Title: SV: Including jar files in my web app ?

Hi Eddie,   I have been experiencing the same classpath-related problems. Searching through this maillinglist i found out more people have problems with this.   One thing that seems to be working is starting orion without -jar orion.jar but with com.evermind.server.ApplicationServer but still it seems you need to put all application-specific classes in the classpath before starting orion because when i put <classpath path="./WEB-INF/lib/" /> in my orion-web.xml (where i have a jar-file containing application-specific classes in the WEB-INF/lib-dir.) and startup orion with just the normal orion-jars and without the application-specific classes in the classpath he still can't find the classes. But when i put them in the classpath when starting orion, there are no problems.   But when only this way works, what's the use of the <classpath../>-tag (and other classpath/library-related tags) when it's not working anyway without putting them all in the classpath before starting orion ?   So my question also is, is there a standard way, not putting al the application-classes in the classpath before starting orion, of solving these kind of classpath-problems? Because this way, when i add a new application i also may have to change my startup-script which can't be how it's supposed to be, or at least i think so.(?)   Any help and/or thoughts on this matter would be greatly appreciated!   Jasper.   ----- Original Message ----- From: Eddie To: Orion-Interest Sent: Wednesday, April 11, 2001 6:53 PM Subject: Re: Including jar files in my web app ? Hi Magnus and others ofcourse,   It has been a while since this issue passed by, but that is because we have been struggling with it since. I am still not able to include jar files that I put in my WEB-INF/lib dir, particular: velocity.jar. Also someone else in this newsgroup has been busy with it, on orion 1.4.7, on the same application on a different machine and has the same problem. BTW: I am able to use the jar when i put it in orion/config/application.xml with <library path...> it works but it contains a static class and I need one for every application.  Everytime I get the error that it can't find the class (ClassDefNotFound). What I tried: - Just putting them in the WEB-INF/lib dir, but it can't find it. - putting the velocity.jar in other places, like in the root of the application. - jar file in the WEB-INF/lib and putting the following tag in the orion-web.xml:         <classpath path="./WEB-INF/lib/" /> - and also tried         <classpath path="./WEB-INF/lib/velocity.jar" /> - unpacking the jar and putting it in the WEB-INF/classes dir where the servlets are located in packages that I call through servlet ref's - When I put the WEB-INF/lib/velocity.jar in the CLASSPATH, yes it does find it, but then all applications find the same velocity.jar and that doesn't work.!!! - Tried to include the jar int the META-INF/application.xml:  <module>   <ejb>/opt/Orion/lib/counter.jar</ejb>  </module>  but is than complains: ------- Error auto-deploying application-client at velocity.jar: Unable to find/read assembly info for /home/development/sgs/velocity.jar (META-INF/application-client.xml) -------- The file exists and has the necessary tags, only it is empty as I don't know what to put in it. - I find in the newsgroup archive, that solved the problem by starting orion with: com.evermind.server.ApplicationServer insted through orion.jar - I think I tried some more things.... but reallu nothing worked.   PLEASSE tell me how I can see where Orion looks for the jar file, as this problem is really driving my comletely nuts...!! I found a lot of little things about this subject. I tried about everyting, but nothing helped. I lost the logic here, so hope that someone can help me out, here, otherwise I .....   Eddie :(             ----- Original Message ----- From: Magnus Rydin To: Orion-Interest Sent: Thursday, April 05, 2001 11:05 AM Subject: SV: Including jar files in my web app ?
