ORA-29532: Java call terminated by eception Java exception:... NoSuchMethodEr

Hi all

I got this error: ' * ORA-29532: Java call terminated by eception Java exception: java.lang.NoSuchMethodError * "when I run a Java function I in Oracle.

I had two methods in a class. (I used Eclipse to develop)

public class StringHelper {}
public static String wordCap (String source) {}
int len;
Char [] tanks;
Len = source.length ();
Boolean capnext;
String src;
char onechar;
If (len == 0) {}
return the source;
}
SRC = source.toLowerCase ();
tanks = src.toCharArray ();

capnext = true;
for (int i = 0; i < len; i ++) {}
OneChar = characters;
String Schär = Character.toString (onechar);
If (! isAlpha (Schär)) {}
The following letter should be capitalized.
capnext = true;
} else {if (capnext)
Capitalized this alphabetical character.
the characters [i] = Character.toUpperCase (onechar);
The following character should not be capitalized.
capnext = false;
}
}
String res = new String (tanks);
return res;
}

public static String quote (String source) {}
{if (source. IsEmpty())}
return the source;
}
String newsrc = '-' "+ source + ' \;"
return newsrc;
}
}

Load the Java in Oracle, I used:

loadjava-username/password user name - address StringHelper.class

Check the status of the compilation and load, in SQL * more: (I use Oracle 10 g)

SQL > select object_name, object_type, status
2 from user_objects where object_type like '% of JAVA;

OBJECT_NAME
---------------------------
OBJECT_TYPE STATUS
------------------- -------
OneStringHelper
VALID JAVA CLASS

Created the wrapper:

CREATE OR REPLACE FUNCTION ONEADM. FN_WORDCAP(WORDS IN VARCHAR2) RETURN VARCHAR2
IN THE JAVA LANGUAGE
NAME "java.lang.String StringHelper.wordCap (java.lang.String) return;
/

CREATE OR REPLACE FUNCTION ONEADM. FN_QUOTE(QUOTEW IN VARCHAR2) RETURN VARCHAR2
IN THE JAVA LANGUAGE
NAME "java.lang.String StringHelper.quote (java.lang.String) return;
/

The two functions created successfully.

Then, finally, by calling the function:

SQL > SET SERVEROUTPUT ON
SQL > dbms_java.set_output CALL (50);

The FN_WORDCAP function have no error:
SQL > SELECT FN_WORDCAP('my test') FROM DUAL;

FN_WORDCAP ('MYTEST')
-------------------------------------------------------
My Test

But, the FN_QUOTE function:
SQL > SELECT FN_QUOTE ('mine') FROM DUAL;
SELECT FN_QUOTE ('mine') OF DOUBLE
*
ERROR on line 1:
ORA-29532: Java completed by eception Java exception appeal:
java.lang.NoSuchMethodError

Are there measures, the program installation or something I missed?

Thanks in advance for your help :)

Hello

[java.lang.String #isEmpty (): http://java.sun.com/javase/6/docs/api/java/lang/String.html#isEmpty ()] is available since Java 1.6. Version Java from Oracle last is 1.5 to 11 g. You should not use this method.

And BTW, why do you need this StringHelper?

  • The simple geometry Gets the error ORA-29532 on all calls SDO_GEOM

    Hi all

    I have a single point in a table in such a way that the query:
    select SDO_GEOM.VALIDATE_GEOMETRY(geomObj, 0.05) from testvalid;
/* Returns */
SDO_GEOM.VALIDATE_GEOMETRY(GEOMOBJ,0.05)
'TRUE'
    However the query:
    select SDO_GEOM.VALIDATE_GEOMETRY_with_context(geomObj, 0.05) from testvalid;
    Receives the following error message:
    ORA-29532: Java call terminated by uncaught Java exception: java.lang.NumberFormatException: empty String
ORA-06512: at "MDSYS.SDO_3GL", line 658
ORA-06512: at "MDSYS.SDO_GEOM", line 519
ORA-06512: at "MDSYS.SDO_GEOM", line 558
ORA-06512: at line 1
    The data itself are a unique SDO_POINT_TYPE:
    select GEOMOBJ from testvalid;
/* Returns: */
GEOMOBJ
'(3001, , (174.092329032787, 129.420551704918, -71.2857142857142), , )'
    I think the problem is something to do with the accuracy of the stored X, Y and Z values in point because if I'm running the following:
    update TESTVALID set GEOMOBJ.sdo_point.x = cast(GEOMOBJ.sdo_point.x as number(8,3));
select SDO_GEOM.VALIDATE_GEOMETRY_with_context(geomObj, 0.05) from testvalid;
/* Returns: */
SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(GEOMOBJ,0.05)
'TRUE'
    Similarly, running a direct comparison of an object made in the textual representation of the point fly works fine:
    select SDO_GEOM.VALIDATE_GEOMETRY_with_context("MDSYS"."SDO_GEOMETRY"(3001,NULL, "MDSYS"."SDO_POINT_TYPE"(174.092329032787,129.420551704918,-71.2857142857142),NULL,NULL), 0.005) from dual;
/* Returns */
SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT("MDSYS"."SDO_GEOMETRY"(3001,NULL,"MDSYS"."SDO_POINT_TYPE"(174.092329032787,129.420551704918,-71.2857142857142),NULL,NULL),0.005)
'TRUE'
    Note that I only noticed this problem after upgrade to v11 v11 R2. In addition, the same error ORA-29532 happens when executing calls SDO_GEOM. [x] function such as SDO_GEOM. DISTANCE(). The problem is not limited to the geometries of type SDO_POINT_TYPE, but the problem only happens on some geometry entries in my database. It is reproducible in that the same geometry will continue to fail and the only solution I found is to try to round up its precision in x, y or z. I don't know how to round the precision for the types of SDO_POINT_TYPE easily, so one of my problems is that I find myself with a any dispersion of other geometries that I can query is no longer in space.

    The data itself was inserted from MATLAB (which connects using drivers of ODBC Oracle Java v11) which converts my details in Java.Math.BigDecimal and binds to a prepared statement oracle.
    It is possible that I consider that the insertion is made from different computers, some of which are 64-bit computers. Maybe somehow these machines are pumping in too large of a precision coordinates for the geometry of the oracle?

    Any help would be great I am quite lost here.
    If the precision is indeed the problem, anyone know how can I cut these surplus values after the decimal point for all types of geometry?


    Thank you
    Sven.

    It is only related to the version of the server.
    So once the database is 11.2, that corruption won't happen.

  • Running command OS of PL/SQL: ORA-29532

    Hi all

    I have created a java program loaded in the database using loadjava utility and finally gave grant execute in public. Then do a wrapper function to call inside as below:

    FUNCTION fn_OSCommand_Execute (STRING command)

    RETURN NUMBER

    IS

    JAVA LANGUAGE

    NAME 'OSCommand.Execute (java.lang.String) return java.lang.int;

    Connected to SYS and gave the following gloves Scott using dbms_java

    declare

    v_key NUMBER;

    Start

    DBMS_JAVA. GRANT_PERMISSION ('SCOTT', 'SYS:java.io.FilePermission', '< < ALL_FILES > >', ' read, write, execute, delete, v_key);

    DBMS_JAVA. GRANT_PERMISSION ('SCOTT', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', ", v_key);

    dbms_java.grant_permission ("SCOTT", "SYS:java.io.FilePermission", "c:\windows\system32\cmd.exe", "run", v_key);

    COMMIT;

    end;

    When calling the function, I get the below error:

    I run on the platform of Windows7 & Oracle 12 c 64 bit version.

    Waiting for all of your expert advice.

    Yes, my Oracle server is installed on Windows 7.

    In fact, the user (SCOTT) missed soome network ACL. I solved it by giving the connect, solve network ACL for the requested host as below:

    BEGIN

    DBMS_NETWORK_ACL_ADMIN. CREATE_ACL (acl-online 'dbserver.xml',

    Description-online 'DB server ACL. "

    principal-online "SCOTT."

    The Java Exception: java.lang.reflect.InvocationTargetException: during the java.lang.reflect.Method .invoke call.

    I came across the same thing as you. I did a lot of experimenting and found it works:

    var result = (function() {
    var ReflectiveArray = java.lang.reflect.Array;
    var CreateSQL = Packages.PeopleSoft.PeopleCode.Func.CreateSQL;
    var columns = ReflectiveArray.newInstance(java.lang.Object, 1 /* number of selected columns */);
    var results = [];

    SQL = CreateSQL("SELECT OPRDEFNDESC FROM PSOPRDEFN WHERE ROWNUM < 10");
    while (SQL.Fetch(columns)) {
        results.push(columns[0]);
    }

    return results.join();

}());

    He seems to have been a problem with translation between the JavaScript array and the Java array Object []. I solved this by using java.lang.reflect.Array.newInstance to create a new instance of the object [1].

    Next issue to deal with is your memory problem. In the error message, it seems to have something to do with the Garbage Collection and a lot of temporary objects. You declare you line and cell by using the var =... line and cell var =...? If not, then they are in the global namespace and properties of the global object. At the end of each iteration of the loop, use delete line and delete cells. If you declare the var, then set their value null at the end of each iteration. Based on your code, I expect each time through the loop would decrease the number of references, but I saw where setting explicitly using null. The only other temporary object I see is the value in the table. Just for fun, I added this at the end of each loop, and he ran very well:

    columns[0] = null;

    You can use temporarily the 11.1.2.2 frmwebutil.jar file (do not use an old), but I don't recommend this doing in the meantime support to provide a proper fix.  I also recommend carefully test your application if you plan to use this temporary fix in production.  Contact the Oracle Support to request a suitable patch.

  • My first problem of java exception program (helloworld)

    Hello

    I am very new to java programming for blackberry, and I read an e-book - blackberry for beginners.

    OK, for the moment... I currently have 3 files in/src /...

    HelloWorldApp.java

    package com.beginningblackberry;

    Import net.rim.device.api.ui.UiApplication;

    SerializableAttribute public class HelloWorldApp extends UiApplication {}

    public HelloWorldApp() {}
    TODO auto-generated constructor stub
    Screen HelloWorldMainScreen = new HelloWorldMainScreen();
    pushScreen (mainScreen);
    }

    /**
    @param args
    */
    Public Shared Sub main (String [] args) {}
    TODO self-generating method stub
    HelloWorldApp app = new HelloWorldApp();
    app.enterEventDispatcher ();
    }

    }

    -------------------------------------

    HelloWorldMainScreen.java

    package com.beginningblackberry;

    Import net.rim.device.api.ui.component.LabelField;
    Import net.rim.device.api.ui.container.MainScreen;

    SerializableAttribute public class HelloWorldMainScreen extends form {}
        
    private LabelField labelField;
        
    public HelloWorldMainScreen() {}
    LabelField labelField = new LabelField ("Hello World");
    Add (labelField);
    Thread MainScreenUpdaterThread = new MainScreenUpdaterThread (this);
    thread. Start();
    }
        
    {} public void appendLabelText (String text)
            
    labelField.setText (labelField.getText () + "\n" + text);
    }
    }

    ---------------------------------------------------

    MainScreenUpdaterThread.java

    package com.beginningblackberry;

    Import net.rim.device.api.ui.UiApplication;

    SerializableAttribute public class MainScreenUpdaterThread extends Thread {}
        
    HelloWorldMainScreen screen;
        
    public MainScreenUpdaterThread (screen HelloWorldMainScreen) {}
    this.mainScreen = screen;
    }

    public void run() {}
    for (int i = 0; i)< 10;="" i++)="">
    try {}
    Thread.Sleep (5000);
    } catch (InterruptedException ex) {}
    }
                
    Queue a task on the event thread
    UiApplication.getUiApplication () .invokeLater (new Runnable() {}
    public void run() {}
    mainScreen.appendLabelText ("Update");
    }
    });
    }
    }
    }

    ----------------------------------------------------

    Okay, that's all the code I wrote so far according to the book it should display "Hello World" - and he does, but when 5 s passes, I get an error 104 of the JVM, the null eception exception pointer, but he should update my screen with "Update" every 5 seconds.

    I am writing my code word by Word, to learn as much as possible, but I have no idea how to solve this problem yet

    any advice would be greatly appreciated.

    BR

    It is here:

    public HelloWorldMainScreen() {}
    LabelField labelField = new LabelField ("Hello World");
    Add (labelField);
    Thread MainScreenUpdaterThread = new MainScreenUpdaterThread (this);
    thread. Start();
    }

    local variable hides the field from the class. Replace:

    public HelloWorldMainScreen() {}
    labelField = new LabelField ("Hello World");
    Add (labelField);
    Thread MainScreenUpdaterThread = new MainScreenUpdaterThread (this);
    thread. Start();
    }

  • BlackBerry Smartphones Java exception

    Just tried to open the world Ap on my Bold 9700 and have an error message and cannot access App world.

    Eception exception: java.lang.NoclassDefFoundError

    Any ideas on how to solve this problem?

    Thank you

    Start with a battery pull. With your phone, remove the battery and then replace it. If it does not, reload the OS of your phone using BlackBerry Desktop Software.

    I hope that helps you.

  • Errors in mode silent netca with java exception

    I have installed Oracle on RHeL 6.4 11.2.0.3 and have a few problems with the installer, netca.

    Unfortunately, it is a bit difficult because we do not have X 11 libraries to run in GUI mode.

    So I run the netca using the response file:

    Basically, the parameters I put are:

    SHOW_GUI = false

    «Log_file=""/Oracle/product/11.2.0.3/Network/Tools/log/netca.log «»

    INSTALL_TYPE = "«typical"»

    LISTENER_NUMBER = 1

    LISTENER_NAMES = {'LISTENER'}

    LISTENER_PROTOCOLS = {"TCP; 1521"}

    LISTENER_START = "'LISTENER '.

    NAMING_METHODS = {"TNSNAMES", "ONAMES", "HOSTNAME"}

    NSN_NUMBER = 1

    NSN_NAMES = {'EXTPROC_CONNECTION_DATA'}

    NSN_SERVICE = {'PLSExtProc'}

    NSN_PROTOCOLS = {'TCP; HOST NAME; 1521 "}

    Then, I run the command as follows: / Silent netca /responsefile = / netca.rsp < path >

    When I run it, it gives: error: 2. check the trace for details file... and then Oracle Net Services configuration failed.  The exit code is 1

    Here are the trace file, the main error at the end.

  • CouponPrinter.exe does not work. I can download and run the program, but does not, print already added the file name to the list of java exceptions

    running windows xp, update java 7 51, norton antivirus says file is ok, please help

    HI DJDOLLARROB,

    Thanks for posting, as you might expect, there are troubleshooting you can undertake to check why the download does not work. It is highly possible that the source that you have downloaded from cannot be no longer works. Is there a site that you can check to see if it does not work for them either? Also where it is downloaded from?

    Otherwise please see if scanitemswhendone is enabled: change what Firefox does when you click on or download a file

    If download hangs at the last minute (just before reaching 100%), the cause may be an antivirus software that tries to parse the file and during this process the instance of Firefox crashes.

    To resolve the issue, try disabling the analysis as follows:

    1. In the address bar, type Subject: config and press enter. The subject: config "this might void your warranty!" warning page may appear.
    2. Click on I'll be careful, I promise!, to continue on the subject: config page. A list of parameters must appear
    3. Filter the list by typing in the search bar at top. Enter scanWhenDone. Now you should find the "browser.download.scanWhenDone" preference.
    4. Double-click this preference to set the value to false.
    5. Then, try to download something and see if it still crashes.

    Please reply and let us know if this helped you!

  • Java exceptions

    Hello
    I use HttpsURLConnection class and when I access a page get the exception ' java.io.IOException: server returned HTTP response code: 500 for URL.
    I would like to be able to read the "input" variable (BufferedReader) even when I get this exception.
    It is possible to skip an exception?

    try {}
    Ins InputStream = con.getInputStream (); the exception is triggered by this line
    InputStreamReader isr = new InputStreamReader (ins);
    BufferedReader in = new BufferedReader (isr) entry; I want to read this input variable
    } catch (Exception exception) {}
    exception.printStackTrace ();
    }

    Thank you.

    HttpURLConnection.getErrorStream () seems to be what you need (in the catch block).

  • Java: Exception in thread "AWT-EventQueue-0".

    Hello
    I created a little program in Java Swing & Oracle DB.
    The program is for a small business in the field of logistics, such as DHL...
    In a section, I select a table, a few columns containing a condition, that the content in a column to be: ENVELOPE, PACKAGE, or both.
    Now, when the condition is the request ENVELOPE is OK, even when both; but when the selection = PACKAGE I get the following error:

    P.S. I'm kinda big beginners to Java, then please explain what you say! Thank you.
    Moreover, the request is OK, because the result I put him in a Swing JTable, but also create a HTML file with the table, wich is OK.

    for example, in the method:

    Replace this:
    Return getValueAt (0, c) .getClass ();

    with this:
    Object value = getValueAt (0, c);
    return value! = null? value.getClass (): String.class;

    or if you know which column of the table, what type of data should display, you can do the following:
    If (c == 0) {}
    Return Integer.class;
    } else if (c == 1) {}
    Return String.class;
    } else...

    A little explanation: getColumnClass() is typically implemented as in your case - access table with the values and returns the class of the 'c' in the first row column
    This must be done when you are sure that this table is not empty, and it seems that this has caused your problem (empty array with values).

    Hope that helps

    Hello

    It must explicitly mention batch while the file configuaring adapter.
    that is in step 5: check the file contains several messages and mention how many messages you want to process in a batch.
    i.e. If you have 10000 msgs in your file about the size as 500. Then, it will read 10000 records in 20 lots.

    Now while writing to a file, use Append = true property.
    You must add this property to fileadapter.wsdl (in jca:operation tag) that is created when you have completed the registration of the file with the write operation adapter.
