with tc7.0.28 from current debian stable I got the problem. As per http://stackoverflow.com/questions/19243458/tomcat7-not-compiling-jsp-examples , I got a 7.0.56, but the problem still persists org.apache.jasper.JasperException: Unable to compile class for JSP: An error occurred at line: [1] in the generated java file: [my_jsp.java] The type java.util.Map$Entry cannot be resolved.

Care to post a sample JSP? Are you sure you don't have an old ECJ library laying around?
thanks, had eclipse-ecj-3.5.1.jar now have /usr/share/java/eclipse-ecj-4.4.jar ----------- and if after installing the jar there, you see java.util.MissingResourceException: Can't find bundle for base name org.eclipse.jdt.internal.compiler.parser.readableNames, locale en_US java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1564) java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:1387) java.util.ResourceBundle.getBundle(ResourceBundle.java:845) org.eclipse.jdt.internal.compiler.parser.Parser.readReadableNameTable(Parser.java:710) org.eclipse.jdt.internal.compiler.parser.Parser.initTables(Parser.java:604) then you better change the permissions on the file. ;) If you then see java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.jdt.internal.compiler.parser.Parser org.eclipse.jdt.internal.compiler.Compiler.initializeParser(Compiler.java:681) org.eclipse.jdt.internal.compiler.Compiler.<init>(Compiler.java:282) you better restart eclipse and the tomcat therein
