After modifying the JSP page, you can package and deploy the page to Tomcat.
One of them is, of course, the index path of the search.
Nutch-site.xml
<Property>
<Name> searcher. dir </Name>
<Value> F:/nutch/test </value>
</Property>
The other part is
Nutch-default.xml
<Property>
<Name> plugin. Folders </Name>
<Value> plugins </value>
<Description> directories where nutch plugins are located. Each
Element may be a relative or absolute path. If absolute, it is used
As is. If relative, It is searched for on the classpath. </description>
</Property>
This is because the path must be modified before the source code can be edited in eclipse.
If you modify these two points, you can use ant to package build. XML in eclipse. Change the package into a jar package to a war package. In this case, OK. If you have any questions about packaging, please contact me by email.
