As a fallback mechanism, the standard JRE has an XML Parser built in already (an older version of xerces with some customizations - one of which is that it is not in the regular apache package.... so you cannot call it org.apache.xerces.parsers.SAXParser). So, you do not need to have any third-party jar unless you want one. I would still recommend adding xerces to your classpath though (and with it, you will want the xml-apis.jar).<br><br>So, in your 'old' code, if you used to do:<br><br>... = new SAXBuilder("org.apache.xerces.parsers.SAXParser");<br><br>then I suggest you either:<br> - add (only) xerces (with xmlapis.jar) to the classpath, and use the plain ... = new SAXBuilder(); constructor....<br> - add xerces to the classpath, use ... = new SAXBuilder(new XMLReaderSAX2Factory(false, "org.apache.xerces.parsers.SAXParser"));<br><br>Note though, that the deprecated/'old' constructor new SAXBuilder("org.apache.xerces.parsers.SAXParser"); will still work (with a deprecated warning) if you have the xerces.jar in your classpath.<br><br>I recommend that you use the (newer) JAXP API for constructing SAXBuilders. You can still customize it with a particular library.<br><br>I note that there is a lack of functionality in JDOM for using JAXP with a custom factory.... I will add that.... I think.... see issue #89<br><br>For what it's worth, the documentation on the org.jdom.input.sax is fairly comprehensive: <a href="http://www.jdom.org/docs/apidocs/org/jdom2/input/sax/package-summary.html">http://www.jdom.org/docs/apidocs/org/jdom2/input/sax/package-summary.html</a> even though it does not have an example of what you want (although it has other examples).<br><br>Also, the source code for the deprecated constructor is educational... :<br><a href="https://github.com/hunterhacker/jdom/blob/master/core/src/java/org/jdom2/input/SAXBuilder.java#L266">https://github.com/hunterhacker/jdom/blob/master/core/src/java/org/jdom2/input/SAXBuilder.java#L266</a><br>and<br><a href="https://github.com/hunterhacker/jdom/blob/master/core/src/java/org/jdom2/input/SAXBuilder.java#L288">https://github.com/hunterhacker/jdom/blob/master/core/src/java/org/jdom2/input/SAXBuilder.java#L288</a><br><br>I will consider the usage of a JAXP custom factory using the 'other' JAXP constructor: <a href="http://docs.oracle.com/javase/6/docs/api/javax/xml/parsers/SAXParserFactory.html#newInstance%28java.lang.String,%20java.lang.ClassLoader%29">http://docs.oracle.com/javase/6/docs/api/javax/xml/parsers/SAXParserFactory.html#newInstance%28java.lang.String,%20java.lang.ClassLoader%29</a><br><br>Issue #89: <a href="https://github.com/hunterhacker/jdom/issues/89">https://github.com/hunterhacker/jdom/issues/89</a><br><br>Rolf<br><br>On 21/08/2012 1:23 PM, Craig Christophersen wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal>Hello;<o:p></o:p></p><p class=MsoNormal>While I now have jdom2 compiling OK in an application, I am running into runtime problems with SAXBuilder.<o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>With previous jdom both SAXBuilder builder = new SAXBuilder(); and SAXBuilder builder = new SAXBuilder(“<u><span style='font-size:10.0pt;font-family:Consolas;color:#2A00FF'>org.apache.xerces.parsers.SAXParser</span></u>”);<span style='font-size:10.0pt;font-family:Consolas'> worked for constructing a SAXBuilder.</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:Consolas'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:Consolas'>Question:</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:Consolas'>So now to use new SAXBuilder() (which uses JAXP) do I need something additional in my classpath?? </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:Consolas'>Or is there somewhere I can see an example of what is mentioned in the migration guide ---</span> <b>Deprecated.</b> <i>use <a href="http://www.jdom.org/docs/apidocs/org/jdom2/input/SAXBuilder.html#SAXBuilder%28org.jdom2.input.sax.XMLReaderJDOMFactory%29"><code><span style='font-size:10.0pt'>SAXBuilder(XMLReaderJDOMFactory)</span></code></a> with <a href="http://www.jdom.org/docs/apidocs/org/jdom2/input/sax/XMLReaderSAX2Factory.html#XMLReaderSAX2Factory%28boolean,%20java.lang.String%29"><code><span style='font-size:10.0pt'>XMLReaderSAX2Factory.XMLReaderSAX2Factory(boolean, String)</span></code></a>?</i><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:Consolas'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:Consolas'>Thanks, </span><o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>Craig Christophersen<o:p></o:p></p><p class=MsoNormal>Software Developer<o:p></o:p></p><p class=MsoNormal>Synesis7<o:p></o:p></p><p class=MsoNormal><a href="mailto:craigch@synesis7.com">craigch@synesis7.com</a><o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><br><br><br><o:p></o:p></span></p><pre>_______________________________________________<o:p></o:p></pre><pre>To control your jdom-interest membership:<o:p></o:p></pre><pre><a href="http://www.jdom.org/mailman/options/jdom-interest/youraddr@yourhost.com">http://www.jdom.org/mailman/options/jdom-interest/youraddr@yourhost.com</a><o:p></o:p></pre></blockquote><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p> </o:p></span></p></div></body></html>
