Ravi, I don't have a lot of suggestions, but I do have a lot of questions. 1. What is the exact version of Tomcat 7? 2. What is the exact version of Java that you are running? 3. What are specific examples of some errors you are encountering? Please include actual log entries, and not summations. The traditional way of deploying applications on Tomcat is through a WAR file. Please read the following on how to deploy applications to Tomcat. http://tomcat.apache.org/tomcat-7.0-doc/appdev/deployment.html I'm a little suspicious of several things: 1. Creating a special directory on Solaris Normally (unless you use contexts - see reference above), the web application should be placed in the appBase directory as defined in server.xml. This is typically $CATALINA_BASE/webapps. 2. Runs on Windows but does not run on Solaris Depending on the errors, this could be one of several things. a) CLASSPATH issues b) JNI libraries c) JDBC drivers - if your application talks to a database d) Permissions problems Let's take these one at a time. It's been my experience (and I'll probably get a talking-to for this) that Eclipse users tend to mangle CLASSPATH settings in order to get web applications to work. All application resources (except container managed resources) belong in one of two places: WEB-INF/lib - for JAR files WEB-INF/classes - for class files and other resources like log4j.xml Eclipse in its normal settings will include these two directories on the build path, and copy compiled classes to WEB-INF/classes. There should be no reason to alter the CLASSPATH. JNI (Java Native Interface) is way to marry native code and Java code (loosely speaking). Obviously native code compiled for Windows will not run on a Solaris system. JDBC drivers enable your application to communicate with a database. If the database connection is controlled by Tomcat (and you access it via a JNDI pooled connection - highly recommended), you need to place the JDBC driver inside $CATALINA_BASE/lib. Otherwise, if you manage your own database connections, the JAR containing the JDBC driver belongs with your other resources - in WEB-INF/lib. It's odd that the client's IT department created a special folder for your web application. I wonder if the user running Tomcat has permissions to read the directory they created - and that the permissions of the files you copied are proper as well. If the above does not address your particular situation, then I'm afraid I'm at the end of my crystal ball (mixed metaphors are fun). Please answer the questions posed at the beginning of my reply, and hopefully others will have ideas. . . . just my (procrastinating) 2 cents /mde/ --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
