4.0.x servers should add JDK_HOME/lib/tools.jar, otherwise jmx-console might be broken -------------------------------------------------------------------------------------- Key: JBIDE-2742 URL: https://jira.jboss.org/jira/browse/JBIDE-2742 Project: Tools (JBoss Tools) Issue Type: Bug Components: JBossAS Affects Versions: 3.0.0.alpha Reporter: Galder Zamarreno Attachments: boot-jbds.log, boot-normal.log jmx-console access for AS 4.0.1.SP1 (for example) instances started via JBDS is broken. When you try to access the jmx-console, you get: ype Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception org.apache.jasper.JasperException: Unable to compile class for JSP org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:97) org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java:346) org.apache.jasper.compiler.Compiler.generateClass(Compiler.java:414) org.apache.jasper.compiler.Compiler.compile(Compiler.java:472) org.apache.jasper.compiler.Compiler.compile(Compiler.java:451) org.apache.jasper.compiler.Compiler.compile(Compiler.java:439) org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:511) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:295) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:292) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236) javax.servlet.http.HttpServlet.service(HttpServlet.java:810) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:75) root cause Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath.

Why? I suspect that run.sh adds lib/tools.jar to the classpath as shown in boot-normal.log [galder@dhcp-144-245 jdk1.5.0_12]$ find . -name "*.jar" | xargs grep com/sun/tools/javac/Main Binary file ./lib/tools.jar matches grep -nH -e "lib/tools.jar" boot-normal.log boot-normal.log:78:11:20:32,723 DEBUG [ServerInfo] java.class.path: /home/galder/access/as-rel/4.0.1.sp1/bin/run.jar:/usr/java/jdk1.5.0_12/lib/tools.jar Whereas when started from JBDS does not: grep -nH -e "lib/tools.jar" boot-jbds.log Grep finished with no matches found at Mon Sep 8 11:28:39 Please find attached both boot.log files. IMO, JBDS should be more conservative just like run.sh is which requires pointing to a JDK vs a JRE, at least for the 4.0.x series. I think you can get away with using a JRE for 4.2 or 4.3 but I'm not sure.
