Bean not remain in my session?
i made this code for 2 pages, wanting to use a bean in both sites...the problem is it is created on the index page, but when i try to recall it on the 2nd, it creates it again...any tips on this? here's the code of the pages:
index.jsp
<jsp:useBean id="bean" scope="session" class="bean.initiate" />
<% int c =bean.start(10,3); %>
<HTML>
<HEAD>
<TITLE>Construct Ballots</TITLE>
</HEAD>
<BODY>
<H1>Construct Ballots</H1>
<FORM NAME="form1" ACTION="ShowBallot.jsp" METHOD="POST">
<INPUT TYPE="HIDDEN" NAME="buttonName">
<label>
<input type="text" name="amount">
</label>
<INPUT TYPE="BUTTON" VALUE="Make Ballots" ONCLICK="button1()">
</FORM>
<SCRIPT LANGUAGE="JavaScript">
<!--
function button1()
document.form1.buttonName.value = "Constructing Ballots..."
form1.submit()
-->
</SCRIPT>
</BODY>
</HTML>
ShowBallot.jsp
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>
<jsp:useBean id="bean" scope="session" class="bean.initiate" />
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<HEAD>
<TITLE>Determining Which Button Was Clicked</TITLE>
</HEAD>
<BODY>
<p><%= request.getParameter("buttonName") %>
<% String a= request.getParameter("amount"); %>
<%int input= Integer.parseInt(a); %></p>
<p><%int g=bean.confirm();%> </p>
<p>This is one example of a ballot constructed:</p>
<p><%=g %> </p>
<p> </p>
</BODY>
</html>
How do you know it creates the bean again?
The code looks ok to me.
What does the bean.initiate class do?
One way of confirming if it is the same session is to use
Session id = <%= session.getId() %>
It should be the same on both pages

How to instantiate App Mod in bean not tied to a specific page or session
I have come to the conclusion that I can't initialize the BC4J framework (e.g. initialize properties for the connection pool) until I create an instance of an App Mod. How can I do this in a static initializer block of a bean that is not tied to any particular page or user session or pageeContext?
I am trying to share the database connection pool across not only app modules but some of our pages that need to connect to the db but do not have app modules on them. But when I try to get the ConnectionPoolManager instance, it fails (UNLESS a page with an App Module on it was loaded first). If I try to get the instance first I get a nullpointer exception. Important note: I am in my own connection wrapper class so I do not have a session or pageContext.
I do this in my static initializer block of my class:
poolManager = ConnectionPoolManagerFactory.getConnectionPoolManager();
(this throws a null pointer exception)
and I've traced the error to this line in the ConnectionPoolManagerFactory getting null back:
String s = PropertyMetadata.PN_POOL_MANAGER.getProperty();
I suspect it is because the oracle.jbo.PropertyManager.loadProperties has not been run yet. The javadocs says: "This class is used at
framework initialization time to choose values for the various properties".
So, my questions are:
1) If I have to invoke an app mod instance to make this work....What's the simplest way to create an app mod instance from a bean that is
not tied to a session?
or 2)
1) Is there a way that I initialize the framework from my bean without instantiating an app module?John,
First of all, thanks for the response. You provided workable answers for both possible approaches and I appreciate that. However, I am having a problem with both due to my unique situation....1) we are using JDeveloper 3.2 which doesn't have the SessionCookie class so while I can get an instance of an App Module, I can't do the next part which apparently is necessary to initialize the framework...2) I tried your other recommendation about calling the System.SetProperty method for the connection pool manager class and it worked!.....however, it instantiates the connection pool with default settings and not with my pool properties in my jboserver.properties file which I need.
Norm
Hi,
Please see the discussion thread at:
Re: Maintaining the state between http requests
for more information about using the BC4J connection pool from an external Object.
So, my questions are:
1) If I have to invoke an app mod instance to make this work....What's the simplest way to create
an app mod instance from a bean that is not tied to a session?.
You can use the oracle.jbo.common.ampool.PoolMgr directly to find/create a pool. For instance:
ApplicationPool pool = PoolMgr.getInstance().findPool(
"Mypackage1ModuleLocal" // pool name
, "mypackage1" // config package name
, "Mypackage1ModuleLocal" // config name
, null); // additional properties
SessionCookie cookie = pool.createSessionCookie(
DUMMY_APPLICATION_ID // application id
, DUMMY_SESSION_ID // session id
, null); // additional properties
cookie.useApplicationModule();
cookie.releaseApplicationModule(
true // checkin
, false); // manageState
pool.removeSessionCookie(cookie);
or 2)
1) Is there a way that I initialize the framework from my bean without instantiating an app module?.
Please see the original post referenced above.
Hope this helps.

OK, maybe I'm oversharing, but I want to be thorough. Note I asked this question a different way using very different code.
Here's my jsp file - myq.jsp
<%@ page language="java" import="java.util.*,com.serco.inquire.*" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="inq" tagdir="/WEB-INF/tags" %>
<inq:displayCollection>
<jsp:attribute name="mgr">Chris Novish</jsp:attribute>
</inq:displayCollection>Here's displayCollection.tag used by that jsp:
<%@ tag body-content="scriptless" import="com.serco.inquire.*" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ attribute name="mgr" required="true" %>
<jsp:useBean id="irc" scope="session" class="com.serco.inquire.IrCollection">
<jsp:setProperty name="irc" property="mgrid" value="${mgr}" />
</jsp:useBean>
${irc.size} | ${irc.mgrid}Here's the java class IrCollection (used as a bean in the tag):
package com.serco.inquire;
import java.sql.*;
import java.util.*;
public class IrCollection {
public ArrayList iRecords = new ArrayList<InquireRecord>();
public int size;
public String mgrid;
public irCollection() {
super();
public void populateCollection() {
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String filename = "inquire.mdb";
String database = "jdbc:odbc:Driver={Microsof Access Driver (*.mdb)};DBQ=";
database+= filename.trim() + ";DriverID=22;READONLY=true}";
Connection con = DriverManager.getConnection( database ,"","");
Statement s = con.createStatement();
s.execute ("SELECT * FROM inquiries WHERE manager = '" + this.mgrid + "'");
ResultSet rs = s.getResultSet();
int cur;
while (rs.next()) {
cur = rs.getRow()-1;
InquireRecord localIR = new InquireRecord();
int curID = rs.getInt("ID");
localIR.setID(curID);
String cursub = rs.getString("submitter");
localIR.setSubmitter(cursub);
this.iRecords.add(cur, localIR);
con.close();
this.size = iRecords.size();
catch (Throwable e) {
System.out.println(e);
public int getSize () {
return this.size;
public void setMgrid(String datum) {
this.mgrid = datum;
this.populateCollection();
public String getMgrid() {
return this.mgrid;
}and here's the InquireRecord java class used by IrCollection:
package com.serco.inquire;
public class InquireRecord {
private int ID;
private String submitter;
public InquireRecord() {
super();
public InquireRecord(String asubmitter) {
this.submitter = asubmitter;
public int getID(){
return this.ID;
public void setID(int datum) {
this.ID = datum;
public String getSubmitter() {
return this.submitter;
public void setSubmitter(String datum) {
this.submitter = datum;
}The JSP does this: set the mgr variable, which is passes to the tag, the tag then creates an instance of IrCollection using that mgr variable. (Yes, putting that populateCollection() method call in the setMgrid() method is probably Bad Practice, but it works, usually). The IrCollection objects builds an ArrayList of InquireCollection objects from an Access database. It then sets it's size property based on how many InquireCollection instances it put into the ArrayList. Once that's all done, the tag spits out 2 things: The size property and the mgrid property.
When I view the JSP, it gives me 0 for the size and Chris Novish for the mgrid.
I think this could be one of the following:
*Not finding any matching records of the database
*Not actually executing the populateCollection() method
*some how forgetting the information it put into that ArrayList?
I"m sure there's another possibility, but I don't know.
Here's what gets me. Here's a test class I made called TestCollection:
{code}package com.serco.inquire;
import java.util.*;
import java.text.*;
public class TestCollection {
public static void main(String[] args) {
IrCollection myCollection = new IrCollection();
myCollection.setMgrid("Chris Novish");
System.out.println(myCollection.getSize());
System.out.println(myCollection.getMgrid());
}{code}
if I run that I get a size of 4 and a mgrid of Chris Novish.
Same data in, and it works as expected.
So... why won't JSP do it?You have defined a session scope for that bean. You have to make sure that the bean is instantiated by this jsp and not earlier. If the bean is located in the session because it was set earlier, then the body tags within useBean are not evaluated.
Look here - http://java.sun.com/products/jsp/tags/syntaxref.fm14.html#8865
An easy way to test it would be to change the scope of the bean to request.

EJB 3.0 Stateful bean not saving state while Stateless bean is !!!
My Stateless bean is as follow:
package test;
import javax.ejb.Stateless;
@Stateless(mappedName = "StatelessBean")
public class StatelessBean implements StatelessBeanRemote {
int counter;
public void increment(){
System.out.println("Stateless counter value:"+counter);
counter++;
My Stateful bean is as follow:
package test;
import javax.ejb.Stateful;
@Stateful(mappedName = "StateFulBean")
public class StateFulBean implements StateFulBeanRemote {
int counter;
public void increment(){
System.out.println("Stateful counter value:"+counter);
Client is as follows:
package test;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
public class TestClient {
public static void main(String[] args) {
Hashtable hashtable = new Hashtable();
hashtable.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
hashtable.put(Context.PROVIDER_URL, "t3://localhost:7001");
InitialContext ic;
try {
ic = new InitialContext(hashtable);
StateFulBeanRemote stateFulBeanRemote = (StateFulBeanRemote)ic.lookup("StateFulBean#test.StateFulBeanRemote");
stateFulBeanRemote.increment();
StatelessBeanRemote statelessBeanRemote = (StatelessBeanRemote)ic.lookup("StatelessBean#test.StatelessBeanRemote");
statelessBeanRemote.increment();
} catch (Exception e) {
e.printStackTrace();
The output i am getting after running the client twice is as follows:
//first time
Stateful counter value:0
Stateless counter value:0
//second time
Stateful counter value:0
Stateless counter value:1
Shouldn't the counter values be incremented in case of Stateful bean and remain the same for Stateless bean. But the output that I am getting is the complete opposite !!!
Can anyone please explain this confusing behavior of stateless and stateful ejb 3.0 beans.868664 wrote:
Can anyone please explain this confusing behavior of stateless and stateful ejb 3.0 beans.It is very simple: a stateless bean is ASSUMED to be stateless; you cannot keep state in a stateless bean as a contractual rule. That doesn't mean that you will fail to keep state in them at least for a little while, they are still only Java objects. Generally stateless EJBs are pooled, so you may get the same instance each time you use such an EJB, but you may just get another one. It is not dependable and the rules say don't do it - so don't do it.
A stateful bean is tied to a single client, and so can be used by a client to keep state in it. Since You are running the client application twice you are operating with two different clients and so you will get a new stateful bean each time and your code will keep printing 0. However there is also a bug in your code:
public void increment(){
System.out.println("Stateful counter value:"+counter);
}You are not incrementing anything. -
WebUtil: oracle.forms.webutil.host.Host bean not found
Hi. This is my first attempt using WebUtil. The following code is in my When-New-Form-Instance trigger:
client_host('N:\TTMS\ITS\vbasic\compiled\MenuUpdate.exe');
This is the error I receive:
oracle.forms.webutil.host.Host bean not found
I've included my formsweb.cfg below for your reference. Note that the application is using the [ttmsmenu] configuration.
Thanks in advance for your help with this problem.

I was running this form out of Form Builder 10g. At some point I changed the Application Server URL (Edit => Preferences => Runtime menus) from:
http://ssbuechl2.div16.ibm.com:8889/forms/frmservlet?config=ttmsmenu
to:
http://ssbuechl2.div16.ibm.com:8889/forms/frmservlet?
So my customized configuration with all the WebUtil references was not being referenced and I was getting the error.

Oracle.forms.webutil.file.FileFunctions bean not found. WEBUTIL_FILE.FILE_D
Hi guys,
I have updated my AS and DS to 10.1.2.3 and downloaded Wbutil 1.6 update 10.
I configured all the .cfg files as mentioned in the documentation when I launch a test form with config=webutil and a webutil functionality in it then i am getting following error -
oracle.forms.webutil.file.FileFunctions bean not found.
WEBUTIL_FILE.FILE_SELECTION_DIALOG_INT will not work.
Java console shows following -
java.lang.ClassNotFoundException: oracle.forms.webutil.clientInfo.GetClientInfo
Caused by: java.io.IOException: open HTTP connection failed:http://abhamare-2k.cybage.com:7778/forms/java/oracle/forms/webutil/clientInfo/GetClientInfo.class

and so on..
Some how my java console too has stopped showing up after mistakingly clicked Hide Console.
So can any one help me to get out of this error.
Its sort of driving me crazy.
Thanks in advance.
Av.Hi Av, Can you let me know what you did to fix this issue? We are facing a serious issue with the same error and we can't get around it.
Thanks

WebUtil 1.0.6 - GetClientInfo bean not found.
I'm using Developer 10g Version 10.1.2.0.2 and the latest available Webutil-package 1.0.6.
I installed all components and followed all the steps.
When I execute the form test of webutil: WU_TEST_106 open a window with:
oracle.forms.webutil.clientinfo.GetClientInfo bean not found.
WEBUTIL_CLIENTINFO.GET_JAVA_VERSION will not work.
I did all the recommendations of metalink, but nothing.
Please, I need your help.By Edit - Preferences
?config=webutil , I did that, but the problem continue.

# $Id: formsweb.cfg 15-apr-2005.13:17:30 pkuhn Exp $
# formsweb.cfg defines parameter values used by the FormsServlet (frmservlet)
# This section defines the Default settings. Any of them may be overridden in the
# following Named Configuration sections. If they are not overridden, then the
# values here will be used.
# The default settings comprise two types of parameters: System parameters,
# which cannot be overridden in the URL, and User Parameters, which can.
# Parameters which are not marked as System parameters are User parameters.
# SYSTEM PARAMETERS
# These have fixed names and give information required by the Forms
# Servlet in order to function. They cannot be specified in the URL query
# string. But they can be overridden in a named configuration (see below).
# Some parameters specify file names: if the full path is not given,
# they are assumed to be in the same directory as this file. If a path
# is given, then it should be a physical path, not a URL.
# USER PARAMETERS
# These match variables (e.g. %form%) in the baseHTML file. Their values
# may be overridden by specifying them in the URL query string

# webutil.cfg - WebUtil default configuration file
# This file provides all of the configuration settings for webutil. These are
# divided into the following sections:
# 1. Logging Options
# 2. Installation Options
# 3. FileUpload and Download Options
# 1. Server Side Logging Options for logging errors and log messages
# You must set logging.enabled to true to allow mid-tier logging. Without this
# mid-tier logging will not take place no matter what PL/SQL or URL options
# are supplied to switch it on. Once logging is enabled the other settings come
# into play.
# Details
# logging.file : Defines the file name and location of the log file.
# Note that WebUtil does no log file management. You may
# need to manually clean this file up from time to time.
# logging.enabled : Can be TRUE or FALSE
# logging.errorsonly : Can be TRUE or FALSE. Setting to true will ensure that
# only errors and not normal informational log messages
# are written to the log file. For product use this would
# normally be set to TRUE
# logging.connections: Can be TRUE or FALSE. Setting to true will cause each
# connection from a client using WebUtil to write into
# the log as it sets up.
logging.file=
logging.enabled=FALSE
logging.errorsonly=FALSE
logging.connections=FALSE
# 2. Installation Options
# WebUtil needs to download some files to the client in order to perform
# certain integration operations such as OLE or Registry Access. These files
# are downloaded the first time that you access one of the functions that need
# them. You have to define the location of these files on the server
# Details
# install syslib.location : The virtual path to the directory holding the
# webutil library files on the server side. This
# must either be an absolute URL or a URL that is
# relative to the documentbase
# install.syslib.<os>.<package>.<n> :
# The name(s) of the libraries required for
# particular webutil beans. The format of this is
# name|size|version|showDownloadDialog. Multiple
# libraries can be downloaded per package. But
# ensure that the <n> values are consecutive and
# start at 1
install.syslib.location=/webutil
# Change size and version if necessary, like when upgrading the library.
# Normally this would not be required since most of these libraries come with
# install itself.
install.syslib.0.7.1=jacob.dll|94208|1.2|true
install.syslib.0.9.1=JNIsharedstubs.dll|65582|1.0|true
install.syslib.0.9.2=d2kwut60.dll|192512|1.0|true
# You can also add your own libraries in here, e.g.
#install.syslib.0.user.1=testwebutil.dll|204872|1.0|true
install.syslib.0.user.1=ffisamp.dll|40960|1.0|true
# 3. Upload / Download options
# For the file upload and download options you can define the default locations
# on the server that webutil can use as a work area. Optionally you can switch
# upload and download off
# Details
# transfer.database.enabled : Can be TRUE or FALSE - allows you to disable
# upload and download from the database server.
# transfer.appsrv.enabled : Can be TRUE or FALSE - allows you to disable
# upload and download from the application
# server.
# transfer.appsrv.workAreaRoot: The root of the location in which WebUtil can
# store temporary files uploaded from the client.
# If no location is specified, Application Server
# user_home/temp will be assumed.
# This location is always readable and writable
# no matter what the settings in
# transfer.appsrv.* are. This setting is
# required if you need the Client side
# READ/WRITE_IMAGE_FILE procedures.
# transfer.appsrv.accessControl:Can be TRUE or FALSE - allows you to indicate
# that uploads and downloads can only occur from
# the directories named in the
# transfer.appsrv.read.n and
# transfer.appsrv.write.n entries and their
# subdirectories. If this setting is FALSE,
# transfers can happen anywhere.
# transfer.appsrv.read.<n>: List of directory names that downloads can read
# from.
# transfer.appsrv.write.<n>: List of directory names that uploads can write
# to.
#NOTE: By default the file transfer is disabled as a security measure
transfer.database.enabled=FALSE

# $Id: default.env 14-apr-2005.13:22:43 pkuhn Exp $
# default.env - default Forms environment file, Windows version
# This file is used to set the Forms runtime environment parameters.
# If a parameter is not defined here, the value in the Windows registry
# will be used. If no value is found in the registry, the value used will
# be that defined in the environment in which the servlet engine (OC4J
# or JServ) was started.

Please, i can your help -
SOS : Bean not found in 'findByName'
Blank
Hi Rob,
thankx for the fast reply and the detailed explanations.
it's gettings things cleared for me..
let me explain the way I have understood your explanation.
I have an EJB (entity bean) called T_Exception. Suppose, this uses few classes in the jar file frwUtil.jar
So, do you mean to say that I should have a manifest file with the EJB Jar of T_Exception saying "Class-Path: frwUtil.jar" ?
And this frwUtil.jar should be a part of the .ear where I have T_Exception?
I have another EJB (session bean) T_ASM which uses T_Exception and also the classes in frwUtil.jar
So, do you mean to say that I should have a manifest file with the EJB Jar of T_ASM saying something like
"Class-Path: T_Exception.jar frwUtil.jar" or it just have to be "Class-Path: T_Exception.jar" ?
And this T_Exception.jar or frwUtil.jar doesn't have to be a part of this .ear file it the previous .ear file is already deployed, right?
Please correct me if am wrong.
In short, you are telling me that a support class or jar file which is deployed as part of an .ear file into an application server will be available for another EJB / class file in another .ear file which is also deployed after that. Am I right? I am getting confused in these areas.
Another doubt is about the significance of manifest files.
Is it something like one manifest file per a package / folder or something?
Can I have more than one manifest file for the same package? doesn't sounds logical but just to know
where and all manifest file comes into play? am not sure abt this..
Is there some good tutorial available to learn more about this? if yes, please let me know!
Like you said, setting the $CLASSPATH is definitely a bad practice. We are going to aviod that once this starts working. Thanks for your suggestion.
regarding dOubt 3 -
For your reference, below is the erorr that I got -
javax.ejb.ObjectNotFoundException: Bean not found in 'findByName'.
at com.tech.framework.propertyEJB.PropertyEJB_kzue3c__WebLogic_CMP_RDBMS.ejbFindByName(PropertyEJB_kzue3c__WebLogic_CMP_RDBMS.java:2001)
at java.lang.reflect.Method.invoke(Native Method)
the deployment of the bean goes without an error.
and it doesn't look like a Finder exception also, right?
and that's where am confused.
the same bean is working without any problems like this in 2 - 3 application server instances.
For the same reason, I don't think that there's a prob with the EJB QL used.
But now we are trying to remotely deploy the EJBs and deployment doesnt give an error too.
But the very first call to this bean is giving this error only in this set up.
and we are struggling with this since the past few days.. trying out all possibilities..
no luck so far.. .:(
Thankx again.. in advance..

dOubt No 2:
can I put all the support classes / jar files into the server the way I
deploy a bean?Yes, make a Jar (or jars) that have the support classes. Package them within
the EAR file and include a Class-Path entry in the manifest of any component
that uses these classes.
Here's an example: http://learnweblogic.com/updates/webauction.zip
Do not put the classes in the $CLASSPATH. You will not be able to redeploy
them if they are there.
mean to ask, can I make a .war or .ear file with all these support jar files
and ca I uplaod to the application server so that when I deploy a bean, it
will have these necessary dependency classes ready in the server? As of now,
I set the classpath in the startweblogic.cmd file which requires a server
restart every now and then I add something to the server classpath.
dOubt No 3:
when do I get Bean not found in 'findByName'?
I am rather confused with this error!
We'd need some more info here. Are you sure that your EJB-QL is correct?

[att1.html]
[Blank Bkgrd.gif]BlankIs it possible that a corresponding object is not found for this findByName call and hence it throws this?
because we tried accessing the same bean from an ordinary java client and it works!!!
but I thought if it's not finding an Object to return for a given key, it throws FinderException!
am more confused now, I guess..

Hi Rob,
thankx for the fast reply and the detailed explanations.
it's gettings things cleared for me..
let me explain the way I have understood your explanation.
I have an EJB (entity bean) called T_Exception. Suppose, this uses few classes in the jar file frwUtil.jar
So, do you mean to say that I should have a manifest file with the EJB Jar of T_Exception saying "Class-Path: frwUtil.jar" ?
And this frwUtil.jar should be a part of the .ear where I have T_Exception?
I have another EJB (session bean) T_ASM which uses T_Exception and also the classes in frwUtil.jar
So, do you mean to say that I should have a manifest file with the EJB Jar of T_ASM saying something like
"Class-Path: T_Exception.jar frwUtil.jar" or it just have to be "Class-Path: T_Exception.jar" ?
And this T_Exception.jar or frwUtil.jar doesn't have to be a part of this .ear file it the previous .ear file is already deployed, right?
Please correct me if am wrong.
In short, you are telling me that a support class or jar file which is deployed as part of an .ear file into an application server will be available for another EJB / class file in another .ear file which is also deployed after that. Am I right? I am getting confused in these areas.
Another doubt is about the significance of manifest files.
Is it something like one manifest file per a package / folder or something?
Can I have more than one manifest file for the same package? doesn't sounds logical but just to know
where and all manifest file comes into play? am not sure abt this..
Is there some good tutorial available to learn more about this? if yes, please let me know!

I have a login bean that verify's the user and on successful login, sets the bean in a session variable. Each page will then access the bean to verify the user. When there is no activity in the browser, the session expires, and the user has to log in again. I am getting the following error in my logs (java.lang.InstantiationException: bean not found within scope).
Is this ok? or would this be a memory leak?
ThanksAs long as the error is in the block that checks for the session then there is no problem as long you're catching the exception. Maybe its the way you check for the session that causes the error. Either way you shouldn't need to worry about it. The only problem would be if you were trying to set any variables/objects inside the block which you relied upon later in the page.

Disabling lazy loading will fix this, but results in unacceptable performance (load times go from 200ms to 22s). I'm not sure how else to handle this.
I am new to REST in ColdFusion, and it seems to me that the CFC's are being handled in an unusual way. They do not appear to be initialized (init method does not seem to run) and now it seems that ORM is not handled the same either. Am I missing something?
Here is the excerpt of my code producing this error:
component rest="true" restpath="item"
import model.beans.*;
remote item function getitem( numeric id restargsource="Path" ) restpath="{id}" httpmethod="GET"
var item = entityLoad("item",{ id = id },true);
return item;
And the bean:
component persistent="true" table="item" output="false" extends="timestampedBean" batchsize="10" cacheuse="read-only"
/* properties */
property name="id" column="id" type="numeric" ormtype="int" fieldtype="id" generator="identity";
property name="title" column="title" type="string" ormtype="string";
property name="description" column="description" type="string" ormtype="string";

I also noticed in the stdout log that Hibernate is logging the query, but then it logs the "No session" error:

Firefox will not open my previous session
Firefox 4 will not open any previous session once I shut down. I can have say 5 tabs open, close firefox, and reopen it and the session was saved. If I have those same 5 tabs open and shut down, then turn on my computer the next day, I can click on firefox, it will highlight the icon, and the highlight will disappear after about 5 seconds, and then I have to click it again, and it will open a totally new session. How do I fix this?
Make sure that you do not use [[Clear Recent History]] to clear the "Browsing History" if Firefox is closed.

Hi All,
I get the below error when i load my xsjs file in browser,
Error while executing query: [dberror(PreparedStatement.executeQuery): 2048 - column store error: column store error: [2950] user is not authorized : at ptime/session/dist/RemoteQueryExecution.cc:1354]
I am able to execute the same query in HANA SQL editor
Please note that ,No Analytical privileges are applied to the view.
Could you please help solving this issue.
Regards,
Logesh Kumar.Hay,
are you using the same Database user for both SQL Editor and XSJS ?
try the following.
Before executing the query , display it and copy the same from browser and execute in SQL editor.
Put the statement in a try catch block and analyse the exception .

I am using a Canon 640 printer and my MPNavigator will not remain open. It pops open then quickly closes. I've used it for several years but it just started doing this. What can I do to fix this problem?
I had a similar problem with a Canon MP800R under Mac OS X 10.9.2 Mavericks.
In my case, the MP Navigator app in the dock was linking to the wrong file.
It linked to Applications > MP Navigator 2.1.app > Contents > Resources > MP Navigator.app, but it should link to the "main" app, probably under Applications > MP Navigator 2.1.app.
After pulling the correct MP Navigator app file to the dock, I can start MP Navigator again by clicking on it in the dock. However, when clicking on it, a second MP Navigator icon will show up in the dock and stay there until the app is closed. By the way, the MP800R scanner also works (although officially not supported by Canon).
