BC4J, JSP, Deployment problems

I have two simple projects, one containing business components, and the other containing a JSP and a data web bean, which use the application module in the first one. I have deployed successfully the business components project as an EJB to Oracle8i and I am able to connect to it from a simple client code, as well as from the JSP application in JDeveloper 3.2.
However, when I deploy the JSP application to 9iAS, I get the following exception:
Exception:
java.lang.RuntimeException: java.lang.NullPointerException:

I have the properties file in place in a jar and have set the classpath to all the necessary libraries.

You could try something like this in your jsp

HELP: JSP deployment problems

Hi,
We have been working hard to resolve our deployment problems, but we are stuck at the following point.
We create the following directory tree.
htdocs/debis/
htdocs/debis/WEB-INF/
htdocs/debis/welcome.jsp
htdocs/debis/mail/
htdocs/denis/mail/readmail.jsp
welcome.jsp works fine.
now the problem is readmail.jsp cannot access the beans in the WEB-INF. mail tries to become a new application root. So we added another WEB-INF under mail, but then it turned out that different application roots are unable to share sessions. What we want to achieve is to have one application root, with several sub applications which are sharing sessions.
Currently we put all jsp files in the
htdocs/debis
directory to make it work. However the directory is now full of jsp files, which we are having hard time determining which belongs to which sub application.
What should we do?

Hi, I am a newbie in running JSP in Apache with Oracle 9iAS. I have only worked with JSPs in Tomcat. Please bear with me.
Before I can run the JSPs in the htdocs/myJSPapp/, beans & servlets in htdocs/myJSPapp/WEB-INF/ folder, what do I need to have installed ?
Is it OSE + mod_ose + Apache + 9iAS ?
Or is there a better alternative for serving out JSPs ?
Thanks!

BC4J:jsp:deployment

I implemented a Jsp application based on BC4J and I want to deploy it to the server.
as shown in the Jdeveloper Help; first I have to deploy the BC4J as Oracle8i EJB Session Bean. but the problem is that I don't know how to establish an IIOP connection. My question is can I deploy the BC4J project as an Oracle application server; and so I have not to specify aN IIOP connection.
any help is appreciated.

You have to pre-config the standalone oc4j with BC4J installer to setup the bc4j runtime on the oc4j.

NEWBIE JSP Deployment Problems

I know this is will probly bore to some of you but I'm trying to evalutate this software.
I created a test JSP via the wizard and ran it in Jdev ok. Deployed and Copied the files to the Apache web server provided with 8.1.7. Ran on browser and got this error:
java.lang.RuntimeException: JSP Registry could not locate runtime property file:....
I included the business classes but apparently I'm still missing something...
I have been searching for documentation on this error but not much luck so far...

I have deployed a JSP with BC4J Application on an Oracle IAS and it works fine, but to do it i had to include a path to the .jar file that contains my classes in Jserv.properties
When i need to change, add or manipulate something in the jar file or include a new jar file, i have to shut down the service because while active, the files that are being pointed by the conf file become locked... I have read something about "zones" and i have no idea about apache or OracleJSP configuration. I began yesterday to read the JavaServer Pages Developer4s Guide and Reference... But it has 420 pages and i will last a lot till i find what i4m looking for.
If you can explain me the way you make your jar file accesible by the system in a correct way or the pages in which it is explained, please, make me know.

JSP Deployment problem

I kow this topic has been posted but there seems to be no resolution to it. I am having the same problem.

Ejb and jsproc deployment problems

Am trying to deploy the java stored procedure (jsp) example
(jsproc subdirectory in acmevideo directory) and the enterprise
java bean (ejb) example (ejb subdirectory in acmevideo
directory). Both use the business and util subdirectries of
acmevideo directory. These examples are provided with
JDeveloper.
In the case of the jsp example, the files compile fine in
JDeveloper. The deployment profile file is created okay using
the Stored Procedure Profile Wizard. But when the jsp is
attempted to be deployed by right clicking the deployment
profile file menu in JDeveloper, the following errors appear:
SQL error during creation of acmevideo/util/DataWrapper
ORA-00922 - missing or invalid option
SQL error during creation of acmevideo/business/TitleQueries
ORA-00922 - missing or invalid option
Is there a corrective action for these errors? Are the details
recorded in any log so that these errors can be troubleshooted?
In the case of the jbe example, the files compile fine in
JDeveloper. The deployment profile file is created okay using
the EJB Profile Wizard. But when the jsp is attempted to be
deployed by right clicking the deployment profile file menu in
JDeveloper, the following happens:
The message indicating that the deployment will take a few
minues continues to show forever. There is no completion,
and one is forced to cancel the process.
This happens when using the port settings of 1521, 1526 (Oracle
listener ports) or 2651 (OAS ORB port). Specifying the service
or omitting it yeilds the same results.
Is there a corrective action for this? Are the details recorded
in any log so that these errors can be troubleshooted?
For both the situations, is the classpath variable need to set
outside the JDeveloper environment?
Also am not able to locate the Oracle 8i CORBA and Enterprise
Java Beans Developer's Guide and the Oracle 8i Java Stored
Procedure Developer's Guide referenced in Building Java
Applications for Oracle 8i anywhere.
Would appreciate any help in this area.

: Has anyone been able to deploy an ejb from JDeveloper2 (Beta)?
We have ;) But I guess that doesn't count... Please have a look
at the online demo for Enterprise JavaBeans on this technet
website. You can get there through the JDeveloper Tech Info page.
Please open a new thread if that doesn't help you.
Thanks,

JSP Deployment Issues

Guys:
 I saw your names posted in the weblogic jsp news group. I thought you
 might be able to help me with a jsp deployment problem. A number of our
 jsps take a long time to compile. As a result, the first user who
 accesses our jsps after deployment pays a significant latency penalty.
 To get around this problem, we manually "touch" each jsp as part of
 deployment. That way when users access the site, they get reasonalble
 response time.
 The problem we face is that we are now in a clustered environment in
 production and staging. As a result, it can take a long time to
 manually "touch" each jsp. There is also a secondary issue. Our
 staging and production environments are hosted by an extenal service
 provider. We are uncomfortable with deploying source code -- e.g., jsps
 -- in these environments.
 Here is what I have done to date:
 I have written a unix script that invokes the weblogic.jspc compiler for
 each jsp. The intent is to pre-compile the JSPs ahead of time. In our
 testing this script we still notice that Weblogic (e.g., 4.5.1) still
 attempts to recompile the jsps on-demand when they are first accessed
 from the browser by the first user after jsp deployment. (This defeats
 the purpose of pre-compiling the jsps.)
 What are we doing wrong and what can we do so that the jsp-s are
 pre-compiled and not re-compiled on demand. Again, at a minimum we want
 to avoid the latency problems associated with the first user. Best case
 scenario, we would like to ship a jar file that contains the compiled
 jsp servlet classes.
 Your recommendations are most appreciated.

I've never tried this, but I don't see any reason why it wouldn't
 work... Don't even register the JSPServlet. Build the JSPs (servlets)
 and deploy them like any other servlet. You can register them with a
 .jsp extension or you could give them a different alias altogether.
 The WL JSP compiler (weblogic.jspc) may be used to compile the jsps
 into servlets during the normal build process and there are options
 that may be used to modify the package, install dir, etc.
 Hope that helps.

Bc4j jsp calendar deployment problem

Using jdeveloper 9.02 I made a simple webapplication with bc4j jsp's and deployed it to oc4j (9.0.2.1) directly from jdeveloper as described in the help. This works fine, except for the calendar (datepicker). When the calendar is loading in a separate frame I become an 'access is denied' error. In the http-web-access.log the following line shows up:
127.0.0.1 - - [25/Nov/2002:15:52:54 +0100] "GET /webapp/jsp/calendar.jsp?redirect=/webapp/jsp/calendar.jsp&locale=de_AT&enc=windows-1252&origValue=1980-12-24&format=yyyy-MM-dd&formatter= HTTP/1.1" 500 383
The application runs fine on the oc4j inside jdeveloper, so I assume it is a configuration problem. However, so far I couldn't find out what is wrong.
If I make a simple application using the wizards for the emp table, and deploy it with standard settings to the local oc4j, I have exactly the same problem.
does anybody have a suggestion?
thanks, Cor

problem is solved.
Webapp and cabo are installed as applications in their own directory structures. However, the required libraries are not deployed automatically in the web-inf/lib directory. They are present in the main application web-inf/lib, but these are apparently not accessable. Copying the libraries solves the problem.
I'm still wondering whether I did something wrong. Simply deploying the bc4j.ear to oc4j is obviously not enough, but that is what the jdeveloper help is saying. Did I misunderstand something?

I had very similar problems with adding the correct JDeveloper .jar files to Tomcat's lib folder, but did eventually resolve my issues.
The problem I am having now, however, is the following error message:
Error Message: oracle.jbo.html.RequestParameters.addParameter(Ljava/lang/String;Ljava/lang/String;)V
Yes, I have deployed the bc4jhtml.jar file from JDeveloper to Tomcat\common\lib!
My web-app is a very simple BC4J JSP application. I have one BC4J component in its own project and JAR file, and one JSP referencing that BC4J component - I deploy the BC4J JAR along with the WAR file from the JSP project. Needless to say, the JSP works fine within JDeveloper..!
I'm using JDev 9.0.3 and Tomcat 4.1.12. Does anyone have any suggestions?
Thanks,
S.

BC4J, JSP, Apache: Deployment to web-inf

I'm trying to deploy a BC4J JSP application to a web-inf directory. In other words I'm using the OracleJSP extensions that support the globals.jsa application/session context.
When I place my application's BC4J jar file in the \approot\web-inf\lib directory it doesn't work. When I try a simple app with no BC4J its works. ie. My JSP works and it can load classes from both \approot\web-inf\classes and \approot\web-inf\lib\??.jar.
If I place the application BC4J jar file in \approot\web-inf\lib it can't find files such as \bc4jpackage\common\bc4j.xcfg. Therefore I think OracleJSP will load classes from \web-inf but because its not really in the JServ classpath BC4J wont find any other files.
Anyone tried this? Is there a workaround?

Hi,
I am yet another victim of the age-old error JBO:33001 bc4j.xcfg file not found in class path, When i have my BC4JApp.jar in Tomcat Web-inf/lib directory. All the other jar files and class files in my webserver-application web-inf classes and lib directory works.
But Tomcat server is not able to read this bc4j.xcfg file. I can see in my jar file that this bc4j.xcfg exists and in the specified package directory. still the problem persists. My BC4JApp.jar is perfectly working when i use JDeveloper. but not when i use tomcat4.0 and call a JSP using BC4JApp.jar from browser (My environment is Jdeveloper3.2, Tomcat4.0+IIS in middle tier and oracle 8i as DB, everything on windows2k)
I have gone through almost all the threads possible that relates to this error in this form. None of them have a answer except to say "put the file in classpath". and last reply is "will fix in jDeveloper 9i. So what happens to us who are working in Jdeveloper 3.2?
1. I have this file in my jar file.
2. I also tried creating a seperate directory manually, with the same name as my package under web-inf/classes, web-inf/lib , just under web-inf directory and atlast under approot directory also. I tried having my package directory containing bc4j.xcfg in these folders one at a time and also tried having this directory in all these folders at the same time.
Still no solution.
Itz frustrating that neither proper documentation nor a right url page nor i am aware of available addressing this. page links given in above threads only gives me the wonderful page of ie's "Page cannot be displayed".
Is there a answer to this error and my problem. If this doesn't work, then i have to all the way develop from scratch creating my jsp using JDBC calls and Stored packages etc.
I don't want to give up on this Jdeveloper at this final moment because if this bc4j.xcfg file is found, my application will work perfectly. on these final moments, if this doesn't work, i am frightened to imagine to develop my application in standard way. Atlast, if thatz the option left,we have to do that bcos our production date is close by.
Please can some one in this forum or Jdeveloper help me to solve this problem. I am desperate and very urgent.
Waiting for a reply from Jdev team very much...
Thanks

Error Deploying a BC4J JSP Application on IAS

When I am trying to run a BC4J JSP Application on IAS I have the following message:
Error Message: JBO-30003: The application pool, BC4JDemojsp_BC4JDemo_BC4JDemoModule, failed to checkout an application module instance.
Error Message: JBO-25002: Definition BC4JDemo.BC4JDemoModule of type ApplicationModule not found

Gina,
I would recommend checking out the following HowTo's recently posted on OTN by the JDev Team. They may indicate where your problem is occuring and how to fix it:
Set up your Webserver to run BC4J: http://technet.oracle.com:89/ubb/Forum2/HTML/006397.html
Deploy a BC4J JSP Application on iAS and Tomcat: http://technet.oracle.com:89/ubb/Forum2/HTML/006398.html
How to Deploy Multiple BC4J JSP Web Apps to the same Webserver: http://technet.oracle.com:89/ubb/Forum2/HTML/006726.html
Note, if you are deploying on iAS, the Online Orders tutorial application comes with that release, so you might want to refer to the last HowTo to make sure your webserver is set up to handle multiple apps, even if one if them isn't yours!

Deploy BC4J/JSP-Struts to IAS

HI,
I'm trying to deploy a BC4J/JSP-Struts application to IAS. This application was developed with JDeveloper 9.0.3.
I can deploy this application to a Standalone OC4J (delivered with JDeveloper 9.0.3) on Windows2000 without problem.
Then I want to deploy this application on Oracle9iAS 9.0.2. For this I create an .EAR file with JDeveloper and I start the OC4J Administrator tools from Oracle9iAS and deploy my application.
I start the application with
http://erbium.int.imd.ch:7778/InvoicesInterface/main.jsp?user=x-XxX
and I become the menu without Problem.
Then I click on the link
http://erbium.int.imd.ch:7778/InvoicesInterface/VInvoiceUsersView1_Browse.do?user=x-XxX
and I become following :
HTTP 500 Internal server error
The page cannot be displayed
Did you have any Ideas ?
Thanks Yves
Configuration:
- Oracle9iAS (9.0.2) on Solaris
- JDeveloper9.0.3

I am not able to pinpoint the exact error you are having but here are some obervations
a) You are going backwards in versions of OC4J when you deploy to 9iAS 902. If you are using JDev 903, then it is running with a local version of OC4J 903. When you are deploying to 9iAS 902, it's a earlier release of OC4J, so there may be an issue there. There is a 9iAS 903 version available from OTN that would be better to use in this case.
b) Is the struts framework packaged as part of the EAR file you are deploying? i'm not familiar with how BC4J and Struts apps are packaged from JDeveloper, but this is something to check on for sure. The local OC4J running inside of JDeveloper may have the Struts libs configured at the server level.
c) You might want to try and change the show-friendly-error-messages (or something like that) property inside of IE (if you are using it) so that it will display the stack trace the server might be sending. this may be of help to further locate the source of the problem (ClassNotFoundException, etc.).
