Consuming of SOA webservice in Oracle APEX

Hi All,
I have a requirement in which i need to consume the data into Oracle APEX from a web service which was created in SOA. (For eg: There is a webservice created in SOA, which posts empid,empname,empsal etc)
Now, in Oracle APEX i need to use that data consumed from the webservice to display graph or report , is that possible?
Can we build graph or report or such things in Oracle APEX without creating any tables/views etc in Oracle APEX?
If the above question looks complicated, here in simple mode:
Is there any way in which we can build a graph/report in Oracle APEX with out creating a table/view in APEX for the data that belongs to Oracle E-biz instance.
Hope I am making sense from the above question.
p.s: APEX 4.2 is the version that we are using now.
Any Help/guidance truly appreciated,
Thanks in Advance,
Af

Hi Af,
I have explained the steps in another thread which I have given link in my previous reply.
If you are looking for code for any specific step, please let me know.
And another point you need to take care is - Authentication. If it's a public web-service, then no problem. If it uses basic authentication, then you can pass username and password to APEX_WEB_SERVICE APIs.
I also suggest you to try invoking web-service using stand-alone clients like SoapUI - The Home of Functional Testing. If everything works fine there, then you can try them invoking from APEX.
Regards,
Hari

How fetch data from a view(which is located in different server) using Oracle APEX webservices

Hi,
I have a requirement to fetch the view data from client instance(which is different server) to another instance lets say Development instance
Requirement:
Need to get the Apps View data from the Desired EBS instance(which is accessible online) using webservices,and display it in the Oracle Apex Development Instance.
Kindly provide your inputs how to achieve this.
Thanks in advance

Are you getting an error? The way you have it set up, you can have an error and it will never be displayed. Put and error control on your front panel and see what it gives you. Also, shared variables in a project can be useful. Look at some examples for that.

How to consume J2EE webservice in Oracle BPEL

Hi,
What IDE are you using?, for example with Eclipse i used WSDL2JAVA plugin in this way i converted the WSDL in java classes easily. Depending your development environment you can use different tools that makes easier the integration using the WSDL.

Calling a webservices from Oracle 10G ( 10.2.0.2)

Hi:
I am in the process of putting a database Java stored procedure that can call an external webservices.
PL/SQL Wrapper -> Java Stored Procedure-> External Web services
I loaded the following jars in the dataase.
dbwsa.jar
dbwsclient.jar
1. I am having issues consuming this external webservice from SQL*PLUS. Do you know whether I need to load any other JARS ?
2. How can I debug this issue ? I enabled TCP Monitor in JDeveloper and don't see anything when I call the PL/SQL wrapper in SQL*PLUS.
3. I can use a Java client and tested the Web services OK.

thanks Tugduall for the comments. here are the instructions I followed to create a java stored procedure that can call a webservices. Unfortunately, this seems like a very complex task. Do you have any ideas how I could debug or troubleshoot this issue ?
Please note that I used JDeveloper to generate the client code.
========================================================
1. download the dbws-callout-utility-10R2.zip from OTN at:
http://www.oracle.com/technology/sample_code/tech/java/jsp/dbwebservices.html
2. create an application/project with 1.4 JDK.
3. create a web service by ‘Business Tier’->Web Service->Web Service Proxy->UDDI
4. next… to ‘Search for’, type ‘quote’.
5. from the list select one. For me ‘Quote of day’ was picked.
6. click Next all the way to Finish.
7. from the ‘Application Sources’ select ‘QuotoProxy’ then find its main method.
8. at the section
// Add your own code here, add the line like:
System.out.println("quote "+myPort.getQuote());
9. run it to see its return.
10. cteate a class that has a method to call client method to be invoked (static)
like the following:
package dbws;
import dbws.QotdPortClient;
public class MainClientStub {
public MainClientStub() {
public static String getMyQoute(){
QotdPortClient myClient = null;
try {
myClient = new QotdPortClient();
return myClient.getQuote();
} catch (Exception e) {
e.printStackTrace();
return null;
note that the package name in your project.
11. create a deployment profile as ‘JAR File’. Uncheck the box ‘Project Dependencies’
12. deploy it to the local box. ‘Deploy to JAR File’.
13. unzip the dbws-callout-utility-10R2.zip to get dbwsa.jar.
14. execute the following from command line:
loadjava –user test/[email protected] -resolve –verbose –synonym –grant public to dbwsa.jar myarchive1.jar
loadjava -user test/test@orcl1020 -resolve -verbose -synonym -genmissing -grant public myarchive1.j
ar dbwsa.jar
loadjava -user sys/<sys_pass> -resolve -verbose -synonym -genmissing -grant public myarchive1.jar dbwsa.jar
15. create a function like the following:
CREATE OR REPLACE FUNCTION teststub RETURN VARCHAR2 AS
LANGUAGE JAVA NAME ‘dbws.MainClientStub.getMyQoute() return java.lang.String’;
16. Run at sqlplus: Select teststub from dual;

Insert a record into a table through email in an Oracle APEX application

I developed an Oracle APEX application, there is a table called events. I can insert/update/delete a record in the table through browser. I am thinking in order to quickly do the data entry, user should be able to send an email, then the table should be inserted with values from email address, timestamp, subject and body. Anyd idea how to realize this functionality?
- Denis

Start by checking whether your mail server provides any API's for accessing emails , if it does you might be able to reduce a lot of work by using some kind of web service consumer from apex to your mail server. In any case your implementation is going to be dependent on your Mail Server configuration.
Your problem breaks down to reading/accessing mails from the mail server from PLSQL (apex is driven by PLSQL).
I found this other thread which could be of some use.
WAY TO ACCESS A MAIL SERVER FROM ORACLE APEX
<li>The following package might solve your problem directly(from carsten czarski of the German Apex community)
[url http://plsqlmailclient.sourceforge.net]http://plsqlmailclient.sourceforge.net
PS: POP3 support is still TBD.
<li>I also found this posting in the orafaq forums which lists a java method and PLSQL code bit for it for accessing emails via POP3
[url http://www.orafaq.com/forum/t/80928/2/]http://www.orafaq.com/forum/t/80928/2/
If these do not work for you, find some java library to read mail from your server, write a PLSQL wrapper for it and use it in a scheduled job(DBMS_JOB)/a PLSQL block triggered from Apex.
If you get stuck there, find some utility that can read mails, invoke them from your DB using java,shell scrpt,dbms_scheduler etc and use the utility's function for the rest.
NOTE: I haven't tried any of these utilities and you must validate any java code before running them on your environment.
Since aren't really much restrictions(other than spam checks) in sending a mail to your mail account, you might want to consider filtering out the mails from which you create records.

I've encounter something similar to you're problem and it was resolved by manually creating the object using the web service constructor and inputting user credentials. If you manually instantiate your web service wrapper object and set a a security profile token, it may solve your problem. You can also pass in the web service endPoint URL, if you want.
Fuego.WebServices.UsernameTokenProfileSecurityPolicy
I'm not sure how to use UsernameTokenProfileSecurityPolicy, but try something like this:
Fuego.WebServices.UsernameTokenProfileSecurityPolicy policy = UsernameTokenProfileSecurityPolicy();
policy.username ="mark";
policy.password = "password";
tws = YourWebService();
response = tws.callWebServiceMethod();
I realize the security profile isn't tied anywhere to the web service, but try it anyway.
There is also some fields on the webservice, tws.setRequestHeader() that may allow you to set the username and password on the request, but this doesn't make sense to me. It shouldn't be that hard.

How to pass a value to a bind variable in a query report in oracle apex

Hi Guys,
I have requirement to send weekly reports via email to some users. The users should receive their own records in the report. The user details is stored in a table. What I am planning to do is to create a report query in oracle apex to generate the report and then run a function/procedure via a scheduler to email the report to respective users. Now my query is ............. is it possible to pass a value (user name) to the report query to pull records of only that user? I know we can have bind variables in the report query but I have no idea how to pass a value for bind variables from a function/procedure.
Can anyone help me on this issue or suggest a better approach?
Thanks,
San

Getting error while importing the application in Oracle Apex

Hi,
I am facing an issue while importing an application into my new Oracle Apex installation. Installation was successful with out any issue. I exported an application from my old Apex (version 3.0.0.00.20) and importing the same into new apex (version 3.0.1.00.08). I am getting the following error.
============================================================
The requested URL /pls/apex/wwv_flow.accept was not found on this server.
============================================================
When I click on import in Application Builder page and then browse the required file it gives the progress saying "Importing File" and after some time it displays the above error.
I tried bouncing the application also and there is not error in alert log.
Could any one please suggest, if there is some problem here. Or my approach is not correct.
Thanks in advance.
Regards,
Advait Deo

Osacar, I recommend that you try to import the application into your workspace on apex.oracle.com and see what happens. Also, refine the problem statement as much as you can, e.g., you get this error importing "the application" or when importing "any" application. How big is the file you're trying to import? Where did it come from? Can you upload images?

Does anyone have any solution how to escape the single quotes in Oracle APEX 4.2. - like \' or something? I already tried using backslash but had no luck.
Would really appreciate your help ASAP.

execute immediate 'update emp set sal = sal * 1.2 where ename = ''SCOTT''';However a better approach when dealing with SQL strings is to use the alternative quoting mechanism:
execute immediate q'{update emp set sal = sal * 1.2 where ename = 'SCOTT'}';as this allows the original string to be left unaltered.

Issue in Upgrading Oracle APEX 2.1 to 3.1

Hi,
I have recently installed Oracle Database 10g Express Edition (Oracle Database XE) which includes Oracle Application Express (Oracle APEX) release 2.1
I have upgraded from Oracle APEX 2.1 to 3.1 by following instructions in http://www.oracle.com/technology/products/database/application_express/html/3.1_and_xe.html
Following is the sequence of steps I followed
1. @apexins SYSAUX SYSAUX TEMP /i/
2. @APEX_HOME/apex/apxldimg.sql APEX_HOME
3. @APEX_HOME/apex/apxxepwd.sql password
Now Oracle Database express home page changes to
http://127.0.0.1:8080/apex/f?p=4550:1:723721796272276
All gif logos are missing and font appears differently. More importantly nothing happens after entering workspace/username/password and clicking login button. I am using internet exlorer 7 and it says "Error on Page" on the bottom status bar.
Please let me know if any one encounterd similar issue and if you were able to fix the issue.
Thanks for your help
RSNAIK

Hello,
For all of you who have the same problem that we had.
After two installs and desinstall, I have finally found what to do.
You must stop the OracleXETNSListener service when upgrading Oracle Database 10g Express Edition.
Here the steps to follow assuming that you have installed Oracle Database 10g Express Edition into C:\oraclexe
and unzipped apex_3.1.2 into C:\apex on a Windows XP System :
1. On Windows XP, Startup Menu, go to the Configuration panel, open Administration Tools, open Services, then you will click on the OracleXETNSListener service, stop it.
2. On Windows XP, Startup Menu, select Execute, type cmd and press OK to open a DOS window.
3. At the DOS prompt, type cd apex.
4. At the DOS prompt, type sqlplus /nolog
5. At the SQL prompt, type connect SYS as SYSDBA
6. Type the password of the user SYSTEM that you choose when installing Oracle XE.
7. At the SQL prompt, type *@apexins SYSAUX SYSAUX TEMP /i/* (may take 15 minutes or more)
8. At the DOS prompt, be sure to be in the apex directory (C:\apex) then type sqlplus /nolog
9. At the SQL prompt, type connect SYS as SYSDBA
10. Type the password of the user SYSTEM that you choose when installing Oracle XE.
11. At the SQL prompt, type *@apxchpwd*
12. Choose a password for ADMIN, type it then press Enter
13. At the SQL prompt, type *@apxldimg* C:\ (you will perhaps obtain a message like an error but the upgrade works fine)
14. At the SQL prompt, type *@apxxepwd* password (where password is the ADMIN password choosen at step 12)
15. At the SQL prompt, type quit
16. At the DOS prompt, type exit
17. Then go to the OracleXETNSListener service and start it.
To connect as ADMIN, type the url http://127.0.0.1:8080/apex/apex_admin
username : ADMIN
password : your admin password
You will be able to create workspaces (schemas) and users
Now you will be able to connect to APEX at http://127.0.0.1:8080/apex
workspace : your login name (workspace created in apex_admin)
username : your login name (user created in apex_admin)
password : your password (password defined for the user in apex_admin)
I hope that this steps will be clear for all of you.
Thank you to user10570446 who have provided a clear step through. So that I'd take the time to clarified my solution to my type of configuration.
I hope that RSNAIK has been able to make the upgrade to APEX 3.1.2.
Good day to everyone
