How to Receiving Rest Calls with Map type Object?

[antonio.giambanco]

Hi all,

a client needs to call my process (start process) trough REST.

Since the message to be sent contains Map type element I would like to understand how I need to configure my process properties in the KIE WB.

Do I need to configure the "Variable Definitions" property with a custom type element?

Thanks

[swiderski.maciej]

you can either declare variable that will be of type map or wrap it with some object. Both should work without an issue.

Hi Maciej Swiderski  

I created my class from the data modeler using all strings and then I edited just two attributes type (List and Map), here my class

package com.objectway.advisory.signature;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

/**

* This class was automatically generated by the data modeler tool.

*/

@org.kie.api.definition.type.Label(value = "InstanceInputData")

public class InstanceInputData implements java.io.Serializable {

    static final long serialVersionUID = 1L;

    @org.kie.api.definition.type.Label(value = "itemId")

    @org.kie.api.definition.type.Position(value = 0)

    private java.lang.String itemId;

    @org.kie.api.definition.type.Label(value = "sourceItemId")

    @org.kie.api.definition.type.Position(value = 1)

    private java.lang.String sourceItemId;

    @org.kie.api.definition.type.Label(value = "userSortType")

    @org.kie.api.definition.type.Position(value = 2)

    private java.lang.String userSortType;

    @org.kie.api.definition.type.Label(value = "provisioningUser")

    @org.kie.api.definition.type.Position(value = 3)

    private java.lang.String provisioningUser;

    @org.kie.api.definition.type.Position(value = 4)

    private java.lang.String checkInDateCEST;

    @org.kie.api.definition.type.Label(value = "checkOutDateCEST")

    @org.kie.api.definition.type.Position(value = 5)

    @org.kie.api.definition.type.Position(value = 6)

    private java.lang.String inputChannel;

    @org.kie.api.definition.type.Label(value = "infos")

    @org.kie.api.definition.type.Position(value = 7)

    private Map<String, Object> infos = new HashMap<String, Object>();

    @org.kie.api.definition.type.Label(value = "users")

    @org.kie.api.definition.type.Position(value = 8)

    private List<String> users;

    public InstanceInputData() {

    }

    public InstanceInputData(java.lang.String itemId, java.lang.String sourceItemId, java.lang.String userSortType, java.lang.String provisioningUser, java.lang.String checkInDateCEST, java.lang.String checkOutDateCEST, java.lang.String inputChannel, java.util.List<String> users, java.util.Map<String, Object> infos) {

        this.userSortType = userSortType;

        this.provisioningUser = provisioningUser;

        this.checkInDateCEST = checkInDateCEST;

        this.checkOutDateCEST = checkOutDateCEST;

        this.inputChannel = inputChannel;

    }

    }

    public void setInputChannel(java.lang.String inputChannel) {

        this.inputChannel = inputChannel;

    }

    public java.lang.String getItemId() {

        return this.itemId;

    }

    public void setItemId(java.lang.String itemId) {

        this.itemId = itemId;

    }

    public java.lang.String getProvisioningUser() {

        return this.provisioningUser;

    }

    public void setProvisioningUser(java.lang.String provisioningUser) {

        this.provisioningUser = provisioningUser;

    }

    public java.lang.String getSourceItemId() {

        return this.sourceItemId;

    }

    public void setSourceItemId(java.lang.String sourceItemId) {

        this.sourceItemId = sourceItemId;

    }

    public java.lang.String getUserSortType() {

        return this.userSortType;

    }

    public void setUserSortType(java.lang.String userSortType) {

        this.userSortType = userSortType;

    }

    public Map<String, Object> getInfos() {

        return infos;

    }

    public void setInfos(Map<String, Object> infos) {

        this.infos = infos;

    }

}

when done I opened my class from data modeler again and here what I see:

I lost attribute Map infos and users attribute is now a string array instead of a List, is it ok?

[swiderski.maciej]

do you mean that you added manually these fields (List and Map) and not via data modeler? If so in 6.1 there was not source code preserving feature in data modeler so such operation is not really supported. You should be able to achieve that in 6.2 tough so go ahead and give it a try with latest CR of 6.2.

Hi Maciej Swiderski

do I need to install again the entire jbpm or I can just deploy the new .war file?

thanks

[swiderski.maciej]

replacing war file should be enough

Hi Maciej Swiderski

Even if I install everything from scratch (with jbpm-installer) the deployment on start.demo fails with this message

"{\"JBAS014671: Failed services\" => {\"jboss.deployment.unit.\\\"jbpm-console.war\\\".WeldStartService\" => \"org.jboss.msc.service.StartException in service jboss.deployment.unit.\\\"jbpm-console.war\\\".WeldStartService: Failed to start service

\"}}"

[swiderski.maciej]

what version are you using? downloaded from?

[antonio.giambanco]

the installer that i tried was 6.2.0 build 4217

jbpm #4217 : /jbpm-distribution/target [Jenkins]

the console war was

kie-wb-distributions #1389 [Jenkins]

and both gave me that error

[swiderski.maciej]

best to rely on CR3 version rather snapshot, so give it a try with war file from this location.

Ok, I deployed jbpm-console, I like so much new features

• I have some problems with old instances still running but not visible now (I can see just task list)
• In the data modeler I don't find Map and List types
• I try to deploy demo processes and I don't see them in the deployed list

[swiderski.maciej]

you need to upgrade your data base, see this script for various dbs scripts.

I did almost everything by deploying from Deploy a New Unit menuu' and now I update with that script

What about Map and List Type?

An other question:

When I launch a Rest request is possible to have a json response instead of a xml one?

if that does not work still please file jira for this

yes, just set Accept header to application/json

Hi Maciej Swiderski    

I take some testes and I will open an issue on jira.

I'm looking for the kie-services-client jar compatible with 6.2cr3 in the previous version I used runtime/kie-services-client-6.1.0.Final.jar (6.1.0 jar doen't work with 6.2)

Did something changend?
