HFEJB - compiling advice guy

[Brad Strausbaugh]

Hello, Everyone.

I just started HFEJB and I'm all the way to page 30. That's where, after having j2ee1.3 installed, you're supposed to compile the Advice Guy application. But when I compile, I get a bunch of errors, all of which complaining that it can't resolve symbols -- package names and interface names and such. It's as though I have something wrong with my PATH. I have my SETs and PATH set up like this ...

SET J2EE_HOME=c:\j2sdkee1.3
SET JAVA_HOME=c:\Program Files\Java\jdk1.5.0_07
PATH C:\WINDOWS\system32;C:\WINDOWS;C:\System32\Wbem;
c:\j2sdkee1.3\bin;c:\Program Files\Java\jdk1.5.0_07\bin

... (without the CR in the PATH line). I double checked and these are the correct directory names. And a c:>SET reveals that the environmental variables are being set correctly. Same with c:>PATH.

I know it's not a typo in the source code because I downloaded the source code from wickedlysmart.com.

I know this will turn out to be some simple needle-in-a-haystack thing, but I can't for the life of me see what I'm doing wrong. Does anything obvious jump out?

Hi Brad,

you have to set some environment variables. Look beneath how it's done (I hope the screenshots speak for themselfs):





The last step is critical, you have to update your PATH environment variable just as shown above.

Because of the last step you can now start j2ee -verbose from whereever you are, you don't have to start it from your %J2EE_HOME%\bin directory. Just make sure that you open a new command shell after you updated all your environment variables to get access to all these new/updated environment variables.

You are ready now for a round trip: compilation - server start - client start
Compile:


Start Server:


Start Client:


That's it ,
Good Luck,
Darya

Hello, Darya.

Thanks for your response to my message.

I'm sad to report that did not do the trick. But you did open my eyes to the fact that I've been setting my environmental variables and path locally (with a .bat file) as opposed to globally. I'm setting them globally now the way you described. Path too. But alas it's still not working, the little dickens.

I'm trying the simple baby step that appears on HFEJB p30

%cd ~/projects/advice/src
%javac -d ../classes headfirst/*.java

... substituting Windows syntax, of course. And this is where it's complaining that it can't resolve package names and interface names etc. BTW, I am running Window XP Home Edition but I'm assuming that would not be a factor since j2se works just fine.

Here is how my environmental variables and path are set ...

This is making me nuts.

Anyway, thanks again for your last reply.

Can you post your command lines you use for compilation, server and client?

[Brad Strausbaugh]

Hello, Darya.

These are my commands for compiling the HFEJB Advice Guy bean (see p30).

C>cd c:\BackupBundle\EJBWorld\Stuff01\projects\advice\src
C>javac -d ../classes headfirst/*.java

... and then the diagnostics appear from the AdviceBean.java source file about the unresolved symbols.

The book hasn't reach the point of launching the server yet, but when I try to do that as instructed on p31... it goes like this ...

C>cd c:\BackupBundle\EJBWorld\Stuff01\projects\advice
C>j2ee -verbose
'C:\Program' is not recognized as an internal or external command operable program or batch file.

So launching the server fails also.

My environmental variables are set as they were in my last post, except that a did correct one typo ...

JSEE_HOME=c:\j2sdkee1.3

is now

J2EE_HOME=C:\j2sdkee1.3

Although that was an error, it seems not to be the issue here as my failure to compile and launch the server remains the same.

Thanks again for your time, Darya.

Hi Brad,

I miss the classpath in your call. Look the example I gave you (the yellow one )

Regards,
Darya

[Darya Akbari]

Take care of spaces (between classes and headfirst) in your path. Put those paths in double quotes or use an underscore.

That didn't matter because you never used it in your command line as classpath . Look how I used them in the given examples (the yellow and green ones).

[Brad Strausbaugh]

Hello, Darya.

Thanks for your last reply.

I added %J2EE_JARS% to my environmental variables, then followed your "yellow" example and that did the trick for compiling. I was able to compile the source files into ~/advice/classes/headfirst/Advice*.class. I should have read your first message more carefully.

But I'm still having trouble launching the server. When I go to your "blue" example, instead of the server launching, it goes something like this ...

C>cd
C:\BackupBundle\EJBWorld\Stuff01\projects\advice

C>j2ee -verbose
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

Somewhere it's associating "j2ee" with "C:\Program" but I don't know where it would be finding that association. It does not appear in my environmental variables. Here are my environmental variables and path. I've add quotation marks to my Path string.

Can you check your folder and look for the j2ee batch file?

[Brad Strausbaugh]

Hello, Darya.

Yes, I have the j2ee batch file in the bin folder you pointed to. BTW, the j2ee install package created a C:\j2ee1.3.1 directory and that's where the \bin and other folders are. Mine is not the "...\J2EE\1.3.1..." like in your screenshot. I also perused the j2ee.bat file (didn't change a thing) and it looks like it should run okay unless I missed something.

Separately, I found that by changing my J2SE_HOME and JAVA_HOME environmental variables from C:\Program Files\... to C:\PROGRA~1\... , I can then at invoke the server, but not without a new cavalcade of errors. Here is a cut-and-past from my DOS shell session...

I'm kinda running out of straws to grasp.

Try it with JDK 1.4.2

[Rahul Toaikani]

See if this thread helps.

[Brad Strausbaugh]

Hello, Rahul and Darya.

Got it!!!

The problem was that my installed J2SE was version 1.5. and appearantly this has some kind of bug that makes J2EE hicup. Sun, bless their hearts, sees no reason to trouble programmers with this information. So the remedy was to download and install j2ee v1.4, adjust environmental variables, etc, and badda-bing, everything works. Life can be beautiful.

So thanks to you both. Darya, you open my eyes to the environmental variable stuff, and Rahul, that thread you turned me on to is where I learned about the J2SE1.5 issue. So I own each of you a beer... or three.

Happiness and Joy, -Brad

Hi Brad,

I'm glad that it worked out. Did you really meant j2ee v1.4 or was it maybe j2se v1.4 .



Regards,
Darya

[Brad Strausbaugh]

I meant j2se 1.4, Darya. Thanks again.
