APEX Listener as a replacement for modplsql ?
Will APEX Listener ever be, or is it able to be now, a replacement for modplsql driven applications that are not APEX. It seems that it already takes care of everything needed to be a full scale modplsql replacement... In all honesty looking to see if it is possible to reduce the future licensing load on some of my clients if they wanted to build more redundancy into their front-end web applications. They wouldn't be reducing what they pay, as they are still in for the Forms installs in app server, but they are inhibited on their redundancy growth outward since adding new licenses to cover these new servers would be cost prohibitive. This is mainly a third-party product (SGHE's Self-Service Banner) that is driven off of modplsql, so rewrite isn't an option.
Thanks for your input,
-Richard
As of the last EA version, it depends on which modplsql features your application uses. The main modplsql features that are not yet supported are:
Basic database authentication - The listener must be configured with a single username and password and cannot dynamically change the database connection at run time.
Multiple DADS - Each listener is configured for one and only one database connection. However, there is a way to install multiple copies of the listener, and configure each for a different database connection.
Dynamic parameter passing - There must be a one to one relationship between fields on an HTML form (or query string variables in the URL) and the non-defaulted parameters of the called procedure. Name and Value arrays, with the "!" before the procedure name in the URL are not supported.
CGI environment variables in the DAD.
Oracle MAY support some or all of these features in the production version, or in some future version. We can probably influence this by telling Oracle what we want - but no guarantees. Kris Rice tells me that the APEX Listener was written to be extendable, so once Oracle gives us some documentation of how to extend it, some enterprising programmer may add some of these features as an extension.

We are planing to use APEX with APEX listener in production site for better security .
Under this circumstances, do we still need to install XMLDB .
If it is, could you please let me know what functionality of XMLDB is required when we are not in EPG mode.Hi there,
If you do not have XDB installed, then the APEX component will be invalid. Essentially, it is an unsupported installation. If you ever need to call Oracle Support, the first thing they'll ask you to do is make the component valid (by installing XDB).
XDB is used in a number of places in APEX - as an XMLTYPE in collections, parsing of Web Service results, XML data loading and unloading, XLIFF translation file parsing, probably a few more areas that I'm not recalling now.
I hope this helps.

Interactive Reports not working with APEX listener
Hi,
I have posted this question APEX listener forum couple of weeks ago but very few responses.
If any one from here can help then it would be great.
Interactive Reports not working with APEX listener
Best Regards,
BaigSorry for late response.
It was a firewall issue -
Hi,
We've been using Oracle HTTP Server (Apache) for my APEX connections. We're new to APEX Listener and have no knowledge about it.
1. First of all, is Oracle GlassFish Server free? Does it require license cost per CPU like Oracle Weblogic does?
2. We currently have an extranet box that runs Oracle HTTP (actually Oracle HTTP inside Oracle AS 9i). If we need to use APEX Listener, should we install the J2EE Container (Oracle GlassFish) with APEX Listener inside our "Intranet" and only the Oracle HTTP Server in our extranet server? I'm confused about the appropriate method for "extranet" environment.
Thanks.
AndyHi Andy,
1. First of all, is Oracle GlassFish Server free? Does it require license cost per CPU like Oracle Weblogic does?As Prabodh already mentioned, there exist two different editions of GlassFish by now: The officially supported Oracle GlassFish Server (with license costs) and GlassFish Server Open Source Edition (free). While you can run APEX Listener on both of these JEE Containers, you will not get any support through MOS when using the latter one.
2. We currently have an extranet box that runs Oracle HTTP (actually Oracle HTTP inside Oracle AS 9i). If we need to use APEX Listener, should we install the J2EE Container (Oracle GlassFish) with APEX Listener inside our "Intranet" and only the Oracle HTTP Server in our extranet server? I'm confused about the appropriate method for "extranet" environment.I'm not sure if this has become clear yet: You don't actually need OHS for APEX if you start using APEX Listener. You can deploy APEX Listener to a GlassFish on your extranet server. It'll connect to the database listener of your APEX instance using JDBC like OHS/mod_plsql did before.
Of course, you could think about adding a security layer to your database by hiding it's listening endpoint from your extranet. To do that, you could deploy APEX Listener in your internal network and let OHS (or a "plain" Apache HTTPD) on your extranet box act as a proxy. That way, you'll have only HTTP or AJP traffic through your firewall (or whatever is in between your internal network and your extranet), but you could close your database port. In that case, it also could be a good idea to let the proxy serve the static contents for APEX ("images") on your extranet box for less traffic on the link between internal network and extranet and especially for better response times towards extranet clients. Of course, if you have internal users for that instance as well, you'll want to deploy the images to the GlassFish as well...

How do you change the port number for Apex Listener V2?
I'm running Apex listener V2 in standalone mode on Linux. I want to change the port number of the apex listener V2 (e.g 80 to 8080). How do I do that without re-installing the whole listener again?
thanks in advance
PaulPHi PPlatt,
You can modify your_listener_home_directory/apex/apex.properties
http.port=8080
Stop & restart listener.

APEX LISTENER Install troubleshooting
Hi, I need help.. :-)
Default Database connection not configured properly
What I have done:
ALTER USER APEX_LISTENER ACCOUNT UNLOCK;
ALTER USER APEX_PUBLIC_USER ACCOUNT UNLOCK;
ALTER USER APEX_REST_PUBLIC_USER ACCOUNT UNLOCK;
connect APEX_LISTENER/mypasswd1
connect APEX_PUBLIC_USER/mypasswd2
connect APEX_REST_PUBLIC_USER/mypasswd1
Check default.xml
password: replaced encrypted one with clear text one for APEX_PUBLIC_USER to ensure it is correct
even tried APEX_LISTENER password just incase
Is there a simple JDBC test to see if it connects? it is APEX_PUBLIC_USER who is connecting isn't it?

You can use SQLPLUS to make sure you have the correct password.
After that, it is the SERVER, PORT, SID/SERVICE in the APEX listener you need to confirm.
You can TNSPING to confirm you have the correct selections for those.
You can always re-run the java -jar apex.war setup command to all of the basic settings.
The reason I mention that is because if you modify the settings manually - we need to ask "which file?" because there is the default and the database specific one too.
Try making a request to the service in standalone mode and you should get a terminal output (the window stays open) with a more detailed error. I would guess there will be an ORA-12514, TNS listener does not currently know of service requested in descriptor or something similar that will give you the "debug" information you are looking for.

Apex Listener commercial license
Hello,
I created applications with Apex and I'm about to install Apex on an other database.
I 'll maybe choose Apex Listener but I don't know if there is a commercial license for it: would my customers have to pay to use an apex application that runs with Apex Listener ??
Thanks.
FannyIf you use the ORACLE HTTP server (Apache with modplsql), it's free with the database license.
If you use the APEX Listener, you need an App Server. The App Server requires a License.
For APEX, it's licensed with the Database for all version , Standard One, Standard, Enterprise, Express.

APEX Listener EA2 Standalone CLOB error
I'm testing the APEX Listener EA2 release in Standalone mode on CentOS against Oracle XE.
My RESTful service calls use the Media Resource type to return a CLOB that I format myself inside a function:
select 'application/json', my_function_that_returns_json_in_a_clob from dual
In the EA2 release, this is generating an error if the function returns more than 4000 bytes (works with 4000, fails with 4001). It is as though the function is getting cast as a varchar2 somewhere. I verified that the function will correctly return a large result to other sources (dbms_output, for instance).
The APEX Listener Log reports the error as:
oracle.dbtools.rt.web.HttpEndpointBase restfulServices
SEVERE: ORA-22922: nonexistent LOB value
Here's a Test Case:
create or replace function test_size(p_cnt in integer) return clob
is
l_clob clob;
begin
for i in 1..p_cnt loop
l_clob:=l_clob||'a';
end loop;
return l_clob;
end;
Then create a RESTful service call:
Method: "GET"
Source Type: "Media Resource"
Source: select 'application/json', test_size(4001) from dual
Thanks,
TimThanks for your thorough reply!
Unfortunately, your workaround doesn't fix the problem with EA2. It encounters the 4000 character limit as well.
I understand your advice regarding using the QUERY type. I chose the Media Resource strategy for two main reasons:
1. These services calls are for our mobile developers. Because they use some predefined frameworks for managing data that comes to the mobile app, they wanted the json to distinguish between data sets (rather than every data set being called "items"). I am able to format the json in such a way that it doesn't confuse their code. Is there another way to customize the format of the default json created by the QUERY type?
2. I need to conduct some other business as part of the call. For instance, the service passes in a user's credentials which I use to authenticate and then retrieve the appropriate results based on who they are. Currently, I have stored procedures that authenticate APEX users or LDAP users.
Perhaps old habits die hard, but I find that if I just do all of this myself in a stored function, I have all of the control I need. If you have other recommended strategies, I'm all ears.
Thanks!

Apex listener images deployement
Hi
I installed the APEX listener recently. I have a question. Can I deploy the images in a different way other than jar them and then deploy to WLS. I have a lot of custom images/javascripts reside under the /i/ virtual path (e.g. /i/extjs). The images and javascripts change frequently. I guess that every time this happens I have to create a new i.war and redeploy which is not so convenient. Is there any other way to do that (e.g. copy them directly to a directory as I was doing with OHS/modplsql)
Thanx
GeorgeHi George,
you could do this by locating the directory where the WLS has unpacked the deployment to. But the more I think about this, the more I think you shouldn't do that, because staging etc. makes this very complex again.
Instead of deploying the images as war file, you could add a virutal directory mapping, which is far easier.
It should be possible to do that in the weblogic.xml of the apex.war (unpack the war, edit the file, repack the war, similar to what you'll do if you edit the web.xml, e.g. to change to config.dir parameter). See the [url http://download.oracle.com/docs/cd/E13222_01/wls/docs81/webapp/weblogic_xml.html#1039396]corresponding part of the WLS documentation for details on that parmaeter. The result could be a weblogic.xml as follows
<weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/weblogic-web-app">
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
<virtual-directory-mapping>
<local-path>/opt/oracle/apex/images</local-path>
<url-pattern>/i/*</url-pattern>
</virtual-directory-mapping>
</weblogic-web-app>if your images are stored in */opt/oracle/apex/images* .
Not that this can cause node specific dependencies if you have a clustered WLS, and that you'll have to undeploy the i-application before you can redeploy the apex.war.

APEX Listener 1.1.4 install issue with listener configuration
Oracle XE 11gR2
APEX 4.1.1
APEX Listener 1.1.4
Glassfish 3.0.1
=============
Installing APEX Listener 1.1.4 to replace APEX Listener 1.0.2. Deployed apex.war file but now:
(1) http://10.10.1.111:8080/apex/listenerConfigure web page comes up but with no frames/windows rendered, as if it can not find images. Still I can enter data into fields. Wonder why the graphics/images are missing when page is rendered.
(2) after entering Listener connection information for user APEX_PUBLIC_USER, I get "Permission denied". I can connect via SQL Developer to APEX_PUBLIC_USER with same credentials. I was able to connect before with previous APEX Listener.
Any ideas?Hi,
(1) http://10.10.1.111:8080/apex/listenerConfigure web page comes up but with no frames/windows rendered, as if it can not find images.
You either have to clean your browser cache or your browser is too old/not capable of rendering the css of APEX Listener correctly.
(2) after entering Listener connection information for user APEX_PUBLIC_USER, I get "Permission denied". "Permission denied" doesn't sound an issue with your database configuration. Do you have anything in your APEX Listeners log (probably within your GFs server.log) for that issue?
But perhaps the error disappears as soon as you also get a proper configuration page.

Any help much appreciatedFurther to the above post, I thought I'd simplify my Apex Listener install just to see if I can connect to it via SQL Developer
So downloaded the latest version 2.0.8 and decided to configure and run the Listener on my pc whilst still connecting to the same database.
Operating system : Window 7 Pro 64 bit
Oracle Apex Listener 2.0.8
Java(TM) SE Runtime Environment (build 1.7.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)
Went through the configuration as above, once started I tried again to access the listener via SQL Developer. This time I received this output from the listener:

I am assuming this must be part of the problem I am seeing this the Weblogic deployment in my original post.
Does anyone have any suggestions on how best to tackle this?

Hi everybody!
I set up my Apex Listener in a Standalone Mode
How can I set up my URL with my words such as: http:/localhost:8585/myapplication/f?.......
replace for the default URL: http:/localhost:8585/apex/f?.......
I don't know where my DAD is, and how many steps should I do to complete this changes?
And how about
http://localhost:8585/apex" or "http://localhost:8585/apex/apex_admin?
Thanks for any help.Hi,
the APEX Listener has fixed (hard coded) contexts in Standalone Mode, so you can't do that. Either deploy the war file to a regular JEE server where you can choose the context, or put a HTTP (reverse) proxy in front to do the switch for you.
Note that Standalone Mode is not intended to be used for productive deployments, but for testing and development purposes only.

APEX Listener with APEX 3.0 on 11gR2
Yes, I am crazy.
We have many many APEX applications in APEX 3.0 running on a 10.2.0.4 database that needs desperately to be upgraded. As a test, I've set up a clean 11gR2 database and copied the production APEX database into it via datapump. I set up APEX Listener, as I don't have any OAS sitting around and the EPG doesn't seem to be supported for APEX 3.0... the Listener doesn't say one way or the other.
When trying to log in, I get the login page, but it tries to reference files such as apex_get_3_1.js while I only have files such as htmldb_get.js in my images directory in production. I noticed it is looking for what appears to be 3.1 files instead of 3.0 files... which concerns me.
The APEX listener appears to be more than just a Java PL/SQL gateway.
Is there a minimum version of APEX the APEX Listener supports?
Interested in pointers!
RobHi Rob,
Yes, I am crazy.Why would that be? ;)
We have many many APEX applications in APEX 3.0 running on a 10.2.0.4 database that needs desperately to be upgraded. As a test, I've set up a clean 11gR2 database and copied the production APEX database into it via datapump. I set up APEX Listener, as I don't have any OAS sitting around and the EPG doesn't seem to be supported for APEX 3.0... the Listener doesn't say one way or the other.APEX 3.0 is supprted by EPG. See the [url http://docs.oracle.com/cd/B32472_01/doc/install.300/b32468/post_inst.htm#CHDBEJDA]APEX 3.0 Installation Guide for details.
APEX Listener is capable of hosting APEX 3.0 as well, though APEX 3.0 wasn't supported anymore when APEX Listener was initially released. The current APEX release at that time was 4.0, so this would be the first version to be known as really stable, whereas you won't get any support for older releases anymore. From personal experience I know that there are now issues with APEX 3.1 and APEX Listener, so it'll probably also work with 3.0.
Concerning your database release, the minimum for APEX Listener is 10.2.0.3, so you're definetly safe on that part, though I'd recommend to upgrade as regular support for 10.2 databases ended.
When trying to log in, I get the login page, but it tries to reference files such as apex_get_3_1.js while I only have files such as htmldb_get.js in my images directory in production. I noticed it is looking for what appears to be 3.1 files instead of 3.0 files... which concerns me.This indicates that your APEX would actually be a 3.1 and you should update you images directory.
The APEX listener appears to be more than just a Java PL/SQL gateway.It is, but this has nothing to do with your 3.1 JS files, if this is why you stated this.
Is there a minimum version of APEX the APEX Listener supports?As mentioned above, 4.0 would be a safe approach, but 3.1 will definetly work, 3.0 probably will as well. I'd recommend you find out which APEX version is actually installed on your database before you consider any upgrade operations. Run the following query as privileged user:
SELECT comp_name, version, status
FROM dba_registry
WHERE comp_id = 'APEX';-Udo
