Java Stored Proc, passing BLOB, not stored in a table.

I have checked this article, and found it will not suit my needs.
I have even looked at the 4 articles on the "JSP How-To Documents" page.
I need to pass in a BLOB to my Java Stored proc, but not store it in the DB - My java code manipulates the LOB and it should never go into the DB. I know I could do the normal store, get an id and pass to my JSP... but that is a poor way to implement this. Are there any code samples on how to do this please ?

WOW! That seems like a very bad design.
Is it just the compiler that has the problem or is the PL/SQL code inside the stored procedure also affected? For example, if I'm doing an
EXECUTE IMMEDIATE 'insert ... INTO OtherSchema.tblTest';
Is this going to be a problem?
The problem with granting the access explicitly is the Archive Schema, which has the stored procedure that is failing, might not exist at the time when the other schemas are created. Therefore, there is no user to grant permissions to. I solved this by granting permissions to the role and when the archive user is created it is assigned that role.
This seems like the proper way to solve this problem.

  • How to pass a refcursor to a java stored proc

    Hi all,
    Please forgive me as I am new to Java and JDeveloper....
    I want to pass a refcursor to a java stored proc. Does anyone know how to accomplish this?

    As Avi has indicated, you can map ref cursor to java.sql.ResultSet
    here are Call Specs and a code snippet from chapter 3 in my book.
    procedure rcproc(rc OUT EmpCurTyp)
    as language java
    name 'refcur.refcurproc(java.sql.ResultSet[])';
    function rcfunc return EmpCurTyp
    as language java
    name 'refcur.refcurfunc() returns java.sql.ResultSet';
    * Function returning a REF CURSOR
    public static ResultSet refcurfunc () throws SQLException
    Connection conn = null;
    conn = DriverManager.getConnection("jdbc:oracle:kprb:");
    Statement stmt = conn.createStatement();
    ResultSet rset = stmt.executeQuery("select * from EMP order by empno");
    // fetch one row
    if (
    System.out.println("Ename = " + rset.getString(2));
    return rset;

  • Java.util.PropertyPermission...not granted to ProtectionDomain(Stored Proc)

    I'm trying to develop a java stored procedure on Oracle 10.1.2 that makes use of many other libraries, (Axis, WSIF, custom libs), and I'm stuck on this permissions error. I've loaded all of the libs into the same schema under the same user, (with JAVA_ADMIN), and several other privileges. I loaded the files using the following command, "loadjava -verbose -debug -recursivejars -genmissing -resolve -time -fileout loadJava.log -user {userID}/{pwd}@{SID} someJar.jar". The error occurs when a call to WSIFProperties.getProperty attempts to access the org.apache.wsif.mapper or org.apache.wsif.mappingconvention properties.
    In a normal java2 environment, I'd simply edit the java.policy file to provide permissions to the codebase (file:/C:/spi4j2.5.4_J2ee1.4/coreLib/fsgWsif1.1.jar). Since Oracle doesn't have ProtectionDomains, if I add read permissions for those properties using the following command, "call dbms_java.grant_permission( 'SCHEMANAME', 'SYS:java.util.PropertyPermission', 'org.apache.wsif.mapper', 'read' )", it seems as if all of the other classes in the schema should be able to read the property, right? It appears the logfile dump below is showing the permissions that the classloader recognizes. Where did he get those? If they came from the DBA_JAVA_POLICY view, then why can't it pick up on the fact that I've granted read permission to the property it's trying to read? When I tried loading the classes without using the -recursivejars option, I got all kinds of ClassDefNotFound errors and couldn't even start the program, (I guess because it'd loaded the other jars as resources instead of unpacking the classes, the resolver couldn't look into the jars and locate the classes that it needed). The program works just fine outside of the database, (even without me adding read permissions for the codebase to access the properties in the java.policy file). Any help would be greatly appreciated. Thanks in advance.

    Iam passing an array of objects from Java to the C
    file. The total size of data that Iam sending is
    around 1GB. I have to load this data into the Shared
    memory after getting it in my C file. Iam working on
    HP-UX (64-bit). Everything works fine for around 400MB
    of data. When I try to send around 500MB of data, the
    disk utilization becomes 100%, so does my memory
    utilization and I get a "Not enough space" when I try
    to access shared memory. I have allocated nearly 2.5GB
    in my SHMMAX variable. Also, I have around 45GB of
    disk free. The JVM heap size is also at 2048MB. Where did you get the 400/500 number from? Is that the size of the file?
    What do you do with the data? Are you doing nothing but copying it byte for byte into shared memory?
    If yes then a simple test is to write a C application that does the same thing. If it has problems then it means you have an environment problem.
    If no then you are probably increasing the size of the data by creating a structure to hold it. How much overhead does that add to the size of the data?

  • XML Parsing in Java Stored Proc--Oracle XML Support Installation?

    I am working with a third party product that is having difficulty running a java stored proc that is parsing a supplied XML file. The proc basically looks like:
    import javax.xml.parsers.DocumentBuilder;
    import javax.xml.parsers.DocumentBuilderFactory;
    import javax.xml.parsers.FactoryConfigurationError;
    import javax.xml.parsers.ParserConfigurationException;
    import org.w3c.dom.Document;
    import org.xml.sax.SAXException;
    InputStream is = getXMLAsInputStream(xml);
    try {
    DocumentBuilderFactory factory =
    DocumentBuilder builder = factory.newDocumentBuilder();
    Document document = builder.parse( is );
    ... parse the document ....
    catch (FactoryConfigurationError e) {
    // unable to get a document builder factory
    We are running on, HP-UX 64-bit. At first, when we would attempt to run the proc, a database hang would occur; now after attempting to install using loadjava jars for xerces2.6: ORA-29532: Java call terminated by uncaught Java exception:
    javax.xml.parsers.FactoryConfigurationError: Provider
    org.apache.xerces.jaxp.DocumentBuilderFactoryImpl not found)
    The vendor says that the errors we are getting when running are not due to any dependency on xerces or jre1.4, and that we need to "install Oracle XML support", but I'm not certain what this means (I cannot find any documentation on what to install). I believe that there are jars that need to be loaded into the database to support the XML parsing, as jre1.3 does not include built-in XML support, and Oracle uses jre1.3.
    So...does anyone have any thoughts as to how to resolve the missing references? Is there a way to "install Oracle XML support", or is it to install the necessary jars?

    The following resources should be of help:
    Oracle9i Database Release 2 (9.2) Documentation Library
    In particular, check out the following:
    Java Developer's Guide
    Java Stored Procedures Developer's Guide

  • Parse XML in a java stored proc

    I am trying to parse an xml document in a java stored procedure. Just following my nose, I have developed a stored proc that works fine in development (outside the database using JRE 1.4.1) using the Xerces 2.5 parser. But, after having transferred the xerces xercesImpl.jar, xmlapis.jar, and my implementation class into oracle using loadjava when I call my stored proc the code throws an exception trying to build the document with an error like:
    NoClassDef exception org.apache.xerces.jaxp.DocumentFactoryBuilderImpl
    My Code looks like this:
    import javax.xml.parsers.DocumentBuilder;
    import javax.xml.parsers.DocumentBuilderFactory;
    import javax.xml.parsers.FactoryConfigurationError;
    import javax.xml.parsers.ParserConfigurationException;
    import org.w3c.dom.Document;
    import org.xml.sax.SAXException;
    InputStream is = getXMLAsInputStream(xml);
    try {
    DocumentBuilderFactory factory =
    DocumentBuilder builder = factory.newDocumentBuilder();
    Document document = builder.parse( is );
    ... parse the document ....
    catch (FactoryConfigurationError e) {
    // unable to get a document builder factory
    The exception caught is a FactoryConfigurtionError.
    I'm not particularly attached to xerces, I'm really just looking for a way to parse XML inside my java stored proc, so any help to solve my problem, or an alternative suggestion will be greatly appreciated.

    I looked again and sure enough the xerces implementation classes were missing. I had run a .cmd file containing these two lines, but it looks like only the first one ran...
    loadjava -u ncc/[email protected] -v -r M:\Database\JavaGeocode\Xerces2_5_0\xml-apis.jar
    loadjava -u ncc/[email protected] -v -r M:\Database\JavaGeocode\Xerces2_5_0\xercesImpl.jar
    Now I've got everything working fine with Xerces!

  • Java Stored Proc Enum Failure

    Is there a problem with all enums called from Java stored procedures? Has anyone gotten this to work?
    Here is the enum:
    public enum OscarType
         public static String hello(){
              return "hello";     
    The client is running jdk 1.6_04. The server is running jdk 1.6_13. We have tried compiling client side and server side. It results in the same error.
    Invoking a stored proc that calls the static method hello results in:
    Error report:
    ORA-29516: Aurora assertion failure: Assertion failure at eox.c:342
    Uncaught exception System error: java/lang/UnsupportedClassVersionError
    ORA-06512: at line 8
    29516. 00000 - "Aurora assertion failure: %s"
    *Cause:    An internal error occurred in the Aurora module.
    *Action:   Contact Oracle Worldwide Support.
    The following query shows the JAVA CLASS OscarType to have a status of VALID.
    SELECT status,object_type,dbms_java.longname(object_name) FROM user_objects
    and dbms_java.longname(object_name)='OscarType';

    Wrong version of Java. 1.6. was not installed on the server. Issue resolved.

  • Java Stored Proc and Oracle

    I have a customer using Oracle 8.0.6 (on multi-platforms). We'll need to implement a pl/sql which needs to execute an external script.
    My understanding is there are only 2 ways to achieve this: (a) use Java stored procedure, (b) use C/C++ library
    Question 1: Is Java Stored Proc available in 8.0.6?
    Question 2: Is there anywhere I can download Oracle 8.0.6 (Windows, or Tru64, Linux)?
    - Will

    java in the database was introduced from Oracle8i onwards. this version of Oracle does not support java virtual machine in the database.
    You would need to use C/C++ external procedures.

  • Java stored proc status

    What would trigger the change of "STATUS" from valid to invalid
    for a java stored procedure (status of the PROCEDURE, not the
    java class/source)?
    - loaded a java source/class
    - published it with CREATE PROCEDURE ...
    - the procedure inserts a row into some table X
    - select* from user_objects where object_type = 'PROCEDURE'; shows that
    the proc is valid
    - call the proc, fine
    - delete a column from the table X
    - select* from user_objects where object_type = 'PROCEDURE'; shows that
    the proc is still VALID
    - call the proc, the call actually completed without error! (but the new row didn't get inserted into the table)
    When the schema of a table that a java stored proc refers
    to changes, will the java stored proc automatically marked
    as "INVALID"? If not, when will this status changed from

    A java stored procedure is marked as VALID or INVALID depending on whether Oracle had any problems loading the class file into the database. Since you had no problems loading the class file it will always be valid.
    Now, after you deleted the column in the table I would assume that the java stored procedure would have a problem when it tried to do an insert and it would throw an exception. Your java stored procedure is VALID, it just isn't executing properly and is more than likely throwing an exception.
    Sometimes an exception thrown from a jsp is written to a log file instead of to the console. I suspect that this is the case in your situation. You think that the call to the jsp executed with no errors, but I bet it didn't. You will probably find the errors somewhere in the oracle\ora90\admin\mydatabase directory. Look at the latest .trc file. (Note: the path I gave to the .trc files may be different depending on what version of oracle you are using).

  • Java stored proc from proxy Java classes generated from a web service?

    Hi gurus,
    I have searched "Java Stored Procedure" on this forum but could not find what I am looking for, so I have to post again.
    I need to use a web service and my client app is written in PowerBuilder 11 (Sybase), which claims that it will create a datawindow from a web service. Well, it turned out that PB can only handle simple stuff (it works with a very simple wsdl from the internet) but can't handle more complex ones that we need to use. So I am thinking about using Oracle JDeveloper(JDev) to create the web service proxy for the web service and then load it into Oracle as a Java stored procedure so that PowerBuilder can call the procedure. JDev succsfully generated the proxy and a few Java classes. My question is, do I need to load all the classes into the database? If yes, will the reference to the package work? For example, in a JDev generated class (the soap client class), it has package MyJdev.proxy; at the top. Or, will it work if I load all the classes included in package /MyJdev/proxy into the database?
    Thank you very much for any help.

    For the java stored proc called from pl/sql, the example above that uses dynamic sql should word :
    TYPE Ref_Cursor_t IS REF CURSOR;
    FUNCTION get_good_ids RETURN VARCHAR2 ;
    FUNCTION get_plsql_table_A RETURN Ref_Cursor_t;
    END MyPackage;
    NAME 'MyServer.getGoodIds() return java.lang.String';
    FUNCTION get_plsql_table_A RETURN Ref_Cursor_t
    IS table_cursor Ref_Cursor_t;
    good_ids VARCHAR2(100);
    good_ids := get_good_ids();
    OPEN table_cursor FOR 'SELECT id, name FROM TableA WHERE id IN ( ' &#0124; &#0124; good_ids &#0124; &#0124; ')';
    RETURN table_cursor;
    END MyPackage;
    public class MyServer{
    public static String getGoodIds() throws SQLException {
    return "1, 3, 6 ";

  • How to publish a Java Stored proc....

    I wrote the following Java code and loaded it into Oracle 8i, as Java stored procs.
    public class EmployeeStruct
    public int EmployeeNum;
    public String EmployeeName;
    public String Designation;
    import java.sql.*;
    import oracle.jdbc.driver.*;
    public class InsertData
    public static InsertEmployee(EmployeeStruct eps) throws SQLException
    Connection conn =
    String sql = "INSERT INTO EMPLOYEE_TABLE VALUES (?, ?, ?)";
    PreparedStatement pstmt = conn.prepareStatement(sql);
    pstmt.setInt(1, eps.EmployeeNum);
    pstmt.setString(2, eps.EmployeeName);
    pstmt.setString(3, eps.Designation);
    catch (SQLException e)
    My question is how do I publish the InsertData proc. I tried :
    NAME 'INSERTDATA(EmployeeStruct)';
    but this gives me PLS-00201, identifier EmployeeStruct must be declared.
    I wish to call the java stored proc from an external java program.
    Jeevan S

    You can't pass Java classes to Java Stored Procedures via the PL/SQL wrapper. You'll have to write your wrapper to take the int as a NUMBER and the two Strings separately as VARCHAR2s, e.g.:
    EmployeeNum IN NUMBER,
    EmployeeName IN VARCHAR2,
    Designation IN VARCHAR2
    NAME 'InsertData.InsertEmployee(int, java.lang.String, java.lang.String)';

  • Creating a java stored proc in jdev

    Does anyone have a quick ref guide to creating a java stored proc in jdev? I am missing early steps to correctly setup the project.
    Thanks in advance.

    Assuming you are using ADF BC, you can try something like the following on your Application Module:
    /* our java method to call a stored procedure to send email */
    public void sendEmail(String fromEmailAddress, String toEmailAddress,
    String subject, String body1, String body2,
    String body3, String body4, String body5) {
    Object[] parms =
    { fromEmailAddress, toEmailAddress, subject, body1, body2, body3,
    body4, body5 };
    callStoredProcedure("MSKCC.proc_send_mail(?,?,?,?,?,?,?,?)", parms);
    protected void callStoredProcedure(String stmt, Object[] bindVars) {
    PreparedStatement st = null;
    try {
    // 1. Create a JDBC PreparedStatement for
    st =
    getDBTransaction().createPreparedStatement("begin " + stmt + ";end;", 0);
    if (bindVars != null) {
    // 2. Loop over values for the bind variables passed in, if any
    for (int z = 0; z < bindVars.length; z++) {
    // 3. Set the value of each bind variable in the statement
    st.setObject(z + 1, bindVars[z]);
    // 4. Execute the statement
    } catch (SQLException e) {
    throw new JboException(e);
    } finally {
    if (st != null) {
    try {
    // 5. Close the statement
    } catch (SQLException e) {
