A Java program would call a sequence of 5 PLSQL procedures, and they all need to participates the Tranasction defined in Java.
What do I do for the transactions inside PLSQL to ensure all 5 pariticpate in the Java transaction? I suppose I just do not specify any COMMIT in the PLSQL, but that probably would not work as PLSQL would COMMIT by default after exiting the proc?
I am trying to execute an xslt (for XML transformation) using xmltype.transform function.
I can't paste XSLT code here, but below is similar what I am doing.
[URL]
I have used a reference of random() method of java.lang.Math in xslt file, and it's giving me below error.
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00607: Invalid reference: 'random'.
I doubt, it's because of "Math" class, which is not present in Oracle, how to load standard java classes.
I am trying to invoke program from my local Windows machine (exactly java executor, which is in my environment on c:javajdkinjava) using database package with Java stored procedure.
Everything is fired by SQLPLUS script, this script invokes package with Java stored procedure (jar loaded into Oracle) and that procedure is trying to invoke runtime process (syntax:
c:javajdkinjava -cp
and here ara my classes and main jar) using my local java executor. I added all permissions using dbms_java.grant_permisions (execution forced me to give permissions java.io.FilePermission to <<ALL_FILES>> for execute), moreover I added to my database user JAVASYSPRIV and JAVAUSERPRIV role. Unfortunately, beside this I am still getting error:
C:javajdkinjava not found (Note that lookup with PATH isn't done due to the oracle executable being setuid.)
I was getting java.sql.SQLException: executeBatch, Exception = 1when i tried to use executeBatch().could not understand why i am getting it.
View 1 Replies View RelatedI am writing a java stored procedure in my package. In the java procedure I want to issue a query to be fired on the user table from which I am calling the java procedure.
Some thing like following:
I am logged in to USER1 and my package is inside USER1. From this package I am calling the Java Stored Procedure. In java procedure I want to make a jdbc connection to USER2. The details of USER2(password, hostname,portno) are stored in a table called 'connection_details' and this table is in the USER1.
My problem is how can I issue the
SELECT details FROM CONNECTION_DETAILS for USER2
so that i can get the details..?
Do i need to first make jdbc connection to USER1 and then execute the above query for which i need similar details of USER1. How can i obtain the details of USER1 here.
I am thinking if I am already in USER1 then do I need to make the jdbc connection to USER1 and then execute the query?

Here is a problem. I have to pass an array e.g ('Account','Marketing',Computer' ) from java to Oracle 9i.
Would I be able to do in Oracle, if yes then how ?
we can you java code natively with Oracle. But I didn't get how to decide when to use native java in oracle and when to use pl/sql.
View 5 Replies View Relatedi`m trying to use pl/sql function to execute java class. I created 2 tables with around 100 values and java class with simple functionality. I need to create function to loop through my table1 and get with each iteration one value from table and pass that value as parameter to java class.
table1 is something like this:
ID NAME
1 name1
2 name2
3 name3
. .
. .
100 name100
table2 is empty with same columns as table1 ( table2 is for data obtained from java returns ) I created in sql+ java class.
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "myClass" AS
import java.io.*;
import java.util.*
public class myClass {
public static String fun(String strName)
[code]....
Then i wanna make a pl/sql function for:
1)For i = 1 Obtain first value from table1 (column name) and pass it throught java class then return value and save it in table2 with the same id as id from table1
2) change i=1 to i=2 and do that same
3) end if i=101

I am not good in xml extraction.
I Have got a requirement where we have to generate an xml conforming to a particular XSD.
What i will be having already in place is an XSD document.
We are thinking of making a procedure which will be recieving the set of inputs required for creating that xml.(Data content of that XML.)We would have to make the XML according to that XSD.
Everytime Parsing the XSD is not feasible.We are looking at a solution which would be easy to make the xml from xsd at runtime.These values (DATA) will be available at run time.
I want to retrieve values from a XML data stored on CLOB data type and store it in different table.
