Here is a list of issues you may encounter with Petals ESB but that are not bugs.
These problems may be due to a hardware configuration or to operating system restrictions.

h1. Petals is unreacting or freezed

*Operating system:* Windows (verified on XP and 7)

*Symptoms:*
* The Petals command line does not display anything new anymore.
* The last lines may be a normal log entry or an exception stack trace.
* JMX commands seems without effect. When you execute them (from the JConsole, from the Petals web console), there is no response.
* Other Petals scripts do not change anything. _stop.bat_ and _shutdown.bat_ do not work.

\\
*Solutions to try:*
* Go in the Petals command line, give it the focus and type in _Enter_.

\\
*Explanations:*
You have probably selected something in the DOS shell (e.g. the JMX URL of Petals).

*Operating system:* All

*Symptoms:*

When installing a component or deploying services, I get the following error message:


{code}
The remote resource [http://server:port/context] is not a valid JBI archive: text/htm
{code}
*Explanations:*
If the installed archive is downloaded from Internet and it is needed to download it through a HTTP(s) proxy, perhaps have you forgotten to to configure your HTTP(s) proxy settings.

*Solution:*

Configure your HTTP(s) proxy settings editing the startup script to add your properties as JAVA_OPTS. Available properties to configure your HTTP(s) proxy are listed on the Java documentation: [Java networking and Proxies|http://download.oracle.com/javase/6/docs/technotes/guides/net/proxies.html].
{code}
if [ -z "$JAVA_OPTS" ]; then
JAVA_OPTS="-Xmx1024m -XX:MaxPermSize=256m -Djava.net.preferIPv4Stack=true -Dhttp.proxyHost=proxy.company.com -Dhttp.proxyPort=8080"
