Embedded OC4J Server - Turn off BC4J debugging

Hi all,
I am just switching over from Eclipse(Rational RAD) to JDeveloper and using BC4J. I am struggling a bit with the embedded server under 10.1.2. The console messages roll off the top. Argh.. I want to shut down as much unnecessary logging as possible. BC4J put MANY messages out there. I see a reference to adding -Djbo.debugoutput to the start command in order to turn off the debugging messages. I cannot find where the embedded server is started. It is NOT started from C:\jdev1012\jdev\bin\start-oc4j.bat. Can anyone help with this?
Thanks,
--Amy Smith

Only reason for 10.1.2 is that I just joined the company 6 weeks ago and they had not upgraded to 10.1.3. I very much want to do that but was left with some work that was overdue and can't take the time right now as I understand there are some differences that may make migration difficult...
Sigh ... I am missing IDE functionality from Eclipse that is in 10.1.3.
...Thanks for the help

BUG: JDev 10.1.3.0.4 Embedded OC4J Server Preferences

If we specify in the Embedded OC4J Server Preferences->startup a OC4J installation to use for running and debbuging, click ok, and then delete the choosen directory and try again to access the Embedded OC4J Server Preferences, an error occurs. Appears an dialog and we can not alter this anymore.

Hi,
not sure on the limitation of dbms_output.put, but 4000 characters happens to be the maximum size of a varchar2 column....
I normally use dbms_output.put_line for debugging PL/SQL.
You could also post in the database forum if you have no luck here.

The 10.1.3 version of JDeveloper (and the embedded OC4J) requires JDK 5.0 to run.
You can however set your project to work with JDK 1.4 in the project properties.

JDBC datasoure that works for embedded OC4J server of JDeveloper 10.1.3.4

Hi all,
I have this in the Application Module as JDBC datasource: java:comp/env/jdbc/DBCON
That works fine if I deploy the application on Oracle application- or tomcat-server.
On the connections tab in JDeveloper I have made a database connection with the name DBCON.
But when I run the application from Jdeveloper with the embedded OC4J server I get this error:
Unable to lookup Data Source at context java:comp/env/jdbc/DBCON
What do I do wrong?
Thanks in advance.

Hi,
Edit the <application_name>-data-sources.xml file under the root directory of your application, and setup a managed data source and connection pool with the data source having the correct jndi name, eg. jdbc/DBCON
You can either do this manually (which I find easier), or use the tool within JDev
Tools - > Embedded OC4J Preferences -> Current Workspace -> Data Sources -> New

SQL not showing in Embedded OC4J Server window

Previously, when we'd run a page through JDeveloper, the sql statements that were used to execute the query would appear in the Embedded OC4J Server window in JDeveloper. Now they no longer appear (along with a lot of other logging data that used to appear). Is there a configuration setting somewhere to make this info appear again?

There is no such setting for OC4J log. Are you sure that you are looking at the right tab because there are generally 3 tabs on the bottom most log window which are Messages, Compiler and Embedded OC4J Server.

Embeded OC4J server within JDeveloper does not pick latest JAR files.

Hi,
Currently OC4J seems to be using an older version of JAXB1.0. Hence I created a shared library in my standalone OC4J server and imported the shared library while deploying my applicatoin in the ClassLoader task.I am trying to replicate the same in
my embeded OC4J server within JDeveloper.
I followed as indicated in readme.txt file in the \j2ee\home\shared-lib\ folder.
1) I created a folder called "jaxb" within /j2ee/home/shared-lib/. I then created a folder with the name "2.0" indicating the version number of the API.
2) I then added the relevant jaxb JARS to the jaxb/2.0 folder.
3) In the server.xml file available under /j2ee/home/config/ , I added the following entries.
<shared-library name="jaxb" version="2.0">
          <code-source path="jaxb-api.jar"/>
          <code-source path="activation.jar"/>
          <code-source path="jaxb1-impl.jar"/>
          <code-source path="jaxb-impl.jar"/>
          <code-source path="jsr173_1.0_api.jar"/>
          <code-source path="jaxb-xjc.jar"/>
     </shared-library>
I am still facing the issue where my embedded OC4J server is picking up the jaxb version 1.0.
What are the steps that needs to be taken to ensure that the embeded OC4J
takes in the jaxb2.0 version.

If you have Web project, check if HTML Root Directory has got a Null value ?
Double-click on the project to bring up project properties
Select Input Paths
See the value for HTML Root Directory.
If it is Null or invalid, edit to make sure it is valid and Click ok.
If not, create a new/empty project and see if you can launch Embedded OC4J server preferences dialog for that project.

as a result I am getting unexpected behavior from the Application

try{
PreparedStatement pstmt = conn.prepareStatement(sql1);
pstmt.setString(1, studid);
ResultSet rs;
rs = pstmt.executeQuery();
//mypidm = rs.getInt("SPRIDEN_PIDM");
This part of the code drops through i.e. rs.next() always gets a false result
while (rs.next()) //evaluates to false so mypidm is always zero.
mypidm = rs.getInt("SPRIDEN_PIDM");
I am thinking that these two things are related.
Any Thoughts.

The tables are not created by default. You can configure your persistence.xml to define how you want tables to be created. The persistence.xml properties are defined in the TopLink class, EntityManagerFactoryProvider (oracle.toplink.<essentials>.ejb.cmp3).
Set the property, "toplink.ddl-generation" to "drop-and-create-tables" if you want them recreated every time your redeploy. Note this will delete all previous data in the tables, so make sure you do not leave this setting on when you go into production.

How to use the HTTP Analyzer with the embedded OC4J server?

JDeveloper version: Studio Edition Version: 10.1.3.0.3.3412
I have a web application, which I run in the embedded OC4J server.
I tried to use the HTTP analyzer to inspect http requests and responses, but I could not make the analyzer work.
I tried to setup the HTTP analyzer by looking at the help entry, but I could not make it work.
If the HTTP analyzer works for you in the embedded OC4J server, please write the steps on how to setup the analyzer.
(Maybe I could not make the correct settings about port numbers?)
Thanks in advance,
Regards,
Turgay Zengin

I was able to use the HTTP Analyzer by changing the proxy setting directly in Internet Options. Check the browser/proxy settings set in JDeveloper preferences and copy them to the Connections tab of Internet Options. See if that works for you.

How to set up data source for JDeveloper's embedded OC4J Server?

Help needed. I Created a BMP EJB and tried to test
it with JDeveloper's( version 9.0.3) embedded
OC4J server. For JDBC, I created a data source
in data-source.xml lacated in JdeveloperHome\j2ee\home\config. However,
when I run the test client. I got the error
from JNDI lookup:
java.rmi.RemoteException: jdbc/entdatasource not found
Could anybody with similar experience help?
Thank you in advance.
-John Wang

Try making your changes in the data-source.xml located @ JDev_root\jdev\system9.0.3.1035\oc4j-config.
You can tell that this is the one to be modified by watching the log when you start the OC4J server. Look for the line that says C:\JDEV\JDK\bin\javaw.exe -ojvm -classpath . . .
the -config option will point to where the server.xml is used from, the same dir should be where you get your data-source.xml

Hi,
Can any one guide me and help in configuring a custom jaas loginmodule in embedded oc4j? Thanks in advance.
I need to use Oracle DB user & roles for authentication and authorization for my j2ee application. I followed all the steps given in Franks document in URL http://www.oracle.com/technology/products/jdev/howtos/10g/jaassec/index.htm
I just changed DBProcLoginModule defined in the article's example to DBSystemLoginModule. Ofcourse, I used specific jazn command defined for DBSystemLoginModule to generate entires in jazn-data.xml. But it had no effect when I ran the application and login with db user name password. Authentication fails and my debug log shows that the custom login module is not getting invoked at all. I have FORM based authentication with the roles & constraints defined properly in web.xml and orion-web.xml where default oc4j authentication with admin/welcome works perfect. (I also have an entry for a role defined in oracle db in the web.xml & orion-web.xml files)
Also, I referred URL http://technology.amis.nl/blog/?p=1462 and added <property name="custom.loginmodule.provider" value="true"/> to <jazn provider="XML" in application.xml. When I tried running the application and deploy the module I am getting the following exception and deployment fails.
* I am using JDeveloper with embedded oc4j 10.1.2.
* I havent used password redirection mentioned in Frank's document for now.
Error: Unexpected error during lookup : Lookup error: javax.naming.AuthenticationException: Invalid username/password for default (admin); nested exception is:

Help, I can't get the Embedded OC4J Server to restart!

I've run into the following problem (well, actually a collegue) in that I can not get the OC4J application to restart once I kill it. She has a JSP page which will run once upon the first time JDeveloper 9i is run. However, from that point on, changes are compiled, but the I.E. page never comes up. I traced the problem down to the OC4J internal server is not being restarted. It seems the underlying reason is that somehow the embedded server gets in a state where it can't be shutdown.
I've tried directly killing it via the run manager tab, and I've even looked at task manager and in both cases, I don't see anything corresponding to the server. Even restarting JDeveloper proper doesn't seem to clear it.
Any thoughts?
Thanks.

I assume you are asking about JDev 9.0.2. If it's another version, please let me know. I can offer some suggestions based on the most likely causes:
1) Try disabling the proxy server in JDev. Go to Tools | Preferences - Proxy Server, and uncheck the "Use HTTP Proxy Server" checkbox. You will have to quit and relaunch JDev for the change to get picked up. Then try running your JSP again.
2) Try telling JDev to use a specific hostname for your machine other than the default. Go to Tools | Preferences - Deployment, and click on the radio button that says "Specify host name:" Try putting localhost or 127.0.0.1 here. You may have to use this in combination with 1).
The embedded OC4J proces will show up in the Windows task manager as a javaw.exe process. You shouldn't have any zombie OC4J processes, but if you do end up with them and have a reproducible case, please post the steps-to-reproduce here.
