Oracle 11g - Java Virtual Machine Could Not Find Main Class Program Will Exit
Jul 26, 2013
In my Organization I am trying to install oracle ODTwithODAC112030 but one Error showing that is java virtual machine could not find main class program will Exit.
Server Configuration Dell power Edge r510 Windows 2003 64 bit serv PAck 2 Citrix Presentation server 4.5 .
I have a Host system of windows 8, installed the Virtual Box Latest edition.The guest OS is the oracle Linux that came with the Pre-Built Developer VMs from Oracle.The VM is set to HOST ONLY network setting. Now, the thing is that i want to access the Oracle in the guest machine from my windows host machine.the guest OS shows the IP address as 192.168.56.101. I can ping the IP address from the HOST machine, but cannot connect theSQL developer to the oracle in the guest OS from the host machine. It keeps on saying the Network adapter cannot connect. do not say that install the oracle in window itself. I actually want to do the same on my macbook pro as that is my primary machine.
when I import java class from oracle forms (import java class ->> FFileChooser) appeared FFileChooser package but i don't know how use it how use OPEN_DIALOG or other function .
I am using Developer 10g R2. I have a form with two fields named input_value and output_value and a button named ok. I have a java class named Factorial which return the factorial of the input value. Now i want to use this class into pl/sql in ok button.
I need to add one validation in one form. The form is not getting run locally because of some imported java classes which was already there. From application server it works fine. When i run locally it gives ORA_JAVA.EXCEPTION_THROWN. Actually some trigger calls a procedure from this imported java class. Some path is specified in JNI.NEW_OBJECT(). That patg may not be in local system. If those files are included in our oracle home directory
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
How to Pick / Extract the java class files from the database.? We have not maintained the latest codes in the oracle application server where java class code is residing.
All the Java Classes are available only in database. So we need to pick the latest java class code from production environment. In TOAD we tried but all class objects are listing at the left side but we are unable to take the code. So how can we take the latest codes(java classes) from the Production Database as a backup.
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
Machine 1: Oracle server installed and database hosted on this Machine. Machine 2: Oracle client is installed and connect through sqlplus to database in machine 1.
The requirement is: I need to have a Java/C program in machine 2 (where client available) which needs to be called from the stored procedure in server on machine 1. The objective is calling a java/C program from Oracle stored procedure but available on 2 different machines. Is it possible,
We have a daily batch job executing a oracle-plsql function. Actually the quartz scheduler invokes a java program which makes a call to the oracle-plsql function. This oracle plsql function deletes data (which is more than 6 months) from 4 tables and then commits the transaction.
This batch job was running successfully in the test environment but started failing when new data was dumped to the tables which happened 2 weeks ago (The code is supposed to go into production this week). Earlier the number of rows in each table was not more than 0.1 million. But now it is 1 million in 3 tables and 2.4 million in the other table.
After running for 3 hours, we are getting a error in java (written in the log file) "...Connection reset; nested exception is java.sql.SQLException: Io exception: Connection reset....". When the row-counts on the tables were checked, it was clear that no record was deleted from any of the tables.
Is it possible in oracle database, for the plsql procedure/function to be automatically terminated/killed when the connection is timed out and the invoking session is no longer active?
I work as a Sys. Admin. for several RHEL 3.8 servers, most of them are clusters of 2 machines. All these servers are running Oracle 9.2.0.7 database. They are running fine on a separate filesystem. So everytime the system has to be formatted for some particular reason, there is no need to re-install the database.
I am trying to make some tests by running the same filesystem containing the oracle database in a fresh Red Hat Enterprise Linux 4.8 X86_64 Install. This task has become impossible, and I'm not quite sure why.
I installed all the compat- packages required for a fresh oracle 9 install in a RHEL4 machine, but at the time of stating the STARTUP sentence, it gives me the next error:
CMCLI ERROR: OpenCommPort: connect failed with error 2. CMCLI ERROR: OpenCommPort: connect failed with error 2. CMCLI ERROR: OpenCommPort: connect failed with error 2. CMCLI ERROR: OpenCommPort: connect failed with error 2. CMCLI ERROR: OpenCommPort: connect failed with error 2.
After this error (repeated) it says something like: Cannot start an already running database.... But if i stat a shutdown sentence, it says that the instance has not been initialized....
I don't know whether i have to re-install all the oracle software in order to make a clean install in the new kernel version or not, i tried to apply a patch, and the oracle installer recognized the installation i had.
I think it might be because the original system is configured to work as a cluster, and i'm running it on only a virtual machine.
It isn't possible to use one EC2 machine for each RAC node because EC2 can't handle the virtual IPs, but I had thought that I could use one EC2 machine to host several Linux VMs using Virtual Box (the same way that I use Virtual Box on a Windows host). But I can't get Virtual Box working on EC2. The only relevant advice I can find on this is comments to the effect that running any virtualization product with a Xen machine as host is not a good idea.
I do realize that this isn't a 100% Oracle question, but if set up a RAC on an Amazon Cloud machine,
I have database 10.2.0.3 with one procedure that calls some java class loaded in database. Unfortunately I don't have source code of that java class or whole jar that was loaded into database.I would like to download it from database and try to decompile it.
how can I download some java classes from database? Everything I know is only the name of some java class that is used in one PL/SQL procedure (CREATE OR REPLACE PROCEDURE ..... AS LANGUAGE JAVA).

In my PLSQL package ...How do I invoke this class file ?
So far I have done this ...
Declare abc ORA_JAVA.JOBJECT; xyz ORA_JAVA.JOBJECT; xxx VARCHAR2(25); value ORA_JAVA.JOBJECT; BEGIN
[code]...
I am getting an error saying the object type is wrong .... I would like to know how to assign a hardcoded value to the JOBJECT just to test before I continue.
Our system stores images on the unix filesystem. We scan full page images.
Our image specs are:
black and white: tiff, group4 compression, 300dpi. so files are about 40-80k compressed
photograpshs/gray scale: jpeg/jpeg compression 256 gray scale. Some images can be 2megs...but most of them are about 400-700k
We build a demo with forms10G/application server 1 year ago and performance was really bad. Took about 10-15 seconds to generate a report with 1 image of it...compared to about 1-2 secs using forms 6i. We just installed weblogic 11G (10.3.5) with forms 11gr2. I'm guessing performance will still be an issue but we will still be testing it.
Our users currently use nfs to access images on the unix server. So that would not changed.
- read_image from filesystem (c: unc path //server/images/.../1.jpeg)
- zoom in, zoom out (having vertical/hori scroll bars to move around...or best would be panning)
- save_image on filesystem
- fit to window/cancas
- always keeping aspect ratio
nice to have options, but not needed at this time
- save in blobs
- editing capabilities (mostly just select an area to delete, like black borders...some speckles here and there)
This code makes me unlucky while run that jsp report on web and comes up with orror no out put for the job.RegEdit REPORTS_CLASSPATH set to my oraclebarcode.jar with others jar files.
At Report builder web layout works fine [With Barcode generation] but not through Report server.
I have a main procedure in oracle which invokes many procedures inside it. These internal procedures also calls functions and procedures inside it.This continues to many levels.
For ex: Proc A call c call d end............
[code]...
This loop goes on and on . I want to find the names of all procedures invoked at run time when main api is executed. Is it possible to find all of them using toad ? Is there any tool for doing this ?
I've created a Java class in my Oracle DB that calls a Visual Basic program to convert a XLS file into a CSV file in order to load it into an external table. The problem that I have is that when I call the Visual Basic program from the Java class, nothing happens. I had the same problem with a Python program, and I thought that the problem was from Python, but now with Visual Basic the problem remains, both aren't executed.
The strange thing is that when I call the same Java class outside Oracle, directly from a command line, it executes both Python and Visual Basic programs.
Here is the Java class defined in Oracle:
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "OSCommand" AS import java.io.*; public class OSCommand{ public static void Run(){ try {
[code]....
And here is the procedure that calls the Java class:
create or replace procedure run_os_command as language java name 'OSCommand.Run()';
I have recently downloaded (the zip file for) OScanner (1.0.6) and have Java JRE installed on my machine. However, I am experiencing some difficulty in running the scanner. how I should start to use this tool, once I have downloaded the zip file.
my java program i am executing a pl/sql function using callable statement i checked everything in the function and the function is created without compilation errors in sql*plus environment, and i gave all DBA permissions to the user, but i got the error like below
java.sql.SQLException: ORA-06550: line 1, column 28: PLS-00201: identifier 'NAME' must be declared ORA-06550: line 1, column 7: PL/SQL: Statement ignored
and i wrote the function like below for the below table
and the java program is like below try{ Class.forName("oracle.jdbc.driver.OracleDriver"); Connection connection=DriverManager.getConnection(dbURL,dbUserName,dbPassword); CallableStatement st=connection.prepareCall("{?=call
I have received a service ticket from QA regarding one of the application forms does not close out even after the exit button is pressed. Instead, it goes to the previous record and continues to do so if there are multiple applications created and then exits at that point.
The end users are not liking that feature and I am unable to detect this error.. What kind of trigger should i apply and what do i write in this trigger.
