Subject: RE: [aspectj-users] how to do Tomcat 5.0.12 do the ajc compiler ?
Date: Thu, 13 May 2004 08:26:12 -0700
I have been able to get it working for Tomcat 4.1.24 without modifications.
I used the COMMAND_EDITOR extension point to the aspectj compiler task that
adds any classpath library whose name ends with Weave.jar to the aspectpath
(see attached).
This note describes how to configure Tomcat 4.x to use AspectJ to
compile JSP files.
It uses the ajee.adapters.AutoAspectpathRewriter (attached) to
set up an aspectpath that includes any jars on the classpath that are
named *Weave.jar.
1. Server configuration:
<!-- in %TOMCAT_HOME%/conf/web.xml or in app/WEB-INF/web.xml -->
<servlet>
<servlet-name>ajsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>logVerbosityLevel</param-name>
<param-value>DEBUG</param-value>
</init-param>
<init-param>
<param-name>compiler</param-name>
<param-value>org.aspectj.tools.ant.taskdefs.Ajc11CompilerAdapter</param-value>
</init-param>
<init-param>
<param-name>fork</param-name>
<param-value>FALSE</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
<!-- in app/WEB-INF/web.xml for apps that use AspectJ with JSPs (or
in %TOMCAT_HOME%/conf/web.xml to always use AspectJ with JSPs) -->
<servlet-mapping>
<servlet-name>ajsp</servlet-name>
<url-pattern>*.jsp</url-pattern>
</servlet-mapping>
2. Command line set up of variables (for Windows command processor):
Set
CATALINA_OPTS=-Dorg.aspectj.tools.ant.taskdefs.AjcTask.COMMAND_EDITOR=ajee.adapters.AutoAspectpathRewriter
3. Install the relevant jars:
copy %ASPECTJ_HOME%\lib\aspectjtools.jar %TOMCAT_HOME%\common\lib
copy %ASPECTJ_HOME%\lib\aspectjrt.jar %TOMCAT_HOME%\common\lib
copy eopSupportWeave.jar %TOMCAT_HOME%\common\lib
copy <your aspect jar>Weave.jar %TOMCAT_HOME%\common\lib
or
copy <your aspect jar>Weave.jar app\WEB-INF\lib
4. When you change your aspects, you will need to delete any
precompiled jsp files; the Tomcat jsp engine (jasper) will not
recognize dependency on aspects. E.g.,
del %TOMCAT_HOME%\work\Standalone\localhost\<app>\*.java
del %TOMCAT_HOME%\work\Standalone\localhost\<app>\*.class
