[Tomcat, HTTPD, Servlets & JSP] - JSPs with JDK5.0 features do not compile
AstroNox 1 April 2006 22:36:56
Hello everyone,
I'm currently having a problem; in essence, as in the title, is about JSPs with JDK5.0 features that do not compile.
I'm running JBoss 4.0.3 SP1 with the default integrated Tomcat 5.5, with JDK5.0.
I wrote a very simple JSP in Eclipse 3.1.2 with the JBoss IDE 1.5.1 GA, packaged and deployed into JBoss. There is no problem with starting JBoss or deploying the WAR. This is the JSP:
It's just the declaration and definition of a Vector using JDK5.0's generics feature.
However, when I tried to access this JSP through the browser, I get this error:
02:14:15,000 ERROR [[jsp]] Servlet.service() for servlet jsp threw exception | org.apache.jasper.JasperException: Unable to compile class for JSP | | An error occurred at line: 3 in the jsp file: /index.jsp | Generated servlet error: | Syntax error on token "<", invalid AssignmentOperator | | An error occurred at line: 3 in the jsp file: /index.jsp | Generated servlet error: | Syntax error on token "=", != expected | | An error occurred at line: 3 in the jsp file: /index.jsp | Generated servlet error: | Syntax error on token "<", ( expected | | An error occurred at line: 3 in the jsp file: /index.jsp | Generated servlet error: | Syntax error on token "(", invalid Expression | | | at org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:84) | at org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java:328) | at org.apache.jasper.compiler.JDTCompiler.generateClass(JDTCompiler.java:397) | ... etc
Ok, this basically means that the compiler did not recognize the JDK5.0 features. I had already set the following options in Tomcat's conf/web.xml file:
I did search Google for any possible solutions but to no avail. For some reason it seems as if no one encountered it before; either I'm not searching properly or there are no articles on this issue. I did find a thing about Tomcat versions prior to 5.5.16 (this issue was fixed in 5.5.16):
The problem was regarding the compilerSourceVM and compilerTargetVM as mentioned above.
However, I'm very sure that the version of Tomcat that came with JBoss 4.0.3 SP1 is not 5.5.16, although I was unable to find which version was it.
I believe if I were to integrate Tomcat 5.5.16 into JBoss, the issue might be resolved. However I'm unable to find any such tutorial or resource to accomplish this on Google.
Another note is that I'm unwilling to use JBoss 4.0.4 RC1 because there is a bug with EJB3's TransactionManager (yes, I'm using EJB3; RC5 integrated into default server configuration):
Basically I'm stumped. Tried all I can. Can anyone please tell me how to resolve this issue in JBoss 4.0.3 SP1? Please direct me to any existing resolutions, if any. I would also appreciate links to articles that describe how to integrate Tomcat 5.5.x into JBoss. Thanks!
