Com.microsoft.jdbc.sqlserver.SQLServerDriver and ntext,text
I'm using the com.microsoft.jdbc.sqlserver.SQLServerDriver driver with SQL2000. In my table I have one ntext(i dont mind changing this to text datatype) column and to retrieve the data I'm using getAsciiStream(colname). I also tried getCharacterStream(colname).
Even though I have data in the table, the method restult.getAsciiStream() brings nothing. I need some help in knowing how to retrieve the data when using ntext or text datatype in SQL server.
Also I need some smaple code of how to write the data back to the table.
Have you tried getString() ?
I remember using this method once to read an ntext field from a MSSQL2K db. If you explicitly need a stream I recomend you to try a binary stream, binary streams works most of the time, then wrap it in a Reader.
Regards,
Rivas.

But if I use sun.Jdbc.Odbc driver it works.

Com.microsoft.jdbc.sqlserver.SQLServerDriver not found
Hi All,
I have created an Entity Bean to connect to my Database...when i use the inbuilt OC4J instance of JDeveloper my client application can easily connect to the database using tis Beab....But while using an external oc4j server downloaded explicitly...it says...
java.lang.ClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver
I have already set the classpath for msbase.jar, mssqlserver.jar and msutils.jar files....
even then i am facing the same problem...
Please help me out....its very urgent....
Thanx in advance to all....
PraveenUsing the Enterprise Manager web interface navigate to the 'Administration' tab.
Under 'Administrative Tasks' -> 'Properties' you should find Shared libraries. Be SURE that your libraries are in fact located there.
I'm assuming you have also set up Datasources and connections pools for your database? Verify that they are showing the correct SQL Server driver class.
Hope this points you in the right direction! -
Hi...Experts....
Requirement:
From our PI 7.1 System we have to connect to MS-SQL Server 2000 using JDBC.
Execution :
We have downloaded
Microsoft SQL Server JDBC Driver 3.0 ...and...Microsoft SQL Server JDBC Driver 2.0 ( We mean we tried both drivers)and deployed using JSPM in PI system
To deploy this ..We used & reviewed the following notes
Note 0000831162 - FAQ: XI 3.0 / PI 7.0 / PI 7.1 JDBC Adapter
Note 0001138877 - PI 7.1 : How to Deploy External Drivers JDBC/JMS Adapters
Note 0000850116 - XI 3.0 / PI 7.0 JDBC Adapter: Type 2 JDBC Driver Deployment
Note 0001123333 - Redeploying same component with JSPM
Issue Observation Path :
in JSPM ...The deployment is successfull
But in
>Runtime Workbench NetWeaver Administrator
>>Component Monitoring
>>>Compnenet with status ..ALL...[DISPLAY]
>>>Adapter Engine
>>>>Communication Channel
We continuioulsy see the following error
ERROR :
Error during database connection to the database URL 'jdbc:microsoft:sqlserver://101.197.135.118:1433;databaseName=LWV' using the JDBC driver 'com.microsoft.jdbc.sqlserver.SQLServerDriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Cannot establish connection to URL 'jdbc:microsoft:sqlserver://101.197.135.118:1433;databaseName=LWV': SAPClassNotFoundException: com.microsoft.jdbc.sqlserver.SQLServerDriver'
ERROR:
In this Juncture...We have 2 queires.
01. How to make the Deployed JDBC Driver avaialbiliy in the system.
02. Any other alternate way to make sure our self deployed JDBC well installed in system and can be used from PI Console.
Regards
PRImran ...Thank U Very much...
We could able to move forward.
as in Java Instance :
In directory : DRIVE:\usr\sap\<SID>\DVEBMGS<NN>j2ee\cluster
We can see : instance.properties
We copied the 3 files (01) sqljdbc4.jar, (02) msutil.jar, (03) msbase.jar into a directory like
DRIVE:\usr\sap\<SID>\DVEBMGS<NN>j2ee\cluster\bin\ext\com.sap.aii.adapter.lib\lib\
In the "configtool" we configured these 3 jar files in class path like :
DRIVE:\usr\sap\<SID>\DVEBMGS<NN>j2ee\cluster\bin\ext\com.sap.aii.adapter.lib\lib\sqljdbc4.jar;
DRIVE:\usr\sap\<SID>\DVEBMGS<NN>j2ee\cluster\bin\ext\com.sap.aii.adapter.lib\lib\msutil.jar;
DRIVE:\usr\sap\<SID>\DVEBMGS<NN>j2ee\cluster\bin\ext\com.sap.aii.adapter.lib\lib\msbase.jar
and restarted the Instance, which in turn updated the instance.properties
and we could see the errors stopped coming in the "XI Runtime WorkBench - Component Monitoring"
We could see as
>>>Processing started
>>>Processing finished successfully
>>>Polling interval started. Length: 60.0 seconds
So we understood, the connection could db server and we conformed we moved a head on the issue

Lukehi Luke,
I dont know if it is in someway related to ur jdk version..
but your error message seems to be
java.lang.ClassNotFoundException:com.microsoft.jdbc.sql
erver.SQLServerDriver
Plz consider this possibility if
u might have given the classname wrong as
com.microsoft.jdbc.sqlerver.SQLServerDriver
which throws the exception as shown in the error message!!
try giving the correct classname as com.microsoft.jdbc.sqlserver.SQLServerDriver
which may solve your problem..
cheers,

Missing package com.microsoft.jdbc.sqlserver.SQLServerDriver
hi all!!
I don't know what's happens, so I hope you can help me...
I try to connect with a jsp-Application a ms sql server over jdbc.
At microsoft.com, I found a jdbc-driver for the spezific sql server and I install it.
So after that I tried different ways to connect the server but every time it fails...
I seams, that the package com.microsoft.jdbc. etc were missing, because my ide doesen't highlight such one package...
So what do you mean...
Over odbc my application runs fine, but that's not the requirements...
It should run with an direct connection to the server...
thx

Hello,
(Running NW04SP14)
I am trying to use the jdbc class in my code as follows:
Class.forName("com.sap.portals.jdbc.sqlserver.SQLServerDriver");
I am getting a ClassNotFoundException.
Could you please tell me what do I need to do to import this class for all my portal components?
Do I need to physically include a jar file, if so where can I find it?
Should I include a sharing reference in my code?
Thanks.Hi Detlev,
I'm asking to you about a problem with connection that since many days I'm not able to solve. I hope in your help regarding this.

Has anybody used the microsoft JDBC 2.0 driver for sql server 2000?
Hi,
Has anybody used the JDBC 2.0 driver for sql server 2000 downloadable from the
microsoft website?When I try using it with WL 6.1 sp1 it says it can't load the
driver.I try viewing the class file from the jar file using the jar utility it
gives an unknown Zip format error.Anybody has any solution for this ?If anybody
has managed to work with this microsoft driver i will be grateful if they provide
me with a solution.
Thanks
ThomasHello Thomas,
You may want to download the driver again and install it again.
heres a sample xml tag in the config.xml:
<JDBCConnectionPool
DriverName="com.microsoft.jdbc.sqlserver.SQLServerDriver"
InitialCapacity="3" MaxCapacity="12" Name="MSpool"
Password="{3DES}fUz1bxR0zDg=" Properties="user=uid"
Targets="myserver"
URL="jdbc:microsoft:sqlserver://mydbserver:1433"/>
ensure that you follow the instructions from Microsoft. For using 2000
driver you will need to have
Install_dir/lib/msbase.jar and Install_dir/lib/msutil.jar in addition to
Install_dir/lib/mssqlserver.jar in the CLASSPATH.

Question about load Microsoft JDBC driver for Sql server 2000
Hello,
I have some problem while trying load the sqlserver2000 jdbc driver
My program is a third party application and it works with the other type 4 JDBC driver well. So I tried to use Microsoft SQL server 2000 JDBC driver instead.
I installed JDBC driver and set up the classpath.
My error message is:
"Driver class 'com.microsoft.jdbc.sqlserver.SQLServerDriver' could not be loaded"
Is above message means that my classpath setup correctly but the application could not load the class or the application could not find the jar file which containes the driver class?
By the way, the third party application I was using to load this JDBC driver does not certified to use microsoft JDBC driver. But I don't think it matter?
Thanks for your help

That is an unusual message. Presumably you did not see "NoClassDefFoundError". If you see that it means the class could not be found.
Is above message means that my classpath setup
correctly but the application could not load the class
or the application could not find the jar file which
containes the driver class?
By the way, the third party application I was using to

It could. Perhaps the app expects a certain functional level and the driver doesn't support that. And so it bails with the message that you see.
Or it could mean that you have do something special because it has its own class path, and the driver is not in that.
Maybe you are looking for
