tomcat in unix server issues

[shashank beerla]

Hi everyone

I am using tomcat version 6 in the unix server. When I try to run the sh version.sh file I get an error saying bad version. bin/bootstrap is not working i believe. I checked the jdk and jre version . They are compatible . I used commands java -version and javac -version to check the compatibility of java and compiler version.

Recently I developed an application using GWT framework. When I deploy the application on the local tomcat server it wrks greats in the windows. I am using jdk 1.7 and jre7 in my local and verified on both tomcat version 6 & 7. The application worked great and have no issues. I used ANT script to package the application so to deploy on unix server. I used the same ANT script to build the package when I deployed on local tomcat.

Can anyone suggest what exactly could have gone wrong. Based on the error I understand compiler is not compatible to java version. When I run the sh version.sh in unix it showed the JRE HOME variable as /usr folder. I found in that folder java and jre compatible. Please help . Thanks

Please post the output from version.sh. This what I see with my setup - running Tomcat 7, JDK 6u17, Centos 6.

JRE_HOME=/usr indicates that you are using the open-source Java to run Tomcat instead of one of the commercial JDKs available from Oracle or Sun.

I'm afraid that the open-source Java isn't fully functional. Your best bet would be to download and install a Sun/Oracle JDK and setup your Tomcat start process to have the environment variable JAVA_HOME point to that JDK.
