• Cannot load the file DOC ID 109095.1 java stored procedure

  Hello. I'm trying to follow the documentation for 109095.1 (How to perform a system call to a Java Stored Procedure and capture the output) and after I try to load the java file I received the following two errors below. In some of the forum posts I met and performed various controls as well and from what I can tell, it seems that the java install my have broken or is not installed properly in the first place (unknown previous state). Some of the results of the checks are also lower.

  There are other tables with stored java information but I'm unable to find those queries I has used last week. I do remember every time they were ran zero rows were returned. I will try and get that information. Any assistance is much appreciated thank you.

  Thank you! That seemed to be the case because I had to install java in the database running the two files below sql. I also ran select it under check that java has not been installed. After installing both .sql files, I was able to download my java files successfully.

• Re: "insufficient privileges" error when you run the Java stored procedure in another schema

  I get an "insufficient privileges" error when you run the Java stored procedure in another schema, see details below.  I don't know what are missing privileges (I already granted the EXECUTE privilege), suggestions?  -Thank you.

  Define a simple java class and deploy it as a Java stored procedure to test:

  
  

  Schema: User1

  test of the package;

  public class HelloWorld {}

  public HelloWorld() {

  Super();

  }

  public static String Hello () {}

  Return "HELLO";

  }

  }

  CREATE or REPLACE FUNCTION HELLO RETURN VARCHAR2 AUTHID CURRENT_USER AS LANGUAGE JAVA NAME ' test. HelloWorld.hello () return java.lang.String';

  Grant execute on USER2 HELLO

  Test the Java stored procedure through the PL/SQL function call (in the same schema):

  
  

  Schema: User1

  SET SERVEROUTPUT ON

  DECLARE

  v_Return VARCHAR2 (200);

  BEGIN

  v_Return: = User1. HELLO;

  DBMS_OUTPUT. Put_line ('v_Return =' | v_Return);

  END;

  anonymous block filled

  v_Return = HELLO

  Test the Java stored procedure through the PL/SQL function call in a different pattern:

  
  

  Schema: USER2

  SET SERVEROUTPUT ON

  DECLARE

  v_Return VARCHAR2 (200);

  BEGIN

  v_Return: = User1. HELLO;

  DBMS_OUTPUT. Put_line ('v_Return =' | v_Return);

  END;

  Error report-

  ORA-01031: insufficient privileges

  ORA-06512: at "User1." HELLO', line 1

  ORA-06512: at line 4 level

  01031 00000 - "insufficient privileges".

  * Cause: An attempt was made to change the user name or password

  without the privilege appropriate. This error also occurs if

  trying to install a database without the need for employment

  access privileges.

  When Trusted Oracle is configure in DBMS MAC, this error may occur

  If the user has been granted the privilege necessary for a higher label

  that the connection is active.

  * Action: Ask the database to perform the operation or grant administrator

  the required privileges.

  For users Trusted Oracle get this error, well that granted the

  the privilege that is suitable for the top label, ask the database

  administrator to grant the privilege to the appropriate label.

  You have created the function with AUTHID CURRENT_USER, which means that the function is executed with the rights of the applicant (but not with the rights of the author). This means that the applicant must have grants (directly or through roles) on all used/accessible objects in the service. In your case the user USER2 has not granted with EXECUTE on the class/source Java test. Class HelloWorld, causing the ORA-01031 exception. You create service without AUTHID CURRENT_USER (i.e. with AUTHID DEFINE, which is by default, if you do not have a specific reason to use AUTHID CURRENT_USER) or grant EXECUTE on JAVA test SOURCE. Class HelloWorld to User2.

• The JNI in Java, stored procedure call

  Dear,
  I want to know how to call stored procedure JNI Java. How to configure my java.library.path in Oracle to get a specific directlry containing DLLs file inorder to System.loadLibrary ("< dll_file_name >");

  Not sure if I'm on the right track, but it seems that Oracle does not support JNI.

  http://download.Oracle.com/docs/CD/B19306_01/Java.102/b14187/chthree.htm#CACFCDJF

  
  Oracle database does not support the use of JNI in Java applications. If you use JNI, then your application is not 100% pure Java and native methods need porting between platforms. Native methods can result in a server crash, violating the security and corrupted data.

  I'm a PL/SQL programmer, but not a Java programmer. I have the following java function that does what it's supposed to add a pdf at the end of another pdf document:

  import oracle.sql.BLOB;
  import org.apache.pdfbox.util.PDFMergerUtility;
  import oracle.jdbc.OracleConnection;
  import oracle.jdbc.driver.OracleDriver;
  import java.io.OutputStream;

  public static BLOB appendPDF(BLOB pdfdoc1, BLOB pdfdoc2) throws Exception {
         
          //create a connection object to the current instance
            OracleConnection conn = (OracleConnection)new OracleDriver().defaultConnection();
          //create the output blob using the connection
            BLOB outPDF = BLOB.createTemporary(conn, true ,BLOB.DURATION_SESSION);
          //create an output stream to the output blob
            OutputStream os = outPDF.setBinaryStream(0);               
          //instantiate the pdf merger utility
            PDFMergerUtility mergerUtility = new PDFMergerUtility();       
          //connect the merger to the output stream
            mergerUtility.setDestinationStream(os);
          //stream from each input blob into the merger utility
            mergerUtility.addSource(pdfdoc1.getBinaryStream());
            mergerUtility.addSource(pdfdoc2.getBinaryStream());
          //merge the 2 input pdfs
            mergerUtility.mergeDocuments();             
          //do not close the output stream
          //return the blob
          return outPDF;
      }
  
  }
  

  CREATE OR REPLACE package PDFTOOLS.pkg_pdf_utilities
  as
  function f_get_merged_pdf (
            pi_pdf1       blob

  It's very basic, but doesn't seem to work. However, I want to my function from PL/SQL to a procedure that looks like this:

  CREATE OR REPLACE package PDFTOOLS.pkg_pdf_utilities
  as
  procedure sp_append_pdf (
            pio_pdf2append2   IN OUT NOCOPY blob
          , pio_pdf2append   IN OUT NOCOPY blob
    )
  end pkg_pdf_utilities;
  /
  

  What is important, what I'm trying to do is to NOCOPY the BLOBs. Otherwise, I have to read my PDF files into 2 BLOBs and create a 3rd blob as output. I prefer to be able to keep the pio_pdf2append2 as the final output. What I actually do call thing in a loop to gradually add a PDF file to a big. I'm not linking this in one operation because of concerns over the use of the system and because the pdfbox library java has would have been question after 850 in PDF format, which is not completely unrealistic in my approach.

  How could I achieve this?

• Impossible to use Java stored procedure java.nio.file package

  Hello

  I want to use the classes in the java.nio.file package but I have the problem that the classes are not loaded in the database (oracle 12 c with jvm) installed. I can't put my class in the database and use it in my procedure. It is always invalid because of the java.nio.file dependencies. Is it possible to load the java.nio.file package for use in my PB? I tried to load it via loadjava but then I get the error ORA-29552 java.lang.SecurityException: prohibited package name: java.nio.file.

  Thank you and best regards,

  Kai

  Java.nio.file package is available starting with Java 1.7, while Oracle 12 c JVM is 1.6, simple as that.

• script can be invoked only from a java stored procedure

  I made a java procedure and called via a sql procedure that accepts a string input:
  
  the string is passed to Runtime.getRuntime () .exec ("myString");
  
  
  If this string is:
  RM-f /test/test22.log
  
  proc = Runtime.getRuntime () .exec ("rm-f /test/test22.log");
  
  the test22.log file that is located in the test folder is deleted
  
  but when I place the order. /test/batchstart.ksh to run a script, the script does not run.
  
  proc = Runtime.getRuntime ().exec(".) (' / test/batchstart.ksh ");
  
  
  received the permissions of files and also the rights of the executables.
  
  If some bobdy can say why the script is not running which will be a great help

  Hello

  I had the chance to do something like the following without using oraenv

  ORACLE_SID = GNVDEV
  ORACLE_HOME=/U21/app/Oracle/product/10.2.0/Db_1/

  PATH = / usr/local/bin: $ORACLE_HOME/bin: $PATH
  export PATH

  In some cases affecting LD_LIBRARY_PATH to include the libs oracle was also necessary.

  Another option is to simply use the full paths everywhere for example use
  $ORACLE_HOME/bin/sqlplus instead of just sqlplus.

  Hope this helps,
  Ravi.

• Java - a stored procedure with call by result

  Hi the Oracle community,

  I'm looking for some example Code how to use a Java-Stored procedure with output parameters. Don't get me wrong. I don't want to call a procedure with the parameters Out of Java (there are many examples in this respect over there). I want to just implement the appeal of the concept of results in a Java-Stored procedure. A customer calls this procedure with certain parameters and the Java procedure will fill the. So my first question: is it possible? And my second Question: how to implement it?

  Greetings.

  I found a solution. It's very simple.

  Just setting the parameters as java array (e.g., String() P1). The first value (P1 [0]) is the returned value.

  Finally just contained JDeveloper in dialog box "Edit method Signature" the parametermode OUT.

  The dialog box are entitled on the stored procedure in the dbexport file. You can read this

  in Section 6, publishing Java Classes with call specifications-> defining the Modes parameter in

  The Oracle database Java Developer's Guide.

  A correction preceding: "for the case on the information in the TABLE of the DataSet to be targeted on each node is also sent for the tag requests will target only this dataset (and avoids duplicates).»

  should read "in the case of on TABLE query Tags will only target the local primary data on the node for tables partitioned, while for replicated tables, it is sent to only one of the lines (and so avoids duplicates in both cases).» WHERE clause to TABLE is not used for cutting data only for the size of the set of nodes to the target.

  The tag prunes yet the query to all of the local primary buckets in all cases (i.e. which WE ALL and on GROUPS of SERVERS) so the comment about and equivalent was incorrect. However, this will always be looking for data in duplicate for replicated tables and TABLE is the only way to avoid it for now.

• Java stored in oracle

  Hello
  It is with regard to the java stored procedure.
  I wrote a java stored procedure for the dissemination of the DB. But it needed subsidies or additional privileges to be run from the database.
  Can someone please explain what are the necessary subsidies for it.
  
  I have to give to the following permissions to java methods...
  
  dbms_java.grant_permission(User,'java.util.PropertyPermission','*','read');
  dbms_java.grant_permission (user, 'java.net.SocketPermission','* ',' connect, determination ');
  dbms_java.grant_permission(User,'java.) IO. FilePermission ', FilePathName,' read');
  
  
  Can someone please explain what are the privileges necessary for execution of the foregoing. Because I tired it with normal privileges... it does not work...
  
  I get the following error when running it from the normal user... rather, the user that was created for me...
  
  ORA-29532: Java call terminated by eception Java exception: java.lang.SecurityException: update of table political SYS:java.util.PropertyPermission, *.

  Hi Anirban,

  You can run these commands in SQL * MORE or a PL/SQL Developer command window.

  exec dbms_java.grant_permission(user,'java.util.PropertyPermission','*','read');
  exec dbms_java.grant_permission (user, 'java.net.SocketPermission','* ',' connect, determination ');
  exec dbms_java.grant_permission (user, 'java.io.FilePermission', FilePathName, 'read');

  If you don't have enough privilege to do these, you try to use the system account or sys.

  Best regards

  Pass the String [] as an argument to mainbook():

  create or replace PROCEDURE openpdffile

  Do you have posted on the forum of the database?

• Passing an array as a parameter of java (java controls) for the stored procedure

  Hello

  Try using an oracle.sql.ARRAY with a nested table or varray instead of a table index. Create the type SQL and Java object as follows

      SQL> create type sl_tab as varray(3) of integer;
      Java:
          ArrayDescriptor ad = ArrayDescriptor.createDescriptor
              (".SL_TAB", java.sql.Connection);
          Object elements = new Object[3];
          elements[0] = new Integer(12);
          elements[1] = new Integer(13);
          elements[2] = new Integer(14);
          oracle.sql.ARRAY array =
              new oracle.sql.ARRAY(ad, oracle.jdbc.OracleTypes.ARRAY, elements);
          SQLParameter[] params = new SQLParameter[1];
          params[0] =
              new SQLParameter(array, oracle.jdbc.OracleTypes.ARRAY, SQLParameter.IN);
          String succ = dbControl.testFunc(params);
  

  I don't think that you can pass an array of Java, this is why you have more success using an oracle.sql.ARRAY with a SQL varray. -Michael-

• Called Java overloaded with stored procedures

  I have two stored procedures with the same name and the same number of parameters. They are overworked because the two procedures differ in the data type of their parameters. In addition, there are 2 2 parameters and the other has 3 in and 1 OUT parameter.
  
  But Java has problem describing as Java is unable to distinguish that they are two different procedures. How Java should treat calling them? I don't want to change their name.
  
  Thank you

  What you are referring is named notation, a way to specify an argument name with its value instead of associating the argument which the variable position value in the call. Given that the appeal should be processed through SQL and just be text to Java try to use named notation in the appeal of Java like you did in Oracle directly and see if it works. If it does not try to use the wrapper procedure I described.
