CTL4j AddCI *********** This is a simple example which demonstrates how you can use the Component Template Library for Java (CTL4j) to realise distributed and parallel component-based software systems. The implemented component offers different versions of the add operator. **** Usage **** 1) Put the CTL4j.jar and additional JARs into lib/. 2) Create a locs.txt with valid locations. When using a Java interface as CI, the 'lib' transport is not available by default (see build.xml on how you can enable it), therefore a valid one looks like this: 'user@host:/path/to/AddCI/service/src/Add.exe tcp'. If you do not use SSH keys, the password needs to be specified in the location ('user:pass@host...') if run from Ant. In other cases, you will be prompted for a password. 3) Compile and run. **** Tutorial **** This CTL4j example consists of three major parts: + common.Add, the Java interface of the component + Impl.AddImpl, an implementation of that interface + Client, an application which uses the component In addition to that, there are the following files: + service/src/Add.exe, script for setting up the JVM (can be copied) + service/src/Add.java, service code (can be renamed, then copied) + classdef.txt, defines the relation between RIs + build.xml, build rules; shows how to invoke the CTL4j's code generator to generate CI, RI, Local and possibly Debug wrappers for the component. For more information about the specific parts, consult the in-file comments. **** Bug reports and questions **** While executing, all CTL4j code writes logfiles, the client writes to /tmp/client-0.log and the service to /tmp/service.log. When reporting about runtime failures, you should include this information. Any comments about how good the example can be understood are appreciated. -- Boris Buegling
