I would still rethink using a technology that violates the J2EE by requriing access to the file sytem in order to work properly. Just a claryfing note: Velocity is not intended to be exclusively used within a ServletContainer, it can be used in any java application. So, it comes with a FileResourceLoader, a JarResourceLoader and a ClasspathResourceLoader (recommended to be used with Tomcat). Owen: Why don't you try your hand at changing your velocity configuration in velocity.properties to use one of the other loaders with a packed war? http://jakarta.apache.org/velocity/developer-guide.html --- Julio César Aguilar Cabrera [EMAIL PROTECTED] Proyecto SIGC3, LANIA - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: shared/lib again...
Sorry about not being clear enough last time. Let's see... The original problem was with a Filter, which was started at deployment. Then to my opinion this is due to Filter initialization (not run-time usage) as implemented in Tomcat. That was my first thought when you brought up the question about the moment of the CNFE happening but I tried with classes needed at runtime (Velocity classes, for example) and could not find those either. Using my code or your servlet. Stop, now I've messed up. :-) Your code can not find some jars in question, but mine does?? No. Your code does not find things if I put in my application. But it does find classes in jars in shared/lib within a test (almost empty) application living in CATALINA_HOME/webapps. I know it does not seem important but I have no other clues by now. --- Julio César Aguilar Cabrera [EMAIL PROTECTED] Proyecto SIGC3, LANIA - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: shared/lib again...
I've done several tests in Windows and this is what I found. To remember my settings No CATALINA_BASE defined. Tests done with CATALINA_HOME/shared/lib. 1. As being told, I can find jars put in CATALINA_HOME/common/lib. 2. What exactly the moment when CNFE is thrown? You said that the applications is not even start due to CNFE, so that classes are needed during deployment or while normal application functioning? The original problem was with a Filter, which was started at deployment. If I place the jar that contains the Filter class in WEB-INF/lib then the application starts, but looking for classes needed after deployment (during a normal run) I can't find them if the corresponding jars are in shared/lib. 3. Something I had not mentioned about my application (I did not thought it was relevant) is that it lives outside the CATALINA_HOME directory, is referred to by a context.xml file in CATALINA_HOME/conf/Catalina/localhost. Using a test application in CATALINA_HOME/webapps and compiling the IsThereThisClass servlet provided by Veniamin I can finally find the classes within shared/lib. So, could this be the cause of my problem? --- Julio César Aguilar Cabrera [EMAIL PROTECTED] Proyecto SIGC3, LANIA - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: shared/lib again...
Thanks to Veniamin and Yoav: Veniamin Fichin wrote: If you use multiple instance Tomcat's feature, this may be the case. In Windows I'm using a single instance of tomcat, there's no CATALINA_BASE so it should be the same as CATALINA_HOME if I understand correctly. In Linux I'm using a single binary of tomcat and have the jar in CATALINA_BASE/shared/lib. Alternatively you can place your .jar in $CATALINA_HOME/common/lib . I wanted to be able to deploy my application as a regular user who owns CATALINA_BASE and has not write access to CATALINA_HOME. Thanks anyway. --- Julio César Aguilar Cabrera [EMAIL PROTECTED] Proyecto SIGC3, LANIA - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
shared/lib again...
I've read the ClassLoading part of Tomcat documentation and searched this list but I've still found no clue to my recent problem: Tomcat 5.0.19 JDK 1.4.2_03 Windows XP I have several applications running with a common jar of my own in each WEB-INF/lib and everthing works. If I move that jar to %CATALINA_HOME%/shared/lib the applications wont start reporting a CNFE about a class in the previously mentioned jar. I can reproduce the problem in Linux (same version of Tomcat and JDK) placing the jar in CATALINA_BASE/shared/lib or CATALINA_HOME/shared/lib. Is there something that has to be done to be able to share a jar through applications? Thanks for any help. --- Julio César Aguilar Cabrera [EMAIL PROTECTED] Proyecto SIGC3, LANIA - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Relative directory addressing to parent directory
In my knowledge: For tomcat to be able to serve the images, that images directory hast to live inside a web application (or be a web application by itself). If you choose to do the later, then you could use a path like /images/myimage.jpg to display those images. --- Julio César Aguilar Cabrera [EMAIL PROTECTED] Proyecto SIGC3, LANIA - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: JDBC/DBCP problems
Tomcat version is 4.1.29 on Windows XP. I'm attempting to connect to SQL Server. The JDBC driver JARs are in CATALINA_HOME\common\lib, and since everything works fine if I manually load the driver via Class.forName(), I don't think my problem is related to my driver files location. When attempting to use getConnection(), however, I get the dreaded Cannot create JDBC driver of class '' for connect URL 'null', cause: No suitable driver error. The highlights of my configuration are below. Two comments: 1. You don't mention a ResourceLink. When you define a Resource as global, you need to use a ResourceLink in the definition of the context of the application. In your case, something like ResourceLink global=jdbc/mydb name=jdbc/mydb type=javax.sql.DataSource / inside the Context tag of the server.xml COULD work. 2. I'm saying COULD in the previous comment because I had the same problem and could not solve it with Tomcat 4.1.29. Using 5.0.16 or 5.0.18 everything works fine. I have something like: server.xml GlobalNamingResources Resource name=GlobalDataSource auth=Container type=javax.sql.DataSource description=The database. / ResourceParams name=GlobalDataSource ... /ResourceParams /GlobalNamingResources --- Catalina/host/myapp.xml --- Context ... ResourceLink global=GlobalDataSource name=jdbc/mydb type=javax.sql.DataSource / /Context Note that there's no need of using a resource-ref in web.xml. --- Julio César Aguilar Cabrera [EMAIL PROTECTED] Proyecto SIGC3, LANIA - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
