How to use signed classes/Jars in Java Stored Procedure?

I am using java encryption API in my java application that I want to deploy as java stored procedure. The API is kept in the signed jar files.
The Application is running in the MS-DOS environment but not in Oracle8i.
It gives me following error.

ERROR at line 1:
ORA-29532: Java call terminated by uncaught Java exception:
java.lang.ExceptionInInitializerError
ORA-06512: at line 4
(Note: I have enabled the java output in SQL Plus editor otherwise it will give only the second part of error that starts from ERROR at line 1:)
please guide me how to solve this problem.

Salman,
If you do not get a reply on this forum, I recommend you post this question on the Oracle JVM discussion forum as well.
In addition, I would recommend checking the documentation for Oracle8i. The Oracle8i Java Developer's Guide, the Java Stored Procedures Guide, and the JDBC Developer's guide may have some information on this topic. You can get to this doc from the OTN Documentation page. Click on Oracle8i, then General Documentation, Release 2 (8.1.6), then scroll down to see the link for the Oracle8i Java Developer's documetation. All of the books mentioned above are available from that link.

Invoking "java myClass" using Runtime.Exec from a Java Stored Procedure

Hi All,
This is regarding the use of Runtime.getRunTime().exec, from a java programme (a Java Stored Procedure), to invoke another Java Class in command prompt.
I have read many threads here where people have been successuful in invoking OS calls, like any .exe file or batch file etc, from withing Java using the Runtime object.
Even i have tried a sample java programme from where i can invoke notepad.exe.
But i want to invoke another command prompt and run a java class, basically in this format:
{"cmd.exe","java myClass"}.
When i run my java programme (in command prompt), it doesnt invoke another command prompt...it just stays hanging.
When i run the java programme from my IDE, VisualCafe, it does open up a command prompt, but doesnt get the second command "java myCLass".
Infact on the title of the command prompt (the blue frame), shows the path of the java.exe of the Visual Cafe.
and anyway, it doesnt run my java class, that i have specified inside the programme.
Even if i try to run a JAR file, it still doesnt do anything.
(the JAR file other wise runs fine when i manually invoke it from the command prompt).
Well, my question is, actually i want to do this from a Java Stored Procedure inside oracle 8.1.7.
My feeling is, since the Java Stored Procedure wont be running from the command prompt (i will be actually invoking it through a Oracle trigger), it may be able to invoke the command prompt and run the java class i want. and that java class has to run with the SUn's Java, not Oracle JAva.
Does any one have any idea about it?
Has anyone ever invoked a java class or JAR file in command prompt from another Java Programme?
YOur help will be highly appreciated.
(P:S- Right now, my database is being upgraded, so i havent actually been able to create a Java Stored procedure and test it. But i have tested from a normal java programme running in command prompt and also from Visual Cafe).
Thanks in advance.

In other words, How to pass a Java Object from a Java stored procedure to a Java client ???
Hello,
I don't know to deal with a Vector object that has been generated from a stored procedure.
Should I create first in the JDBC client and pass it as argument to the procedure ?
Thanks in advance. Here is an extract ...
On the client side :
<<
Vector buffer = new Vector();
CallableStatement call =
con.prepareCall ("{call my_procedure_run (?, ?)}");
call.registerOutParameter(2, java.sql.Types.JAVA_OBJECT );
call.setString (1, "bla bla bla");
call.setObject (2, buffer);
call.execute ();
buffer = (Vector)call.getObject (2);
>On the Java stored procedure
<<
public class my_procedure
public static void Run(String input_value, Vector buffer)
// ??? Vector buffer = new Vector();
try
while ( true )
buffer.addElement(...) ;

How to open external files in a Java stored procedure?

Hi y'all,

I'm getting a file not found error. Where is Oracle looking (i.e., what directory)?

Hi Gary,
you must use a "database directory", e.g:
SQL>create directory WORKING_DIR as '/home2/common/';
SQL> select * from all_directories;
OWNER DIRECTORY_NAME
DIRECTORY_PATH
SYS WORKING_DIR
/home2/common/

How to use Bpel output as input in stored procedure

I am a SOA beginner. The scenario is to use the output from a BPEL process in a stored procedure as input and validate it against the data in the database. The data received from BPEL is compared with fields from different tables.
It is basically a business process data validation.
Will the output of BPEL be a Xml file and how it can b used in query of a procedure?
Edited by: 869091 on Jun 29, 2011 12:14 AM

The output from the BPEL process will be in XML format.
Your requirement is not clear, please state it properly what are you trying to do.

How to use equals in loop of an Stored Procedure

Hi ,
This is my Stored Procedure which is working fine (mean displaying all the Data from the Table)
Here i want to add this functionality that is i want to check if there is 'IND' in country_code , i want to throw an Exception manually .
I am struck up here : After the cursor fetches all the country_code in its loop , how can i check the whether country_code contains 'IND' or not in it ??
create or replace PROCEDURE Auto_After_Bod_Status
is
country_code VARCHAR2(40);
myException EXCEPTION ;
CURSOR PD1
IS
SELECT COUNTRY_CODE FROM LINK_STATUS;
BEGIN
OPEN PD1;
LOOP
FETCH PD1 INTO country_code;
DBMS_OUTPUT.PUT_LINE(country_code);
EXIT WHEN PD1%NOTFOUND;
END LOOP;
CLOSE PD1;
END Auto_After_Bod_Status;
please help .Thanks .

Check as soon as row is fetched. Also, your DBMS_OUTPUT.PUT_LINE(country_code); should be after EXIT WHEN PD1%NOTFOUND; not before:
create or replace PROCEDURE Auto_After_Bod_Status
is
country_code VARCHAR2(40);
myException EXCEPTION ;
CURSOR PD1
IS
SELECT COUNTRY_CODE FROM LINK_STATUS;
BEGIN
OPEN PD1;
LOOP
FETCH PD1 INTO country_code;
EXIT WHEN PD1%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(country_code);
IF country_code LIKE '%IND%'
THEN close pd1;
raise myException;
END IF;
END LOOP;
CLOSE PD1;
END Auto_After_Bod_Status;But if you want to fetch all rows first:
create or replace PROCEDURE Auto_After_Bod_Status
is
country_code VARCHAR2(40);
ind number := 0;
myException EXCEPTION ;
CURSOR PD1
IS
SELECT COUNTRY_CODE FROM LINK_STATUS;
BEGIN
OPEN PD1;
LOOP
FETCH PD1 INTO country_code;
EXIT WHEN PD1%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(country_code);
IF country_code LIKE '%IND%'
THEN ind := 1;
END IF;
END LOOP;
CLOSE PD1;
IF ind = 1
THEN raise myException;
END IF;
END Auto_After_Bod_Status;SY.

How to use lexical parameters with Sql Server Stored Procedure?

Hi,
I'm developing a BI Publisher report on a sql server database. I need to execute a stored procedure to dynamically build the query by replacing the lexical parameters with the values of varaibles of the stored procedure. With Oracle stored procedures, I have used data template and had reference the varaiable in SP by prefixing it with '&'.
It doesn't work if I try to do the same thing with SQL server. Is there anyone who has come across the similar situation? Please let me know if anyone has got any ideas...
Thanks in Advance

Java Stored Procedure SAXParser XML Schema Validation

Using Oracle XML Developers Kit 10.2.0.2.0 - Production.
Attempting to validate using XML Schema in a Java stored procedure with the code:
               if ( schemaDoc == null )
                    // Obtain default connection
                    Connection conn = new OracleDriver().defaultConnection();
                    OraclePreparedStatement stmt = (OraclePreparedStatement) conn.prepareStatement("SELECT XmlDocObj FROM XmlDoc WHERE XmlDocNbr = 2");
                    OracleResultSet rset = (OracleResultSet)stmt.executeQuery();
                    if ( rset.next() )
                         // get the XMLType
                         XMLType schemaXml = (XMLType)rset.getObject(1);
                         XSDBuilder builder = new XSDBuilder();
                         XMLSchema schemaDoc = (XMLSchema)builder.build(new InputSource(schemaXml.getInputStream()));
               if ( inst == null )
                    inst = new ValidateCoreRequest();
               ErrorHandlerImpl handler = inst.getNewErrorHandler();
SAXParser saxParser = new SAXParser();
saxParser.setXMLSchema(schemaDoc);
saxParser.setValidationMode(XMLParser.SCHEMA_VALIDATION);
saxParser.setErrorHandler(handler);
saxParser.parse(new InputSource(new StringReader(docStr)));
if( handler.validationError )
                    errorMsg[0] = handler.saxParseException.getMessage().substring(0, Math.min(199, handler.saxParseException.getMessage().length()));
Never reports validation errors in the XML. Although the XDK Programmers Guide states "...you can use
the oracle.xml.parser.schema.XSDBuilder class to build an XML schema and
then configure the parser to use it by invoking the XMLParser.setXMLSchema()
method. In this case, the XML parser automatically sets the validation mode to
SCHEMA_STRICT_VALIDATION and ignores the schemaLocation and
noNamespaceSchemaLocation attributes." No validation seems to occur. I have tried to set an xsi:noNamespaceSchemaLocation attribute on the root XML node, but this results in URL errors if the URL is not valid or schema build errors if the URL is valid, but does not point to a real location.
It appears that without a schema location attribute, no schema validation occurs. Using setXMLSchema() with a database source does not seem to cause the schema location attributes to be ignored. At least for Java stored procedures.
Does XML Schema validation work in the database for externally referenced schemas?
Thank You,
Art

Try this:
Edit your XSU installation script located on lib directory of Oracle XSU's distribution:
Find the line:
loadjava -r -v -u $USER_PASSWORD xmlparserv2.jar
Replace by:
loadjava -r -v -g public -u $USER_PASSWORD xmlparserv2.jar
And installs your Oracle XSU again.

View Java Stored Procedures

Hello,
How can I find the names of Java stored procedures
created in the database and what are the published
stored procedures?
thanks
Ranganath Samudrala

Hi,
There are two meta catalogs "okJavaObj" and "okJavaMember" that can be used to get all sorts of information for Java classes and Java methods. Some SQL commands are as follows:
To see all Java classes stored in the database, type in the following select statement:
select "Schema", "Name" from "okJavaObj" ;
or you may want to create the following view:
drop public synonym all_javaobjects;
create or replace view all_javaobjects( Schema, Name, SuperClass, Type) as
(select "Schema", "Name", "SuperClass", "Type" from "okJavaObj");
grant select on all_javaobjects to public;
create public synonym all_javaobjects for system.all_javaobjects;
commit;
You may want to create the following view to see classnames and methods
drop public synonym all_methods;
create or replace view all_methods
(schema,classname, superclass, declaringclass, method_name, type, argcount, jnisignature) as
select a."Schema", a."Name" as ClassName, a."SuperClass",
b."DeclaringClass" , b."Name" as method_name , b."Type",
b."ArgCount", b."JNISign" as jnisignature
from "okJavaObj" a, "okJavaMember" b
where a.POL_REF = b."DefinedIn";

Sending mail in a Java Stored Procedure

Question: What is the best way to have a Java Stored Procedure connect to our mailhost and send an email? I have been trying to use URL and URLConnection, but I found out URL somehow does not support the "mailto" protocol in the Java Stored Procedure. Funny enough the "mailto" protocol is definetely supported by URL when I test it in the JDK virtual machine.
Maybe this is the reason: I read in the 8i docs that the 8i Virtual Machine is only JDK1.1.6 compliant.
Unfortunately I can't find the 1.1.6 docs anywhere. So I cannot do any research on what protocals are supported in JDK1.1.6 .
Conclusion: Is it possible to send an email in a Java Stored Procedure, and how?
Thanks in advance :-) Johan

The Java mail API was a set of extension libraries for the 1.1 JDK. I have heard of folks who succeeded in loading these intot he database and then using them from within a Java stored procedure.

Java Stored Procedure calling HTTP Servlet in Weblogic

I am currently working on an e-commerce application for a brick-n-mortar electronics store. The store currently has an Oracle database that contains all of the products the store sells. The e-commerce site will have a separate Oracle database. Both database are Oracle 9i release 2 databases. The e-commerce site will be using BEA's Weblogic as its application server. I need to move data from the store db into the e-commerce db. The actual moving of the data is not the issue. The issue comes from needing to call several methods on a Stateless Session EJB, loaded on the Weblogic server, to perform backend processing. I wanted to make a JNDI call from a Java Stored Procedure but with Release 2, this option is no longer supported. The release notes (http://otn.oracle.com/tech/java/htdocs/9idb2_java.html) indicated that the JVM now supports calling out to Servlets using HTTP Client from a Java Stored Procedure.
Has anyone done this? Is there any sample code available?
Thanks for any help.

How to use the External Jars

Hi All,
I want to use the Api for java advanced imaging,
and i don't know where to place that jar and how to use the classes from that to do the related programming.
Please help.
Thanks
Mahesh.

any jar that's on your classpath you can use.
For information on how to use the classes in a specific library your best friend is the documentation about that library.
To have your editor/IDE know about a library, see the documentation for that editor/IDE.
