + strCaller + " leaving syncWrite of " + strName);
 System.out.println("");
 System.out.flush();
class Caller
public class Caller implements Runnable {
 String strName;
 SynchObject target;
 int intMax;
 public Caller(String strName, SynchObject target, int intMax) {
 this.strName = strName;
 this.target = target;
 this.intMax = intMax;
 public void run() {
 for(int i=0; i<intMax;i++)
 try {
 target.syncWrite(strName);
 } catch (InterruptedException e) {
 e.printStackTrace();
class Workbench
public class Workbench {
 public static void main(String[] args) {
 // TODO Auto-generated method stub
 SynchObject sObj1 = new SynchObject("syncObj1");
 SynchObject sObj2 = new SynchObject("syncObj2");
 Caller c1 = new Caller("caller1",sObj1,2);
 Caller c2 = new Caller("caller2",sObj1,2); '[*CHANGE*]
 Thread ct1 = new Thread(c1);
 Thread ct2 = new Thread(c2);
 ct1.start();
 ct2.start();
Run the workbench class to see what happen when setting QOS EOIO (the synch object is the same).
To see instead what happen now (missing synchronization) you have to change in Workbench class the statement
Caller c2 = new Caller("caller2",sObj1,2); '[*CHANGE*]
with
Caller c2 = new Caller("caller2",sObj2,2); '[*CHANGE*]
The reason is that every instance of the mapping program declare a new instance of the "Synchronized object" so the calls are synchronized inside the same mapping program but not between several mapping program.
Hope this give you a better idea on this problems with java synchronization, but if you have further doubts (I know it's a little bit tricky ) feel free to ask.
Kind Regards,
Sergio

Trying to invoke a Java class from BPEL Proces using Java Embedding

Hi All,
I have a requirement to invoke a Java class from the BPEL process;
I am trying to import the class by "* <bpelx:exec import="+package_name.classname+"/>*.

Hi,
I wud suggest you to make a jar of ur java class and include it in the project libraries of BPEL and make use of java embedded activity this way it works.

System.out from Java class not output to JSP

I am using JSP to make a Java API web accessible. I include (package) java classes that write error messages to standard out when they catch an error. Works fine on the command line. Problem occurs when using in JSP. I include them with a page directive (importing the package) rather than use them as beans, since they do so much more than beans do, and since I use many of the classes in a single page.
i.e.
<%@ page import="OPS.*" %>
When errors occur, messages to "standard out" (system.out) don't appear in the html output of the JSP. I don't know where they are going (they aren't in the web server's error log), but they aren't going where I expected them to (browser window).
I figured that standard out was the browser (httpServletResponse). Where am I going wrong here?
Basically, I have a class that connects to a database (call it db) and does queries/updates. I have a class (call it employee) that uses the db class. I have a jsp page that instantiates the employee class and executes method calls. The code in the db class that outputs SQL error messages (db class instantiated by employee class) never gets put in the browser window. Nor in the server log, nor the console.
How can I get system.out calls in classes db and employee to get output to the browser? The JSP outputs all other code and is not freezing nor not flushing the buffer.
Thanks!

I also use an Iplanet over which I have little control. But I can log on via telnet. If I log on (I use Reflection) and run my pages, the errors show in the Reflection window. If you have telnet access to the server, you might want to give this a try.
Another alternative would be to add a few lines to your classes that allow you to pass a reference to the jsp StringWriter from your jsp and use that to output the errors to the browser.

Compiling error......class or interface expected

and by the way sorry if this posted twice my computer is being a little annoying tonight

here ill put the whole thing of code......dont laugh if its crappy i just started learnign this shit

This program failed to compiled with the message "Class or interface expected" when declaring the JavaLearning1 constructor (line 17) and the private juggler1 variable (last line of code). It is not possible to see the code within initComponents methods in Netbeans Source Workspace. Is it possible that this is due to CLASSPATH not set correctly?
I am new to JavaBeans and would appreciate any guidances.
Many Thanks,
Netbeans Fan

Hi itchyscratchy,
Thanks for pointing the missing semi colon out but it was just a copy & paste error. The import statement does have the semi colon in it. Nevertheless, below is the output when compiling from Netbeans:

Error when generating java classes from object types

Hi,
I'm using JDeveloper version 10.1.3.0.2
I created an object type in the database, the definition is:
TYPE domain_cls IS OBJECT (
domain_idx NUMBER(3)
) NOT INSTANTIABLE NOT FINAL
I tried to create a java class for this object using JDeveloper, by using generate java menu item.
I got the following error:

I would recommend using JAXB instead of the Oracle class generator. This will give a standards based object-to-XML platform.
Oracle provides two JAXB implementations: one in the TopLink product, and the other in the XDK.
For an example of using TopLink JAXB see:
http://www.oracle.com/technology/products/ias/toplink/technical/tips/jaxb/index.htm
TopLink also provides the ability to map existing Java objects to an existing XML Schema, for an example of this see:

Having Problem With "static" When Running a Stand Alone Java Class

I have a Java class that recursively builds a 'tree' . This Java class works as I expected without problem. I am able to write out this 'tree" to the console "line by line" with proper indentation.
The problem occurs when I try to iterate through this 'tree' in the public static void main(String[] arg) method -- Each line in the tree is an Array. And I have to declare this Array (called titleArray in my code) non-static; otherwise, I end up with picking up the very last line of my hard-coded data.
Besides, I also have to declare the List (called recursiveTextArray in my code) non-static; otherwise, I end up with picking up the first Array that I ever build and run into endless iterations till the heap size is exhausted. Note that each element of that List is an Array object.
Then, this non-static Array and this non-static List cannot be accessed in the public static void main(String[] arg) method.
What should I do?
Here is my code that works without problem (the one I do not access the 'titleArray' in the main(String[] arg) method):
import java.util.Iterator;
