Caused by: org.xml.sax.SAXParseException:
Cause
The following error indicates a problem with the accessExternalSchema property in the IBM WebSphere Java Development Kit (JDK), Java Runtime Environment (JRE), and Java Virtual Machine (JVM):
Caused by: java.lang.AssertionError: org.xml.sax.SAXParseException:
Failed to read external schema document
jar:file:/C:/IBM/WebSphere90/AppServer/plugins/
com.ibm.jaxb.tools.jar!/com/ibm/jtc/jax/tools/
xjc/reader/xmlschema/bindinfo/xjc.xsd",
because "jar" access is not allowed.
Resolving The Problem
Follow these steps to prevent the error:
- Open the xjc.bat located in the <WebSphere_Install_Dir>\bin folder. By default, this folder is C:\IBM\WebSphere90\AppServer\bin
- Add the -Djavax.xml.accessExternalSchema=all JVM argument to the Java command:
"%JAVA_HOME%\bin\java" -Djavax.xml.accessExternalSchema=all -Djava.ext.dirs="%WAS_JAVA_EXT_DIRS%" -Djava.endorsed.dirs="%WAS_ENDORSED_DIRS%" %OSGI_INSTALL% %OSGI_CFG% %WAS_LOGGING% %CONSOLE_ENCODING% -Dwas.install.root="%WAS_HOME%" -Dws.ext.dirs="%WAS_EXT_DIRS%" %USER_INSTALL_PROP% -Xbootclasspath/p:"%WAS_BOOTCLASSPATH%" -classpath "%WAS_CLASSPATH%" com.ibm.ws.bootstrap. WSLauncher com.ibm.ws.jaxb.tools.XJC %* set RC=%ERRORLEVEL% - Save the file and generate Java again
