Apex Listener and Apex .3.2.1

Does Apex Listener work with Apex 3.2.1? May be I missed it, I can't find any info in the document.

Short question, short answer: It does.
The documentation for the APEX Listener doesn't refer to any special APEX version. The fact that the APEX documents only name the APEX Listener from APEX 4.0 onwards is due to the APEX Listener not being available before that release.
We have it running with APEX instances from 3.1 onwards, but I assume you could use it even for older versions.

APEX Listener and EPG - strange behaviour

Hi
For some years, I've used EPG for APEX but have struggled with performance particularly as I can have up to 150 student developers using at any one time.
I do a fair amount of work using ORDImage and have successfully developed APEX applications to upload image files and display full-size and thumbnail images.
After upgrading to APEX 4.1 (from 4.0), I decided to install APEX Listener standalone.
Before I did so I checked that my applications still worked in 4.1 and they did.
However, just installing APEX Listener but not configuring it (yet) has meant that my image display in a report using a procedure based on wpg_docload.download_file( l_ordimage_image.source.localData ) no longer works in EPG - the images are not displayed.
Configuring APEX Listener and running the same application through that DOES display the images.
So this part of the application works under APEX Listener but not under EPG.
My application also allows users to upload images from APEX_APPLICATION_FILES using standard code. Under APEX Listener after uploading, I'm left with a blank page with a wwv_flow.accept URL although the image does indeed upload. Under EPG it works as expected and I get a success confirmation.
So this part of the application works under EPG but not under APEX Listener.
Has anyone else come across different behaviour depending on the mode of connection?
Thanks

Hi Brian,
it sounds like you have both EPG and APEX Listener running on the same machine, so your problem might result from a port conflict. Note that both services use TCP port 8080 as default.
At least a port conflict would explain the strange behaviour in your case, some things working on one web server and some on the other.
Some parts of your initial post hint to that direction, e.g.
However, just installing APEX Listener but not configuring it (yet) has meant that my image display in a report using a procedure based on >wpg_docload.download_file( l_ordimage_image.source.localData ) no longer works in EPG - the images are not displayed.... because the APEX Listener only interfere with the EPG if it is at least running on the same machine as your database and furthermore, if it is unconfigured in terms of ist database connection, a port conflict might be the only way it could cause anything like that.
However, if you are sure that's not the issue, please check if you see any error in the APEX Listener's log for the following action you performed:
My application also allows users to upload images from APEX_APPLICATION_FILES using standard code. Under APEX Listener after uploading, I'm left with a blank >page with a wwv_flow.accept URL although the image does indeed uploadIf you actually see just a blank screen, something very bad must have happened and you should see some kind of stack trace there.
For further investigations, if necessary, it would be helpful to know how you deployed or started your APEX Listener and which JDK version you use.
For the moment, I still think the port conflict is my best guess.
You could avoid it by either changing the port for EPG (I'd not recommend that if you have other users still using it) or by changing the port for your APEX Listener.

Apex Listener and Clustering - WebLogic Server

Has anybody worked with the apex listener on a clustered WebLogic environment with a load balancer? We are having lots of connection issues, and I am wondering if this could be part of the problem.
Thanks,

Apex Listener and EBS

Has anyone deployed Apex listener to work with EBS-R12 ? Did you deploy the war on the Application Server of EBS or did you deploy a new application server ?

I know exactly what you want, to embed the Apex listener servlet into the EBS OC4J, using autoconfig. I have done this before, but with my own servlet written from scratch, and it works very well. I had a go at integrating the the Apex listener servlet into an R12 instance a while back, and I actually got it to respond, but the URLs it was generating were not correct, so I gave up. I cannot remember the exact details, I got frustrated because I didn't have the time to wade through de-compiled source code to see what it was doing.
Here is the rough guide to getting a custom servlet embedded into the EBS R12 OC4J engine. You or somebody else could pick this one up, I don't have the time sorry.
Place your jar file in $JAVA_TOP (you may have to unzip it to get the class files usable by the JRE).
Navigate to the template directory.
cd $FND_TOP/admin/template
Create the "custom" directory if it does not already exist.
mkdir custom
If the file orion_web_xml_1013.tmp does not already exist in the "custom" directory then copy it in. Be careful not to overwrite an existing copy of this file or you may lose pre-existing customizations.
cp orion_web_xml_1013.tmp custom
Move into the custom directory and edit the custom template file.
cd custom
vi orion_web_xml_1013.tmp
Define your servlet: Paste the following lines just before the TCF alias (approximately line 162).
<servlet>
<servlet-name>myServlet</servlet-name>
<servlet-class>com.anything.myServlet</servlet-class>
</servlet>
Paste the following lines just before the TCF aliases (approximately line 950).
<servlet-mapping>
<servlet-name>myServlet</servlet-name>
<url-pattern>/myServlet/*</url-pattern>
</servlet-mapping>
4. Run Autoconfig
cd $ADMIN_SCRIPTS_HOME
adautocfg.sh
5. Bounce Apache
adapcctl.sh stop
adoacorectl.sh stop
adoacorectl.sh start
adapcctl.sh start
6. Test the Servlet
To test whether the servlet has been installed correctly, first get the value of profile option "Apps Servlet Agent".
Then enter the following URL in your browser:
<<value of profile option>>/myServlet/hello
Good luck,
Steve

APEX Listener and RAC

Is APEX Listener RAC-capable? Neither the Installation Guide nor the APEX RAC white paper provides information. Is there some experience installing APEX Listener within a Oracle 10.2 RAC environment?
What would be the advantage / disadvantage?

Hello,
as far as I know, you can use the thin driver to connect to RAC. If I don't remember this wrong, you should be able to configure the URL like this:
jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)
(ADDRESS=(PROTOCOL=TCP)(HOST=host1) (PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=host2) (PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=service)))What would you like to compare the RAC-Connection used by the APEX Listener with to outline advantages/disadvantages?
I think, the connection is not much different from the one you'd get when configuring a OHS that way. The EPG variant would be integrated in the RAC, but for fault tolerance you'd need some frontend server for node-failover anyway...

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!
Rob

Hi 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

Communication between TNS_Listener and Apex Listener

Dear all,
I how does the communication between TNS Listener, Apex Listener, and Apex? For some reason I got the following error from Apex listener:
Caused by: oracle.dbtools.rt.web.WebException: Unable to start the Universal Connection Pool: oracle.ucp.UniversalConnectionPoolException: Cannot get Connection from Datasource
Caused by: oracle.net.ns.NetException: Listener refused the connection with the following error:
ORA-12505, TNS:listener does not currently know of SID given in connect descriptorI truncated some of the Java object messages.
This occurred when I tried to connect to Apex. Then I can fix this by going to:
http://localhost:8080/apex/listenerConfigurethen, everything worked fine.
My listener.ora file:
LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = firefly.snowdrop.com)(PORT = 1521))
ADR_BASE_LISTENER = /usr/local/oracle
ADR_BASE_ORACLE_LISTENER = /usr/local/oraclemy tnsnames.ora file
INARA =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = firefly.snowdrop.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = inara.snowdrop.com)
)where inara is the instance name and firefly is the hostname.
Does the order of whether starting TNS Listener first or starting Apex Listener first matter?
Best regards,
Val

Hm, I'm not able to reproduce the error. There was one time when I started APEX Listener got:
java.net.BindException: Address already in use: 8080=com.sun.grizzly.http.SelectorThreadHandler@46d999aand when I did the netstat -a got:

There was one time netstat -a showed me this (this happened after I stopped Apex Listener, stopped TNS Listener, shutdown the database, started database, started TNS Listener, and started Apex Listener):

Apex Listener vs. Oracle Application Server... advantages?

Are there advantages to installing Apex Listener over using an existing Oracle Application Server instance to serve Apex applications?
We have an existing application server instance in production. Would introducing Apex Listener and the extra overhead be of any advantage?
Thanks in advance for your thoughts.

Hello "Portal Dude",
Are there advantages to installing Apex Listener over using an existing Oracle Application Server instance to serve Apex applications?APEX Listener introduces some additional features, such as Resource Templates, but lacks some others. Some people might want to migrate from OAS to another JEE Container that doesn't come along with a OHS/mod_plsql. Depending on the JEE Container, you could use AJP for load balancing, avoiding plain HTTP through a firewall, etc.
Would introducing Apex Listener and the extra overhead be of any advantage?The "extra overhead" may be smaller than you think. If you don't need the HTTP_Server component any longer, but can just deploy APEX Listener on the OC4J of your OAS, you might even save some bytes.
For several other aspects, there have been a few posts on that topic in the past:
{thread:id=1100122}
{thread:id=1555908}
{thread:id=1594158}
If there's anything you don't find in either the posts or the documentation, don't hesitate to ask.

APEX Listener for Extranet

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.
Andy

Hi 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...

Apex Listener Configuration Issue.

Hi there,
As I wanted to try the latest Restful services in apex 4.2, I decided to install Apex Listener 2.0. I downloaded the file and followed the steps as in the installation notes. As a pre-requisite, I configured the Restful services successfully in apex 4.2 along with Oracle 11g Express Edition. However, the installation of listener seems to be not compleated successfully with the following installation feed back.

Thank you Probodh for your quick help. I set the port 8080 to apex listener and it does not give that error now.
However, it still says "Default Database Connection not configured properly"
I gave the SID name as xe which is the default one, and that is the correct SID for my DB also.
Any possible mistakes in there?

Apex listener images folder issue

Hi expert,
I'm newbies in oracle apex listener and would like to know more about oracle apex listener from all the expertise.
My situation is like that i would like to install apex listener (standalone mode) in a server to browser apex application from another server with oracle database 11g and oracle apex development.
My installation step as below;
1. I copy images folder from database server apex\images folder to apex listener installation folder before i install apex listener (called "apexlistener").
2. Run cmd "java -Dapex.home=c:\apexlistener -Dapex.images=c:\apexlistener\images -Dapex.port=8585 -Dapex.erase -jar c:\apexlistener\apex.war" to install apex listener.
Just a question, if i amended oracle apex application in database server, should i need to copy the images folder again to apex listener server?
What is the main source in images folder used in oracle apex listener server?
My experience is i tried to copy images folder from database server A with apex application (in runtime mode) to apexlistener folder server B. And i configure the database connection to server c with same oracle apex application as well. I tried to browser oracle apex application in server c from server B. I found out my apex application is not running properly due to the javascript is not installed properly. I would like to ask, is the images files in apex listener server must same with apex application server?
Anyone have idea on automatically start apex listener when the server reboots?
How to run apex listener in backend?
Hope can get some idea and solution from all the expertise!
Thanks in advance!
Best regards,

Hi,
Too many questions, and too little input, for one post.
I'm newbies in oracle apex listener and would like to know more about oracle apex listener from all the expertise.My situation is like that i would like to install apex listener (standalone mode) in a server to browser apex application from another server with oracle database 11g and oracle apex development.
My installation step as below;
1. I copy images folder from database server apex\images folder to apex listener installation folder before i install apex listener (called "apexlistener").
2. Run cmd "java -Dapex.home=c:\apexlistener -Dapex.images=c:\apexlistener\images -Dapex.port=8585 -Dapex.erase -jar c:\apexlistener\apex.war" to install apex listener.
Just a question, if i amended oracle apex application in database server, should i need to copy the images folder again to apex listener server?

The images folder has a relation with the Apex Version installed on the database, not with the applications in the Apex.
Depends on what you mean by amending applications. If you add custom CSS, JS ,etc to the application , and are not uploading the files to WORKSPACE_IMAGES, then you need to copy the external files to the images folder. But not copy it all over again.
If no custom files then no need to copy the images folder.

The images folder, what else?

As stated earlier, the contents of the images (/i/) folder are related to the Apex Version. If your two db servers have different versions of Apex then the same images folder will not work with both. It will work with only one, the one that has the Apex Version compatible with the images folder.

How to suggest without knowing OS?
You can write a batch file that runs on bootup to achieve this.

What is backend? Do you means background or as a service?

Report Printing: APEX 4.01 - APEX Listener - WebLogic 10.3.3

We have some report printing issues...
Our configuration is APEX 4.01 using the APEX Listener with WebLogic 10.3.3.
The first issue is that under "Print Attributes" the following is listed in red under "Printing":
"Report printing is currently not available, there is no print server configured."
The second one is that we need to print pdf format and I have not found a solution for doing this with the APEX Listener and WebLogic. I saw that the FOP solution for the APEX Listener didn't make it into the current release... Is there any way to do pdf type reports with the current APEX listener technology?
The third issue is that in the demo app when running a report there is a "Error loading file:" type error with "FLOW_FLASH_CHART" and apex_util.flash as part of the url.
Any help would be appreciated...
Thanks!
- Scott

I deployed in WebLogic the fop.war that came with APEX 4.0.1 and it got rid of the error message, but when I tried to download a report as pdf, I got an error saying it was corrupted or invalid. I downloaded the file it produced and opened it in a text editor. It was a small html type file with the following URL:
ORA-20001: The printing engine could not be reached because either the URL specified is incorrect or a proxy URL needs to be specified.
When I go to the URL that I think it should be going to based on what I put into Instance settings> Report Printing, I get:

How to set encoding in Apex Listener

I have a problem conversion characters when using Apex listener
The problem occurs in two different configurations:
1. APEX Listener 2.0 running on GlassFish Server Open Source Edition 4.0 Oracle Database 11g Release 11.2.0.3.0 (NLS_LANGUAGE: AMERICAN, NLS_CHARACTERSET: AL32UTF8)
2 . APEX Listener 2.0 running in standalone mode Oracle Database 10g Express Edition Release 10.2.0.1.0 (NLS_LANGUAGE: AMERICAN, NLS_CHARACTERSET: AL32UTF8)
to demonstrate the problem I created a restful service, which is in the GET method returns the result of the query :
select: p_param as "result" from dual
parameter : p_param transmitted via http header
parameter : p_param set to 'sample data дф ' , the last two characters - Cyrillic
Http Request is as follows:
GET http://xxx.xx.xxx.xxx:8080/apex/encode HTTP/1.1
Accept-Encoding: gzip, deflate
param: sample data дф
Host: xxx.xx.xxx.xxx: 8080
Connection: Keep-Alive
User-Agent: Apache-HttpClient/4.1.1 (java 1.5)
in both cases, the return value - <result> sample data 4D </ result>
I could not find documentation on how to avoid re-encoding?
regards.

With a WE8MSWIN1252 (or comparable charset) database, fronted by APEX listener, and the absense of NVARCHAR2 support in APEX, is there an option to build an APEX application supporting UTF-8 characters anyway, without converting the whole database to UTF-8?
As "Application Builder User’s Guide" is quite tight-lipped when it comes to UTF-8 support, can somebody recommend an APEX FAQ concerning UTF-8 support in APEX?
Thanks and regards, Tom
