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.

How to download a java class from database to file system

Hi All,
We have one invalid java class in database. We need to verify what is the functionality of this class. So we planned to download this class to file system. Then we need decompile it to source. But we are not able to identify the right command to download the java class from database.
Please suggest me if any possible ways to acheive this.
Thanks in advance....

How to call Java class from Forms 6i?

Hi friends,
I need to call a Java class from my Forms 6i application.
(It runs under WIndows XP. It's a client/server application and I have only the client and the Form builder installed on my PC)
I don't know almost anything about Java's world so your help would be very useful for me.
Could you tell me exactly what i have to do?
I've read in metalink several Notes, but they supposed that the Java architecture is already installed in the computer.... I only have the default installation of Developer 6i... so I would need to know:
- How to install/configure the neccesary to execute Java classes without problem
- How to invoke the .class from Forms 6i.
Thanks a lot
Jose.

And also this one:
Problem Description
Installed Forms 6i Rel 2 on a MS Windows machine. When trying to Import the Java
Classes getting the errors
PDE-UJI0001 Failed to create the JVM
Solution Description
You need to to install JDK 1.2.2 to run the Java Importer. And set the PATH's
and classpath's correctly.
Explanation
1. Download and install the JDK 1.2.2.
Possibly available at: http://java.sun.com/products/archive/
2. Assuming the JDK 1.2.2 is installed in c:\jdk1.2.2 directory and the JRE in
C:\PROGRA~1\JAVASOFT\JRE\1.2 directory; ORACLE_HOME=C:\Dev6iR2.
Set the PATH to
set PATH=c:\jdk1.2.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin\classic;%PATH%
( If you are using ias9i then the JDK 1.2.2 comes with the ias installtion ,
in this case please set the PATH to
D:\ias9i\Apache\jdk\bin;D:\ias9i\Apache\jdk\jre\bin;D:\ias9i\Apache\jdk\jre\bin\classic;%PATH% )
3. Set the CLASSPATH to set CLASSPATH=%CLASSPATH%;C:\Dev6iR2\TOOLS\COMMON60\JAVA\IMPORTER.JAR;.
(If you do not set the CLASSPATH correctly you will get the error
PDE-UJI002 Unable to find the required java importer classes)
4. Now run the Forms Builder by using the command.
C:\Dev6iR2\bin\ifbld60.exe
Now the Java Importer Should Run fine.

How do I call a simple java class from a bpel process?

Hi.
In JDeveloper 10.1.4.3.0 I've created a simple java class that does an ftp get operation followed by an unzip. The class uses some 3rd part libraries (jars).
I want to use a simple bpel process to schedule a daily execution of this java class, and deploy it all to our SOA-server, - and was looking into using the <bpelx:exec> function.
The java class and the bpel process is all stored in the same JDeveloper project.
How do I put this together so that both my java class and the necessary jars are available to the bpel process?
I've looked into the JavaExecSample.bpel, and it's says something about "...the class com.otn.samples.javaexec.CreditCalculator is locally packaged with this BPEL process".
How do I do that?
Can I make it and test it all locally from my workstation (only JDeveloper installed, I guess there's nothing that can execute the bpel code?), or do I have to compile class etc (make war-file?) and deploy to SOA server (BPEL-INF/lib or classes?) before anything can be tested?
(I guess all this is simple, once you know how, but being a newbie to this I need a shove in the right direction :-)
Regards,
-Haakon-

To create a java class and dependent jars inside the BPEL process project you need to do the following:
1. Right click on your BPEL process project and select New and then Java Class from the Items.
2. Make the BPEL process project, JDeveloper would compile the java classes and add them into the BPEL suite case jar, see the output folder and check the BPEL suite case jar file for java classes and dependent jars.
You can test your Java classes from JDeveloper IDE, no need to deploy the classes on SOA server. When you make the BPEL project it compiles .bpel files and Java classes. You can test your classes once .bpel file and java classes compiled successfully.

Calling a Java Class from PL/SQL

Hai,
I need a technique of calling a class file and invoke its
methods written in Java by PL/SQL for my intranet development.
PLease let me know if you have really experienced and won.
Thanks
JOhnson

First, to call a Java class from PL/SQL the class needs to be
deployed to the database. you can check the 8i documentation for
the instructions for loading Java into the database(LoadJava).
The document contains information on how to load the Java and
call it from PL/SQL. The following links should help.
Loading Java:

I want to call External Java class from the PL/SQL

Hi,
I am using Oracle Apps R11i (11.5.7), I wanted to call external Java class from the PL/SQL. This external Java class is residing in another application server.
How do I do this.
I know one way. Develop C routine in Oracle Apps to call external java class and call this C routine from the PL/SQL.
Is there any simple method available? or any other method?
Thanks in advance.
-Venkat

First of all, this is a Java application you're talking about, right (i.e. it has a main() function)? It's not just a class that you're trying to instantiate is it? If it's an application, you obviously have to start a new virtual machine to run it (rather than using the virtual machine built into the database like stored java). I'm a little leary of your mention of an "application server" as this would more commonly mean that a virtual machine is already over there running with access to this class. In which case, you'd typically interface with SOAP or some other RPC API.
All that aside, as long as you have physical disc access (through NFS or whatever) to the class file, you could use a java wrapper class with a system call to do this. In fact, there is a thread in just the last day or so on this very forum that has the code to do just that (see " Invoking OS Commands from PL/SQL"). However, it's worth noting that the virtual machine will be running on the database server in this case and not the application server.

Calling Custom XSLT java class from BPEL in SOA Suite 11g

Hi All,
Morning...need some help with this issue...we are currently on SOA Suite 11g (11.1.1.4) version.
Earlier while we were on SOA Suite version 10g (10.1.3.3) we were calling the custom java classes from the xsl mapping for complex transformation and for this we were placing the .class file as .jar file at the location mentioned here $OC4J_HOME/j2ee/home/applib directory and then mentioning the namespace as http://www.oracle.com/XSL/Transform/java/{$classname$} in the XSLT mapping file.
Now in SOA Suite 11g if we need to retain similar functionality for external custom java calls could someone please help us where do we need to put the .jar file now ..
exactly at which directory location/path and on which instance/server (application server instance or middle tier instance ) we need to put this .jar file
Currently we are stuck and need some help with this.
With thanks & Regards

Hi Eric & Anuj,
Thanks for replying , sorry for checking on this now...
here at this path /opt101/app/oracle/SOAD/SOA11gR1/fmw/Oracle_SOA1/soa/modules/oracle.soa.ext_11.1.1
we got the ora.soa.ext.jar file and extracted it to get the MANIFEST.mf file ..have mentioned below.
Now if we need to link our custom .jar file named customfunctions.jar so we need to mention it as below is this correct :
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.1
Created-By: 17.0-b17 (Sun Microsystems Inc.)
Implementation-Vendor: Oracle
Implementation-Title: Oracle SOA EXT
Implementation-Version: 11.1.1
Product-Name: Oracle SOA EXT
Product-Version: 11.1.1.4.0
Specification-Version: 11.1.1
Extension-Name: oracle.soa.ext
Class-Path: classes/
Class-Path:customfunctions.jar classes/ -- is this the way to mention (means we need to add this additional line or we need to add to the existing line at Class-Path: classes/)
2.
Eric the Alternative method mentioned in your update :
Open a command prompt and change the current directory to the oracle.soa.ext_11.1.1 directory ,
then execute the build.xml file in the oracle.soa.ext_11.1.1 folder using Ant
Now could someone please guide us regards this ANT means how does it work and its relation to the build.xml file and how do we check whether we have ANT utility available or not..
not much conversant with this ANT hence asking here..would lookout for your reply
thank you

Trying to invoke a Java class from BPEL Proces using Java Embedding

Hi All,
I have a requirement to invoke a Java class from the BPEL process;
I am trying to import the class by "* <bpelx:exec import="+package_name.classname+"/>*.
But, while compiling, I get the following error:
"Error(19,57): Failed to compile bpel generated classes. failure to compile the generated BPEL classes for BPEL process "BPEL_PROCESS_NAME" of composite "default/COMPOSITE_NAME!1.0"
The class path setting is incorrect. Ensure that the class path is set correctly. If this happens on the server side, verify that the custom classes or jars which this BPEL process is depending on are deployed correctly. Also verify that the run time is using the same release/version."

And here I m not finding as jaxb-libs.jar,namespace.jar and jax-qname.jar on respective location.
If I m putting these left jar file from another place it is not generating all the classes as at least in number it should be 45 but it is generating merely 5 classes.
Can any one help me regarding this.

Errors generating Java classes from XML schema

I received the following errors when generating Java classes from the schema located at: http://imsproject.org/xsd/ims_qti_rootv1p1.xsd and http://imsproject.org/xsd/ims_xml.xsd
XML Spy v4 claims that the schema is well-formed and valid. Could this be a problem with the class generators, or is XML Spy not telling the truth?

Is it possible to invoke a Java class from Data Services 4.0?

Is it possible to invoke a Java class from Data Services? I have a query transform with a varchar column which I want to run an external java class against to encrypt the string value. In the Management Console, I created an adapter of type TestAdapter and referenced my jar file in the Classpath section, but when I create a Datastore of type Adapter I can't import any functions related to my java class? It seems like I need to create a new Adapter type similar to the TestAdapter with the 'Adapter Class' set to my java class? I can't figure out how to do this - which is the correct approach and is there some documentation available? thanks!

First u nees to imoprt the class which u are doing right
then u need to call the function of the class , and then you can put the value in a string .
DbCon.function()
String data = DbCon.db;
where db is a string in DbCon
Cheers

Calling java classes from plsql procedures

I'm attempting to call java classes from plsql procedures which will create cmsdk users, folders, groups etc, however when I attempt to load a java class into the oracle schema using the command:
loadjava -user user/password@database -resolve classname.class
It generates error messages to the effect that classes (cmsdk classes) required by the class cannot be found. The class is loaded and marked with the status "invalid". Is it therefore necessary for me to load the cmsdk packages into the schema?
Cheers
David

Using CMSDK Java API within the database has never been supported
(see Problems loading IFS's java class into database
When we needed to invoke CMSDK code from our PL/SQL code, we used one of two approaches:
(1) use advanced queues to send requests to an external Java program (the CMSDK code, running outside the database) and receive the results back (asynchronous choice); or
(2) make an HTTP request to a Java servlet (the CMSDK code, running in some Java web container like iAS) and get the response back in some custom format (XML or something) (synchronous choice).
It seems to me that the CMSDK Java API was designed to be used only in middle-tier, not in database tier.

Calling java-class from c++ misses

Hello,
if I call a java-class from c++-code and the java-class imports a package (not java packages, but writen by myself), then the calling misses :-(
If I call this class without the imports - it works!
C++-Code:
    jclass cls = env->FindClass(javaClassname.c_str());
    if (cls == 0) {
          //error     - cls is 0 if the java-class has imports
    }Java-Includes:
import mypackage.Conn;
import mypackage.Para; I set the classpath to the .jar-files. Did I forget anything else?
Thx...

From the JNI Specification: http://java.sun.com/j2se/1.5.0/docs/guide/jni/spec/jniTOC.html
=======
FindClass
jclass FindClass(JNIEnv *env, const char *name);
This function loads a locally-defined class. It searches the directories and zip files specified by the CLASSPATH environment
variable for the class with the specified name.
LINKAGE:
Index 6 in the JNIEnv interface function table.
PARAMETERS:
env: the JNI interface pointer.
name: a fully-qualified class name (that is, a package name, delimited by �/�, followed by the class name).
If the name begins with �[� (the array signature character), it returns an array class.
The string is encoded in modified UTF-8. ==============================
So, to find the Conn class, you need to use:
env->FindClass("mypackage/Conn");

Is there an easy way to call a java class from an applet?

Does anyone know of an easy way to call a server based java class from an applet? Has anyone done it or came across it? If yes how/where?
Cheers, Chris.

I'm not sure about the issue. Are you talking about "servelets"? "RMI"? Take a look at those issues.
