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!
