Re: get the SQL to be executed
You can use a logging driver such as p6spy to see your SQL statements. http://sourceforge.net/projects/p6spy/ On 19 January 2012 08:25, Thomas Fox thomas@seitenbau.net wrote: Perhaps you can use the log output (with some tweaks to the log4j configuration). However I'm not sure how and if Torque 3.3 logs the update statements. But then again I've heard of drivers which at as a bridge between the application and the real driver (e.g http://www.squirrelsql.org/) and which can do the logging for you. Torque 4 will not work because it uses prepared statements for updates, this will not give you any sensible sql. Thomas Hello all, is there a way in Torque to get the SQL that is sent to the DB. I have to generate a txt file where I save queries basically INSERT statements of long records. I was thinking of create the Torque classes, populate the objects with data that I get from a local instance of the DB and then, instead of using a save command, get the SQL that would be executed and store it in a file. Alternatively I could use this: http://openhms.sourceforge.net/sqlbuilder/ but has dependencies that requires GPL license and I would avoid in this case that kind of license. - To unsubscribe, e-mail: torque-user-unsubscr...@db.apache.org For additional commands, e-mail: torque-user-h...@db.apache.org - To unsubscribe, e-mail: torque-user-unsubscr...@db.apache.org For additional commands, e-mail: torque-user-h...@db.apache.org

Re: java.lang.OutOfMemoryError
For the latest versions of 1.4.2 (_10 and up) and 5/6 there is a very useful utility called jmap - http://java.sun.com/j2se/1.5.0/docs/tooldocs/share/jmap.html that's built into the Java SDK. This dumps out all the objects in the heap. Doesn't work under windows though.. Joe On 30/12/06, Thomas Fischer [EMAIL PROTECTED] wrote: An out of memory error is typically very difficult to pinpoint. The place where this error occurs is typically not connected to the place where the problem sits. Personally, I know of two ways of dealing with this - you can have an idea what happens. The answers before have provided situations where OutOfMemory-Problems typically happen. - If you think that none of the typical causes apply to you, you have to find out the hard way. To get an idea of the cause of the problem, create a heap dump of the virtual machine just after an OutOfMemory-Error occured (on linux, this is done by using the kill -3 command on the appropriate process). Then, scan through the heap dump to see which objects occur most often. These are usually the objects which are not dereferenced and cause the memory overflow. Then go through the code and find out where these objects are created, and why they are not thrown away after being used. You might need more information out of the heap dump than just the class names of the relevant object; there are tools showing the refences out of heap dumps but I never used one myself.

Re: Torque plugin for Eclipse
I can confirm that the ant scripts work fine in Eclipse. Don't forget the build.properties though - which eclipse does confuse with plugins but just click the plain text edit or use a different name in the ant build file. Remember to press F5 (refresh) after a generate too! :-) We use WTP 1.5 and it has good XML validation/editting. Joe On 17/10/06, Greg Monroe [EMAIL PROTECTED] wrote: There is not a specific Torque plug-in but since it's Maven and Ant driven, it works fine in this environment. There is a Maven plug-in for Eclipse that can run the generator, see www.mevenide.codehaus.org. FYI, Torque still works best with Maven 1.x, 2.x support is still rudimentary. FWIW, I use ant build files for my projects and these work well in Eclipse. For editing Schema files, there is a lot of Eclipse XML options out there. I use Eclipse with the MyEclipse addin and this does a decent job of handling XML validation, etc. One thing to remember is that Torque is not like a lot of other OM layers. It requires very little bookwork (unlike that H.. word one 8) ) and hence IMHO no specific plugin is needed. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 17, 2006 8:05 AM To: Apache Torque Users List Subject: Torque plugin for Eclipse Hi.

Re: Configuring encoding that is used for jdbc connection
Certainly for Sybase it's set via the database itself. It's independent of Torque. We moved to UTF-8 to avoid charset issues.

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.

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: No search for mailing list archives ??
The alternative is to use a JDBC driver like p6spy. This puts itself between Torque and the real driver. Has the advantage of getting any JDBC written by hand too. Works very well - but don't use it on a production server as it leaks like a sieve!
