Hi Helen,

In our WO application, we need to call a XML RPC service to get
course data. Since each call will get data only for one course and
we need to update all the courses in our database, so we made a loop.
What classes are you using to access the course data? Are you
waiting for a reply before sending the next request?
Here is my coding:
ISSOXMLClient server = new ISSOXMLClient( url, userid, password);//
when this constructor is called, a object of XmlRpcClientLite is
instantiated.
int c = courses.count();
System.out.println("There are total " + c + " courses.");
for(int i = 0; i<c; i++)
{
Course aCourse = (Course)courses.objectAtIndex(i);
String semester = "";
String isisAbbrev = aCourse.isisAbbrev().lookupCode();
String isisNum = aCourse.isisCourseNum();
System.out.println("Call " + i);
result = server.selectISSOCourseMaster(semester, isisAbbrev,
isisNum);
//Then result is stored in a array.
}
But when the service was called continuously about 30 times, an
exception org.apache.xmlrpc.XmlRpcException: out of threads was
thrown. We have tried many ways to solve the problem but still no
good. We need help. Any ideas or suggestions are welcome!
Can you reuse the threads from the previous requests? It sounds
like it perhaps has a pool of threads that need to be reused or the
pool size needs to be increased.
How to reuse the pool of threads and to increase the size of pool?
