Migrating AEM 6.2 site to AEM 6.3

Question

Hi All,I am trying to migrate my site from AEM 6.2 to AEM 6.3 and I get the following error.

The best solution for such issues has been discussed many times in this forum .

6.2 to 6.3 upgrade using fresh instance

Re: Core Project has dependency on javax.inject [0,1) Bundles and imports not getting deployed

As scott has also previously mentioned in the above questions, just create a fresh project fro 6.3 and add one by one your code and debug the issues and solve it . Dumping 6.2 to 6.3 in one shot is not a good idea. Though there is no much changes you might have to do if you are having a fully sightly code , but JSPs and other deprecated items can cause you an issue and this can be debugged only through a systematic step by step analysis.

VeenaVikraman · Answer

One line of your code says the issue is in your libs page.jsp at org.apache.jsp.libs.cq.Page.Page_jsp._jspService(Page_jsp.java:106) . See if you have the compiled classes under var/classes and check for this line number. It might give you an idea. But make sure this error is not caused because of your components.
