Debugging a Web Application

Use Web page and managed bean breakpoints to debug the Web application.

Prerequisites

Start EAServer or Tomcat in debug mode.

Optionally, you can enable the JPDA (Java Platform Debug Architecture) interface in EAServer to allow debugging of Java Services that are deployed to the Service Container runtime environment.

Set your JPDA options for EAServer by editing the djc-setenv.bat file located in the DevRuntimes/EAServer/bin subdirectory of your WorkSpace installation. You can edit any of these properties, shown here with there default settings:

set DJC_JPDA=false
set DJC_JPDA_PORT=5005
set DJC_JPDA_SUSPEND=n
set DJC_JPDA_ARGS=

For additional information about these settings, see the EAServer documentation located at the main level of the Sybase WorkSpace online bookshelf. If this server documentation is not installed, the documentation is available on the Sybase Product Manuals Web site at http://sybooks.sybase.com/nav/base.do

You must either run the Web application on Apache Tomcat server, or deploy the Web application to EAServer to execute breakpoints. Tomcat supports both managed bean and Web page breakpoints. EAServer supports managed bean breakpoints.

In the WorkSpace Navigator of the Web Application Development perspective, select the Web application project that you want to debug .
Right-click and select either Debug or Debug as > Debug on Server.

Do one of the following:
