Re[2]: Using Xindice inside own code

["Pavel G. Sozonovsky" <pa...@alee.com>]

Hi Catie,

Thank you for your help.

I've tried to use a bit modified code:

String xindicePath = xindiceDir.getCanonicalPath();
String classpath = System.getProperties().getProperty("java.class.path");
String javaHome = System.getProperties().getProperty("java.home");

String startCommand = javaHome + "\\bin\\java.exe -Xms16m -Xmx128m -Dxindice.home=" +
                      xindicePath+" -classpath " + classpath +
                      " org.apache.xindice.server.Xindice " +
                      xindicePath + "\\config\\system.xml";

Process _serverProcess = Runtime.getRuntime().exec(startCommand, new String[0], xindiceDir);
// ...

But I get another error:

LINE IS:
LINE IS: Xindice 1.0 (Birthday)
LINE IS:
LINE IS: Database: 'db' initializing
LINE IS: Script: 'GET' added to script storage
LINE IS: Service: 'db' started
ERROR LINE IS: java.lang.NullPointerException
ERROR LINE IS:   at org.apache.xindice.server.services.SocketServer.createServerSocket(SocketServer.java:242)
ERROR LINE IS:   at org.apache.xindice.server.services.HTTPServer.run(HTTPServer.java:180)
ERROR LINE IS:   at java.lang.Thread.run(Thread.java:484)


Don't you know what is a problem?
Do I anything wrong?

Thanks again.
