Fetch data for version A.1 only for EPM Document

prathi · ‎Jun 13, 2016

Hi,

We have written a utility to fetch the URL Drawing of a part created in Creo.

Code Snippet :

final QueryResult qr = PersistenceHelper.manager.find((StatementSpec)qs);

while (qr.hasMoreElements()) {

EPMDocument epmm = (EPMDocument) qr.nextElement();

if ( (epmm.getNumber().endsWith(".drw")) || (epmm.getNumber().endsWith(".DRW")) && (internalUrl != null) && (internalUrl.length() > 0) )

{

Representation defaultRep = RepresentationHelper.service

.getDefaultRepresentation(epmm);

ContentHolder holder;

try {

holder = ContentHelper.service.getContents(defaultRep);

Vector contents = ContentHelper

.getContentListAll(holder);

ApplicationData data = null;

WTProperties propName = WTProperties.getLocalProperties();

String protocol= propName

.getProperty("wt.webserver.protocol");

String rmiHost = propName

.getProperty("wt.rmi.server.hostname");

String portUsed = propName.getProperty("wt.webserver.port");

for (int i = 0; i < contents.size() ; i++) {

if (contents.get(i) instanceof ApplicationData) {

data = (ApplicationData) contents.get(i);

URL aURL = WVSContentHelper.getDownloadURL(

data, holder);

String cURL = null;

String result = null;

if ( aURL.toString().contains("pvs") ){

cURL= aURL.toString();

result = cURL.substring(cURL.indexOf("ContentHolder=")+14, cURL.indexOf("&u8=1"));

String rmiHostName = "&objref=OR%3A";

internalUrl = internalUrl

.substring(

internalUrl.indexOf("createCDialogWindow('") +21,

internalUrl

.indexOf("http:"));

finalURL = protocol + "://" + rmiHost + ":" + portUsed +internalUrl + cURL + rmiHostName + result;

;

break;

It was working fine, but recently we found a limitation. If we revise the Drawing from Windchill and then re run the utility, It shows a Java Array size error.

and so on.

On my investigation, i think that it is because of these multi revisions of drawing, it is failing.I tried using some APIs could not solve this .

Request you to help me solve this.

From stacktrace it seems like error is on below line. Your code does not explain what internalURL is, but it seems like your length of internalURL is less than internalUrl.indexOf("createCDialogWindow('") +21.

internalUrl = internalUrl.substring(internalUrl.indexOf("createCDialogWindow('") +21,internalUrl.indexOf("http:"));

I am not sure if you are getting download URL using WVSContentHelper.getDownloadURL API then why you are constructing new URL finalURL.

Hope it helps!!

Thanks

Hi,

Below are details regarding internalURL.

String javascriptKey = "javascript";

VSResult result2 = UIHelper.getLaunchProductView(partRef,

new Boolean(true), SessionHelper.getLocale());

String internalUrl = (String) ((HashMap<String, Object>) result2

.getObject()).get(javascriptKey);

From WVSContentHelper.getDownloadURL, we are getting multiple URLs. To get the one related to drawing link we are sorting using ".pvs". But the URL obtained here is not sufficient to open the drawing link. So we are adding few terms before and after the URL obtained and thus making a final URL.

The length is not less that the required length. Refer below for reference :

Here DEMOPART 23 does not has the Drawing link revised and hence is called once, but for DEMOPART 21 the Drawing link is revised and hence it is being called twice. If you see the Internal Actual url for DEMOPART 21 is printed only once. so it seems to be same for both revisions.
