Calling Solr requests from java code - examples?
Hi,
Could someone give me some code examples on how Solr requests can be
called by Java code. I'm new to Java and I'm not very sure on how URLs
+ params can be called from java code and how the responses can be
captured. Or what th best practices are?
Grtz

Right, I should have mentioned this one as well. I have linked SOLR-20
and SOLR-86 now, so that people can see the various options for Java
clients.

The javax.servlet.RequestDispatcher interface allows you to access
other resources (including servlets) running in the same container.
I've never used it but it looks like what you'd need (including a
custom HttpServletResponse class to capture the other servlet's
output).
See http://java.sun.com/j2ee/1.4/docs/tutorial/doc/Servlets9.html#wp64684
which is part of
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/index.html
Depending on how much faster this is than going the http way, it might
be interesting to include it as another protocol in a Java Solr
client.

A newbie question on the same topic:
What about the case where solr and my application are deployed in the
same instance of say tomcat. Is there a way to skip the http requests
and use a direct api?
Regards,
Pavel

Doesn't make much difference if your client is a standalone or a web
application: you Solr client class will need to be configured with the
base URL of the Solr server, it will make HTTP requests to it and
parse the results as needed.

Thanks!
and how would you do it calling it from another web application, let's
say from a servlet or so? I need to do some stuff in my web java code,
then call the Solr service and do some more stuff afterwards

Although our Java client landscape is still a bit fuzzy (there are
several variants floating around), you might want to look at the code
found in http://issues.apache.org/jira/browse/SOLR-20
If you're new to Java, I'd recommend playing with HttpClient first
(http://jakarta.apache.org/commons/httpclient/), see the tutorial
there for the basics.
The standard Java library classes are also usable to write HTTP
clients, but HttpClient will help a lot in getting the "details"
right, if you don't mind depending on that library.
