How to insert euro symbol from java 1.6 to oracle 10.2.0.4.0

database details is as follows
NLS_CHARACTERSET =WE8ISO8859P1
NLS_NCHAR_CHARACTERSET = AL16UTF16
text column type =NVARCHAR2
i am using set
Array p1arr = new ARRAY(desc1, connection, texts);
and
cst.setArray(textIndex, p1arr);
i am using classes12.jar and ojdbc14.jar
is giving excepting like Cannot map Unicode to Oracle character.

Why can't you use the 11.2 drivers? They are certified with 9.2.
The only solution I can give you for older drivers is to give up the array interface and insert the value using setFormOfUse and setString:

  • Problem Inserting Euro Symbol and few others

    We are using java application with oracle 8.1.6 as the db with the charset as WE8ISO8859P15. ALl the forms are using multipart request. We cannot do away without that. When trying to insert euro symbol and few other western european characters, they get converted to something else before getting stored in the db and so we are not able to display them properly on retrieval.
    Can anyone please help in this direction?

    Just set the nls_charset.zip in classpath and then try to insert into db.I think it might not be a problem with database.(note. if u insert euro character it will be reside in db, as some format but u retrive it and stream it thru servlet it will be displayed in the browser properly, if u write using printwriter then it might give "?" / "O" in browser. refer http://www.inter-locale.com/faq/blacksquares.jsp).

    So, it got compiled successfully but when i execute it gives me error as:

    What does this mean?
    So I browse through forum & i got to know that i need to initial the UTL_FILE_DIR ="C:/OracleProject" in init.ora
    So can i edit the init.ora with notepad.When i tried to do that it says permission denied
    In my system it shows the init.ora file in path C:\oraclexe\app\oracle\product\10.2.0\server\config\scripts
    but there is also other file initXETemp in the same path do i need to do the changes in it.
    I have tried even editing the SPFILE as mentioned below:
    C:\oraclexe\app\oracle\product\10.2.0\server\dbs\SPFILEEXE - I had edit this file using notepad & set the value of UTL_FILE_DIR ="C:/OracleProject". So next time when i restarted i'm unable to log on to the database.
    So i had reinstall the software again.
    Could you please let me know how to proceed..

  • How to insert select columns from one internal table to another

    Hi,
    How to insert select columns from one internal table to another based on condition as we do from a standart table to internal table.
    regards,
    Sriram

    Hi,
    If your question is for copying data from 1 int table to other ;
    we can use
    APPEND LINES OF it_1 TO it_2.
    or if they have different columns then:
    loop at it_1 into wa_it1.
    move wa_it1-data to wa_it2-d1.
    apped wa_it2 to it_2.
    clear wa_it2.
    endloop.

  • How to insert a value from sequence in Bussiness Components?

    How to insert a value from sequence in Bussiness Components?
    I would like to do it, but without a triger that would do it before insert.
    I know that there is a type DBSequence in BC where you can insert a sequence name but it does not work when I type there my sequence name.
    Do you now how to fix that problem?
    Bart.

    The newer way to do it is to make the type DBSequence and enter the name of the Sequence object in the sequence field. It must match the same name of the sequence object in the database. Next, you have to create a before insert for each row trigger on the table. Basically, something like this:
    CREATE OR REPLACE TRIGGER TGB_THEME_SEQ
    BEFORE INSERT ON THEME
    FOR EACH ROW
    DECLARE
    BEGIN
    -- Assign the id from the sequence if null
         IF( :new.theme_id IS NULL ) THEN
              SELECT THEME_ID_SEQ.nextval
              INTO :new.theme_id
              FROM dual;
         END IF;
    END;
    In the above example, THEME_ID_SEQ is the seuence object name in the database. If you have the name right but it still fails, then the user you are logging in as probably doesn't have access to the sequence in the database.
    Hope this helps.

  • 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,

    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.
