Catania Science Gateway Framework / Discussion / General Discussion: compilation of mi-portlets

Liam Thompson - 2013-08-01

Hi everyone

This is a basic, possibly silly question, but I am spending alot of time trying to figure this out and I'm not making progress.

When I compile any of the mi-portlets from the SVN repo, I get for mi-hostname-portlet
''The import it.infn.ct.GridEngine.JobCollection cannot be resolved'' and for mi-hostname-portlet I get ''The import it.infn.ct.GridEngine.JobResubmission cannot be resolved''.

Now obviously, as the error says, the compile process is missing the components from the GridEngine. I am able to get the portlets to build in Eclipse, but I can't seem to get it to work on the command line. Do you have a suggestion for me please ?

Thanks
Liam

  Hi Liam,
  
  Accordingly to the mi-hostname-portlet extracted form SVN Rev.537 there is no:
  
  import it.infn.ct.GridEngine.JobCollection
  
  Maybe you are mentioning another portlet code?

Hi Riccardo

Sorry, I should have been more specific. I confirm the repo revision 537.

for portlets/mi-hostname-portlet, using ''ant test'', I get The import it.infn.ct.GridEngine.JobResubmission cannot be resolved.

for portlets//mi-parallel-app-portlet, using ''ant test'', I get The import it.infn.ct.GridEngine.JobCollection cannot be resolved.

Like I said in the previous email, it works in Eclipse, but not with ant. I'm not sure how to include these dependencies in the build.xml file, or whether I need to include something extra in the build path or some other config setting.

Thanks

  Hi Riccardo
  
  I tried to use Netbeans and Ant to compile and build the project, but it gave me so many errors (like above), that I went back to Eclipse, and built it successfully from there.
  
  I don't know why it won't compile using Ant (in command line) or Netbeans.

  Liam,
  
  If you have troubles with the import statements you probably have misconfigured the portlet.xml file.
  Could you please check that you have the following files the statements:
  
  1)
  $LIFERAY_SDK/build-common.xml
  ...
  <path id="lib.classpath">
  <fileset dir="${project.dir}/lib" includes="*.jar">
  <fileset dir="/opt/GridEngine/lib" includes="*.jar">
  </fileset></fileset></path>
  ...
  
  This is the most important file that informs ant to watch for GridEngine libraries
  
  2)
  $LIFERAY_SDK/portlets/mi-hostname-portlet/docroot/WEB-INF/glassfish-web.xml
  ...
  <class-loader delegate="true" extra-class-path="/opt/GridEngine/lib/hibernate3.jar ... (a ':' separated list of jars you can obtain executing the (*) command)
  ...
  
  () find /opt/GridEngine/lib -name '.jar' (see the customize.sh script for more information)
  
  Could you please check and let me know,
  Regards,

    Hi Riccardo
    
    Was there supposed to be something pasted below $LIFERAY_SDK/build-common.xml ?
    
    The confusing part for me is that I can build the portlet with Eclipse. Does that mean Eclipse is better at finding all the extra bits that need to go with a particular project that Netbeans is ?

      Liam,
      
      I noticed that some part of my reply was wrong on my Mail Client Sent folder.
      Inside the $LIFERAY_SDK/build-common.xml
      
      you must have the following:
      
      <path id="plugin.classpath"> <path refid="plugin-lib.classpath" /> <fileset dir="${app.server.lib.global.dir}" includes="*.jar" /> <fileset dir="${app.server.lib.portal.dir}" includes="annotations.jar,commons-logging.jar,log4j.jar,util-bridges.jar,util-java.jar,util-taglib.jar" /> <fileset dir="${project.dir}/lib" includes="activation.jar,jsp-api.jar,mail.jar,servlet-api.jar" /> <fileset dir="/opt/GridEngine/lib" includes="*.jar" /> </path>
      
      I personally dislike to work with Eclipse or Netbeans for so small projects like the hostname. I also intentionally followed that approach to avoid new users to deal with specific platform issues. For this reason I'm just using what the LIFERAY SDK provides.

        Hi Riccardo
        
        Thanks for the correction. Whilst I agree with you on using
        Eclipse/Netbeans for such a small project, I am quite new to this, so I
        thought it might be helpful.
        
        I will try those configuration settings and see if they make a different
        to the build and deployment.

        Hi Riccardo
        
        It's not quite working yet, although I feel like I'm close to getting
        the portlet to compile on both my computer and the server using ant. The
        number of errors I get when trying to build is much reduced.
        
        I did a comparison of the build-common.xml and glassfish-web.xml files
        on the SVN, and they are both identical to what I have, so that is not
        the problem.
        
        I've removed the general bash classpath from both machines, as the Ant
        manual says not to use it (I've also tried building with -noclasspath),
        it didn't seem to make any difference.
        
        I deleted and re-loaded the GridEngine libraries (one file was corrupt),
        but that didn't fix everything.
        
        I've made sure of my JAVA_HOME and ANT_HOME directories, and have run
        ant -v and ant -d, but I see nothing obviously wrong. Further 'javac' is
        pointing to /usr/lib/jvm/java-1.7.0-openjdk.x86_64/bin/javac.
        
        I've tried a different ant.build.javac.source=1.5/1.6/1.7 in the
        build.user.properties file, but that doesn't seem to matter
        
        I have attached the output from the compilations of the
        mi-hostname-portlet, on which I ran customise.sh (without making changes),
        
        I hope with your expert eye (or somebody elses), you might see something
        I don't.
        
        Thanks
        Liam

Hi everyone

In frustration, I delete the Liferay SDK directory, and recreated it using the zip file. I created a fresh customisation from mi-hostname-portlet -->

it compiled fine on my computer, and I was able to build a war file.

it did not compile on the server and I received only 1 error below. The slight differences between the environments will drive me insane.

/opt/liferay-plugins-sdk-6.1.1/portlets/mi-custom-portlet/docroot/WEB-INF/src/it/infn/ct/mi_custom_portlet.java:1416: error: cannot find symbol
[javac] jobDesc.setOutputFiles(outputSandbox); // Setup output files (OutputSandbox) (*)
[javac] ^
[javac] symbol: method setOutputFiles(String)
[javac] location: variable jobDesc of type GEJobDescription
[javac] 1 error

Any ideas, or is this another configuration issue ?

Thanks
Liam

Hi everyone

You can ignore my previous post, the portlet, whilst it builds on my computer, does not deploy on my computer/server giving many of the same errors as "The import it.infn.ct.GridEngine cannot be resolved", "MultiInfrastructureJobSubmission cannot be resolved to a type" and "GEJobDescription cannot be resolved to a type" when I try to deploy it.

Perhaps someone could send me a portlet.xml file or build.user.properties or glassfish-web.xml files so I can see where I am going wrong.

Thanks
Liam

Hi everyone

I managed to fix the problem. The NoMethodError seems to be a problem between versions of libraries between compile and runtime. Hence the portlet was compiling fine on my computer, but no running properly on the server, which had not been updated to the libraries I had on my PC. Now that I've updated them, the problem is fixed
