Roland,
Thanks for the prompt response. I have tried to add the ‘stax’ dependence into the impl pom.xml and it is still not working with java 5 for sakai 2.6. Actually, it has no problem to compile the tool under java 5 even without the ‘stax’ dependence.
I also have another question: is this tool requiring Spring 2.5? I have tried to run the tool by using java 6 for sakai 2.6 and it gives me the following error (However, the tool shows up in application and it crashes when you click the tool to the first page). Sakai-2.6 is running on spring 2.0.6 version.
Any suggestion?
Thanks a lot!
Peter Liu

Subject: Re: [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,

Hi Roland,
I am very interesting on your Sakai-Contrib tool: Knowledgebase and I am trying to plugging into our Sakai 2-6-x instance.
I have downloaded your 2.7.x version and have successfully built it for Sakai-2-6-x version after modifying the pom.xml file.
However, it crashes on the tomcat 5.5.26 when I am trying to run it in Sakai 2.6.x. The following error is shown in the log file below.
It seems that it look for sjsxp.jar, which is missing. Do you have any idea how to solve it?
Thanks a lot!
