I have done some more research today. Still present in 8.0. This can be fixed. Suggested fix: In org.apache.jasper.compiler.TagPluginManager class package glassfish-jsp-parser-4.0. change: Class.forName(pluginClassStr).asSubclass(TagPlugin.class); to: ctxt.getClassLoader().loadClass(pluginClassStr).asSubclass(TagPlugin.class); More info: This change enable usage of tag plugins extensions from project. This should be fixed in Glassfish javax.servlet.jsp package too. Similar problem has been solved in tomcat 7.0.42 https://issues.apache.org/bugzilla/show_bug.cgi?id=54964. This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue. Thanks for your cooperation, NetBeans IDE 8.2 Release Boss |
This is NetBeans JSP parser problem. Project will run fine. Netbeans display ClassNotFoundException, if custom tag plugins are used for JSP compilation (WEB-INF/tagPlugins.xml). If Glassfish tag plugins are used, NetBeans works fine. How to reproduce: 1. Create new web project. 2. Add tomcat-jasper library (or other library with tag plugin class). 3. Add tagPlugins.xml file into WEB-INF: <?xml version="1.0"?> <tag-plugins> <tag-plugin> <tag-class>org.apache.taglibs.standard.tag.rt.core.IfTag</tag-class> <plugin-class>org.apache.jasper.tagplugins.jstl.core.If</plugin-class> </tag-plugin> </tag-plugins> 4. Open jsp file. You will get error: java.lang.ClassNotFoundException: org.apache.jasper.tagplugins.jstl.core.If It seems like jsp parser, which is based on Glassfish, doesn't use project libraries.
