Web and WebWorks Development

[Saeger]

Hello there guys,

I noticed that there's a zxing library on OS 6, packages com.google.zxing.*

I would like to know if it's implemented the javascript plugin or i need to do it by myself like using phonegap or something like that ?

Or if it's implemented the javascript caller for the zxing, where do i found the documentation ?

Hi Márcio,

There's an implementation on this in the community APIs repo - https://github.com/blackberry/WebWorks-Community-APIs/tree/master/Smartphone/Barcode

Hello jeff,

Thanks for helping me.
I'm still little confusing here. See:

I copied the content of webworks to
E:\Research In Motion\BlackBerry WebWorks SDK 2.2.0.15\ext\webworks.media.barcode\
And put the <feature> tag in my config.xml to include it into my project.
I created the index.html with the content provided in the sample. when i run the bbwp, i get this error:

E:\Research In Motion\BlackBerry WebWorks SDK 2.2.0.15>bbwp C:\Desenvolvimento\B
lackberry\bb_workspace_webworks\BlackBerryTestes\build\BlackBerryTestes.zip /o C:\Desenvolvimento\Blackberry\bb_workspace_webworks\BlackBerryTestes\build

E:\Research In Motion\BlackBerry WebWorks SDK 2.2.0.15>

Summay: i'm trying to run a sample code using it but i'm little lost here.

Content of E:\Research In Motion\BlackBerry WebWorks SDK 2.2.0.15\ext\webworks.media.barcode\library.xml :

<?xml version="1.0" encoding="utf-8"?>
<library>
  <extension>
    <entryClass>webworks.media.barcode.BarcodeExtension</entryClass>
  </extension>
  <features>
	<feature id="webworks.media.barcode" version="1.0.0.0"/>
  </features>
</library>

Sorry Marco, the fix is in a pull request that hasn't been merged yet.

Please us this library.xml

<?xml version="1.0" encoding="utf-8"?>
<library>
  <extension id="webworks.media.barcode">
    <entryClass>webworks.media.barcode.BarcodeExtension</entryClass>
  </extension>
  <platforms>
    <platform value="JAVA">
      <target version="default" config="JAVA" />
    </platform>
  </platforms>
  <configurations>
    <configuration name="JAVA" version="1.0" >
      <src type="text/java" path="webworks" comment="API implementation in Java" />
    </configuration>
  </configurations>    
  <features>
    <feature id="webworks.media.barcode" version="1.0.0.0"/>
  </features>
</library>

 Perhaps it's already defined in SDK 2.2.0.15 ??

[Saeger]

Sorry,

that was my fault.

defined twice: in the project and in the sdk folder.

Problem solved!
