Hi, It looks like a bug in the code. Please open a bug report for it http://issues.apache.org/jira/browse/XALANJ
By the way, I did some performance comparison long time ago, it showed that serialize and deserialize a Template object is slower than regenerate a Template object from a stylesheet. If you want to get better performance, you can use XSLTC, you can compile a stylesheet into a translet (a java class), then you can do transformation later. More details please refer to http://xml.apache.org/xalan-j/xsltc_usage.html Hope it helps, Christine Li XSLT Development IBM Toronto Lab Tel: (905)413-2601 Email: [EMAIL PROTECTED] tiberiu <[EMAIL PROTECTED]> 01/08/2007 03:42 PM To xalan-j-users@xml.apache.org cc Subject is StylesheetRoot really java.io.Serializable ? Hi, in xalan documentation there is a hint to use Templates and to cache them, in order to increase performance. I need to cache them on disk, so that I tried to use (java.io) Serializable interface. The Problem is that even if StyleSheetRoot (the Templates Object) implements Serializable, ExtensionNamespaceSupport doesn't. So, trying to save a StylesheetRoot with xalan2.4.0 crashes, in 2.7.0 I didn't obtain an error but the read Class from such a File return on method StylesheetRoot.getExtensions() a null. This null is at the end converted in an "Unknown Error in XPath" Error because of the following Code from ExtensionsTable class: Vector extensions = m_sroot.getExtensions(); for (int i = 0; i < extensions.size(); i++) Without these Extensions the Templates doesn't know defined Namespaces. My Question is if it is a possibility to serialize StylesheetRoot in a File, and to can use that serialized form in order to generate a good Transformer. Thanks for an answer.
