Eclipse, consuming a web service gives java.lang.reflect.InvocationTargetException -

would help. spent lot of hours trying solve problem, searching in web, sites - , questions here - still no answer this. appreciated.

i'm not means specialist in this, information may vague i'll try to use best terms describe problem.

when try consume webservice myself created using eclipse, in java language, using apache tomcat 6, gives me error:

the content of body cannot displayed in form view. please switch source view examine raw content.

i tested webservice (the 11 methods) java application , junit test , fine. methods delete, add, modify, , search information in database on mysql. said, methods run java application.

i tried generate client on different project. if try consume web service client, gives me error:

i remember saying cause hostname called "mauricio-pc" , tomcat couldn't recognize it. don't know if that's true.

so, appreciated. feel free ask questions.

thanks.

edit: had created project name, serviciocapacitacion instead of sistemacapacitacion. same files. reimported .jars.

so have libraries:

library apache tomcat v6.0:   annotations-api.jar   catalina-ant.jar   catalina-ha.jar   catalina-tribes.jar   catalina.jar   ecj-3.7.2.jar   el-api.jar   gson-2.2.3.jar   jasper-el.jar   jasper.jar   jsp-api.jar   mysql-connector-java-5.1.25-bin.jar   orm.jar   servlet-api.jar   tomcat-coyote.jar   tomcat-dbcp.jar   tomcat-i18n-es.jar   tomcat-i18n-fr.jar   tomcat-i18n-ja.jar  jre system library:   resources.jar   rt.jar   jsse.jar   jce.jar   charsets.jar   jfr.jar   access-bridge-64.jar   dnsns.jar   jaccess.jar   localedata.jar   sunec.jar   sunjce_provider.jar   sunmscapi.jar   zipfs.jar  junit 4:    junit.jar   org.hamcrest.core_1.1.0.v20090501071000.jar  web app libraries:   axis.jar   commons-discovery-0.2.jar   commons-logging.jar   jaxrpc.jar   saaj.jar   wsdl4j.jar    gwt-dev.jar    <- these alone, not inside library gwt-servlet.jar mail.jar 

and inside directory webcontent>web-inf>lib there these libraries:

axis.jar commons-discovery-0.2.jar commons-logging.jar jaxrpc.jar saaj.jar wsdl4j.jar 

i know these libraries repeated, question is, have delete 1 of these groups? group eliminate/move , group keep? there "good" method remove them?
