Jdbc and struts

Hi,
pls tell me where i can find simple examples for connecting oracle database using struts
regards,
dhanya

Hi Dhanya,
what container/server are you using? If you are using a Java web server or a Java EE application server, then you should not have to do any Oracle specific thing in your code. Create a datasource and use JNDI to look up the datasource(jdbc.sql.DataSource). Then call datasource.getConnection().
When you deploy, configure the datsource to connect to Oracle, for that matter any JDBC compliant database.

JDBC and Struts - how?

Hi, I am writing my first struts application. However despite all the great tutorials out there, I can't find any real examples on how to connect to a database using the <data-source> tags in the struts-config.xml file.
I know you provide details of the db as follows:
<data-sources>
<data-source
autoCommit="false"
description="MySql Database Configuration"
driverClass="org.gjt.mm.mysql.Driver"
maxCount="4"
minCount="2"
password="myPass"
url="jdbc:mysql://localhost:1526/myDB"
user="myUser"
/>
</data-source>
but then what?! Even if I can get this to work (which I can't!), how do I use the connection? What do I do with it then?
Many, many, thanks for any guidance.

The properties file is just used to store the data-source info as you have outlined.
<data-sources>
<data-source key="name" ... />
</data-sources>
Once you have defined all the parameters identifying your data source you need to retrieve it in the Action class or in the relevant model class - the later only works with Tomcat 4 and later, so check your web server, the first will (should?) work on all web servers.
//fetch the datasource
DataSource ds = servlet.findDataSource("name");
Once you have the DS you can create the connection where needed, if in the action class simple generate a connection object form the data source and do the JDBC required. Or as is preferable pass the data source to a model class and do it all there.
//pass DS to model
modelClass searchBean = new modelClass(ds);
Hopes this helps.

Help on RFC to JDBC and JDBC to RFC

Help on RFC to JDBC and JDBC to RFC
Hi Gurus
I have the scenario where an RFC will be triggered in SAP , to write to a DB2 database and insert new records in a table
and vice versa the JDBC has to read som data from a table based on a primary key, mark them as read for not be read next time and send the data to an RFC where a table in SAP will be updated.
I have never worked with JDBC before , pls advice.
is there any new issue to consider in PI 7.0 regarding JDBC
Thanks.

The requirement looks standard,
SEARCH IN SDN FOR JDBC scenarios,you will find many docs for sender as well as Receiver.

IDoc to JDBC and JDBC to IDoc Scenario

Dear All,
I am working on IDoc to JDBC and JDBC to IDoc Scenario.
I have to send Idoc from SAP to Non SAP system(.NET application) i almost configured in XI but still i don't know when my INTEGRATION will INVOKE how my data will proceed from IDOC to Oracle database(Through JDBC) and in case of revese how and when Data flow will start.
Does anyone have completed STEP by STEP scenario document for this?
How my Idoc will sent to XI?
How XI will pick up data from IDoc?
How XI will Convert data to JDBC and UPDATE in Oracle Database?
And i reverse case(JDBC to IDoc) when my INTEGRATION will INVOKE?
Where and When i can watch my process and data?
How can i test the whole integration?
I AM GETTING ERROR WHILE TESTING CONFIGURATION IN Integration Directory "Error while refreshing the XI runtime cache" and when i check this in SXI_CACHE it gives me error
"Unable to refresh cache "NO_BUSINESS_SYSTEM"
"Error during last refresh to cache"LCR_GET_OWN_BUSINESS_SYSTEM - NO_BUSINESS_SYSTEM"
Please solve all the above problems i will reward u points
thanks,
RP

JDBC and FTP sender channels stop polling

Hi,
We have a great volume of sender JDBC and FTP sender channels.
For this reason there is nothing unusual to have temporary error connections.
Several months ago, with an XI 3.0 system, sender channels recover its functionality automatically when temporary error connection is solved.
But now, he have migrate to a PI 7.1 sytem, and in the same scenario and configuration, sender channel stop polling after a temporary error . In cc monitor this channels remains in green status and there were no signs of stopped interfaces.
Timeouts are correctly defined and there is no difference between channel configuration in our Xi and PI system.
How to solve this problem?
Thanks, in advance.
Carme.

Thanks for your fast response, Stefan.
After writing this post, i ask the same question to our basis team and we are in the latest sp.
¿do you know if there is any note or can you provide me some additional information?

Adapter Limitations Of Sender JDBC and Mail Adapter

hi All,
could you tell me the limitations of JDBC and Mail Adapter .i need to document these details .
Regards
Vidya Sagar

HI Vidya,
If i was you, i would do a list of things that i would need about these adapters, o i would search the SAP.help documentation for a first view and later ask about this possibility. Another way is to read the SCN doubts about these adapters and you can find some problems. You should think about the PI version as well.

JDBC and Linguistic Sorting

The problem: oracle jdbc thin driver doesn't see environment variable NLS_SORT
Description:
We have a lot of code written in coldfusion and now we would like to switch form CF5 to CFMX. We use oracle thin driver to connect CFMX to oracle DB.
The problem is that "order by" doesn't work as earlier. It seems that it jdbc driver couldn't make linguistic sorting, only binary. I tried with different versions, classes12.jar and ojdbc14.jar (the newest from otn).
I know that i could solve problem if use sql function nlssort but it is not acceptable for us. We couldn't change all our source code. We would like to use env variable NLS_SORT to control this behaviour.
I also wrote small standalone java program to test this directly but it doesn't see NLS_SORT. sqlplus from same shell works well.
Is it possible to set oracle jdbc thin driver to use NLS env settings (NLS_SORT)?
If yes, how? If not, what is the way to do linguistic sorting using jdbc?
Thank you,
Zeljko

Zeljko,
I don't have an answer for you (sorry), but I can suggest some resources where you may find the answer (hopefully -- assuming you haven't already tried them).
The section entitled JDBC and Globalization Support in chapter 18 ("Advanced Topics") of the "Oracle9i JDBC Developer's Guide and Reference, Release 2 (9.2)".
[Note: Since I couldn't see any details in your post about which Oracle version you are using, I assumed it was 9.2. However, you can access Oracle documentation for all the latest versions from the [url=http://tahiti.oracle.com]Tahiti Web site.]
The Globalization Development Kit may be helpful.
The Java Developer Center
The Oracle JDBC FAQ
Good Luck,

How to make JDBC and SAP connectivity with VC 6.0

Thank you very much.....

Hi Deep,
There is a how-to posted on SDN regarding how to connect and configure the BI JDBC Connector.
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/6209b52e-0401-0010-6a9f-d40ec3a09424
This document describes the jdbc driver to use etc.
Hope this helps,

Which tutorials may you suggest for JDBC and servlets?

Hello, i would to learn about JDBC and servlets.
May you please suggest me a good tutorial(e.g.post me a link) in order to study for JDBC and servlets?
e.g. How to make a servlet etc.
Thanks, in advance!

I agree with PhHein, it's best to learn one technology and then the other. (Just my two cents, but start with JDBC from a simple standalone application, then when that is working, try to tackle Servlets, since you will need to also learn how to get them working in a container like Tomcat).
Here is a tutorial that has both concepts in it at the same time. Site is down now, but is usually up. http://www.roseindia.net/jdbc/jdbcconnectivity.shtml
Also, you will eventually want to download a J2EE container such as Tomcat or Jboss.

___Secure JDBC and Servlets___

Hey all! I have an applet that uses jdbc calls to an oracle database, and servlets calls to oracle's jserv servlet container. It has been requested to make these connections secure.
Can someone please point me into the right direction on information/documentation on performing secure jdbc and servlet calls.
Thanks!
