>> I heard Tomcat 5.5.17runs internally on JDK 1.5. Not quite correct. If you just get the core Tomcat 5.5.x download, it expects to run in a Java 1.5 environment. However on the same page you download the Core Tomcat package from ... http://tomcat.apache.org/download-55.cgi There is a "JDK 1.4 Compatability Package" download that lets it run must fine on Java 1.4.
That said, most webapps developed under Java 1.4.2 run just fine under Java 1.5.x. Out of a half-dozen webapps I have migrated, only one needed any change at all - for that one I had to change a variable name, IIRC I was using "enum" which is a new type in Java 1.5. Try it - Java 1.5 will give you a whole new set of language capabilities. I did not use them really at first, but within a year considered them indispensable.

Hi, My web application was developed against JDK 1.4.2. I heard Tomcat 5.5.17runs internally on JDK 1.5. Is it a problem to deploy my webapp on Tomcat 5.5.17? Or can webapps developed under jdk 1.4.2 run fine unchanged on Tomcat 5.5.17? --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
