FILE.IO.PERMISSION and SOCKET.PERMISSION when calling jdev proxy from DB

Hello everybody,
i deployed a webservide proxy (made in jdev 10.1.3.2) to an oracle 10gR2 database. Invoking this proxy works very well when calling it (as a procedure in the database) on the same machine as the DB is running.
But when trying to invoke the procedure remote on the DB-server from another pc i get 2 error messages (randomly):
java.security.AccessControlException: the Permission (java.net.SocketPermission 192.168.20.1:1521 connect,resolve) has not been granted to VECOZO. The PL/SQL to grant this is dbms_java.grant_permission( 'VECOZO', 'SYS:java.net.SocketPermission', '192.168.20.1:1521', 'connect,resolve' )
java.security.AccessControlException: the Permission (java.io.FilePermission \\WEBFS01\WEBFS01_Vecozo\Temp\Acc\MAY07 read) has not been granted to VECOZO. The PL/SQL to grant this is dbms_java.grant_permission( 'VECOZO', 'SYS:java.io.FilePermission', '\\WEBFS01\WEBFS01_Vecozo\Temp\Acc\MAY07', 'read' )
I gave this permissions in the sys schema to the vecozo schema following the example the error produces for me, but it doesnt work! When i grant socketpermissions on the port secified by the error and i run the proxy again the db comes up with the same error, only with a different port number. I'm getting crazy here. Also the granting of the file.io permission seems to have no result.
What is strange is that it all works when invoking the proxy locally (from the pc as where the db is running). I think this is because locally you dont need socketpermissions (as sockets are primarily for communication with other pc's). Furthermore i did not even grant the file permission when working locally in my testenvironmentand it all worked just fine. so i dont know why i suddenly need this permission when invoking the procedure on the productionserver from an external pc.
Can somebody plz help me with this????
greetz,
Kim

Anybody :)

CallerPrincipal when calling one sessionbean from another

Hi all,
I have a little problem when calling one sessionbean from another sessionbean. The problem is, that in the method, which is called, is used SessionContext's getCallerPrincipal().getName(). This works great from client, but from other sessionbeans getCallerPrincipal() retuns an "ANONYMOUS" principal. How can I set the correct principal (the principal from the first sessionbean)?
Thank you
My env: Glassfish 2.1.1, Netbeans 6.8, Eclipselink 2.0.0, Java 1.6.0.18
My code:
@Stateless
public class ABean implements ASessionRemote{
@Resource
SessionContext ctx;
@Override
public void aMethod(){
String name = ctx.getCallerPrincipal().getName(); // the name is ANONYMOUS, when the call is done from other sessionbean
@Stateless
public class BBean implements BSessionRemote{
@Resource
SessionContext ctx;
@EJB
private ASessionRemote aSessionBean;
@Override
public void bMethod(){
aSessionBean.aMethod();
}

"This works great from client"
What do you mean by this, i.e what sort of client are you using (stand alone app, servlet) ?
what shows up if you printout the caller principal in the calling bean ?
are the two ejbs in the same ear ?
what security meta-information are you using in ejb-jar.xml and sun-ejb-jar.xml, if any ?

[svn:fx-trunk] 13201: Fix RTE when calling PopUpManager.createPopUp() from a module or sub-application.

Revision: 13201
Revision: 13201

Log Message:
Fix RTE when calling PopUpManager.createPopUp() from a module or sub-application.
This fix adds a moduleFactory parameter to PopUpManager.createPopUp() to allow a module or sub-application to specify the style manager to be used. Modules and sub-applications should always pass a moduleFactory to PopUpManager.createPopUp() or PopUpManager.addPopUp() to ensure the correct style manager is used when looking up styles. Otherwise the parent of the pop up is used to determine the style manager.
QE notes: Please create a PerModuleStyles test that uses the new parameter to createPopUp().

Video only enabled when call is initiated from one direction across SIP Trunk

wonder If anyone can shed some light on this.
I have an issue between two cucm clusters, tied together with a SIP trunk.
If we dial from Australia to the US there is two way video and audio. If the US calls Australia, there is only audio. I have run a test call from the US through VLT and have found the following SDP's (see below). When The US make a video enabled call to australia the message "Video is not available, Remote party has video off" on the US phone screen.
Both clusters have the SIP trunk set up with the same codec settings and video bandwidth between reqions and locations. the SIP trunk is configured pretty much stock standard and identical at both ends, yet the SDP seem to want to negotiate different Video Parameters (again see SDP's below). CUCM in australia is 10.61.2.82.
what other settings can I check to get video to work when calls get initiated from either direction,...................
both phones are SIP 8941's, again audio is no problem in both directions.
=======this is from the phone in Australia to the CUCM in australia phone IP 10.61.4.112======================================

2. not that I know of
been looking for something a bit like it got an old ipod thouch in a audio dock in the kitchen and want to give it access to all my music not just play what is synced
so far my only options is to get an app to use upnp to get the music directly from my nas
or get some app which require the computer to be running and running some program to handle it
and as far as I can tell getting access to stuff synced on the atv is a no go

Sync Async using proxies ( Calling Outbound proxy from Inbound proxy )

I'm trying to generate Asynchronous Outbound message from the Synchronous Inbound message message due to a requirement. My question is : is it really possible to develop such a scenario?. I'm getting weird error such as Kernal exception etc. Please let me know if you have developed such scenario and what should we do dfifferently in such scenarios?. Thank you for any suggestions.

Hi,
This error has has nothing to do with Calling Outbound Proxy from from Inbound Proxy. The scenario which you are telling is very much possible.
It looks like there is some problem in your proxy code while calling RFC from within there or something like that. Try catching the exception and see what is the exact error or put in debug mode and see the step where exactly your code is failing.
Use the following links for Catching Exception in Proxy

Missing permission when calling sap transaction via composer

Hello,
we have created a complex model. in this model some sap transaction are called.
With Administrator rules everything is working fine.
but when portal role is assigned to a normal user, only real composer parts are working and all url ivew calling an sap transaction are failing.
where do I have to adjust permission ?
An exception occurred while processing a request for :
iView : N/A
Component Name : N/A
Access denied (Object(s): portal_content/com.sap.pct/templates/iviews/com.sap.portal.sap_transaction_iview).
Exception id: 11:20_14/02/08_0022_6998651
See the details for the exception ID in the log file
Thanks

Hi Uwe,
i guess you're calling the "pcd:portal_content/com.sap.portal.migrated/ep_5.0/templates/com.sap.portal.appintegrator.sap.bwc.TransactioniView" with some parameters (system, tcode, etc.). You have to add this iview to your models role (our change the permissions of the iview). To hide in the navigation, edit the iview preference: com.sap.portal.navigation.Invisible (German: Unsichtbar in Navigationsbereichen) -> change it only in the role->iview, do not change it in the iview itself.
Hope that helps!

Permission Denied Error when calling Matlab script from LabWindows/CVI

Hello,
I am reading in data from a DAQ and am writing it to a .csv file in LabWindows/CVI. I am then sending this data to Matlab to be filtered. I would like the filtered data to be accessed by LabWindows/CVI so that I can display it as a strip chart. I have gotten everything to work except the writing to a file in a Matlab script that is called from LabWindows/CVI. I am basically using the shipped example in found in the activex demo. (http://zone.ni.com/devzone/cda/epd/p/id/2994). I select the script that I want to run and each time it tries to open a file with write permissions I get a "Permission Denied" error. This occurs when using fopen() in Matlab. I have also tried using csvwrite() as well as dlmwrite(). Each one gives me a similar error. The script currently does not try to do any data processing. It just opens the file, if it is successful it then prints "hello" and then closes it. The script works well when it is run in Matlab, just not when it is called in LabWindows/CVI. Below is the script. Any thoughts, comments or suggestions are greatly appreciated. I am also open to using other approaches for sending data between Matlab and LabWindows/CVI. Thanks in advance!!
fclose('all');
[file, errmsg] = fopen('out.txt', 'w');
if(file<0)
   disp(errmsg)
else
   fprintf(file, 'hello');
   fclose('all');
end;
[file, errmsg] = fopen('out.txt', 'w');
if(file<0)
disp(errmsg)
else
fprintf(file, 'hello');
fclose('all');
end;

I am using Windows 7. I am running CVI as an administrator and was able to get rid of the "Permission Denied" error by going into the User Account Controls in windows and changing it to "Never Notify". However, this did not fix the problem of Matlab not being able to write to a file when the script is run from CVI. In the Matlab code below, It now gets in to the "else", suggesting that fopen() returns a good file handle. After getting in to the else statement, it will not actually write to the file, nor does it create it. However, I can make changes to the plot settings and those appear. Everything is functional when run from Matlab but when run from CVI, things get screwy with opening the file for writing. It handles the read well. It seems like there would have to be some file permission errors but, in the CVI program, I open and write to the file "in.csv". Any help is greatly appreciated.
clear;
fclose('all');
t = zeros(1000);
t = csvread('in.csv');
for i=1:1000
   t(i) = t(i)*4;
end;
[file, errmsg] = fopen('out.txt', 'w');
if(file<0)
   disp(errmsg)
else
   fprintf(file, 'goodbye');
   for i=1:1000
   %t(i) = t(i)*3;
   fprintf(file, '%f,', t(i));
   end;
   fclose(file);
   plot(t/3, t);
   ylabel('t');
   xlabel('Time (s)');
   title('Is this really working?!?');
end;
Thanks,
Chris

Permission Denied when calling a method from VB using WebLogic 8.1.2 JCOM

Hi,
We are calling an java/ejb methods from VB using WebLogic JCOM 8.1 SP2. But
using JCOM, we are getting a error Permission denied when called from VB. We think
that we should update pathch jintegra 2.0 or 2.1 in WebLogic 8.1.2 the to solve
this issue, because we faced the same problen "permission denied" when we used
JINTEGRA(third party software). Once we installed the JINTEGRA 2.1 it solved the
issue.
So, can anyone help on regard to this issue of "Permission denied" in WebLogic
JCOM 8.1 SP2.
Thanks & Regards
Raghu

I too am experiencing the jCOM error: "Run-time error '70': Permission Denied". The problem appears to be related to a Microsoft Security Patch KB835732 (MS04-011 which, as you indicated, has been fixed in J-Integra v2.1 (FYI, jCOM 8.1 is based on J-Integra 1.5.4, see J-Integra/jCOM versions.
Did you ever get a resolution concerning 8.1 SP2? 8.1 SP3 is available now but I don't see any mention of jCOM updates in the WebLogic 8.1 What's New documention. I can't immediately upgrade (trying to stay on same version as a few other developers I work with) but I am hoping it is resolved in SP3.

Hide UserID, Password, and Report Path when call Report from Report

Hi,
I have been able to call Report from Report using the hyperlink.
I put these code in my Field on the Report caller.
function F_3FormatTrigger return boolean is
temp varchar2(2000);
begin
temp := 'http://<computer_name>:8889/reports/rwservlet?';
temp := temp || 'server=repsrv' || '&' ||
                     'report=C:\MyReport\rep_detail.jsp' || '&' ||
                     'userid=scott/tiger@orcl' || '&' ||
                     'desformat=htmlcss' || '&' ||
                     'destype=cache' || '&' ||
                     'P_1=' || :ItemID || '&' ||
                     'P_2=' || :ItemName;
SRW.Set_Hyperlink(temp);
return (TRUE);
end;The hyperlink showed, and I can see the rep_detail.jsp showed in the same browser after I clicked the hyperlink.
The problem is, the hyperlink has to include the reports path and also userid and password.
If I did not put the userid and password, it will showed in another browse that
"The report has uncompiled PL/SQL"
How can I hide those userid, password, and the reports path?
BTW, Is there anyway to show the report callee in different page (precisely, open another IE) from the report caller?
Any help would be grateful.
Many thanks,
Buntoro

Hi,
Thanks for the answers.
Yet, I am still doubt about using cgicmd.dat.
I have looked around in this forum saying that it is not secure to use cgicmd.dat. Because all report request does not use authentication (the client can directly open report without login).
In Form, I can use the On-Logon to do the Oracle Form login (to do logon to the database), and then I use my own custom user login to restrict the menu for each user.
I do this since I want to restrict the user,
i.e user A can only view the sales form as well as sales report,
user B can only view the purchasing form as well as purchasing report.
Well, I am not so fond about the SSO itself.
It comes to my mind, since I don't have to re-login (to the database) each time I call another form (login database is only once at the first Form, On-Logon). It also goes to when calling the report caller.
What is RAD?
How can we use it?
Is OID = Oracle Internet Directory?
If true, maybe, I won't use it since I don't understand about it also.
Why we don't have to specify the userid and password when Form calls Report1 (using Run_Report_Object and Web.Show_Document())?
But we have to specify the userid and password when Report1 calls Report2.
Any help is appreciated.
Many thanks,

About 1 week ago deleted email's have shown up in my inbox. I have gone into my deleted file and deleted them all forever. I am still receiving old email's in my inbox and of course when I dlete them from the inbox more go into the trash file.e

This was thourough. Trash emails going into my in box. when I delete them more come into the inbox. I deleted all the emails in the trash file. When I delete them from the inbox they go back to the trash and back & forth we go.

Sorry, not a Firefox support issue as Firefox doesn't do email, it's a web browser.
If you are using Firefox to access your mail, you are using "web-mail". You need to seek support from your service provider or a forum for that service.

Error when calling a procedure from my apex application

Hello.
I want to create a small APEX application that can configure asynchronous change data capture (distributed hotlog) on certain tables.
Basically, what the application should do is to simply create change tables. Everything else is set up as prerequisite.
My problem is that when I run the following script from schema apex_cdd (using sqldeveloper) , it works; but if I run it from my apex application by calling it when pressing a button as a pl/sql process, it doen't work.
BEGIN
apex_cdc.enable_table_capture
     (     i_owner => 'staging_cdcpub',
          i_change_table_name     => 'g_changeTable',
          i_change_set_name     => 'Source_changeSet',
          i_change_source          => 'orcl01_cs',
          i_source_schema          => 'My_src',
          i_source_table          => 'G',
          i_column_type_list     => 'STARTDATE DATE,STATUS CHAR(1),NAME VARCHAR2(10),ENDDATE DATE,DESCRIPTION VARCHAR2(255),ID NUMBER(8,0),VALUE NUMBER(10,2)'
END;
If I look in the trace file, i see that the error is:
CDCdebug:in ChangeTable.java enableDisabledTriggers: ORA-06550: line 1, column 8:
PLS-00201: identifier 'SYS.DBMS_CDC_SYS_IPUBLISH' must be declared
ORA-06550: line 1, column 8:
PL/SQL: Statement ignored
oracle.jdbc.driver.OracleSQLException: ORA-06550: line 1, column 8:
PLS-00201: identifier 'SYS.DBMS_CDC_SYS_IPUBLISH' must be declared
ORA-06550: line 1, column 8:
PL/SQL: Statement ignored
Other remarks:
- My procedure calls: sys.DBMS_CDC_PUBLISH.CREATE_CHANGE_TABLE.
- I gave the same rights that I gave for apex_cdc schema to flows_030200 and APEX_PUBLIC_USER schemas (just to see if it works), but it doens't.
Is APEX calling the procedure from another schema ?
Does anyone has an idea why this procedure crashes if called from APEX application, but works ok if called from the same schema APEX application runs on, but using SQLDeveloper ?
Any thoughts are appreciated.

The procedure apex_cdc.enable_table_capture i created myself with no authid mentioned explicitly, so it uses definer rights, by default.
BUt this procedure is simply a wrapper for sys.dbms_cdc_publish.create_change_table.
When I look on the security model for this sys.dbms_cdc_publish, i see it runs under invoker rights. (http://www.psoug.org/reference/dbms_cdc_publish.html).
The code is like this:
CREATE OR REPLACE PROCEDURE enable_table_capture
          i_owner               IN VARCHAR2,
          i_change_table_name     IN VARCHAR2,
          i_change_set_name     IN VARCHAR2,
          i_change_source          IN VARCHAR2,
          i_source_schema          IN VARCHAR2,
          i_source_table          IN VARCHAR2,
          i_column_type_list     IN VARCHAR2
     IS
     BEGIN
          EXECUTE IMMEDIATE 'alter session set REMOTE_DEPENDENCIES_MODE=SIGNATURE';
          EXECUTE IMMEDIATE 'begin add_log@orcl01(i_tableName => ''G''); end;';
sys.DBMS_CDC_PUBLISH.CREATE_CHANGE_TABLE(
owner => i_owner,
change_table_name => i_change_table_name,
change_set_name => i_change_set_name,
source_schema => i_source_schema,
source_table => i_source_table,
column_type_list => i_column_type_list,
capture_values => 'both',
rs_id => 'y',
row_id => 'n',
user_id => 'n',
timestamp => 'y',
object_id => 'n',
source_colmap => 'n',
target_colmap => 'y',
options_string => NULL);
END enable_table_capture;

Java.lang.ClassCastException when calling webservice stub from oracle DB

Hello everyone,
Because i need to get familliar with calling java webservices from an oracle database, i followed the following example
(http://www.oracle.com/technology/products/jdev/howtos/10g/WS_DBCallout/DBCalloutWS_HowTo.htm),
which included installing the SOAP client stack to the database (in the sys schema), grant the right permissions to the SYS user, developing a simple Helloworld webservice with jdeveloper 10.1.2, generating a Webservice stub and deploying a static method of this stub to the database.
All of this worked just fine, but when i want to call the webservice from oracle by invoking the deployed function, i get a java.lang.ClassCastException.
The complete stacktrace lists as follows:
v_Return = foutje: java.lang.ClassCastExceptionnulljava.lang.ClassCastException
     at org.apache.soap.rpc.RPCMessage.serializeParams(RPCMessage.java:323)
     at org.apache.soap.rpc.RPCMessage.marshall(RPCMessage.java:305)
     at org.apache.soap.Body.marshall(Body.java:148)
     at org.apache.soap.Envelope.marshall(Envelope.java:203)
     at org.apache.soap.Envelope.marshall(Envelope.java:161)
     at oracle.soap.transport.http.OracleSOAPHTTPConnection.send(OracleSOAPHTTPConnection.java:664)
     at org.apache.soap.rpc.Call.invoke(Call.java:261)
     at test.HelloWorldServiceStub.sayHello(HelloWorldServiceStub.java:82)
I debugged the WebServiceStub and noticed that the call.invoke method crashes. This is weird beacuse when i use System.out.println on the parameter is works just fine. so you would think it is a string.
Moreover, if i invoke the webservice from the endpoint or even when im debugging the stub locally it all works just fine.
Can someone plzzzzzz help me with this because i spend the whole day looking for an answer and im getting crazy!!!!!
Thanx al lot guys,
Kim
PS or could the problem be in the database instead of the webservice?????????

I think that it's going wrong because i did not install the right SOAP client stack.
In the HowTo is specified what JAR files are to be loaded in the database (from %JDEV_HOME), but it states that it has only been tested on a Oracle 9.2 database. I'm using Oracle10g. Maybe that's the reason that im getting this classcast exception...
Can anybody tell me what the right .JAR files are that have to be loaded into database when working with Oracle 10g?
Many thx in advance!
