Hi Jim, Yes, sorry. I was very busy yesterday and didn't have much time for responding.
The reason why it's not possible to just drop the application into an existing OpenLaszlo web application is the Java back-end system of LZProject. For a Java web application every servlet has to be mapped to a URL within the folder /WEB-INF/web.xml. Here's an example mapping: > <servlet> > <servlet-name>UserRest</servlet-name> > <display-name>REST web service for user data</display-name> > <servlet-class> > org.openlaszlo.lzproject.rest.UserRestController</servlet-class> > > <load-on-startup>1</load-on-startup> > </servlet> > > <servlet-mapping> > <servlet-name>UserRest</servlet-name> > <url-pattern>/lzproject/rest/user/*</url-pattern> > </servlet-mapping> And the Java classes have to be added the WEB-INF/classes folder. Java JAR library files have to be added to the WEB-INF/lib folder. And many more changes would need to made which would require that you open config files with text editors, add content to them, copy files around. That is A LOT MORE complicated then deploying a Java web application and - trust me - professional Java developers would never accept such an approach. Besides that the SOLO version of LZProject shows that you can deploy OpenLaszlo applications without running an OpenLaszlo server using a Java back-end. LZProject was made to show Java developers how to integrate Java applications with OpenLaszlo. If you are for example a PHP developer the tutorials published by IBM should be very helpful. http://www.donhopkins.com/drupal/node/125 If you have an OpenLaszlo server running on your system (probably using the one-click Windows installer) Tomcat is already installed with OpenLaszlo running in it. Tomcat contains a manager application making it easy to deploy WARs. Here are the docs: http://tomcat.apache.org/tomcat-5.5-doc/manager-howto.html#Deploy%20A%20New% 20Application%20from%20a%20Local%20Path Best regards, Raju > Von: Jim <[EMAIL PROTECTED]> > Datum: Thu, 25 Oct 2007 08:07:47 -0700 > An: Raju Bitter <[EMAIL PROTECTED]> > Betreff: Re: [Laszlo-dev] LZProject - Request for installation/configuration > clarification > > Hi Raju, > > Raju Bitter wrote: >> You are welcome, Jim.
