"Error - found in negative cache" for Component.js

[Former Member]

Hi Experts,

I've created my own sandbox in Eclipse to test and extend Standard Fiori apps.

I've downloaden and uploaded a standard Fiori app (CRM_MYCONT) to my Eclipse workspace.

After that, I did the appconfig, the configuration of the proxy and the installation of the tomcatserver.

This all works fine.

So when I go to:

http://localhost:8080/CRM_MYCONT/test-resources/sap/ushell/shells/sandbox/fioriSandbox.html

I can see my Fiori luanchpad, with the CRM_MYCONT app:

When I click on the tile, I get the message that the app doesn't work:

In the javaconsole:

It looks like the Component.js can not be found.

But:

it's there...

What can be the problem?

Hi Andy,

Your appconfig should look like below

{

"applications" : {

            "<semantic object>-<action>" : {

                "additionalInformation" : "SAPUI5.Component=<your application namespace>",

                "applicationType" : "URL",

                "url" : "/<Eclipse project>",

                "description" : "<app description>"

            }

    }

}

And if your app is using an odata service and not mock data, then try defining service uRL in your component.js as below. Also define a function for your getServiceURL like below. I had initially faced a lot of challenges to setup my App on Launchpad sandbox.

                serviceUrl : URI(

                    getServiceUrl("/sap/opu/odata/sap/<whatever>/"))

               }

function getServiceUrl(sServiceUrl) {

  // for local testing prefix with proxy

  // if you and your team use a special host name or IP like 127.0.0.1 for

  // localhost please adapt the if statement below

  if (window.location.hostname == "localhost") {

    var str = window.location.pathname;

    var patt = new RegExp(

        "test-resources/sap/ushell/shells/sandbox/fioriSandbox.html");

    if (patt.test(str)) {

      return "../../../../../" + "proxy" + sServiceUrl;

    } else {

      return "proxy" + sServiceUrl;

    }

  } else {

    return sServiceUrl;

  }

}

Hi Mathew,

I don't think it has someting to do with the proxy.

This is the error I get:

Looks like there is an issue with your file structure. Can you please send me screenshot of your Webcontent folder in your extension project. You previously sent a similar one for the standard app.

Hi Mathew,

I found the problem...

I moved the files:

Component-dbg.js

Component-preload-dbg.js

Component-preload.js

Component.js

Configuration-dbg.js

Configuration.js

index.html

Main-dbg.controller.js

Main.controller.js

Main.view.xml

version.json

to the WebContent folder.

And now it's working

Hi Mathew,

Now I get  the message that the OData call failes...

I added this in the web.xml file:

<!-- ============================================================== -->
  <!-- UI5 proxy servlet                                              -->
  <!-- ============================================================== -->


  <servlet>
  <servlet-name>SimpleProxyServlet</servlet-name>
  <servlet-class>com.sap.ui5.proxy.SimpleProxyServlet</servlet-class>
  </servlet>
  <servlet-mapping>
  <servlet-name>SimpleProxyServlet</servlet-name>
  <url-pattern>/proxy/*</url-pattern>
  </servlet-mapping>
  <context-param>
  <param-name>com.sap.ui5.proxy.REMOTE_LOCATION</param-name>
  <param-value>http://xxxx.atosorigin-ica.com</param-value>
  </context-param>

do I have to do something more?

You also need to add the port

<param-value>http://xxxx.atosorigin-ica.com:XXXX</param-value>

Hi Mathew,

I found the problem.

I have to change the pad in the "Component-preload.js":

now it works.

Hi Andy,

Make an entry of your application in app.config file in your Eclipse environment and try to access your application.

Hi,

the config file looks like this:

{

"applications" : {

             "CRM_MYCONT-display" : {

                "additionalInformation" : "SAPUI5.Component=cus.crm.mycontacts",

                "applicationType" : "URL",

                "url" : "/CRM_MYCONT",

                "description" : "My Contacts"

            }

    }

}

Hi,

Where can I find the app.config file?

Or do you mean fioriSandboxConfig.json?

Hi Andy,

After deploying the extended app to the ABAP repository, go to SE80, select your BSP (corresponding to the extended app) and check if the Component.js file is visible.

Also can you post screen shots of your launchpad in LPD_CUST and the tile and target mapping properties from launchpad designer?

Hi,

I am running the application local on a tomcat server (Version 8).
