Problem setting up APEX 4 with WebLogic and Oracle XE

I'm am trying to install and test Application Express 4 (latest version) on a brand new installation of Oracle WebLogic Server and Oracle XE.
I have followed the Installation Guide for APEX and have successfully installed all tables and scripts into my Oracle XE schema and am able to connect to the Application Express Workspace login page (http://localhost:8080/apex) but am not able to log in. All styles and images are missing.
I have followed the steps in the Application Express Listener Guide to install the Listener to my WebLogic deployments and have my i.war and apex.war files deployed but these apparently are not working. When I go to my WebLogic server and view the /apex/ListenerConfigure page I can see the page but get an HTTP 404 "Page Not Found" error and appears to be looking for the WLS's apex/apex directory.
Note: My Oracle XE / APEX setup is on a separate server than my WebLogic server.
Also, I see the APEX Listener file (apex-confix.xml) from the install zip file but I don't believe it is being used anywhere, as the documentation never told me what to do with it.
Any help would be awesome. Let me know what I can provide that I haven't. Thanks!

Thank you, I was able to use what you said as well as this information here: Installing Apex 4 on Oracle XE: Almost there, but no cigar yet!
Thank you for the help :)

Hibernate OR EclipseLink...Which is best with Weblogic and Oracle DB?

Hi All,
In my company, we are using Oracle DB and Weblogic application server. So in the process to upgrade or switch to new ORM, we shortlisted two options - Hibernate and EclipseLink.
I gathered following summary regarding both ORMs -
Hibernate:
1.     When you need to train people, like we are going to do next week – most of the companies have Hibernate experts.
2.     When you hire new developers, most of them come with specific Hibernate experience.
3.     When you need to consult with experts, both in the internet or consultants, you have LOTS of options. Endless forums and communities all regarding Hibernate.
4.     Hibernate is an open source which has a huge community. This means that it will be improved all the time and will push the ORM market forward.
5.     Hibernate is an open source which means you have the code to handle, and in case needed, fit it to your needs.
6.     There are lots of plugins to Hibernate, such as validations tool, audit tools, etc. These becomes standard as well and dismiss you from impl. things yourself.
7.     One most important thing with ORM tool, is to configure it according to your application’s needs. Usually the default setting doesn’t fit to your needs.
For that sake, when the market has a huge experience with the tool’s configuration, and lots of experts (see point 1 and 3) – most of chances you will find similar cases and
lots of knowledge about how to configure the tool and thus – your application.
EclipseLink:
1. Fully supported by Oracle. Hibernate no. In case of pb, it could be cumbersome to prove that it is a pure Weblogic one. Concretely, we will have to prove it (waste of time and complexity).
2. Eclipse link is developed by Oracle and the preferred ORM in the Weblogic /Oracle DB world.
3. Even if at a certain time EclipseLink was a bit late compared to Hibernate (feature), EclipseLink evolved very fast and we can consider now that they close the gap.
4. No additional fee as soon as you have Weblogic license. You will need to pays additional fee if you want some professional support on Hibernate.
5. We are currently relying on Hibernate for our legacy offer and are facing pb in second level cache (JGroups). Today, we are riding off this part!. Consequences are limitation in clustering approach (perf)
6. On EclipseLink side we do succeed to manage first and second level cache in a clustering approach.
7. Indeed Hibernate is open source, so you can imagine handling it. In reality, the code is so complex that it is nearly impossible to modify it. Moreover as it is LGPL, you need to feedback all the modified sources to the community systematically.
8. All tests performed by Oracle concerning Weblogic are using EclipseLink. Moreover, Oracle says that some specific optimizations are done to manage Oracle DB.
9. Hibernate comes from JBoss community.
Right now we are preferring Hibernate but there are concerns/reasons like EclipseLink developed by Oracle and preferred ORM in Webogic/ Oracle DB world (compatibility of ORM with DB and App. server), support comparison with both ORM, which are preventing to finalize the decision.
Please help me with you views and opinions and share you experience with us so that we can make a perfect decision.
If you want you can also reply to me @ [email protected].
Thanks.

The way the ORMs are designed, integration with application servers are relatively simple, and all provides the same features. Also since WebLogic have been around for a while, all ORMs are all well tested in this configuration.
Hibernate has lot more users, and is likely very often used with Oracle DB, so you can expect not much bug against Oracle DB, maybe even less bug than EclipseLink, which is not much used. EclipseLink does provide support for some esoteric Oracle DB features like hierarchical and flashback queries.
OpenJPA and DataNucleus are also JPA compliant. It’s likely that Open JPA has a higher user base than EclipseLink, so less unknown bugs.
Oracle paying support is well known to be a bad joke. It’s a negative return to use this channel, even if they would be free. So in reality, you end up to use the open (free) forum to get support.
What’s was lacking with Hibernate before is Dynamic Fetch Planning, but they now have some support, see http://opensource.atlassian.com/projects/hibernate/browse/HHH-3414. OpenJPA was the first to implement this must have.
EclipseLink has query in memory, which can be used, but the API do not help to leverage it, and EclipseLink’s leadership made it clear that they are not going to make it better, instead they want to push Coherence cache.
Hibernate has an open API for second level cache, which mean you can get out of problem by using another implementation, for example, EHCache seems to be professionally tested, so I would be surprise you find obvious bugs.
I cannot comment on Hibernate source code quality, but I can tell you that locking mechanism in EclipseLink is used to be very fragile, and many concepts are dispersed over the code base.
The runtime monitoring of Hibernate have always been great due to the fact that JBoss have always been strong on JMX, EclipseLink has not much usable features on this.
If I would be you, I would consider OpenJPA or Hibernate instead of EclipseLink, the main reason is that because EclipseLink has a so low user base, I have found lot of obvious bugs in production, like if I was the only user of it. Then, when I submitted bugs to the small development team, which do not encourage user base contribution, they were too busy trying to keep up adding the JPA interfaces on top of their existing proprietary APIs.

Problem setting up WDS with MSI RG54GS2 & Motorola WR850g

Problem setting up WDS with WR850g & MSI RG54GS2
Hi,
I'm trying to bridge 2 routers: Motorola WR850g & MSI RG54GS2 .
I set the MSI as the main router (it works better for me as a router than the Moto), and the Moto is the repeater. I have set it up exactly as the guide on Broadbandreports.com for the Motorola , and on Tom's Networking http://www.tomsnetworking.com/2004/04/14/how_to_wds_bridge/
The Moto sees the MAC of the MSI (Status is UP), the MSI doesn't have a page that shows WDS MACs . I know the routers are connected because when I connect a laptop to the Moto wireless network, it gets an IP (and the DHCP on the Moto is disabled) and the default gateway of the connection is the IP of the main (MSI) router.
The problem is I can't surf anywhere. I can't even ping the MSI router - which should be possible if the WDS works properly.The Moto Wireless Bridge Operation is set properly to Access Point/Wireless Bridge .
Can anyone solve this?
Thanks.

David, welcome to the discussions.
Are you refering to Airport Extreme Setup as the Extreme base.
Or are you using a 3rd party Router as your primary Base, or the Express as the primary base.
Read the supplied link, Not all 3rd party routers are WDS compatible.

Uses for the Action Property with SQL and Oracle DB Adapters

This thread is a complement to the Wiki Article
BizTalk: Streamlining WCF SQL and Oracle Messaging-Only and Other Patterns
The question. In what circumstances is explicitly setting the Action value with the WCF SQL and Oracle DB bindings useful or beneficial.
A complimentary question. Is it even possible to set the Action value to anything other than exactly what is required by the Message.
I ask because of three very specific behaviors of the bindings themselves:
The binding enforces a match between the Action and the Message, therefore...
There is a one-to-one relationship between the Message and Action, but...
The binding is able to correctly derive and perform the requested operation with the unspecific CompositeOperation.
For clarity, I understand how to set the Action. I. understand what the Action represents in the SOAP scheme. I understand how Action can be used as an abstraction for SOAP operations.
Thoughts?

Do you have any good suggestion to learn how to use action property with SQL and Oracle DB adapters? I learn a lot from your replies for years in BizTalk forum. :)

Install SAP ERP 6.0 with Linux and Oracle RAC

Hi Guru,
I want to install SAP ERP 6.0 with Linux and Oracle RAC. Is this possible?
Where do I find information?
Thanks,
Hugo.

Hello Hugo,
You can use either RAC or dataguard. On note [105047|http://service.sap.com/sap/support/notes/105047]:
14. Data Guard
    o You can use "Physical Standby".
    o You cannot use "Logical Standby".
    o You can use Data Guard Broker.
    o You can use Maximum Performance Mode, Maximum Availability Mode and Maximum Protection Mode.
    o In the case of Maximum Availability and Maximum Protection, you must pay particular attention to a fast network connection in order to avoid performance problems.
    o Maximum Protection causes the primary database to terminate if problems occur in the standby database.
60. Real Application Cluster (RAC)
    o You can use this feature in accordance with Note 527843.

Hi Nicloei,
Thanks for the reply. Actually i don't want any work around (Creating MVLOG on table rather than synonym is fine with me) . I just wanted to know it is actually an oracle bug or something else.

Problems setting up WNA with OAS 10.1.2.0.2 and Windows 2008

Hi,
I am trying to set up WNA with an OAS 10.1.2.0.2 in a RHEL 4 platform. I have been able to configure Synchronization and Windows External Authentication following these steps:
http://download.oracle.com/docs/cd/B14099_19/idmanage.1012/b14085/odip_actdir003.htm#i1010999
I have also tried to configure WNA without success with those steps.
The scenario is here:
* OAS 10.1.2.0.2 infra in a RHEL 4
* Windows 2008 SP1 (only i use AD from it)
* Windows XP (client) that should be able to log in without problems when WNA is configured
How can make it work? I haven´t find any useful documentation
Thanks,

Setting isolation level with JDriver for Oracle/XA

edocs (http://e-docs.bea.com/wls/docs70/oracle/trxjdbcx.html#1080746) states that,
if using jDriver for Oracle/XA you can not set the transaction isolation level
for a transaction and that 'Transactions use the transaction isolation level set
on the connection or the default transaction isolation level for the database'.
Does this mean that you shouldn't try to set it programatically (fair enough)
or that you can't set it in the weblogic deployment descriptor either? Also anybody
got any idea what the default is likely to be if you are using an Oracle 9iR2
database? Is this determined by some database setting?

however, for oracle it may not be helpful to change it. Oracle provides two
isolation levels. The default is always READ_COMMITTED. The other
setting is SERIALIZABLE, but this hurts performance, and is also problematic
in the way oracle implements it. For instance, even if you set SERIALIZABLE,
oracle will not lock read data. It will allow other transactions to read and/or
alter data trhat another ongoing SERIALIZABLE transaction has read. The
only way to really lock read data in oracle is to issue oracle-specific SQL in
your select: "SELECT ..... FOR UPDATE".
All in all, you should collect a strong case for why you can't proceed with
READ_COMMITTED first. Then you should research oracle's recommendations
(and their problem record) with SERIALIZABLE.

Problem in Using Log4J with Weblogic 9.2

I am using Weblogic 9.2 and Log4j.
By using Admin console I set the Severity Level to WARNING and inside my java code is given below:
Logger logger = Log4jLoggingHelper.getLog4jServerLogger();
if (logger.isEnabledFor(Priority.DEBUG)){
logger.debug("DEBUG - Test Debug message");
logger.info("DEBUG - Test Info Message");
logger.warn("DEBUG - Test Warning Message");
logger.error("DEBUG - Test Error Message");
logger.fatal("DEBUG - Test Fatal Message");
Somehow the logger.isEnabledFor(Priority.DEBUG) returning 'TRUE' and the follwoing message is displayed.
<Nov 29, 2006 2:44:04 PM EST> <Warning> org.apache.log4j.Category> <000000> <DEBUG - Test Warning Message>
<Nov 29, 2006 2:44:04 PM EST> <Error> <org.apache.log4j.Category> <000000> <DEBUG - Test Error Message>
<Nov 29, 2006 2:44:04 PM EST> <Info> <org.apache.log4j.Category> <000000> <DEBUG - Test Fatal Message>
NOTE - The logger.debug() and logger.info() methods are not invoked because of the severity level to 'WARNING' in the console.
I would like to know why the Somehow the logger.isEnabledFor(Priority.DEBUG) is having a value of 'TRUE'.
I expected only the Somehow the logger.isEnabledFor(Priority.ERROR) will have the value of 'TRUE'.

Did you get an answer to your question? I have the same problem with WebLogic 10.0.

Ok.
Once you get this working, I will have some suggestions that
will make this run much faster. For now, I think the issue
is the driver version. We package an old oracle thin driver
inside our weblogic.jar, so you need to get oracle's latest
appropriate driver, and edit the start-weblogic script so
the driver you want comes before the weblogic.jar in the
-classpath argument for the java line that starts the server.
PS:
I am looking at the code, thank you, but you still haven't
explicitly said what problem you're having!

Hi! I need two more things from you, please:
1 - A full statement of what problem you're having.
2 - More of the code. All I see here is you are getting
a connection directly from Oracle's driver, and code which
does a ResultSet.getString() call.
I need to see the logic from getting the connection, to creating
the statement, to executing the query, to doing ResultSet.next()
for each row and getting the row data for each.
It seems that this is either an application code or jdbc driver
problem because no weblogic code is being used, so it could probably
be duplicated in a small stand-alone program (without any weblogic
stuff).

Differences b/w Oracle Workshop WebLogic and Oracle Eclipse Enterprise Pack

What are the differences between the Oracle Workshop Studio for WebLogic and the Oracle Eclipse Enterprise Pack

While both OEPE and Workshop are Eclipse-based IDEs, they are in fact separate products with some similarities
Both products provide tooling for webapp and Java EE development for Weblogic Server but OEPE is Oracle's strategic Eclipse-based solution and new features are released as OEPE plugins. One goal for OEPE is to cover and eventually exceed Workshop's feature set. You can start to see that today in OEPE 11g's JPA, Spring, and Weblogic Server. For example, JPA support in OEPE 11g is available on more project types, like EJB and Utility Projects, and has better Entity source code completion and validation against the schema. OEPE's Weblogic Server support includes new graphical editors for the common deployment descriptors, like weblogic.xml, which simplifies adding new content, validation, and accessing context sensitive help.
Also, with OEPE we are more active in the Eclipse community with participation in WTP projects like JSF Tools and Dali. In fact, in Eclipse 3.5 the new JPA Entity generation wizards were originally developed as part of OEPE 11g and contributed to WTP.
Finally, if you need support for the latest Eclipse, OEPE's frequent release schedule keeps us supporting new Eclipse versions much faster than we were able to with Workshop.
If you are debating between OEPE and Workshop for new projects, I would definitely recommend that you give OEPE a try.
Thanks,

Example of a successful reverse proxy to APEX using Apache and Oracle HTTP

If this helps anyone, I was able to set up a reverse proxy to APEX with Apache running on the reverse proxy server and Oracle HTTP server and APEX 3.2 on the APEX hosting server. I want to post this due to there is no
documentation on this that I can find. Oracle Metalink could not produce any "How To" document either.
On the reverse proxy server in the httpd.conf file:
ProxyRequests Off
SetEnv force-proxy-request-1.0.1
SetEnv proxy-nokeepalive 1
ProxyPassReverse /pls/apex/ http://apex_server:8080/pls/apex/
ProxyPass /pls/apex/ http://apex_server:8080/pls/apex/
ProxyPassReverse /i/ http://apex_server:8080/i/
ProxyPass /i/ http://apex_server:8080/i/
AddType text/xml .xbl
AddType text/x-component .htc
OR
ProxyRequests off
RewriteEngine On
RewriteRule ^/pls/apex/(.*)$ http://apex_server:8080/pls/apex/$1 [P,NE]
ProxyRequests off
ProxyPassReverse /i/ http://apex_server:8080/i/
RewriteEngine On
RewriteRule ^/i/(.*)$ http://apex_server:8080/i/$1 [P,NE]
And in the Oracle HTTP server httpd.conf file of the APEX hosting server:
NameVirtualHost 999.99.99.9:8080
<VirtualHost 999.99.99.9:8080>
ServerAdmin [email protected]
DocumentRoot "/u01/app/ora11g/product/11.1.0/http_1/ohs/htdocs"
ServerName reverse_proxy_server.com
</VirtualHost>

Here is what I saw :
I have one Web Server 7.0 instance with the following obj.conf :
<Object name="default">
<If $uri =~ "/xyz">
NameTrans fn="map" from="/" name="reverse-proxy-/xyz" to="/"
</If>
<ElseIf $uri =~ "/abc">
NameTrans fn="map" from="/" name="reverse-proxy-/abc" to="/"
</ElseIf>
</Object>
<Object ppath="*">
Service fn="proxy-retrieve" method="*"
</Object>
<Object name="reverse-proxy-/abc">
Route fn="set-origin-server" server="http://server1.sun.com:80"
</Object>
<Object name="reverse-proxy-/xyz">
Route fn="set-origin-server" server="http://server2.sun.com:80"
</Object> ...When I send a request to URI :
/abc/test1.html : the request gets served from server1 from docs/abc/test1.html.
/xyz/test2.html : the request gets served from server2 from docs/xyz/test2.html
Where as when you change obj.conf to (note the change in "from" parameter in "map" SAF)
<Object name="default">
<If $uri =~ "/xyz">
NameTrans fn="map" from="/xyz" name="reverse-proxy-/xyz" to="/"
</If>
<ElseIf $uri =~ "/abc">
NameTrans fn="map" from="/abc" name="reverse-proxy-/abc" to="/"
</ElseIf>
</Object>
<Object ppath="*">
Service fn="proxy-retrieve" method="*"
</Object>
<Object name="reverse-proxy-/abc">
Route fn="set-origin-server" server="http://server1:80"
</Object>
<Object name="reverse-proxy-/xyz">
Route fn="set-origin-server" server="http://server2:80"
</Object> ...In this case when I send a request to URI :
/abc/test1.html : the request gets served from server1 from docs/test1.html.
/xyz/test2.html : the request gets served from server2 from docs/test2.html.
