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.

Running a Java Class in Apps Server?

Does anyone have a clue how to just simply run an existing *.class using Oracle Apps Server as the web server listener?
I'm assuming there is some default path that I should place my *.class file in??? Or some unique way to call it from the <applet> tag???
null

Thanks your response. I'm on sp3.
The application is "Factory".
The Java Project in "Factory".
In the Java project there is a folder "pac", in that folder there is a class with a main method called "ProviderClient"
In the "Factory" Java project properties/debugger window, Build before debugging is checked, also Create new process. Main class: pac.ProviderClient
Home directory: C:/bea/user_projects/MyApps/Factory/Factory/
(It was put there autopmatically when I clicked Browse as you said).
When I run I get:

How can I compile and run other java classes from within an application?

Hello there everyone! I really hope that someone can help me. I am writing a program that must be able to compile and run other java classes that are in different files, much like development environments like Kawa or Forte allow you to do.
There has to be a way of doing this ( I hope!! ), but i can't seem to find it!!
I have tried using this command to compile:
Runtime.getRuntime().exec ("c:\\programs\\javac className.java");
...and this one to run:
Runtime.getRuntime().exec ("c:\\programs\\java className");
...but neither works!!! I can compile and run classes that are in the same file as my application, but I can't get it to work at all for files in different directories or files.
PLEASE, PLEASE, PLEASE help me - i've run out of ideas, and i need this to be working in 3 days!!!
Thank you very much for any help anyone can give me, I really appreciate it!! Thanks again!!
Adrian ( ...in distress!! )

public class JavaCompiler{
   public static void main(String[] args)throws Exception{ //sorry bout the laziness
      if(args == null || args.length != 1){
         System.out.println("Usage: java JavaCompiler MyClass.java");
         System.exit(0);
      String className = args[0];
      Runtime rt = Runtime.getRuntime();
      Process p = rt.exec("javac " + className); //consider setting cpath for this
      p.waitFor();
      //now try to run after it is done.
      p = rt.exec("java " + className.substring(0, (className.length() - ".java".length()));
      p.waitFor();
      //do some other stuff
}This should get you going. You may consider looking into the System.getProperty() method in order to determine the type of OS it is running on in order to findo out what command to run. I know that the sun tool listed above is nice, but by my understanding the sun tools provided are not guaranteed to stay the same. I'm no expert on this matter, but that is one of the reasons there is no API documentation for those tools. Also, I don't believe those tools come packaged with the JRE. (Of course if you are making an IDE it will be expected that the user has an sdk installed. Good luck with figuring this thing out.

Running a Java Class in Workshop

I'm trying to run a Java class with a public static void main method in Workshop. As instructed I opened the properties for the Java project, under the debbuger tab, checked Build before debugging. Then under "Create new process settings", in the Main Class box put the class with the main method with proper package structure. Clicked Ok. When I click the start button, the project builds, the process starts, the last message in the Output box is "Process Started" but then nothing happens. No System.out.println statements show. If I set breakpoints it never gets there. No values ever get set or changed in the Locals box. What am I missing?

Thanks your response. I'm on sp3.

Can we run a java class in a external server through abap program?

Dear Experts,
Can we run a java class in an external server ( other than application server and client system )?
I have tried running it in the client system through a program and it works.
But i have the requirement of running it in another system. Can it be done?

Hi,
If this is the case I think you can call this web service from SAP and triger the execution of the application on the "external server".
SAP is behaving as a client in this case.
Another alternative:
"have tried running it in the client system through a program and it works." please elaborate.
Regards.

I have imported .class file into CMC and trying to invoke the .class file by another java program from eclipse..When i tried to invoke the .class in cmc, i am getting an error msg, mentioned above. I thought there might be version conflict. So i changed the java complier version to 1.5 in my Eclipse. After that is done again i am facing the same problem.
Can anyone help me to resolve this issue?
Thanks in Advance.

i have installed BO SDK 3.1 , Service pack 3. It comes woth JDK 1.5 version. i have not done any chnages to it. I impoprted all the jar files related to BO into eclipse.
1) Actually, i am writing java code on eclipse. When i run code from the eclipse, it creates a session to cmc and creates folder structure what i need.
2) But the thing is, that code needs to run, when i import the .class file into cmc. The process how i imported the .class file to cmc.
Manage> Add> Program File-->Java (Check Box). In this way i added java class file from the eclipse workspace (class file from the bin directory).
3) So when i run the .class file externally by another java program or also when i log in to CMC and run that .class file, the instance shows sucess, but when i see the logfile i am getting an exception that which i mentioned above.
If my method is worng can you please let me know the stepts how to run java program in cmc.
Thanks in Advance

Oracle Gateway Not Connecting to Sybase database

Hi,
I'm trying to setup an oracle gateway to connect to Sybase database. I followed in details the instructions but still can connect successfully. The Oracle database is in RAC environment. Below are the steps I took:
The oracle gateway and oracle database are in the same server while Sybase is on a separate unix box.
1. create an initdg4sybs.ora file
# This is a customized agent init file that contains the HS parameters
# that are needed for the Database Gateway for Sybase
# HS init parameters
HS_FDS_CONNECT_INFO=[999.99.108.99]:4527/common ## IP address of sybase server
HS_FDS_TRACE_LEVEL=ON
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
2. create a listener on the oracle gateway home
# listener.ora Network Configuration File: /u03/app/oracle/gateway/11.2/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER_DG4SYSBS =
(DESCRIPTION_LIST =

3. create tnsnames.ora in oracle database home
dg4sybs =

(SID = dg4sybs)
(HS=OK)
4. create database link
create database link dg4sybs connect to "user" identified by "password" using 'dg4sybs'
5. when testing the connection; i'm getting below error message. tried all the setup based my research and couldn't make it work.
SQL> select * from dual@dg4sybs

I perform above settings on a standalone database running in windows and successfully connect to the sybase. In UNIX setup, been unsuccessful. Can someone please help.

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?

Java class in Oracle 8i.

Hi All,
I have tried to create a java class in Oracle8i but it throws some errors like:
NAMED "MyTime"
ERROR at line 3:
ORA-29516: Aurora assertion failure: Assertion failure at eox.c:187
Uncaught exception Root of all Java exceptions:
The program is :
CREATE OR REPLACE
JAVA SOURCE
NAMED "MyTime"
AS
import java.lang.String;
import java.sql.Timestamp;
public class MyTime
public static String getTime()
return (new Timestamp(System.currentTimeMillis())).toString();
Please give a solution ASAP.
If anybody knows give me more information about how the classes are created in the database and how itz get compiled.
Thanks in advance.
Rajesh

Anurag,
Here's an example of one I wrote which is VERY simple. Sometimes it helps to crawl before tou walk. You can execute the following using SQL*Plus:
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "RuntimeExample" AS public class RuntimeExample {
public static String runNotepad() {
String returnValue = null;
Runtime r = Runtime.getRuntime();
long totalMemory = r.totalMemory();
try {
     Process p = r.exec("notepad.exe");
     returnValue = p.toString();
     } catch (Exception e) {
          System.out.println("Exception calling Runtime.exec()->" + e);
     /* You can get creative here and
     1) Use p.waitFor() to block while the process is running,
     2) Send the command to be executed as a parameter to the method, etc. */
     return returnValue;
Notice that I return the string equivalent of Process p. This tells you if a process was really started.
Hope this helps,
-Dan

How to run a Java class in JDeveloper - with Input parameters

Folks,
I need to run Forms 10g trace and do not have access to the Dos command line (no Programs-ACcessories-Comand prompt). I am allowed to run Batch files though.
So really I need to run class "oracle.forms.diagnostics.Xlate", but need to give Input Parameter to this class. I know to load JDeveloper and open this class, but when I execute it it gives me the following error.
My question is HOw do I input the File name to this Class when I execute it from JDeveloper.
ERROR: You must specify an input datafile
Exception in thread main
java.lang.NoClassDefFoundError: oracle/forms/registry/MessageManager
     at oracle.forms.diagnostics.Xlate.printUsage(Unknown Source)
     at oracle.forms.diagnostics.Xlate.readArgs(Unknown Source)
     at oracle.forms.diagnostics.Xlate.<init>(Unknown Source)
     at oracle.forms.diagnostics.Xlate.main(Unknown Source)
Process exited with exit code 1.

To specify program arguments
1. Select Tools>Project Properties.
2. Select Run/Debug.
3 Select the Default Configuration and select Edit.
4. Specify the program arguments in the Program Arguments field.

Error while importing java class into oracle forms 10g

Hi
I have generated a web service client using jdeveloper 10g. It consists of complex type methods. I am trying to import the class files using java importer in oracle form 10g. I am able import all of them successfully except one. That one is the main method. Please see the error and suggest me how to overcome this error.
Exception occurred: java.lang.NoClassDefFoundError: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub
Thanks in advance

Do you see oracle/jdeveloper listed in "Import Java Classes" when you try to import?
If not, make sure you add C:\DevSuiteHome_1\jdev\lib\jdev.jar to FORMS_BUILDER_CLASSPATH in registry
Also excetion indicates: oracle/jdeveloper/webservices/runtime/WrappedDocLiteralStub
If you typing it - type: oracle.jdeveloper.webservices.runtime.WrappedDocLiteralStub

Running a java class from a windows shortcut?

I am currently running a program I have written from a batch file for which I have created a shortcut. I have recently however modified my shortcut to include a variable that i pass to the main method in the program through the batch file - all this works fine.
It did however get me thinking - why can't I do away with the batch file??
Below is the batch file code that loads my software:
Echo Off
CLS
SET CLASSPATH=.;"C:\Program Files\Java\j2re1.4.2_03\bin"
SET Path="C:\Program Files\Java\j2re1.4.2_03\bin"
C:
CD\
CD "Program Files\My App"
start "My App" javaw My_App %1
And the two shortcut strings that call the batch file:
"C:\Program Files\My App\My_App.bat" var1
"C:\Program Files\My App\My_App.bat" var2
What I have been trying to do however, is do all of the above from the shortcut
I have added the following code to a shortcut:
Target:
C:\WINDOWS\system32\cmd.exe /c SET CLASSPATH=.;"C:\Program Files\Java\j2re1.4.2_03\bin" && SET Path="C:\Program Files\Java\j2re1.4.2_03\bin" && start javaw "My App" My_App
Start In:
"C:\Program Files\My App"
All of the relevant paths are set correctly, and it calls the main java class file from the directory from where it resides, but I get a popup error message stating:
Java Virtual Machine
Error: Could not fing Java 2 Runtime Environment.
Has anybody got any ideas on how to fix this please??

Either I'm misunderstanding, or ?
You don't need to set classpath if all you need for a classpath is the directory that contains the classfile - the Start in combined with -cp . // that's -cp followed by a periodsets the classpath to that value, and Windows will create a fully qualified path to javaw.
You entries in the shortcut shouldn't have to be any more than what I typed.

Running/Compiling *.java file in Oracle Sql Developer

I want to compile/run java 5.0 files in Oracle sql developer1.1.2.25 on Fedora 5 platform.
I have added javac as an enternal tool to compile java programs. Tools-->External Tools-->New
I have also added java: /usr/java/jre1.5.0_10/bin/java as an external tool to run the complied programs
I am able to compile the java programs, but i am not able to run them.
I am providing ${file.name.no.ext} as an argument to java.
Java-Log Output is:
/usr/java/jre1.5.0_10/bin/java Writer2
Exception in thread "main" java.lang.NoClassDefFoundError: Writer2
However, if i run the same program in Linux terminal, i get the correct output:
[root@localhost java]# which java
/usr/java/jre1.5.0_10/bin/java
[root@localhost java]# /usr/java/jre1.5.0_10/bin/java Writer2
12
howdy
folks
How can i make Oracle Sql Developer run the java program?

I will echo the use jdev comment..
Regardless, you may want to check the execute in directory.. or add a -cp parameter.
