ClassCastException in deployejb tool

Hi,
We have installed Oracle 8.1.5 on Win NT.
We are trying to run the helloworld demo(sample EJB example) provided by Oracle.
But during the runnning the makeit batch file(which is provided by Oracle) we get a ClassCastException. The stack trace is as follows:
Exception in thread "main" java.lang.ClassCastException: com.sun.CORB
A.iiop.ORB at oracle.aurora.jndi.orb_dep.IRFinder.getObject(IRFinder.java:24) at oracle.aurora.jndi.orb_dep.IRFinder.initialReferences(IRFinder.java:78) at oracle.aurora.jndi.sess_iiop.SessionCtx.initialContext(SessionCtx.java:499) at oracle.aurora.jndi.sess_iiop.SessionCtx.<init>(SessionCtx.java:35) at oracle.aurora.jndi.sess_iiop.ServiceCtx.createSession(ServiceCtx.java:130) at oracle.aurora.jndi.sess_iiop.ServiceCtx.login(ServiceCtx.java:295) at oracle.aurora.server.tools.sess_iiop.ToolImpl.initializeSession(ToolImpl.java:101) at oracle.aurora.server.tools.sess_iiop.ToolImpl.parseStdArgs(ToolImpl.java, Compiled Code)
at oracle.aurora.server.tools.sess_iiop.ToolImpl.invoke(ToolImpl.java:121) at oracle.aurora.ejb.deployment.GenerateEjb.main(GenerateEjb.java:445)
We have configured the listener for IIOP clients. And also set the required environment variables as documented.
Has anyone encountered this problem.
Can someone PLEASE help us???
TIA,

Output of using Oracle8i "deployejb" tool

Hi,
To deploy the EJB successfully, Oracle recommends that we deploy their Sample EJB's, which ships with Oracle8i product,
before proceeding with our EJBs. This would help us verify the installation.
The sample EJB's are available at %ORACLE_HOME%\javavm\demo\demo.zip.When the demo.zip file is extracted, a
folder \examples\ejb\basic\helloworld, is created in the extracted path.The makeit.bat and runit.bat files in this folder
should run successfully to deploy the EJB in the DB.
When I attempt to execute, makeit.bat doesnot run properly.The output is pasted here for your reference.As you may notice,
ClassCastException occurs, when a call is given to deployejb, through the makeit.bat file.

I would like to post what I did in fact get to work.
I took the suggestion to replace single-quotes with double-quotes. What also DID seem to help things was:
1. removing all XML entities from my markup, even properly escaped ones (like & or  )
2. ensuring that:
<xsl:variable name="_XDOFOPOS2" select="number(1)"/>
<xsl:variable name="_XDOFOTOTAL" select="number(1)"/>
appeared in the table (before anything else, still not sure what these are controlling or internal Oracle logic is happening).
I am still not 100% (or even 60%) sure this problem won't crop up if we have to modify our template, but through going through our original markup and adding it to a file that "works", table by table, and
assessing any errors, our reporting now works.
However, having entities (especially ampersand, or the non-breaking space [used as a placeholder for NULL database values to ensure the table-cell gets created]) would be useful.
Thanks for your comments.

"Memory" If you are trying to look at the memory usage of an OS process connected to Oracle you have an issue you need to be aware of, namely, most UNIX/Linux utilities cannot distinguish between private memory used by a process and shared memory. Since the SGA exists in shared memory the process memory statistics can show as using huge amounts of memory and the sum of all your Oracle connected processed can far exceed the available memory because of this double counting.
HTH -- Mark D Powell --
I missed that you had posted two separate questions. I will just answer in one. The questions I posted were about what it is you want the script to provide you and what value each column in the display has. I would point out that if you have issues looking at the OS level is unlikely to identify the problem in many cases. You may not see a process with extremely high cpu or memory at the OS level. The problem could be lock waiting or latch waiting. You will only be able to determine this by looking in the database. That is not to say that sometimes a problem session will not show up with high cpu only that in many cases the problem may be elsewhere. Eventually you are going to have to look in the database at the session so why not start there. After all top/topmonitor etc ... already exist at the OS level to find the high cpu, io, memory sessions. To find and fix database session issues you have to eventually connect to the database and high cpu, memory, and io sessions can all be found with queries.

Deployejb : Oracle 8.1.6 : Errors compiling the communication stubs

Hi,
I was able to deploy EJB using JDeveloper 3.1 in the Oracle 8i (1.1.6) DB.However, when I try it manually, it is giving errors.
I was able to use deployejb tool succesfully with Oracle 8.1.5 DB.Is there some problem with Oracle 8.1.6 DB?
This is output, I am getting :

Use of chmod in sess_sh tool

Hi,
While trying to use the chmod command in sess_sh tool, I could not see its effect.
I had deployed my EJB using deployejb tool.
The published Object in the Session Namespave under test Publishing Context is RentalEJBRemote (i.e /test/RentalEJBRemote)
I try running my client with user/password as sandeep/sandeep.It works fine.
Now, I want to revoke the execute right, so that when I try to activate the remote (Home) object, by calling the lookup method, I should get a NO PERMISSION message
I use the following sequence of commands after that :
1. sess_sh -user sandeep
-password sandeep
-service sess_iiop://sandeep:2481:oracle8i
2. $ cd test
$ ls -l shows
READ WRITE EXEC OWNER SCHEMA
PUBLIC SANDEEP PUBLIC SANDEEP SYS
3. Removing the execute permission of sandeep
for this Published Object
$ chmod -e sandeep RentalEJBRemote
(No errors reported)
4. $ ls - l still shows ....
READ WRITE EXEC OWNER SCHEMA
PUBLIC SANDEEP PUBLIC SANDEEP SYS
5. When, I try to access/activate the Home object, I am still allowed to do so.
Hence, I am not able to see the effect of chmod.
Please advise.
TIA

Hi,
The guide says you would need to use
chmod -x sandeep RentalEJBRemote , i.e. use -x instead of -e
The moment I do this, I get an exception trace

Please advise.

Thanks Murray, I worked through the suggested troubleshooting remedies and it wasn't solving the problem, but I was learning quite a lot about the functionality of DW8 as I did it
Then I uninstalled the program and re-installed it and thankfully the JavaScript themed alerts have stopped.. I haven't reinstalled the DMX extensions yet, but previously de-selecting them hadn't made any difference.
Very grateful for your help. I'm up and running again.......

ClassCastException: CollaxaConnNode during initialization of JDev 10.1.3.2

I am getting the following exception during startup/initialization of the public 10.1.3.2.
This is on Windows using Java 1.5.0.07. After I acknowledge the exception in the
popup the startup seems to continue normally(?).
I found an earlier posting on this subject from the 10.1.3.1 timeframe and there was
some discussion of a BPEL extension. I'm just unzipping the publically available
distribution. Nothing fancy.
Here is the exception. Any ideas about how to get rid of this annoyance?

I meet the same issue in eclipse exporting Javadoc. Maybe "splitindex" prevent the build to an end. I cancel the choise of "Generate index" in basic option of "Configure Javadoc arguments for standard doclet." Then the build is normally over. Or a custom doclet may also can avoid this problem.

IOException using deployejb

Hi,
I have a problem loading EJBs into Oracle JVM using the deployejb tool.
I am using Oracle 9.0.1. on Windows 2000.
In our project we are deploying several EJBs
using a batch file where the command
deployejb -u scott -p tiger -s sess_iiop://myserver:2481:DBSID -descriptor G:\xml\<BeanName>.xml -temp temp G:\install\jarfiles\<BeanName>Source.jar -generated G:\install\jarfiles\<BeanName>Source_generated.jar -keep -oracledescriptor G:\xml\<BeanName>_oracle.xml -republish
is called. This works for several beans (about 20).
For the next bean, I get something like
Entwicklungsdeskriptor wird gelesen...fertig
Komm-Stubs werden generiert...fertig
Stubs werden kompiliert...
IOException during compilation: CreateProcess: javac -d "G:\install\deploy\temp" -classpath <MyClasspath> "G:\install\deploy\temp\<BeanName>.java" "G:\install\deploy\temp\<FirstBeanName>DataHelper.java
where <FirstBeanName> is the name of the first bean that was installed with the batch.
It seems to have something to do with the temp directory (resp. the number of files in it),
because if I delete the temp directory and
try to the deploy the bean again, it works.
Does anybody know why this happens?
Thanks for your help.

Torsten,
Oracle Corporation (in my opinion) obviously, initially thought
that they can implement any type of software through their database
server. After a long time of trying to convince us that their EJB
container is good, they finally admitted that it wasn't (by acquiring
OrionServer and calling it OC4J ;-) So yes, now people like us are
(slightly) f***ed, and Oracle Corporation are saying that OC4J is
good! At least you can say that Oracle Corporation are consistent!
First they pushed Oracle Application Server (OAS). Then they
admitted it was sh*t and pushed Internat Application Server (IAS).
Again, they admitted it couldn't cut it, so they pushed 9iAS. As
usual, this gave way to OC4J. But hey, I guess they can keep doing
that because we keep coming back for more punishment! (Well if it
works for Micro$oft, it can work for Oracle, too!)
Our CTO also said (after we were well into development using the
9iAS EJB container) to stick with it and not move to OC4J. However,
when we realized (like Oracle did) that we just couldn't get our
app to work with 9iAS, we also realized we had to move.
Just my two cents worth (and in no way a reflection of my
employer's opinions regarding Oracle Corporation).
Cheers,
Avi.

Problem with continue in a for loop

- This is a real bug in the compiler, obviously. I wonder if I haven't meet it already, or something similar. Maybe you should report it.
- The problem is that your code is incorrect anyway: the branch with continue doesn't return a value, so cannot be used in the list building. Well, at least that's what I suppose which confuses the compiler. You can try and return null (which will be discarded) instead of using continue.
- But your code can be much more efficient, compact and perhaps even more readable, using the powerful JavaFX sequence comprehension:
var seqMixed = [ 1, "one", Text { content: "Ichi" }, Circle {}, 2, "two", Text { content: "Ni" } ];
println(seqMixed);
var seqFiltered = seqMixed[ obj | obj instanceof Text ];
println(seqFiltered);
seqFiltered = seqMixed[ obj | not (obj instanceof Text) ];
println(seqFiltered);

Problems deploying a simple EJB

I am trying to deploy a simple EJB on the 8.1.5. The bean only owns a single method that needs a unique parameter.
No problems with compilation of source bean, home and remote interfaces, whatever the type of this parameter is.
But when I try to deploy the jar on the server, I only succeed if the parameter of my method is a simple type (int, String ...).
If I try the same passing a complex type (here a oracle.xml.parser.v2.XMLDocument type), I encounter this message from the deployejb tool :
Generating EJBHome and EJBObject on the server...
Compilation errors in oracle/aurora/ejb/gen/test_myFluxInsert/EjbObject_FluxInsert:ORA-29535: source requires recompilationjava/lang/Object: Authorization error for referenced class Oracle/xml/parser/v2/XMLDocument.java/lang/Object: Authorization error for referenced class oracle/xml/parser/v2/XMLDocument.oracle/aurora/ejb/gen/test_myFluxInsert/EjbObject_FluxInsert:50: Class oracle.xml.parser.v2.XMLDocument not found in type declaration.
public java.lang.String insereFlux (oracle.xml.parser.v2.XMLDocument arg0)
^ Info: 3 errors
And if I use an int instead of the XMLDocument parameter, everithing's right.
Can anybody submit a no-paranormal solution ?
Thanks.
GH

Parameter passing in EJB must implement Serializable. One way to solve this is:
1. Define a new class which implements
Serializable.
2. Place whatever you want to pass inside
this class.
3. Now use the new class as your parameter.
eg.
public class Params implements java.io.Serializable {
String p1;
XmlDocmuent xdoc;,
etc, etc
Your program now have to use the class Params for parameter passing.
Hope this helps.

Class not Found Exception while running an EJB

I have created and published a EJB in Oracle 8i (in a particular
schema) by running the deployejb tool supplied. The ejb was
published successfully. On running the client program I get an
error saying that the mybeans's HomeHelper class cannot be
found. This error occurs when there is a lookup to the home
interface of the bean. The exception thrown says Reasons are
unknown. On checking the objects of type 'JAVA CLASS' I found
that the homeHelper class object had been created automatically

found exception and what can I do to correct it. ?

Problems building JavaDoc of classes using Hibernate/javax.persistence

Hallo!
I am trying to create the javadoc of classes that use hibernate. First it starts of with error messages like
[javadoc] SubmissionSet.java:40: cannot find symbol
[javadoc] symbol: class Table

[javadoc] Employee.java:8: package javax.persistence does not exist
[javadoc] import javax.persistence.JoinColumn;
[javadoc]                         ^Afterwards it gets even strange with exceptions within javadoc like:

Thanks in advance

See [http://forums.sun.com/thread.jspa?threadID=5333060&tstart=0]. In general, if you use third-party libraries in your code, you should include these libraries in Javadoc's classpath option when generating documentation.
