Day to Day Java

Last week I encountered problem that how to get a notification when carbon server throws an error during a long running test or in a production environment. Tailing the log is not practical during these kinds of situations, so I google and found a interesting solution. First you have to install Mailutils package $ sudo apt-get install mailutils Create a file called "notify.sh" and paste the following code in to it. #!/bin/bash EMAILADDRESS="yourmail@gmail.com" EMAILSUBJECT="[Important][CARBON] ERROR OCCURRED" MESSAGEBODY="../repository/logs/errors.txt" cat /dev/null > $MESSAGEBODY SEARCHSTRING='ERROR\|Error\|error\|Exception' SYSLOG=../repository/logs/wso2carbon.log LASTOCCURANCE=`grep -n "$SEARCHSTRING" $SYSLOG | tail -1` LASTLINE=`echo $LASTOCCURANCE | cut -d':' -f1` while true do END=`wc -l $SYSLOG | cut -d' ' -f1` if [ $END -lt $LASTLINE ] then         LASTLINE=$END fi tail -n +$LASTLINE $SYSLOG

When you try to configure SAML2 based Web SSO, did you ever hoped is there an easy way to identify what you have missed or did wrong in either in the Identity Provider (IdP) side or Service Provider (SP) side? Then you should try the SAML Toolkit feature which comes with WSO2 Identity Server 5.0.0 . This toolkit consists of two modules, SAML2 Request Validator - user can validate SP initiated SAML2 AuthnRequest SAML2 Response Builder - user can generate SAML2 response for a selected SAML2 Web SSO configuration Lets try this tool, First you need to download the WSO2 Identity Server 5.0.0 and follow the "Getting Started" section to run the product. If you have followed the instructions correctly you should be able to access the server using the URL https://localhost:9443/carbon. Once you have logged to the server, you can find the required tools under Main > Tools > SAML .   Figure 1: SAML Toolkit Section SAML Request Validator Once

A resent performance study ESB Performance Round 7.5 shows that WSO2 ESB 4.8.1 outperforms all other open-source ESBs and keeps them in the dust as usual.
