Tomcat5w GUI application
I have been using Tomcat5w GUI application since some time and today i hit an
issue with adding a new jar to the classpath.
The change i made was It was not getting saved.
I counted the characters and found out it was 1024, is this the max i can set ?
How do i set if i have to go above this limit.
Thanks
Venkat

Microsoft does call it as a type 4 driver, i am not sure though why there are
some dll files in the installation folder.
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=99b21b65-e98f-4a61-b811-19912601fdc9
Placing only sqljdbc.jar file under CATALINA_BASE/common worked.
I need to confirm why dll files, so my change does not impact anything.
Again any insight is appreciated while i try looking for some information on
Microsoft website.

Yes we use connection pooling mechanism
I will try placing these in CATALINA_BASE/common
:-) yes we use Microsoft SQL Server JDBC 2.0 , let me search for pure java
drivers, you have any pointers.

If you are using Tomcat's connection-pooling mechanism, you'll need to
place your JDBC library any any supporting libraries (such as native
libs) under CATALINA_BASE/common and take care NOT to put them into your
webapp's WEB-INF/lib directory. That's an unfortunate requirement of
Tomcat's connection pooling mechanism.
If you are NOT using Tomcat's connection-pooling, then you should put
all those libraries into your webapp's WEB-INF/lib directory.
Tomcat basically builds all "class paths" (that is, locations where
libraries are located, not to be confused with the actual CLASSPATH
environment variable which you should pretty much never use) in a smart,
safe, and sane way. You should just follow the rules and everything
should be okay. Those rules are, roughly:
1. Don't set the CLASSPATH environment variable and/or
Don't change the CLASSPATH setting in the service configuration
2. Put all the libraries your webapp needs into the webapp's WEB-INF/lib
directory
That's basically it. The fact that your webapp uses some particular JDBC
driver is technically irrelevant: the server should provide a JDBC
DataSource to your webapp and the server should configure it. That's why
the server needs to have access to the JDBC library itself instead of it
being stuck in your webapp's WEB-INF/lib directory.
By the way, yuck: whose JDBC library requires a native library these
days? Is that Microsoft SQL Server. I thought they had a pure-Java driver.

Thank you this worked.
However another question, i have jdbc drivers in the classpath, i tired
copying whole folder under WEB-INF it was not picked up.
i did not try copying the sqljdbc.jar right under web-inf as i am not very sure
of how other file like .dll get used.
any insight would help.
Regards
Venkat

No, it should contain just the values when you installed the service; something
like:
C:\Apache-tomcat-5.5.23\bin\bootstrap.jar
> All my jars on \Apache-tomcat-5.5.23\webapps\WebProxy\lib,

That's an inappropriate location; any jars specific to a webapp should be in the
webapp's WEB-INF/lib directory, not some arbitrary location. Read the servlet
spec.

Thanks for the link, i will have to try this late evening today when users log
off
Couple of questions
1. So i leave classpath blank on the GUI on the Java tab ?
2. All my jars on \Apache-tomcat-5.5.23\webapps\WebProxy\lib, not sure if it
will still pull based on the list i see
************
Therefore, from the perspective of a web application, class or resource loading
looks in the following repositories, in this order:
* Bootstrap classes of your JVM
* System class loader classes (described above)
* /WEB-INF/classes of your web application
* /WEB-INF/lib/*.jar of your web application
* $CATALINA_HOME/common/classes
* $CATALINA_HOME/common/endorsed/*.jar
* $CATALINA_HOME/common/i18n/*.jar
* $CATALINA_HOME/common/lib/*.jar
* $CATALINA_BASE/shared/classes
* $CATALINA_BASE/shared/lib/*.jar ******************

You really should not be adding anything to Tomcat's classpath. Put your jars
in an appropriate location, and let the built-in classloaders find them.
