Dear all, I am working in the development of a driver, which use the httpclient and commons-vfs.
The complete stack is: org.apache.commons.vfs.FileSystemException: Could not connect to HTTP server on "localhost". at org.apache.commons.vfs.provider.http.HttpClientFactory.createConnection(HttpClientFactory.java:186) at org.apache.commons.vfs.provider.http.HttpClientFactory.createConnection(HttpClientFactory.java:53) at org.apache.commons.vfs.provider.http.HttpFileProvider.doCreateFileSystem(HttpFileProvider.java:97) at org.apache.commons.vfs.provider.AbstractOriginatingFileProvider.getFileSystem(AbstractOriginatingFileProvider.java:103) at org.apache.commons.vfs.provider.AbstractOriginatingFileProvider.findFile(AbstractOriginatingFileProvider.java:82) at org.apache.commons.vfs.provider.AbstractOriginatingFileProvider.findFile(AbstractOriginatingFileProvider.java:66) at org.apache.commons.vfs.impl.DefaultFileSystemManager.resolveFile(DefaultFileSystemManager.java:706) at org.apache.commons.vfs.impl.DefaultFileSystemManager.resolveFile(DefaultFileSystemManager.java:623) at org.icenigrid.gridsam.core.plugin.transfer.protocol.AbstractTransferAgent.getFileObject(AbstractTransferAgent.java:239) at org.icenigrid.gridsam.core.plugin.transfer.protocol.TransferAgentFactory.resolveSourceFile(TransferAgentFactory.java:168) at org.icenigrid.gridsam.core.plugin.transfer.protocol.TransferAgentFactory.<init>(TransferAgentFactory.java:120) at org.icenigrid.gridsam.core.plugin.transfer.provider.AFTFileTransferJob.execute(AFTFileTransferJob.java:131) at org.quartz.core.JobRunShell.run(JobRunShell.java:202) at org.quartz.simpl.SimpleThreadPool $WorkerThread.run(SimpleThreadPool.java:525) Caused by: org.apache.commons.httpclient.NoHttpResponseException: The server localhost failed to respond at org.apache.commons.httpclient.HttpMethodBase.readStatusLine(Unknown Source) at org.apache.commons.httpclient.HttpMethodBase.readResponse(Unknown Source) at org.apache.commons.httpclient.HttpMethodBase.execute(Unknown Source) at org.apache.commons.httpclient.HttpMethodDirector.executeWithRetry(Unknown Source) at org.apache.commons.httpclient.HttpMethodDirector.executeMethod(Unknown Source) at org.apache.commons.httpclient.HttpClient.executeMethod(Unknown Source) at org.apache.commons.httpclient.HttpClient.executeMethod(Unknown Source) at org.apache.commons.vfs.provider.http.HttpClientFactory.createConnection(HttpClientFactory.java:182) ... 13 more The version of httpclient is 3.0.1, and I am not using any authentication mechanism. This error is found when a URI from a GASS session is requested, such as http://localhost:8180/opt/mytext.txt , where /opt/mytext.txt is on /. However, using a web server or tomcat servlet container, httpclient has not problems. Tracking the code, in the generateRequestLine method of HttpMethodBase.java, it does not receives the correct path. protected static String generateRequestLine(HttpConnection connection, String name, String requestPath, String query, String version) Thus, for the GASS session , requestPath shows: HEAD / HTTP/1.1 , instead of HEAD /opt/mytext.txt HTTP/1.1 But, using a URI of tomcat, such as http://localhost:8080/index.jsp , it shows: HEAD /index.jsp HTTP/1.1 Any comment or suggestion is welcome. Regards.
