hi all....
please help me to program java card stuff for my project...
I am want to use the java as as authentication module to identify the some sort of signature.
please let me know the codes or steps do i have to follows....
i am using jcop2.2 .....
do i have to learn the javacard shell programming too..? i am good in java but not this technology...
i have tried the sample example in java_card_kit-2_2_1 but i could not do anything...:(
please help me

lanaka

It's like u r asking someone to do ur homework.
1. sample example you have mentioned can't work on JCOP
2. yep, you'll have to learn how to work with JCShell if u want to use jcop tools.
3. Read HELP that is provided with 2.2 tools. It's from big help for beginners.
(there is even one signature example in it)

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.

How to Create adf table from java bean

Hi,
How to Create adf table from java class (Not from ADF BC).
Thanks
Satya

@vlsn -- you have to follow what shay said.
Do the following in Model layer ::
create a table property java class with your columns setters and getters like :
*public class gridProps {*
private int sno;
private String orderNum;
*public void setSno(int sno) {*
this.sno = sno;
*public int getSno() {*
return sno;
*public void setOrderNum(String orderNum) {*
this.orderNum = orderNum;
*public String getOrderNum() {*
return orderNum;
Create another table java class which will populate the values to your column values and return the collection :
*public class gridPopulate {*
private List<gridProps> gridValues ;
*public List<gridProps> setToGrid(ArrayList<ArrayList> valuesToSet) {*
*if (valuesToSet == null) {*
return gridValues;
gridValues = new ArrayList<gridProps>();
if(btnValue.equals("completeBtn"))
return gridValues;
for(ArrayList<String> tempArr:valuesToSet)
gridProps gp = new gridProps();
gp.setSno(Integer.valueOf(tempArr.get(0)));
gp.setOrderNum(tempArr.get(1));
return gridValues;
Right click gridPopulate class and create this as data control.This class will be seen in Data control list.Under this data control,Drag the grid property collection(created earlier) to your page.Then execute your binding(gridPopulate) according to your logic.
Thanks.(My jdev version 11.1.1.5.0)

How to execute Linux command from Java app.

Hi all,
Could anyone show me how to execute Linux command from Java app. For example, I have the need to execute the "ls" command from my Java app (which is running on the Linux machine), how should I write the codes?
Thanks a lot,

You can use "built-in" shell commands, you just need to invoke the shell and tell it to run the command. See the -c switch in the man page for your shell. But, "ls" isn't built-in anyays.
If you use exec, you will want to set the directory with the dir argument to exec, or add it to the command or cmdarray. See the API for the variants of java.lang.Runtime.exec(). (If you're invoking it repeatedly, you can most likely modify a cmdarray more efficiently than having exec() decompose your command).
You will also definitely want to save the returned Process and read the output from it (possibly stderr too and get an exit status). See API for java.lang.Process. Here's an example
java.io.BufferedReader br =
new java.io.BufferedReader(new java.io.InputStreamReader(
Runtime.getRuntime().exec ("/sbin/ifconfig ppp0").
getInputStream()));
while ((s = br.readLine()) != null) {...

How to call gnuplot command from java

Hi there,
In our course, we are required to develop an GUI for gnuplot. In case you don't know about gnuplot, it's a plotting program and has lots of command. We want to use java and swing, but now we don't know how to call gnuplot command from java, or how to execute a shell command(script) from java.
By the way, since we need read in files with several columns of data and allow user to select a column, we want to use JTable. Is that reasonable?
Thanks a lot for any suggestions!
Jack

Hi, there:
Will using JTable add much overhead? I may have to use several JTables and switch among them. I can add scroll bar to or edit JTables, right?
BTW, do you have experience about gnuplot? Can I find the command tree of gnuplot somewhere? Or do you know a better place to post question about gnuplot? unix/linux group, maybe.
Thanks,
Jack
P.S. Would you guys answer my question after I use up my duke dollars? :- )

I need to know how to set environment variables from java
I want to set from java for example the environment variable "TestVar" with the value "TestValue"!1) That functionality does not belong in an application. You're trying to set environment variables, which are global across all applications, at either the user level as a whole, or across the entire machine (system level). Or, if you're only trying to set a variable active for the current process, you don't need to do that.
2) Environment variables are not a platform-independent entity, and are thus against the nature of Java.
My gut feel is that you are designing something in a backwards way, so my point is mainly to point that out, not to try to help you solve that particular problem.

Creating java code from a class diagram in JDeveloper

I have created a class diagram in JDeveloper 11.1.1.3.0. When I generated java code from the class diagram by right clicking on the class diagram->transform->same diagram->UML to Java, a .java file is generated with attributes and getters/setters, and also a .uml_cla file is generated. What is this .uml_cla file exactly and what is it used for? Also I have a package.uml_pck file that was created 3 times. I have a package of com.xxx.xxxx, and it put this package.uml_pck file in "com", in "xxx", and in "xxxx". Do I need to retain all 3 of these files in my project?
One more question related to this. When I change something in the java representation of the class diagram (i.e. a datatype), it updates the .java file that was generated from the class diagram, and it also works the other way...change the .java file and the java representation of the class diagram changes. However, the class diagram that the code was generated from does not change, nor does the mysterious .uml_cla file I asked about in the above paragraph.

This did work for me, with an exception. I have put the .java files generated from the class diagram in a different package from the .class_diagram file, the package.uml_pck file, and the .uml_cla file to keep the actual source code separate. When I modified the .java file and transformed the class diagram from java to UML, it created the package.uml_pck file and the .uml_cla files again in the same package as the .java file, and they show the update. The package.uml_pck file, and the .uml_cla file that were originally created and are in the separate package from the .java files were untouched, thus the class diagram displayed does not reflect the change either. Does this mean I should not, or cannot, separate these files, and that they all must be left in the same package? (the purpose of separating it in the first place was for ease of deployment since we don't want to deploy any of the class diagram files) Thanks!

Starting exetutable java file from java code

Hi I was wondering how I can start a executable java file from java code?
thanks

Hi Mkaveli,
Yes, it's possible. If you have a JAR executable, you've just to call the main method of its starter class. For a simple executable class, just call its main method.
This way :
SomeStarter.main(null); // if there's no argumentSmall precision : the executable JAR or class must be specified in the classpath of your application.
