[xwiki-users] Groovy JAR attach - xwiki-users@xwiki.org

9 Jun 2010

Hi xwiki-users,

I seem to be having trouble including JARs in my Groovy classpath.  I'm
trying the following:

{{groovy jars="attach:test-1.0.jar"}}
try {
  def x = Class.forName("com.test.TestMe")
  out.println(x)
}
catch(e) {
   out.println("FAILURE: " + e)
}
{{/groovy}}

This ends up with the text "FAILURE: ClassNotFoundException", but if I
change the first line to:

  Class.forName("com.test.TestMe", false, this.getClass().getClassLoader())

it seems to work.  But, when I try this instead:

{{groovy jars="attach:wiki:Sandbox.Test"}}
try {
  def x = Class.forName("com.test.TestMe", false,
this.getClass().getClassLoader())
  out.println(x)
}
catch(e) {
   out.println("FAILURE: " + e)
}
{{/groovy}}

it "red-boxes" me with a NullPointerException at the end (at
com.xpn.xwiki.doc.DefaultDocumentAccessBridge.getAttachmentContent(DefaultDocumentAccessBridge.java:510)).
And, same issue if I try it without the ClassLoader.

Ultimately, I'm trying to wrap this in a WikiMacro, but none of these
options work if I put the code in a WikiMacro object.  Anyone have luck with
JAR attachments?  Thanks in advance!
