I have defined my own class (IJC) that implements the JavaCompiler interface and am using it with Websphere 5.0. The IJC class is used instead of the default Java compiler when the JSP engines loads it (defined jspCompilerPlugin in the ibm-ext.xml file). When it attempts to load the class, it fails giving the following stack trace. [7/8/05 15:49:07:469 EDT] 5d1faf8f WebGroup E SRVE0026E: [Servlet Error]-[incert/addins/tomcat/IJC.setVerbose]: ava.lang.AbstractMethodError: incert/addins/tomcat/IJC.setVerbose at org.apache.jasper.compiler.Compiler.compile(Compiler.java:301)^M at org.apache.jasper.compiler.Compiler.compile(Compiler.java:129)^M at com.ibm.ws.webcontainer.jsp.servlet.JspServlet.loadJSP(JspServlet.jav a:926)^M at com.ibm.ws.webcontainer.jsp.servlet.JspServlet$JspServletWrapper.load IfNecessary(JspServlet.java:285)^M . . . (only posted the relevant part of the stack trace). Where is setVerbose defined? I can't seem to find it in the javadoc pages for JavaCompiler. thanks, James
