Apache FOP config Question

Hi all,
I have APEX version 3.0.1 and I use F&R Services version 10.1.2.0.2. I wanted to use Apache Fop in order to have PDF Printing facilities.
However in http://www.oracle.com/technology/products/database/application_express/html/configure_printing.html#05
I saw that the OC4j version needed should be a minimum of 10.1.3.2 version. So I decided to use the OC4j from JDev 10.1.3.3.
Step 1 from the document above went ok, then when I try to configure FOP in APEX I cannot find "Instance Settings", under Manage Service, even though I am logged in as ADMIN.
Has anybody any suggestions on this?
Kind Regards,
Ana-Maria

Hi all,
found the problem. I needed to connect as admin to APEX in order to do this: http://hostname:portno/pls/apex/apex_admin.
Thank you,
Ana-Maria

PDF generation with Apache FOP.

DB: Release 10gR2 -> 10.2.0.3
Apex : 3.1
OS: Linux RedHat 4 Update 6.
Apache : 1.3 from the Companion DB CD.
Our enviroment have been done with 10gR2 and the Companion CD Apache, are running in diferent servers.
I was trying to follow the steps for get the apache FOP working reading the document.
http://www.oracle.com/technology/products/database/application_express/html/configure_printing.html#05
Step 5.1
Oracle Containers for J2EE (10.1.3.2)
Available for download from OTN
Installation instructions and configuration
I don't see the 10.1.3.2 at OTN. Actual releases are 10.1.3.3 -> 10.1.3.4
Can I use any other one newer?
What to download ?
The Oracle Containers for J2ee (OC4J)?
Any other one?
Thank you in advance for your help
Jose

As part of the ducomentation to install the OC4J. You have to have the JAVA_HOME , ORACLE_HOME and J2EE_HOME.
According to document
http://download.oracle.com/docs/cd/B32110_01/web.1013/b28950/install.htm#CEGBCJJH
Question:
If I have install the Apache from the Companion CD and my ORACLE_HOME is
/u01/httpdev2/oracle/product/10.2.0
The directory have the j2ee and others. If I try to install the OC4J I will be overwriting the rest of directory.
How I install the OC4J?
I have to create a new ORACLE_HOME?
I have to install Application Server and then the OC4J?
Thank you.
Jose.

PDF printing by Apache FOP : what are the prerequisites ?

Hello,
I'm actually looking for a way to print reports, and I've 2 questions :
1) If I'm not wrong there are three means : BI Publisher, Apache FOP and an other XSL-FO like Cocoon...
-> For budgetary reasons, we can't use BI Publisher.
-> Besides, my company owns the Oracle Standard Edition, so I'm not even sure we can use Apache FOP : in every documentation FOP is deployed in App Server or Enterprise Manager, and we don't have those. OC4J seems installed on our server but it may not work without Application Server...
-> So is Cocoon the solution ?
2) We're about installing Apex 4.0. We want to be able to print interactive reports, with aggregations and sums. Does it possible and are there differences between report engines ?
Thanks a lot !
Fanny

Hi Fanny,
I stand to be corrected, but my understanding regarding OC4J licensing is this.
OC4J can be downloaded and installed in standalone configuration from OTN under the OTN license, which is fairly restrictive and means that it cannot be used for production or commercial purposes. This applies whether it is installed on the database server or on a separate server. In order to license it you need to buy an OAS or Weblogic license. This is in contrast to Oracle's HTTP server, which can be installed standalone and is included in the database server license provided it is installed on the same server as the database. If the HTTP server is installed on a separate server to the database then it too requires an OAS or Weblogic license.
My guess for this anomally is that the HTTP server is based on Apache, an open source product and it was originally installed as part of the database up until version 9i. After that it was separated out as a companion product. Where as OC4J is based on a proprietary product called Onion, which Oracle acquired. Commercially going forward, Oracle is pushing Weblogic. If you want a free app server then you can opt for the free version of Glassfish, an Oracle product or Tomcat.
If you do need a supported environment you can also get Standard One versions of Weblogic and OAS which are considerably cheaper than the Enterprise versions and you can get a supported version of Glasfish for around the same cost.
You should also note that Oracle BI plus OAS or Weblogic is a complete development and deployment product for business intelligence reporting, whereas Apache FOP and an app server is purely a deployment environment. If you wish to do something more sophisticated than the standard PDF option available in Apex, which is pretty basic, you will need to acquire some sort of XSL-FO production tool. As alluded to previously, Java4less produce a minimally priced one, but there are others in the market place.

Andre

Apache FOP PDF Save in BLOB column

Hi,
I just want to call Apache FOP in an APEX process to create PDF reports and save these reports in a BLOB column in the same database. So I can email these reports in another process using APEX_MAIL. Does anyone know a way to achieve this?
Thanks

If I understand correctly, your requirements needs to be broken down into two problems:
1) click link that pops up a window displaying a new APEX page
2) an APEX page the displays the document, not downloads it.
I haven't done #1 (yet).
However, you may be able to generate a URL that points to the new page as part of the SELECT statement for the Report.
This has a related question, but no answer yet:
open pdf in popup browser window
The key is target="_blank" for the anchor tag.
To generate the URL, you should use the APEX_UTIL.prepare_URL() function.
If that doesn't work, a Dynamic Action that does some magical JavaScript stuff may be needed.
For #2, I lost the URL that showed how to display a PDF as part of a "form" page.
From what I remember:
Start with a blank page with one blank HTML region (all the Items go in the HTML region)
Add an Item for the PK/Doc_ID
part I forgot Create a Data Manipulation Process
- Automated Row Fetch
- On Load - After Header
- (stuff for your table/view)
part I forgot Create an (I believe) "File Browser" item type. For Settings:
- Storage Type "BLOB column specified in Item Source" (and place the column name of the BLOB there)
- MIME Type Column: (column name) -- since you have multiple types, this is a MUST HAVE
- Filename Column: (column name) -- I highly recommend you have this.
- Content Disposition == INLINE <-- this is the kicker
Also, you will need a Browser Plugin for each of the MIME Types (otherwise, the browser may try to 'download' the file)
Browsers can handle Image types internally. Adobe's plugin can handle PDFs. I don't know about Word/Excel.
Again, I don't remember the exact details, but that should cover most of it.

Apache FOP getClassLoader problem

I have loaded Apache FOP 1.1 into an 11g database, and a driver class to retrieve XML/XSLT and save PDF as CLOBs. When I try to execute this in the DB, I get
ORA-29532: Java call terminated by uncaught Java exception: javax.xml.transform.TransformerException: java.security.AccessControlException: the Permission (java.lang.RuntimePermission getClassLoader) has not been granted to ProtectionDomain (null <no signer certificates>)

It looks like the SecurityManager is only looking at PUBLIC permissions, even though the FOP classes were loaded into a schema with 'SYS:java.lang.RuntimePermission', 'getClassLoader', ''.
Any ideas on how to get around this?
Thanks!

Dear Brian,
It looks to me like org.apache.fop.apps.Driver might be doing a
Class.forName() for the Loggable class. If Class.forName() does not pass a
specific classloader, the system classpath loader is used; which is why it
works when you put the classes on the system classpath.

Apache FOP and BI Publisher

If we are configuring BI publisher should we have to configure Apache FOP too.
How will it determine which one to use.

Pls ignore my question. I think I got it. Its either Advanced or Standard.

I have a similar problem, I tried to package the fop library with an ear also. I think it has to do with System properties. The fop library loads it's parser class from a system property, the class it finds is a weblogic library and that's when the problem begins. I was never able to solve this, but hope this gives you starting point. Keep us abreast of your findings.

FOP processing question

I am generating letters using report queries / layouts and calling apache-FOP.
I need to stored the resultant PDF in the database.
I am thinking of creating an intermediate web service (Java) which will call the FOP engine and return the PDF stream back to Apex, and at the same time update the blob in the database with the PDF object.
Questions are...
1. Has this been done before?
2. Is there a more sensible solution?
3. How does Apex call the FOP engine and with what parameters?
Any help / suggestions would be great.
Thanks
Paul

check this Re: how to save pdf in APEX 3.0

Do I need to use Apache FOP ?

Hi,
I am configuring Oracle BI Publisher with APEX following the instructions in http://www.oracle.com/technology/products/database/application_express/html/configure_printing.html .
After completing step *3 Installing and Configuring Oracle BI Publisher on Windows* I am able to print reports in desired PDF, DOC, XLS format etc from APEX and all the functionalities seem to be available.
So my question is why should I follow step *5 Installing and Configuring Apache FOP* ? Is there any other extra benefit of doing that ? Am I missing anything here ?
Please advise,
Thanks
Ashish Agarwal (PMP, OCM & OCP)
http://www.dbcon.com.sg

Hi Ashish,
Sure, not a problem, please see my answers below:
1) correct, you either use BI Publisher or Apache FOP or other XSL-FO processing engines as stated under #6
2) the main advantage of using BI Publisher over Apache FOP is that BI Publisher allows for WYSIWYG report layout creation using the MS Word plug-in, and then using these templates as RTF based report layouts in Application Express. With Apache FOP or other XSL-FO processing engines you can't use RTF layouts, so you would have to design your report layouts using XSL-FO, which if done manually isn't exactly easy. There are other third-party visual design tools available though that provide help with that, just google for "xsl-fo design". Also, BI Publisher of course provides several advanced reporting capabilities when using this product directly, that are not available with the APEX / BI Publisher integration.
3) BI Publisher Desktop, i.e. the MS Word Plug-In is part of the BI Publisher product, it's not a stand-alone product. So if you're a licensed BI Publisher user, you're also licensed to use BI Publisher Desktop. And BI Publisher Desktop doesn't provide much value if used stand-alone without the server.

Marc

A few post config questions on new setup

Hi Group,
Just a few post config questions.
First, how can I confirm my controller is in fact associating properly with an NTP server? On a typically cisco product, I could just do a 'show ntp associations' or a 'show ntp status'. I cannot see a way to confirm this on the gui or command line.
Second, on my guest network with web-auth, if one were to choose to not use https for web-auth and instead use unsecure http, would that be possible and if so where in the gui?
Thanks.

The third field is from a WLC running v7.4 not v7.2. I usually would install a 3rd party certificate, but what eles you can try is issue this command on from the CLI. It had issues working with certain code versions, but you might as well give it a try.
config network web-auth secureweb disable

Error while configuring apache FOP for printing

Dear All,
I have a requirement to print a report using custom layout.
I have installed apex 4.2 by configuring embedded PL/SQL gateway. I used the link:
http://docs.oracle.com/cd/E37097_01/doc/install.42/e35123/overview.htm#CJABBFIH
And for printing purpose I am installing apache FOP. I have installed oc4j in standalone mode. I followed the link:
http://www.oracle.com/technetwork/developer-tools/apex/application-express/configure-printing-093060.html
But after setting oc4jadmin password, I am getting following error

Seems like the Java EE container is looking for the Java compiler. Try installing the Java Development Kit (JDK) and respecify your JAVA_HOME accordingly. HTH.

LOGO in PDF file (Apache FOP)

Hi all...I'm using the Apache FOP PDF printing option with the jsp packaged in the AppEx 3.0.1 install. I would like to put a logo in the header of the generated PDF file. I made a compy of the default generic columns layout and added this to the header section in Page Template:

Could the fo block be in the wrong place in the document? I'm not very familiar with XSL-FO and may have just placed it wrong.
One other thing I just noticed. The webserver is actually using SSL, which on windows systems results in a pop-up about security. If I change the URL to https using the SSL port, I receive a message about security certificates.
Thanks,
Leigh
