Hi, I’m a beginning struts developer and I am trying out myEclipse.
I love the clear flash tutorials, but I have a problem with the Hibernate one.
The java file is looking for some import declarations (i think).
I have a screenshot to show you what i mean:
http://www.xs4all.nl/~ruffie21/hibernate.JPG

So my question is. Is this a real problem e.g. the project won’t run, if so, how do i fix this?

I use Eclipse 3.0.0 (updating to 3.0.1 internally, errors at the updated ant plugin (read timeout)).

What is the error? “Cannot find class”? Try and click CTRL+SHFT+O for Organize Imports and see if they clear up. Also make sure you “Add Hibrenate Capabilities” to your project, and also make sure that all the libraries were added correctly to your build path (Project Properties > java Build Path > Library tab)

Hi there, tnx for the answers.
But I gotta tell you, everything you said to check I did, about adding Hibernate capabilities, done that too (I followed the tutorial).

So I just deleted my whole project and started all over. And now all the errors are gone too. Don’t know exactly how, cuz I didn’t change any settings or so, weird thing.

But I still got a few problems regarding Hibernate and MyEclipse (maybe someone could change my thread title?):

– This has been going on for a couple of days already, but just one day when I wanted to start MyEclipse, it halted said to check the log. I won’t post that yet, cuz I tried the following:
1. Tried to use the update function inside of Eclipse, but that gave a read timeout error at the Ant package.
2. When I start eclipse.exe itself, it works fine (MyEclipse functionality available too). So I downloaded the 3.0.1 release of Eclipse and just overwrote the old installation, but when starting MyEclipse again, still gives me the following error in the log:

So I don’t know what happened. It just suddenly did. And before I blame MyEclipse or install it all over again, just wanted to first find out if this can be fixed.

-Second thing regarding Hibernate. I think i saw this same very problem somewhere here, I haven’t searched yet, so please excuse me if this is already spoken of, I will then search for myself:
I completed a project based on the Hibernate tutorial. Same methods, flow everything, except different database, properties and such of course.
Everything checks out OK when deploying and I get the input form screen, BUT when I hit Submit I get the error that the Hibernate Session is CLOSED.
So what’s up with that?

Sorry for the long post, but I don’t like to open a new thread for every little problem 😉

Eclipse 3.0 requires that you run it with a 1.4 JRE

ubmit I get the error that the Hibernate Session is CLOSED.
So what’s up with that?

This is a common problem when getting started with Hibernate (god knows I’ve done it), you need to be good about opening/closing your sessions at the right time. It sounds like you are inadvertantly trying to use a session, that a few lines of code before you are probably closing. What you can do is figure out where this exception is being thrown and then add a line RIGHT before it to open a new session, the problem will likely go away.

If you want to get good with Hibernate I HIGHLY suggest Hibernate in Action, its a fantastic book written by the authors of Hibernate… it gives you all the in depth details that others may not be aware of, or cover stuff you have always wondered about. It has a particularly good section on explainin what a “Session” is and how to use it.

Tnx, I’ll take a look into that!

Furthermore. I’m running the 1.5.0SDK/JRE here and it worked all fine before as i said. This problem just came all of a sudden. I can run eclipse.exe (or myeclipse that is), but ony with the -vm <path of jvm> parameter. My enviroment variables are all good.
To my understanding this isn’t much of a problem, so I’l just work like this for now.

About Hibernate, it’s very weird then, cause I followed the exact code and everything of the tutorial, and that one works? 😛

Furthermore. I’m running the 1.5.0SDK/JRE here and it worked all fine before as i said.

If you look at the section of code that I quoted, it is showing that Eclipse is running with Java 1.3.1_01, not your 5.0 install. This is likely just a path issue.

I can run eclipse.exe (or myeclipse that is), but ony with the -vm <path of jvm> parameter.

Yes you are exactly right, this is what you need to do in order to run eclipse with multiple JREs installed:

eclipse.exe -vm c:\jdk1.5.0\bin\javaw.exe

About Hibernate, it’s very weird then, cause I followed the exact code and everything of the tutorial, and that one works? 😛

Yes I’m sure it did, but I know that when I was getting started with Hibernate I had this problem ALL the time, I just don’t remember the “golden rule” that I used to avoid it… if you can give me code snippets we can look at it together. First look at where the exception is being thrown, what does that code look like? Does it call any other code? Etc…

[RUFFIE]

I’m currently reading a lot on the Hibernate site, and the developers there said something about Hibernate’s built-in connection pooling is not for production. What do they mean by that? They’re also recommending other things like Proxool, but If they ain’t working (and recommending other things) why make it? There has to be a way to keep the connection open properly right. I really would like to use Hibernate because of it’s ease within the myEclipse enviroment.

Anyways, this is the exception I get:

I’m not putting AddComponent.java nor .jsp here (yet), cause there is no line 120. (I assume the numbers in the exception error are linenumbers?)

}

The only thing I find strange (to me, cuz I’ve got no experience with it yet) is why it has so many finally { …session.close() } functions.

[Riyad Kalla]

The finally close blocks are because Hibernate throws checked exceptions (something I heard Gavin wishes he could change), and the finally clauses are to make sure the session gets closed if any exception is thrown in the try block (for example, open a session, attempt a connection, connection fails, throws an exception… besides the exception you want to make sure your session is closed).

[RUFFIE]

Do you have any other ideas on how this can be fixed or done in another way? I’m still busy with Hibernate docs right now (don’t work on weekends ;)).

[Riyad Kalla]

You mean the session closed exception? I don’t have any other things to try besides what I already suggested, also with respect to your question about connection pooling, for Hibernate they suggest either using your application server’s connection pool, or like you found, another 3rd party pool. The one included with Hibernate is just for testing and getting something working quickly, what they don’t want you to do is deploy a full J2EE app using their connection pool, its not anywhere near as robust or tested as the other 3rd party connection pools, that is what they mean by that warning.

As I’m still unexperienced with all this, can you maybe suggest a few other 3rd party tools, with almost the same functionality (e.g. class/mapping generation and such). Someone pointed me to proxool, I’m looking at it right now, but I’d be very thankful if you could point me to some other alternatives.

You mean persistence engines like Hibernate, or tools for Eclipse that let you work with hibernate? You can try Hibernate Synchronizer plugin, its quite good and a lot of people like it: http://www.binamics.com/hibernatesync/

Someone pointed me to proxool, I’m looking at it right now, but I’d be very thankful if you could point me to some other alternatives.

Proxool is a connection pool not a persistence engine.. its a pluggable part to Hibernate (persistence engine)… I’m not sure I understand your question. Either way, another popular connection pool is the Jakarta Commons DB Connection Pool here: http://jakarta.apache.org/commons/dbcp/

Yes I’m sorry if my question seemed rather vague.
I did mean other tools LIKE Hibernate with almost the same functionalities. The generation and mapping in particular.

I did see that Proxool isn’t really what I’m looking for. I understand it kinda works like a proxy, running transparent to your excisting db pool (something in that matter).

I’ll look at the synchronizer plugin right away, thank you very much.
Other recommendations are surely welcome still.

O yeah and about the original problem, about the hibernate session being closed; someone posted the solution in another topic in this forum as being:

if (session == null || session.isOpen() == false) {....

. You had to put that in the generated SessionFactory class and this wasn’t covered in the tutorial 🙂

And on another note, i convinced my boss to “buy” myeclipse 😀

Ahh, ok the only other one I know of with the same hype level as Hibernate is JDO, its Sun’s ‘official’ version of Hibernate.

And on another note, i convinced my boss to “buy” myeclipse 😀

That’s great, thank you for the support!
