Applet Database Proxy Problem

Hello all,
I have an applet which connects to a MySQL database for user authentication. Currently I am doing on a local machine and all goes well and fine. But my problem is the same applet when accessed through a proxy the database connection wont happen. Can someone suggest a way to solve it. Or this problem is not solvable.
Thank you
joseph

Use http to do the authentication. Have the applet make a request to the authentication server by name (not by codebase, as this is probably the source of the proxy problem). On the authentication server, you can run a servlet or cgi or whatever to contact the db.

Applet database access problems!

Hi,
I have a major problem. I'm trying to design an applet that can talk to a database server which is not the same server where the applet is hosted. I keep getting an exception like below: (note I changed my db server name)
java.sql.SQLException: Unable to connect to any hosts due to exception: java.security.AccessControlException: access denied (java.net.SocketPermission aaaa.bbbbb.net resolve)
at com.mysql.jdbc.Connection.createNewIO(Connection.
help?

Ok, I went back and re-read the answer to a similar question I asked earlier. Since I can't talk directly to the other db server, what is the work around?
Make a php page that updates the database, then call that page from within the applet?

In OEL5.7 this works fine without any problem. I think this related to OEL6.1, maybe YUM does not understand proxy, my password for proxy starting with @$ but I changed my password and

If it doesn't work, it's a proxy problem.Yes it works , interesting that user and password parameters not working with double quotes only with single.
I also checked this with YUM but YUM is having problem with passwords that starting
with "@" symbol. I try to set
export http_proxy="http://username:\@$passwd@IP:PORT"
for ignoring "@" symbol but no sucess. With OEL5 this is not a problem. In /etc.yum.conf same username and same password.
Perhaps I should change my password :)
and last one thing in my home network I have OEL6.1 ( where fortunately with no proxy :) ) I try update linux with "yum update" command
and it returns that no packages to update , can you tell me why because there are new kernel avalable and I can download and install this new kernel with command "yum install kernel".

Database termination Problem

Hi every body ..plz help me on this..
We are facing database termination problem in ECC6 production syste.
Database: Oracle 10.2, O/S: Windows 2003. Spam :27, SP level 13.
Error is:
Errors in file f:\oracle\p02\saptrace\background\p02_ckpt_6520.trc:

O/S-Error: (OS 33) The process cannot access the file because another process has locked a portion of the file.
When we are performing backup then data base termination occuring freequently.
Give right solution as early as possible.
Thanks,
Nani.

Hi,
Have a look at below snote which actually speaks about the oracle error codes
Snote : 546006
within the Snote it says :-
" If you cannot access a database file (for instance a data file, control file or RedoLog) for whatever reason, an ORA-270xx appears. The actual cause comes from additional error messages (usually in the operating system) that occur on ORA-270xx. "
And as per your last update
" ORA-00206: error in writing (block 3, # blocks 1) of control file
ORA-00202: control file: 'D:\ORACLE\P02\ORIGLOGB\CNTRL\CNTRLP02.DBF' "
i think there is problem accessing the database control file. Hence you are facing the above problem.
I think if you recreate your control file i think, it should resolve the problem.
Hope it will be helpful to resolve your problem.

XI ABAP Proxy problem

Hi all,
I am trying to develope an itegration scenario as follows:
ABAP System ---> XI -
Java System
For communication between ABAP System and XI there is a Proxy, however it is not working out.
The message from ABAP system does not go to XI.
I got the following message in SXMB_MONI of ABAP Sytem:

Someone has solved a problem like that?

Hi Fabio,
I would request to to check for two things,
1. Whats ur was version? Is it 640? else can you try to change the Commumnication channel in xi adapter to message protocal as xi2.0 ,, i think you used it as xi3.0
2. retest it.
3. If it still gets the same error refer the thread,

Proxy Problem The proxy server is refusing connections

I run Windows XP. I did have a Cybot backdoor Activity attack intercepted by Norton Internet Security and I used the Norton NPE to remove it from the computer. I do not know if this caused the proxy problem or not.
There is no proxy problem connecting to the internet through Internet Explorer just through Mozilla Firefox.
When Mozilla Firefox tries to connect to the internet I get the following message:
Firefox is configured to use a proxy server that is refusing connections.
Check the proxy settings to make sure that they are correct.
Contact your network administrator to make sure the proxy server is
working.
In Mozilla I click Tools, options, advanced, network, settings. Under settings Proxy is set on manual, it says that there is no proxy for the figures typed in.
So I click auto detect proxy and I then can connect to internet through Mozilla, however when I log out of the internet, the same proxy server issue is recreated.
What should the Proxy setting be?

You can find the connection settings in Tools > Options > Advanced : Network : Connection
If you do not need to use a proxy to connect to internet then select "No Proxy"
See "Firefox connection settings":
* https://support.mozilla.com/kb/Firefox+cannot+load+websites+but+other+programs+can

Immediate HELP in Tomcat 5 to Postgresql 7.4 database connectivity problem

Hi,
I failed to connect Tomcat 5.0.24 with Postgresql
7.4.2. The files created by me and the changes i had
made in the existing files are rates.jsp,
conversionDAO.java, web.xml and server.xml. The error
message on the top of the rest of it was "The value of
useBean class attribute converter.conversionDAO is
invalid". So far I found out that the coding for
database connectivity purpose in conversionDAO.java
cause the error. Another thing is Postgresql jdbc
driver is required to set in the CLASSPATH for the
java file to access the Postgresql database. I don't
know where should I put it in Tomcat for web
application. Anyway, I put it in
$CATALINA_HOME/shared/lib according the book i
refered. I do the database connectivity coding refer
to the Tomcat Kick Start book from Sams Publishing.
Below are the coding involved, please show me the

Hi Shriraj,
ensure that the installation path is correct. I only put /urs/sap/<SID> and you must put /usr/sap/<SID>/DV***/.
In my case with that the setup returns all in green.
I hope it helps you

SIMPLE Database Design Problem !

Mapping is a big problem for many complex applications.
So what happens if we put all the tables into one table called ENTITY?
I have more than 300 attributeTypes.And there will be lots of null values in the records of that single table as every entityType uses the same table.
Other than wasting space if I put a clustered index on my entityType coloumn in that table.What kind of performance penalties to I get?
Definition of the table
ENTITY
EntityID > uniqueidentifier
EntityType > Tells the entityTypeName
Name >
LastName >
CompanyName > 300 attributeTypes
OppurtunityPeriod >
PS:There is also another table called RELATION that points the relations between entities.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
check the coloumn with WHERE _entityType='PERSON'
as there is is clustered index on entityType...there
is NO performance decrease.
there is also a clustered index on RELATION table on
relationType
when we say WHERE _entityType ='PERSON' or
WHERE relationType='CONTACTMECHANISM'.
it scans the clustered index first.it acts like a
table as it is physically ordered.I was thinking in terms of using several conditions in the same select, such as
WHERE _entityType ='PERSON'
AND LastName LIKE 'A%' In your case you have to use at least two indices, and since your clustered index comes first ...
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Have you ever thought of using constraints in your
modell? How would you realize those?
...in fact we did.We have arranged the generic object
model in an object database.The knowledge information
is held in the object database.So your relational database is used only as a "simple" storage, everything has go through your object database.
But the data schema is held in the RDBMS with code
generation that creates a schema to hold data.If you think that this approach makes sense, why not.
But in able to have a efficent mapping and a good
performance we have thought about building only one
table.The problem is we know we are losing some space
but the thing is harddisk is much cheaper than RAM
and CPU.So our trade off concerated on the storage
cost.But I still wonder if there is a point that I
have missed in terms performance?Just test your approach by using sufficiently data - only you know how many records you have to store in your modell.
PS: it is not wise effective using generic object
models also in object databases as CPU cost is a lot
when u are holding the data.I don't know if I'd have taken your approach - using two database systems to hold data and business logic.
PS2: RDBMS is a value based system where object
databases are identity based.we are trying to be in
the gray area of both worlds.Like I wrote: if your approach works and scales to the required size, why not? I would assume that you did a load test with your approach.
What I would question though is that your discussing a "SIMPLE Database Design" problem. I don't see anything simple in your approach when it comes to implementation.

Database connection problem when i try store the values in JTable

Hi Sir,
I have a database connection problem when i try to store the data's in a JTable.I think the problem is with in the database connection.I have used 3 vectors here.The database which i have used is

Thanx,

The problem is ResultSet.next() is not called.
Try this and modify the table creation as you need.
ResultSetMetaData rsmd=rs.getMetaData();
int cols=rsmd.getColumnCount();
     while(rs.next()) {
          for(int i=1;i<=cols;i++)
                    col.addElement(rsmd.getColumnName(i));
                    rdata.addElement(rs.getString(i));
          rows.addElement(rdata);
Hope this helps

WLI 7.0 samples database setup problem

I have just installed WL Platform 7.0. I want to run the WLI samples and did the following:
1. Started "Integration Database Wizard" for WLI samples and performed "SwitchDB"
- provided valid database properties for oracle. Completed successfully - config.xml
for samples is updated.
2. Ran RunSamples script - Gives database connect problems and database is not created.
The user/pwd/machine name/SID are all correct.
I observed that as part of "RunSamples", it again invokes "SwitchDB" (command I see
is "switchdb oracle"). This resets the database properties in config.xml to the defaults
- so obviously this is causing the connection problem.
Pls let me know what is going wrong here?
Thanks

Garf,
You are correct in your analysis. When you run the 'RunSamples' script,
it will call switchdb and this causes the 'defaults' to be set in
config.xml. Running the wliconfig utility is the customer experience
BEA would like to have with regard to setting up the database. However,
the RunSamples script has not been updated to correctly reflect that the
customer would have already performed this step. When RunSamples calls
switchdb, it is getting the defaults from the following location:
<USER_DEFINED_DOMAIN>/dbInfo/<DATABASE>/setDBVars and setDBVarsExt files
So for example, if you accepted the default user directory and your
BEA_HOME is C:/bea and you were using the EAI Domain template calling
your domain eaidomain and your are using Oracle, you should update the
following files:
C:\bea\user_projects\eaidomain\dbInfo\oracle\setDBVars.cmd and
setDBVarsExt.cmd
Edit these files to reflect your DB connection properties.
When RunSamples calls switchdb, these properties will be used to update
the wliPool in config.xml. I hope this helps and sorry for the
inconvenience.
Cheers,
Chris

Applet bypassing proxy

I have an applet behind proxy/firewall. My browser settings uses auto config and specifies the .pac file. But plug-in seems to always bypass the proxy even though the java console has the checkbox "Use browser settings" checked. Any extra config needed? I am using 1,4,2_08

Have you tried specifying your .pac file in "Automatic Proxy Configuration URL" field at the bottom of the "Proxy" tab in Java Control Panel? You'll have to uncheck "Use Browser Settings" checkbox first.

In the newest verion of Firefox did you fix the proxy problem?

I am using firefox 3.6 because of a proxy problem with Firefox 5 I want to upgrade but need to know if you fixed this problem before i do so.

You can find the connection settings in Tools > Options > Advanced : Network : Connection
If you do not need to use a proxy to connect to internet then select "No Proxy" if the default "Use the system proxy settings" setting doesn't work.
See "Firefox connection settings":

Database connectivity problem in applet, but connects successfully thru app

hi all
my following code works successfully in appletviwer...
but in browser (ie 6.0)it does not even show textarea and
gives error at status bar as "exception : java.lang.NullPointerException: null string"
there is no problem to registerDriver...
but error is at getconnection...
os: windows xp, database : oracle8i, web server: apache
my db server,web server and html,class file all are on same machine...
pls help...
what could be the problem? may i need to do some web server settings?
thanks in advance
//CODE
import java.sql.*;
import oracle.jdbc.driver.*;
import java.awt.*;
public class AppletJdbc extends java.applet.Applet
     public void init ()
          TextArea outtext= new TextArea();
          add(outtext);
          Connection conn;
          try
               // Load the Oracle JDBC driver
               DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
               conn = DriverManager.getConnection("jdbc:oracle:thin:@172.25.12.46:1521:test","scott","tiger");
               outtext.appendText("connected");
          catch(Exception e)
               outtext.appendText(e.getMessage());
}

hi
yes i am accessing it in browser by giving("http://172.25.12.46/myfile.html"),
i think problem nullpointerexception was with TextArea..
now i have removed textarea and displaying messages just by
System.out.println...
it is giving java.lang.SecurityException
changes required to do in C:\jdk1.3\jre\lib\security\java.policy file
to make applet run from appletviewer:
following permissions added:
grant {
permission java.util.PropertyPermission "oracle.jserver.version", "read, write";
grant {
permission java.net.SocketPermission "172.25.12.46", "accept, connect, listen, resolve";
is there any setting required to make for browser?
some of u have suggested me to use servelts...
actually i am developing project for my oraganization, which will be used in intranet only and not on internet...
is it necessary to use servelts or direct db connectivity thru applet will do?
thankx
