Hello!

I have trouble with setting up the connection pool for informix database
in netbeans ide 6.0.1
I've found netbeans tutorial which explains how to set up the connection
pool for mysql database. I followed the steps from tutorial,but it
doesn't work for informix database.

I have index.jsp page on which I have drop-down list which should be
filled in with data dynamically.

First error I've received was:
javax.servlet.ServletException: javax.servlet.jsp.JspException: Unable
to get connection, DataSource invalid: "java.sql.SQLException: Error in
allocating a connection. Cause: Class name is wrong or classpath is not
set for: com.informix.jdbc.IfxDataSource"

I've solved this by adding the ifxjdbcx.jar to my project's library.

But, the second error I don't know how to handle:
javax.servlet.ServletException: javax.servlet.jsp.JspException: Unable
to get connection, DataSource invalid: "java.sql.SQLException: Error in
allocating a connection. Cause:
java.lang.StringIndexOutOfBoundsException cannot be cast to
java.sql.SQLException"

This is the part of web.xml file:

<resource-ref>
<description>jdbc:informix-sqli://192.168.242.131:9088/ifxdatabase:INFORMIXSERVER=ifx01</description>
<res-ref-name>jdbc/IfxDatabase</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

And this is the content of sun-resources.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE resources PUBLIC "-//Sun Microsystems, Inc.//DTD Application

<property name="User" value="bpadmin"/>
<property name="Password" value="pass"/>
</jdbc-connection-pool>
</resources>

I can't find what is wrong. I would appreciate very much if someone
could give me any advice. Thanks in advance.

try:


jdbc:informix-sqli://
192.168.242.131:9088:INFORMIXSERVER=ifx01;database =ifxdatabase


Assume that your database is called ifxdatabase

I've tryed
jdbc:informix-sqli://192.168.242.131:9088:INFORMIXSERVER=ifx01;database =ifxdatabase,
as you suggested, instead of
jdbc:informix-sqli://192.168.242.131:9088/ifxdatabase:INFORMIXSERVER=ifx01,
but I'm still receiving the same error:

javax.servlet.ServletException: javax.servlet.jsp.JspException: Unable
to get connection, DataSource invalid: "java.sql.SQLException: Error in
allocating a connection. Cause:
java.lang.StringIndexOutOfBoundsException cannot be cast to
java.sql.SQLException"

Do you have any other suggestion?
Thanks for trying to help me.

hmm not really assume that

User" value="bpadmin"
Password" value="pass"

is correct, can you try this using dbaccess ->> connection--> user
bpadmin -->passwd pass

also did you check if your informix jdbc driver is in your path...

you could goto the examples and see/test if you can get that to
work....

hmmm may be when you try to a onstat -m
you may see error 952 in the log meaning that the user/passwd is not
correct.


this:

Cause:
java.lang.StringIndexOutOfBoundsException cannot be cast to
java.sql.SQLException"

is very weird, sounds like maybe driver not in classpath???

The connection string is correct, I can connect to my database and I've
checked if my informix jdbc driver is in the classpath. Everything is
correct. My SQL query is also correct, so I guess I'm in the blind
street. I really don't know what is wrong, I even don't have any idea
what should I try next.
