When i tried to view my JSP Page,buglist.jsp the following error occurs. ____________________________________________________ No Java compiler was found to compile the generated source for the JSP. This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK to the common/lib directory of the Tomcat server, followed by a Tomcat restart. If using an alternate Java compiler, please check its installation and access path. ______________________________________________ then i intensionally did some mistake in my buglist.jsp and when i tried to view the same page, at throws the exact compiler error i.e) it is compiling now. i don't know why the above mentioned error is displayed when no such mistakes are found. i have used some static variable in that page. is it due to the static variables? Further i copied the tools.jar from the specified path, and replaced the existing tools.jar in the common/lib directory. All my jsp pages are working fine, except this page[buglist.jsp]. in this page i have used static variable to display the bugs one by one[bugs are stored in the data base]. I don't know how to resolve this one? I'm using tomcat 5.1 webserver. Data Base: SQL SERVER 6.5. thanks in advance. how to overcome this problem?
