Deploy BC4J to 8i

Hi!!
Hope to get help here.I developed BC4J appln in Jdeveloper3.1 and wld like to deploy it as Oracle 8i EJB session Bean .When I tried Deployment an error occured as follows-
'Generating EJBHome and EJBObject on the server...
An exception occurred during code generation: Class not found: restaurant.common.ejb.RestaurantModuleHome.class
*** Errors occurred while deploying the EJB to JServer ***
*** Deployment completed ***'
- Now shd I try the complete deployment again (will it overwrite previous stuff?) or is there some other way?
Thanx,
Swati

And another thing, is there any way to have the ADF Runtime Installer install the ADF Runtime into another JBoss config directory. As far as I noticed, it will only install into the JBoss default config directory.
TQ in advance.

Hi Cleber,
Is it possible that you can send me a copy of your original 10.1.2 project which contains these diagrams so that I can take a look? The diagrams should open fine in 10.1.3.0.4.
My email address is [email protected], if you could zip up your project and then change the .zip file extension to .zap to get it through the email server.

Prolbem deploying BC4J in Oracle 8i for NT

Hello,
We're testing the sample of BC4J distributed with JDev 3.0.
When we test it localy, it works ok. Our problem arises when we
try to deploy the BC4J as a EJB on Oracle 8i on NT. First when we
deploy the BC4J runtime the deployment process returns some erros
like the following one:
Error while resolving class
oracle/jbo/server/DatabaseTransactionFactory
ORA-29554: unhandled Java out of memory condition
resolving: oracle/jbo/common/remote/PiggybackReturn
resolving: oracle/jbo/server/xml/JTPersistable
resolving: oracle/jbo/server/util/JboSQLUtil
Error while resolving class oracle/jbo/server/util/JboSQLUtil
ORA-29554: unhandled Java out of memory condition
(Oracle 8i has 100Mb of Java Pool Size and we tryed
increasing this aspect but without results)
After the BC4J runtime finished, the BC4J deploy stars
returning the next error:
Reading Deployment Descriptor...done
Verifying Deployment Descriptor...done

An exception occurred during code generation: null
*** Errors occurred while deploying the EJB to JServer ***
*** Deployment completed ***
Does anyone know which is the problem?
Thanks in advance.
null

OK. I know it's bad form to reply to your own messages...
I've found and executed the SQL script but the SELECT statement returns no rows.
I'm still getting ORA-29554 for a number of classes. A java_pool_size of 120Mb has made no difference. Can anyone suggest any other settings that might be causing the problem.
Maybe somebody who has successfully deployed BC4J to 8i could post/email me a spool of "show parameters" from server manager....?
Thanks,
Rob.

Strange exception when deploying BC4J as EJB in 8i CORBA.BAD_PARAM: null Strings are

I am trying to deploy BC4J as Ejb to 8i (8.1.6). I use the following deployment method with j: my Jdev root.
setjboenv j: ejb8i
loadjava - u user/passwd@host:port:sid - thin -v - r grant "SYS,PUBLIC" j:lib\xmlparserv2.jar
loadjava - u user/passwd@host:port:sid - thin -v - r grant "SYS,PUBLIC" j:lib\jbomt.zip
loadjava - u user/passwd@host:port:sid - thin -v - r grant "SYS,PUBLIC" j:lib\jboejb.jarI then create a deployment profile for ejb 8i with the ide. (Without deploying)
I then use loadjava outside the IDE to deploy the 2 jar files created
MyProject1CommonEJB.jar
and
Myproject1.jar
I then use the ide again to deploy the bean profile
Package1ModuleServerEJB.prf
The last step fails with the error :
Publishing EJBHome...org.omg.CORBA.BAD_PARAM: null Strings are illegal in IIOP. Please correct your application or run the ORB in backward compatibility mode. minor code: 0 completed: No
void oracle.aurora.ejb.deployment.GenerateEjb.invoke()
void oracle.aurora.server.tools.sess_iiop.ToolImpl.invoke(java.lang.String[], java.io.InputStream, java.io.PrintStream, java.io.PrintStream)
void oracle.aurora.ejb.deployment.GenerateEjb.main(java.lang.String[])
Exception in thread main
Strangely, when I test this EJB with the tester (middle tier = remote ejb) it works, but from JSP's I get an application error : "Unknown Exception"
I am using Jdev 3.1
Also using the deploy option when creating the deployment profile fails apparantly due to the missing grant "SYS,PUBLIC" when loading classes to the database before deploying the bean.
What can be done ?
null

Hi Blaise
Thanks for the reply. I have tried to do the complete deployment from within Jdev, but now I get the following error right at the end of the deployment.
/BC4J1AppModuleEjb/EjbObject_RemoteBC4J1AppModuleEjb:ORA-29535: source requires recompilationjava.lang.NullPointerException at sun.tools.java.Environment.error(Environment.java) at sun.tools.java.Environment.error(Environment.java) at sun.tools.java.Environment.error(Environment.java) ..... etc.
I have tried to deploy to a clean schema with the java privilages granted as described in the Jdev release notes.
I included the following libraries in my project :
JBO JDBC816 PATCH
JBO OSQL Domains
JDeveloper Runtime
Oracle 8.1.6 JDBC
Connection Manager
JBO Runtime
JBO VB Runtime
JBO 8i Runtime
SQLJ Runtime
JBO 8i Client
JBO Vanilla Domains
JBO EJB Runtime
JServer
Oracle XML SQL Utility
ORACLE XML Parser 2.0
Then I just used the deployment wizzard

Urgent!!! problems deploying BC4J to Oracle 8i

I have the following problem deploying BC4J to Oracle 8i as EJB :
When I tried to deploy as an EJB following the guidelines in the following help page:
Contents help--> Developing Business Components-->Deploying Business Components-->Creating Deployment Profiles and Deploying
I get the following error :
An exception occurred during code generation: Class not found: bc4jEjbtrial.common.ejb.DeptAppModHome.class

Could someone please tell me where I am possibly going wrong?

What version of jdev are you running? The Bc4jtrial package sounds suspicious.
Thanks

Problem with deploying bc4j into Oracle 8i

Hi ,
We are trying to deploy bc4j in to Oracle 8i. Using the
business componets tutorial as a guideline, we have created
business components for a master detail relationship between dept and emp tables. When tested using the business components tester in
JDev 3.0 in the local mode it is working well. Then we made
the application remotable to be deployed as a corba object in
Oracle 8i database. When the deployment is done the following errors
are occuring during resolving.
resolving: oracle/jbo/server/DatabaseTransactionFactory
Error while resolving class oracle/jbo/server/DatabaseTransactionFactory

ORA-29554: unhandled Java out of memory condition
But at the end we are able to resolve all classes from the sqlplus using alter java class .... resolve.
After resolving all the invalid classes manually, when we try to test
the application using business component tester in Oracle 8i mode
we end up with the error
String index out of range: -25
The same thing happens when we are trying to deploy the business components as an ejb in Oracle 8i as well.
Oracle 8i (8.1.5) is running on Windows NT. Java pool size is 60MB
Ramanujam S

You need to configure the Java shared pool size in the init.ora for the RDBMS. The default is 20 MB and this is not enough for deploying the BC4J into the RDBMS, try 50 MB (or more if you can afford it). There are a lot of classes in the BC4J and the resolver needs a lot of temporary space to take care of loading and resolving these.

Although this explains how to then deploy to Weblogic on another server, it still presumes that it is installed on the same computer as JDev. I moved the weblogic.jar file over to the computer and fudged a few things to get it to work.
Also, I am testing this with Weblogic 6.0, so some of the information does not work as prescribed. I edited the config.xml instead of the weblogic.properties file. I am trying to figure out where to put all of the *.jar and *.zip files that I copied over to the Solaris machine with Weblogic. Any suggestions?
And one of the steps in the section to create the deploybc4j.cmd file is wrong. It says
"%JAVA% weblogic.ejbc -compiler javac f:\jdev32\myclasses\wlappmodule.jar f:\jdev32\myclasses\wlAppModuleGenerated.jar;f:\jdev32\lib\jbodomorcl.zip"
Which does not work. I took off the last part:
"%JAVA% weblogic.ejbc -compiler javac f:\jdev32\myclasses\wlappmodule.jar f:\jdev32\myclasses\wlAppModuleGenerated.jar"
and it worked. It was getting that whole last part and trying to create a directory with that name and failing.
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by David Shanes ([email protected]):
This seems to assume that JDev and Weblogic are installed on the same server (I refer to the section on setting the setenv.cmd file in the WEBLOGIC_HOME dir that includes the path to the JDev install.

JBOSS WONT DEPLOY BC4J.EAR - FAILS

Following instructions found elsewhere in OTN, I have set up JBOSS to use BC4J by copying relevant files to the JBOSSHOME/lib/ext folder and by deploying BC4J.EAR into the JBOSS deploy folder. Deployment fails mentioning that it is missing a class ...emd.EMDServlet. This class appears in emd.jar and BC4JHTML.jar alike, probably the latter is relevant (not sure). Has anyone else had trouble deploying BC4J.EAR? Using BC4J.EAR from JDeveloper 9.0.3.

Would you please post more error message?

Deploy BC4J in JDeveloper 3.1.1.2 to Tomcat

Need help on how to deploy BC4J in JDeveloper 3.1 to Tomcat web server
Thank you very much,
jen

JDeveloper's convention is to put:
- .java files in <jdev>\myprojects
- .class files in <jdev>\myclasses
- .html and .jsp files in <jdev>\myhtml
But none of these are mandatory. I suggest you start by creating an empty project and adding all of your files to the project.

Unable to deploy bc4j component properly

I m deploying bc4j from the machine on which oc4j rel 2 server
is running using
jdev 9i, i m facing the following prob.
My applicatin is made in jsp & bc4j.
1. It is giving some EOFException at the time of deploying.
After deployment
some jsome links are working and some are not working.
2. Can we deploy from other remote machine on the oc4j server????
3. how do we use a component already deployed on the server in
our other oc4j
programs??
3. In our system there is a lot of repeatitions of same entities
in different
- application module so how do we redue that?
i wd apreciate any answer this query.
regards

hi,
can you please provide more details on this issue.
Which links are working and which links are not working?
What do you mean by the question: can we use other component in the server in our oc4j. What components do you mean?
I hope an answer to these questions will clarify the issue?
thank you

Issues with deploying BC4J/JSP applications on OC4J

To everyone who's been having problems deploying BC4J/JSP applications to OC4J.
We are aware that you're having problems deploying to OC4J, and we're working on them. OC4J was not available in time for us to add support for OC4J deployment to the JDeveloper 3.2.3 release. In addition there are some bugs in the first release of OC4J that have an impact on BC4J applications. This note describes the issues, and how we plan to address them.
Issue 1: Classpath problems
People have been getting "class not found" or "properties file not found" errors when they try to run their JSP. The answer is to make sure that all relevant archives and your JSP's .properties file are in the OC4J classpath - there's a note addressing the .properties file problem at http://technet.oracle.com:89/ubb/Forum99/HTML/000028.html. In general though, setting up the classpath can be tricky.
Issue 2: JSP TAG NOT RELEASED ON END TAG. SAME TAG IS REUSED.
This issue affects JSP pages whose behaviour relies on a tag instance being cleaned up as a result of release() being called.
Your tag will not be released, and subsequent instances of the tag will reuse the first instance, rather than instantiating a new
one.
Issue 3:JSP SCRIPTABLE VARIABLE NULL
A scriptable variable set in a tag cannot be accessed by a scriptlet. For example, this JSP code will throw a
NullPointerException, because the scriptlet cannot access the value of resultRow:
<jbo:Row id="resultRow" action="CURRENT" datasource="customer_vo1" />
<%
session.putValue("FIRSTNAME", resultRow.getAttribute("Firstname").toString());
%>Workaround: Add a line of code at the beginning of the scriptlet to explicitly get the variable's value from the page context, for
example:
<jbo:Row id="resultRow" action="CURRENT" datasource="customer_vo1" />
<%
resultRow = (oracle.jbo.Row)pageContext.findAttribute("resultRow");
session.putValue("FIRSTNAME", resultRow.getAttribute("Firstname").toString());
%>
What we plan to do
To address issue 1, we're currently testing a utility that installs the BC4J runtime libraries to OC4J, and provides a script to start OC4J with the correct classpath. We plan to post this by the end of this week, along with instructions for deploying a BC4J application to OC4J; deployment will be a lot simpler after running the utility.
To address issues 2 and 3, we're working on a second utility that installs BC4J runtime and provides a fix to the JSP compiler. We plan to post this second utility by the end of next week.
We do apologise for the problems you're having; please bear with us as we work on making it easier for you to deploy BC4J applications to OC4J.
Thanks

Hi, I have been trying desparately to deploy
a simple example JDeveloper application for months and months.
I HAVE NEVER BEEN SUCCESSFUL IN DEPLOYING ANYTHING.
I don't know much about webservers and I am relying
on the instructions from JDeveloper help and this website.
I have already tried Apache, and WebLogic
because there are instructions in the JDev help.
No luck.
Now I am trying to use OC4J on 9ias because there are instructions.
I have read the instructions about how to install a BC4J
app on OC4J about 25 times, but I can't get this thing to work.
It works fine inside of JDeveloper.
I create a BC4J project using the scott
schema (just the dept and emp tables).
Then I create an empty project for my JSP client.
I choose JSP Application from the web
objects and it connects to my BC4J project.
As I say, when I run it in JDeveloper, there is no problem.
In the instructions for installing BC4J
in OC4J, it first says install JDev 3.2.3 and OC4J.
This is done, and it tested fine.
Then it says to install the deployment software.
No problem.
But when I deploy the app according to the instructions,
it just hangs (like Rick Wang's program did).
The main.jsp page loads and displays correctly,
but when I click on the links to the DeptView.jsp
or EmpView.jsp it just hangs.
Here is the entire batch file I'm using
to start OC4J: cd c:\oracle_9ias\j2ee\home

The file al_BC4J.jar contains my application.properties file
and my connections.properties file, as well as my business components.
All of the files referenced in my classpath are
present in my c:\oracle_9ias\j2ee\home\lib directory.
I noticed that Raghu's classpath contains a file called jdev.jar
So does the classpath of another fellow who says
he was successful in deployment (his name is Jeffrey Jackson).
I searched my JDev_3.2.3 for this file and found it nowhere.
I also searched my OC4J home and my 9iAS for this file and
found it nowhere.
It is nowhere on my C:\.
Is this file necessary?
I will also try removing my application.properties file
and my connections.properties file from my BC4J .jar file
and put them in a separate .jar file at the root level (as Raghu did).
However, Jeffery Jackson did not do this and says he was
successfull in deployment.
***DO I NEED TO JAR UP ANY OF MY THE FILES FROM the JSP
FOLDER IN JDevHome\myhtml???***
***or place them in the classpath?***
I have read over all of the discussions at: http://technet.oracle.com:89/ubb/Forum2/HTML/008232.html

Can anyone help me?

How to deploy BC4J Substitutions?

Hi All,
I need help on deploying BC4j substitutions.
I have done some custom development for which I did some VO substitution.
Right now I have impoted substitution using jpximport utility refering to my .jpx file residing on my project file.
but in future if client want to deploy that on different server then how they can?
Do I need to copy this .jpx file on custom top and refer this file in jpximport?
Please Guide me.
Regards,
Adarsh

Substitutions are stored as site level customization in the JRAD repository. If you are creating a substitution for a VO, /oracle/apps/pos/server/TestVO then the substitutions will be stored in /oracle/apps/pos/server/custoizations/site/0/TestVO.
You can export this cusomization document in to an xml file and export it to a different instance. The easient way of maintainence is to club all the substitutions and store them in a single jpx file and use jpximport to import them all. One substitution line will be imported as one customization document.

Deploy BC4J on apache server

hi everyone,
on which web servers can we deploy BC4j?
Is creating jar files enough?What extra we have to do
We want BC4j to deploy on apache server,which i think does not support jsp.So what we need to do and how?
tnx in advance.

For JSP support on apache, download the OJSP product from OTN. It comes with instructions for configuring apache to run JSP pages.

Deploying BC4J on Apache

What are the steps one needs to follow while deploying BC4J to Apache as a middle-tier library? Any URLs where this is discussed?
Thanks for your help.

Hello ,
You just need to have the BC4J application
classes & the BC4J framework jar files
placed in the middle tier (
JBO , and have them included in your CLASSPATH.The BC4J classes
then could be accessed from a java application deployed on Apache.
This is similar to Local deployement.

Deploying BC4J on MIIS 4

Is it possible to deploy BC4J auction on Microsoft internet information server 4?
null

You should be able to deploy a JSP web application to any webserver that supports JSP 1.0 and Servlet 2.0 or later.
Make sure to deploy the runtime libraries needed by the app to the webserver's host and include them in the classpath for the webserver.
See your webserver doc for more information on setting its classpath.
For more info on deploying JSP web applciations, see the online help:

Problem in Connection pooling after deploying BC4J App Module as EJB

Hi,
We have deployed the application modules on standalone OC4J as stateful EJB session beans.
The problem is that with each user, the number of database connections seem to increase. This is making the application unscalable, which defeats the purpose of using EJB!
Can someone please suggest how to limit the number of database conections in this scenario?
Can this be solved by application module pooling? How can we use the PoolMgr to work with the session beans?
We have tried to invoke disconnect on the application module after calling methods(using appmodule.disconnect(true)) and reconnect (appmodule.reconnect()) on entering the method. This keeps the number of connections low and works the first time the method is invoked. But subsequently, it gives nullpointerexception when the Row is accessed in the JSP.
The exception we are getting is :
java.lang.NullPointerException
     at oracle.jbo.client.remote.ViewUsageImpl.getStructDef(ViewUsageImpl.java:241)
     at oracle.jbo.client.remote.ViewUsageImpl.findAttributeDef(ViewUsageImpl.java:275)
     at oracle.jbo.client.remote.RowImpl.getAttributeIndexOf(RowImpl.java:368)

     at supplier.sccPayCheq._jspService(_sccPayCheq.java:102)
     [SRC:/Supplier/sccPayCheq.jsp:44]
The Application module configuration (in bc4j.xcfg) is:
<AppModuleConfig name="SupplierAM9iAS">
<AppServerConnectionName>StandaloneOC4JConnection</AppServerConnectionName>
<AppModuleJndiName>Supplier.SupplierAM</AppModuleJndiName>

<java.naming.security.principal>admin</java.naming.security.principal>
<DtMiddleTierDeploymentProfile>ProjectMiddleTier.deploy</DtMiddleTierDeploymentProfile>
<ApplicationName>Supplier.SupplierAM</ApplicationName>
<DtDeploymentProfile>ProjectEJB.deploy</DtDeploymentProfile>
<DtCommonDeploymentProfile>ProjectCommon.deploy</DtCommonDeploymentProfile>
<JDBCDataSource>jdbc/ConnectionCoreDS</JDBCDataSource>
<jbo.server.internal_connection>jdbc/ConnectionCoreDS</jbo.server.internal_connection>
<jbo.ejb.txntype>local</jbo.ejb.txntype>
<jbo.doconnectionpooling>true</jbo.doconnectionpooling>
<ApplicationPath>ProjectEJB</ApplicationPath>
</AppModuleConfig>
The Datasource used (in $ORACLE_HOME/j2ee/home/config/data-sources.xml) is:
<data-source
          class="oracle.jdbc.pool.OracleConnectionCacheImpl"           connection-driver="oracle.jdbc.driver.OracleDriver"
          ejb-location="jdbc/ConnectionDS"
          inactivity-timeout="30"
          location="jdbc/ConnectionCoreDS"
          name="ConnectionDS"
          password="*******"
          pooled-location="jdbc/ConnectionPooledDS"
          url="jdbc:oracle:thin:@<IPADDESS>:<SID>"
          username="USER"
          xa-location="jdbc/xa/ConnectionXADS"
          max-connections="5"
          min-connections="1"/>

Can this be solved by application module pooling? How
can we use the PoolMgr to work with the session
beans?You can use a stateless checkout/checkin appmodule.
Take a look at the following help topics which explain this in good detail.
"About Application Module Pooling"
"About JSP Pages and Application Module Pooling"
The pool can help reuse the appmodule instance across requests thus reducing the number of concurrent db sessions.
