Can't Build Reports Using MongoDB On Windows 8

Using iReport 5.1.0 and iReport 5.2.0 on Windows 8, I am able to successfully connect to a MongoDB instance, but iReport is unable to query the database.

When I use iReport 5.1.0 on Ubuntu, I am able to connect to and query the database.

Does anyone have any thoughts on why this might be?  Could this be related to the Java Virtual Machine I'm using?

On Ubuntu I'm using an opensource JVM, but on windows I'm using the latest Oracle SDK.

1 Answer:

Can you connect to mongo from your windows box outside iReport?

since you are able to do everything from your Ubuntu box, I'm thinking that it may be a firewall issue or an antivirus preventing you to access port 27017

I can connect to MongoDB on Windows just fine.

What are you using to connect to mongo form Windows, the command line utility or another utility like UMongo ?

Also can you check what error is iReport showing and post the IDE log of iReport (once you get the connection error go to the VIEW menue and select IDE LOG) that will show you the full stack trace and will give you more information.

Here is an example of a failed connection (I used a diferent port)

WARNING [com.mongodb.tcp]: Exception determining maxBSON size using0 couldn't connect to [Mariano-MacBook-Pro.local/] Connection refused
