Error invoking the entity bean in BMP

[sjagga]

Hello,

I am new to the JBOSS world, I have been trying to test a BMP entity bean and wrote a simple code that should fetch records from mySQL database. When I call the bean after creating it using a finder method I am getting the following error. Can somebody please help me?

thanks!

You're going to have to supply a bit more information. It looks like something is happening at 'loginBean.java:266' (loginBean.setEntityContext(). What's happening there?

Thank you for your response. I got that problem because I was playing around with env object and I removed all those statements and I am no longer getting this problem, however I stepped into another issue. Here is the info....from server.log. As you see the find, activate, load all worked fine, when I am calling the get method I get this problem, the code looks like below....in the servlet...
-----------servlet class--------------------------

login beanRemote;
beanRemote = (login) home.findByUserName("admin");
loginPK pk = (loginPK) beanRemote.getPrimaryKey();
login newLogin = null;
newLogin = home.findByPrimaryKey(pk);
out.println("<p align=\"center\"> Message from Security Entity Bean is: " + "Hello " + newLogin.getUserName() + "");

Never mind, I was able to solve that problem as well. I have found out that I had to define the hashCode() and equals() method for my primaryKey class. Wow that was a great catch thanks to Google and somebody came across a similar issue.

Thanks again....

Good to hear you're on your way. I have to admit that I use Xdoclet for code and deployment descriptor. Works great. Never have to worry about missing items in interfaces, value object or PK classes, descriptors, etc.
