Generate IDL from Java Code, Classes, UML, etc?

Hi,
is is possible to generate IDL code from Java Code, Classes, UML, ... using JDeveloper?
I know this is somewhat reverse engeneering, but it would speed up the migration of our existing Java project...Unfortunately it does not. The IDL to Java conversion is handled under the covers by the idl2java.exe included with the database. You might want to search on google for a IDL generator from java source.
java2iiop (another tool) just generates IIOP stubs from classes and interfaces, but I don't think it creates IDL.

Can u access Oracle9i Reports objects from Java Code?

Hi,
How can you access Oracle9i Reports (Rel 2) objects like Body, DataSource, Groups etc from Java Code?
What are the available APIs?
I went thru the APIs at http://otn.oracle.com/products/reports/htdocs/getstart/docs/Javadocs/oracle/reports/plugin/definition/package-summary.html
However various constructors stated in these APIs are using classes from "oracle.reports.definition" package which are difficult for me to locate.
For eg. Report constructor is using oracle.reports.definition.RWReport and there is no API documentation available for RWReport class.
Please suggest me the site for the above APIs or the method to get a reference to "Report" instance.
Thanks
Rakesh.

Thanks Tugdual for your quick reply.
Thats exactly what I am trying to do. I want to develop a utility which can have a subset of Report Developer's functionality.
Currently using Reports Developer & Report Wizard, I can create a report by providing SQL statement and few parameters (like Report Style, Calculated Fields, Template file etc). I want to put all these parameters in a XML file and run my java utility (based on the APIs which I am looking for) which will use these XML parameter file and generate a '.rdf' file.
Also, could you please suggest me the site for oracle.reports.definition package API or the way to get a reference to oracle.reports.plugin.definition.Report instance.
Thanks,

Convert java code into UML

hello,
anybody knows a software convert java code into UML? Classes Diagram.
for example JBuilder do that.
// i use Netbeans.

its not a speed issue although sometimes it can be painfully slow (but now slower that sun one). I constantly found myself getting into infinite error message loops (e.g. "incorrect input"... click ok... "incorrect input"... errr click ok.... "incorrec..." etc etc), and also it (relatively) regularly falls over. I tried to export diagrams as GIFs, and when I imported them into Word they looked ok, but when I printed them they printed negative!! I used about 100g of toner before I realised, and had to go thru all diagrams changing them to JPGs. Plus, I think the interface for 6 is a lot less intuitive than 4.2, and it's trying to be too feature rich. Personally I would never use it as a code editor as it's too big and lumbering. For me, it's a diagramming tool, but it doesn't even put pretty pictures as nodes on deployment diagrams!! I want pictures of workstations, PDAs and databases!! Only kidding...

Starting exetutable java file from java code

Hi I was wondering how I can start a executable java file from java code?
thanks

Hi Mkaveli,
Yes, it's possible. If you have a JAR executable, you've just to call the main method of its starter class. For a simple executable class, just call its main method.
This way :
SomeStarter.main(null); // if there's no argumentSmall precision : the executable JAR or class must be specified in the classpath of your application.

Hi,
Back in 2003 I have used an Applet which contain java code and this java code was calling the java scripts ( different methods, DHTML etc..)
There was a component developed by NetScape called JSObject I am not sure it there is other third party component other then the JSObject
look at this article which shows how (based on JSObject)

Yes, the network connection could not be established. Like the error said.
What you're asking about is the exact reason, but that could be any number of things and not at all related to code. You could have the wrong host, the wrong port. A firewall could be blocking the outgoing connection, a firewall could be blocking the incoming connection. Etc. etc.

Executing a DDL statement from java code

Hi all,
this is code from jdev11.1.1.3 version. I am trying to execute a DDL statement in oracle db from java code, but "ORA-00900: invalid SQL statement" error is coming.
I am trying to create a table in same schema in same db by using 'Copy' command.
Same DDL command is executing from sql command prompt & table is being created. Plz help me , as how to do from java?
        public String cmb_action() {
        // Add event code here...
        try {
            //getting source db connection
            InitialContext initialContext = new InitialContext();
            DataSource ds = (DataSource) initialContext.lookup("java:comp/env/jdbc/SourceConnDS");
            Connection sourceconn = ds.getConnection();
            sourceconn.setAutoCommit(false);
            String sql = "Copy from myschema/mypass@DB insert t_dept using select * from dept;"
            Statement stat = sourceconn.createStatement();
            stat.executeUpdate(sql);
            sourceconn.commit();
            System.out.println("done");
          catch (Exception ne) {
            // TODO: Add catch code
            ne.printStackTrace();
        return null;
    }

I have a requirement to transfer data from one db to another db from Java Application Layer.Maybe, maye not. We get all sorts of weird "requirements" - which are nothing but thoughts or proposed solutions.
But,
Did the "requirement" mention whether the table existed already or not in the target database? - If not, did it tell you to create it - drop/create it?
Did the "requirement" deliver some explanation to why this copying was neeeded? - Are we talking replication? - Or a one time cloning?
Etc, etc,
Personally I would always argue against a "reuirement" like that. - It just isn't the way to do it. Period.
Regards
Peter
P.S: If you are satisfied with what COPY does, then you could let Java make an OS call and do it from there?

Clear the Filter Criteria from java code programmatically

Hi All,
I am using jdev version 11.1.1.6.0.
I do have ADF table for which I have added filter to each column .
I created table using java class data control.
Filter is working Fine .
My use case is-
When I click on search button data is populated in table.
When anybody enters filter value in column suppose product and hit enter ,it filters data.
if he clears and do not hit enter key and search again then it does not show all data it only show filtered data.
So how can I programmatically clear all filters so on click of search it will show all the values not filtered values.
I have not used default Filter Behavior.
Please check below code for reference

Create web service from java code in Jdeveloper 11.1.1.5

I am try to create web service from java code by default it is connected to Integrated web logic server and generate a
WSDL like this.
http://localhost:7101/javaexcel-project1-context-root/MyWebService1Soap12HttpPort.
please tell me how we can change this local host to our needed Host and how to deploy this web service to web logic server.

Hi,
Just right click on your project and deploy it to your application server (Weblogic Server (Not the Integrated server)). {Before that, you have create your Application server connection in the Jdeveloper).
After deployment open the Admin console of the weblogic server and find your ear of the project.Click on that (Go to the "Testing tab") and you will get the "WSDL" (Concreate wsdl) and "Test Client" of the Project.

Executing system commands like cd on Linux from Java Code

Hi,
I need to execute a few system commands (like cd, ls, tar, etc.,) on RedHat Linux 7.1 from Java code. Any ideas plz.
best wishes,
Issac

Since this thread mentioned using the DOS START command
from an exec(), I was wondering whether anyone else is
seeing the odd behavior I am.
Most of the examples showing how to read stdout and stderr
while the process is running show simple loops that use
getInputStream and getErrorStream and do read's until they
get back -1. Most of these examples are insensitive to the
state of the Process.waitFor that happens elsewhere and sort
of rely on the -1 and the waitFor happening roughly together.
Whenever I use this technique to launch an arbitrary DOS
command (e.g. Runtime.exec("dir")), it works fine, and
everything seems to terminate as expected.
However, when my command is something like:
Runtime.exec("cmd /c start my.bat")
where I deliberately use the START command to fork off
a different process, something odd happens.
Those simple read loops get an initial burst of stdout/stderr
bytes from the "start" part of the command. But then eventually,
these loops do a "read" which blocks on those InputStreams. Now,
even if my Process.waitFor returns (because the start returned
immediately), those read loops stay blocked **until that script
started by 'start' runs to completion**. It is like the child
of the child is holding those streams open somehow.
I found that by doing something like an InputStream.available() or
a BufferedReader.ready( ) check before dropping into the read,
and allowing the Process.waitFor completion to exit those read loops,
them I get what I expect -- namely immediate return from the START,
but apparently complete copies of stdout and stderr.
Curiously, in the case where the reads block until the child process
started by START terminates, they still don't get the child's/child's
stdout and stderr. It is just a long duration thread block that
yields no data.
Can anyone explain what is happening to a
Process.getInputStream( ).read()
when the process immediately does a START and returns? Why would
the read( ) stay blocked when the START finished launching a new child
process?

How to find particular CRM BAPIs from Java code of ISA B2B application?

Hi Guys,
I am newbie in CRM ISA field. I am supporting CRM ISA 5.0 B2B application.
Basically I had a question about how to go about finding the BAPIs which are getting called from the Java side of ISA.
I know that the framework uses JCO connection in order to execute BAPIs in the back-end and usually these BAPIs are standard.
So I can put a break-point on the CRM bapis and see which is called when.
But if I want to track BAPIs from Java code, what should be my approach?
Please help.
Thanks!

Hi,
To setup the trace logs you need to use the following URL.
https://<system domain name>:port/<application_name>/admin
typically it should look like as below:
https://abc.com:50001/b2b/admin
Here there is an option to start and stop the logs and after stopping it will generate a Zip file which you need to download and from there you can easily find out the BAPI's or teh RFC calls.
Also when you search you should alwways keep one thing mind that these FM's normally start with CRM_ISA*
Hope it helps.
Regards
Sidd

Running sqlplus scripts from Java code?

hi
I need to programmatically run sqlplus scripts from Java code on a machine that doesn't have sqlplus installed.
Is there any Java class library available for doing this?

The Ant approach could probably work for me, thanks for the tip.
The setup seems rather complex however, given the simplicity of the task. I would prefer just running a Java based SQL*Plus from in a separate process or doing this via an API that would allow me to run SQL*Plus scripts (parse script, substitute variables, run statements).
Oracle SQL Developer v1.1 appears to include an API that does exactly this.
The ScriptParser, Substitution and SQLPLUS classes in the oracle.dbtools.raptor.scriptrunner package (oracle.sqldeveloper.jar) seem to do just what I need based on my tests.
Can I use these classes for this purpose in my application? Is repackaging allowed?
Does Oracle have any plans for releasing this sort of functionality separately e.g. as part of the Instant Client?

Executing jar from java code, then kill parent java code

Please suggest if there is any best way around on executing jar from java code then killing parent java code.
a) I have desktop based java application say "Monitor.java" which runs every 5 minutes.
b) How can I START external java application say "execute.jar" from Monitor.java THEN EXIT Monitor.java
I tried various options using "ProcessBuilder" and calling bat file but I need Monitor (parent application to EXIT, immediately after calling child (execute.jar)
Try1) ProcessBuilder builder = new ProcessBuilder("java -jar execute.jar");
Process process = builder.start();
Try2) Runtime r = Runtime.getRuntime();
Process p = null;
p = r.exec(new String[] { "cmd", "/c", "start C:/temp/Test.bat" });
