Upload applet error

[Antonio Rueda]

Hi to all.
 
I'm getting the following error when trying to call the upload applet in a remote server. I'm getting the same error in Ubuntu 12.04 (XNAT Desktop VM instance) and Windows 7 terminals. The upload applet works fine when used in the local instance of the Ubuntu VM.

Applet startup failed; please contact admini...@xnat.org for help.

[Herrick, Rick]

Obviously you can access the XNAT application itself from your browser, so I don't think it's a firewall issue. Can you do a view-source on the page in which the applet is embedded and have a look at the code around the applet launch? I'm wondering if there's something weird going on with the parameters being passed to the applet…

Can you do a view-source on the page in which the applet is embedded and have a look at the code around the applet launch? 

Here's loadApplet, the full source for the page is attached. 

function loadApplet() {
	var attributes = { code: 'org.nrg.upload.ui.UploadAssistantApplet', codebase: '/xnat/applet/', width: 800, height: 500, /* class: 'upload_applet', */ archive: 'UploadAssistant-1.6.3.jar, DicomEdit-4.0.0.jar, DicomUtils-1.3.1.jar, antlr-2.7.7.jar, antlr-runtime-3.4.jar, common-1.2.0.jar, commons-codec-1.5.jar, commons-lang-2.6.jar, dcm4che-core-2.0.25.jar, dicom-xnat-sop-1.6.3.jar, dicom-xnat-util-1.6.3.jar, ecat-edit-0.2.0.jar, ecat-io-0.1.0.jar, guava-12.0.1.jar, java-uuid-generator-3.1.3.jar, javax.inject-1.jar, jcalendar-1.4.jar, joda-time-2.1.jar, json-20090211.jar, jsr305-1.3.9.jar, log4j-1.2.16.jar, looks-2.4.1.jar, nrgutil-1.1.0.jar, slf4j-api-1.6.6.jar, slf4j-log4j12-1.6.6.jar, stringtemplate-3.2.1.jar, wizard-1.1.jar' };
