Calling google translate from PLSQL using HTTPURITYPE

Hi All,
I am calling Google Translate URL from a Select query as below. This is to convert from English to Vietnamese.
SELECT REGEXP_SUBSTR(tr,'<span[^>]*>(.*)',1,1,'i',1) translated_value
FROM (SELECT httpuritype('http://translate.google.com/?hl=en&layout=1&eotf=1&sl=en&tl='||'vi'||'&text='|| UTL_URL.escape('My text to be converted')|| '#').getclob() tr
FROM DUAL);
The expected result is: (Checked on google.com/translate from web and in the page source the charset was UTF-8)
Văn bản của tôi được chuyển đổi
What I got it is: (Checked the clob returned by httpuritype and the charset was ISO-8859-1)
Văn bản của tôi được chuyển đổ
Please, any help on getting the expected result
Regards,
Narender

Oracle BI 11.1.1.7.1: Calling BI webservices from Plsql Procedure: ORA-29532: Java call terminated by uncaught Java exception: java.lang.NoClassDefFoundError

Hi,
 I have a requirement of calling BI webservices from Plsql stored procedure. I generated all my wsdl java classes and loaded them into the database. However, when I tried to call one of my java class using stored procedure, it is giving me"ORA-29532: Java call terminated by uncaught Java exception: java.lang.NoClassDefFoundError".
*Cause: A Java exception or error was signaled and could not be
 resolved by the Java code.
*Action: Modify Java code, if this behavior is not intended.
But all my dependency classes are present in database as java class objects and are valid. Can some one help me out of this?

Stiphane,
You can look in USER_ERRORS to see if there's anything more specific reported by the compiler. But, it could also be the case that everything's OK (oddly enough). I loaded the JavaMail API in an 8.1.6 database and also got bytecode verifier errors, but it ran fine. Here are the errors I got when loading Sun's activation.jar, which ended up not being a problem:
ORA-29552: verification warning: at offset 12 of <init> void (java.lang.String, java.lang.String) cannot access class$java$io$InputStream
verifier is replacing bytecode at <init> void (java.lang.String, java.lang.String):12 by a throw at offset 18 of <init> void (java.lang.String, java.lang.String) cannot access class$java$io$InputStream
verifier is replacing bytecode at <init> void (java.lang.String, java.lang.String):18 by a throw at offset 30 of <init> void (java.lang.String, java.lang.String) cannot access class$java$io$InputStream
verifier is replacing bytecode at <init> void (java.lang.String, java.lang.String):30 by a throw
Hope this helps,

Calling java classes from plsql procedures

I'm attempting to call java classes from plsql procedures which will create cmsdk users, folders, groups etc, however when I attempt to load a java class into the oracle schema using the command:
loadjava -user user/password@database -resolve classname.class
It generates error messages to the effect that classes (cmsdk classes) required by the class cannot be found. The class is loaded and marked with the status "invalid". Is it therefore necessary for me to load the cmsdk packages into the schema?
Cheers
David

Using CMSDK Java API within the database has never been supported
(see Problems loading IFS's java class into database
When we needed to invoke CMSDK code from our PL/SQL code, we used one of two approaches:
(1) use advanced queues to send requests to an external Java program (the CMSDK code, running outside the database) and receive the results back (asynchronous choice); or
(2) make an HTTP request to a Java servlet (the CMSDK code, running in some Java web container like iAS) and get the response back in some custom format (XML or something) (synchronous choice).
It seems to me that the CMSDK Java API was designed to be used only in middle-tier, not in database tier.

Daniel.

Calling jsp page from plsql

Please help me to the following
How to Call jsp page from plsql??
Please its urgent
Edited by: 883730 on Mar 19, 2012 12:05 AM

The best approach would be to change the behavior of your site so that it includes index.jsp as one of the default files. Typically that is done using the upper-level control files of the site. Here's a link from Sun that describes their approach.
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/WebApp4.html
Actually, you don't say what type of webserver you're using, so it's really hard to guess. But if you were using an Apache webserver, you might want to review the "DirectoryIndex" directive here...
http://httpd.apache.org/docs/2.2/mod/mod_dir.html
In fact, if you were using Apache and didn't want to do that, you could do a redirect to another page using the "redirect" directive in the webserver control files as described here:
http://httpd.apache.org/docs/2.1/en/mod/mod_alias.html#redirect

Calling Java API from ABAP using JCo (Part 2)

Hello,
This is an additional question to thread Calling Java API from ABAP using JCo
Has anyone managed to get the input parameter value
input.getString("REQUTEXT")
that is being passed from ABAP?
If yes, what kind of setting you need to do? Because when I execute, it has no value.
Thus, the below ECHOTEXT parameter returns blank value:
output.setValue(input.getString("REQUTEXT"),"ECHOTEXT");
When I debug by printing the below line, the input XML is indeed without value:
System.out.println(input.toXML());
Anybody knows how to pass input variable from ABAP to JAVA using JCo?
rgs,
hiroshi

Hallo Hiroshi,
as far as I can see, you are doing it the right way. The problem might be that the ABAP program does not fill in this parameter because something went wrong in the SAP System.
Have you tried setting a breakpoint (an HTTP session - remote breakpoint) and tried checking step by step if the value is being processed and put into the REQUTEXT field?
Bye,
Sameer

Calling Corba Java from PLSQL

Hi,
My question is about calling java functions from PLSQL. What we have is in-house developed java classes registered at the TAO CORBA service on Unix platform. We developed a PLSQL package that calls other PLSQL functions and procedures without problem. We also need to call Java functions registered at the CORBA service. I know that calling standard Java functions is not problem via loading with loadjava and publishing as PLSQL procedure and functions. However, I found that CORBA is no longer supported starting from Oracle 9g r2. Still, I wonder wether there is a way to call these java functions registered at CORBA without loading and publishing? Any help will be greatly appreciated.
Thanx in advance,
Sincerely,
Asaf

Hi,
I would just like to mention that we decided to utilize TCP sockets in PLSQL utilizing the UTL_TCP package. Socket interface is also implemented at the Java module and hence we can call the related the interface functions via UTL_TCP socket interface. I hope this might help those who face a similar problem.
Sincerely

Calling perl script from PLSQL

Hi All,
I have created Java stored procedure and oracle function to execute the os commnad, this works fine for calling batch scripts but when i used same function to call perl script,
like how we call in batch script
perl <script name> the sql gets hanged.
Is it possible to call perl like this?
or is their any other way to call from plsql
Thanks Chandra

Are you able to run that perl script at DOS command line?
Did you call the perl script directly from the java proc or you put the perl command line in a DOS .BAT scirpt and called that from the java proc?

CALL a report from WDA using SUBMIT to sap-spool

Hi,
I need to call a report from one of the methods of a WDA application.
The out of this report is a sapscript. I want show it in WDA (PDF).
The report is called when a user clicks EXECUTE button.
The piece of the code is:
call function 'GET_PRINT_PARAMETERS'
    exporting
      immediately            = 'X'
      new_list_id            = 'X'
      no_dialog              = 'X'
      receiver               = sy-uname
      release                = 'X'
      sap_cover_page         = 'X'
    importing
      out_archive_parameters = t_arcpar
      out_parameters         = t_pripar
      valid                  = i_valid
    exceptions
      archive_info_not_found = 1
      invalid_print_params   = 2
      invalid_archive_params = 3
      others                 = 4.
      submit hbrcced0
                      with pnppernr-low eq i_pernr
                      with pnpbukrs-low eq t_p0001-bukrs

                      with pnpendda     eq i_endda
                      with p_expot      eq ''

                      with respcc       eq v_sachn
                     to sap-spool
                     spool   parameters t_pripar
                     archive parameters t_arcpar
                     without spool dynpro
                     and return.
    if sy-calld eq ''.
      message 'err' type 'E'.
    else.
If i execute this code in WDA, the sy-calld never is equal 'X'.
But if i execute it in program (SE38) the sy-calld is 'X'.
How i can call the program 'hbrcced0' in WDA ?
Cheers,
Silvio Galery

Hi Silvio,
a submit REPORT to spool does work from WDA.
ONLY when "and return" is used.
You have that, so it should work.
Note you had print immediate on, so it will be output on printer,
and not available to read after the call.
(which option was the keep after print?, I would have to check docu)
The sy-calld will be set to X inside the REPORT when it is running.
After the submit has run back inside WDA it is of course reset to space again.
Cheers
Phil.

Calling Web Service from PLSQL. Does anyone do this regularly?

I grabbed the demo_soap package that is available on both metalink and on the regular oracle site, to try calling a web service from plsql to return the xml. I've had minor success, although I get an ORA600 error , for which I've opened up a TAR. However, the first reply was the I was hitting a bug (db ver. 9206) that had to do with getting 100m in xml in a response. I'm nowhere near that size, and the largest xml response I've been able to generate from the service was 400k (k not m). It doesn't seem that huge. Does anyone work with calling a web service from plsql? Have they had success?
Thanks

Well, you should first test if your webservice is reachable with a simple WS - Client or a Browser - Plugin, then verify the respones of the web service and after that you can take further investigations on your problem domain. The error - message refers to a line in your function, obviously, but I can't see which line and because there is more than one call to sys.utl_dbws I don't see at what point the script fails. NULL - Pointer - Execptions usually indicate that a method was invoked on a variable which should contain an object reference but is NULL.

Calling Web Service from CRM using proxy

Hi all,
I'm facing a problem trying to call a web service from CRM (WAS 620) via XI 3.0. The response that XI recieves from the web service contains SOAP Envelope, and the mapping fails because of it. I built the proxy manually, because if I load WSDL the proxy generation in CRM generates error that sais that external definition coudn't be used.
Is there any way to remove SOAP envelope from the response while mapping?
Is it possible to call web service from WAS 620?
Thanks!!!!
Anya.

Hi Manish,
SOAP adapter does pass the message to XI (this message contains SOAP envelope although XI expects to get message without it), and during the mapping step i get "Runtime Exception in Message-Mapping transformatio~".
I suppose it's because i created proxy manually. I did so because when i imported WSDL, and tried to generate proxy in CRM, i got an error message that said that proxy couldn't be generated because external definitions are only allowed in XI 3. But my XI version is 3.0! And when I generate the same proxy in my R/3 system that is installed on WAS 640, it works.
What can I do?
Cheers,
Anya.

Calling stored procedure from VB using OraOLEDB.Oracle

I have a simple stored procedure with two parameters:
PROCEDURE Test1(
pOutRecords OUT tCursorRef,
pIdNumber IN NUMBER);
where tCursorRef is REF CURSOR.
(This procedure is part of a package with REF CURSOR declared in there)
And I have two database schemas: AppOwner and AppUser.
The above stored procedure is owned by AppOwner, but I have to execute this stored procedure from AppUser schema. I have created a private synonym and granted the neccessary privileges for AppUser schema to execute the package in the AppUser schema.
When I ran the above procedure from VB using ADO and OraOLEDB.Oracle.1 driver, I got the following error when connecting to the AppUser schema:
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'TEST1'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
but when I was connecting to the AppOwner schema, everything is running correctly without errors.
Also, when I switch to the microsoft MSDAORA.1 driver, I can execute the above procedure without any problems even when connecting to the AppUser schema.
I got this error only when I am trying to execute a stored procedure with an output parameter. All other procedures with only input parameters have no problems at all.
Do you know the reason for that? Thanks!

Calling Java API from ABAP using JCo

I need to call Java API from ABAP & BSP also. For this I have got useful information related to JCo from following blog:
/people/gregor.wolf3/blog/2004/08/26/setup-and-test-sap-java-connector-outbound-connection
But, I am facing one problem. On executing Java program myExample5.java (recommended by Gregor Wolf) from command line I get following error message:
Server JCOSERVER01 changed state from [ STOPPED ] to [ STARTED ]

Can anyone please help me out. Do I need to do any setting?
I'll surely reward points.
Thanks & Regards,
Nilesh Kumar

Hi Nilesh,
From the error i think that the error is with the hostname.
Please enter the the Application Server IP/Hostname.
If you are loggin to SAP System "XX1" from SAP GUI. Then click the change Item tab and see Application server name/IP let say "XX2" for hostname or "xx.xx.xx.xx" for IP.
Replace srv[0] = new Server("gateway","sapgw00","JCOSERVER01",repository);
with srv[0] = new Server("XX2","sapgw00","JCOSERVER01",repository);
If App Server is IP then replace with
srv[0] = new Server("xx.xx.xx.xx","sapgw00","JCOSERVER01",repository);
Let me know if it is throwing any error.
Thanks,
Prashil
