JAVA FULL STACK REFERENCE

  Recently I got a third party generated wsdl, and when I try to use  wsdl2java   cxf-codegen-plugin  in maven eclipse it shows the below error in the wsdl: undefined element declaration 's:schema' After some googling it seems to be a common issue with JAXB and WSDL. Here is the problematic part of the WSDL: <s:element minOccurs="0" maxOccurs="1" name="GetQuoteDataSetResult"> <s:complexType> <s:sequence> <s:element ref="s:schema"/> <s:any/> </s:sequence> </s:complexType> </s:element> The easier solution seems to be to download the WSDL and modify the schema in order to generate the stub.

Tomcat server  1.        Set autoDeploy = false.  This will apply to the /conf/server.xml a.        This addresses an issue where if autoDeploy=true, and there is a failed deploy, DS files get deleted, and prevents hot deploys if war file is prestaged. 2.        Add XX:+HeapDumpOnOutOfMemoryError, -XX:HeapDumpPath= java options. This will apply to /home/tomcat/<JVM_NAME/bin/setenv.sh a.        Produce heapdumps realtime, instead of manually after the fact. 3.        Remove -verbose:gc java option a.        logs duplicate gc logs in Catalina.out Tomcat server needs to restart to effect the above changes.
