Avoid compilationof java class in oracle using load java

we are trying to load dom4j.jar file into oracle jvm using loadjava.
command:
loadjava -verbose -user un/pwd:host:port:sid dom4j.jar
the loadjava utility unzip the jar and loads class files one by one.
most of the classes are marked as invlid.
if i use -resolve option in loadjava
dependency classes are required.
how to make class are valid without using the resolve option or without loading dependent jars.

Try with -genmissing option.

Does Java load a class in caché ? New compiled class are not used .

I run my application (using java.exe + 'my class').
One 'Mybutton' launch a new class Frame based, with one button on it. I see this Frame and close it.Ok.
Now a put a new button in this Frame ( I have 2 buttons then), I save it (and Eclipse compile it).
If a do click on 'Mybutton' I see the old Frame (with one button) not the new Frame with 2 buttons.
What happens ? Is there something like cache class loader? How to avoid this?
My intention is to try to test the changes inmediatly, but in this situation I must to close Myapp and re-run it ?
Some solution?
Thamk you

Java classes are loaded by an Object called a ClassLoader. Each classloader permanently caches all the classes it loads, and always uses an already loaded class in preference to loading a new one.
When a program starts there's already a ClassLoader, the one that loaded your main class. It loads classes from the class path. It exists all the time the program is running.
You can create your own classloaders in the program and if you load your changeable class through one then then you can get a new version by creating a new classloader.
Typically you create an instance of URLClassLoader.
However you need to know that classloaders "delegate" loadClass requests before loading the class themselves, which means that if the class you request is on the class path, your URLClassLoader will get the system class loader to load it and it won't work. You need a special directory (typically called a repsitory) for classes you wish to load multiple versions of.

Pearson put out a tech note on this today - the new versions of Java are what's causing the problem. If you can use Time Machine to rollback java prior to a java 7 or 1.6.0_37 version that will get you going again. I've been searching for hours for a place to download the older version but it seems Apple's site and Oracle all only have the latest release. Still trying to see if I have a copy downloaded on a system that hasn;t been updated to copy off to a network drive or usb and install the older version on to systems.
PowerSchool Tech Notes
PowerTeacher Gradebook and recent Mac OS X Java update
An update to Java for Mac OS X was released on October 16, 2012. An issue has been identified with this Java update (Java for OS X 2012-006) which prevents teachers from launching PowerTeacher Gradebook.
Teachers using PowerTeacher Gradebook should avoid taking this Java update to version 1.6.0_37 until notified that PowerTeacher Gradebook has been certified with this latest version of Java 1.6 for Mac OS X. PowerTeacher Gradebook will continue to work on Mac OS X workstations with Java version 1.6.0_35.
Additional communication will be provided once a workaround is identified or an updated version of PowerTeacher Gradebook is available.

Run a java class in Oracle db to connect to Sybase

Hi All, I'm looking for a way to connect to Sybase database at no-license-cost (meaning Oracle Gateway or similar 3rd party products), first coming idea was JDBC, I know I can run a java class in Oracle, the simple idea is to write a java class which connects to Sybase via JDBC thin driver and return the resultset of given query in a java class, the resultset will be presented in Oracle Apex framework. Does anyone know if this can be done or not, and how? Any howto articles are welcomed.
Henry

Henry:
To connect to Sysbase or MsSQL Server you could use jTDS open source driver.
http://sourceforge.net/projects/jtds/
upload above driver (jar file) using loadjava, and grants the port connection using dbms_java.grant_permission procedure.
Because jTDS is pure java driver (mode 4) is possible to use directly inside the RDBMS.
Best regards, Marcelo.
PD: Latest jtds driver is compiled against 1.6 sources, but oldest version will work with 1.5 for 11g.

Java class in oracle forms

Hello experts,
I am new in oracle forms.I am using oracle forms 11g with weblogic 10.3.5 at windows 7.Someone please clear me that the injection of java programing in oracle forms is through BEANS item only or I can use it(java class) as a part of my oracle forms.I mean I have a Java class.Could I use this java class inside my oracle forms without using Beans Item.
Thank You
regards
aaaditya

In forms you can use java in two different ways
1. On the client-side. Using java-beans you can extend the client-functionality of forms. The code will run on the client-computer in the context of the applet.
2. On the server-side. Using the java-importer you can build a PL/SQL-wrapper around a java-class and so use the java-code in your forms-PL/SQL
What is your reuqirement?

Why Class.forName is used to load the driver ?

Hi all,
Why Class.forName() is used to load the driver ?. Can I use any other method to load the driver safely ?.

Antony Paul

That's still redundant. Sure, it works. Here are some equivalent forms:
    new MySqlDriver();
    DriverManager.registerDriver(new MySqlDriver());
    New LinkedList().add(new MySqlDriver());
    if (new MySqlDriver() == new MySqlDriver())
        System.out.println("department of redundancy department");
    Driver unusedVariable[] = new Driver[] { new MySqlDriver() };
    Class anotherUnusedVariable = MySqlDriver.class; // I'm not 100% sure this works
    new File(new MySqlDriver().toString());
    while (new MySqlDriver() == null)
    new Double(Math.sqrt(new MySqlDriver().toString().length()) / 42);

Loading data from SQL server 2000 to Oracle using OWB 10.2

Hi All,
I have to move data from SQL server to Oracle using OWB. Any idea how to connect to SQL Server thru the OWB design centre console. There is no detail available in the documentation. OWB cocumentation says that "OWB Integrator for Oracle DB & Apps 3.0" is available to connect to Non-Oracle Database (including Sybase, Informix, ODBC).

Hi,
yes, you can use ODBC and configure HSODBC on the database server to create a database link to the sql-server. If your oracle server is microsoft based you are ready, otherwise you have to buy an odbc-driver for linux, unix or whatever you use.

     at …. Call from my class
I suspected multiple definitions of the SerializationContext.class in my jar files but was wrong: there is only one definition in the axis.jar file. For some reasons this jar file contained SerializationContext.class and SerializationContext.java modules, but I resolved this problem earlier: loadjava does not allow loading the both.
What can be cause of the java.lang.IncompatibleClassChangeError problem?
What I have to do to make my class work from Oracle JVM?
Thanks,
Roman

Avi,
You right, at the beginning I had problems with jar files compiled using Java 1.5. But I discovered this problem earlier, when tried to test standalone client application. Since then a whole web services tool kit, provided by my company, was recompiled with Java 1.4 and now I have no problem with standalone classes, running under Oracle JDK 1.4 environment. It means that I’m pretty sure that all Java classes that I’m loading to Oracle are compiled with JDK 1.4.
You also right with your second guess: not all Java objects in the user_objects table of the SAMPLE user are VALID. I started from a scratch (again): dropped all Java objects from user schema and followed Kuassi Mensah instructions from the “Virtualize Your Oracle Database with Web Services” (http://www.oracle.com/technology/pub/articles/mensah_dws.html): I downloaded and then loaded to my schema the Web Service Call-out Utility jar files using the following command: loadjava -u sample/sample@usr10se -r -v -f -genmissing C:\oracle\ora10_DB\sqlj\lib\dbwsclientws.jar C:\oracle\ora10_DB\sqlj\lib\dbwsclientdb102.jar.
This command loaded about 5000 java objects, but 400+ of them were INVALID and I saw a lot of “ORA-29534: referenced object … could not be resolved” errors.
The tool kit provided by the group in my company only increased number of invalid objects.
What is a strategy in this situation?
Do all the objects have to be VALID?
I can try to resolve the “ORA-29521: referenced name ... could not be found” errors by finding corresponding classes in some jar files and loading these jar files, but it does not guarantee that all ORA-29534 errors will go away. What else can I do to cleanup my java objects?
Thank you very mach,
Roman

Avoid compilationof java class in oracle using load java
