JDeveloper, Java & XML :: Java Stored Procedure Invoking Windows Run Time Process
May 22, 2012
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 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?
I have a requirement to extract data from an XML formatted string that is passed as an IN parameter to a database stored procedure. I do not have a table to store the XML, nor an XML schema, nor a namespace, just the XML string. While new to XML, I do understand the basics. Using XMLTable I am able to parse out the simplest of XML data. My problem is this; attempting to extract data from nested XML nodes results in the error
Testing a solution example I found on this site by Barbara Boehmer, I still get the ORA-19279 error. I suspect it may be because I have version 10g while she has version 11g. Her solutions is from #msg_514154. Here is that code that gives me the error:
SCOTT@orcl_11gR2> SELECT x."deptno" 2 FROM (SELECT '<departments><deptno>1</deptno><deptno>2</deptno></departments>' col FROM dual) xml_data, 3 XMLTABLE 4 ('/departments/deptno' 5 PASSING XMLTYPE (xml_data.col) 6 COLUMNS 7 "deptno" number path '/deptno') x 8 /
deptno ---------- 1 2
2 rows selected.
As I said, this example generates the ORA-19279 error. Need processing XML data from an IN parameter?
When I try to extract the date tag value from XML data, the time stored in 20120602153021 format i.e., YYYYMMDD24HHMISS format. The following statement extracts only date as 02-JUN-12 however do not extract the time part.
If I try the same in SQLplus with to_date it works however fails in PL/SQL.
XML data: <?xml version="1.0"?> <RECORD> <REGTIMESTAMP>20120601130010</REGTIMESTAMP> </RECORD>
PL/SQL Extract:
CURSOR c_xml_record IS SELECT extract(value(d), '//ACTIVATIONTS/text()').getStringVal() AS REGTIMESTAMP, FROM t_xml_data x, [code].......
I've this java source create or replace and compile java source named "Decodificador" as public class Decodificador { public static String decodifica(String codigo) return codigo;
and this function
create or replace function F_Decodificador(codigo varchar2) RETURN VARCHAR2 IS LANGUAGE java NAME 'Decodificador.decodifica(String) return String';
when I execute the function the result is:
ORA-29531: no method decodifica in class Decodificador
I need to call DB function through Java Hibernate.
My Sample XML File looks like. --------------------------------------------------------------- <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <sql-query name="getchequeno" callable="true"> ?:=call cz_nab_mw_fn_gen_ol_chq_no() </sql-query> </hibernate-mapping> --------------------------------------------------------------- I am getting below error while reading the file
"java.lang.RuntimeException: org.hibernate.HibernateException: Errors in named queries: getchequeno"
i`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
In my application, we are getting the following exception on calling the Java procedure.
java.sql.SQLException: ORA-29532: Java call terminated by uncaught Java exception: java.lang.OutOfMemoryError ORA-04030: out of process memory when trying to allocate 10804020 bytes (joxp heap,f:OldSpace)
if there is any package provided with DB that would allow me to import XML file and then use XPath to read the data? I need to insert it in proper tables then. I could see packages to create XML files, but I could not see any one to load it from the file. I could see it could be done in Java using XMLDOM, but is there any way of doing this using pure PL/SQL?
I am using an oracle 11g database. I have an XML document named test_table.xml stored in table TEST_CLOB, Ex: TEST_CLOB(ID NUMBER, XML_DOC CLOB)
Here are the contents of test_table.xml file.
<xml version = "1.0"" ?> <! DOCTYPE main [ <! Element main (DATA_RECORD*) > <! COLUMN1?, COLUMN2?, COLUMN3, COLUMN4?, COLUMN5, COLUMN6?, GEOM?) +> <! ELEEMENT COLUMN1 (#PCDATA)> <! ELEEMENT COLUMN2 (#PCDATA)>
[code]....
I need a database procedure where I will pass in COLUMN1, COLUMN2 AND COLUMN3 values and it should return all the columns from the xml document. ie. ex: below is what I would like to query
select column1, column2, column3 column4 column5, column 6 from the TEST_TABLE.XML ---- XML DOCUMENT FILE NAME WHERE column1 = 'ARENAS' AND column2 = 'NBA' AND column 3 = 'UNITED CENTER';
In my pl/sql procedure I'm calling a webservice and it is returning me a varchar2 which contains xml tags.I want to pull values for each element. any one can provide me procedure/function to pull data from it.Below is the output from webservice.
We have a stored procedure named proc_java_test . From this stored proc, we need to call a java class named java_test.java
This class posts messages to a queue hosted on an app server running on a separate box.
create or replace PROCEDURE PROC_JAVA_TEST ( num IN NUMBER ) AS LANGUAGE JAVA NAME 'java_test.post(int) ';
Is it mandatory to place java files in oracle_home/bin ? I tried placing the file on some other location and then calling it from stored proc. It did not work. Can we point oracle to read java file from location other than oracle_home/bin?
I need to invoke a JavaMail code from oracle server. Conditions are :
On insertion of a row in a table a TRIGGER is to be run. This trigger would invoke a java code, that shoots an email, with desired credentials and login.
The code to send email, is based on JavaMail API, and is compiled on JVM version, 1.6.
The javaMail code can be loaded in oracle server using:
loadjava -user scott@TESTDB SendMailSSL.class
Another code doscmd.class is written and loaded in oracle, that is compiled in java 1.5. It is intended to call the SendMailSSL.class
oracle PL/SQL. I have almost finished this xml parsing task but their is one problem. Actually in our table there are more than 70-80 columns & due to that only I don't want to put the hard coded column name in my procedure, because if I will do that, the unnecessary procedure size will be increase(means line of code).Here is our procedure
Create or replace procedure loadMyXML(dir_name IN varchar2, xmlfile IN varchar2) AS l_bfile BFILE; l_clob CLOB; l_parser dbms_xmlparser.Parser; l_doc dbms_xmldom.DOMDocument; l_nl1 dbms_xmldom.DOMNodeList; l_nl2 dbms_xmldom.DOMNodeList; l_n dbms_xmldom.DOMNode; node1 dbms_xmldom.DOMNode; l_colName VARCHAR2(100); [code]...
We need to get the single node with class type ="1" from this XML as given below.At any point of time, there will be only one such tag with classType="1". Its position could be anywhere inside the "GroupDetails" Tag.ie, The query should get the tag irrespective of its position inside "GroupDetails".
<info groupId="128" classType="1"/>
Is there any way using EXTRACT function with 3 parameter? I tried but with failure.
with rec AS ( select XMLTYPE( '<connection value="0"> <GroupDetails> <info groupId="100" classType="0"/> <info groupId="128" classType="1"/>
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 am using this syntax but its going in error, <?if:number(DAY_1)>=1 and number(DAY_1)<=25?><?attribute@incontext:background-color;'LightGreen'?><?end if?>
