I am trying to save the data in my db (already saving it in lportal). For that i created a connection file and wrote all the required code. Like we do in JDBC. I am able to store the data in lportal(default one) but when I tried to save it in my db. I am getting below exception.
java.lang.ClassNotFoundException: org.postgresql.Driver cannot be found by ""
I tried adding the JAR to the folder but still the same thing. In JDBC we can add the JAR in lib folder but it doesn't seem to work here.
I also tried adding the jar to the tomcat bundle in lib and lib/ext folder but nothing seems to happen.
I also added the following line in my build.gradle file but no results.
compile group: 'org.postgresql', name: 'postgresql', version: '42.2.25'
Can someone help regarding this as where and how to add JAR or any other file so that I can save the data in db at the same time as lportal.

First of all your question is very confusing. So you want to use a PostgreSQL for your Liferay Portal right? You configured everything correctly and downloaded the driver from https://jdbc.postgresql.org/download/postgresql-42.4.1.jar?
Just put this driver in tomcat/lib not ext (maybe it is not configured to load). Restart the server.
Please provide the complete startup log output.
EDIT1:
Ok now I see what is wrong. Your gradle file need to compileInclude instead of compile the lib. The scope compile is only for compilation phase but you also need the library during runtime in the portlet so thats why you need to compileInclude it.
OSGI is a bit tricky when it comes to dependencies because you will get errors after this compileInclude. The portlet will tell you that there are missing dependencies. You can put them to an ignore list.
build.gradle - add line
compileInclude group: 'org.postgresql', name: 'postgresql', version: '42.4.1'
You need to put some packages to not import them in the bnd.bnd file. Just copy the Import-Package part. It needs to be copied in exact this way!
Bundle-Name: test-redirect-jsp
Bundle-SymbolicName: test.redirect.jsp
Bundle-Version: 1.0.0
Export-Package: test.redirect.jsp.constants
Import-Package:\
!com.sun.jna*,\
!org.osgi.service.jdbc*,\
!waffle.windows.auth*,\
*
The driver class should now be available during runtime.
MyTest
public class StaticTest {
public static void test() {
String driver = "org.postgresql.Driver";
try {
Class c = Class.forName(driver);
System.out.println(c.getName());
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Called
@ProcessAction(name = "addOrganization")
public void addOrganization(ActionRequest actionRequest, ActionResponse actionResponse)
throws IOException, PortletException {
StaticTest.test();
}
Please be adviced that my and your solution are very dirty. This is not how it would be done and recommended. The clean way would be setup a second datasource via properties and build your external entities via service builder.
Again - please refer to https://help.liferay.com/hc/en-us/articles/360018160911-Connecting-Service-Builder-to-External-Data-Sources
