JDeveloper, Java & XML :: Programs (JRE) Hang On Startup?
Jun 23, 2011
I'm facing a problem with the starting of java programs on my Win XP system. The startup most often takes from 5 to 60min. Only in rare cases java programs start-up normally. I've these problems with Eclipse, Nitro and ProM which are all Java-based tools.
I have used STraceNT to find the cause of my problems but I couldn't figure it out. I've attached the STraceNT log file for the execution of ProM. The program runs until the last line in the log while starting without showing up anything. After 20min suddenly the programs shows up and works as it normally does. The last line in the log where the software hangs for this long time is a call to WaitForeSingleObject. Before that it seams to allocate memory. I could see similar patterns in the executions of the other java programs, but I still can't see where the problem lies. I also tried removing the JRE and install different versions.
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'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
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?>
How to insert data from file .xml insert into the table which is only of value from the card file .xml into the corresponding fields of table "EMP", not insert CLOB data types in table "EMP".
How do I insert the data into the table "EMP" Are In oracle there functions and procedures which support file parsing .xml?
I want to create offline database. there is one custom application i designed but for that need to use internet.
some time there is internet fluctuation. so i want offline db concept to implement . In a day once inter net connect data will get upload and centralize. is it possible by using OAF or ADF..?
