How to debug noclassdeferror from java stored procedure.

Hi,
I am making use of OracleSoapHttpConnection class to call a webservice from a java stored procedure. I used loadjava to load the soap.jar, everything loaded without any error. We can see the "OracleSoapHTTPConnection" class loaded in the all_objects table, still during runtime we get noclassdeferror. I am not sure on how to set classpath for oracle database jvm.
Many Thanks.
Chandana

Please don't post duplicate messages in the forum. You're just cluttering up the place. How to resolve a noclassdeferror for OracleSoapHttpConnection class

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.
Is there some example how to do that ?
Can You help me please ?
Many thanks,

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.

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?).
declaration of procedure:
CREATE OR REPLACE FUNCTION TestNLSString RETURN VARCHAR2
AS
LANGUAGE JAVA
NAME 'test.SomeClass.getNLSString() return java.lang.String';
SELECT TestNLSString AS X FROM DUAL;
X

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

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.

How to get connection of the db lite from java stored procedure?

Hello! All.,
I have a written java stored procedures to assign sequence keys, and update some tables. The procedure is working as per our need by using the following connection information.
try {
int rowFetched = 0;
Class.forName("oracle.lite.poljdbc.POLJDBCDriver");
// connect to the database
Connection conn = DriverManager.getConnection("jdbc:polite:polite",
"system", "manager");
My question is, It is possible in db lite to get a default connections like we use in the enterprise database
conn = new OracleDriver().defaultConnection();
Could anybody please shed some light on this.
Thanks in advance.

Hello Upi! out of curiosity if you happen to know the answer for the following, I do appreciate it.
Hello! We are using BC/ADF JClient to select and for any DML operation against Oracle Lite database. We may have more than one user(s) log on to our application, so we requires to authenticate oracle lite user credential using JDBC dynamically.
I am utilizing the features of JCLoginDialog.java and manipulation bc4j.xcfg file. This work real good for accepting username/password credentials dynamically, since we have multiple database in one computer I have to accept DSN name and if possible built my own configuration file.

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.

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
at oracle.jdbc.dbaccess.DBError.check_error(Compiled Code)
at oracle.jdbc.driver.OracleStatement.getLongValue(Compiled Code)
Not quite sure why this is happening!!

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)
null

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

Using JNDI from Java Stored Procedures

Hi,
we want to call external services (mostly via middle tier/J2EE) from within the database (9i Rel. 2) using Java Stored Procedures and JNDI.
Does anybody have some hints/samples how to do this? Will we have to use oc4jclient.jar? If yes, how? Where can I find some more detailed documentation?
Lot's of questions...
Thank
Matthias

Uh, not JNI but JNDI you asked. And use of JNI should be generally discouraged unless there is absolutely no other way (like co-located CORBA code for decoupling+speed). Can you direct me to a HOW-TO Oracle DB JVM configuration page? I want to know how to configure the internal DB JVM in a hurry.
Thank you,

Updating tables from Java Stored Procedures

"Oracle8i Tips & Techniques" says that Java Stored Procedures "should not modify any database tables" when called from Data Manipulation Language (DML) SQL (e.g. selects).
I have a need to do this.
Does any one know if I can call my Java from a PL/SQL stored procedure which is called from the DML SQL (e.g. via a function). That is to say java called from PL/SQL called from DML-SQL, or is this just hopeful thinking.
Any other Ideas?
Thanks in advance

How may one increase JVM/Java Stored Procedure Perfomance?

Hi all,
my question: How can one increase the performance of the Oracle JVM, especially of Java Stored Procedures?
I ask this because I did some performance analysis (and was horrified :):
I have a static Java method that'll need an average 15 ms to return - when executed locally.
The same code, uploaded to an Oracle10g instance and published as Java Stored Procedure will take awful *925 ms*.
I measured both times from within the method as shown below:
public class JSProc {
public static void doSomething() {
long start = System.currentTimeMillis();
// now comes the '15 ms'-code
long time = System.currentTimeMillis() - start;
That way, I'm not including any call spec overhead, network communication or whatever into the 925 ms. All in all the above procedure call will take about 1200 to 1500 ms until it returns to the client...
The hardware: both client/server computers have the same hardware, both use the JDK provided with the latest Oracle10g release; single difference: client is Win2K, server is Linux.
I would be immensely grateful for your suggestions concerning the possibilities to increase the JVM performance...
Greetings,
Sam

As Avi suggested, subsequent calls of the procedure within the same session will reduce the execution time down to 40 ms in my testing environment.
But that doesn't change anything for the 'first call' - when I start a new client program that opens a new connection, the Java Stored Proc will again need about a second to return.
I wrote the procedure now in PL/SQL - it will return in less than 30 ms, subsequent calls will return in less than a ms. Guess what I'll use :)
I played around with the JAVA* configuration params, but, as expected, that doesn't change anything in terms of performance. According to documentation, it will only affect the amount of classes I can load into the server.
I just read that Oracle creates a new "little" JVM for every session, and I imagine that there's lot of method intercepting and things (the ominous AOP-code) to ensure transaction security.
That's why I come to the conclusion that I won't use Java Stored Procedures for classical "connect, execute, disconnect" client-server applications. It's like full braking on the freeway :)

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
