Thread: Need help compiling java class files

Problems such as this usually occur due to the lack of other jar/classes which the imported project depends upon. Just for fun, I quickly imported the Jabble source into my IDE and saw several errors pointing towards a missing library (org.apache...) which comes shipped with the project (log4j). Importing the library erased all errors.

Hi Copeg,

Thanks for your response - it sounds very interesting indeed - I would never have figured that out!

Can you keep me right on what I am doing (I am so new to Java) as I wasn't able to remove the errors?

I am using NetBeans IDE 6.8
I downloaded log4j from here
I booted NetBeans went to Tools / Libraries
I created a new Library (Apache) and the ClassPath and Source to the log4j jar file (log4j-1.2.15)
I went to Run / Clean and Build New Project and I still get a list of errors.

Obviously I am not doing something right - I am not totally computer illiterate but again I am stuck. I was hoping if you could give me a run through of what exactly I should do - maybe emulate your setup?

Thanks again

I took the initiative and googled on how to import libraries into NetBeans...I used this page here. The Jabble project now debugs properly with no errors, however, when I go to Run / Clean and Build the build fails and reports 29 errors.
Is it another case of where I am missing a library.
Here is the error log.
Can someone help me? Thanks

Be aware the OP has cross-posted this to other forums (e.g. CodeGuru).

Hi have a look on your errors. There is a space in every class name like as:

C:\Users\User1\Desktop\Jabble.src\JabbleFinal\Abou tDialog.java:48: not a statement
AboutDialog.1 local1;

It should be AboutDialog.java

I think this is the only error.
