    Examples not working (in a few releases) and no examples in Alpha 3

    Tony Herstell Master

      Downloaded examples for 2.8 (and 2.7) and found the run.cmd contains what appears to be mergelines from some source system.

       

      <<<<<<< HEAD java -Djava.ext.dirs=./lib -cp modeshape-example-sequencers-0.5-SNAPSHOT.jar org.modeshape.example.sequencer.SequencingClient %* ======= java -Dlogback.configurationFile=logback.xml -Djava.ext.dirs=./lib -cp modeshape-example-sequencers-0.5-SNAPSHOT.jar org.modeshape.example.sequencer.SequencingClient %* >>>>>>> 8b3f7f3... Using Logback configuration file.

       

      It also refers to modeshape-example-sequencers-0.5-SNAPSHOT.jar; but it stall ran (even when renamed to the proper jar).

       

      Hacked the file and to get the run.cmd running and ran the sequencers example.

       

      Uploaded file, but then cound not do much else as got a secuirty problem reported (stack trace).

       

       

      Please enter the file to upload: caution.gif Please enter the repository path where the file should be placed [/a/b/caution.g if]: javax.jcr.LoginException: Unable to create session for workspace default in repo sitory content: authentication failed. Check credentials.         at org.modeshape.jcr.JcrRepository.login(JcrRepository.java:1476)         at org.modeshape.example.sequencer.SequencingClient.createSession(Sequen cingClient.java:571)         at org.modeshape.example.sequencer.SequencingClient.uploadFile(Sequencin gClient.java:221)         at org.modeshape.example.sequencer.ConsoleInput$1.run(ConsoleInput.java: 69)         at java.lang.Thread.run(Unknown Source)

       

      Looked through example source code (examples\sequencers\src\main\java\org\modeshape\example\sequencer) and found hardcoded private secuirty for USERNAME (jsmith) and PASSWORD (secret) but these don't seem to be used in any of the example code.

       

      No examples for Alpha3; but it is an Alpha.

       

      ...

       

      Had problems even getting ModeShape running using the "getting started' documentation and that is why I reverted to the examples. I will persever with using the example code for 2.8.

          Yikes! The 'run.cmd' and 'run.sh' are both quite messed up.

           

          Try editing the run.cmd file and replacing it all with this:

           

               java -Dlogback.configurationFile=logback.xml -Djava.ext.dirs=./lib -cp modeshape-example-sequencers-2.8.1.Final.jar org.modeshape.example.sequencer.SequencingClient %*

           

          I hope that works. (I don't have windows and can't verify that it's correct.)

           

          I presume you used the examples as-is? I'll try to run them tomorrow and see what's going on.

          • 2. Re: Examples not working (in a few releases) and no examples in Alpha 3
            Tony Herstell Master

            I got it running with

             

            java -Dlogback.configurationFile=logback.xml -Djava.ext.dirs=./lib -cp modeshape-example-sequencers-2.8.0.Final.jar org.modeshape.example.sequencer.SequencingClient %*

             

            Looks same as yours.

             

            However, still fails with secuirty...

             

            The exmaple code does not seem to use the args.

              I believe the documentation (getting started) refers to

               

              ... JSP page

              <%!

              static {

                  // Initialize IDTrust

                  IDTrustConfiguration idtrustConfig = new IDTrustConfiguration();

                  try {

                      idtrustConfig.config("security/jaas.conf.xml");

                  } catch (Exception ex) {

                      throw new IllegalStateException(ex);

                  }

              }

              %>

               

               

              and IDTrustConfiguration, from Picketbox, has been is not there (supercceded) in 3.0.0.Final and the exmaple code is out of date.

                This certainly points to picketbox being the newkid on the block and the getting started doc being out of date:

                  I have moved to 3Alpha6, on JBoss 7.1.1.Final, and got it working quickly.

                   

                  I have setup Jboss to use 3Alpha6 and it works fine once I figured that the -c standalone-modeshape.xml option will run the standalone-modeshape.xml and thus not the normal one; so all my changes to the default standalone.xml files need to be copied into standalone-modeshape.xml (DOH!).

                   

                  I am working thriough some examples, and optomistically just added the following maven:

                          <dependency>

                              <groupId>org.modeshape</groupId>

                              <artifactId>modeshape-jcr</artifactId>

                              <version>3.0.0.Alpha6</version>

                            </dependency>       

                          <dependency>

                              <groupId>javax.jcr</groupId>

                              <artifactId>jcr</artifactId>

                              <version>2.0</version>

                          </dependency>

                   

                  I also added the maven includes and changed them to 3.0.0.Alpha6.

                  e.g.

                  <dependency>

                    <groupId>org.modeshape</groupId>

                    <artifactId>modeshape-sequencer-ddl</artifactId>

                    <version>3.0.0.Alpha6</version>

                  </dependency>

                  ...

                   

                  Now; I am after putting a file into a repository on the filesystem, and reading it back, and have looked at various examples, for various versions of the project and even JackRabbit.

                   

                  Your work is much appreciated and great to see the progress (including having WebDav back).

                   

                  Another "feature" was that if your server crashed out during runup (happens quite a lot when trying to guess modeshape setup in the server config files), it can take out the dodeploy file by replacing it with .failed for the modeshape files. This requires you to manyually rename the files back to .dodeploy

                   

                  Will there be a small piece on how to run this up under Tomcat as well as this is required...

                    Great. BTW, if you've not found our (still incomplete) 3.0 documentation, check out the page that talks about how to install ModeShape into AS7., where we talk about the "standalone-modeshape.xml" file.

                    That should work just fine. We also have a Git repository with several 3.0-related examples, and the current code contains the Maven dependencies on Alpha6. See that page for instructions on how to get, build, and run the examples.

                    Yes, we're getting close to having all the features finished!

                    I agree that you can easily get into a rough state if you don't start AS7 correctly, but I'm not sure how we can make this easier. Perhaps the easiest is to use the AS7 console, which should show that these failed deployment and allow you to re-deploy them. If you have any ideas, please let us know.

                     

                    Will there be a small piece on how to run this up under Tomcat as well as this is required...

                     

                    Yes, we have a mostly-empty page in our documentation right now.

                      Humm.. perhaps adding a file in there (.bat/.sh) that you just run to rename the files back to .dodeploy? at least its just one click!

                       

                      Its odd that AS 7 renames all the files to failed; when it was only 1 file (war) that failed to deploy so you might mention that to the AS team as they might have a good reason for doing that.

                        I also cloned the modeshape-examples and used the sequencer example as template to play with.

                         

                        For a AS 7 install I had to search for /files/apiary-manager-logo-tall.png as opposed to /images/apiary-manager-logo-tall.png... and not sure why.

                         

                         

                                   try {

                                        tools.uploadFile(session, "/files/apiary-manager-logo-tall.png", getFile("apiary-manager-logo-tall.png"));

                         

                                        // Save the session ...

                                        session.save();

                         

                                        Node apng;

                                        try {

                                            apng = findNodeAndWait(session, "/files/apiary-manager-logo-tall.png", 10, TimeUnit.SECONDS);

                                            if (print) {

                                                tools.printSubgraph(apng);

                                            }

                                        }

                                        catch (InterruptedException e) {

                                            // TODO Auto-generated catch block

                                            e.printStackTrace();

                                        }

                         

                        looking in the AS 7 standalone.modeshape.xml I see:

                                            <sequencer name="cnd-sequencer" classname="cnd" path-expression="default:/files(//*.cnd[*])/jcr:content[@jcr:data] => /derived/cnd/$1"/>

                                            <sequencer name="xsd-sequencer" classname="xsd" path-expression="/files(//*).xsd[*]/jcr:content[@jcr:data] => /derived/xsd/$1"/>

                                            <sequencer name="wsdl-sequencer" classname="wsdl" path-expression="/files(//)*.wsdl[*]/jcr:content[@jcr:data] => /derived/wsdl/$1"/>

                                            <sequencer name="xml-sequencer" classname="xml" path-expression="/files(//)*.xml[*]/jcr:content[@jcr:data] => /derived/xml/$1"/>

                                            <sequencer name="zip-sequencer" classname="zip" path-expression="/files(//*.zip[*])/jcr:content[@jcr:data] => /derived/zip/$1"/>

                                            <sequencer name="image-sequencer" classname="image" path-expression="/files(//*.(png|jpg|gif)[*])/jcr:content[@jcr:data] => /derived/image/$1"/>

                                            <sequencer name="mp3-sequencer" classname="mp3" path-expression="/files(//*.mp3[*])/jcr:content[@jcr:data] => /derived/mp3/$1"/>

                         

                        I was alittle confused as the sequencers above those lines have "proper" class names like org.modeshape.sequencer.classfile.ClassFileSequencer

                         

                        I wonder if this is connected to my issue above.

                         

                        I am still looking forward to an example that shows how to back onto a file system so you can go look at the filesystem files.

                         

                        I also found that when I did unzip into AS7 and then ran through all the commands in the "install in AS 7" tutorial they all said it was already done; perhaps I misunderstood as it may have been Unzip OR run all those commands from CLI. Also the examples that go with the AS7 simpel install now seem different from the modeshap-examples :/

                         

                        Great Progress though....

                            On another note:

                            >> Configure your webdav server to use Digest Authentication. Windows 7 WILL NOT connect to webdav servers using Basic Authentication.

                             

                            It seems W7 will not connect unless we use Digest Authentication.

                             

                            Therefore, when I try to map a network drive on W7 it fails to connect and assume this is the reason.

                                      return this.repository.login(credentials, workspaceName);

                               

                                  }

                               

                               

                              then execute mvn clean install again.
