# XML limitations

The following table lists the limitations on XML data types in Derby.

Table 1. XML limitations
Issue | Limitation
--- | ---
Length of XML | 2,147,483,647 characters
Use of XML operators | Requires that the JAXP parser classes (such as Apache Xerces) and the Apache Xalan classes are in the classpath. Attempts to use XML operators without these classes in the classpath result in an error. In some situations, you may need to take steps to place the parser and Xalan in your classpath. See "XML data types and operators" in the Java DB Developer's Guide for details.
