Maximo

Hello,

We are on 7.6.1.1 and we send purchase requisitions from MAXIMO to Peoplesoft via MIF (event listener, out bound Q, end point, Custom java handler etc.). The custom handler java class that implements RouterHandler prepares  the xml messages based upon the requirements from the PeopleSoft app and the "sendData" method performs the HTTP Post to PeopleSoft (the relevant code as follows):

Subject: HTTP 403 error from custom java HTTP Handler

Hello,

We are on 7.6.1.1 and we send purchase requisitions from MAXIMO to Peoplesoft via MIF (event listener, out bound Q, end point, Custom java handler etc.). The custom handler java class that implements RouterHandler prepares  the xml messages based upon the requirements from the PeopleSoft app and the "sendData" method performs the HTTP Post to PeopleSoft (the relevant code as follows):

{

HTTPExit exit = getExitInstance();

//PSFSC88HttpExit exit = (PSFSC88HttpExit)getExitInstance();

String url = getUrl();

MicUtil.INTEGRATIONLOGGER.debug("Pankaj original url: " + url);

//Map urlProps = exit.getURLProperties(metaData, data, destinationMap);

Map urlProps = exit.getURLProperties(metaData, newData, endPointPropVals);

if(urlProps != null)

{

MicUtil.INTEGRATIONLOGGER.debug("Pankaj urlProps: " + urlProps.toString());

url = addURLProps(url, urlProps);

}

MicUtil.INTEGRATIONLOGGER.debug("Pankaj url after adding props: " + url);

URL postURL = new URL(url);

if (postURL != null)

MicUtil.INTEGRATIONLOGGER.debug("Pankaj posturl: " + postURL.toString());

con = postURL.openConnection();

con.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");  // i added this code yesterday

int setCntLength = newData.length;

setDefaultRequestProperty(setCntLength);

Map headerProps = exit.getHeaderProperties(metaData, newData, endPointPropVals);

if(headerProps != null)

{

setHeaderProperties(con, headerProps);

MicUtil.INTEGRATIONLOGGER.debug("Pankaj headerProps: " + headerProps.toString());

}

String strNewData = new String(newData, StandardCharsets.UTF_8); // for UTF-8 encoding

if (strNewData != null)

MicUtil.INTEGRATIONLOGGER.debug("Pankaj strNewData: " +strNewData);

outStream = new BufferedOutputStream(con.getOutputStream());

outStream.write(newData);

                    outStream.flush();                          // throws IOException 

Recently we have started observing that the code throws exception by saying

Server returned HTTP response code: 403 for URL: https://<PSHOSTNAME>/PSIGW/HttpListeningConnector

psdi.util.MXSystemException: BMXAA1477E - The connection failed to the HTTP handler for the endpoint. Review the error and server log flies for information to indicate the cause of the issue, for example, incorrect properties in the DefaultHTTPExit.java handler class.

Server returned HTTP response code: 403 for URL: https://<PSHOSTNAME>PSIGW/HttpListeningConnector

We got the exact same payload  (xml message) by debugging the class and we posted the payload using cURL and Postman and it worked seamlessly without any HTTP error (i.e. response=200). 

Any reasons why the http post could be failing from the java class running from the app server but works fine from cURL and Postman. We have been using this java class for the last decade and it worked fine, but recently having 403 issues.

We also issued the exact same cURL command from the same app server's command prompt and it posted correctly without any error (so no firewall issues)

Any clue? Known issues? 

Thanks
