I am trying to show reports trough a web service as describe in the JasperServer-Web-Services-guide.pdf (Section 2.4.2) I'm getting a server error: java.lang.NoClassDefFoundError: Could not initialize class com.jaspersoft.jasperserver.ws.xml.Unmarshaller I have already look into the jar's attached to my project and found this class, i also try to download the jar again and change it but i got the same result. Does anyone have any idea what could be wrong? Thank you Code: String webServiceUrl = "http://alfresco:8080/jasperserver/"; String username = "jasperadmin"; String password = "jasperadmin"; MyJIClient client = new MyJIClient(webServiceUrl, username, password); String uri ="http://alfresco:8080/jasperserver/"; List ls = client.list(uri); Post Edited by wichogg at 05/09/2011 19:45
