  could someone help me
  
  FYI - I can configure apex listener 1.1.4 and Glassfish 3.1.2 no problem
  
  Thank you

  This is one of them. There are several option.

  Take a look at:

  java -jar apex.war help 
  

  That will show you all the options.

  Which is the main:

  java -jar apex.war setup --database test
  

  Now keep in mind, this will change your WAR file. After its deployment, the parameters are in XML files. I highly recommend that you configure a location of configuration before you deploy the WAR file. It will make your life much simpler and more predictable.

  Hi Andy,.

  ApexListener has no rewriting engine.
  What we have done is we have an Apache (not ESS) server in front of the J2EE container running ApexListener.
  URL rewriting is done in the Apache. Your current rules of OSH should be copy/paste in the Apache server.

• How can I disable only restful service? On Apex listener

  Hi all:

  For security reasons, I want to turn off the data service based in some of the listener apex server and activate the application only service. How can I do?

  Support gives the solution:

  How to disable the restful services is NOT to configure pools of connections AL and RT in the ADR/Rest Data Services. (APEX Listener).
  Remove or rename the files apex_rt.xml and apex_al.xml available in the configuration (conf) configured against ADR directory used by these bodies / the listener of the APEX.
  This way ADR / the APEX listener will not be able to deliver the REST requests to the database and return 404 to the end user

• problems in the deployment of the apex for tomcat listener

  Hello
  
  I'm looking for a set of (almost infallible) instructions for installation of the auditor of the apex to tomcat.
  
  So far I managed to deploy the listener and tomcat told me that the listener is configured.
  
  I realize I have to copy the images to the directory of tomcat (I cancelled trying to get going again).
  
  
  Then the images go in tomcat/root/i
  
  I suppose we rename the directory images on i. so what was the root/tomcat/images become i/root/tomcat
  
  I see that the apex war has been deployed.
  
  Where's the apex_config.xml?
  are we supposed to run the sample_capture.sql script?
  
  When I launch http://localhost: 8080/apex/ListenerConfigure I get message now:
  
  "The listener of the APEX is already configured. Please log on as an administrator to access the listener Administration APEX. »
  
  When I launch http://localhost: 8080/apex/ListenerAdmin I am invited for the user name and password.
  
  If I put in apexAdmin as username and admin as the password, the values are not accepted.
  Finally (3rd attempt) I get "this request requires HTTP authentication.
  
  There is a similar problem with ApexStatus.
  
  Finally if I type http://localhost: 8080/apex/I get required url http://localhost: 8080/apex / is not allowed.
  
  
  Is there a step by step guide to install listener apex under tomcat?

  I just posted a new version. That should solve the problem. In tomcat http://localhost/apex/ had a problem where if you don't http://localhost/apex/apex it would work. Basically, the default page worked in tomcat.

  Previous stages of the installation went well.

  How do you use ADR/APEX listener? Autonomous/deployed on Java EE server?

  Want to host RESTful web services on your instance APEX?

  Looking at the error you found, it is because:

  During the installation of the ADR, he asked three databases users? : APEX_PUBLIC_USER, APEX_LISTENER and APEX_REST_PUBLIC_USER.

  Whose APEX_PUBLIC_USER is required for the operation of the Applications Oracle APEX. APEX_LISTENER (which corresponds to the configuration of apex_al) and APEX_REST_PUBLIC_USER (which corresponds to the apex_rt configuration) in ADR are required for the accommodation of RESTful services.

  The problem, I think it's that you haven't configured the RESTful services before installing ADR where the APEX_LISTENER and the APEX_REST_PUBLIC_USER does not exist and so the configuration of the ADR fails.

  It is fine if you do not configure the RESTful services (just want to use Oracle APEX), but when the ADR facility you should ignore configuration APEX_LISTENER and APEX_REST_PUBLIC_USER accounts.

  Moreover, I think that you use EA(Early Adopter) version of ADR version 3.0 of knowing, but I think you should go for the stable version of ADR version 2.0.10 Viz.

  The ADR 3.0 configuration is more advanced (complex bit) than the 2.0 because it contains information about 5 database users (i.e., APEX_PUBLIC_USER, APEX_LISTENER, APEX_REST_PUBLIC_USER, ORDS_METADATA and ORDS_PUBLIC_USER).

  Finally, I think you want the instance Oracle APEX for purposes of personal training, using Gateway (EPG) of embedded PL/SQL would be sufficient now as suggested by fac586 here: Re: getting started with APEX after download

  Suggestion: You should post data Services Oracle REMAINS related matters to the appropriate i.e. forum ADR, SODA & JSON in the database.

  Reference:

  • For ADR 2.0 installation guide
  • For ADR 3.0 installation guide
  • Installation of Oracle APEX, with EPG guide.

  I hope this helps!

• Problem using a folder next to the East on UNIX Ubuntu 10.4 with APEX listener

  Hi Forum,
  
  We have APEX 4.1 installed on Ubuntu 10.4 with the latest version of the APEX-listener.
  
  We want to achieve is that we are able to collect our Javascript extensions and css next to the folder is in a folder of our own.
  Problem now is UNIX, this doesn't seem to be possible, because we are unable to load any resource of this folder. The only solution we could come up with is to place a symbolic link in the/i/folder-pointing to the directory we want to include.
  The folder we want to include got 777 to exclude any potential problems of access to in UNIX
  
  Under Windows, this doesn't seem to be the case.
  
  If someone had a similar problem or is able to give advice on how to fix this?
  
  Thank you
  
  Jürgen

  Hi Jürgen,

  docroot
  -foo
  -J' I

  This does not work in stand-alone mode, the integrated nature fixed contexts (including + / i + and + / apex +) without the chance to bring custom contexts.
  It will run in GlassFish/Tomcat, if you deploy content correctly. You can do this by creating a war file that carries your files, but I wouldn't recommend it has static content more convenient ways.
  Tomcat has for example a context ROOT when running on a default configuration. This context can be used for static content similar to a simple HTTP server host, for example when using the htdocs of the Apache HTTP server as docroot. So you could simply copy your directory foo in the context of the ROOT and should be able to access the content using http://yourtomcathost:yourtomcatport/foo/file name .
  GlassFish is a concept similar to this: each domain has a docroot directory. As explained for Tomcat, you can simply create or copy your directory foo it so that it is available for your customers.

  If this does not work, you have a general problem with your GlassFish/Tomcat configuration, like the docroot has nothing to do with the earpiece of the APEX. I have just retestet with fees GlassFish/Tomcat on Ubuntu 8.04 LTS (Server Edition) as follows:
  1 download the http://glassfish.java.net/ zip or Tomcat mirror packages respectively.
  2 unzip the package
  3. create the directory 'foo' docroot (for GlassFish) and ROOT (for Tomcat)
  4. create the file 'bar' in 'foo '.
  5. start the server instance
  6 use a client remote access http://mybox:8080/foo/bar.txt and got the file.

  How did you install your GlassFish/Tomcat on your Ubuntu?
  Whatever it is, if you tried the docroot/ROOT approach and doesn't, you can always try the war file deployment. Maybe your GlassFish/Tomcat instance has disabled the docroot/ROOT context for security reasons.

  Note that you can have both, that is, you cannot use the war with framework file + / foo + and have always a + / foo + subdirectory in your docroot/ROOT.

• APEX listener 2.0.1 does not start when the system starts

  APEX listener 2.0.1

  Linux RHEL 6.3

  GlassFish 3.1.0

  -------------------------

  After the reboot of my Linux server with the configuration above, the listener of the APEX is broken and must be restarted by GlassFish. This may be the cause?  How can I get the APEX via GlassFish listener to restart the power-up system?

  NOTE: I don't have this problem when you use APEX listener 1.4 to the same server GlassFish.

  Thank you.

  Found the problem.  chkconfig was before the database has increased the age GlassFish and running.  Chkconfig changes of the parameters in the startup scripts. Works very well.

• Get the blank Page using Weblogic and Apex listener v2

  Greetings,
  
  So I thought I would upgrade to the new version of the listener at the same time, I'm moving my current listeners of the apex (version 1.0.2.238.15.24) to a new server. The version of the new listener, I try to use is 2.0.0.354.17.05.
  
  I need to set up several headphones on the new server to point to different environments. I managed to successfully install the new listening port for one of my environments and everything works fine. However when I try to install the listener once I get a blank page when I try to put in place the Apex.
  
  I created two areas Weblogic (v 10.3.3), one for each listener. Here is how they are configured:
  
  This earphone works.

  DEV1
  Domain Name:     APEXA
  Host Name:     mars
  Port Number     7023
  Database Host:     mars
  Database Name:     SID1
  APEX Version:     4.1.0.00.32

  This listener DOES NOT work.

  DEV2
  Domain Name:     APEXB
  Host Name:     mars
  Port Number     7053
  Database Host:     venus
  Database Name:     SID2
  APEX Version:     4.1.0.00.32

  I am trying to access the second listener by entering this url:

  http://mars.xyz.com:7053/apex

  and that value is returned

  http://mars.xyz.com:7053/apex/f?p=4550:1:684042141256623

  Since the number of app, the page number, the session information is there, I guess that is what makes the database and is processed by the Apex. The problem is that the returned page is empty. The source of the actual page is:
  
  

  <html>
  <head>
  </head>
  <body>
  <pre></pre>
  </body>
  </html>

  I checked that images are accessible by entering:
  http://Mars.xyz.com:7053/i/apex_version.txt
  
  This is what is returned:
  Application Express Version: 4.1
  
  I don't know how to debug this problem. Any help would be appreciated.
  
  Thank you
  
  Larry

  You have configured different configuration for Auditors 2 directories? If only they would use the same config files and which would give conflicts.
  You can also configure the two summits on the same listening port, each accessible with a different URL prefix.
  And if the second database is always 10g, then you might hit a bug (Apex listener 2.0 does not work against 10g DB).

• Deployment of the APEX, for commercial purposes

  Dear Experts,
  
  I build application APEX for the customer. I have two options for deployment.
  (1) to prepare the necessary infrastructure for a dedicated server in the client's site?
  2) host in one of the APEX hosting companies?
  
  What are the short-term and long-term benefits and disadvantages of each option from the commercial point of view?
  
  Best regards

  Hello

  the error and the effect that you do not see the images is probably caused by a typo or another error in the path that you entered for the static content at the first time you started the independent auditor. Maybe you just press enter in the configuration dialog box.
  Search for the apex.properties file, which is usually stored in/tmp/apex and fix the value for apex.images parameter points to a directory where your pictures of the APEX are stored.
  If you do not, download the release of APEX belonging to your installation and unzip the installation package. The images directory content in there, that's what you'll need. Copy it in any place, for example/opt/oracle/products/apex/images and configure the listener APEX to use this path.

• How to change the directory of apex - listener.xml using container startup options?

  The option proposed in the thread Re: change the URL of earphone APEX (second post by Udo) seems attractive, but being not not Glassfish pro, I do not know how.
  Anyone can indicate in which succession of menus Glassfish should I go to refer - Dconfig_dir =... parameter?
  
  I run Apex listener on Glassfish 3.1 1.1
  
  Igor

  Hello Igor.

  the setting -Dconfig_dir = is an option for the JVM, used similar to a shell environment setting.
  You can set this parameter to GlassFish by editing the startserv.bat or shell startserv script, depending on the OS you are using.
  Note that you can use any name, as config_rep is a name arbitrarily chosen for the parameter that I presented for the config file.

• Cocoon with fop_post deployed to the United Nations for APEX

  I have APEX through OAS, so I have deployed Cocoon with fop_post with the Organization as well. I put the memory for the container to-Xms512m-Xmx512m. When I put the output to Word, Excel or HTML format, I get a blank document. When I put the output in PDF format, I get an error on trying to open the pdf file. The pdf is size of 0 bytes. Adobe error is
  
  Acrobat cannot open 'tasklist.pdf' because it is not a type of supported file or because the file has been damaged (for example, it was sent as an attachment to e-mail and has not been correctly decoded).

  I use OAS 10.1.2.2 and APEX 3.1.2.00.02.
  
  What Miss me?

  Kris,

  Your error messages, it seems that something is wrong with your model, the model is not provided, or do not match the names of arguments. The apex_fop.jsp that I was referencing is actually the implementation of Apache FOP based we ship with APEX, i.e. you can use it instead of your approach to Cocoon. Oracle offers both supported renderers impression that work with APEX, a BI Publishers, which must be purchased separately, and the other is Apache FOP, which we ship free for free with APEX. Carl had posted on the use of Cocoon as another alternative to illustrate how visitors have the choice of using other third-party renderer FOP engines. I have not tried the application Cocoon myself yet, but if you want to try the apex_fop.jsp (which is part of the fop.war file in the directory setup APEX), please take a look at the following configuration guide, which applies to the BI Publisher and Apache FOP:
