Support of Query newQuery(java.lang.Object compiled)

The implementation of the Query newQuery(java.lang.Object compiled)
method doesn't copy the Class of the candidate instances but it should
ad the documentation says :
"All of the settings of the other Query are copied to this Query, except
for the candidate Collection or Extent."
Thanks.

You can't query on a blob column.

Double click the project to go to project settings, then go to libraries and add a library with the jar files you added.

Error: invalid file 'java/lang/Object.class' (wrong version: 48, expected 4

hi all
ive installed jdk1.4.1 from jdk1.3 .
When i try to compile a java file i get this error.
Error: invalid file 'java/lang/Object.class' (wrong version: 48, expected 45)
anyone has any idea abt this.
im stuck :( pls help.
thanks
Jan

Did you uninstall 1.3 completely? Completely in the sense both jdk and jre.
You may get this error if you use javac of one version and the rt.jar of another version.

JBuilder: Failed to Load Super Class java.lang.Object

Hi I am a beginner of JBuilder. When I tried to compile some samples from JBuilder, the compiling failed because "Failed to Load Super Class java.lang.Object." Any clue to fix the bug?
Mark

Hi
Thanks for you guys' help. I found that when I create a project, the JBuilder's JDK homepath pointed by default to a JDK directory not existed. Therefore, I modified the JDK homepath through Tools/Configure JDKs. Then it worked.

Help! How to convert an instance from java.lang.Object to a particula class

* How to convert an instance from java.lang.Object class to a particular class
witch is known only at the running time?
Roster EJB component is make up of RosterHome, Roster and RosterBean.
RosterHome is the home interface of Roster EJB.
Roster is the remote interface of Roster EJB.
RosterBean is the implement of Roster EJB.
The following code segment is to invoke Roster EJB component.
String jndiName="roster.RosterHome";
javax.naming.Context initial = getInitialContext();//getInitialContext() returns a instance of Context.
Object objref = initial.lookup(jndiName);
RosterHome home =
(RosterHome)javax.rmi.PortableRemoteObject.narrow(objref,
RosterHome.class);
Roster myRoster = home.create();
String team="T1"
String player="Tom"
myRoster.addPlayer(player,team);
But, now, all the home interface, the remote interface and the JNDI Name of
Roster EJB component are not been known at the compiling time. However They are
known at the running time, throught reading from the XML config file.
Questions:
1,How to write code for this case ? or
2,How to convert an instance from Object class to a particular class witch is known
only at the running time?
String jndiName="roster.RosterHome";// in fact, reads from XML file.
String homeClassName="roster.RosterHome";// in fact, reads from XML file.
String remoteClassName="roster.Roster";// in fact, reads from XML file.
javax.naming.Context initial = getInitialContext();//getInitialContext() returns a instance of Context.
Object objref = initial.lookup(jndiName);
Object objHome= javax.rmi.PortableRemoteObject.narrow(objref,
Class.forName(homeClassName));
/* how to do next?
}

I am not sure what you are trying to do. But at some point you should know which methods to call on the remote interfaces. Maybe the method names are stored in the XML file as well or you have a set of standard method names (also consider parameters).
However, this can be solved by reflection. Look at the java.lang.reflect package, especially java.lang.reflect.Method, and also at java.lang.Class.
If you are doing this on the app server:
I've seen posts where people say that reflection is not permitted in EJB, but I don't think so. Check the EJB spec.
If you are doing this in an application: reflection is always permitted. Probably also in applets and JSP.

JDOQL queryfilter failure while retrieving field of "java.lang.Object" Type.

PROBLEM DESCRIPTION --->
JDOQL FILTER ON A FIELD OF "java.lang.Object" TYPE, NOT WORKING.
HELP REQUESTED WITH SUGGESTIONS OR POINTERS TO THE CORRECT SOLUTION.
Deatiled Problem :=
Environment :=
Kodo version 2.4.1 (on Windows 2000).
J2SDK 1.3.1_06 (on Windows 2000).
Database:= MySQL 3.23.55 (on Windows 2000).
Java Class Hierarchy Example:=
SuperPersistentObject
|__ LevelOneDescendant
|__ LevelTwoDescendant
|__ LastDescendant
Procedures Followed :=
Java class named "LastDescendant" is enhanced and persisted in the
database.
The field "m_value" is of java type "java.lang.Object" and is
represented as a "blob" in the database.
Aadequate data is pumped in the field "m_value" (Data of Type
String/Integer/Double/Boolean etc.). The class "LastDescendant" is
retrieved using following JDO specific code :=
SUCCESSFUL EXAMPLE :=
Extent extent= PersistentManager.getExtent
(com.name.project.LastDescendant.class, false);
String m_queryFilter = "";
Query query = PersistentManager.getQuery(extent, m_queryFilter);
Collection m_resultset = (Collection)query.execute();
The above code returns all the available "LastDescendant" objects
persisted in the DB. Post Load, The value in the field "m_value" of
all the retrieved "LastDescendant" objects, is testeded successfully
and found to be matching to the expected values.
FAILED EXAMPLE :=
Extent extent= PersistentManager.getExtent
(com.name.project.LastDescendant.class, false);
//Retrieving only the objects whose "m_value" field contains Integer
// values, between 10 and 9000. (110 objects with Integer value
// between 10 and 9000 are pumped in the DB, for testing).
String m_queryFilter = "(m_value >= 10 && m_value <= 9000)";
Query query = PersistentManager.getQuery(extent, m_queryFilter);
Collection m_resultset = (Collection)query.execute();
NO "LastDescendant" OBJECTS RETRIEVED, the Collection "m_resultset" is
Empty, (Actually Expecting 110 objects).
Tried every other way, using "declareImports()"/ "declareParameters()"/
"declareVariables()" etc. Tried TypeCasting the m_value field to Integer,
but to no avail.
Actual Classes :=
public class SuperPersistentObject implements java.io.Serializable {
protected String appKey;
public class LevelOneDescendant extends SuperPersistentObject {
protected SuperPersistentObject m_classRef;
public class LevelTwoDescendant extends LevelOneDescendant {
protected Object m_value;

Cannot find java.lang.Object

hi, all. i tried compiling my class using KToolbar but it cannot load some of my classes on the other package. so i tried compiling it using the command line. I am encountering a problem and the error message is that it cannot find the java.lang.Object. I already included tools. jar in my classpath but it didn't work. Do you know guys, what I am missing?
Thanks,

NoClassDefFound java/lang/Object error

Hi all,
I just tried to install JRE 1.4.1 on Win98 and encountered this error when I typed in java -version:
error occurred during initialization of VM
java/lang/NoClassDefFoundError: java/lang/Object
After I installed I added SET CLASSPATH = and the path to my rt.jar and tools.jar to my autoexec.bat, but that didn't seem to work.
Sorry about posting this here if it isn't appropriate, I tried a forum search but kept getting Server Error.

Look at this thread:
http://forum.java.sun.com/thread.jsp?forum=54&thread=106425
Think it is reply 3 or 4, where you have to rename the the java.exe file somewhere in your system path

Sort(java.util.LinkedList java.lang.Object ) doesn't work

Why doesn't this work?
LinkedList<Object> sysPropsKeys = new LinkedList<Object>(System.getProperties().keySet());
Collections.sort(sysPropsKeys);
cannot fnd symbol
symbol : method sort(java.util.LinkedList<java.lang.Object>)
location: class java.util.Collections

I will admit to not having Java1.5 installed on my machine. Haven't yet had the chance to play with generics, but the above DOES work in 1.4, and SHOULD work in 1.5
Maybe I'm naive but, System.getProperties() returns a Properties object right?
According to the API: http://java.sun.com/j2se/1.5.0/docs/api/java/util/Properties.html: Each key and its corresponding value in the property list is a string.
All the keys SHOULD be strings.
AFAIK string are comparable, and shouldn't throw class cast exceptions
Thus the keys returned from getProperties SHOULD be comparable, and compatible for comparision.
Ok, I can see your point in that some hackers abuse the Properties class by putting non string keys/values into the Properties Map. In that case the code would become more like your above. I'd probably still go with a TreeMap though, rather than a sorted list of keys. Most time you want the keys, you want the values as well. So if the intention is to print out a sorted list of system properties, and their values, keeping it in a map is best.
Just my 2 cents,

Javah error java.lang.Object not found

Hi guys-
I'm trying to run a javah command to generate a .h file... I'm using windows2000 & jdk1.1.8... when I run the command from DOS prompt I keep getting the same eror as java.lang.Object not found: aborting.. I've checked all the classpath and it seems ok ... I have CLASSPATH=..;c:\jdk1.1.8\lib\classes.zip
Can anybody help me with this???
Thanx

Maybe try ; right click my computer ,click the advanced tab and select enviroment variables,click on classpath and then edit,check if it's correct.I had the sam problem and that seemed to fix it. :)

Weblogic - a web service with java.lang.Object parameter

hi all,
i'm creating a web service with a java.lang.Object parameter.
my question is as follows:
when a client calls the web service, how to i get the soap message object and convert it to soap message string using the parameter?
thanks,
alex

Here's some code from one of the Axis samples, this shows the basic process of making a call:
package samples.message;
import org.apache.axis.client.Service;
import org.apache.axis.client.Call;
import org.apache.axis.message.SOAPBodyElement;
import org.apache.axis.utils.Options;
import org.apache.axis.utils.XMLUtils;
import org.w3c.dom.Element;
import java.net.URL;
import java.util.Vector;
public class TestMsg {
public String doit(String[] args) throws Exception {
Options opts = new Options(args);
opts.setDefaultURL("http://localhost:8080/axis/services/MessageService");
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress( new URL(opts.getURL()) );
SOAPBodyElement[] input = new SOAPBodyElement[2];
input[0] = new SOAPBodyElement(XMLUtils.StringToElement("urn:foo",
"e1", "Hello"));
input[1] = new SOAPBodyElement(XMLUtils.StringToElement("urn:foo",
"e1", "World"));
Vector elems = (Vector) call.invoke( input );
SOAPBodyElement elem = null ;
Element e = null ;
elem = (SOAPBodyElement) elems.get(0);
e = elem.getAsDOM();
String str = "Res elem[0]=" + XMLUtils.ElementToString(e);
elem = (SOAPBodyElement) elems.get(1);
e = elem.getAsDOM();
str = str + "Res elem[1]=" + XMLUtils.ElementToString(e);
return( str );
public static void main(String[] args) throws Exception {
String res = (new TestMsg()).doit(args);
System.out.println(res);
