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. -

Can't convert int to java.lang.Integer.
Hi everyone.
I'm working on an auction site at the moment and have problems gaining a bidID number. This is part of my code and my error.
AuctionFacade aHse = (AuctionFacade) application.getAttribute("AuctionFacade");
String strTraderName = (String)session.getAttribute("traderName");
String strPassword = (String)session.getAttribute("password");
String strIDNum = request.getParameter("auctionID");
Integer intID = Integer.valueOf(strIDNum);
Integer [] bids = aHse.getAllBids(intID);
float fltYourBid = aHse.getBidPrice(bids.length);
^
Can't convert int to java.lang.Integer.
can anyone help please?So, does "aHse.getBidPrice" expect an int or an Integer as its parameter? And does it return an int, or an Integer, or what? The answer to those questions may lead to your solution -- look at what you are actually using as the parameter, for example.

How to Convert From HEX to Java Unicode
String hexString = "81698a94816a93fa97a790bb8dec8f8a814083478393835e815b83768389834383598354815b836f8e968bc69594814083568358836583808c9f8fd8835a8393835e";
I have an hex string as shown above. Could please some one tell me how to convert to java unicode.Divide it into four-character pieces and for each piece to this:char c = (char)Integer.parseInt(thePiece, 16);That converts the four-character piece (e.g. "8a94") to the corresponding Unicode character (\u8a94). String those chars together into a char array or a String or whatever you need.

Mediator To Spring Error-Could not convert from java interface to interface
Hi,
I have a requirement to using a Spring component and my composite application would be File Read -> Mediator -> Spring Component -> File Write.
I have to read a file and using mediator map the same to the Spring input and write the Spring component output to a file.
I have created a Java interface ( Package Name - transformtospring , Interface Name - TransformInterface) and also created a Java Class ( TransformImpl ) which implements the Interface in this package. Saved all these artifacts in SCA-INF/src folder of the application.
My Spring Bean configuration file is as follows ( saved the file in the same folder as composite.xml )
<?xml version="1.0" encoding="windows-1252" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:util="http://www.springframework.org/schema/util"

<!--Spring Bean definitions go here-->
<bean class="transformtospring.TransformImpl" name="TransformBean"/>
<sca:service name="TransformService" target="TransformBean"
type="transformtospring.TransformImpl"/>
</beans>
I have created a Spring Context which uses the above Spring Configuration. When i tried to map the mediator output to Spring , i'm getting an error shown below.
" Could not convert from java interface to interface type wsdl . Exception=java.lang.ClassNotFoundException transformtospring.TransformImpl "
Please do let me know where exactly i'm doing wrong.
Regards,
Sri.Hi All,
I could able to work this one out now !!!
But i'm having an issue mapping the input to this service. The method signature for the service is as follows:
public byte[] processData(byte[] input) throws Throwable{
So the input for this Service is a byte array. Now i'm mapping the data from a File Input ( Read File - opaqueElement ) to this service directly ( using mediator ).
Now when i have looked into the message in the Enterprise Manager, following is the message structure from Read File input to the service.
<message>

I have included System.out statements in my Java class , but its not printing anything in the logs.
I'm under the impression that the underlying infrastructure ( mediator ) transparently encodes and decodes data from base64Binary to java byte array. So could anyone help me on this !!!

Could not convert from java interface to interface type wsdl ??
i have a problem wheni have a problem when i develop bpel using mediator and wire to ejb service. When the mediator wire to ejb service, i found the error : Could not convert from java interface to interface type wsdl.... How to solve the problem?
I followed the case closely (with the same name of classes, methods, etc), but still get the error: “Could not convert from java interface to interface type wsdl.Exception=nl.amis.calculator.Calculator”. I created a Java class to test the lookup and function correctly. However, when I try to wire a Mediator to this Reference, I run into an Interface Conversion Error. I’ve included the line javaInterface = “nl.amis.calculator.Calculator” in file composite.xml, but still get error. Could you help me?

Integer and java.lang.Integer?
hi
I'm using DefaultTableModel method getValueAt which takes 2 integers as parameters
i have the vector colnumbers which has integers in it. Im trying to get these integers back out again to use in the getValue at method but the compilercomplains that i need int,int nad not int, java.lang.Integer.
Why are there 2 different integers? and how do i just get it back as int????
thanks
Vector unsorted = new Vector();
for(int j=0; j<colnumbers.size(); j++)
for(int i=0; i<=max_rows; i++)
unsorted.add(tm.getValueAt(i,(Integer)colnumbers.elementAt(j)));
}unsorted.add(
tm.getValueAt(
i,
((Integer) colnumbers.elementAt( j )).intValue()
);you just needed to parenthesize to indicate that intValue() gets called on the result of casting colnumbers.elementAt( j ) to type Integer. -
Java.lang.Integer defaulting to zero
I am using JAXB for several years, but never dived into details.
I am not using a schema.
When I am unmarshalling a XML file, JAXB always defaults my java.lang.Integer attributes to zero instead to null, when the attribute is not given in the XML file.
How can I change this? I like the Integers to be null, just like in a "normal" Java program.
Thanks

It assigns null when attribute is not given in XML, this is similar to your need.
Which version of JAXB are you using? -
Required: java.lang.Integer
This is test.java:
import java.lang.Integer;
class Testit {
Integer ix = (Integer)1;
This is the result of the javac:
javac ca\test.java
ca\test.java:4: inconvertible types
found : int
required: java.lang.Integer
Integer ix = (Integer)1;
^
1 error
Can anyone explain this?
Java is mysterious.
Thanks,
Grant HeadThis is because 1 is not object in Java. Any integer is primitive type. They are not object. So you cannot cast them into object. If you want to creat Integer object from integer. Simply do following...
import java.lang.Integer;
class Testit {
Integer ix = new Integer(1);
}However, in C#, everything is object. Any integer, floating points are all object. That's one of difference between Java and C#.
Hope this help. :)

try {
for(int tByte; (tByte = ivIn.read()) != -1; ) {
ivOut.write(tByte);
ivOut.flush();
catch(IOException e) {
e.printStackTrace();
// Start process
Process tProcess = Runtime.getRuntime().exec(pArguments);
// Create out printer
Thread tOutPrinter = new Thread(new ProcessOutputPrinter(tProcess.getInputStream(), pOut), "NamingAdmin out-printer");
tOutPrinter.start();
// Create err printer
Thread tErrPrinter = new Thread(new ProcessOutputPrinter(tProcess.getErrorStream(), pErr), "NamingAdmin err-printer");
tErrPrinter.start();

Dyna Form +Validator Framework--- peculair problem with java.lang.Integer

Now if user does not enter name , then a error meassage is dispalyed,
and aslo this time phoneNo shows 0.
why 0 is displayed here?
Can anybody tell meHi all,
If my memory serves me well, the exception is thrown because the application needs a working calendar for a person provided in time mangement. Make sure the correct infotypes are used. Also the organization structure needs to be set up correctly. The manager needs someone to approve and the employee needs someone to get approved by.

Cannot convert from java.util.Date to java.sql.Date
In the below code am trying to get the current date and 60 days prior date:

Date Sixtydaysprior;
String DATE_FORMAT = "MM/dd/yy";
DateFormat sdf = new SimpleDateFormat(DATE_FORMAT);
Calendar cal = Calendar.getInstance();
todayDate = sdf.parse(sdf.format(cal.getTime()));
cal.add(Calendar.DATE, -60);

I don't think this exception is thrown from the portion of code you have shown. As clearly specified in exception message, you cannot cast an instance of java.util.Date to java.sql.Date. you will need to do something like this
java.util.Date today = new java.util.Date();
long t = today.getTime();
java.sql.Date dt = new java.sql.Date(t);
