I am receiving the following exception message in the Tomcat log when attempting to do a multi-part upload: 20 Mar 2018 10:21:13 [https-openssl-nio2-443-exec-9] DEBUG org.apache.cxf.jaxrs.interceptor.JAXRSInInterceptor - Found operation: submitBatch 20 Mar 2018 10:21:13 [https-openssl-nio2-443-exec-9] DEBUG org.apache.cxf.attachment.AttachmentDeserializer - The attachment header size has exceeded the configured parameter: 300 20 Mar 2018 10:21:14 [https-openssl-nio2-443-exec-9] WARN org.apache.cxf.jaxrs.impl.WebApplicationExceptionMapper - javax.ws.rs.WebApplicationException: HTTP 413 Request Entity Too Large at org.apache.cxf.jaxrs.ext.MessageContextImpl.get(MessageContextImpl.java:84)
I have found numerous posts that address this issue for Tomcat 8.5 and I have tried a number of them, but none worked. I added maxHttpHeaderSize="122880000" to my SSL Connector config in server.xml but this made no difference. Here is my SSL Connector config: <Connector port="443" protocol="org.apache.coyote.http11.Http11Nio2Protocol" scheme="https" secure="true" SSLEnabled="true" maxThreads="150" server=" " allowTrace="false"> <SSLHostConfig honorCipherOrder="true" certificateVerification="false" sslProtocol="TLSv1.2" protocols="TLSv1.1+TLSv1.2" ciphers="TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384, TLS_ECDH_RSA_WITH_AES_256_GCM_SHA384, TLS_ECDH_ECDSA_WITH_AES_256_GCM_SHA384, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDH_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDH_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDH_RSA_WITH_AES_256_CBC_SHA384, TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA384, TLS_ECDH_RSA_WITH_AES_256_CBC_SHA, TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDH_RSA_WITH_AES_128_CBC_SHA256, TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA256, TLS_ECDH_RSA_WITH_AES_128_CBC_SHA, TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA"> <Certificate certificateKeystoreFile="..\ssl\keystore" certificateKeystorePassword="aBlueSkyMeans0%RainToday" /> </SSLHostConfig> </Connector> So I went back to https://tomcat.apache.org/tomcat-8.5-doc/ssl-howto.html#SSL_and_Tomcat and took a closer look and noticed a couple of things: 1 - My Connector tag config is missing the "sslImplementationName" attribute. 2 - The default ProtocolHandler implementation created by Tomcat from my Connector definition is ["https-openssl-nio2-443"] which is a configuration not mentioned in the doc. It seems the only supported ProtocolHandler implementations are: ["https-jsse-nio-443"] ["https-jsse-nio2-443"] ["https-openssl-nio-443"] When I added the " sslImplementationName" attribute as documented to support one of the above three supported protocols, everything worked fine. My question is this: Can someone tell me for certain whether or not my original Connector configuration (which resulted in the Tomcat creating a default ["https-openssl-nio2-443"] PotocolHandler) *should* work? If this *is* a supported configuration, I would prefer to use it over the other three. Thanks.
