Debugging Java Extensions
The XSLT/XQuery debugger does not step into Java classes that are configured as XSLT/XQuery extensions of the transformation. To step into Java classes, inspect variable values, and set breakpoints in Java methods, you can set up a Java debug configuration in an IDE (such as the Eclipse SDK) as described in the following steps:
- Create a debug configuration.
- Set at least 256 MB as heap memory for the Java virtual machine (recommended 512
MB) by setting the
-Xmxparameter in the debug configuration (for example,-Xmx512m
). - Make sure the
[OXYGEN_INSTALL_DIR]/lib/oxygen.jarfile and your Java extension classes are on the Java classpath.The Java extension classes should be the same classes that were set as an extension of the XSLT/XQuery transformation in the debugging perspective. - Set the class
ro.sync.exml.Oxygenas the main Java class of the configuration.The main Java classro.sync.exml.Oxygenis located in theoxygen.jarfile.
- Set at least 256 MB as heap memory for the Java virtual machine (recommended 512
MB) by setting the
- Start the debug configuration.Now you can set breakpoints and inspect Java variables as in any Java debugging process executed in the selected IDE (Eclipse SDK, and so on.).
