No line numbers in stack trace from Java Stored Procedure exception

I have a Java Stored Procedure which can generate an exception. In one database (11.1.0.6) the Java stack trace contains line numbers for my code, but not for the classes loaded by default with the JVM. In another database (same version) the Java stack trace does NOT contain line numbers for my code, but does contain them for some of the classes loaded by default with the JVM!
Neither of the schemas where I am running the the Java stored procedure has a JAVA$OPTIONS tables as described here:
http://download.oracle.com/docs/cd/B28359_01/java.111/b31225/chtwo.htm#BABIGFGA
So the Java should have been compile "-debug" by default in both schemas. I specifically set the debug option to true using:
exec dbms_java.set_compiler_option('', 'debug', 'true');
but this had no effect.
Can anyone explain this behavior or tell me how to always get line number in the Java stack trace?

Hi,
Try using java.util.logging package. Using these packages you can configure your logging information to include context down to the class name. Then each log message would be unique enough to know where it came from.

How can i solve this Exception that "How can i solve this exception that "End of stack trace from previous location where exception was thrown" in Windows phone 8.

Hi Sir/Mam,
Please give me solution for this problem.I tried this in all ways for solve this problem like i checked my all class objects cleared or not when leaving current page to come to before page.
This Exception came at After saved data in the wp8 device database,then it is coming to back page(when i navigate to another page) then that navigated page running and go to "Public Asyn Void Listmenu()" method ,in this method again retrieve the
data from database after getting this data,it shows this Exception.
Note :-This Exception came in WP8 Device only,not in Emulator.In the Emulator it is working fine.
My Exception:-

Is the flow of code to the point where exception occurs:
1) Data saved in Db
2) Navigated back
3)Navigated to another page
4) Method ListMenu() is called(as soon as navigated to page in step 3) to retrieve the saved data from db & exception occurs.
Can you paste here the definition of ListMenu(), also does the exception occurs as soon as db is accessed inside this method or else.

Executing batch file from Java stored procedure hang

Dears,
I'm using the following code to execute batch file from Java Stored procedure, which is working fine from Java IDE JDeveloper 10.1.3.4.
public static String runFile(String drive)
String result = "";
String content = "echo off\n" + "vol " + drive + ": | find /i \"Serial Number is\"";
try {
File directory = new File(drive + ":");
File file = File.createTempFile("bb1", ".bat", directory);
file.deleteOnExit();
FileWriter fw = new java.io.FileWriter(file);
fw.write(content);
fw.close();
// The next line is the command causing the problem
Process p = Runtime.getRuntime().exec("cmd.exe /c " + file.getPath());
BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line;
while ((line = input.readLine()) != null)
result += line;
input.close();
file.delete();
result = result.substring( result.lastIndexOf( ' ' )).trim();
} catch (Exception e) {
e.printStackTrace();
result = e.getClass().getName() + " : " + e.getMessage();
return result;
The above code is used in getting the volume of a drive on windows, something like "80EC-C230"
I gave the SYSTEM schema the required privilege to execute the code.
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'java.io.FilePermission', '<<ALL FILES>>', 'read ,write, execute, delete');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
EXEC DBMS_JAVA.grant_permission('SYSTEM', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
GRANT JAVAUSERPRIV TO SYSTEM;
I have used the following to load the class in Oracle 9ir2 DB:
loadjava -u [system/******@orcl|mailto:system/******@orcl] -v -resolve C:\Server\src\net\dev\Util.java
CREATE FUNCTION A1(drive IN VARCHAR2) RETURN VARCHAR2 AS LANGUAGE JAVA NAME 'net.dev.Util.a1(java.lang.String) return java.lang.String';
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
The problem that it hangs when I execute the call to the function (I have indicated the line causing the problem in a comment in the code).
I have seen similar problems on other forums, but no solution posted
[http://oracle.ittoolbox.com/groups/technical-functional/oracle-jdeveloper-l/run-an-exe-file-using-oracle-database-trigger-1567662]
I have posted this in JDeveloper forum ([t-853821]) but suggested to post for forum in DB.
Can anyne help?

Dear Peter,
You are totally right, I got this as mistake copy paste. I'm just having a Java utility for running external files outside Oracle DB, this is the method runFile()
I'm passing it the content of script and names of file to be created on the fly and executed then deleted, sorry for the mistake in creating caller function.
The main point, how I claim that the line in code where creating external process is the problem. I have tried the code with commenting this line and it was working ok, I made this to make sure of the permission required that I need to give to the schema passing security permission problems.
The function script is running perfect if I'm executing vbs script outside Oracle using something like "cscript //NoLogo aaa1.vbs", but when I use the command line the call just never returns to me "cmd.exe /c bb1.bat".
where content of bb1.bat as follows:
echo off
vol C: | find /i "Serial Number is"
The above batch file just get the serial number of hard drive assigned when windows formatted HD.
Same code runs outside Oracle just fine, but inside Oracle doesn't return if I exectued the following:
variable serial1 varchar2(1000);
call A1( 'C' ) into :serial1;
Never returns
Thanks for tracing teh issue to that details ;) hope you coul help.

How to call EJB deployed on OC4J from java stored procedure?

Hello,
I'd like to call EJB from java stored procedure. My example works fine from command line, but the problem seems to be with deployment of this code into database. Especialy I'm wondering how to reference jars like oc4jclient.jar, ejb.jar, ... from java stored procedure.

Return national language strings from java stored procedures

Hi, all.
How does i can return String which contains national characters from java stored procedure? I.e. convert UTF java string to national language of database. It's does not processing automatically (why?).

OS: Windows 2000 Server
Oracle Server version: Oracle 8.1.7.1.4

Ok. I had a specific problem.
I want to use java stored procedure (function) to make a connection to remote db using supplied connection parameters make some quieries there end return results in a form of structured data - object.
I have defined an object type in a database where the function will reside. I granted execute privilege to public user on this type, made public synonyms to both, the object type and the function, so anybody connected to the same database would have an access to this functionality.
I supposed that if I supply connection parameters for some other user but the same database when running the function, everything should go smooth. Yeah.
My java code executed ok: it made a connection to the db with some x user, it resolved object type descriptor given (oracle.sql.StructDescriptor), but pl/sql wrapper function reported the error I've mentioned. If I executed the function giving it the connection parameters for same account as where object type was declared, everything went fine.
My final solution is:
Make TWO! connection in java code: 1st for ("jdbc:default:connection:"), 2nd for remote database account.
Use first connection to construct oracle.sql.StructDescriptor
Use second connection to retreive data from remote db

ResultSet from Java Stored Procedures

Hi,
How do I obtain a resultset from a Java Stored Procedure?
My stored procedure, deployed in Oracle8i, has Database package as sample.Have published setConnection() and getDept() methods.
Code for Java Stored Procedure:
package SPPackage;
import java.sql.*;
public class StoredProcApplication {
protected static Connection connection = null;
protected static Statement stmt = null;
protected static ResultSet res = null;
public static void setConnection() throws SQLException {
connection = new oracle.jdbc.driver.OracleDriver().defaultConnection();
public static void getDept(Object[] obj) throws SQLException {
if (connection == null) {
setConnection();
if (stmt == null) {
stmt = connection.createStatement();
if (res == null) {
res = stmt.executeQuery("select * from DEPT");
obj[0] = res;
Code for TesterApplication :
package SPPackage;
import java.sql.*;
public class TesterApplication {
private static final String URL = "jdbc:oracle:thin:@sandeep:1521:oracle8i";
private static final String userId = "sandeep";
private static final String password = "sandeep";
private Connection connection;
private CallableStatement stmt;
private ResultSet res;
public void setConnection() throws ClassNotFoundException,SQLException {
Class.forName("oracle.jdbc.driver.OracleDriver");
connection = DriverManager.getConnection(URL,userId,password);
public void getResultFromSP() throws SQLException {
//prepare to call the stored procedure
stmt = connection.prepareCall("{call sample.getDept(?)}");
//register the OUT parameters
stmt.registerOutParameter(1,Types.OTHER);
//execute the query
stmt.execute();
ResultSet res = (ResultSet)stmt.getObject(1);
while (res.next()) {
System.out.print(res.getInt(1) + " | " );
System.out.print(res.getString(2) + " | " );
System.out.print(res.getString(3) + " \n " );
public TesterApplication() throws SQLException,ClassNotFoundException {
try {
setConnection();
getResultFromSP();
} finally {
if (res != null) { res.close(); res = null; }
if (stmt != null) { stmt.close(); stmt = null; }
if (connection != null) { connection.close(); connection = null; }
public static void main(String[] args) {
try {
TesterApplication ta = new TesterApplication();
} catch (Exception e) {
System.err.println("Error while executing stored procedure " + e.getMessage());
e.printStackTrace();
When I run the TesterApplication, I get the following exception :
java.sql.SQLException: Invalid column type: get_internal_type
at oracle.jdbc.dbaccess.DBError.check_error(Compiled Code)
at oracle.jdbc.driver.OracleStatement.get_internal_type(Compiled Code)
at oracle.jdbc.driver.OracleCallableStatement.registerOutParameter(Compiled Code)
Also, if I want to execute the ResultSet in the stored proc itself, and return the values as Arrays of int[], and String[], how do I do it?By default the you can populate only int[0], String[0] , i.e. only one value!!!
if my statement is unknown, i.e, it might return a combination of updates and resultsets, how do I go about processing the result?
Please advise!!
TIA

Hi kkirk,
I found the post you mentioned.Well it dates back to November 1999 - "Problem returning resultset or ARRAY from java stored proc" by Stuart Popejoy ([email protected]).Too bad, it is still not solved!!
I am not very good at PL/SQL.However, it would still be helpful, if you could post the code here, or at my email address.
Meanwhile, I was trying this during the week-end.There seems to be a glimmer of hope!!
Let me know, if this makes sense :
CallableStatement cs = connection.prepareCall("begin open ? for select * from dept; end");
try {
cs.registerOutParameter(1,OracleTypes.CURSOR);
ResultSet res = ((OracleCallableStatement)cs).getCursor(1);
while (res.next()) {
//get the values
} catch (Exception e) {
e.printStacktrace();
However, I am getting an exception trace
Error while executing stored procedure Invalid column type: getLong
java.sql.SQLException: Invalid column type: getLong

Not quite sure why this is happening!!

Invoking a UNIX shell command from Java stored procedure

The program below is suppose do send an email using UNIX mailx program. It works correctly when I compile it in UNIX and invoke it from the command line by sending an email to the given address.
I need this program to run as a stored procedure, however. I deploy it as such and try to invoke it. It prints the results correctly to the standard output. It does not send any emails, however. One other difference in execution is that when invoked from the command line, the program takes about a minute to return. When invoked as a stored procedure in PL/SQL program or SQL*Plus anonymous block, it returns immediately.
Why would mailx invocation not work from a stored procedure? Are there other ways to invoke mailx from PL/SQL?
Thank you.

import java.io.BufferedWriter;

public static void main(String[] args)
System.out.println(mailx("Hey, there", "Hello", "oracle@solaris10ora", 1));

* @param subject message subject
* @param addressee message addressee
* @param display if greater than 0, display the command
* @return OS process return code
public static int mailx(String message, String subject,
String addressee, int display)
System.out.println("In mailx()");
try
String command =
"echo \"" + message + "\" | mailx -r [email protected]" + " -s \"" + subject + "\" " + addressee;
if (display > 0)
System.out.println(command);
try
Process process = Runtime.getRuntime().exec("/bin/bash");
BufferedWriter outCommand =
new BufferedWriter(new OutputStreamWriter(process.getOutputStream()));
outCommand.write(command, 0, command.length());
outCommand.newLine();
outCommand.write("exit", 0, 4);
outCommand.newLine();
outCommand.flush();
process.waitFor();
outCommand.close();
return process.exitValue();
catch (IOException e)
e.printStackTrace();
return -1;
catch (Exception e)
e.printStackTrace();
return -1;

try adding the full explicit path to "mailx" in the command string that gets sent to Runtime. i would guess that the shell that gets spawned might not have a proper environment and thus mailx might not be found.

How to execute a procedure or function from Java Stored procedure

Hi,
I am new to Java Stored Procedures. I am working on Oracle 8i and JVM 1.3.1. I want to call a PL/SQL procedure from within Java. I have tried looking at severa; cources but they are quite high level for me. Can someone provide a simple example including the Source Code for .java file and also the calling function's code?
Heres a sample of what I have been working on: I an including Java code, and Function code and how I call the function. Instead of doing "select sysdate from dual" I want to do like "create table temp1(var1 varchar2(10))" or similar... like "exec procname(var1)" etc.
Thanks in advance.
PS. The variable passed in function is just a dummy variable.

Calling XML API's from Java Stored Procedures in DB

Hi,
I am have and Oracle 10gR2 db installed and XML Publisher Enterprise Server 5.6.2.
I have created the following Java Class and used loadjava to make it a Java Stored Procedure:
<code>
import java.io.IOException;
import java.lang.Object;
import oracle.apps.xdo.XDOException;
import oracle.apps.xdo.template.FOProcessor;
import oracle.apps.xdo.template.RTFProcessor;
public class callingXMLP{
public static String rtfToXsl(String rtfFile, String xslFile)
try {
RTFProcessor rtfProcessor = new RTFProcessor(rtfFile); //Input RTF
rtfProcessor.setOutput(xslFile);
rtfProcessor.process();
} catch (IOException IOE) {
return" Error "+IOE.getMessage();}
catch(XDOException XDE ){
return" Error "+XDE.getMessage();
return "Success";
public static String mergeXmlXsl(String xmlFile, String xslFile, String outputFile)
FOProcessor processor = new FOProcessor();
processor.setData(xmlFile); //Input XML File
processor.setTemplate(xslFile); //Input XSL File
processor.setOutput(outputFile); //Ouput File
processor.setOutputFormat(FOProcessor.FORMAT_PDF);
//start processing
try {
processor.generate();
catch (XDOException e){
e.printStackTrace();
//System.exit(1);
return "Error - "+e.getMessage();
//System.exit(0);
return "Success";
</code>
I then wrap this using the following function spec in pl/sql:
create or replace function callXMLP(input1 VARCHAR2, output1 VARCHAR2) RETURN VARCHAR2
as language java name 'callingXMLP.rtfToXsl(java.lang.String,java.lang.String) return java.lang.String';
and
create or replace function mergeXMLXSL(xml VARCHAR2, xsl VARCHAR2, output VARCHAR2) RETURN VARCHAR2
as language java name 'callingXMLP.mergeXmlXsl(java.lang.String,java.lang.String,java.lang.String) return java.lang.String';
Calling the callXMLP function works fine, and produces an XSL file from the input RTF file as expected.
When I run the mergeXMLXSL function, it says that the function has completed successfully, but it seems to be throwing an XDOException error as it is returning "Error - null" message from the Java.
A PDF document is being created, but it does not have any content. I have also modified the Java to create an RTF instead, but still the same thing happens.
Is there anything that I need to check, or something that I am missing when trying to create the final PDF document?
Please help, I am completely stuck with this now.
Many Thanks,
Cj

Remote execution of DTS packages from Java Stored Procedures

I'm an Oracle 10G DBA and Linux/Unix Sysadmin looking for a Java guru to help me find a reusable template or locate a solid programming methodology (examples) that will enable me to connect via JDSI to SQL Server 2000/2005 and remotely execute DTS packages from within Oracle. I am working at office that's absolutely addicted to MicroSlop products and the DBA team cannot conceive of giving up their precious DTS packages. I've already converted their MS SQL Server 2000 database to Oracle 10G on RHEL4 via SQLDeveloper but I am unschooled in the art of java programming and would like to locate some sort of rudimentary template or examples or java class that can easily be loaded into the Oracle 10G database instance via the loadjava utility. These java classes/methods/stored procedures need to be executable from within embedded PL/SQL code and able to connect to SQL Server 2000 to execute DTS packages via passing dtsrun commands ... Any help or direction would be greatly appreciated.

Hi Ilford:
Sure you can use fully package notation in your Java classes.
Look at this Java source code:
http://dbprism.cvs.sourceforge.net/dbprism/cms-2.1/src/com/prism/cms/core/
All of them are Java Stored procedures.
Best regards, Marcelo.

Jena Adapter API access from Java Stored Procedures?

Is it possible to use Jena API from code in java stored procedures in Oracle DBMS 11gR2? Possible but not recommended?
The reason is that my company uses .Net as the application server plattform (not Java). Calling Java Stored Procedures from .Net is one way to use Jena library.
Thank you!
Trond

Hi Trond,
Unfortunately the sdordfclient.jar was compiled and built with JDK 6 and the JVM supported in the Oracle database 11gR2 is JDK5.
If you have a strong requirement, please file a SR against Oracle support. We will then look into a possible recompilation and
rebuild.
Thanks,

Passing Tables back from Java Stored Procedures

Thomas Kyte has written (in reference to
trying to pass an array back from a stored
function call):
You can do one of two things (and both require the use of
objects). You cannot use PLSQL table types as JDBC cannot bind to
this type -- we must use OBJECT Types.
[snip]
Another way is to use a result set and "select * from
plsql_function". It could look like this:
ops$tkyte@8i> create or replace type myTableType as table of
varchar2 (64);
2 /
Type created.
ops$tkyte@8i>
ops$tkyte@8i>
ops$tkyte@8i> create or replace
2 function demo_proc2( p_rows_to_make_up in number )
3 return myTableType
4 as
5 l_data myTableType := myTableType();
6 begin
7 for i in 1 .. p_rows_to_make_up
8 loop
9 l_data.extend;
10 l_data(i) := 'Made up row ' | | i;
11 end loop;
12 return l_data;
13 end;
14 /
Function created.
ops$tkyte@8i>
ops$tkyte@8i> select *
2 from the ( select cast( demo_proc2(5) as mytableType )
3 from dual );
COLUMN_VALUE
Made up row 1
Made up row 2
Made up row 3
Made up row 4 [Image]
Made up row 5
So, your JDBC program would just run the query to get the data.
If the function "demo_proc2" cannot be called from SQL for
whatever reason (eg: it calls an impure function in another piece
of code or it itself tries to modify the database via an insert
or whatever), you'll just make a package like:
ops$tkyte@8i> create or replace package my_pkg
2 as
3
4 procedure Make_up_the_data( p_rows_to_make_up in
number ); 5 function Get_The_Data return myTableType;
6 end;
7 /
Package created.
ops$tkyte@8i>
ops$tkyte@8i> create or replace package body my_pkg
2 as
3
4 g_data myTableType;
5
6 procedure Make_up_the_data( p_rows_to_make_up in number )
7 as
8 begin
9 g_data := myTableType();
10 for i in 1 .. p_rows_to_make_up
11 loop
12 g_data.extend;
13 g_data(i) := 'Made up row ' | | i;
14 end loop;
15 end;
16
17
18 function get_the_data return myTableType
19 is
20 begin
21 return g_data;
22 end;
23
24 end;
25 /
Package body created.
ops$tkyte@8i>
ops$tkyte@8i> exec my_pkg.make_up_the_data( 3 );
PL/SQL procedure successfully completed.
ops$tkyte@8i>
ops$tkyte@8i> select *
2 from the ( select cast( my_pkg.get_the_data as mytableType
) 3 from dual );
COLUMN_VALUE
Made up row 1
Made up row 2
Made up row 3
And you'll call the procedure followed by a query to get the
data...
I have tried this, and it works perfectly.
My question, is what does the wrapper look
like if the stored function is written
in java instead of PL/SQL? My experiments
with putting the function in java have been
dismal failures. (I supposed I should also
ask how the java stored procedure might
look also, as I suppose that could be where
I have been having a problem)

Thanks for the response Avi, but I think I need to clarify my question. The articles referenced in your link tended to describe using PL/SQL ref cursors in Java stored procedures and also the desire to pass ref cursors from Java to PL/SQL programs. Unfortunately, what I am looking to do is the opposite.
We currently have several Java stored procedures that are accessed via select statements that have become a performance bottleneck in our system. Originally the business requirements were such that only a small number of rows were ever selected and passed into the Java stored procedures. Well, business requirements have changed and now thousands and potentially tens of thousands of rows can be passed in. We benchmarked Java stored procedures vs. PL/SQL stored procedures being accessed via a select statement and PL/SQL had far better performance and scaleable. So, our thought is by decouple the persistence logic into PL/SQL and keeping the business logic in Java stored procedures we can increase performance without having to do a major rewrite of the existing code. This leads to the current problem.
What we currently do is select into a Java stored procedure which has many database access calls. What we would like to do is select against a PL/SQL stored procedure to aggregate the data and then pass that data via a ref cursor (or whatever structure is acceptable) to a Java stored procedure. This would save us a significant amount of work since the current Java stored procedures would simple need to be changed to not make database calls since the data would be handed to them.
Is there a way to send a ref cursor from PL/SQL as an input parameter to a Java stored procedure? My call would potentially look like this:
SELECT java_stored_proc(pl/sql_stored_proc(col_id))
FROM table_of_5000_rows;
Sorry for the lengthy post.

Accessing files from Java Stored Procedures

I am trying to access a file from a Java Stored Procedure but get the exception: "no such file or directory". The path and filename as seen by the database JVM is "\\wgcaub01\a1500is\fabi\mmv\mmvtestdata.txt".
I have granted permissions to open the file using:
call dbms_java.grant_permission('MMV', 'java.io.FilePermission', '\\\\wgcaub01\\a1500is\\fabi\\mmv\\mmvtestdata.txt', 'read');
a) When I run the program as a Java class using a main method it works so the problem has to do with the Oracle JVM not finding the file.
b) The MMV user has permissions on the file after granting them using the above dbms_java.grant_permission command.
Can you tell me what am I missing? Is this a database configuration issue? Is there a problem with using a UNC path?
(I am using FileReader and BufferedReader.)

Vincent,
Not sure if this is the cause of your problem, but I had some Java code which read from/wrote to a file, and I needed to run the following (you can obviously change <<ALL FILES>> to something more restrictive):
declare
security_key number;
begin
dbms_java.grant_permission('DAN', 'java.io.FilePermission', '<<ALL FILES>>', 'read,write,execute,delete', security_key);
dbms_java.grant_permission('DAN', 'java.lang.RuntimePermission', 'writeFileDescriptor', NULL, security_key);
dbms_java.grant_permission('DAN', 'java.lang.RuntimePermission', 'readFileDescriptor', NULL, security_key);
end;
Note that the security_key won't be set if the grant didn't work.
Hope this helps,
-Dan
