Hello, I was testing Novell Portal servers running under Tomcat 3.3 and IIS5. I decided to switch to the in-process adapter using JNI as opposed to the out of process method. Most everything seemed to work fine, except I receive the following error with one of our servlets: ----- Error: http://npsdev.bdo.com/nps/portal/gadgets/com.novell.nps.authentication.Authenticator/skins/bdo/devices/default/main.xsl (161): <input>: result handler error: java.io.IOException: JNI startReasponse implementation error Error: com.novell.xsl.result.ResultException: java.io.IOException: JNI implementation error 2001-12-07 15:05:52 - Ctx(/nps) : IOException in R( /nps + /servlet/portal + null) - java.io.IOException: JNI implementation error at org.apache.tomcat.modules.server.JNIResponseAdapter.doWrite(Unknown Source) at org.apache.tomcat.core.OutputBuffer.realWriteBytes(Unknown Source) at org.apache.tomcat.util.buf.ByteChunk.flushBuffer(Unknown Source) at org.apache.tomcat.core.OutputBuffer.flush(Unknown Source) at org.apache.tomcat.core.OutputBuffer.close(Unknown Source) at org.apache.tomcat.core.Response.finish(Unknown Source) at org.apache.tomcat.core.ContextManager.service(Unknown Source) at org.apache.tomcat.modules.server.JNIConnectionHandler.processConnection(Unknown Source) at org.apache.tomcat.modules.server.JNIEndpoint.service(Unknown Source) ------ If I don't use the JNI in-process adapter this works fine, which makes me tend to believe it could be a problem with this. This code prompts the user to select a file from their local system (which is a zip file basically) which then gets extracted and installed on the server on which the servlet is running. I'm not sure if this is where the issue is, but I thought I would bring it to your attention. Any insight you can provide on this would be appreciated. Thanks!
