Torque using Tomcat
I'm using Torque 3.1.1 with Tomcat 5.0.28 and MySQL. In a Tomcat context.xml file I've defined a JNDI DataSource and in torque.prorperties the JndiDataSourceFactory factory is being used. The webapp works fine until the webapp is realoaded. The first database access after a reload gives this stack trace: Caused by: java.lang.NullPointerException: There was no DataSourceFactory configured for the connection my_om at org.apache.torque.TorqueInstance.getConnection(TorqueInstance.java:711) at org.apache.torque.Torque.getConnection(Torque.java:268) at org.apache.torque.util.Transaction.beginOptional(Transaction.java:80) at org.apache.torque.util.BasePeer.doSelect(BasePeer.java:1195) Any ideas?

Torque using Tomcat
Hello,
I've tried to use Torque within the Servlet but I receive always a
ClassNotFound-Exception.
Maybe somebody could solve the Problem:

I looked through the list archives (in a Eudora folder) very carefully (back to Oct 2002, when I started lurking) and found may issues involving the same error message, but most of them involved configuration issues. (Everything works for me unless I reload the webapp.) Didn't find anything other than the NullPointerException (java.lang.NullPointerException: There was no DataSourceFactory configured for the connection my_om) in the logs, either. I had originally defined the DataSource in the Tomcat . Last night I tried in the section and got the same error. I'll try to put together a simplified test case if you think that it is worthwhile.

Re: Torque using Tomcat
Hi all, I got the same problem too. I deployed my app in JBoss with Tomcat. Torque is being used in my Session Bean. Each time I redeploy the app, Torque will fail. Then, instead of just redeploying the app, I have to restart JBoss all over again. Haven't got any clue either. I've been searching for the solution but I can't find any. Could anybody in the list give me some idea? Thanks. On Thu, 16 Dec 2004 12:24:10 -0800, "M. Sean Gilligan" <[EMAIL PROTECTED]> said: > >"M.

Your container probably tries to save the existing session on a restart (because reloading your webapp is nothing but a restart of your application) and falls over its feets. When it comes up again, its session information is incomplete and you get strange errors. Try the following thing. I assume now, that you use Tomcat5: - open your tomcat/conf/server.xml file - look for the element for your application. - if you don't have one, you must create one. The result should look like this: Important is the 'pathname=""' Stop Tomcat. Nuke the contents of the work/ and the temp/ directory. Start again. See if the problem vanishes. If yes, you have a serialization issue with Torque.

To be clear: the problem is fixed by a restart of Tomcat and only occurs when you reload the webapp after it has been loaded once. I followed your instructions (which included a restart of Tomcat) tried to login once and it worked, the restarted the webapp and tried to login again and got the same stack trace. One variation from your procedure is that I'm not editing server.xml but specifying a Context.xml in the Tomcat ANT task. The version I just tested is like this: url jdbc:mysql://localhost/mysqldb username xxx password xxx driverClassName org.gjt.mm.mysql.Driver maxWait 5000 maxActive 4 maxIdle 2 url jdbc:postgresql: pgdb username xxx password xxx driverClassName org.postgresql.Driver maxWait 5000 maxActive 4 maxIdle 2 Any further information and/or suggestions would be greatly appreciated.

Re: Torque using Tomcat
Hi, I can confirm the behaviour Sean's having. I've been seeing it since we upgraded to torque 3.1.1. which uses commons-configuration-1.0. I think what happens is that when torque initialises it tries to find your datasource through JNDI which you have configured in Torque.properties, and after it also tries to initialise a datasource and bind it to your context which you actually have not configured in your properties file. Previously the commons-configuration package would give a null object when no subconfiguration for the datasource was found in the properties file, but since 1.0 it returns an empty subconfiguration object (which is not null), and that is what 'breaks' the code. The second time you load your app this causes an NameAlreadyBoundException, causing torque initialisation to fail. Ive recompiled torque source with a small patch in the JndiDataSourceFactory and this solves the problem. Recompiling Torque 3.1.1 with and older version of commons-configuration also does the trick. I have also found an elaborate post on the same problem in the archives: http://nagoya.apache.org/eyebrowse/ReadMsg?listName=torque- [EMAIL PROTECTED]&msgId=1440765 Hope this helps, Grtz Wieger On Wed, 2004-12-22 at 18:30 -0800, M.

Re: Torque using Tomcat
Hi, Do you think your change in JndiDataSourceFactory is general enough to be included in future releases of Torque ? If yes, can you please open a ticket in Scarab http://nagoya.apache.org/scarab/issues open a bug report and attach your patch ?

I'm not sure if he used the exact same patch as in this message:
http://nagoya.apache.org/eyebrowse/[EMAIL PROTECTED]&msgId=1440765
but, I put the patch into my local CVS tree and cleaned up the code

I plan on trying out a build tomorrow. My CVS tree has the latest code, but I
should probably build a patched version based on the TORQUE_3_1_1 tag if I want
to put this into "production", right?

There have been sone largish changes in the 3.1 branch since the 3.1.1 release, and though I believe personally that the current state of the TORQUE_3_1_BRANCH in CVS is ok except for one small template, these changes have not yet been widely tested and therefore it should be safer for you to patch the release. No need to use CVS though, there is also a source package for 3.1.1 available ;-) Please tell us if the patch worked for you, so it can be changed in CVS too.

If you want to use JndiDataSourceFactory from the 3.1.1 tree, you also need the AbstractDataSourceFactory class and probably the other DataSourceFactories from the 3.1.1 tree. Maybe there are other dependencies in there, but I do not know the code well enough to tell without trying. If patching the 3.1.1 file with the change you found in the mail archives works, this should be fine.

Re: Torque using Tomcat
Hi, This is a late reply to this Tomcat problem. But I have no problems using Torque 3.1 (or 3.1.1 not sure) with Tomcat 4.x. The main application in which I do development is a jar file when it is started in Tomcat. If I make some changes, to the java files, I recompile and create a jar file and simply overwrite the jar file that Tomcat is using. When I do this, within a span of 10 secs, Tomcat realizes that the jar file has changed and restarts itself. Torque is reinitialized and everything works without a problem except the fact that the session before the restart is no more there. I don't need the session to exist between restarts, so it's not an issue for me. I can give more details on how I configure this if anyone is interested. Btw, yes I use a JNDI datasource that is provided by Tomcat. Thanks, Sarav On Thu, 2004-12-30 at 08:33 +, Henning P. Schmiedehausen wrote: > "M.

Re: Torque using Tomcat
I have exactly the same issue, that the session does not persist over a restart, except that I am *not* using JNDI. >From the Tomcat logs I can see that there is a serialisation issue associated with the application restart. The sessions used to persist but some changes in the application have caused it not longer to do so. Therefore, for me at least, I am fairly sure that this is an application issue and not a Torque/Struts/Tomcat issue.

Re: Torque using Tomcat
Hi, I think the problem can be with your:
import org.apache.torque.Bank
where Bank is a generated class by Torque, so I doubt it has been
generated in the org.apache.torque package.

Re: Torque using Tomcat
We explicitly laod the properties file and pass the Configuration into
Torque.init
by using PropertiesConfiguration files. See Apache commons Configuration.
I sure there's more details of how to load and debug the file loading there.
It's most likely looking in your current directory.

Re: Torque using Tomcat
Try initializing Torque with an absolute path. To get the absolute path,
you can prepend the webroot directory to your relative path. You can get
the webroot directory from the servlet container, e.g.
String webroot;
{
// always use slashes, no backslashes
webroot =
config.getServletContext().getRealPath("/").replace('\\','/');
// Make sure path ends with a slash
if (!webroot.endsWith("/"))
{
webroot = webroot + "/";
}
}

Re: Torque using Tomcat
No, sorry! It's still not working!
Maybe somebody can give me short HowTo! It doesn't have to be this example.

RE: Torque using Tomcat
Ok, lets start back at the beginning. You say you're getting a
ClassNotFound Exception. Exactly what is the text of the error
you are getting, including all the Stacktrace info? It's most
likely in one of the Tomcat logs.
Do you have ALL the Torque Runtime required jar files (not just
torque*.jar) in a Tomcat library? E.g., in the WEB-INF/lib or
shared/lib directories?
Another possible "class not found" cause is that your JDBC driver
class name is mistyped in the Torque.properties or that it's jar
file is not in one of the Tomcat libraries.

Re: Torque using Tomcat
Shouldn't your classes be in WEB-INF/classes not WEB-INF/src? Joe On 23/06/06, Norbert Kunstek <[EMAIL PROTECTED]> wrote: Hello, I have all the required jar-files in the WEB-INF/lib directory (torque runtime + dbdriver). My Torque.properties is in the WEB-INF directory. I have the HelloServlet + the bank-classes in the WEB-INF/src directory.
RE: Torque using Tomcat
Hmm, the full error message indicates that something is really strange in your Generated Torque classes. Your Bank class looks like it was generated in the persistance package but it's trying to call org.apache.torque.map.BankMapBuilder. The BankMapBuilder class is a generated class that should be under the persistance package (default would be persistance.map) In a previous message, it seemed like you generated your classes into the org.apache.torque package. Do you still have code from this bad package choice hanging around? I suggest you go back the Torque class generation step; clear out all the generated java files in the org.apache.torque and persistent directories (and sub directories); make sure your schema file has a new date on it; and regenerate/re-compile everything. Then use ALL the classes / packages under the persistance directory in your web app. > -Original Message- > From: Norbert Kunstek [mailto:[EMAIL PROTECTED] > Sent: Friday, June 23, 2006 11:32 AM > To: Apache Torque Users List > Subject: RE: Torque using Tomcat > > > 23.06.2006 17:24:03 org.apache.torque.util.BasePeer getMapBuilder > SCHWERWIEGEND: BasePeer.MapBuilder failed trying to > instantiate: org.apache.torque.map.BankMapBuilder > java.lang.ClassNotFoundException: org.apache.torque.map.BankMapBuilder > at > org.apache.catalina.loader.WebappClassLoader.loadClass(WebappC > lassLoader.java:1340) > at > org.apache.catalina.loader.WebappClassLoader.loadClass(WebappC > lassLoader.java:1189) > at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:302) > at java.lang.Class.forName0(Native Method) > at java.lang.Class.forName(Class.java:141) > at > org.apache.torque.util.BasePeer.getMapBuilder(BasePeer.java:1355) > at persistence.BaseBankPeer.(BaseBankPeer.java:78) > at persistence.BaseBank.(BaseBank.java:40) > at HelloServlet.doGet(HelloServlet.java:42) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:689) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) > at > org.apache.catalina.core.ApplicationFilterChain.internalDoFilt > er(ApplicationFilterChain.java:252) > at > org.apache.catalina.core.ApplicationFilterChain.doFilter(Appli > cationFilterChain.java:173) > at > org.apache.catalina.core.StandardWrapperValve.invoke(StandardW > rapperValve.java:214) > at > org.apache.catalina.core.StandardValveContext.invokeNext(Stand > ardValveContext.java:104) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipel > ine.java:520) > at > org.apache.catalina.core.StandardContextValve.invokeInternal(S > tandardContextValve.java:198) > at > org.apache.catalina.core.StandardContextValve.invoke(StandardC > ontextValve.java:152) > at > org.apache.catalina.core.StandardValveContext.invokeNext(Stand > ardValveContext.java:104) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipel > ine.java:520) > at > org.apache.catalina.core.StandardHostValve.invoke(StandardHost > Valve.java:137) > at > org.apache.catalina.core.StandardValveContext.invokeNext(Stand > ardValveContext.java:104) > at > org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReport > Valve.java:118) > at > org.apache.catalina.core.StandardValveContext.invokeNext(Stand > ardValveContext.java:102) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipel > ine.java:520) > at > org.apache.catalina.core.StandardEngineValve.invoke(StandardEn > gineValve.java:109) > at > org.apache.catalina.core.StandardValveContext.invokeNext(Stand > ardValveContext.java:104) > at > org.apache.catalina.core.StandardPipeline.invoke(StandardPipel > ine.java:520) > at > org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:929) > at > org.apache.coyote.tomcat5.CoyoteAdapter.service(CoyoteAdapter. > java:160) > at > org.apache.coyote.http11.Http11Processor.process(Http11Process > or.java:799) > at > org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandle r.processConnection(Http11Protocol.java:705) > at > org.apache.tomcat.util.net.TcpWorkerThread.runIt(PoolTcpEndpoi > nt.java:577) > at > org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run( > ThreadPool.java:684) > at java.lang.Thread.run(Thread.java:534) > 23.06.2006 17:24:03 persistence.BaseBankPeer > SCHWERWIEGEND: Could not initialize Peer > org.apache.torque.TorqueException: > java.lang.ClassNotFoundException: org.apache.torque.map.BankMapBuilder > at > or
