You need to merge the entire web tier compiler WAR with your existing WAR. If you just move random jars over chances are good you'll miss some dependencies.

Well the problem is that, although I have included the flex-bootstrap.jar, flex-bootstrap-jsp.jar, flex-webtier.jar and flex-webtier-jsp.jar I always receive the same exception in the explorer or mozilla navigator: java.lang.NullPointerException flex.bootstrap.BootstrapTag.<init>(BootstrapTag.java:24) flex.bootstrap.BootstrapBodyTag.<init>(BootstrapBodyTag.java:14) flex.webtier.server.j2ee.jsp.MxmlTagImpl.<init>(MxmlTagImpl.java:2) I am using Tomcat 6 server and I receive always the following trace: EVERE: Servlet.service() for servlet jsp threw exception org.apache.jasper.JasperException: Unable to read TLD "META-INF/taglib.tld" from JAR file "file:/C:/google2/MapasOpodo/build/web/WEB-INF/lib/flex-bootstrap.jar": java.lang.NullPointerException at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:51) at org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:409) at org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:181) at org.apache.jasper.compiler.TagLibraryInfoImpl.<init>(TagLibraryInfoImpl.java:182) at org.apache.jasper.compiler.Parser.parseTaglibDirective(Parser.java:420) ... ... ...

I am so sorry for having to find help, but I have lost all the day of work today, and if you could help me... Many Thanks David Virgil.
