Connection lost to server using my spark plugin

Hi,

I have the following environment:

  • JRE 1.5.0_06

  • Spark Client 2_5_8 without JRE

  • I implemented the plugin using the JDK 1.5.0_12

Without my Plugin the spark Client runs trouble-free.

But when I use my plugin and restart the spark Client, the server closes the connection to this client in approx. 10 secs after successful login. The openfire server receives a message such as <message id=“KCx-234”></message> and closes the connection due to an error while processing this message.

Upgrading the JRE 1.5.0_06 to the JRE 1.5.0_12 or higher doesn’t solve the problem.

But use of a spark distribution with JRE (1.6.0_01) or upgrading the JRE 1.5.0_06 to 1.6.0_01 solves the problem.

May be that the use of 1.6.0_01 or higher is a requirement to use additional plugins within Spark_2_5_8?

Is there something else to do with my plugin to get working with JRE 1.5.0_xx?

Thanks in advance,

Have you checked your Spark and Openfire error logs.

The Openfire error log file shows an error message: the server closes the connection due to an error while processing a message such as <message id=“KCx-564”></message>

The spark error log file contains no information about any errors regarding this error.

There are 2 levels of spark errors. One in the program’s folder the other is in the users profile folder in a spark folder.

This is the exact error message at openfire side.

Any Idea?

What is your plugin supposed to do? With it installed you are getting a NPE error, meaning a specified required variable is not present.

My Plugin sends at initialize time some XMPP messages from the current user to a specific smack client (agent@domain), which handles this messages.

That means the message should show as follows: <message id=“xxxxx” from=“currentUser@domain” to=“agent@domain”><PacketExtension></PacketExtension></messag e>

BUT: The message received from Openfire shows as follows: <message id=“xxxxx”></message> without from and to attributes.

Therefore the MessageRouter throws an NPE error at MessageRouter.java:183
