Exception Starting roo project from mvn tomcat:run

[nyronian]

I get the following exception when running mvn tomcat:run from the command line. The project runs fine inside the Springsource Tool Suite. I MUST be missing some jars or different versions of jars or something but I don't know what.

Any thoughts or ideas would be most helpful. thank you very much!

Wild guess, but those filters do extend that class, so I'd say you have a couple of the j2ee.jar on your classpath. Your app server should be providing it, so if it is in your WEB-INF/lib then you want to remove it. (and make sure you clean the file from the app server deployment). It might have a different name depending on where it came from in the first place, but should be recognisable.

Given this is coming from mvn tomcat:run, you might want to try mvn -up tomcat:run to update your Maven plugins.

Hey ben,

I am also facing the same issue stated above

ERROR org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.xml.XmlBeanDefin itionStoreException: Line 56 in XML document from file D:\roooo\target\classes\META-INF\spring\applicationContext.xml is invalid; nested exception is org.xml.sax.SAXParseException: The content of elements must consist of well-formed character data or markup.

I tried doing a mvn -up tomcat:run but still I face the same issue.. Will be great if you can reply back on this..

Thanks and Regards
Naveen

If I run the application from eclipse or I do a mvn tomcat:deploy to a running instance of tomcat I do not see the issue.

If I simply do mvn tomcat:run (which, as I understand it, uses an instance of tomcat under mavens control) it gives the error. Very odd.

As a work around, I just run it from eclipse or deploy to my on tomcat server.

@Nyronian, thanks for sharing your workaround. Roo just uses the Maven Tomcat plugin, we didn't write it. I see on 5 May 2010 1.0 was released on tomcat-maven-plugin, so maybe you might try editing your pom.xml to change the version from 1.0-beta-1 to 1.0? http://repo2.maven.org/maven2/org/co...en-plugin/1.0/

If that works, would you mind logging a Jira ticket at http://jira.springframework.org/browse/ROO to remind us to upgrade the plugin version? Thanks

Hi @Nyronian and @Ben,

I had the same issue recently and the 1.0. tomcat plugin upgrade did not help.

First I found that while the 'mvn tomtom:run-war' works fine the dynamic 'mvn tomtom:run' fails with the above mentioned exceptions.

Then by analyzing my pom dependency hierarchy I discovered a jetty:6.1.22 dependency that implicitly imports the servlet-api:2.5-20081211. I filtered out the later by adding an exclusion clause:

   <dependency>
      <groupId>org.mortbay.jetty</groupId>
      <artifactId>jetty</artifactId>
      <version>6.1.22</version>
      <type>jar</type>
      <scope>compile</scope>
      <exclusions>
         <exclusion>
            <groupId>org.mortbay.jetty</groupId>
            <artifactId>servlet-api</artifactId>
         </exclusion>
      </exclusions>
   </dependency>

which solved the problem for me.

Hope this will help,
Cheers, Chris

Hello,

In my case, the Apache POI library was implicitly importing the javax.servlet:servlet-api:jar:2.3 into my dependency tree.

I found this out analysing the dependency tree with mvn dependency:tree and then rectified the problem by adding an exclusion as mentioned in the above post under the poi dependency.

I solved the problem thanks to this thread, just wanted to thank you folks. :-)

Cheers,

got same exception:

SEVERE: Exception starting filter Spring OpenEntityManagerInViewFilter
java.lang.ClassCastException: org.springframework.orm.jpa.support.OpenEntityMana gerInViewFilter cannot be cast to javax.servlet.Filter
....

Searched for servlet ad dependency but there is no thing like servlet-api (only tiles servlet, and jsp servlet).

I tried reverting to older version of project (which was working for sure), but still get this error!

HELP PLEASE!

EDIT: ok. got it working!

I used some patch to render velocity with tiles and it used JspFactory from javax.servlet.jsp.JspFactory
after removing few lines of code all is working!

Hi folks,

I'm now getting this error, but only after I add CXF as a dependency. As noted before, if I run this as "mvn tomcat:run-war" everything is fine, but not when I run "mvn tomcat:run" so I'm a bit lost. the servlet-api is only listed once as provided, and when I comment that out, "mvn tomcat:run" still fails with the same error.
