Beginner question: support to HTTP POST om Oracle AS

Hi!
I don't know if this is a suitable forum but since i use JDeveloper and Oracle BPEL I'll try my luck here :).
I have a Java web application built in JDeveloper and a couple of BPEL processes.
In these processes I use Java embedding (a piece of Java code) that opens a connection to a given URL and post a XML message to this URL. I didn't have much problems creating these processes.
Now I have to provide a support to HTTP POST on my side. Since web application and services development are quite new to me I hope someone can point me the right way to do this. The requirements I have are: I can have a single URL to which the http POSTs will be issued.
If I understand correctly I cant use a web service since I have to enable different types of XML posts. What are my options? Can I create some kind of listener for http POSTs? Can I create a jspx that will 'wait' for http posts and than call some of mine BPEL processes? Is there a way to create a BPEL process that 'waits' for http POSTs? Are there other options.
I'd really appreciate any pointers on this.
Regards,
BB.

Frank,
I've tried creating a Servlet listener that implements HttpSessionListener interface. Now I have two methods, sessionCreated and sessionDestroyed but I don't know where to go next. I can't find any documentation on this issue yet.
Should I create a jspx page with form node that has method attribute set to POST or maybe I don't even need a web page? I already have a login page that has a form with method set to POSt, will this pose any kind of troubles for me?
I apologize for any stupid questions but as I said I have no experience in doing this and las couple of days I'm searching and reading different documentation on this topic so any more pointers would be appreciated.

Initiating an HTTPS post via Oracle Forms 6i

Greetings all...
Here is my problem. I would love some advise/next steps on solving it.
We are currently using web-version of Forms 6i with the JInitiator 1.1.8.16. I have a new requirement for an existing form where it needs to initiate an HTTPS "post" (not "get") to a remote server and then receive a response of success or not and some other information that the form will then act upon. I believe this means I cannot simply use the "web.show_document" built-in because it uses the "get" method rather than the "post" method.
Although I am a veteran Forms developer, I am new to all this java stuff. It has been recommended to me that I incorportate a JavaBean into the form to call on this remote service, but I have no idea what that means -- I've never opened JDeveloper. It was also mentioned that maybe there is already a JavaBean in existence that I can just use. I don't know what details of my situation would be useful to know to determine if one exists or not. Does this possibly existing JavaBean need to know already which URL I want to go to? Will it need to know the exact parameters I want to pass or could there be a JavaBean out there to simply "call any URL using the post method" regardless of the number of parameters to send it?
I've looked through some of the forum for this question and since I'm clueless on java stuff, I didn't find anything that jumped out as an answer for me. Can someone (or many of you would be fine) clue me on the best approach? Thanx.
Shane.

Since the initial post above, I've discovered more to this situation that doesn't give me much hope of implementation.
The "response" that I get back from the remove service is simply a "redirect" telling the initiating browser to go to a URL that I have to set up. When the response comes back, the remote service will tell the browser to go to this redirected URL with the "responses" as parameters in the URL resulting in the user's browser calling this "redirect" URL with a "get" method.
Not sure what all that means to be honest, but am wanting to learn.

Submitting a PDF form via HTTP Post: Beginner's Questions

Hi,
I am completely new to PDF forms, so I have been finding the documentation and options overwhelming.
I am hoping to get pointed to the documentation/tutorials/examples I really need.
I would like to build a "proof of concept" for my boss. I would like to include a screen in our Java ( JSP & Spring ) webapp where either a PDF form is embedded or is accessed via a link.
I have
Adobe Acrobat Distiller X standard license
Adobe Acrobat X Standard
Microsoft Office 2010
I made a small, 3 field Microsoft Word form. I then converted it via DIstiller into a PDF form.
I then found this document about how to submit a PDF form to a server side component:
http://acrobatusers.com/tutorials/form-submit-e-mail-demystified
My big problem with this document it doesn't have an example nor an example showing what is going on in a full HTML page. As I result I have some questions:
Can I see such an example somewhere?
Does the call to the javascript function doc.SubmitForm(urlToMyServerSideComponent) go in a script tag on the HTML page like other javascripts?
Can I execute that submit function from an HTML button or do I need to put a "submit" button on the PDF form?
Do I need Adobe LiveCycle in order to create a PDF form with a "submit" button? Free versions?
Can I send via HTTP POST ?
Do I need Adobe LiveCycle to crate a PDF form with a digital signature?
Is there a document/tutorial that fits where I am starting off from? ( Please no books, I am tyring to show my boss that this is something that can be done, in a reasonable amount of time, not time to get and go through a book ).
Thanks in advance for any tips that get me pointed in the right direction
Steve

To answer some of your specific questions:
2, 3. The submit form button needs to be on the PDF. You can either configure a Submit Form action or use the submitForm JavaScript method.
4, 6: No to both questions. You can create the form in Acrobat. Such forms are knows as Acroforms, as opposed to XFA forms that are created with LiveCycle Designer. Acroforms have wider support.
5: Yes, that's the method that's used when submitting to a web server. You have your choice of formats. The "HTML Form" option causes the form data to be submitted in the same format as an HTML form, so the same type of server-side code can be used to process the data. As Dave's tutorial shows, the server should return an FDF as the response, however, as opposed to HTML content.
It's a mistake to try to embed the PDF in a web page. So much depends on the user's browser, PDF viewer, and how both are configured. PDF forms can be submitted directly from Adobe Reader/Acrobat, so it's not necessary for them to be viewed in a browser. Note that Adobe Reader for iOS/Android don't yet support submitting to a web server (apart from FormsCentral), but that's is supposedly being worked on.
Since you mentioned digital signatures, be aware that for Reader users to be able to sign, the document has to be Reader-enabled, either with Acrobat Pro or LiveCycle Reader Extensions (which is not the same as LiveCycle Designer). Digital signatures in PDF forms are not yet supported on mobile devices. Also, you will want to submit the entire PDF, as opposed to just the form data, when submitting a digitally signed form.

HTTP post data from the Oracle database to another web server

Hi ,
I have searched the forum and the net on this. And yes I have followed the links
http://awads.net/wp/2005/11/30/http-post-from-inside-oracle/
http://manib.wordpress.com/2007/12/03/utl_http/
and Eddie Awad's Blog on the same topic. I was successful in calling the servlet but I keep getting errors.
I am using Oracle 10 g and My servlet is part of a ADF BC JSF application.
My requirement is that I have blob table in another DB and our Oracle Forms application based on another DB has to view the documents . Viewing blobs over dblinks is not possible. So Option 1 is to call a procedure passing the doc_blob_id parameter and call the web server passing the parameters.
The errors I am getting is:
First the parameters passed returned null. and
2. Since my servlet directly downloads the document on the response outputStream, gives this error.
'com.evermind.server.http.HttpIOException: An established connection was aborted by the software in your host machine'
Any help please. I am running out of time.
Thanks

My requirement is that I have blob table in another DB and our Oracle Forms application based on another DB has to view the documents . Viewing blobs over dblinks is not possible. Incorrect. You can use remote LOBs via a database link. However, you cannot use a local LOB variable (called a LOB <i>locator</i>) to reference a remote LOB. A LOB variable/locator is a pointer - that pointer cannot reference a LOB that resides on a remote server. So simply do not use a LOB variable locally as it cannot reference a remote LOB.
Instead provide a remote interface that can deal with that LOB remotely, dereference that pointer on the remote system, and pass the actual contents being pointed at, to the local database.
The following demonstrates the basic approach. How one designs and implements the actual remote interface, need to be decided taking existing requirements into consideration. I simply used a very basic wrapper function.

SQL> The concern is the size of the LOB. It does not always make sense to access the entire LOB in the database. What if that LOB is a 100GB in size? Irrespective of how you do it, selecting that LOB column from that table will require a 100GB of data to be transferred from the database to your client.
So you need to decide WHY you want the LOB on the client (which will be the local PL/SQL code in case of dealing with a LOB on a remote database)? Do you need the entire LOB? Do you need a specific piece from it? Do you need the database to first parse that LOB into a more structured data struct and then pass specific information from that struct to you? Etc.
The bottom line however is that you can use remote LOBs. Simply that you cannot use a local pointer variable to point and dereference a remote LOB.

Can any one provide an web service technique that supports http post...?

hi,
i'm working with servlets. i need a webservice technique that supports http-post.
is it possible to work http-post using servlet & axis2 webservice....?

hi, if you are about to use axis2, consider trying JAXWS since its very fast to startup, it will then take care of everything what is beyond your business objects (so transforming in into XML etc) moreover, you're going to use web services, thus you ll be working with SOAP, which will wrap your business representation...
here a sample for a time -service. The Date object will automatically be trasinformed into appropriate xsd type by the axis2 engine
@WebService
public class Clock {
public Date getCurrentTime(){
return new Date();
}

Invokation of Oracle J2eeWeb Services using HTTP POST

I have created Oracle J2ee web service from a Java Class in Oracle Jdeveoper 10g. I want to invoke web methods in the web service using HTTP POST method. Currently, these web methods can be invoked using HTTP GET method which is the default option. Please suggest any solution for this.
bye

Vivek,
If you want to make a call to Web Services from .NET, you have to generate a client proxy in your language of choice: C#, VB.NET, J#, ...
There are two ways of doing so. a) from the command line using a tool named WSDL.EXE. b) from Visual Studio 2003 using the 'Add Web Reference' command.
In either case, you will have to point to the WSDL of your service to generate the client proxy. The URL for the WSDL is the same as the URL for the service, with the ?WSDL parameter.
Hope this helps,
Eric

HTTP POST/1.0 support

Hello,We have found that WLS6 does not accept "HTTP POST/1.0" header. All data posted under that header becomes "null", as if they were never posted.We then modified the header to read "HTTP POST/1.1" and then WLS6 accepts the posted data fine. We tried the same test with Tomcat and was able to post under both versions. One would think that WLS6 should be backward compatible, so that it should accept both POST/1.0 and 1.1. Is there a work around for this? Did anyone ever experiance the same problem? or am I missing something?Thanks,Cheng


I have a servlet that receives POSTs from both 1.0 and 1.1 I capture the
          output of getProtocol of the request stream and I haven't noticed any
          problems.
          Thanks

Oracle AS 10gR2: create new oc4j instance supporting ssl/https

hi,
i've got an oracle application server 10.1.2 (infra and midtier).
in the midtier i want to add a new oc4j-instance which is possible via oracle enterprise manager 10g. after i've created the new oc4j-instance and deployed a war-file ("myapp") i can access a jsp of the deployed application with "http://myserver/myapp/test.jsp". now i want to enable ssl/https for my new oc4j-instance.
i did the following steps according to the manual (http://download-west.oracle.com/docs/cd/B14099_19/web.1012/b14013/configssl.htm):
1) created certificate with keytool
2) added secure-web-site.xml (new oc4j-instance)
3) modified sever.xml (new oc4j-instance)
4) restarted new oc4j-instance
my test.jsp is still available with "http://myserver/myapp/test.jsp", but when i try to access it with "https://myserver/myapp/test.jsp" i get an error that the resource is not found. strange that when accessing test.jsp with http it is searched in the folder of my new oc4j-instance (%ORACLE_HOME%/j2ee/oc4jnew/...), but when i want to access the page through https the server looks for the jsp in the default oc4j "home" (%ORACLE_HOME%/j2ee/home/...).
what's the reason for that an how can i correct it?
regards,
matthias
Edited by: matthias on Apr 26, 2010 4:15 PM

You need to secure the HTTP Server and not the OC4J, remember that HTTP and WebCache are your frontends for any presentation layer, you need to modify ssl.conf and webcache in WebCache Admin page (in EM Console) to make them use ssl ports, as well as you want to use url with no port, you need to use port 443.

Uploading big files via http post to XDB table

Hello,
I ve created a web form for to upload files as blobs to the database using XML DB, DBPS_EPG package and preconfigured DAD.
The issue is that small files (~10kb) are being uploaded ok, but file which is 100K during http post returns connection reset from the server side.
To my opinion there might be some max file size parameter for oracle server to accept during oracle listener tcp connection (as apach has maxrequestlimit).
Is there any workaround for to load large files to the XDB table via webform?

Welcome to Apple Discussions!
Much of what is available on Bittorrent is not legal, beta, or improperly labelled versions. If you want public domain software, see my FAQ*:
http://www.macmaps.com/macosxnative.html#NATIVE
for search engines of legitimate public domain sites.
http://www.rbrowser.com/ has a light mode that supports binary without SSH security.
http://rsug.itd.umich.edu/software/fugu/ has ssh secure FTP.
Both I find are quick and a lot more reliable than Fetch. I know Fetch used to be the staple FTP program, but it grew too big for my use.

HTTP POST binding not available in 11g???

Hi,
I am trying to call a HTTP service using HTTP POST, passing HTTP params to it. I created a small bpel process in 10.1.3.4, and used the HTTP POST samples, which worked out really well.
However target platform is 11g. So I just tried to migrate the project and got the following warnings.
WARNUNG: UPGBPEL-02043: The WSDL used for "HTTPPostParam" has HTTP based binding definition for the porttype specified. SOA Suite 11g does not support this and hence upgrade will not carry this over to the generated composite. Compilation will fail if the composite reference is not setup with binding. After upgrade, setup the reference by specifying a WSDL with SOAP binding. Check SOA Upgrade guide for more information.
WARNUNG: UPGBPEL-02009: No Binding setup for : "HTTPPostParam". This will cause compilation of the upgraded project to fail. Check SOA Upgrade documentation on manual steps necessary to bind this composite reference. If necessary, upgrade and deploy any dependencies. If planning to retain 1013x nodes in this projects dependency tree, check earlier part of this log for 1013x WSDL URLs that can be used.
Does this really tell me that HTTP post or get is not available anymore? Or do I miss anything? Or is there a workaround?
Thanks and regards,
Thomas

The sample that heidi posted above is basically the codebase to the http binding we are planning to ship with Patchset 2. It's based on Jax-WS' http binding.
Let me know if you run into any issues (the source is included - so you can play around :) - no license )

Http_utl.text_write for http 'POST" does not work

i have a proc that uses utl_http code I have seen all over on web sites for 'POST'ing to a REST web service ..... i use utl_http.write_text to write data to the request body but no data gets written ...... below are the code segments I use
url entered directly into browser that **works fine**: http://www.media.com/admintool/Services.aspx?par_string=[{ "PAR_Transaction_Id" : 5566338, "MRI_Title_Name" : "4 Wheel & Off Road"}]
calling routine:
declare
l_url varchar2 (300) := 'http://www.media.com/admintool/Services.aspx';
l_data clob;
l_query varchar2(32767);
begin
dbms_output.enable(3000000);
l_data := '[{
"PAR_Transaction_Id" : 5566338,
"MRI_Title_Name" : "4 Wheel & Off Road"}]
http_util_pkg.http_post(
p_url_in => l_url, p_data_in => l_data);
end;
called routine segment:
l_http_req := utl_http.begin_request (p_url_in, 'POST');
-- Set the HTTP request headers
utl_http.set_header(l_http_req, 'User-Agent', 'Mozilla/4.0');
utl_http.set_header(l_http_req, 'content-type', p_data_type);
utl_http.set_header(l_http_req, 'content-length', v_length);
-- Write the data to the body of the HTTP request
utl_http.write_text(l_http_req, 'par_string=');
while v_index <= v_length
loop
utl_http.write_text(l_http_req, substr(p_data_in, v_index, 4000));
dbms_output.put_line ('data = ' || substr(p_data_in, v_index, 4000));
v_index := v_index + 4000;
end loop;
results .... you can see below that the header content length is non-zero but the response header says there is no content, so something is haywire with the write_text method
url = http://www.media.com/admintool/Services.aspx
length in data = 1271
http package; url = http://www.media.com/admintool/Services.aspx
after set authentication
after write headers
data = [{
"PAR_Transaction_Id" : 5566338,
"MRI_Title_Name" : "4 Wheel & Off Road"}]
after write text
status code: 200
reason phrase: OK
Connection: close

Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET

Cache-Control: private
Content-Length: 0 *************** response header says no content !!!
can you help me figure out what is wrong with the utl_http.write_text method ???
thank you

Please do not resurrect old threads - rather ask your question in a new thread. If need be, add a URL in your new thread posting that refers to the old thread. Also add as much relevant details as possible. Your Oracle version (all 4 digits). Your o/s. If possible, sample code and data that can be used as a test case. Complete error details. And what the intent of the code is (i.e. what the actual problem is that you're trying to solve).
As for HTTP post - works just fine as far as I've used it.

Simple HTTP Post Handler - Best Practice?

I would like to create a fairly simple ASP.Net application that takes an XML record from an HTTP post request, submits it to a process that invokes a command line app that parses the XML file, takes the parsed XML file (as XML), and returns the result.
For now the process can be synchronous as the transform has to complete and there are no parallel activities that need to be performed.
I'm not sure that writing an HTTP Handler is the way to go, but maybe I'm mistaken. Plus there are no examples of doing that in Visual Studio 2013 using IIS 8.0 or 8.5 and I don't really understand the value of applying a file extension or processing
an HTTP post to initiate the request, perhaps using a dedicated port. I already have a class library for handling the process request.
I'm also a little confused about reading the post request - it seems I can just do it during the page load and that I should be able to extract the first request form field - that of course means using a webform to process the request which seems to be the
most straight-forward way to do this. So I'm looking for the best practice for fielding this kind of request. My target server is Windows 2012, but I'm developing with VS 2013 and C# on Windows 7 using IIS Express and configuring IIS is confusing.
Overall it is a fairly simple app, but there are so many rich new features in VS 2013 (most of my work has been in VS 2005). I also want to build a test app and am looking for the best way to do so, although I think I can build a simple client app
to do that. The business requirements will be to issue the post request from a MarkLogic xquery request which will take care of any JSON wrappers and balance between multiple Windows servers to handle the load.
Thanks for any help with this!

Hi Tim,
Thank you for posting in the MSDN forum.
Actually this forum is to discuss the VS IDE, if this issue is related to web development, you could ask this question in the ASP.NET forum:
http://forums.asp.net. If then, you could get an answer more quickly and professional. Thanks for your cooperation.

HTTP POST timeout on specific button

Hi,
I'm trying to work out if Oracle ADF supports a POST timeout that is configurable for an action in the UI. The use case is as follows:
1. A specific button in the front end is clicked on by the user, causing a HTTP POST (This then causes an action in the backend, that takes an indeterminate amount of time to return)
2. A timeout should occur after a configurable duration (Obvious technical caveats apply, such as this value not being able to exceed the JTA transaction timeout)
3. The user should be redirected to a error page specific to this type of timeout.
I would like to configure this specific button to have a lower timeout than both the "Post Timeout" in the WebLogic server Admin console configuration for the HTTP Protocols. There are other transaction timeouts in place that will clean up the services layer and any database connections to protect the servers from these running indefinitely.
Thanks in advance.

Frank,
Many thanks for the swift response. I'll have a look into other ways of tackling this in the Java layer of the application.

Http post with bpel

I am not sure if this forum is the right forum for my question but I post anyway to see if anyone can help
me. I have created a very simple bpel using http post; all it does is to copy the input to the output.
The output from my bpel looks like this:
<myContact xmlns="http://xml.netbeans.org/schema/XmlPost">
<ns0:LastName xmlns:ns0="http://xml.netbeans.org/schema/XmlPost" />
<ns0:FirstName xmlns:ns0="http://xml.netbeans.org/schema/XmlPost" />
<ns0:EmailAddress xmlns:ns0="http://xml.netbeans.org/schema/XmlPost">
LastName=aa&FirstName=bb&EmailAddress=cc&OfficeAddress=dd</ns0:EmailAddress>
<ns0:OfficeAddress xmlns:ns0="http://xml.netbeans.org/schema/XmlPost" />
</myContact>
My question is why the EmailAddress element contains all my input data. I should expect the lastname element
has 'aa', the firstname element has 'bb', the emailAddress has 'cc' and the officeAddress has 'dd'.
Can someone please tell me what I do wrong in here.
Thanks,

sure you send the right xml?
what I would try is to copy the xml from the receive, paste and extend it, and see if this works . . these errors are mostly because of no namespace defined or such ..
sure your element has the right namespace?
hth clemens
2)
here is the xml for the following schema ..
XML
<ns1:AttributetestProcessRequest xmlns:ns1="http://xmlns.oracle.com/Attributetest">
<ns1:input/>
</ns1:AttributetestProcessRequest>
schema
schema attributeFormDefault="unqualified"
     elementFormDefault="qualified"
     targetNamespace="http://xmlns.oracle.com/Attributetest"
     xmlns="http://www.w3.org/2001/XMLSchema">
     <element name="AttributetestProcessRequest">
          <complexType>
               <sequence>
                    <element name="input" type="string"/>
               </sequence>
<attribute name="service" use="required" type="string"/>
          </complexType>
     </element>
     <element name="AttributetestProcessResponse">

               </sequence>
          </complexType>
     </element>
</schema>
it works design and runtime in 10.1.3.1
