Hi Everyone,
Please I need Help I try to load Log4J en Database 10G, When I try to compile the class in toad, or in database, sende a message error the class are:

I dont now what to do, if enyone know what cause this error, I try to update the JDK in data base to 1.5 but I dontknow to do.

Alcides,
For your information, the Oracle 10g database embedded JVM is compatible with java 1.4 and so supports logging. Hence no real need to install Log4j.
As far as I know, you cannot upgrade the Oracle database embedded JVM.
(See your How Install JDK 1.5 in Data Base Oracle 10G, urgent pleeeeese.)
Certainly looks like the version of Log4j you are trying to use is compatible with java 1.5, so if you insist on using Log4j, you'll have to use a version that is compatible with java 1.4. Sorry :-(
By the way, I think the Java in the Oracle Database forum is the most appropriate for your question.
Good Luck,
Avi.

Getting error with Log4j

Hi,
Not sure if this is the right place to post this as it is a problem with log4j really and not java. Let me know if this needs moving.
Here goes:
I have a servlet in tomcat that uses log4j to log details, this works fine on all the systems at home and work, but I get the following error when it is run on our customers site:
log4j: No appenders could be found for category (some.category.name).
log4j: Please initialize the log4j system properly.
I have looked this up on log4j's website, they give the following advice:
Log4j does not have a default logging target. It is the user's responsibility to ensure that all categories can inherit an appender. This can be easily achieved by attaching an appender to the root category.
This works fine off site? I have the following log4j.properties in the WEB-INF/classes dir in tomcat:
log4j.rootCategory=DEBUG, dest1
log4j.appender.dest1=org.apache.log4j.FileAppender
log4j.appender.dest1.file=/rmx.log
log4j.appender.dest1.layout=org.apache.log4j.PatternLayout
log4j.appender.dest1.layout.ConversionPattern=%-5p %l %x: %m%nAny ideas?
Thanks in advance.
Phil Maskell

I have added code similar to what you suggested,
being deployed on Tomcat I get the following:
java.class.path=C:\Program Files\Apache Group\Tomcat
5.5\bin\bootstrap.jar
Is this what I should get? This is on my working
system.That was probably not a good test (in hindsight). Tomcat's classpath is evidently not where its servlet classloader looks for classes.
My log4j code uses a logFactory, in a final class,
will this have any effect on the class path?The fact that the class is final will have no effect on any classloading. I doubt whether a logfactory will either, but I don't know what that is.
P.S I could post my Logger.java, but stupid thing is
it works fine on all my systems, just not on the
customers :(I put my log4j.properties in the web app's WEB-INF/classes directory, just like you did. If your customer's system is not working the same as yours then you are probably wasting your time looking at Java code. The two systems are not configured the same and you need to find the difference.

File not found error with log4j.properties

Hi,
I'm writing a web service on weblogic 8.1 with weblogic workshop.I have to use log4j-1.2.7 supplied by client with my application.I cannot write ant script manually.Also I cannot change server start script or cannot put any command line argument when the server starts.
Now I require this logger in my EJB.I have kept log4j.properties in the same path where my EJB's are.But the final ear produced does not contain this log4j.properties and subsequently I get the error "log4j:ERROR Could not read configuration file [log4j.properties]."
Please help me to resolve this problem so that log4j.properties goes with the final .ear file and the ejb code finds the logger.
thanks,
pratim

Hello,

Error with import of new compiled java package

Hi,
in order to change some code in the java classes of the packages stored in the VV2-Content, 1.0 of SAP -> http://sap.com/xi/ISU-IDEX-GE/VV2 -> Mapping Objects -> Imported Archive, I exported all packages in this folder, extracted them, decompiled some classes (using jad), in which I would like to change some code, and imported these classes associated with other exported packages in a new project of eclipse. after changing the code and successfully compiling these java classes (with no error), I exported the ".class" from eclipse, replaced the old ".class" in the packages with the newly compiled ones(in a zip file) and at the end imported the changed packages (in zip files) in the folder "Imported Archive". After saving and activating the change, I sent an IDOC from R3 system to the XI system for test. In the monitor of the XI system, there was an error, which is
"Inkompatible Versionen von Klassen (Linkage Error)" (in English "incompatible versions of classes (linkage error)"). Can anyone tell me, how I can do with this error? Thanks.

Vishal,
thanks for your reply. Actually I did change some code in the decompilied class "XEdixml2EdiConverter". I think this class does nothing with mapping(transformation), but it converts the tranformed edixml to final edifact. Can I test it in the repository as you said?

Error with SQL Loader 10g

Hi,
I use SQL Loader to load files into my database running on Suse Linux. The loader is invoked by a Java application.
In Oracle 9i my string would be something like
sqlldr DATA='opt/test information/sample.dat' PARFILE=/opt/test.par
It worked.
When I ran the same string in 10g I got an error like
" multiple values not allowed for parameter 'data' "
I tried escaping the ' with a \ , like
sqlldr DATA=\'opt/test information/sample.dat\' PARFILE=/opt/test.par
Now it gives me a different error
SQL*Loader-500: Unable to open file (opt/test information/302.DAT)
SQL*Loader-553: file not found
I cannot remove the space from the directory. It has to be "test information".
Can anybody help me out?
Thanks,
Karthik

or better yet, you are on Linux so you have the luxury of creating a symbolic link to that directory and make the sym link without spaces and then use that in your sqlldr command line.
you can keep the directory with spaces and have sqlldr run from the sym link.

Loadjava ORA-29521 errors with log4j

Hi,
I've got ORA-29521 errors while loading a Java JAR library. The Java application is using log4j for logging messages.
The loadjava output is :
creating : resource log4j-1.2.8.jar
loading : resource log4j-1.2.8.jar
errors : class com/blabla/transferservice/TransferService
ORA-29521: impossible de trouver le nom rÃ©fÃ©rencÃ© org/apache/log4j/Logger
ORA-29521: impossible de trouver le nom rÃ©fÃ©rencÃ© org/apache/log4j/xml/DOMConfigurator
I also tried to include in the JAR the following libraries without resolving the problem :
mail-1.2.jar, activation-1.0.1.jar, xercesImpl-2.4.0.jar and xerces-2.4.0.jar.
Someone could tell me what's going wrong ?
Thanks.

UV,
I believe the problem is due to the fact that you are using the "-resolve" option in your "loadjava" command.
Oracle will eventually "resolve" all loaded classes -- so you don't have to ask it to resolve your classes while they are being loaded. Hence you should be able to issue your "loadjava" command without the "-resolve" option.
Alternatively, (if you need/want to retain the "-resolve" option) you can also supply the "-genmissing" option -- which is designed to overcome the "resolve" problems you are experiencing.
For your information, "loadjava" is documented in the "Oracle 9i Java Developer's Guide" which is available from:
http://tahiti.oracle.com
Good Luck,
Avi.

Spring framework - Error with session scoped Beans

Hello guys,
I'm trying execute my Java Application inside Netweaver Application Server, but I'm having problems with serviceBeans with scope session. Anyone have already used Spring with session scope?
Thanks,
Cleiton.

After many attempt, when I declared the bean with <aop:scoped-proxy /> it works, however it could cause performance problem. I don't need refer this bean by another singleton bean, i did a wrong configuration in order to make a work a round...
When I run my application on tomcat server, the DWR starts perfectly the "session scope bean form IOC container", but in the WEBAS maybe it's running in other thread. Is it possible?
Anyone had a problem like this?
I got a detailed error with log4j,

Hi All
on our dev server in an attempt to Compile APEX 3.1.2 with RHEL4 on 10G 10 SQL*Plus: Release 10.2.0.4.0 - Production on Fri Feb 27 10:13:59 2009
use Apache mod_pl version
I tried to follow from
link[joelkallman blog|http://joelkallman.blogspot.com/2009/02/make-all-of-your-apex-applications-run.html]
and did this:
column plsql_optimize_level format 999
column plsql_code_type format a20
select count(*), o.object_type, s.plsql_optimize_level, s.plsql_code_type
from dba_objects o, dba_plsql_object_settings s

exec dbms_utility.compile_schema('FLOWS_030100');
Caused errors "missing f" in urls like

I restarted oracle and apache and no change in error
ran the following in sqlplus and all recovered. :) happy about that!
alter session set plsql_optimize_level = 2;
alter session set plsql_code_type = interpreted;
exec dbms_utility.compile_schema('FLOWS_030100');
Is this possible on 10g? if so how?
Thanks
Frank

Thanks for your reply, Roel!
I always deeply thanks for your help.
After reading your reply, I found out I missed install HTTP Server.
So I have installed HTTP Server in companion CD and I made the adjustment like marvel.conf and httpd.conf.
But I can't solve my problem yet.
I entered the address - http://127.0.0.1:7777/pls/apex/apex_admin - in the web browser, then
I saw such a like under the message.

"catch is unreachable" compiler error with java try/catch statement

I'm receiving a compiler error, "catch is unreachable", with the following code. I'm calling a method, SendMail(), which can throw two possible exceptions. I thought that the catch statements executed in order, and the first one that is caught will execute? Is their a change with J2SE 1.5 compiler? I don't want to use a generic Exception, because I want to handle the specific exceptions. Any suggestions how to fix? Thanks
try {
SendMail(....);
} catch (MessagingException e1) {
logger.fine(e1.toString());
} catch (AddressException e2) {
logger.fine(e2.toString());
public String SendMail(....) throws AddressException,
MessagingException {....

I found the problem:
"A catch block handles exceptions that match its exception type (parameter) and exception types that are subclasses of its exception type (parameter). Only the first catch block that handles a particular exception type will execute, so the most specific exception type should come first. You may get a catch is unreachable syntax error if your catch blocks do not follow this order."
If I switch the order of the catch exceptions the compiler error goes away.
thanks

Compilation error with geolocation

I'm getting a strange error when packaging the IPA file with Flash CS5. Compilation fails because of "invalid input". This only occurs when I add the geolocation classes. Could it be that I am compiling against the wrong sdk? Where can I set this in the Flash ide?

Sure. I'm not doing anything special but the app occasionally crashes when the geolocation callback arrives.
public function ClassConstructor():void
if (Geolocation.isSupported)
geolo = new Geolocation();
geolo.addEventListener(StatusEvent.STATUS, onGeoStatus);
protected function onSomeEvent(event:Event):void
geolo.addEventListener(GeolocationEvent.UPDATE, onGeoUpdate);
protected function onGeoUpdate(event:GeolocationEvent):void
geolo.removeEventListener(GeolocationEvent.UPDATE, onGeoUpdate);
tf2.appendText("latitude:" + event.latitude.toString() + "\n");
tf2.appendText("longitude:" + event.longitude.toString() + "\n");

Compilation errors with JDeveloper 10.1.2.2.0

Hello,
I want to change my environment work. First I worked with Eclipse (Europa, jre 1.6), I have no error with my following code source :

and now I have a compilation error with the same code
' Error(43,14): <identifier> expected '
I think it's a compiler version problem but I'm not sure and I don't know how to change the compiler version.
If someone have any idea, I will be happy to receive response.
Thanks

Error unsupported memory access on variable 'Decoder.number_of_values' which is (or contain) an array with unknown size at compile time

Dear All,
I am a new user of Vivado HLS. I want to pass an array of struct to a function and use elements of struct multiple times in a function (read and write). I find this error "error unsupported memory access on variable 'Decoder.number_of_values' which is (or contain) an array with unknown size at compile time " . Kindly can anyone tell that is it an issue of directive? if yes then which directive to use for struct and its element. Struct and function are as follows.
typedef struct {
uint32_t number_of_values ;
uint32_t address[16];
uint8_t Processed_bit :1 ;
uint32_t links[6];
} Decoder_Fields;
void Raptor_LT_decode(int To_Send,Decoder_Fields *Decoder){
   int counter=0;
   int i=0,j=0,k=0,x,aaa;
   Raptor_LT_decode_label0:while(counter<To_Send){
       if((Decoder[counter].number_of_values ==1) &&(Decoder[counter].Processed_bit==0) ){
           Decoder[counter].Processed_bit=1;
           Raptor_LT_decode_label1:for (i=0; i<To_Send;i++){
               Raptor_LT_decode_label2:for (k=0;k<Decoder[i].number_of_values;k++){
                   if (( Decoder[counter].links[0]==Decoder[i].links[k]) && (counter != i)&&       (Decoder[i].number_of_values!= 1)) {
                       Raptor_LT_decode_label3:for (j=0;j<BLOCK_SIZE_BYTES/4;j++){
                               Decoder[i].address[i]= Decoder[i].address[j] ^ Decoder[counter].address[j];
                       for (x=k;x<Decoder[i].number_of_values-1;x++) Decoder[i].links[x]=Decoder[i].links[x+1];
                                  Decoder[i].number_of_values--;
           counter=0;
       else
           counter++;

Hi ,
This question is asked on the forum from time to time and should be described in the UG902
In your top level, Decoder is a pointer; this is not supported as-is as you need to know its size when you do something like Decoder[i].XXXX : the tool need to know how many bits to size the addess bus.
you need to change Decoder_Fields *Decoder to Decoder_Fields Decoder[YOURSIZE]
with YOURSIZE that makes sense; in this case the tool will know that it need N=log2(YOURSIZE) to fully address the Decoder array variable.
next when you solve that and that all is good... the question that you will need to transfer the data of the structs from host memory to your VHLS IP; you need to think about this.
I hope this helps.

Errors in Import on 10g r2...

I have got a Oracle 08.01.07 which I am importing to a 10g R2 database. I created a new database, then created all the tablespaces and setup tnsnames as per requirements of db links to be created (checked it with show=Y option). After running the import, its mostly successfull but there are some erros for which I dont seem to understand the reason. Posting here to know your thoughts that what could be the reason for the same.
1. ORA-01031: insufficient privileges error with creation of few DB links.
2. IMP-00041: Warning: object created with compilation warnings in "create force view"
3. ORA-01031: insufficient privileges with creation of few snapshots. My concern is that as its export of a production database, why its giving problems while creating in 10g. These privilege issues should not be there. Any ideas, please post.
Thanks
