MI Client 7.1 on Laptop throws error

[Former Member]

Dear Team,

I am trying to install MI client on my laptop and get an error,

Connection closed.

Server returned exception:

java.net.ConnectException: Connection refused: connect

When I check the technical details, I get the details as below.

Hi Sandeep,

Check in Program Files/SAP Clients/logfile.log whether Java GUI installation is successful or not.

If it is not installed client cannot launch. Then it is Java GUI issue.

Please let us know Which SP of 7.10 Client, and JRE are used.

Thanks and Regards,

Hi Sandeep,

I have the same issue at the startup of my SAP Mobile Client.

"java.net.ConnectException: Connection refused: connect"

Can you please tell me if and how you have solved the issue?

Thanks in advance and kind regards,

Hello,

from the exception it seems the socket is not accessible. So, apart from following the above steps (killing the services n all),

you can also check your firewall settings. Many a times some of the socket access is suppressed by firewall settings.

Please make sure sockets 55103, 55104 are not blocked. Or you can disable your firewall and try launching the client

Best regards

HI Sandeep,

Please go to the services running on your system. (services.msc from run).

Check for the status of maxdb service (of your instance). Is it in started status ?

If it is not started or is in starting state , try stopping and starting it.

Then try starting the client.

Just check if this solves your problem.

Also mention the version of maxdb used.

Thanks,

Hi Sandeep,

Can you please mention the steps when it is throwing this error?

Which DB is used?

After the client installation, if you start the client in the SAP NW Mobile client folder check whether Mobile Lock and Monitor Lock are available. If both are available then the client will start.

If any one of the lock is there, follow these steps:

1. Click on stopmonitor.bat (Kills the Monitor Lock)

2. click on shudown.bat (Kills Mobile Lock)

And perform the below mentioned steps.

If no locks are available, then follow these steps:

1. Click on startserver.bat (Creates Mobile Lock)

2. Click on startmonitor.bat (Creates Monitor Lock)

3. click on startup.bat

Then the client should start.

Even after this if client is not launching, please raise an OSS message.

Thanks and Regards,

Suma,

Followed the steps you had mentioned. It now says " Starting GUI for Java". Connecting... and comes up with the message I mentioned above.

Note: Using MaxDB as the DB.

I had thought that it could be because SAP GUI for Java is not installed, installed the same and tried, still no go.
