Sun 8: ClassCastException from ManagementHome

I am trying to use JMX from Sun 8 using a java application client.
When I tried:
Context ctx = new InitialContext(properties);
Object objref = ctx.lookup("ejb/mgmt/MEJB");
ManagementHome home = (ManagementHome)
PortableRemoteObject.narrow(objref, ManagementHome.class);
I got error:
java.lang.ClassCastException
at com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java
:293)
at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:134)
What is missing from my program or environment?
My classpath is: .;d:\sun\appserver\lib\j2ee.jar;d:\sun\appserver\lib\appserv-rt.jar;d:\sun\appserver\lib\appserv-admin.jar
My java -version is:
java version "1.4.2_06"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_06-b03)
Java HotSpot(TM) Client VM (build 1.4.2_06-b03, mixed mode)
Any information would be appreciated. Thanks in advance.

Hi Hans,
Thanks for your advice: I set these three properties now. I can go one step futher.
Now I can get ManagementHome object without errors. But when I tried to call create(),
I got error below. What else do I miss?

ClassCastException from OraclePreparedStatement.setArrayInternal() method

The following code throws a ClassCastException from oracle.jdbc.driver.OraclePreparedStatement.setArrayInternal() method line# 5886 when cs.setArray() is executed.
Connection conn = getConnection(); // Returns a java.sql.Connection instance
CallableStatement cs = conn.prepareCall(queryString);
cs.setArray(1, new UsnArray(usns)); // UsnArray implements java.sql.Array
cs.registerOutParameter(2, Types.INTEGER);
cs.execute();
This works if I create the CallableStatement on an oracle.jdbc.driver.OracleConnection instance and use an oracle.sql.ARRAY instance in the setArray() method call. A JDBC-compliance driver shouldn't be expecting the applications to use driver-specific classes. The application can pass any instance of type java.sql.Array in the setArray() method call.
Is this a bug in the driver?

Let me elaborate on your last two replies: it doesn't matter what other drivers support; it doesn't matter what your "intention" was; all that matters is whether the implementation adheres to the specification or not. If it is not, it is not compliant to the specification (period). It is a very strong statement to say that "You must use oracle.sql.ARRAY." I'm not quite sure you understand the meaning and motivation behind standards like JDBC and J2EE and standards bodies like ANSI. This is very obvious when you say that "This is a limitation of the expressiveness of the Java type system."
If you think the JDBC compliance only mandates that "A driver is only required to accept a value that is of the concrete class defined by the driver," which is not mentioned anywhere in the spec anyway, then Sun would have simply defined the setArray method as "public void setArray(int i, oracle.sql.ARRAY x)" (one for each driver available) instead of saying "public void setArray(int i, java.sql.Array x)". It also clearly says that if a specification is not supported by a driver, in which case it must be specified in the DatabaseMetaData, the driver must throw a SQLEception. Bur your claim completely contradicts everything. You can also refer links like this on the Web: http://archives.postgresql.org/pgsql-jdbc/2003-07/msg00294.php.
I don't know what you mean by "The JDBC spec is not as precise as it could be." The relevant requirements have been clearly stated throughout Chapter 13 “Statements” and in Appendix B "Data Type Conversion Tables" in JDBC 3.0 spec (Chapter 8 Section 3 "Arrays" in JDBC 2.1 spec).
A JDBC driver may provide underlying data source-specific features in addition to those mandated by the JDBC specification. Applications that try to take advantage these additional features may decide to “stick” with a specific driver and import driver-specific classes. But these additional features cannot substitute the basic requirements.

How to run TCK using Java Card Sun reference model from eclipse

Hi all,
can any one help me by giving an idea about running java card TCK using sun reference model from eclipse IDE.
Thanks

tck should be able to run as stand-alone (with jcre).

ClassCastException from LDControl

Hi,
I am trying to invoke a LD Query using LDControl from a pageflow.
I keep getting java.lang.ClassCastException on method call to myControl.LDQueryMethod().
My guess is that its some data-type mismatch between the schema returned by the LD Query and the auto-generated XML Bean.
Is there any way to debug where this exception is coming from?

How to catch ClassCastException from JSP page?

I get a ClassCastException within my JSP page and I know where my bug is. However, this classcastexception message is displayed in the browser and I want to catch this exception to also log it into my log file. But I can't find the place where to catch it: in my servlet's doPost() method I can't catch it - i tried it by enclosing the method body with try/catch but it isn't catched. I wonder if I can catch it at all or if this error is handled internally in the servlet engine?

It should only be displayed in the browser if you're not catching the exception in the jsp itself. If the exception is happening in the jsp, then there's no point in trying to catch it in the servlet.
What happens if you put a try-catch just around the actual code in the jsp? You could put it around the entire jsp, but that's not necessary.
One problem I've encountered in catching exceptions is if there are escape sequences within the try block, for example:
try{
//java code
%>

<%
//java
catch (Exception e)I'm not sure if that works or not, but to be safe, make sure you're not escaping from jsp within the try block.

ClassCastException from appendSecondaryDocument( non-oracle-generated-XMLDocument i )

I wrote an xsql custom handler that converts html to xhtml and includes it into my xsql-generated xml.
It gets slow because appendSecondaryDocument() throws a ClassCastException if I pass in a (XML) Document that is generated by the parser in JTidy.
I therefore have to reparse this document using Oracle parser, which degrades performance too much.
Is there any way to avoid this reparsing?
I included code that shows the problem, the code relies on the JTidy library, which may be downloaded from:
http://sourceforge.net/projects/jtidy/

Looks like you already figure this one out, but basically the XSQL Page Processor expects the DOM implementation that is used to be the fast Oracle DOM implementation for performance reasons.

How does Sun make money from Java? Silly question.

Hi,
From what I have read about the J2SE licensing, we are able to download the SDK and develope commercial applications with it for free.
Have I made a big mistake in my reading? How does Sun make any money from Java?
Thanks very much.

Sun One deploy from 9.0.3

Is there a way to deploy from jdev to a sun one server using an admin jar and appserver connection? other than copying over the war/ear file, I mean ...

There is no built-in one click deployment to Sunone from 9.0.3
You might be able to use the external tools option to invoke some script that will take the needed files and deploy them.

Where to download Sun OpeESB components from?

Sun IDM 8.1 can be installed from scratch. No previous IDM versions are required. It is a full installation. Simply use MySQL as the repository database and Apache Tomcat as your application server.
Specific installation instructions for Sun IDM 8.1 on Tomcat can be found here: http://docs.sun.com/app/docs/doc/820-5594/ahtbq?l=en&a=view
Of course, first you need to prepare the DB and App Server: http://docs.sun.com/app/docs/doc/820-5594/ghrqf?l=en&a=view and http://docs.sun.com/app/docs/doc/820-5594/ghrsw?l=en&a=view, respectively.
Good luck.

Problems in Sun's Database from SCJD Exam

Hello,
Any does the SCJD exam between January - February 2008?
I did, but the Sun's database has a problem, so my exam went send by the inspector ONE MONTH later.

Hi Brian,
Thanks a lot. I don't have an oracle full java driver now. I'll try working with it. But the thing is, there is no error in syntax because i'm able to access the database now and then. But it doesn't work always. Moreover the one about the link! When I type a URL, it works fine but not with a location.href link or a flash link. To be frank with you I copied the working url and pasted it into the link, but still that doesn't work. What is the reason for all this? Even despite including "con.close()" statement in my page, why does the connection still continue? When is the connection actually established? Supposed to be when I submit the form!! Please reply at your earliest.
Thanks a lot once again...

Argh; it's a bug. It'll only happen when the data cache is enabled, by
the way. Darn... you'll have to make due with casting to
kodo.query.KodoQuery.
Was there a specific JDBCQuery method you needed to invoke?Yes... setJoinSyntax().
