Database Pooling Follow-up
Hello,
I want to say thanks for the links yesterday in regards to my pooling problem.
After reading the docs, I have a better handle on how this will work.
I am ready to test, and I was able to get the following to work within a JSP
page.
But I would really like to create a Singleton class that could hand out
connections based upon something like: singleton.getHandle(jndiname); So in
my business object I can hand in a name and let the busines object get the
connection, etc.
Does that make sense. Only problem is, I cannot figure out how to transfer the
JSP snippet below, to physical java code.
Anyone know?
Thanks,
Scott

Re: Database Pooling Follow-up
I have a method call I think probably does what you want
public static Connection getPooledConection(String JNDIName) {
Connection con = null;
DataSource ds = null;
try {
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup(java:comp/env);
ds = (DataSource) envCtx.lookup(jdbc/+JNDIName);
con = ds.getConnection();
}
catch(Exception e){
System.out.println(new java.util.Date()+ Blah Blah Blah\n+
Conection was forced closed!\n+
JNDIName : +JNDIName+\n+e+\n+e.getMessage()+\n\n+
e.printStackTrace() );
try { con.close(); } catch(Exception d) { }
} // Close exception catch
return con;
} // Close method

Database Pooling
Hello, To start off with, I hand rolled a database pooling class to handle database pooling for a ecommerce site I am writing. The application is web-based so of course I am using Tomcat 5.5 and all was going well. But in my implementation, I occasionally get errors when the connection has not been used for a long period of time. Basically mysql or tomcat may be taking themselves out of service and I get some java.net errors through Tomcat. Anyway, I got frustrated and began to look through some on-line docs in regards to Tomcat and DatabasePooling. Which leads me to my question: Is pooling build-in to Tomcat 5.5? If so, how simple is this to implement (I have read here: http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-resources-howto.html but I an not familiar with JNDI. And if it does it take care of shutting down the pool when the server gets reloaded or gets unloaded? Currently my pooling solution is huge, with threads to monitor if they are closed, etc. I figure there has to be a better implementation, or solution for myself in this regards Could anyone please help out with some sample, or explanation of how this all fits together. I have created business objects, so I just need to call the database from business objects, not directly from tomcat.

Re: Database Pooling
MySQL shuts down the connections after 8 hours. Ran into this myself. Yes, Tomcat has pooling built in. Yes, it handles all aspects of the pool. Try this link to start with: http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jndi-datasource-examples-howto.html It is directed more to the database pooling. There is also lots of entries in the archives. Some people have no problem setting it up but there are a few that run into some configuration issues that seem to baffle them. Some tips: Watch the naming that both case and spelling match. Put the drivers in common/lib Use the latest drivers. Make sure you have only one copy of the drivers.

RE: Database Pooling
application-server-managed database pools are great, they take all the work out of writing your own pooling implementation, and are normally better at it too. furthermore you get to label the pool in a generic way so that your application only needs to acquire the JNDI context and pluck out the datasource (which returns connections). the way in which database pools are setup inside the application server will be app-server specific, but the major players out there (bea, jboss, tomcat) all have the ability to do so. it's a no-brainer for j2ee web applications of yuor mid-sized nature I think. -Original Message- From: Scott Purcell [mailto:[EMAIL PROTECTED] Sent: 16 November 2004 21:35 To: [EMAIL PROTECTED] Subject: Database Pooling I am developing a mid-sized application, which will use JSP Model 2 Architecture.

JDBC pooling is pretty standard in containers these days, Tomcat included. ;) The code side of this picture is pretty portable: look up a DataSource via JNDI, use that to fetch connections. The configuration side is container-specific. Tomcat has excellent docs on this at the website. If inter-container portability is a great concern (e.g. you sell your app to external clients), you could also manage the pool yourself using the commons-dbcp package. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Tomcat 4.1 not starting, how do I track error (database pooling)
Hi having written an application that ran fine on Tomcat 5 I am having to regress it to run on Tomcat 4.1 running on Windows. part of the deployment involves setting up database pooling. First of all I deployed my application war only and started Tomcat using catalina start this worked ok, but I then needed to configure database pooling to get it fully working. In Tomcat 5.0 I had a config file /contextname.xml /under CATLINA_HOME/conf/catalina/localhost which worked fine, under Tomcat 4.0 I have added the contents to server.xml. I then ran catalina.bat start this starts another window but then disappears immediately before I am able to trap the problem, there is nothing in the log file to indicate the problem. Could anybody please help with any of the following ? 1. How do I stop the window started my Catalina from disappearing so I can see what the problem is. 2. In Tomcat 4.0 can I have a config file for my application rather than adding it to server.xml 3. I am using the mysqllConnectector 3.15 driver does this work with Tomcat 4.0. 4. Are pooling connections configured the same in 4 as 5 or not below I have listed the contents of my xml file from Tomcat 5.

Hi, 1. How do I stop the window started my Catalina from disappearing so I can see what the problem is. Use catalina.bat run instead of startup.bat (which calls catalina.bat start). 2. In Tomcat 4.0 can I have a config file for my application rather than adding it to server.xml No. 3. I am using the mysqllConnectector 3.15 driver does this work with Tomcat 4.0. Yes. 4.

Thanks very much all working, the problem was I had removed docbase paramter not hinking it was needed because the code was hosted directly under webapps. BTW username is correct in TC4. My context is privileged just because I copied it from somehwere else without knowing what it meant, no good reason. Shapira, Yoav wrote: Hi, 1.

Help Database Pooling in Linux
Hi I am experiencing a bit of a tricky problem. I have an application developed under windows. The application talks to a MySQL database using connection pooling. The application works great hosted on Tomcat under Windows, but when it is placed on Linux the application cannot establish a connection to the database. Previously it has been able to connect under linux and no change has been made to the connection pool classes. I have checked that the database can be reached from the Linux server and it can, and I can connect to the database if I use a direct JSP database call. But the application will not establish a connection either to a local database or to a database hosted on another machine. I have tried pretty much everything I can think of and am now out of ideas so any ideas/pointers would be gratefully received.

Connection/Database pooling
Hi, I was wondering if someone can give me a little advice. I am currently using Apache webserver, Tomcatserver, and an Oracle database. I have created a wireless app using JSPs/WML. Basically I was wondering how best to architect it to take full advantage of Tomcats connection and database pooling? Should I be using servlets versus JSPs? Sorry if this is a dumb question. Thanks for your help in advance!
Re: Connection/Database pooling
Not a dumb question at all: DB connection pooling is not intrinsic to Tomcat, but must be grafted on using a 3rd-party library (there are many). None of these will prevent you from using JSP; the connection pool looks exactly like a normal JDBC connection. You may want to browse through the docs for Jakarta-Turbine as an alternative application environment that sits on top of Tomcat and provides many services, including db connection pools. -- Gary Lawrence Murphy [EMAIL PROTECTED] TeleDynamics Communications Inc Business Innovations Through Open Source Systems: http://www.teledyn.com Computers are useless.
