Chris,

Thanks very much for your quick response and feature enhancement. It works great!

 

I did discover what looks like a bug in the grouperClient display from the line command. Some of the data is mixed up. The displayName field shows data for display extension, and the extension field shows the last node of the group name, even though I intentionally set the extension to a different value as a test.

 

Program code:

      wsGroup.setName("NAU:group name");

      wsGroup.setDisplayName("NAU:group display name");

      wsGroup.setExtension("group extension");

      wsGroup.setDisplayExtension("group display extension");

      wsGroup.setDescription("group description");

 

      wsGroupToSave.setSaveMode("INSERT");

      wsGroupSaveResults = gcGroupSave.execute();

 

grouper.client.properties:

webService.findGroups.output = Index ${index}: name: ${wsGroup.name}, displayName: ${wsGroup.display

Name}, extension: ${wsGroup.extension}, displayExtension: ${wsGroup.displayExtension}, description:

${wsGroup.description}$newline$

 

java -jar grouperClient.jar --operation=findGroupsWs --queryFilterType=FIND_BY_STEM_NAME --stemName=NAU

 

Index 0: name: NAU:group name, displayName: NAU:group display extension, extension: group name, displayExtension: group display extension, description: group description

I made some improvements to the 1.4 branch to address your issues:

 

https://bugs.internet2.edu/jira/browse/GRP-230

 

1. If there is no lookup object on an insert, it should be ok

2. If there is a lookup, with a name, on an insert, and the name is the same as the group name (nonlookup), then thats ok

3. If an insert, and the group already exists, then give the error GROUP_ALREADY_EXISTS

 

Get 1.4 branch with:

 

cvs -d:pserver::/home/cvs/i2mi login

cvs -d:pserver::/home/cvs/i2mi export -r GROUPER_1_4_BRANCH grouper

cvs -d:pserver::/home/cvs/i2mi export -r GROUPER_1_4_BRANCH grouper-ws

 

Regards,

Chris

Chris,

A special response code would be ideal, since the INSERT saveMode implies that you are counting on the group not existing yet. However, I can analyze the error message for a phrase if necessary, but the problem I am having is that I do not get “group already exists with name:” anywhere in my error message. You show this:

 

Bad response from web service: resultCode: PROBLEM_SAVING_GROUPS, There were 0 successes and 1 failures of saving groups.  

java.lang.RuntimeException: edu.internet2.middleware.grouper.exception.GroupAddException: group already exists with name: 'aStem:aGroup4',

 

What I get is this:

"Bad response from web service: resultCode: PROBLEM_SAVING_GROUPS, There were 0 successes and 1 failures of saving groups.

java.lang.RuntimeException: java.lang.RuntimeException: Must not pass in a name for an insert,

Problem in HibernateSession: HibernateSession: isNew: false, isReadonly: false, grouperTransactionType: READ_WRITE_NEW,

Problem in HibernateSession: HibernateSession: isNew: true, isReadonly: false, grouperTransactionType: READ_WRITE_NEW

          at edu.internet2.middleware.grouper.ws.soap.WsGroupToSave.save(WsGroupToSave.java:365)

Sorry, this email slipped by me.  I run this from grouper client API

 

  public static void main(String[] args) {

    WsGroupToSave wsGroupToSave = new WsGroupToSave();

    wsGroupToSave.setSaveMode("INSERT");

    wsGroupToSave.setWsGroupLookup(new WsGroupLookup(null, null));

    WsGroup wsGroup = new WsGroup();

    wsGroup.setDisplayExtension("a group4");

    wsGroup.setExtension("aGroup4");

    wsGroup.setName("aStem:aGroup4");

    wsGroupToSave.setWsGroup(wsGroup);

    try {

      WsGroupSaveResults wsGroupSaveResults = new GcGroupSave().addGroupToSave(wsGroupToSave).execute();

      //prints SUCCESS_INSERTED when it works

      System.out.println(wsGroupSaveResults.getResults()[0].getResultMetadata().getResultCode());

    } catch (GcWebServiceError gwse) {

      WsGroupSaveResults wsGroupSaveResults = (WsGroupSaveResults)gwse.getContainerResponseObject();

      System.out.println(wsGroupSaveResults.getResults()[0].getResultMetadata().getResultCode());

     

      gwse.printStackTrace();

    }

  }

 

When it is not there, it prints: SUCCESS_INSERTED

 

When it is there, it prints:

 

edu.internet2.middleware.grouperClient.ws.GcWebServiceError: Bad response from web service: resultCode: PROBLEM_SAVING_GROUPS, There were 0 successes and 1 failures of saving groups.  

java.lang.RuntimeException: edu.internet2.middleware.grouper.exception.GroupAddException: group already exists with name: 'aStem:aGroup4',

 

 

Here are the possible response codes to a group save:

 

http://viewvc.internet2.edu/viewvc.py/grouper-ws/grouper-ws/doc/api/edu/internet2/middleware/grouper/ws/soap/WsGroupSaveResult.WsGroupSaveResultCode.html?root=I2MI&view=co

 

 

Do you want a special response code for an insert that indicates the group was already there, or is EXCEPTION good enough?

 

Thanks,

Chris

Hi Chris.

Thanks for the great help on how to access web services from within a java program. Your example worked great. I am now venturing out and trying to do a GroupSave using the GrouperClient.java code as a guide. The save operation works, but if I try to save a group name that already exists and get an error message, I want to be able to determine that the error was due to the group already existing rather than some other reason. I have been unable to determine this from the error message that is returned.

 

I set saveMode = "INSERT" because I do not want to modify an existing group if it exists. If the group already exists, I get this error message:

Grouper error attempting to save group. edu.internet2.middleware.grouperClient.ws.GcWebServiceError: Bad response from web service: resultCode: PROBLEM_SAVING_GROUPS, There were 0 successes and 1 failures of saving groups.  

java.lang.RuntimeException: java.lang.RuntimeException: Must not pass in a name for an insert,

Problem in HibernateSession: HibernateSession: isNew: false, isReadonly: false, grouperTransactionType: READ_WRITE_NEW,

Problem in HibernateSession: HibernateSession: isNew: true, isReadonly: false, grouperTransactionType: READ_WRITE_NEW

 

I do not see anything in the error message that tells me the group already exists. e.getMessage() does not give me any different information.

 

Is there a way I can tell if the GroupSave failure is due to the group already existing?

 

Thanks.

Paul Gazda

I think the easiest and best way to use grouper web services by code is to use the grouper client API.  Here is an example below that I tested and it works.  All the configuration is in the grouper.client.properties file, and you only need the grouperClient.jar.  Here are the classes you should be using:

 

http://middleware.internet2.edu/dir/groups/grouper/grouper/1.4.1/gc/api/edu/internet2/middleware/grouperClient/api/package-summary.html

 

Here are all the underlying beans:

http://middleware.internet2.edu/dir/groups/grouper/grouper/1.4.1/gc/api/edu/internet2/middleware/grouperClient/ws/beans/package-summary.html

 

 

Full javadoc:

http://middleware.internet2.edu/dir/groups/grouper/grouper/1.4.1/gc/api/index.html

 

Here are example grouper client calls:

http://viewvc.internet2.edu/viewvc.py/grouper-misc/grouperClient/src/java/edu/internet2/middleware/grouperClient/GrouperClient.java?root=I2MI&view=markup

 

That said, I need to put more examples on the grouper client website, if you need help doing something, let me know and I can beef up the docs.

 

Your other code either needs all the dependent jars, or to use the classes in the classpath of the grouperClient.jar.  I took in a minimal number of 3^rd party jars into the grouper client jar, and changed their classpath so nothing conflicts.  I wanted this to be very easy for non java people to use, so it is one jar and one config file, and an easy command line.  Java is not as easy to kick off with multiple jars, and less easy to upgrade etc…  there are disadvantages here (like your confusion), but I think the pros outweigh the cons.

 

Regards,

Chris
