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.

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.

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.

It appears you are trying to store java objects (types) in a database rather than raw data (string, int, date types) that the object contains. If so, I don't think that ever really caught on. Most programmers store the raw data, then pull it out and populate a class. The problem with storing the object is that new versions of classes come out and your old version is stored in the database. If you just store the data, you don't have to worry about what version is in the database. You can populate the new version of the class with the same data.
Also, others can use sql to query your data and use it for their own use independent of what you intended it for. I think most people use the (browser) based utility that comes with the database to create the tables, normalize them, set up primary keys, set up foreign keys, etc rather then run an sql statement as you did above.

How can i convert data from DBF to oracle database 10g?

Sir,
How can i convert data from DBF to oracle database 10g?

I assume you at least know how to dump the contents of foxpro dbf file into CSV format.
Regarding SQL*Loader, hope this demo makes it a bit clear to you...
http://www.princeton.edu/~storacle/sqlloader_demo.shtml
I agree that it is an old web page (references Oracle 8.0.5) but basics remain the same.
If it is still unclear to you after referring above link, then get an Oracle consultant.
