i want to change the number of threads in pool for JBoss-2.4.3_Tomcat-3.2.3 from 100 to 500. This change can be made in tomcat.src.org.apache.jasper.runtime in JspFactoryImpl.java . My problem is that if i make these changes in JspFactoryImpl.java file, then how do i compile it so that the change is available at runtime when i run JBoss with tomcat??
