can't start solr by java -jar start.jar

[Jill Han]

I downloaded solr1.4, and unzipped it at C:\apache-solr-1.4.0 . 

At C:\apache-solr-1.4.0\example,  I try to run solr by java -jar
start.jar as instructed by Solr tutorial.

However,  it failed.

 

C:\apache-solr-1.4.0\example>java -jar start.jar

java.lang.NullPointerException

        at java.io.File.<init>(Unknown Source)

        at org.mortbay.start.Main.start(Main.java:440)

        at org.mortbay.start.Main.main(Main.java:115)

 

any idea on what caused that?

 

I have java version "1.5.0_11" on the machine

Thanks for your help.
