Cannot import XML with permission denied

Not sure if this is the correct forum to ask this question.

We are using EBS version 12.1.3

Our developer get permission error when try to import java.

 

When importing java file in DEV App Server, it is throwing the below error

 

-bash: cd: /ebs/devapp/apps/tech_st/10.1.3/appsutil/jdk/jre/bin/java: Permission denied

 

So, I have change the permission for the java file in that directory to 777

However, after the permission change, the developer still gets error

 

Calling /ebs/devapp/apps/tech_st/10.1.3/appsutil/jdk/jre/bin/java ...

 

/bin/sh: line 1: /ebs/devapp/apps/tech_st/10.1.3/appsutil/jdk/jre/bin/java: cannot execute [Permission denied]
