Hi all,
i have a Solr instance running under tomcat 5.5. My application uses a java
servlet to handle data. I have a problem with "add-update" process: at the
first run the add process is ok and very fast . At this first run i add
around 2.000 docs. Then i commit and all is ok.
The problem is that if i run the same the "add - update" process again,
sometimes (not all the times) it fails with this error:
13-nov-2007 8.17.32 org.apache.solr.handler.XmlUpdateRequestHandler update

The code i'm using for sending the post command for adding docs is the
following:
private String sendPostCommand(String command, String url)
throws IOException {
StringBuffer results = null;
HttpClient client = new HttpClient();
PostMethod post = new PostMethod(url);
RequestEntity re = new StringRequestEntity(command, "text/xml",
"UTF-8");
post.setRequestEntity(re);
try {
// Execute the method.
int statusCode = client.executeMethod(post);
if (statusCode != HttpStatus.SC_OK) {
System.err.println("Method failed: " +
post.getStatusLine());
}
InputStream responseBody =
post.getResponseBodyAsStream();
DataInputStream din = new DataInputStream(responseBody);
results = new StringBuffer();
String line = null;
BufferedReader br = new BufferedReader(new
InputStreamReader(responseBody,"UTF-8"));
while ((line = br.readLine()) != null) {
results.append(line+"\n");
}
//System.out.println(results);
br.close();
din.close();
responseBody.close();
} catch (HttpException e) {
System.err.println("Fatal protocol violation: " +
e.getMessage());
e.printStackTrace();
} catch (IOException e) {
System.err.println("Fatal transport error: " +
e.getMessage());
e.printStackTrace();
} finally {
// Release the connection.
post.releaseConnection();
}
return results.toString();
}
I was wondering if it's a solr relelated issue or if it depends on tomcat
configuration.
Thanks for help.
