Hello all,
I tried to use the Google AdWords API Java Classes in ColdFusion, but
encountered an error/problem I don't have an answer to yet. Here is what I
did so far.
I started with creating an refresh token and it works without any major
problems.
Afterwards I started to adapt the GetCampaigns Example from Java to
ColdFusion.
Here is the code I use:
function getCampaigns() {
// sure these fixed variables are set to the correct values in my
app... :)
var CLIENT_ID = "";
var CLIENT_SECRET = "";
var REFRESH_TOKEN = "";
var DEVELOPER_TOKEN = "";
var oAuth2Credential = createObject("java",
"com.google.api.ads.common.lib.auth.OfflineCredentials$Builder").init()
.forApi(createObject("java",
"com.google.api.ads.common.lib.auth.OfflineCredentials$Api").ADWORDS)
.withClientSecrets(CLIENT_ID,
CLIENT_SECRET)
.withRefreshToken(REFRESH_TOKEN)
.build()
.generateCredential();
// Construct an AdWordsSession.
var session = createObject("java",
"com.google.api.ads.adwords.lib.client.AdWordsSession$Builder").init()
.withOAuth2Credential(oAuth2Credential)
.withDeveloperToken(DEVELOPER_TOKEN)
.withUserAgent("TimoCom-AdWords-Scheduler") // I
have to set it | I don't know if it matters or not or what else.
.build();
var campaignService = createObject("java",
"com.google.api.ads.adwords.axis.factory.AdWordsServices").init()
.get(session, createObject("java",
"com.google.api.ads.adwords.axis.v201601.cm.CampaignServiceInterface").getClass());
var builder = createObject("java",
"com.google.api.ads.adwords.axis.utils.v201601.SelectorBuilder").init();
var CampaignField = createObject("java",
"com.google.api.ads.adwords.lib.selectorfields.v201601.cm.CampaignField");
// enum
var offset = 0;
var PAGE_SIZE = 100;
var usedCampaignFields =
javaCast("com.google.api.ads.adwords.lib.selectorfields.EntityField[]",
[CampaignField.Id, CampaignField.Name]);
var selector = builder
.fields(usedCampaignFields)
.orderAscBy(CampaignField.Name)
.offset(offset)
.limit(PAGE_SIZE)
.build();
writeDump(var=usedCampaignFields);
writeDump(var=selector);
writeDump(var=campaignService);
If I only use this code it is working, like it should. I get the
dumps(output of public information) of the variables/classes.
But when I try to get the campaigns with the following line, the
application crashes without throwing or logging the error.
var page = campaignService.get(selector).getEntries();
// or simply writeDump(campaignService.get(selector));
The error isn't handled within the onError method in our Application.cfc
nor is it logged in the Coldfusion logs nor in the Catalina Logs of Apache.
Every other Error I got previously was handled by the onError method and I
could see it and adapt my code to have it working, but not this error.
I don't know if I'm doing something wrong or it's an unhandled error in the
AdWords API, in Apache, in ColdFusion, in Java, or what is happening here.
Therefore I hope that one of you can help me.
We're using ColdFusion 9 V9,0,1,274733 on a Linux with Java V1.8.0_71.
