Application Express :: PDF Printing With FOP / Apache Tomcat / J4LFOP Server In Windows?
Dec 15, 2012
I have been learning to create pdf report with Apex 4.2 and BI Publisher 10 which I have been successful with. Now I like to learn how to create pdf reports using FOP thinking of the customers who will not spend money on BI Publisher. I have gone through the documents and procedures described in Java 4 Less. [URL] and [URL]. Configured Apex instance setting accordingly.
For default layout a tabular pdf report is created. I have created an xsl-fo file named Formatted_report.fo on same query and xml file from report query with BI Desktop. But when I try to print a formatted output with Formatted_report.fo report layout it does not work(J4LFOPServer ). but same layout with .rtf template works fine (BI Publisher Print Server).

I tried my DBA hat today in an effort to set up the Apache FOP to allow users to download interactive reports as PDF. This was working previously - although I'm not sure how since there was no report printing infrastructure set up.We have APEX 4.1.1 using Apache on Windows server 2003.
It started because we saw one of two errors in the generated PDF
ORA-20001: The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified.or
ORA-06502: PL/SQL: numeric or value error: character string buffer too smallAs much of the documentation indicates, the first suggests a problem with ACL. I had a little trouble finding documentation stating specifically which acl should be defined for IR PDF printing, but we did ensure the listings in the dba_network_acl* views were current with
[code]...
/I'm still unable to identify where the second error (ORA-06502) is coming up - which is apparently new. So I attempted to deploy the fop.war file using EM, adapting instructions from [URL]...though I think I may have missed a mark since these instructions differ from using the OC4J EM - but I guessed there was fair correlation.
From the EM home on our app server, I created a new OC4J instance called "APEX_Reports"I then went to deploy the fop.war file using "fop" as application name, and "/fop/" as the map to url.
Back in APEX instance management, I set up
Print Server: External (Apache FOP)Protocal: http
Print server address: dev.ouractualdomain.com.au
print server port: 18100
Print server script: /fop/apex_fop.jsp>
I used the same port as that in the EM address. I've also tried variations usinglocalhost8888fop/fop/apex_fop.jsp
The reason for the /fop/fop/ attempt was because I located the jsp file in
C:Ora10gFRShomej2eeAPEX_Reportsapplicationsfopfop
(I've been trying everything)
Other port numbers attempted include those types (JMS,RMI,AJP) listed for the APEX_Reports component.Do we need to restart anything or re-login to APEX before testing modifications?

I am building an application to edit database data through interactive reports. I would like to add a button to open a pdf file of the report, where the user can save or print it. I tried going to Shared Components>Report Queries and then create. I went through the steps but when I get to the end where it says "Test Report" I get this error:
ORA-20001: The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified
What can i do to fix this, or is there an easier way to do this?
I am using APEX 4.0.2.00.09
This app will be distributed to other computers if that makes any difference.

I'm using APEX 4.0, and i don't have access to BI Publisher for printing.
That needs to print off customer address labels.
I have a pl/sql query that gets the customer name and address and puts it into mailing address format.
Ex. Mike Smith
555 Oracle Dr
Los Angelas CA 40455
When i try to print from the browser, it prints really bad with the URL, page numbers etc.
These will actually print out on label paper, and they will be cut and used accordingly.
What i tried so far:
Manipulating the print CSS:
This worked slightly in Firefox, but doesn't work at all in Internet Explorer
Tried adding a third party friendly print button to the application. This doesn't work
I would even be ok for these to print to a PDF or RTF format to download then print off, but i don't have BI Publisher.

I'm using APEX 4.2 and trying to export some classic reports to PDF. I followed these directions to install BI Publisher: URL.....Entered these values in the Apex Administration Report Settings section:
Print Server: BI Publisher
Print Server Protocol: HTTP
Print Server Host Address: URL.... (also tried with localhost and failed)
Print Server Port: 9704
Print Server Script: /xmlpserver/convert
Back in my Classic Report, I configured these settings in the Print Attributes tab:
Response Header: Report Settings (also tried with Print Server and failed)
Print URL: f?p=&APP_ID.:7:&SESSION.:FLOW_XMLP_OUTPUT_R7671716059006280
I'm getting this error: report error: ORA-20001:
The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified.I have never configured PDF printing this way and am pretty lost.

I am using "Function Returning SQL Query" (as query is dynamic) to draw the bar chart (flash).
I am facing some issues while trying creating a BI report for this chart.
Issue is : In Shared Components -> Report Queries : Its only expecting an SQL Query.
Do we have any ways to define a "Function Returning SQL Query" over here ? Note that, If using a static SQL both charts / BI reports are working fine with out any issues.

I'm attempting to configure printing via the APEX listener and I'm struggling to understand it. I currently use Oracle HTTP server as the web server for APEX. I have installed the APEX listener and configured it. If I connect via the APEX listener, PDFs work correctly. If I connect via the Oracle HTTP server, I get an error with PDFs. Am I required to connect with the APEX listener for PDF printing? I thought I could configure APEX listener for PDF printing on the backend and still connect via Oracle HTTP server. I'm use APEX 4.2.3, APEX Listener 2.0.5, and Oracle DB 11.1.0.7.

I followed the directions to print a report using this documentation [URL]....where I setup a report query and a report layout and then add the url to a button that when clicked opens up the report in my chosen format. This all work very nicely. However, I need to update the table behind each record that gets printed and I cannot figure out how to couple the print request and an update process in APEX.

O/S: Windows 7 64-bit
DB: Oracle XE 11g2 32-bit
APEX: 4.0.2
=============
Trying to upgrade APEX within an Oracle XE database installation on Windows 7. The version of APEX that came with Oracle XE is 4.0.2. Trying to upgrade to 4.1.1 and, from the SQL*Plus command-line (ie. the 'Run SQL Command' tool which comes with Oracle XE), I try to run @apexins.sql.
It starts to run momentarily, then the MS-DOS windows just closes. Can not find any install log to determine the cause.

I have set up a label which interacts with our LIMS system. I have set up variables on this label which pull in attribute values from the available tokens. When the attribute value is null, the label is automatically inserting 'N/V' onto the label.
I would prefer for the variable to appear as a blank field on the label when the attribute value is null in the LIMS. can't find anything in the user's manual. Perhaps there is some setting where you can define what to display for null values. I can't seem to find any information on this.

I'm trying to migrate an Apex Application from one server to a newer server . My custom app I used the theme from Go Live CheckList samples....
Well, when trying to install that application I get 'Insufficient space to install application ' with a BIG red X... I was able to install other Package Application except for the one I need and now my application errors out because of some shared Themes. At first I thought it was a DB thing so I downgraded back to 10g from 11....but that didn't work... Apex works fine...
Other samples work fine...Version Apex 4.2.2 and Oracle XE 10g...

after my first Apex installation I have got the above mentioned error. I have tried the following Apex calls:
localhost:7778/apex
localhost:7778/apex/apex_admin
Instead of using localhost I used the hostname or the IP address of the box without success.The whole installation process went fine from scratch. No errors, no warnings, nothing.I am using the following environment:
CentOS 6.3
Oracle 11.2.0.3 EE
Apex 4.1.1
With exec dbms_xdb.sethttpport(7778); I enabled the above port number. If I look at the output of the lsnrctl status I see that my local listener is also listening on 7778. I have no errors in the alert.log and no other trace files where I can have a look at.

I am hoping to test the behavior of a complex web application that is backended by an Oracle 9i database, against an upgrade to 11g database.
The current setup runs basically on 4 Solaris servers, The database, the Oracle Application Server (version 10 something) (2 instances running on the node/server with no OHS), an install of OAS/OHS as a load balancer box, and the non-OHS Apache2 web server front. Apache takes the request from the web and reverse-proxies it to the OHS load balancer, which sends it to one of the two instances on the single application server. This is a java application and uses an Oracle 9i database to feed it.
I have had enough server resources to clone the database, the app server and the web server, and upgrade the database to 11g. I am unable to setup an OHS load balancer box.
So my question is, how do I configure the Apache WS to communicate directly with the OC4J container(s). I can shut down an instance if that simplifies things. Or, if I had to I could look into standing up OHS in the OAS install, as that seems to be where all the info is focused on the technical info sites (Oracle and others), but since these are clones and I think it might be easier to just short circuit around the now missing load balancer box. Many configurations have already been done to be sure the 'clone' identifications are self-referencing, like the hosts file, etc. to point to resources in the Cloned environment.

This error occurs while trying to print a report in a PDF format using Oracle Application Express 3.0. I'm not sure what this means and how to fix it. I'm running Oracle 10g on Windows Vista.
ORA-29273: HTTP request failed
ORA-06512: at "SYS.UTL_HTTP", line 1186
ORA-12570: TNS: packet reader failure
This is the first time I'm attempting to print to a PDF. I did follow configuration according to the Oracle documentation. I selected the Standard configuration that uses the built-in Apache FOP or another standard XSL-FO processing engine.

We have an application, where we invoke a URL pointing to a folder on the Application Server, so that users can download files from the same.
There is user authentication provided for the URL.
Example :
Our application ABC (example) which is built with Oracle Forms 10g, hosted on Application server (itxxx123) inovkes a module GEN9999 which on pressing a button calls a URL which is open in the Internet Explorer browser.
If the URL has been called from the Forms or the Application (ABC), then it should be allowed.
If the URL is called standalone, by Opening IE Browser and invoking the URL, this should not be allowed.
However, there have been security concerns raised during Audit, saying that users can access the URL directly from the Browser instead of the Application. Also the URL is saved the Browser history, so even if the user is no longer working in the Application Team, and has moved out of the team, then the ex-user can still access the URL and view and download files.
Is there any way to restrict access to the URL such that is only accessible when it is called from the Application, and that access is restricted when directly called from the Browser.
I have seen that environment variables in httpd.conf may be usable for the above. However, not sure how to use them from Oracle Forms.

I'm trying to create a web service via the WSDL wizard (Apex 4.0.2). We are behind a firewall and connect to the internet via a proxy server. The proxy server requires authentication with a username and password. How to include the username and password in defining the Proxy Server in the Application Definition page or optionally in the alternate location in the Manual Web Service wizard page?
I assume the base definition for the proxy server is [http://]host[:port][]

I'm having some difficulty securing my Oracle APEX + Oracle HTTP Server environment.
There are currently around 20 Applications running on the APEX Server, and I'd like to publish 2 of them Externally for users.
I have added a certificate to Oracle Wallet Manager to secure the OHS, but I can access all the Applications on the APEX Server by just changing the Application ID suffix.
How can allow only two applications to be accessible via the internet?

I am trying to use embedded weblogic server for creating an LDAP authtication secheme but it is not working
I believe that embedded ldap server works on the same port as the admin server of the domain but configuring it has been a pain. I got the following code from forum to test the ldap connection
declare
l_retval pls_integer;
l_retval2 pls_integer;
l_session dbms_ldap.session;
l_ldap_host varchar2(256);
[code]........
Every time I run this, I get the following error

Environment:
Apex 4.2
DB 11gR2
I've started using Apex 4.2(new to Apex). I have built a form based on a table with a date column on it. The form allows update on all fields/columns of the base table. For the date field/column, the goal is to present the user with sysdate on load and update the date with sysdate if the record is changed any of the fields. How can I accomplish this?

I have installed Oracle 11g XE . After this , i have upgraded to Apex 4.2 All it's working fine, but..... by default XE installs and configure apex to use embebed pl/sql gateway.
In this scenario, the images are stored directly in the database within the oracle XML DB repository. This may be a problem because XE have a 11GB limit and my apex aplication is simple, but it may upload pictures for customers, etc, and in this schenma the pictures will consume space in the database instead consuming in the linux filesystem.Can i install HTTP server in a 11g XE and reconfigure apexr?, or can i change to apache+listener? or more easy....can i upload images outside the XML DB in my apex application easily?

We have Oracle DB 11g.I want to develop a small application for internal use the company.I have used Oracle Application Express workspace provided by Oracle and I thought of using Oracle Apex is the right tool for our internal reporting.
But I am not sure what is needed in order to start developing the application in-house.What should I check with the DBA team in order to find out if I can use Oracle APEX in the organization.Is there any prerequisites, web Server, etc that is needed in order to use Oracle Apex?
