Fosstrak webadapter with Tomcat 8

[djbur...@gmail.com]

Hi,

I'm running Windows 7 64-bit, with Tomcat 8.0.22 (64-bit Windows zip), MySQL Connector/J v5.1.35, and MySQL 5.6.17.

I've set up a Fosstrak repository (0.5.0), and, so far, everything is working in that I can upload events via the capture interface, and retrieve them via the query interface.

I'm now trying to add the webadapter, following the instructions in https://code.google.com/p/fosstrak/wiki/EpcisWebadapterGuide

I can get to the page http://localhost:8080/epcis-webadapter-0.1.0/rest/1/config/epcisurl and change the instance to http://localhost:8080/epcis-repository-0.5.0

However, when I try to go to http://localhost:8080/epcis-webadapter-0.1.0/ i get the following error:

"org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: [63] in the generated java file: [C:\temp\apache-tomcat-8.0.22\work\Catalina\localhost\epcis-webadapter-0.1.0\org\apache\jsp\index_jsp.java]

    javax.servlet.http.HttpServlet.service(HttpServlet.java:729)
    org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)"

Has anyone else had experience of this?

From google ( http://stackoverflow.com/questions/26436463/getdispatchertype-is-undefined-for-the-type-httpservletrequest ), it seems that it's something to do with a conflicting servlet-api version? the recommendation is to change:

<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>servlet-api</artifactId>
  <version>2.5</version>
</dependency

to:

<dependency>
   <groupId>javax.servlet</groupId>
   <artifactId>javax.servlet-api</artifactId>
   <version>3.1.0</version>
</dependency>

However, where would I do this? there are a couple of possible candidate pom.xml files:

<apache-tomcat-8.0.22>\temp\0-epcis-repository-0.5.0\META-INF\maven\org.fosstrak.epcis\epcis-repository\pom.xml
<apache-tomcat-8.0.22>\webapps\epcis-repository-0.5.0\META-INF\maven\org.fosstrak.epcis\epcis-repository\pom.xml

Should I change either of them? both of them? none of them? apparently these files are something to do with something called maven... I'm not running anything fancy on here, just a plain jdk - is maven something that gets bundled with tomcat?

Alternatively, should I just go back to Tomcat 7.x?

Thanks for any pointers!
Dave

As a follow-on, I've now tested under Tomcat 8.0.23 (the latest version) and it still doesn't work. However, going back to Tomcat 7.0.62, it *does* work...!

Hi, 

I haven't tested it lately but my old memories remind me of simply removing the servlet-api jar from epcis Web-inf/lib directory and restarting tomcat. 

Best regards,
