Hi,
A synopsis of the issue i was facing ..
Background:-

We are currently running an application on Sunone 6.1 Webserver (SP6) on a HP-UX machine (PA-RISC v11.11). The java version currently used was java 1.4.2 update 12 that was installed along with the webserver installation sometime back.

We are now trying to migrate the java version from 1.4.2 to java 1.5.0 update 13.

As part of this we had done the following

- Downloaded the jdk 1.5.0.13 wrap from the HPUX support site and installed it on the unix box under /opt/java1.5

- Once the install was successfully done; using the sunone Admin Console changed the following property

Administration Server --> <Server instance> --> Java Tab --> JVM General --> JAVA Home property Old value = /opt_dev/sunone/bin/https/jdk New value = /opt/java 1.5

- Applied the changes and restarted the server

Issue:-
While trying to launch the application the following is shown in the error logs and the server displays a page cannot be displayed error.

****** error Logs *******

******************************


The first page HTML is rendered using a servlet and after putting in logs in this servelet found that this occurs when the DB connection is being established.

public synchronized static Connection getConnection(String serverpath)

throws SQLException, ClassNotFoundException, IOException {



/* Establish connection */

if (!dburl.equals("") && !uid.equals("") && !pwd.equals("")) {



System.out.println("Test Connection **** 21");



Class.forName(driver); // explicitly loads JDBC drivers

System.out.println("Test Connection **** 22");

try {

result = DriverManager.getConnection(dburl, uid, pwd);

} catch (RuntimeException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

System.out.println("Test Connection **** 23");



}



}



*************************************



The error is thrown at this line exactly



result = DriverManager.getConnection(dburl, uid, pwd);





Hence

- Can anyone give me any information on why this error may be occuring?
- Also can you let me know the steps that I would need to follow for migarting the java version on sunone 6.1 webserver ?
- I dont seem to be able to find the core dumps being created after this crash. Can anyone please guide me as to how to enable the dump files creation.

Any info would be helpful

I probably can't help you much, but perhaps the third party library that you are using for your database connectivity is not compatible with the newer version of the JDK.

Cheers,

Finally got the solution.

Did the following steps to solve it .

1.Install the JDK 1.5.0_13 wrap from HP Unix site
jdk15_15013_pa.depot
Site:- http://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=HPUXJDKJRE50

2.Install the java 1.5.0_13 patches from HP-UX
Patch Names:-
- PHCO_35743
- PHKL_34534
- PHSS_37517

Site:- http://h18012.www1.hp.com/java/patches/index.html>

3.Install the Sunone 6.1 SP9 installation (English Version https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_SMI-Site/en_US/-/USD/ViewProductDetail-Start?ProductRef=SJWS-6.1-SP9-OTH-G-F@CDS-CDS_SMI ) and when the installer asks for a path for installation give the same path as where the current SunOne server is installed (/opt/sunone) . In this case the installer performs an upgrade on the existing server instance from Sunone 6.1 SP6 to Sunone 6.1 SP9.

4.update the rt.jar and ojdbc.jar ? [Not sure if this step is required. Better not to do it initially, and in case any problem occurs then consider doing it.]


5.Change the server configurations in the server instance and the admin server instance
Changes required to make the Sunone Server 6.1 run with JDK 1.5

Part I:- Change the entries of WebServer6.1\https-admserv\config\Server.xml

a) Add to the "serverclasspath" variable "crimson.jar" required for the server to run.
The "JVMOPTIONS" important is to be as follows.
<JVMOPTIONS>-Dorg.xml.sax.parser=org.xml.sax.helpers.XMLReaderAdapter</JVMOPTIONS>
<JVMOPTIONS>-Dorg.xml.sax.driver=org.apache.crimson.parser.XMLReaderImpl</JVMOPTIONS>
<JVMOPTIONS>-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl</JVMOPTIONS>
b) The Java tag should have a "javahome="/opt/java1.5"" attribute set.

Part II:- Change the entries in the WebServer6.1\<<local System or Server Name>>\config\server.xml
a) Add to the "serverclasspath" variable "crimson.jar" required for the server to run.
The "JVMOPTIONS" important is to be as follows.
<JVMOPTIONS>-Dorg.xml.sax.parser=org.xml.sax.helpers.XMLReaderAdapter</JVMOPTIONS>
<JVMOPTIONS>-Dorg.xml.sax.driver=org.apache.crimson.parser.XMLReaderImpl</JVMOPTIONS>
<JVMOPTIONS>-Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl</JVMOPTIONS>
b) The Java tag should have a "javahome="D:/Softwares/Java/jdk1.5.0_11"" attribute set.

3.) Add the "crimson.jar" to WebServer6.1\bin\https\jar
