OC4J EJB QL MAX KeyWord Error!

Encountered "max" at line 1, column 8.
Was expecting one of:
"OBJECT" ...
"DISTINCT" ...
"IdentificationVar" ...
EJB QL statement : 'select max(m.idx) from MessageCache m where m.owner=?1 and m.sender=?2'
EJB QL method : public abstract java.lang.Long EJB.ChatDataEJBCBean.ejbSelectMaxIndex(java.lang.String,java.lang.String) throws javax.ejb.FinderException
WHY?

Thank First!
Yes!The JDeveloper VER Is 10.1.3.2
I Post The ejb-jar.xml Part Of Content:
<query>
<query-method>
<method-name>ejbSelectMaxIndex</method-name>
<method-params>
<method-param>java.lang.String</method-param>

NI MAX throughput error and Camera attribute out of range

I recently purchased a Point Grey Grasshopper3 camera, it seems to work fine in the Fly Cap software point grey provides, but I get an error in NI MAX when I try to do a simple grab (shown below). This error shows up every time I try to grab an image the first time after opening NI MAX, even though throughput is set to the max. Then I change the throughput max under device control to any number around the max of 125000000, and the camera works fine for MAX. It will grab images as much as I need. Then I save the camera, exit MAX, open MAX again, it shows my saved settings, I go to grab images and I get the error again. So I change the range to whatever number and it works again in the same session in MAX.
I did have a point grey Zebra2 working fine, and was using it in my LabVIEW program with IMAQdx to acquire images. When I try to use grasshopper3, LabVIEW returns an error of camera attribute out of range from the camera configuration VI. The VI's I am using to test the camera is just open camera, configure acquisition, start acquisition, get image, unconfigure acquisition, and close camera from IMAQdx. I did twice open MAX, change throughput, save camera, close MAX without grabbing an image, and then was able to acquire images in LabVIEW on the first run. Then I would run the VI again and it would return the error for camera attribute out of range. I have changed the packet size, resolution, and frame rate of the camera with out noticing a difference in the errors.
Since I am able to stream images from the camera in point greys fly capture, and in MAX after toggling the throughput setting, it leads me to believe there is some sort of MAX/LabVIEW error preventing me from capturing the images.
Any ideas? Has anyone else had this issue with MAX and LV?
Solved!

It looks like Point Grey cameras have shown this error before based on out of date firmware. See this link for one such instance. I would monitor the camera file (*.icd) located in the IMAQdx data folder in Public Documents to see if the actual value is being overwritten after the camera configuration is saved in MAX. There is a chance that the GigE .XML file that is transferred from the camera is overwriting these values to the unacceptable value. See this link for a KB regarding this error, which leads me to believe this may be the issue.

Starting OC4J instance 'OC4J_Wireless'...done.

Just ran into this exact same issue. We also resolved it by modifying our /etc/hosts.
Our /etc/hosts used to have its hostname specified this way:
123.123.123.12 hostname hostname.dom.com
We changed the order to the last two items to this:
123.123.123.12 hostname.dom.com hostname
Apparently the services are instantiated using the fully-qualified hostname.

The server deploy EJB but I run EJB Client program,The error msg is can't find JNDI

Hi all:
I am using Weblogic 6.1/SP2. I use the console to start
server and deploy EJB jar,from the msg I see my EJB jar
been deployed. When I run EJB Client program, the error

I check my ejb-jar.xml amd weblogic-ejb-jar.xml are fine.
Last week I did deploy EJB and ran the client both
suceessful. Any ideas, Thank you.

Sabha:
Thank you for your help info, I soloved the problem.
The problem is the ejb jar was deleted(I don't why)
then System Admin to deploy EJB jar from Admin console.
After that everything is fine.

you can view the jndi tree of the server from the console (right click

name.

Hi Albert,
I would double check to make sure the EJB was indeed deployed (check
server log). What message did you see that leads you to believe itwas
successfully deployed? Also, verify the JNDI name you are lookingup in
your client matches the JNDI name for the EJB. If this doesn't solve
the problem, please post the error message and stack trace you are
seeing on the client.

David,
config.properties is used only by the client.jpr. Not by the Web.jpr
config.properties file has been provided for looking up resources[EJB, Datasources] from JNDI tree of OC4J.
Since servlet and other resources are in the same container[Single JVM] there is no need to specify the username, password, Provdier_URL at the time of lookup.
Look at the init method of EJBHotelServlet.java :
Context ctx = new InitialContext();
// Acquire the home interface handle and call the create
//method on it
homeInterface = (HotelSystemHome)ctx.lookup("OneEJBHotel");
Here servlet looks up EJB without any authentication information, as servlet and EJB are in the same container.
Whereas Stand alone client is running outside the OC4J.
So the stand alone client need to authentcate itself for looking up the resources from JNDI tree.
Look at the getHotelSystemBean method of EJBHotelSample.java :
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, prop.getProperty("Initial_Context_Factory"));
env.put(Context.SECURITY_PRINCIPAL, prop.getProperty("Principal"));
env.put(Context.SECURITY_CREDENTIALS, prop.getProperty("Credential"));
env.put(Context.PROVIDER_URL, prop.getProperty("Provider_Url") );
// Associate the properties with the context
Context ctx = new InitialContext(env);
// Acquire the home interface handle and call the create
//method on it
homeInterface = (HotelSystemHome)ctx.lookup("OneEJBHotel");
Here stand alone client looks up EJB by specifying the authentication information, as stand alone client and EJB are running in different JVM's.
Hope this helps...
Cheers

EJB- HRS and Client Error

This is the error i get when i do the 1st part of the Human resource reservation in Jdeveloper tutorial:
what could cause the error:
C:\jdeveloper\jdk\bin\javaw.exe -ojvm -XXdebug,quiet,port1033 -classpath C:\jdeveloper\jdev\mywork\MyHRApplication\EJB-Tier\classes;C:\jdeveloper\jdev\lib\jdev-rt.jar;C:\jdeveloper\j2ee\home\lib\activation.jar;C:\jdeveloper\j2ee\home\lib\ejb.jar;C:\jdeveloper\j2ee\home\lib\jaas.jar;C:\jdeveloper\j2ee\home\lib\jaxp.jar;C:\jdeveloper\j2ee\home\lib\jcert.jar;C:\jdeveloper\j2ee\home\lib\jdbc.jar;C:\jdeveloper\j2ee\home\lib\jms.jar;C:\jdeveloper\j2ee\home\lib\jndi.jar;C:\jdeveloper\j2ee\home\lib\jnet.jar;C:\jdeveloper\j2ee\home\lib\jsse.jar;C:\jdeveloper\j2ee\home\lib\jta.jar;C:\jdeveloper\j2ee\home\lib\mail.jar;C:\jdeveloper\j2ee\home\oc4j.jar;C:\jdeveloper\lib\xmlparserv2.jar;C:\jdeveloper\lib\xmlcomp.jar Samplehr.hrAppClient

Try below solution :
1. Take a copy of HReports.jar (Updated file) from the FR Report Server instance.
2. Bring the copied file to the User's Local Workstation and replace it with the one located under %HYPERION_HOME%\products\biplus\lib
3. Re-launch the FR Studio.
4. Open any of the FR Reports and now it can successfully print preview the FR Reports from the FR Studio.
above error happens if any FR patch is installed on FR server but not on client. So try above and if it does not resolve then make sure server and client has same patch level.

EJB Entity/Session Transaction error

I am getting an error from a Session EJB trying to update two distinct Entity EJB's. From the session bean I open a transaction and create two entity objects. But immediately after trying to create the first one I get the following message:

I am using JDeveloper 10.1.2.1.

I am using CMP Entity beans. These have their methods specified as "Supports" and the Session Bean (Stateless) has its method as "Required".
I am using the container within the embeded OC4J server for debuging.
The transaction is created within the Session Bean as:
// Get a new transaction instance from session context
UserTransaction ut = sctx.getUserTransaction();
try {
// begin transaction
ut.begin();
// Current time
Timestamp currentTime = new Timestamp(new Date().getTime());
// Insert record in CWUsuarios
CWUsuarios newCWUsuarios = getCWUsuariosHome().create(null,
cwUsuario.getLogin(), cwUsuario.getPassword(),
cwUsuario.getNombre(), cwUsuario.getApellidos(),
currentTime, currentTime, cwUsuario.getActivo(),
cwUsuario.getRoot(), cwUsuario.getIdperfil());
// Insert record in CWPreferencias
CWPreferencias newCWPreferencias = getCWPreferenciasHome()
.create(newCWUsuarios.getIdusuario(),
cwPreferencias.getCodigoidioma(),
cwPreferencias.getIdtema(),
cwPreferencias.getNregslistados());
however after returning form the getCWUsuariosHome().create method i get the specified error message.
Thanks.

Problems with OC4J EJB deployment and the data-sources.xml file

I am running 2 Windows 2000 Machines one with the 8.1.7 database another with iAS 1.0.2.2.1 and OC4J.
I am trying to deploy a 3rd party EJB-based application whic seems to have deployed successfully except when I try to test the EJB deployment via a jsp it can't connect to the database, giving the error:

Please advise.
I have followed the instructions in 'EJB Primer' and 'Using Oracle9iAS Containers for J2EE' to no avail. And I can't find any meaningfull data-sources.xml samples. I have been struggling with this for some time.
Is there any other file, do I need to bind anything?
I'd appreciate your assistance.
Thank you
Louiza

Hi Louiza,
Show us your web.xml and ejb-jar.xml files as well as your
data-source.xml file.
Thanks,

Oc4j auto deploy cause toplink error

Hi,
We are using the OC4j 9.0.3 with toplink 4.x (latest)
We are using the SessionManager to load the mapping descriptor file
I start the appserver and everything is fine.
Then I compile the servlet. When I reload the page I get a missing descriptor
error ?
If I restart the appserver everything works fine. Is there a way withoug
restarting the app server ?
Thanks
Ratna

Hi Vidya,
Sounds like a classloader/classpath issue. Since I'm not sure exactly how you are deploying the servlet I'd recommend first adding a <library path> entry to the application.xml file that points to the location of the sessions.xml file. The alternative is to include this file in the WAR with the servlet. Note that the latest Oracle9iAS TopLink version is 9.0.3 and is available for download from the OTN site (http://otn.oracle.com/software/products/ias/devuse.html). Included in the download are sample TopLink applications (EJB's, Servlet/JSP's) that run on OC4J.
Hope this helps.
Thanks,
Pete Farkas

Initial Context Factory for same OC4J EJB access in 10.1.3.1

What should the INITIAL_CONTEXT_FACTORY be set to when you try to access an EJB from within the same OC4J instance? Should it be:
a) ApplicationClientInitialContextFactory
b) RMIInitialContextFactory
c) Nothing at all
d) Something else completely
I ask because I am try to move from 10.1.3.0 to 10.1.3.1 and I have a thread spawned during startup that is unable to access the EJB
2007-05-25 07:22:50.862 WARNING J2EE RMI-00009 Exception returned by remote server: {0}
07/05/25 07:22:50 Unknown service: MySessionHome
javax.naming.NameNotFoundException: MySessionHome not found
It does not set the INITIAL_CONTEXT_FACTORY because it has been my understanding that this is not necessary. Did something change in 10.1.3.1?

Has anyone found a solution for this problem? I tried adding the following entry to my orion-application.xml file with no luck. I was able to fix the problem by adding commons-digester.jar,commons-logging.jar, and log4j-1.2.15.jar to the /BC4J/lib folder on the server. Unfortunately this fix caused errors when trying to launch the BPEL console. Any help would be greatly appreciated.

EJB QL method parsing error

I have an EJB-QL finder which uses a java.sql.Timestamp as the third argument. When deploying on 9.0.3 (production + a patch), I get an error "Invalid type for expression (B.startDate = ?3)". The ejb-jar.xml file lists ?3 as java.sql.Timestamp, and the reported method signature also uses java.sql.Timestamp as the third argument. (StartDate is a DATE field in the database).
Any clues?
Steve
PS trying to keep this short due to 1k limit...

I think this falls under the general (I think silly) restriction imposed by OC4J that they insist longs are passed into finders instead of perhaps the Timestamps actually returned by the finders....
I can't find anywhere in spec that spells out this restriction, except for the line cited in other messages that say "longs should be used", i.e. a recomendation, not a restriction, rather then "must" or "not supported" as the other restrictions in that same section clearly state.
In fact the next line in the spec says the longs should be produced by java.util.Calendar... Is that going to be enforced by OC4J? :)

EJB Hotel Sample Application - error running client

Hi
I am trying to run the GUI client interface in the EJB Hotel Enquiry and Reservation Application (using a single EJB). I have deployed the EJB jar file and had no errors but when I run the GUI client I get the following error whilst trying to read the list of hotels:
Error while invoking EJB procedure :RemoteException :
com.evermind.server.rmi.OrionRemoteException: Invocation error: java.lang.NoSuchMethodException; nested exception is:
java.lang.NoSuchMethodException
Could anyone please suggest where to start looking ?
TIA
Trevor

Hi,
I am able to run this sample successfully. Can you try bouncing OC4J and then run the client application again ? Let me ]
know if that works.
Cheers,

How to Migrate OC4J EJB Web service to Weblogic

Hello,
We have a J2EE app developed under OC4J that needs to be migrated to weblogic 10.x. It uses web services mapped to EJB's with the oracle.j2ee.ws.SessionBeanWebService class, example setup:
<servlet>
<servlet-name>CreditCardManager</servlet-name>
<servlet-class>oracle.j2ee.ws.SessionBeanWebService</servlet-class>
<init-param>
<param-name>jndi-name</param-name>
<param-value>CreditCardManagerBean</param-value>
</init-param>
</servlet>
Can someone point me to any docs on how to create the equivalent objects in Weblogic?
Thanks,
Leor

Microsoft webservices uses HTTP sessions to maintain state. That means that the webservice sends a token to the client to be passed back on subsequent calls.
Unfortunately, the webservice control in 8.1 doesn't know how to send the session token back to the MS webservice. The webservice control knows how to talk SOAP only. It doesn't know about session tokens. The reason for this is the different protocols available to transmit SOAP. Most of them are not HTTP session aware.
Workshop webservices uses conversation ID's that are contained within the SOAP header to maintain state. That way, we don't have the dependency on the session state for maintaining state.
The way to handle Microsoft's stateful webservice implementation is to create a custom webservice control that uses an HTTP client. Query the HTTP client for the session cookie. Store the session token and send it with subsequent calls to the MS webservice.
Thanks,
