Example redirections
See how every redirection is qualified with a "redirectType". If not specified it will pick up the global redirect which may be clent side redirect or server side redirect. Be aware though that one should specify this serve side redirect line very occasionally. You should leave this line unspecified most of the time. This support is added when you have large amounts of data that requires to be repainted. So this is useful in form field validations that carry a lot of data.
request.LoginRequest.classname=com.ai.parts.AspireLoginPart
request.LoginRequest.redirectURL=/{aspireContext}/display?url=welcomePageURL&username={username}
request.LoginRequest.redirectURL.redirectType=serverside
request.LoginRequest.failureRedirectURL.INVALID_PASSWORD=\
/{aspireContext}/display?url=LoginPageURL&pageStatus=invalid-login&vs={viewState}
request.LoginRequest.failureRedirectURL.INVALID_PASSWORD.redirectType=serverside
The order of search for redirection
1. Use the root cause code to locate the redirect url
2. Use a matching pattern in the exception message to identify the redirect url
3. Use the failure redirect url off of the request name irrespective of the exception
4. Use the global failure response page if this is not available
Identifying a redirect url using root cause code
request.requestname.failureRedirectURL.rootcausecode=(your redirection)
Identifying a redirect url using matching pattern
request.requestname.failureRedirectURL.matchStrings=string1|string2|string3
request.requestname.failureRedirectURL.string1=(your redirect url)
request.requestname.failureRedirectURL.string2=(your redirect url)
Using the failure redirect url
request.requestname.failureRedirectURL=(your redirect url)
What is a root cause code
When an exception is thrown, this string indicates the url to which the request should be redirected to. If the root cause message is as follows:
"DUPLICATE_EMPLOYEE_NAME:Hey this is not allowed my good fried"
Then the root casue code is
DUPLICATE_EMPLOYEE_NAME
You can use this for redirection as follows
request.requestName.failureRedirectURL.DUPLICATE_EMPLOYEE_NAME=(your redirect url)
This facility is quite handy when you are using stored procedures to alter the redirection path.
Available parameters when something goes wrong
1. aspire.return_code always indicates "failure"
2. aspire.request_name points to the name of the request that came in
3. aspire.error_message points to the message in the exception
4. aspire.root_cause points to the root cause string of the exception
5. aspire.root_cause_code points to the root cause code if available
Now you can specify redirectType
Starting build 19.x you can do this
request.requestName.failureRedirectURL=(your redirect url)
request.requestName.failureRedirectURL.redirectType=(default|serverside:default)
Reserved words in this context
failureRedirectURL
redirectType
redirectURL
matchStrings
