Fatal Exception thrown from a referenced library? up vote 4 down vote favorite 1 I am using a referenced library called 'rome-1.0.jar'. try { SyndFeedInput input = new SyndFeedInput(); SyndFeed feed = input.build(new XmlReader(file)); } catch(Exception e) { Log.e("", "ROME parse error: " + e.toString()); } input.build(new XmlReader(file)); is 'rome-1.0.jar' library call. Although I am catching all Exceptions, my app still crashes. 05-31 13:43:06.297: W/dalvikvm(11150): threadid=22: thread exiting with uncaught exception (group=0x40a4d1f8) 05-31 13:43:06.307: E/AndroidRuntime(11150): FATAL EXCEPTION: Thread-4199 05-31 13:43:06.307: E/AndroidRuntime(11150): java.lang.NoClassDefFoundError: java.beans.PropertyDescriptor[] 05-31 13:43:06.307: E/AndroidRuntime(11150): at com.sun.syndication.feed.impl.BeanIntrospector.getPropertyDescriptors(BeanIntrospector.java:39) 05-31 13:43:06.307: E/AndroidRuntime(11150): at com.sun.syndication.feed.impl.CloneableBean.beanClone(CloneableBean.java:129) 05-31 13:43:06.307: E/AndroidRuntime(11150): at com.sun.syndication.feed.impl.ObjectBean.clone(ObjectBean.java:87) 05-31 13:43:06.307: E/AndroidRuntime(11150): at com.sun.syndication.feed.module.DCModuleImpl.clone(DCModuleImpl.java:771) 05-31 13:43:06.307: E/AndroidRuntime(11150): at com.sun.syndication.feed.module.impl.ModuleUtils.cloneModules(ModuleUtils.java:35) 05-31 13:43:06.307: E/AndroidRuntime(11150): at com.sun.syndication.feed.synd.impl.ConverterForRSS090.createSyndEntry(ConverterForRSS090.java:90) 05-31 13:43:06.307: E/AndroidRuntime(11150): at com.sun.syndication.feed.synd.impl.ConverterForRSS091Userland.createSyndEntry(ConverterForRSS091Userland.java:85) 05-31 13:43:06.307: E/AndroidRuntime(11150): at com.sun.syndication.feed.synd.impl.ConverterForRSS092.createSyndEntry(ConverterForRSS092.java:46) 05-31 13:43:06.307: E/AndroidRuntime(11150): at com.sun.syndication.feed.sy

This will include unanticipated RuntimeExceptions but also custom exceptions which are thrown when critical resources are unavailable or otherwise fail (e.g. a settings file not found, or a server communication error). http://stackoverflow.com/questions/2616577/where-to-handle-fatal-exceptions The UncaughtExceptionHandler will do different things depending on the specific custom exception (and one thing for all the unanticipated), but in all cases the application will show the user an error message and exit. The alternative would be to keep the UncaughtExceptionHandler for all unanticipated exceptions, but handle all other fatal scenarios close to their origin. Is the design I'm considering sound, or should I use the alternative? What is the typical approach used for handling fatal exceptions? java design exception share|improve this question edited Apr 11 '10 at 9:41 asked Apr 11 '10 at 9:34 Stephen Swensen 17.1k45299 I find Bruce Eckel's article very enlightening - mindview.net/Etc/Discussions/CheckedExceptions. I would recommend you go through it. Essentially, use Unchecked Exceptions and handle them at the top level (i.e. central place). But when you must, you can also handle them at the place where the exception is generated. –Sripathi Krishnan Apr 11 '10 at 17:46 Thanks for the good read. My background is in C# so Java's checked exceptions have been a frustration for me. While ugly, I've learned as so many others have

However, sometimes you need to catch specific Errors. If you're writing framework-ish code (loading 3rd party classes), it might be wise to catch LinkageErrors (no class def found, unsatisfied link, incompatible class change). I've also seen some stupid 3rd-party code throwing sublcasses of Errors, so you'll have to handle these either. By the way, I'm not sure it isn't possible to recover from OutOfMemory. share|improve this answer answered Dec 9 '08 at 14:12 Yoni Roit 17.1k42530 2 That I had to do exactly to load DLLs, that would fail if they were not correctly configured. Not a fatal error in case of this application. –Mario Ortegón Dec 11 '08 at 10:11 5 It sometimes makes sense to catch OutOfMemoryError - for example when you are creating large array lists. –SpaceTrucker Mar 14 '13 at 7:11 1 @YoniRoit - what errors was the 3rd party code throwing? –Demi Aug 19 '13 at 3:38 2 @SpaceTrucker: does that approach
⋅ 0 Comments ⋅ Tags: error, fatalerror, java, sax, xml Tweet TweetToday we are going to talk about error handling while using SAX parser in Java. Since SAX parser is a stream parser you can handle errors while the parser is working. Here is sample project structure. Java SAX parsing error - Eclipse Project Parsing handler class implementation is simple. This implementation displays tags and the content being parsed. This class contains error and fatalError methods that are called if an error occurs. error - this method is called whenever a minor error is detected. For example XML document doesn’t validate against the schema. fatalError - this method is called when a fatal error is detected and further document processing is impossible. For example when XML file is broken. CustomParseHandler.java package com.itcuties.java; import org.xml.sax.Attributes; import org.xml.sax.SAXException; import org.xml.sax.SAXParseException; import org.xml.sax.helpers.DefaultHandler; public class CustomParseHandler extends DefaultHandler { @Override public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException { System.out.print("<"+qName+">"); } @Override public void endElement(String uri, String localName, String qName) throws SAXException { System.out.print(""+qName+">"); } @Override public void characters(char[] ch, int start, int length) throws SAXException { System.out.print("\t" + new String(ch, start, length)); } @Override public void error(SAXParseException e) throws SAXException { System.out.println("Error: " + e.getMessage()); } @Override public void fatalError(SAXParseException e) throws SAXException { System.out.println("Fatal error: " + e.getMessage()); } } Here is the code that starts the parsing process. The SAXParserFactory.setNamespaceAware(true) and SAXParserFactory.setValidating(true) methods are used to allow the SAXParser to validate XML documents. SaxParserRunner.java package com.itcuties.java; import java.io.File; import java.io.IOException; import javax.xml.parsers.ParserConfigurationException; import javax.xml.parsers.SAXParser; import javax.xml.parsers.SAXParserFactory; import org.xml.sax.SAXException; public class SaxParserRunner { public static void main(String[] args) { try { SAXParserFactory factory = SAXParserFactory.newInstance(); factory.setNamespaceAware(true); factory.setValidating(true); // Using factory we create a new SAX Parser instance SAXParser saxParser
