Putting JDBC drivers in common/lib
Is it mandatory to put the JDBC drivers in the common/lib? Or can I put the JDBC drivers in each context's WEB-INF/lib? As long as I can remember I read somewhere that these drivers most be placed in the common/lib directory cause otherwise it introduces class loader problems. But what if I have two different Web applications and each of them use a different version of the JDBC driver for the same RDBMS?

Re: Putting JDBC drivers in common/lib
if you are using jndi, i think they have to be in common/lib. If not, they can go in WEB-INF/lib instead.

Re: comparison of Type 4 JDBC drivers
I cannot thank you enough Tuncay Baskan. We were about to switch to Tomcat from Jrun4 and found that the MS drivers were noticably slower. Your tip to use jTds probably saved me a few days of testing. We also tried DataDirect, but they will not sell you just a driver unless you have some distribution agreement and a lot of money.

RE: comparison of Type 4 JDBC drivers
This is the JVM catching an exception/access violation in the native code outside of the JVM. The problem is probably in native code in the driver or any jni code you may be using. If you are not using any jni to wrap native code that is custom to your site, you should look at how you are calling the JDBC. You may be sending NULL values or incorrect format for what the ODBC driver is expecting and causing the access violation. I had something similar and it was stack corruption in my native code.

I am basically just trying to setup a connection pool as in the documentaion. I am
relatively new
to java but have several years of C/C++. I am also a System Engineer during the day,
but I am
writing a network mangement app for my company and decided to go with tomcat/java. So
I am a bit
rusty on the nitty-gritty of the app server setup.
First, here is my server.xml (sorry long)

RE: comparison of Type 4 JDBC drivers
Thanks Yoav for the suggestion! Can anyone point me to a comparison of Type 4 JDBC drivers supporting MS SQL Server and DB2 for the windows and IBM mainframe (Z_OS) linux platforms? thanks...gary... -Original Message- From: Shapira, Yoav [mailto:[EMAIL PROTECTED] Sent: Thursday, March 18, 2004 6:02 AM To: Tomcat Users List Subject: RE: Tomcat 4.1.12LE Disappears Hi, Any and all suggestions will be welcome? ;) OK. Drop the JdbcOdbc bridge so fast you do it even before the end of this sentence. Use a thin/type4 JDBC driver for your database. What's happening is that your JdbcOdbc bridge driver is crashing with a native-level (i.e. some DLL on Windoze) error. That's crashing the JVM internally, hence the hs_err_pid logs. (HS stands for HotSpot). After tomcat crashes the ISAPI connector can't connect to it, hence the jk errors in your log: these will go away if you fix your tomcat.

mssqlserver jdbc drivers - memory leaks
This is more of an informative e-mail than a problem. I was using the mssqlserver jdbc drivers on both Solaris and Linux platforms. The web application is using lots of @@Identity and inserts into the database. There was an instance to test some stuff that I was attempting lots of inserts ( more than 10,000 ). When attempting to do some logging I got a (Too may open files) exception. Well I changed out the mssqlserver jdbc to an existing JTurbo jdbc license we had and the problem went away. So needless to say there are memory leaks in the microsoft jdbc drivers. I was pulling my hair out over this and I was hoping to spare anybody anguish if possible.

JDBC Drivers Exception ...
Hi:
I am using Apache 1.3.26 + JBoss + Tomcat on my Web/APP Server and Oracle
9.1 on DB Server.
I installed JDBC Drivers ojdbc14.jar, classes12.jar, nls_charset111.jar on
my APPLICATION Server and SET the CLASSPATH accordingly.
What all need to be done as far as this is concerned?
When I run my Simple Web Applicatin which Access my DB Server: I get
Exception at following Line:
--
try
{
Class.forName(oracle.jdbc.OracleDriver);
con = DriverManager.getConnection(url,user,pass);
stmt = con.createStatement();
}
catch (Exception e)
{ System.out.println(Exceptino raised at Clas.forname.); }
--
Can anyone TELL what is this error about?
Also, my APP SERVER has just moved to JDK1.4 whereas my DB Server still has
JDK 1.3. Do you think this is an issues?
Thanks!

Why both ojdbc14.jar and classes12.jar? If you're connecting to an
Oracle 9.1 database, you don't want classes12.jar in there. These two
jars have some overlapping classnames which will cause problems.

Tomcat ignores the CLASSPATH environment variable. You need to make

is inside the /WEB-INF/lib directory of your web application OR the

Which line generates the exception? All three lines above, not to

Also, what is the exception? You didn't give details. Please give the
full stack trace and message for the exception.
In addition, I thought the Oracle docs said to use
oracle.jdbc.driver.OracleDriver to load the driver, not the shorter
oracle.jdbc.OracleDriver. Check the Oracle JDBC driver docs on that.
Also, my APP SERVER has just moved to JDK1.4 whereas my DB Server still

Probably not an issue. But then again, I haven't even seen your stack

Should be using nls_charset12.jar, if you're using classes12.jar. If you're
to use the version 12 drivers, then you ought to include ocrs12.jar as well.

Date: Wed, 19 Feb 2003 15:17:48 -0500
Howdy,
A few things.
I installed JDBC Drivers ojdbc14.jar, classes12.jar, nls_charset111.jar
on
Why both ojdbc14.jar and classes12.jar? If you're connecting to an
Oracle 9.1 database, you don't want classes12.jar in there. These two
jars have some overlapping classnames which will cause problems.
my APPLICATION Server and SET the CLASSPATH accordingly.
Tomcat ignores the CLASSPATH environment variable. You need to make
sure the JDBC driver distribution is in the proper place. Usually, this
is inside the /WEB-INF/lib directory of your web application OR the
common/lib (or equivalent) directory on the server.
When I run my Simple Web Applicatin which Access my DB Server: I get
Exception at following Line:
---
---
try
{
Class.forName(oracle.jdbc.OracleDriver);
con = DriverManager.getConnection(url,user,pass);
stmt = con.createStatement();
}
catch (Exception e)
{ System.out.println(Exceptino raised at Clas.forname.); }
---
---
Which line generates the exception? All three lines above, not to
mention you ..., can generate exceptions. Break up the code
into multiple try-catch blocks.
Also, what is the exception? You didn't give details. Please give the
full stack trace and message for the exception.
In addition, I thought the Oracle docs said to use
oracle.jdbc.driver.OracleDriver to load the driver, not the shorter
oracle.jdbc.OracleDriver. Check the Oracle JDBC driver docs on that.
Also, my APP SERVER has just moved to JDK1.4 whereas my DB Server still
has
JDK 1.3. Do you think this is an issues?
Probably not an issue. But then again, I haven't even seen your stack
trace yet.

Re: using DataSource with Microsoft's JDBC drivers
Excellent. This worked for me. Thanks! Several of the parameters were different than expected, and I think it was the driverName parameter that was the key. I recommend that this set-up example get added to http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html, to thus provide an example for MS SQLServer access.

using DataSource with Microsoft's JDBC drivers
I've anyone's successfully configured Tomcat to use Microsoft's JDBC driver package (i.e., com.microsoft.jdbcx.sqlserver) as a Tomcat Resource, for creating connections via DataSource, I'd love to hear from you. I've gotten their driver to work via the DriverManager path, but via a DataSource am having no luck.Intead of repeating all what I've tried, I'd just like to know if anyone's got the driver to work well with Tomcat, and a bit about their environment.

Classloaders, JDBC drivers (etc.), and reloading webapps with the /manager
Hello, If I include a JAR file for a JDBC driver within my webapp's /WEB-INF/lib path, calling Class.forName(some.driver) registers the driver with the java.sql DriverManager. No problem... until I reload the context using the /manager webapp. Is the class definition (and in particular, the driver instance) still valid, given that the classloader used for the driver (and all classes loaded by it, including the driver) will have been reloaded ?

RE: Classloaders, JDBC drivers (etc.), and reloading webapps with the /manager
if your driver is a pure java driver(type 4, I think) then you would be ok. If your driver uses native libraries for its java implementation, then you will have a problem. you want to put the jar in your /common/lib so that it is is loaded once and shared for all contexts that need it. This way a reload will not affect it.

JAR = Zip + restrictions on the structure. It turns out that Oracle was kind enough to include the correct structure so all you need to do is rename the .zip to .jar.

Where to place JDBC drivers? How?
I found some JDBC drivers for accesing an IBM AS400 But I can't get them to work within the browser environment. I placed an entry in my system variables Name: CLASSPATH Value: loacation of JDBC.jar file;location of JDBC license.jar (in windows is CLASSPATH = Path???) The Drivers came with a few applets; with the correct information these applets will connect to my as400 db but with the same info my jsp pages won't connect, I keep getting errors that look like this A Servlet Exception Has Occurred Exception Report: javax.servlet.ServletException: hit.as400.As400Driver Root Cause: java.lang.ClassNotFoundException: hit.as400.As400Driver Where should these jar files be placed? Do they need to be within the webapp tree? DO I need to reference their location in the server.xml file?? Should they be placed within the JDK tree???

You need to make sure you put a reference to the driver location in your class_path variable.

RE: Where to place JDBC drivers? How?
There are variations between versions of Tomcat on how things work. For instance, Tomcat 3.2 recognized things in the classpath whereas Tomcat 3.3 doesn't. 3.3 has directories in its installation where jars can be added globally. I don't know how 4.x handles it. To be safe, I think WEB-INF/lib is the recommended and most universal place to put jar files for your web application.

RE: Where to place JDBC drivers? How?
It needs to be in the Classpath variable so that the jar file can be found. You can add it to the WEB-INF folder but then you will have to put a copy of the driver in the WEB-INF folder of every application that should be able to access the database. As for the other files it depends whether you're running Tomcat as a service under NT or not etc. There is a classpath variable that is passed to java in each of these files. The files are simple to edit, just open them up and have a look. -Original Message- From: Mike Kelley [mailto:[EMAIL PROTECTED]] Sent: Wednesday, November 28, 2001 7:09 PM To: 'Tomcat Users List' Subject: RE: Where to place JDBC drivers?

Re: Where to place JDBC drivers? How? SOLUTION FOUND!
If you have only one web-app that references this driver, you should put it in WEB-INF/lib. This allows for better maintenance and management of your libraries and dependencies. To reference/load the driver classname, you could use a parameter entry in the web.xml file... You could even have a startup servlet to load the driver in DriverManager and/or have it available through some lookup system such as a JNDI service. I think this is cleaner than having it in Tomcat/common/lib UNLESS you want those drivers to be available for all web-apps you create. - Original Message - From: Mike Kelley [EMAIL PROTECTED] To: 'Tomcat Users List' [EMAIL PROTECTED] Sent: Wednesday, November 28, 2001 02:02 PM Subject: RE: Where to place JDBC drivers?

I don't know why Oracle still names those files .zip, but it doesn't hurt anything to rename them to .jar.

JDBC drivers for SQL server
I am looking for goodcheap (free if possible) JDBC drivers for SQL server. Randy, you told me inetsoftware.de make good drivers. Maybe we will opt for this cie but their prices range from USD 200 to 400... Its expensive for mere drivers (are JDBC drivers so difficult to develop?) And i was wondering if there isn't any JDBC drivers supplied with SQL server. If so, we wouldn't have to pay third-party cie, the migration to servlet would be cheaper, and my boss, happier. If not, what other (cheaper or free if possible) alternatives do i have? Thx alex

We're using freetds (http://www.freetds.org) which is an open source JDBC driver for SQL Server. We've been running with it for a month and only had one problem (jdbc realm wasn't working) that got cleared up by some supportive folks on their mailing list.

There is nothing in tomcat.log. I've opened the driver jar file, and the
TdsDriver class is definitely in there, and I get the same error whether I put
the jar in TOMCAT_HOME/lib or in WEB-INF/lib or in WEB-INF/classes. I've even
tried adding it to my CLASSPATH and rebooting.
I wrote a little java console program to test the driver and it works fine by
running it with the -classpath option.
Thanks for any suggestions.
