The type java io ObjectInputStream cannot be resolved It is indirectly referenced from required class files

Question

I have downloaded Eclipse and tried to create a sample servlet program but I got following error      The type java io ObjectInputStream cannot be resolved  It is indirectly referenced from required  class files   I have configured build path correctly  I am using Java 8 and Apache Tomcat 7 and libraries for both are referenced correctly   Problem is specifically for Java EE only  Ordinarily Java SE projects are running fine

same problem with me  This is not a solution but a workaround  which worked for me  Buildpath- Configure buildpath- Libraries-  Here remove the JRE system library pointing to JRE8 and add JRE system library for JRE7

Reason   Old versions of Tomcat 6 JSP compiler don t seem to be aware of JDK 8 constant pool enhancements - eg  method handles  New code in JDK 8u is using a method handle instead of creating an anonymous class  This will cause the method handle to be listed in the constant pool and the eclipse compiler will choke on this - https   bz apache org bugzilla show bug cgi id 56613

You simply need to upgrade your Tomcat version  to Tomcat 8 0 xx  Java8  lt -  Tomcat8  This is the configuration that I have been using and it has always worked out well

Okay  this question was a year ago but I recently got this problem as well   So what I did      Update tomcat 7 to tomcat 8  Update to the latest java  java 1 8 0 141   Update the JRE System Library in Project   Properties   Java Build Path   Make sure it has the latest version which in my case is jre1 8 0 141  before it was the previous version jre1 8 0 111    When I did the first two steps it still doesn t remove the error so the last step is important  It didn t automatically change the build path for jre

Using the latest 7 x Tomcat  currently 7 0 69  solved the problem for me    We did also try a workaround in a old eclipse bug  maybe that did it s part to solve the problem  too    https   bugs eclipse org bugs show bug cgi id 67414  Workaround    Window- Preferences- Java- Installed JREs Uncheck selected JRE  Click OK  this step may be optional   Check JRE again

Workaround   Window -  Preferences -  Java -  Installed JREs  select a different JRE  maybe this JDK edition is not suitable       So try this one instead     Problem solved
