[Building Sakai] crashes on KnowledgeBase tool

Hi Peter,
I've done some testing and it appears it is a JDK issue in relation to the
stax api. Sakai 2.7+ runs on JDK 1.6 which includes a stax parser, JDK 1.5
does not. I've created a test class:
import javax.xml.stream.XMLInputFactory;
public class StaxTest {
public static void main(String[] args) {
XMLInputFactory factory = XMLInputFactory.newInstance();
System.out.println(factory.toString());
}
}
If I run and compile this with JDK 1.6 I get:
# export JAVA_HOME=/usr/java/jdk1.6.0_21/
# export PATH=$JAVA_HOME/bin:$PATH
# javac StaxTest.java
# java StaxTest
com.sun.xml.internal.stream.XMLInputFactoryImpl at 45bab50a
If I switch to JDK 1.5 I need the stax-api, otherwise it won't compile:
# export JAVA_HOME=/usr/java/jdk1.5.0_19/
# export PATH=$JAVA_HOME/bin:$PATH
# javac -classpath stax-api-1.0.1.jar StaxTest.java
# java -classpath stax-api-1.0.1.jar:. StaxTest
Exception in thread "main" javax.xml.stream.FactoryConfigurationError:
Provider com.bea.xml.stream.MXParserFactory not found
at javax.xml.stream.FactoryFinder.newInstance(FactoryFinder.java:72)
at javax.xml.stream.FactoryFinder.find(FactoryFinder.java:178)
at javax.xml.stream.FactoryFinder.find(FactoryFinder.java:92)
at javax.xml.stream.XMLInputFactory.newInstance(XMLInputFactory.java:136)
at StaxTest.main(StaxTest.java:6)
Now I get the same error as you do. It turns out that it needs a stax
implementation. You pointed to sjsxp:
# java -classpath stax-api-1.0.1.jar:sjsxp-1.0.1.jar:. StaxTest
com.sun.xml.stream.ZephyrParserFactory at 768965fb
But there is also stax itself:
[root at kantoor ~]# java -classpath stax-api-1.0.1.jar:stax-1.2.0.jar:.
StaxTest
com.bea.xml.stream.MXParserFactory at 3e7ffe01
This issue can be resolved by adding one of both to the pom.xml of the
impl/pom.xm file. I'd personally go for stax:
<dependency>
<groupId>stax</groupId>
<artifactId>stax</artifactId>
<version>1.2.0</version>
</dependency>
Please let me know if this works for you. If it does, I'll create a 2.6
branch and add the dependency to the impl/pom.xml
With kind regards,
