4-tiers architecture

Hello everybody
Can we said that we have a 4-tiers architecture whene we work with mapviewer (to show maps) and tomcat(to administrate data base as insert update and others) ?
thank's

According to your description, it seems to me that you have a 3-tiered architecture. You have the presentation (web browser + client side APIs), application (MapViewer server and other middle-tier applications), and the data tier (Oracle DB). Your Tomcat task could be a part of the presentation tier (with UI in a browser) and a part of application (data management) tier.

Two-tiered Architecture Setup

Hi All,
I need some help with setting up a two-tiered messaging architecture. I want to have a front end messaging server in a DMZ with a'real' IP-Address and an official FQDN (mx1.external.org) and a back end messaging server as mail store with a private IP-Address and private FQDN (mail.internal.pri). The front end server should do some spam/virus checking and then send the emails over to the internal server. Between the two is a packet filtering firewall. This setup works perfect with two Postfix servers but I want to try out messaging server so I wanted to ask for some documentation how this can be done. I already followed the documentation in chapter 16 (LMTP) of the messaging server administration guide, directory server and delegated administrator for user provisioning also work, but I obviously have difficulties in understanding the interrelationship between "mail host" "preferred mail host" and the FQDN of the external and internal messaging servers. In my current configuration I get
Recipient address: @mail.internal.pri.lmtp:uid@lmtpcs-daemon
Original address: [email protected]
Reason: Illegal host/domain name found
from the external server which I understand because of the private "pri" top level domain name. But when I change the mailhost to the external server the external server says (correctly) that the mailbox is on another host.
Can someone point me to some documentation where I can learn about all this or has a similar set up and can help?
Thank you.
Greetings,
Willi

Number of scokets for httpsession replication in multi-tiered architecture

 In the weblogic's document on clustering the
 section "Configuration Notes for Multi-tier Architecture" states
 In particular, during peak socket usage, each WebLogic Server in
 the cluster that hosts servlets and JSPs may potentially use a
 maximum of:
 Two sockets for replicating HTTP session states between primary
 and secondary servers.
 I don't understand why 2 sockets are required. Won't just one do the job. What's
 the 2nd one for?
 pradeep


 hi,
 The doc mentions toally 3 sockets. I have pasted the doc
 content FYI
 "In particular, during peak socket usage, each WebLogic Server in the cluster
 that hosts servlets and JSPs may potentially use a maximum of:
 Two sockets for replicating HTTP session states between primary and secondary
 servers, plus
 One socket for each WebLogic Server in the EJB cluster, for accessing remote objects
 Toally 3 sockets. 2 for httpsession replication and 1 for accessing remote objects.
 Why 2 sockets are required for replicating HTTP session states between primary
 and secondary servers

Tiered Architecture and Clustering

Hi,
 Was wondering if anyone had problems setting up clustering in a
 tiered environment. What we are looking to do is setup a load balancer
 in front of a weblogic presentation tier (Servlets and JSP) that in
 turn connect to a clustered application tier of EJB's. Just some
 random thoughts:
 1) Does the replica aware stub live in the presentation tier?
 2) Does it make sense to put another load balancer between tier's? Or
 just let the stub handle the load balancing?
 Curious to know if anyone else has setup a similar configuration.
 Regards,
 Rick Mitterer


I have seen several such setups. You do not usually have a dedicated
 hardware load balancer between the JSP/Servlet container and the EJB
 container. The replica-aware stub is where the EJB client is, which is the
 JSP/Servlet container.

Developer 6.0.5 three-tiered architecture application deploy on web

Sir/Miss,
There are two questions.
1.In browser I can't use 'button'.
2.In browser I can't use 'treeview'

Operating System Windows NT 4.0 with service pack 3
Netscape Communicator 4.04 (with the JDK 1.1 patch)

May be I can answer part of the questions. First, when you use Developer 6 to create either Forms or Reports, the application can run under either client/server or web environment. To run it under web environment, you need to have OAS as middle tier. The front end only need to have jave-enabled browser. JInitiator act as a bridge in between. You need only have Server side deployment.
For JDeveloper, it generates java class for you, it requires you understand java, write some java codes.
For neither tool, you don't need any client side or server-side license. Just the cost of the tool.

N-tiered programming in Java

I'm new to Java/JSP and am looking for tutorials and examples of how to do web n-tiered programming in Java. In .NET, I've often separated the web presentation layer from the business logic and data access layers. How do you accomplish this in Java? Thank you.

What do you mean "accomplish"? You write java classes. N-tiered architecture is not limited to specific programming languages. It is a paradigm.

SSO using Kerberos with SAP Logon Tickets

Hi,
I am creating a Repository Manager for the Portal Knowledge Management System and I want to use SSO to a backend IIS application and I have a few questions here.
I have a three tiered architecture.
A. The presentation tier (SAP Portal which has my Repository Manager implementation)
B. ASP.NET web service data layer.
C. Backend document management system which runs on IIS.
I have installed the ISAPI filter on my ASP.NET application server and have enabled this HOST account for delegation in MSAD 2003. Server B will use Kerberos constrained delegation to access Server C, which is an IIS backend server.
My question is how do I pass an SAP Logon Ticket to an ASP.NET web service request from my Repository Manager implementation? Basically how do I just make an HTTP request to an ASP.NET application from some portal iView or WebDynPro code and pass along the SAP Logon Ticket in the request so it can be interpreted by the ISAPI filter on the IIS server. Does anyone have any sample code or an application here that does this?
Thanks,
Scott

Hi Scott
Did you managed to find out anything regarding how to pass SAP Logon ticket to ASP.NET Webservice. Can you share it with me?

How deploy 6i Forms Fmx trought Application Server 10g

Hello every one,
Situation :
In my company, we have a software developed by a team using Oracle Forms 6i, the application is connected te Oracle 9i Database and every thing works well.
Problem :
I was able to upgrade the database from 9i to 10g. But my question : is it possible to deploy all the Forms (fmx 6i version) on Application Server 10g. I want to use the 3-tiers architecture.
Take note that i have not the fmb source files. Just the FMX (about 40 files)
If yes, can you explain also how to proceed (tools to install on Application Server) and how to setup the connection between the 3 tiers throught a LOCAL NETWORK.
Regards
Kira

You will at least need to recompile all those *.fmb to *.fmx in the version of the App server you will be using.
We have a forms6 c/s application we are migrating to forms 11g and it almost that easy (except for changes in how you launch reports).
The application server is setup alot like the client/server side of forms is, it needs a tnsnames.ora that points to the database and it needs to know where you will be storing the forms and report. Looks for any *.fmx and that will be the default location.

Update row in a table based on join on multiple rows in another table

I am using SQL Server 2005. I have the following update query which is not working as desired.
UPDATE DocPlant
SET DocHistory = DocHistory + CONVERT(VARCHAR(20), PA.ActionDate, 100) + ' - ' + PA.ActionLog + '. '
FROM PlantDoc PD INNER JOIN PlantAction PA on PD.DocID = PA.DocID AND PD.PlantID = PA.PlantID
For each DocID and PlantID in PlantDoc table there are multiple rows in PlantAction table. I would like to concatenate ActionDate and ActionLog information into DocHistory column of DocPlant table. But the above update query is considering only one row from
PlantAction table even though there are multiple rows that match with DocID and PlantID.
DocHistory column is of type NVARCHAR(MAX).
How do I fix my query to achieve what I want ? Thanks for the help.

UPDATE DocPlant
SET DocHistory = DocHistory + CONVERT(VARCHAR(20), PA.ActionDate, 100) + ' - ' + PA.ActionLog + '. '
FROM PlantDoc PD INNER JOIN PlantAction PA on PD.DocID = PA.DocID AND PD.PlantID = PA.PlantID
We do not use the old Sybase UPDATE..FROM.. syntax. Google it and learn how it does not work. We do not use the old Sybase CONVERT() string function. You are still writing 1950's COBOL with string dates instead of temeproal data types.
You also did not post DDL, so we have to guess about everything. Does your boss make you work without DDL? How do you do it?
>> For each DocID and PlantID in PlantDoc table there are multiple rows in PlantAction [singular name?] table. I would like to concatenate ActionDate and ActionLog information into DocHistory column of DocPlant table. <<
Why? What does this new data element mean? This is like dividing Thursday by Red and expecting a reasonable answer. Now, non-SQL programmers who are still writing COBOL will violate the tiered architecture rule about doing display formatting in the database.
If you will follow forum rules, we can help you.

Getting the data for last month of every year

Hi,
How to declare the date if we want to pull the data from the December of every year.
For example if the query is run in march 2015 and they want the historical data it should pull only the data from dec 2014.
In the same way if they ran the query in future jun 2016 and if they want to historical data it should pull only data from dec 2015.
It should not coded manually. Please help me with date format that need to used.

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for:
https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
A table has to have a key to be table. Here is my guess at a repair job:
CREATE TABLE Test_Data
(pu_id INTEGER NOT NULL
REFERENCES PU(pu_id),
pu_date DATE DEFAULT CURRENT_TIMESTAMP NOT NULL,
PRIMARY KEY (pu_id, pu_date),
x_count INTEGER,
y_count INTEGER);
Identifiers are not numeric in a good schema. What math do you do with them? They are also the key in the table that models the entity they identify. Where is the PU table (and what is a PU anyway)?
INSERT INTO Test_Data
VALUES
(28, '2014-01-01', 10, 20), -- crap! No key in this mess!!
(28, '2015-01-01', 30, 20), --
(28, '2014-12-12', 10, 20),
(28, '2015-02-02', 10, 20);
A PIVOT is not a query and not even part of SQL. It is how Microsoft programmers who do not know RDBMS or have a report writer violate the tiered architecture of SQL. We also do not use XML mixed in SQL. It is a bitch to maintain, has poor performance and again
violates the tiered architecture principle.
A query is not sorted because it is a table. A file in COBOL can be sorted and that seems to be what you really want to write.
Old COBOL love the Sybase CONVERT() string function to avoid SQL temporal data.
We never use SELECT * in production code; Google it. Not only are you generating code, you are generation bad code.
Since SQL is a database language, we prefer to do look ups and not calculations. They can be optimized while temporal math messes up optimization. A useful idiom is a report period calendar that everyone uses so there is no way to get disagreements in the DML.
The report period table gives a name to a range of dates that is common to the entire enterprise.
CREATE TABLE Month_Periods
(month_name CHAR(10) NOT NULL PRIMARY KEY
CHECK (month_name LIKE <pattern>),
month_start_date DATE NOT NULL,
month_end_date DATE NOT NULL,
CONSTRAINT date_ordering
CHECK (month_start_date <= month_end_date),
etc);
These report periods can overlap or have gaps. I like the MySQL convention of using double zeroes for months and years, That is 'yyyy-mm-00' for a month within a year and 'yyyy-00-00' for the whole year. The advantages are that it will sort with the ISO-8601
data format required by Standard SQL and it is language independent. The pattern for validation is '[12][0-9][0-9][0-9]-00-00' and '[12][0-9][0-9][0-9]-[01][0-9]-00'
This will port and waste time calling string function row by row.

This is so very, very wrong! A column is an attribute of an entity. The idea that you are so screwed up that you have no idea if you want
the shoe size, the phone number or something else at run time of this entity.
In Software Engineering we have a principle called cohesion that says a model should do one and only one task, have one and only one entry point, and one and only one exit point.
Hey, on a scale from 1 to 10, what color is your favorite letter of the alphabet? Yes, your mindset is that level of sillyity and absurdity.
Do you know that SQL is a declarative language? This family of languages does not use local variables!
Now think about “month_val” and what it means. A month is a temporal unit of measurement, so this is as silly as saying “liter_val” in your code. Why did you use “sp_” on a procedure? It has special meaning in T-SQL.
Think about how silly this is:
SET @month_val = 'Month' + CAST(@month_nbr AS VARCHAR(2));
We do not do display formatting in a query. This is a violation of at the tiered architecture principle. We have a presentation layer. But more than that, the INTERVAL temporal data type is a {year-month} and never just a month. This is fundamental.
We need to see the DDL so we can re-write this mess. Want to fix it or not?

Publication of the big-sized Enterprise projects from Project Professional 2013 to Project Server 2013 takes about 60+ minutes.

Dear Sirs,
I need your support over the following MS EPM 2013 issue:
Publication of the big-sized Enterprise projects from Project Professional 2013 to Project Server 2013 takes about 30+ minutes. We
need to reduce this total publication time down to acceptable working values 10+- minutes.
Environment information:
Single App Server (Virtual): 16 Gb RAM, x64 4xCPU, HDD > 50 GB free disk space, OS Windows Server 2012 Standard Edition x64 Service
Pack 1, MS SharePoint Server 2013 and MS Project Server 2013 with CU December 2013 (KB 2850024) applied.
Single RDBMS MS SQL Server (Virtual): 8 Gb RAM, x64 4xCPU, HDD > 200 GB free space, OS Windows Server 2012 Standard Edition x64 Service
Pack 1, MS SQL Server 2012 x64 SP 1 Enterprise Edition.
We have 1Gbit LAN between APP, DB server and 1Gbit LAN between APP and Proj Prof Client.
Yes, we are on the way of migrating to the Prod environment
with 3-tiered architecture (with SP1 slipstream and CU December 2014 applied), but this issue also
presents there.
Project’s file information:
Tasks in the file: [~4900], resources in the file [~396] enterprise task’s custom fields used in the file [~23].
Project save procedure for this new project would last about 7 minutes. Project publication would last about 47 minutes. We noticed that
tasks synchronization process took about 1 second for each ~2,5 tasks, to add them to the sharepoint tasks list. So for all 5148 tasks it took about 5148/3/60 = 34 minutes. Other 13 min was used for reporting database publication and other tasks relevant
for new sharepoint site creation.
Case 1: Issue description:
During the Enterprise project’s file save and publication we have the following sharepoint 2013 log messages:
07.31.2014 12:43:17.22 Microsoft.Office.Project.Server (0x0358) 0x3D5C SharePoint Foundation Monitoring b4ly High Leaving Monitored Scope
(Persisting list changes). performing time =376.068676326181 22dca99c-4696-70f1-e9e2-06851d0bcffd
07.31.2014 12:43:17.69 Microsoft.Office.Project.Server (0x0358) 0x3D5C SharePoint Foundation Monitoring b4ly High Leaving Monitored Scope
(Persisting list changes). performing time =361.652807828928 22dca99c-4696-70f1-e9e2-06851d0bcffd
It shows that sharepoint spend at least ~350 milliseconds (or 0,35 sec*4900 tasks = 1715 sec, or 28,5 min) for each task update during
project publication. And we also have another log file that shows that about 0,7 sec (or 0,7 sec*4900 tasks = 3430 sec, or 57 min) sharepoint spend for save each task in project file to project server. So total save and publication time more then 60+ minutes
for that project file. The same result we have even if user didn’t do any changes at the project file.
We use only enterprise projects (dbo.MSP_EpmProject_UserView.projectvisibilitymode = «False»), and do not use sharepoint tasks lists,
but the synchronization between MSP Plan and SharePoint tasks list works at any case.
Case 2: Issue description:
- For the second test we created a new project with new sharepoint project’s site on basis of our «issue» project, with total amount
of tasks in it of 5148 (yes, we increased the tasks list default limit at the sharepoint site up to 6000 items in it – standard limits for sharepoint view list – 5000 items).
- Project save procedure for this new project would last about 7 minutes. Project publication would last about 47 minutes. We noticed
that tasks synchronization process took about 1 second for each ~2,5 tasks, to add them to the sharepoint tasks list. So for all 5148 tasks it took about 5148/3/60 = 34 minutes. Other 13 min was used for reporting database publication and other tasks
relevant for new sharepoint site creation.
-Then we deleted the
tasks list for that new test project from the sharepoint site and republish the project plan one more time. This time project save procedure took about 7 minutes, project publication about 2 minutes and 3 minutes for other relevant queue jobs. So total time
is 12 minutes.
As a conclusion: yes, we have determined
the exact problem - during synchronization process (from Project Server to SharePoint) it perform copying all tasks and related data from Project to SharePoint in spite of fact that you changed only ONE task or ALL of them. At any case, synchronization will
copy ALL of them from Project Server to SharePOint task’s list.
Our workaround is to disable the task’s synchronization for such big-sized project plans:
– to delete the SharePoint «tasks» list at the SharePoint site tied with project plan.
- or deattach the SharePoint site from the project plan.
Thank you for reading this topic, please if you also forced with such issue provide us any known workaround or maybe any official response
\ feedback from MS about it.
Thank you in advance,
Best Regards, Andrey

Regarding my topic, I also said that every time when sync works it updates All items from project’s plan at Project Server to corresponded task’s list at SharePOint server. Inspire of the fact that you changed only One task or group /
all of them at your project’s plan.
And it seems to me and my colleagues that it’s probably (maybe) a “bug” at the product. Here is what we have if looked a little bit closer to the code:
Share Point determines what task to sync from Project’s plan to sharepoint list. To do that sharepoint needs to know was that task changed or not, based on the following fileds (check SQL stored procedure “[MSP_READ_TASKS_FOR_SYNCRONIZATION]”):
TASK_UID TASK_NAME TASK_START_DATE TASK_FINISH_DATE TASK_PCT_COMP TASK_PARENT_UID TASK_OUTLINE_NUM
WSS_LISTITEM_UID TASK_ID TASK_IS_ACTIVE
We noticed that at any case synchronization performs for all tasks, EXCEPT the ROOT one. Then we looked at the comparison of TASK_PARENT_UID field. So sharepoint compares TASK_PARENT_UID with ParentID (this is internal name for lookup
field “Tasks” at the Sharepoint, and it stores their values at the format "ID;#Title").
And comparison performs like following:
SharePoint looks for Task at the Tasks’s list corresponded to Project’s plan with ID represented at the TASK_PARENT_UID field. Then it takes SharePoint ListItem ID (“int” type) and store it to the “num” parameter;
num = this.GetCachedListItemByUniqueId(listItem.ParentList, nullable.Value).ID;
2.Then it compares “num” with task’s “ParentID” at SharePOint as follow with operator “!=”:
((SPItem) listItem)["ParentID"] != (System.ValueType) num
3. If comparison was success (true) – then it tell us that values (at the Project’s plan for tasks) was changed, then it need to be synchronized. Corresponded Method setup “true” flag, and then returns it.
The “bug” is that this expression at the Step 2 will always return “true”, because in fact it compares “string” (see above – that this is lookup field at SharePoint side)
with “number”. For example if the parant task ID is “55”, then we get:
"55;#Task 1" != 55
And by the rules of .Net the “string” will never equal “number”
Furthermore this is approved by the SharePoint logs:
In that case we always get the note “Setting ParentID to” at the logs (we see it if turns on Verbose for “Project Server” -> “Sharepoint Integration” category).
So at any case of publishing project’s plan we always get that note at the logs for tasks that have Parent task, and we have Parent for all of them EXCEPT the ROOT one, exact logs represented further:

bool flag = false;
int index = taskDS.Tables[0].DefaultView.Find((object) DataRowExtensions.Field<Guid>(row, "TASK_PARENT_UID"));

int num = -1;
if (listItem.Fields.ContainsField("ParentID"))
if (nullable.HasValue)
try
// STEP 1
num = this.GetCachedListItemByUniqueId(listItem.ParentList, nullable.Value).ID;
catch (ArgumentException ex)
if (redoEntries != null)
if (!redoEntries.ContainsKey(DataRowExtensions.Field<Guid>(row, "TASK_UID")))
redoEntries.Add(DataRowExtensions.Field<Guid>(row, "TASK_UID"), listItem);
//STEP 2
if (num != -1 && ((SPItem) listItem)["ParentID"] != (System.ValueType) num)
((SPItem) listItem)["ParentID"] = (object) num;
ULS.SendTraceTag(845443U, (ULSCatBase) ULSCat.msoulscat_PS_ProjectSharepointIntegration, ULSTraceLevel.Verbose, "Setting ParentID to {0}", new object[1]

Any thoughts about it would be much appreciated!

Printing/report writing

Could anyone recommend any good printing/report writing tools that can be
integrated with Forte? I have found these capabilities to be less than
satisfactory from within Forte itself.

How to use convert function in my issue

CASE WHEN RATE_CODE='BS' then '0.00' ELSE ((COST)/TOTAL_UNITS)end AS COST this function is showing when rate_code='Bs' then 0.0000. i want only 0.00 in this.
thank you all
actually my query is getting when RATE_CODE='BS' IS THEN 0.0000.but i want this value 0.00 to display.how can i achive

We do not do display in the database; we have a presentation layer. This is the most basic principle of any tiered architecture. I will guess you have been programming for a only a few weeks, but t6his is usually covered in the
early part of any course.
You probably need to read and download the PDF for:

CLOB / Charset / Java / Unix Issue

Hi,
I'm encountering the following problem.
I'm working on a 3-tiers architecture with an Oracle Database (8.1.7)
a Weblogic application server 6.1 SP4 and a Web server under Aix 4.3
(all 3 are under AIX 4.3 on the same platform).
My application has a web interface that allows users to upload files
to the server from their PC clients and a webbrowser, that insert each
file into a oracle Clob (via Java Code) and that call a stored
procedure (with java code again) to extract this clob to a file
(UTL_file package), then, the extracted file is processed line by line
and information inserted in others tables.
The issue is that some characters (acute, grave accent ....etc)
appears as question marks in the database or that some date from the
file can't be processed because they are structured as DD/MM/YYYY
(french notation, but that normal I'm from france).
I first thougt of an NLS_LANG problem but on the weblogic server it is
set to french_france.WE88859P15 that seems to be right and the same
the database configuration.
I then tried to performs some conversion when the clob data were
extracted to file (from WE88859P15 TO CP152 or vice-versa) with the
oracle convert function but it seems that it doesn't work.
An other but coherent symptoms is that the extracted files (from the
clob columns) seems not to be fine (accent are not recognized).
This is the java code used to load file to clob (on the weblogic
server side)
con = dbHandle.getAdminConnection();
con.setAutoCommit(false);
/// NEW IMPORT
// int taskId = DBTools.getOraSeqValue("vtr.VTR_SEQ_LOG_IMPORT",
DBTools.NEXTVAL,con);
int taskId = DBTools.getOraSeqValue(SqlQueryDefinition.seqLogImport.toString(),
DBTools.NEXTVAL,con);
Debug.out.println("taskId " + taskId);
// String cmd = "insert into vtr.vtr_log_import
(cod_task,DTE_DEBUT,lob_imp,lob_rej,lob_log, txt_nom_fic_orig,
txt_utilisateur) " +
// "values ("+ taskId
+",sysdate,empty_clob(),empty_clob(),empty_clob(), '"+file+"','"+
((UserBean)request.getSession().getAttribute("userbean")).getIdentifier()+"')";
// stmt = con.createStatement();
// stmt.executeQuery(cmd);
// stmt.close();
pstmt = con.prepareStatement(SqlQueryDefinition.initLigneImport.toString());
pstmt.setInt(1,taskId);
pstmt.setString(2,file);
pstmt.setString(3,((UserBean)request.getSession().getAttribute("userbean")).getIdentifier());
pstmt.executeQuery();
pstmt.close();
con.commit();
// Writing CLOB
// cmd = "SELECT cod_task,lob_imp,lob_rej,lob_log FROM
vtr.vtr_log_import WHERE cod_task="+ taskId +" for update";
// stmt = con.createStatement();
// rset = stmt.executeQuery(cmd);
pstmt = con.prepareStatement(SqlQueryDefinition.setBlobImport.toString());
pstmt.setInt(1,taskId);
rset = pstmt.executeQuery();
rset.next();
File csvFile = new File(localFile);
System.out.println("csvFile length = " + csvFile.length());
File unixFile = new File(localFile+".ux");
Tools.dos2Unix(csvFile, unixFile);
FileInputStream instream = new FileInputStream(unixFile);
// support Weblogic
clob = ClobComponent.factory(DBUtil.getInstance().isWebLogicPlatform());
clob.setClob(rset,2);
outstream = clob.getAsciiOutputStream();
size = clob.getBufferSize();
byte[] buffer = new byte[size];
int length = -1;
while ((length = instream.read(buffer)) != -1)
outstream.write(buffer, 0, length);
instream.close();
outstream.close();
rset.close();
// stmt.close();
pstmt.close();
rset=null;
// stmt = null;
pstmt=null;
con.commit();
// IMPORT
cs = con.prepareCall(SqlQueryDefinition.importStoredProc.toString());
index = 1;
cs.setString(index++, fullPath); // 1
cs.setString(index++,
((UserBean)request.getSession().getAttribute("userbean")).getIdentifier());
// 2
cs.registerOutParameter(index++,java.sql.Types.VARCHAR); // 3
cs.registerOutParameter(index++,java.sql.Types.VARCHAR); // 4
cs.registerOutParameter(index++,java.sql.Types.NUMERIC); // 5
cs.setInt(index++, taskId); // 6
cs.executeQuery();
String fichier1 = cs.getString(3);
String fichier2 = cs.getString(4);
int returnCode = cs.getInt(5);
System.out.println("returnCode/fichier1/2 : " + returnCode + " & "
+ fichier1 + " & " + fichier2);
cs.close();
con.commit();
This is the PL/SQL code used to unload clob to dile (on the oracle
side)

+ 1;
IF nvl_pos > nvl_clob_length
THEN

END IF;
END LOOP;
UTL_FILE.fclose (file_handle);
END writeToFile;
I'm using the oracle thin driver but it's not set in classpath maybe a
problem with that ?
<JDBCConnectionPool DriverName="oracle.jdbc.driver.OracleDriver"

Targets="myserver" TestConnectionsOnRelease="true"
TestConnectionsOnReserve="true" TestTableName="dual"
URL="jdbc:oracle:thin:@localhost:1521:ssr"/>
Maybe a problem with the properties of weblogic.codeset (I don"t set
it) ?
Many thanks in advance, I have no idea even if I suspect the java
store to file or the UTL_file extration to file steps to be in cause !

Hi,
I'm encountering the following problem.Hi. The first thing I'd do to narrow the search is to see if my Java code
worked in a standalone program, without weblogic in the picture. Once
you get Oracle's JDBC driver to work with Oracle's DBMS, it shouldn't
be hard to get the same stuff to work inside weblogic, or find out why it
doesn't.
