Proxy Breaks Weblogic Web Service Testing
A peculiar error came up while trying to test my weblogic web service. BEA provides a test page for web services that you can use in development. So I went to the page to test my ProofOfConceptService (brilliant name, huh?). I received this error:
weblogic.webservice.tools.wsdlp.WSDLParseException: Failed to retrieve WSDL from http://localhost:80/jetspeed/ProofOfConceptService?WSDL. Please check the URL and make sure that it is a valid XML file [java.io.FileNotFoundException: Response: ‘403: Forbidden’ for url: ‘http://localhost:80/jetspeed/ProofOfConceptService?WSDL’] at weblogic.webservice.tools.wsdlp.DefinitionFactory.createDefinition(DefinitionFactory.java:126) at weblogic.webservice.tools.wsdlp.WSDLParser.(WSDLParser.java:76) at weblogic.webservice.WebServiceFactory.createFromWSDL(WebServiceFactory.java:108) at weblogic.webservice.WebServiceFactory.createFromWSDL(WebServiceFactory.java:84) at weblogic.webservice.server.servlet.ServletBase.invokeOperation(ServletBase.java:295) at weblogic.webservice.server.servlet.WebServiceServlet.invokeOperation(WebServiceServlet.java:344) at weblogic.webservice.server.servlet.ServletBase.handleGet(ServletBase.java:266) at weblogic.webservice.server.servlet.ServletBase.doGet(ServletBase.java:158) at weblogic.webservice.server.servlet.WebServiceServlet.doGet(WebServiceServlet.java:255) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at weblogic.servlet.internal.ServletStubImpl$ServletInvocationAction.run(ServletStubImpl.java:971) at weblogic.servlet.internal.ServletStubImpl.invokeServlet(ServletStubImpl.java:402) at weblogic.servlet.internal.ServletStubImpl.invokeServlet(ServletStubImpl.java:305) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext.java:6350) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:317) at weblogic.security.service.SecurityManager.runAs(SecurityManager.java:118) at weblogic.servlet.internal.WebAppServletContext.invokeServlet(WebAppServletContext.java:3635) at weblogic.servlet.internal.ServletRequestImpl.execute(ServletRequestImpl.java:2585) at weblogic.kernel.ExecuteThread.execute(ExecuteThread.java:197) at weblogic.kernel.ExecuteThread.run(ExecuteThread.java:170)
Immediately I keyed in on the “403: Forbidden”. So how can I be forbidden to access my localhost? After cruising google and bea newsgroups I only found 1 mention of this and 0 fixes. Then I thought of the line I added to my startup script that adds our proxy configuration to the JVM:
-DproxySet=true -DproxyHost=ourproxy.server.com -DproxyPort=80
This allows our Jetspeed portal to pull in web feeds through our firewall. Turns out that when I removed this the test went fine. It appears the JVM attempts to use the proxy even when I’m accessing the localhost. I guess there’s no way around this than to remove the proxy setup line everytime I want to test a local web service. Unless someone knows of a way to tell a JVM to ignore a proxy for certain hosts?
