Java Stored Proc. and Linux User

Hi
When Oracle run some Java class inside Oracle9i DB what Linux user it use to run them? Is it user named oracle?

If the Java class only runs inside Oracle, it will run with whatever Oracle permissions the caller has. If the Java class interacts with the system outside of Oracle (i.e. reading and writing files), it will run as whatever user Oracle runs as (i.e. generally oracle).

  • Java Stored Proc and Oracle 8.0.6.20?

    Hi,
    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, passing BLOB, not stored in a table.

    I have checked this article, and found it will not suit my needs.
    http://otn.oracle.com/sample_code/tech/java/codesnippet/jdbc/lob/LobToSP.html
    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 ?
    D

    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.

  • Can't execute OS-level command from java stored proc

    I've written a couple simple java stored procs, the first of which writes an file and the second attempts a chown on it. I can write the file (which is written as the oracle user) just fine. I need to chown it, but can't. Here's the first proc:
    public static String writefile()
    String fileName = "/joetest/test.xml";
    try {
    File f = new File(fileName);
    FileOutputStream out = new FileOutputStream(f);
    PrintStream p = new PrintStream(out);
    p.println("this is only a test");
    p.close();
    return "create file successful!!!";
    } catch (Exception e) {
    return "Exception occurred writing file:"+e;
    Here's the proc I've been stuggling with:
    public static String chown(String inString)
    String[] command = {"/bin/sh", "-c", "/usr/bin/chown notjoe /joetest/test.xml"};
    if (inString != null) {
    command[2] = inString;
    try {
    Process p = Runtime.getRuntime().exec(command);
    return "Ownership change success!! "+p;
    } catch (Exception e) {
    return "Ownership change failure?? err="+e;
    The package is created with:
    CREATE OR REPLACE PACKAGE JOE.THISISATEST AS
    FUNCTION writefile
    return VARCHAR2
    AS
    LANGUAGE java
    NAME 'thisisatest.writefile() return java.lang.String';
    FUNCTION chown(Param1 VARCHAR2)
    return VARCHAR2
    AS
    LANGUAGE java
    NAME 'thisisatest.chown(java.lang.String) return java.lang.String';
    end;
    And I've granted the following privileges:
    begin
    dbms_java.grant_permission('JOE', 'java.io.FilePermission', '/joetest/test.xml', 'read, write, execute, delete');
    end;
    begin
    dbms_java.grant_permission('JOE', 'java.io.FilePermission', '/usr/bin/chown', 'execute');
    end;
    begin
    dbms_java.grant_permission('JOE', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
    end;
    begin
    dbms_java.grant_permission('JOE', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
    end;
    Here's the error that I'm getting:
    ORA-06502: PL/SQL: numeric or value error: character string buffer too small
    Coincidentally, this is the same error that I used to get when I wrote the file without having been granted write privileges. Once I granted myself the proper 'write' permissions I could perform file IO just fine. Is there some runtime permission that I need to grant myself to run chown? I'm just guessing, as I can't find any permission like that in the java documentation. I have 'execute' permission on /usr/bin/chown and the oracle user can execute the command I'm attempting from the command line. ARRRRRGH.
    I am at my wits end with this. I've tried what seems like a thousand different syntaxes for the OS command and ran it from many different directories. Anyone have any thoughts at all as to why this is happening? I'm just clutching at straws now...

    Hmmmm. Granting 'execute' on '<<ALL FILES>>' to user JOE fixes this problem:
    begin
    dbms_java.grant_permission('JOE', 'java.io.FilePermission', '<<ALL FILES>>', 'execute');
    end;
    My security folks will not allow this when I port to production, but at least it is something.

    exec dbms_java.set_output(1000000)Hope this helps.

  • 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 java.io.IOException;
    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 =
    DocumentBuilderFactory.newInstance();
    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 9.2.0.6, 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 9.2.0.6 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?
    Thanks,

  • 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 java.io.IOException;
    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 =
    DocumentBuilderFactory.newInstance();
    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.
    thanks
    Dale

    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 status

    hello.
    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)?
    E.g.
    - 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
    VALID to INVALID?
    Thanks.
    Min

    Min:
    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.

    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.:
    CREATE OR REPLACE PROCEDURE insert_data
    EmployeeNum IN NUMBER,
    EmployeeName IN VARCHAR2,
    Designation IN VARCHAR2
    AS LANGUAGE JAVA

    2. Execute a command to open notepad screen.
    3. Open a new Frame and display it.
    These three are simple testing, Item 1 works fine, however,
    Item 2 and 3 never works.
    IS JAVA STORED PROC CAN ONLY DO SQL TYPES OF WORK (INSERT, DELETE, UPDATE) ?
    The errors I have for Items 2 and 3 are like:
    1. When loading java: Java call terminated by uncaught Java exception:
    oracle.aurora.awt.UnsupportedOperation:GUI not supported.
    2. When triger is fired: class SCOTT.DBTrigger could not be resolved.
    Thanks for help !!

    As far as I know java stored procedures can't use any GUI classes. Only unvisible actions!

  • Calling an EJB deployed in OC4J from Java Stored Proc in Oracle

    Hello!
    Trying to make a call to an EJB deployed in OCJ4 from a oracle java stored proc. After loaded orion.jar and crimson.jar lib into SCOTT schema, I can't get the JNDI Context working because of this error:
    ============================================
    javax.naming.NoInitialContextException: Cannot instantiate class:
    com.evermind.server.ApplicationClientInitialContextFactory. Root exception is
    java.lang.ClassNotFoundException:
    com/evermind/server/ApplicationClientInitialContextFactory
    at java.lang.Class.forName0(Class.java)

    at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java)
    at javax.naming.InitialContext.init(InitialContext.java)
    at javax.naming.InitialContext.<init>(InitialContext.java)
    ===============================
    I did load the java with "loadjava" with on time with the "resolve" option and time time no option and still no working.
    Here is the EJB client code:
    =======================================
    import java.sql.*;
    import java.util.*;
    import javax.naming.*;
    import com.evermind.server.ApplicationClientInitialContextFactory;
    class EmpRemoteCall {
    public static void main(String[] args) {
    System.out.println(getEmpName());
    public static String getEmpName() {
    String ejbUrl = "java:comp/env/ejb/Emp";
    String username = "admin";
    String password = "admin";
    Hashtable environment = new Hashtable();
    environment.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.ApplicationClientInitialContextFactory");
    environment.put(Context.PROVIDER_URL, "ormi://127.0.0.1/testemp");
    environment.put(Context.SECURITY_PRINCIPAL, username);
    environment.put(Context.SECURITY_CREDENTIALS, password);
    //environment.put(Context.SECURITY_AUTHENTICATION, ServiceCtx.NON_SSL_LOGIN);
    //environment.put(javax.naming.Context.URL_PKG_PREFIXES, "oracle.aurora.jndi");
    com.kboum.sertir.essais.EmpHome homeInterface = null;
    try {
    Class.forName("com.evermind.server.ApplicationClientInitialContextFactory", true, ClassLoader.getSystemClassLoader());
    System.out.println("Creating an initial context");
    Context ic = new InitialContext(environment);
    System.out.println("Looking for the EJB published as 'java:comp/env/ejb/Emp'");
    homeInterface = (com.kboum.sertir.essais.EmpHome) ic.lookup(ejbUrl);
    catch (CommunicationException e) {
    System.out.println("Unable to connect: " + ejbUrl);
    e.printStackTrace();
    //System.exit(1);
    catch (NamingException e) {
    System.out.println("Exception occurred!");
    System.out.println("Cause: This may be an unknown URL, or some" +
    " classes required by the EJB are missing from your classpath.");
    System.out.println("Suggestion: Check the components of the URL," +
    " and make sure your project includes a library containing the" +
    " EJB .jar files generated by the deployment utility.");
    e.printStackTrace();
    //System.exit(1);
    catch (ClassNotFoundException e) {
    System.out.println("Unable to connect: " + ejbUrl);
    e.printStackTrace();
    //System.exit(1);
    try {
    System.out.println("Creating a new EJB instance");
    com.kboum.sertir.essais.Emp remoteInterface = homeInterface.findByPrimaryKey(Integer.valueOf("7369"));
    System.out.println(remoteInterface.getENAME());
    System.out.println(remoteInterface.getSAL());
    remoteInterface.setSAL(2);
    System.out.println(remoteInterface.getSAL());
    return remoteInterface.getENAME();
    catch (Exception e) {
    System.out.println(e.getMessage());
    e.printStackTrace();
    return "error";
    null

    What I did to solve this problem was to
    create a simple RMI remote object that
    resides outside the database JVM and that
    serves as a proxy EJB client for your java
    stored procedure. The stored procedure can
    invoke a method on the remote RMI object
    which then looks up the EJBean's home
    interface and invokes the relevant method on
    the bean's remote interface, and relays any
    return values back to the java stored
    procedure.
    Hope this helps,
    Avi.
