Basically, i need to call a function in perl script from JSP in order to encrypt my information.

Thanks in advance.

I haven't done this myself, but it seems like it is possible in Tomcat.
You can configure Tomcat to handle .cgi calls (it does this via a CGI servlet)
http://www.ftponline.com/javapro/2003_03/online/perl_teden_03_18_03/
http://tomcat.apache.org/tomcat-5.0-doc/cgi-howto.html
Once this is set up, theoretically you should be able to then use requestdispatcher and forward/include a cgi script to invoke the perl.
I don't know if you are using Tomcat or not though... :-)

Executing a shell script from a jsp page

Hi,
I'm facing a problem while executing a shell script from a jsp page.
I'm using Runtime.exec() function.
It's working fine for single statement scripts.But if the script consists of any database processing and some other processing statements,it's not returning the correct exit status of the process.
Will u please help me in this.
If there is any other ways to execute a shell script from a jsp page other than Runtime.exec() like RMI etc,.If so let me know.
Thanks in advance.

Hello,
It's hard to help you but what you can do is listening to the outputs of your script, you should read the output stream and error stream and send them to the default console.
Check this excellent article : http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html?page=4

Call a shell script using OA framework page.

Dear all,
I am new to OA Framework.There is a requirement in which I have to call a shell script using a Web page using OA framework.Can anyone throw light on how can we do this?
Regards

Hi,
You can call shell script from Java and hence from OAF, following is a piece of code
try
String execString = "ls -all"
Runtime r t = Runtime.getRuntime();
Process proc = rt.exec(execString);
/* handle you process from here..
outputstreams, inputStreams and such
catch (Exception e)
e.printStackTrace()
I also don't know Java much but to run shell script you need an object runtime class, I searched it on goolge for you.

Calling a Perl script from a BSP application

Hi all,
       Is it possible to call a Perl program that resides on a different server from a BSP application. If so, how do I do it.
Thanks,
Shiraz.

If I understand correctly what the script does then when you type the script by itself into the webbrowser do you get a response? If it works that way then you can quite easily use something like this:
      <htmlb:gridLayout columnSize = "1"
                        rowSize    = "1"
                        height     = "600"
                        width      = "100%" >
        <htmlb:gridLayoutCell columnIndex = "1"
                              rowIndex    = "1" >
          <phtmlb:matrix width = "100%"
                         height = "100%" >
            <phtmlb:matrixCell col = "1"
                               row = "1" />
            <iframe id="MyIFrame" src="<%= lv_url %>" border="0" width="100%" height="100%" frameborder="0" />
          </phtmlb:matrix>
        </htmlb:gridLayoutCell>
      </htmlb:gridLayout>
See: is it possible to define xhtml:tabscript width by using %
Just give your perl script as the URL for the iframe. Again this only works if calling the perl script in the browser works.

Calling function from Backing Bean or JSP page

We are on Jdeveloper 10.1.3.3.0, ADF Faces, JSF Faces .., Currently there is a function call from Javascript event (onmouseover) in the JSP page. I want to call this function from a backing bean or JSP page, as I have to pass some values to this function.
For Ex., I have a function call like return submit('A','B','Test'); on the Javascript event (onmouseover) in jsp page. I want to remove this function from the javascript event and call from backing bean or jsp page to pass some values into the submit() function. I appreciate if anyone can give some example of how to call this function from backing bean or jsp page in the <SCRIPT> or <SCRIPTLET>
Thanks,
Ram

A use case would be helpful so that we can get a better idea of what you want to do.
As a general rule, there is no way to call a client side Javascript function from a backing bean, which is server side. However, there are ways to inject information from a backing bean into your Javascript call. For instance, I have an application that uses Google Maps API. It has an onload call to a Javascript function that builds the map and designates it's center point. The center point comes from a backing bean as latitude and longitude properties. So here is my body tag:
<afh:body onload="initialize(#{backing_searchResults.latitude},#{backing_searchResults.longitude},#{searchCriteria.distance})"
onunload="GUnload()">onload calls the Javascript function called initialize, and passes the latitude, longitude, and distance from the bean. Is the function really being called from my backing bean? No - the parameters are hard coded into the onload event code when the page is rendered. Does it do the job? Sure it does.

Calling a perl script from stored procedure

Can anyone tell me how to call/run a perl script from a stored procedure? If you have a sample code, please include it.
Thanks in advance

If you have a web server setup that runs perl, you can do this by using the utl_http package...Here is some code I use to run a perl script and print the results to a web page on our site.
The in_URL parameter is the address of the perl code(i.e. http://website/path/perlscript?param1=value1&param2=value2 etc)
PROCEDURE call_perl(in_URL VARCHAR2) IS
/* This is setup to allow a perl program to be submitted as a batch program
using the standard Portal batch program.
Sometimes these jobs take a long time to run, so the timeout value must
be set to a large value. The default timeout is 60 seconds, which is not long enough. */
req utl_http.req;
resp utl_http.resp;
value VARCHAR2(1024);
BEGIN
req := utl_http.begin_request(replace(utl_url.escape(replace(in_URL,'%3A',':')),CHR(13)));
utl_http.set_transfer_timeout(req, 18000); -- Set timeout to 5 hours for this specific request.
resp := utl_http.get_response(req);
LOOP
utl_http.read_line(resp, value, TRUE);
htp.p(value);
END LOOP;
utl_http.end_response(resp);
EXCEPTION WHEN utl_http.end_of_body THEN
utl_http.end_response(resp);
WHEN utl_http.init_failed THEN
htp.p('INIT FAILED');
WHEN utl_http.request_failed THEN
htp.p('REQUEST FAILED');
htp.p(NVL(utl_http.get_detailed_sqlerrm,' No more detail available.'));
END;
If you don't have a web server setup, I don't know offhand how you could do this.

How do I call a 10g report from a jsp page securly?

How can I call a report from a jsp page securly? We are migrating from 10g forms to J2EE, and we want to keep using our reports. In forms we were able to do this using a cookie. How can I pass a users credentials to reports without the user having to connect to the database? Single Sign-on isn't an option either.
Thanks,
Jim

Hi Jim,
If you want to pass the user credentials to the report dynamically, then SSO (Single Sign-On) is the only option I can think of.
If the user credentials can be hard-coded, then the following 2 solutions are possible:
1. Use cgicmd.dat file, and write the user credentials in the file.
2. In your report JSP itself, you could write the following:
<rw:report id="report" parameters="userid=scott/tiger@mydb">

Repeater fails using {container.item} context within included JSP pages

Greetings,
I'm using Bea Workshop 8.1.2 and netui's based framework.
I'm experiencing a problem relating to the use of jsp:insert tags as a way of templating the code as to make it more maintainable and cost effective.
The problem arises when using repeaters and then binding a <netui> tag with a "container.item" context inside the included jsp page.
Example:
On a PageController we define on its scope a rather simple data structure:
public String[] array={"Item1","Item2","Item3"}
The associated index is as follows:
index.jsp
<netui:html>
<netui-data:repeater dataSource="{pageFlow.array}">
<netui-data:repeaterHeader></netui-data:repeaterHeader>
<netui-data:repeaterItem>
<netui:label value="{container.item}"/><br>
</netui-data:repeaterItem>
<netui-data:repeaterFooter></netui-data:repeaterFooter>
</netui-data:repeater>
</netui:html>
This works as expected, it prints the data in the array list. Fine.
Now, with the <jsp:insert> tag usage, we get two files index.jsp and body.jsp:
index.html
<netui:html>
<netui-data:repeater dataSource="{pageFlow.array}">
<netui-data:repeaterHeader></netui-data:repeaterHeader>
<netui-data:repeaterItem>
<jsp:include page="body.jsp" flush="true"/>
</netui-data:repeaterItem>
<netui-data:repeaterFooter></netui-data:repeaterFooter>
</netui-data:repeater>
</netui:html>
body.jsp
<netui:html>
<netui:label value="{container.item}"/>
<netui:label value="{pageFlow.array[0]}"/>
</netui:html>
With this example the {container.item} tag fails with this exception:
"Caught exception when evaluating expression "{container.item}" with available binding contexts [actionForm, pageFlow, globalApp, request, session, appication, pageContext, bundle, container, url, pageInput]. Root cause: com.bea.wlw.netui.script.xscript.IllegalContextStateException: The Tag "com.bea.wlw.netui.tags.html.Label@cb5dce" does not have a valid parent of type DataAccessProvider. The expression "container["item"]" requires a parent of this type."
BUT - and here is my problem with this - the label tag with {pageFlow.array[0]} PRINTS THE DESIRED ELEMENT.
Also, on an extended example with a <form> tag around the main index html and the array structure inside a FormData class, {actionForm.array[0]} ALSO PRINTS THE DESIRED ELEMENT.
Only {container.item} gloriously fails with an exception complaining about IllegalContextStateException.
This is a total nonorthogonal behaviour, the features do not work as expected and indeed, with the importance of repeaters for netui's development, this preclude us from the minimum standard for structured web application design.
Does anyone have any clue about this behaviour? If not a fix, at least an explanation...
Thanks in advance.

I am trying to insert multiple rows I when submited I am get ting only 1 row in the DatabaseForm.
my netui.log file shows this error:

How to call an exe program from the JSP page?

How to call and display the interface from a exe (residing on C: drive) on my JSP page. Our customers supplied us with an exe file and they want this to be incorporated on the JSP page that has other components also, like forms, etc. The interface of the program has to be displayed in specific co-ordinates on the JSP page. Any help is highly appreciated. Thanks in advance.

Can't be done with JSP.
JSP runs java on the SERVER only.
All that gets to client is an HTML page. So all that
you can do at the client is what an HTML page can do.
Obviously that doesn't include running a file on the
client machine.
Take a look into Applets, or maybe ActiveX controls.Thanks for the reply.
Any idea on how to use the ActiveX controls in this regard?
