JSON object fails to load in Tomcat BIRT Report viewer

jkamaraj

<p>Hello,</p>
<p> </p>
<p>The following code in Report designer works fine and generated the report</p>
<p> </p>
<div>//Import the packages needed to open the JSON Dataset</div>
<div>importPackage(Packages.org.apache.commons.io);</div>
<div>importPackage( Packages.examples );</div>
<div> </div>
<div>jd = GetAJsonDiv(); </div>
<div> </div>
<div>div633 = "No";</div>
<div>div538 = "No";</div>
<div>div182 = "No";</div>
<div>div181 = "No";</div>
<div> </div>
<div> </div>
<div>if ( divArray[0] == "633" || divArray[1] == "633" || divArray[2] == "633")</div>
<div>{</div>
<div> </div>
<div> </div>
<div>//Get the data for division 633</div>
<div>//**START</div>
<div>input =  jd.sendGet("<a data-ipb='nomediaparse' href='https://mySite/ClaimDeskWeb/services/v1/reportSearch/InjuryByDivisionReport/633'>https://mySite/ClaimDeskWeb/services/v1/reportSearch/InjuryByDivisionReport/633");</a></div&gt;
<div> </div>
<div>//Store the contents in to a variable</div>
<div>jsondata = input;</div>
<div> </div>
<div>//Convert the String to JSON Object</div>
<div>myJSONObject =JSON.parse(input);</div>
<div>len = myJSONObject.length;</div>
<div> </div>
<div>//Counter</div>
<div>count1 = 0;</div>
<div>div633 = "Yes"</div>
<div> </div>
<div>The same code when run in Tomcat Report viewer, report fails to generate and I see the following error in logs:</div>
<div> </div>
<div> </div>
<div>
<div><a data-ipb='nomediaparse' href='https://enterprise.claimdesk.com/ClaimDeskWeb/services/v1/reportSearch/InjuryTypeReport/181'>https://enterprise.claimdesk.com/ClaimDeskWeb/services/v1/reportSearch/InjuryTypeReport/181");</a></div&gt;
<div> </div>
<div>//Convert the String to JSON Object</div>
<div>myJSONObject7 =JSON.parse(input7);</div>
<div>len7 = myJSONObject7.length;</div>
<div> </div>
<div>//Counter</div>
<div>count8 = 0;</div>
<div>div181 = "Yes"</div>
<div>}</div>
<div>//**END</div>
<div> + "</div>

<p>I think JSON is a Java script object. How can I get this to run in Tomcat.</p>
<p> </p>
<p>Thank you.</p>

<p>I recently replied in this thread about JSON support in Eclipse @ <a data-ipb='nomediaparse' href='http://developer.actuate.com/community/forum/index.php?/topic/38962-need-to-create-dynamic-number-of-images-in-masterpage-header/?p=142808'>http://developer.actuate.com/community/forum/index.php?/topic/38962-need-to-create-dynamic-number-of-images-in-masterpage-header/?p=142808</a></p&gt;

<p style="margin-left:40px;"><em>If you are using BIRT 4.5.0, it has built-in JSON support so you don't need the helper JavaScript file, "json.js", in the root of your project folder.  The difference between the two designs in the ZIP is that the one for pre-BIRT 4.5.0, there is an external Resources reference to "json.js", and the one for 4.5.0 does not have it.  If you don't have it in pre-BIRT 4.5.0, when attempting to run the report, you will see an error like ... <strong>ReferenceError: "JSON" is not defined.</strong></em></p>
<p> </p>
<p> </p>
<p>What version of BIRT Designer are you using?</p>
<p> </p>
<p>What version of the BIRT Engine are you running in Tomcat?  If less than 4.5.0, then do you have "json.js" available in your "resources" directory?</p>
