Manual Deployment of Java Class's to Database

I was using JDeveloper, now my company has bought JBuilder 4.0, Can any one tell me how deploy my class's manually becuase JBuilder doesnt support deployment=(

You will need to use the loadjava command line facility that comes with Oracle8i. JDeveloper's deployment feature just calls loadjava.
You can find the doc for this in the Oracle8i Java Stored Procedures Developer's Guide, which is available on the Documentation pages of OTN.

Deploy Java Classes to the Database 2

Hi,
I have made a program with JDeveloper, and with the function deploy I can store the code in the Oracle database.
But now I want to use the loadjava tool.
I put all the class files in one jar file and used the following command:
(when I put the .java files in the jar file it works fine, but I want to load the .class files)
loadjava -user test/test@xx–resolve file.jar
The following errors I get:
errors : class test/AnalyzeAccNum
ORA-29534: referenced object XX.test/QueryManager could not be resolved
ORA-29545: badly formed class:
errors : class test/AnalyzeBalNew

In JDeveloper it works fine, and I changed nothing in de code.
What am I doing wrong?
Thanks in advance.

To make it more simple I made a new java file with only this code:
package project1;
public class test {
    public static void test() {
        System.out.println("test");
}I used the following command to make a class file:
javac -source 1.3 -target 1.3 test.java
I used the following command for loadjava:
loadjava -user test/test@database -resolve -verbose test.class
this are the errors I get:
arguments: '-user' 'test/test@database' '-resolve' '-verbose' 'test.class'
creating : class project1/test
loading : class project1/test
resolving: class project1/test
errors : class project1/test
ORA-29545: badly formed class:
The following operations failed
class project1/test: resolution
exiting : Failures occurred during processing
If I do this all in JDeveloper it works fine when i want to deploy the .java file. But when I select the .class to deploy I get this message:

*** Note ***
One possibility for the deployment failure is that the target Database may not support JDK version 1.3. Updating your Project Properties compiler Source & Target to an earlier release could fix this problem.
Someone who knows what the problem is?

Deployment a java class with Oracle92

Good morning i'm a new friend.
Today i have build a java class to send email with attach,testing this class in jdeveloper is all ok,but when i try to deploy into my database i've an error message:
ORA-29545: classe di formato errato: at offset 265 of package1.mypackage.JEmail.SendEmail expecting a class-javax.activation.DataHandler but encountered a class-javax.activation.DataHandler.

How can i do?
Thanks a lot

Hi,
You need to use Integration technology like BlazeDS or LCDS.

Java Class loaded in Database.

hi
I have loaded a Java class into Oracle 8.1.6 database. I have created a procedure (call spec) for calling a method in that class.
It takes 3 parameters (Server ip address, From,To). Actually the purpose of the program is to take parameters and send mails
The Java program uses JavaMail. I have loaded all classes required and the class shows status as valid. When I try to execute the method through a pl/sql procedure it gives the following error.
ERROR at line 1:
ORA-29532: Java call terminated by uncaught Java exception:
java.security.AccessControlException: the Permission
(java.util.PropertyPermission * read,write) has not been granted by
dbms_java.grant_permission to
SchemaProtectionDomain(SANTOSH|PolicyTableProxy(SANTOSH))
ORA-06512: at "SANTOSH.SENDMAIL", line 0
ORA-06512: at line 2
In Dbms_java package there is nothing called grant_permission .
What may have gone wrong ???
Thanks

Maybe you should grant JAVASYSPRIV and JAVAUSERPRIV privilege to your db user
first.
Good luck!

Using normal java classes to access database

Dear friends,
Is it a good practice to make database calls from a normal java class within J2EE environment.
What I meant by a normal java class is a class which is not an enterprise bean.
Best Regards,
Chamal.

it is quite normal.
If you make your own DAOs, it may not be efficient/generic.
JSP/Servlets can use Hibernate (which is a set of POJOs) to access DB. Thus you have a J2EE environment using a very matured DB access methodoloy, and doing away with Enterprise bean.

How to generate the java classes of the database tables

Hi,
I am using Sun One 4 update1 CE for generate java classes of tables from an Oracle database. I have got the database schema file. However, when I right clicked on the database schema file, there is no selection for "Generate Java...".
Besides, when I was trying to use database Schema template from the project tab in the explore window by double click on the project, after following all the procedures of inputing the database url, driver, uername, password, and select the table to generate, the following exception came out:

Auto-deployment of java classes in Weblogic 9 is not working

I have an exploded ear in my autodeploy folder and I am updating some of the java classes inside it. But it looks like weblogic 9 is not reloading new version of them. Did anybody had any success with the similar setup?
And yes, I am updating timestamp for my REDEPLOY file and -Dweblogic.ProductionModeEnabled=false
Thanks,

I think it is missing - you need to do the import on your own. I filed an ER to get this one added.
Note however that the best practice would be to minimize the usage of scripts in your JSP - since this creates spaghetti code that mixes UI with logic and is hard to maintain.

Hot Deploying supporting Java class files

I have a statful session bean that has supporting classes. Is there a way I can hot deploy these into WLS 5.1?

Hi
I guess u r running apache-jserv as servlet engine for your jsp and servlets. If its so, jsp files can be run without any additonal configuration by putting the jsp file under document root or any subdirectory and for running servlets u have to add classpath entries for your servlet in jserv.properties file.
To make sure that your servlet engine is working, try
http://servername:port/servlet/IsItWorking, if u get success msg that means servlet engine is working fine.
Hope this will help

Deploying the java classes

Hello ,
The story:
I have developed a swing application with 3 classes in the same folder , images folders and help files folder which means my folder is like this:
[ x.class - (main class)
y.class
z.class
(images) - folder
(help files) - folder ]
The problem:
I want to distribute the application to user who dont have JDK in their machines , which means they must install JRE .... but the problem is how do i package my application? , how will my users run it ?
please help !!! i'll appreciate that , thanks.,...

A JRE is definitely required, either advise them to download a free copy from sun or package it together with your application using InstallShield

Deploying java class that uses oraclexmlsql.jar

Hi,
I'm trying to deploy a java class that I wrote. It simply gets some data out of my oracle database as xml using the oraclexmlsql package. It works fine when I compile it within JDeveloper.
When I try to deploy it JDeveloper gives out the following error:
Errors in xmlquerydb:
ORA-29521: refferenced name oracle/xml/sql/query/OracleXMLQuery could not be found
loadjava: 1 errors
I can't figure out why that happens. I have used other classes and deployed them as Java stored Procedure and they work fine.
Thanks for help
Andre

I tried to load the oraclexmlsql.jar into the shema where I put my class. The classes from this jar were loaded but can not be compiled( apart from 3 ). I also tried loading my class into sys but I still can't compile it or the oraclexmlsql.jar classes.
Is the xsu12.jar a collection of all the classes that are allready in Sys after the database install?
I have noticed that on expanding the oraclexmlsql.jar file has a strange format and two classes classes are in the directory from which I expanded the jar. These two classes do not get a synonym on loading into the db. Could that have anything to do with it?
Thanks for more help

Download jar / java class from database

Hello,
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.
Can you tell me 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)
Thanks for some tips

Can you tell me how can I download some java classes from database?You can use dbms_java.export_class procedure to export class as blob, then just save the blob to file.

Drop java class not working

Hello,
i'm using a freshly installed SQLDeveloper 1.5.1 to a java class to the database. Loading the class works, i can see my class in the tree under java.
Now i wanted to change the source code of my class, so i wanted to drop it in the database. But although SQLDeveloper tells me that the Java Object "MyClass" has been dropped, it is still there in the tree. When i click on the entry in the tree i can still see the code.
What do i need to do to remove my java code from the database?
Thanks for help in advance,
Dirk

Hi ,
select XMLTOOLKIT option in Operation mapping and execute it.
I am not sure we can call java program in XSLT Program,but alternative is copy the code and use it in XSLT mapping it self,that means your XSLT program will become with JAVA extensions.
then in Operation mapping level select SAPXMLTOOL kit option and execute it. i hope it will work. if it is not working then you have deploy some JAXP files on server,because the way execution of XSLT Mpaping program got changed,like when eve you executing XSLT with extnasions( if you are not using XMLTOOL kit option) then you have to use latest version of JAXP.JDK files.

Custom java class in Quoting screen Customization

Hi,
We are working with Customization of couple of screens in Quote module. Esp. the Create Template screen. We decide to add new property to the Template and user needs to choose among a set of values to this new property through a radio button.
Instead of hardcoding these property values and radiobuttons, we thought we would define these data in some lookup table and fetch them and display.
Now, since we are defining these lookup data, should we write our custom java class to interact with database and fetch them from any lookup table (should we use flex fields ?) ?
If we are going to write custom java object, any guidance on how to compile/deploy/standards for them ?

Since our this requirement is in Quotes module, its not using OAF. It is using plain JSPs and java classes.
What i was thinking is, create the Option values as flex fields, and write a custom java class to fetch these data from the flex tables and use it in the JSP.
The main problem we are facing now is,
"...we wrote a simple java class, which establishes database connection, executes a simple insert & select query to our custom table. compiled & placed the class file under our new pkg structure under $JAVA_TOP eg. oracle.apps.xxx.quot.tmpl , bounced the apache."
But when we tried to import this class in the jsp (which is being customized), the app just throwed Internal Server Error and we couldnt find any info in the Log file.
Couldnt guess, why is this simple thing failing. Any idea ?

Drop all java classes

Hi there folks,
I'm facing a rather nasty problem: I have deployed a number of
java classes to the database via loadjava while the rest of the
team were still developing away.
To delete classes via dropjava you need the file they were
loaded from (e.g. a .jar file). Now the .jar files have changed
during the development and using dropjava with them will leave
some files in the database.
Is there a way to get rid of all classes in one scheme without
the source files?
TIA,
Joerg

list all your java classes by cursor
select object_name from all_objects where owner='SHEMA' and
object_type='JAVA CLASS'
and for all object_name execute
drop java class "object_name"
