Execute Javascript from our JAVA code

Hi all,
I have a question:
It's possible to execute a javascript code from the back bean page. For example , we execute a button action (Conect to a db, insert data) and if all it's ok we execute a simple alert ("The insert is ok!!");
Any way to do this??
Thx!

I don't know enough about Javascript, but I don't think it can be executed from within Java code.
If you can't, an alternative is to provide a status code and/or status message that is accessible to the page. There are a number of ways to do this. One option is to put the information in a hidden field. Another option is to put the information in a session bean and add appropriate JSP code to your page to get that information.
You can link a Javascript function to the page's onLoad event. The function can get the status code/status message and create the alert.

Execute PL/SQL block with named binds from within java code?

Hi guys,
Is there any good way to execute my PL/SQL code, for example
BEGIN         :x := :x+1; END;
from my Java code? I need nothing complicated, just static code block with named binds.
I have tried the Oracle exetnded JDBC (setXXXbyName methods):
public static void main(String[] args){     try {     Class.forName("oracle.jdbc.driver.OracleConnection");     Connection conn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","user","password"); String SQL="begin :x:=:x+1; end;"; OracleCallableStatement stmt; stmt=(OracleCallableStatement)conn.prepareCall(SQL); stmt.setIntAtName("x", 5); stmt.registerOutParameter("x", Types.INTEGER); stmt.execute(); System.out.println(stmt.getInt("x"));     } catch (Exception x) { x.printStackTrace();    }   }
And get the java.sql.SQLException: operation not allowed: Ordinal binding and Named binding cannot be combined!
Then i've tried SQLJ appoach:
public static void main(String[] args){     try {     Class.forName("oracle.jdbc.driver.OracleConnection");     Connection conn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","user","password");       Oracle.connect(conn);       System.out.println("Connected!");           int x=3;       #sql { BEGIN         :x := :x+1;       END; };           System.out.println("x=" + x);     } catch (Exception x) { x.printStackTrace();    }   }
And x=3 had retuned... Although 4 expected.
Then, I've set parameter sqlj.bind-by-identifier=true
And result is another exception! java.sql.SQLException: Missing IN or OUT parameter at index:: 2
Can you please mark my mistakes/point to correct solution?
Thanks in advance,
Alexey

[Best practice] How to call a service from custom Java code

Hi all,
I'm wondering what the best method is to call a standard service from custom Java code?
In a specific situation iDoc script is extended with custom functions with a custom component. There's Java code mapping to these functions that is executing these functions. The iDoc script functions are called from a workflow entry script.
In the Java code that runs when the custom iDoc functions are called, I want to call a standard Content Server service. I don't think that the m_service variable is available, so filling the binder and using m_service.executeService() probably isn't possible.
Also, if it were possible (that is, if I want to call a standard service from my own custom service Java code), what would then be the best method to do so?
Regards, Stijn

Hi Sapan,
Let me explain a bit further.
I'm an UCM consultant trying to solve a problem that occured at a client when they installed the CS10gR35CoreUpdateBundle.
Content items are entered into a Workflow when they are checked in. Part of one of the entry scripts of the a workflow step is that related content to the content item in the workflow is (re)submitted for conversion.
To achive this, a custom component provides an iDoc script extension. This iDoc function (resubmitForConversion) is implemented in Java (the class extends ScriptExtensionsAdaptor).
In this Java method, first the related content items are fetched. Then the service RESUBMIT_FOR_CONVERSION should be called for all dID's in of the related content.
Thus, at a certain point in the custom Java code, a native Content Server service must be called. Of course the class of this Java code does not extend the Service class, so the m_service object isn't available.
The thing is: before installed the 10gR35CoreUpdateBundle everything worked OK. This code was used to execute the service:
        Workspace workspace = CommonUtils.getSystemWorkspace();
        String cmd = binder.getLocal("IdcService");
        if (cmd == null) throw new DataException("!csIdcServiceMissing");
        ServiceData serviceData = ServiceManager.getFullService(cmd);
        if (serviceData == null) throw new DataException(LocaleUtils.encodeMessage("!csNoServiceDefined", null, cmd));
        Service service = ServiceManager.createService(serviceData.m_classID, workspace, null, binder, serviceData);
        UserData fullUserData = CommonUtils.getFullUserData(userName, service);
        service.setUserData(fullUserData);
        binder.m_environment.put("REMOTE_USER", userName);
        ServiceException error = null;
        try {
            service.setSendFlags(true, true);
            service.initDelegatedObjects();
            service.globalSecurityCheck();
            service.preActions();
            service.doActions();
            service.postActions();
            service.updateSubjectInformation(true);
            service.updateTopicInformation(binder);
        } catch (ServiceException e) {
            error = e;
        } finally {
            service.cleanUp(true);
            if (!CommonUtils.isWorkspaceConnectionInTransaction(workspace)) {
                 workspace.releaseConnection();
        }the first problem was that the CS began to complain that a transaction was started within another transaction. So I suspect that the 10gR35 update wrapped a transaction around a workflow script entry.
With some decompiling I figured out how a service is called from iDoc with the <$executeService()$> command. So I replaced the code above with:
              String cmd = binder.getLocal("IdcService");
            ServiceData serviceData = ServiceManager.getFullService(cmd);
            if (serviceData == null) throw new DataException(LocaleUtils.encodeMessage("!csNoServiceDefined", null, cmd));
            Workspace workspace = CommonUtils.getSystemWorkspace();
            Service service = ServiceManager.createService(serviceData.m_classID, workspace, null, binder, serviceData);
            UserData fullUserData = CommonUtils.getFullUserData(userName, service);
            service.setUserData(fullUserData);
            binder.m_environment.put("REMOTE_USER", userName);
            service.initDelegatedObjects();
            service.executeSafeServiceInNewContext(cmd, true);This solved the transaction problem but introduces another problem: !csUnableToResubmitItem,(null)!csIllegalScriptAccess,RESUBMIT_FOR_CONVERSION
The Service Reference Guide says that the access level for RESUBMIT_FOR_CONVERION is 33 (Read, Scriptable). However, in shared/config/resources/std_services.htm the access level is specified as 2 (write).
Thus, my question still is:
What is the best method to call a standard Content Server service from any Java code (so without extending the Service class, or having the m_service object available)?

Runnig DOS commands from the java code?

Hi reader,
how can I execute DOS commands (I am on an Windows XP Machine) from my java code and also capture the output?
I think the
runtime.exec(command)
only executes win32 processes.
Please suggest
TIA
Ayusman

Again, this link should tell you most of what you need to know:
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
You're not limited to the Win32 platform unless you're using specific DOS commands. Perhaps if you're just after file system information then some of the classes in the java.io package can help.
If it's not enough, perhaps a resource bundle or something similar can provide you with the names of the external programs you need to run, i.e. "dir" for win and "ls" for *nix.

How do I pass an error status from my java code back to the Program Job Ser

How do I pass an error status from my java code back to the Program Job Server?
I have a jar program object that reports a scheduled status of "Success" even if the java code errors out.

Exceptions thrown from the program object are ignored by the program job server.
You need to configure the Program Object, then stream out a special string sequence to the stdout of the Program Object, to set the scheduled instance status to Failed.
Look up SAP KBase 1201804 - How to programmatically set the status of a Program object to "Failed"

Using a Java Program to execute JavaScript from a website

Okay, let me try and explain as good as I can. I have a program now, that searched through all files and folders in Unix (Solaris machine) and gets the list of files in the bin and sbin folders.
Well, I want to find the version of each of these files from the bin and sbin folders and not all of them have the -v, -V or -version feature (or any others there may be). But, I found this page:
http://sunsolve.sun.com/pub-cgi/fileFingerprints.pl
where if you go to the page I can find an md5 number, place it in the box and click submit to find versions, if available.
My thing is, as I find the number from my java program, I want to be able to open this page, insert in the box (or maybe even call the javascript function) and then submit to get the version numbers. That would mean I could need to get back info from the javascript function.
I hope that explains what I need and hope that someone can help me.
I have found information on the JSObject, but not sure what that means exactly so if someone can explain this:
JSObject win = JSObject.getWindow(this);
JSObject doc = (JSObject) win.getMember("document");
JSObject loc = (JSObject) doc.getMember("location");
String s = (String) loc.getMember("href"); // document.location.href
win.call("f", null);
it would be greatly appreciated. But, this may not even be what I need. I see that the win.call is where I would call the function needed and I am guessing the null could be where I put the number if that is how the function i need works like that. But, what I dont understand is what "document" is and "location". Also, i the "href" the page I put above? I am just lost on that. Hope someone will understand.
Thank again for the help!

Exactly so. Check out the last item - reading and writing to a URL - writing to a URL.
Pulling out the form code from that page:
<FORM METHOD="POST" ENCTYPE="application/x-www-form-urlencoded">
<TEXTAREA NAME="md5list" ROWS=16 COLS=66 MAXLENGTH="33792"></TEXTAREA>
<BR><INPUT TYPE="submit" NAME="submit" VALUE="submit">
<INPUT TYPE="reset" VALUE="reset">
</FORM>You should end up with something like this (copying and pasting from the example):
URL url = new URL("http://http://sunsolve.sun.com/pub-cgi/fileFingerprints.pl");
String sNumbers = "put your serial nos in this string"
URLConnection connection = url.openConnection();
connection.setDoOutput(true);
PrintWriter out = new PrintWriter(connection.getOutputStream());
out.println("md5list=" + sNumbers);
out.close();
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null){
// read in the HTML page result for later parsing?
in.close();

How to call a shell script from a java code
