Oc4jDcmServlet : java.io.IOException: Error writing to server

I've been using the following ant task to do a remote deployment to an OC4J container :
<tasks>
<java jar="../../../../../MAVEN-WORK/portal-lib/oc4j_remote_deploy.jar" fork="yes" maxmemory ="512m">
<jvmarg value="-Djava.protocol.handler.pkgs=HTTPClient"/>
<arg value="http://wblv-ep-sp05:1824/Oc4jDcmServletAPI/"/>
<arg value="ias_admin"/>
<arg value="admin_dev3"/>
<arg value="redeploy"/>
<arg value="/app/oracle/product/oc4jext10.1.2-d3"/>
<arg value="../portal-ear/target/portal.ear"/>
<arg value="portal"/>
<arg value="OC4J_portal"/>
</java>
</tasks>
This has worked before , but I'm suddenly getting error when trying to run it .The error message and stack trace are shown below :

It seems to stall at the "Sending command to DCM servlet" stage , then fails.
Does the DCM servlet write out logs that I can look at?Where is the Oc4jDcmServlet.ear located in an OC4J container directory hierarchy?How do I redeploy the Oc4jDcmServlet.ear ?
This was working a few hours ago as seen here in my previous logs (and I do not understand what could have gone wrong) :

Java.io.IOException: Error writing to server after installing SP17

After installing SP17 in production, we are seeing message in AE failing with com.sap.aii.af.ra.ms.api.RecoverableException: java.io.IOException: Error writing to server.
The messages don't make it to IS and are stuck in AE.
We've checked pipeline url / sm59 entry for INTEGRATION_DIRECTORY_HMI using user - XIISUSER, we did a full cache refresh.
They all appear to be set correctly.
We'll take any ideas and suggestions.
Thank you.

Yes...we have been working all night on this. The FM did create an entry but it does no look like its recognising.
This is what we see in the Adapter messaging tool.

I think it is going through SSL handshake which implemented in HTTP protocol in J2ME.
I have already done the proxy setup and authentication in Sun Wireless toolkit > preferences > Network configuration.
Still error is there. Please help me regarding this, not able to go ahead and rest in peace.

Hi,
have you checked proxy settings in WTK preferences?

RemoteException: 111 java.rmi.ServerError: Error occurred in server thread

Hi,
I'm just new to the RMI field of JAVA. I'm trying to write a program that import the math.jar file in the server side. And the client end can invoke the methods of math.jar and get the value.
I got the error messages as below:
RemoteException: 111 java.rmi.ServerError: Error occurred in server thread; nested exception is:
java.lang.NoClassDefFoundError: org/mathwhizz/Heron
It can work well if I use source classes(*.class) directly instead of importing math.jar. The failure only happened when I try to make use of jar file. Thus I guess my setup and configuration should be ok. Is there anything I should be very careful if I try to run RMI and import a jar file in the program of server side ?
Do I need to use JNLP and web start application in this issue?
I'm appreciated for your responses...thanks...
Sincerely,
Brandon

Java.io.IOException: Error in encoded stream: needed 4 valid base64 charact

Hi All,

Even though I set

Java version i am using is Java 1.4.2
any help would be appreciated
Thanks,

You're probably using an older version of JavaMail. The property was
added in JavaMail 1.3.2

Java.io.IOException during large file processing on PI 7.1

Hello Colleagues,
for a large file scenario on our PI 7.1 System we have to verify with big file size we are able to process over PI.
During handing over the large file (200 MB XML) form the Adapter Frame Work (File Adapter) to the Integration Engine we receive following error:
Transmitting the message to endpoint http://<host>:<port>/sap/xi/engine?type=entry using connection File_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: Error transmitting the message over HTTP. Reason: java.io.IOException: Error writing to server.
The message processing stopped and message still lies at Adapter Frame Work. Large files up to 100 MB we are able to process successfully.
Please, could you tell me why this happened and how we are able to solve it?
Because there is not a java.outofmemory exception however a IO exception i think it could be an memory issue?!
Many thanks in advance!
Regards,
Jochen

Hi Jochen,
Indeed the error is IO Error and it is because the Adapter engine was not able to send the message to Integration server. But it happens due to memory/heap size issues.
Look at these thread, they are having the same problem. Please try the remedy measures suggested by them
Mail to Proxy scenario with attachment. AF channel error.

Attempt to process file failed with java.io.IOException

Hi,
The scenario is from Idoc to flat file and messages are getting processed successfully in XI. but in receiver communication channel error is coming:
Attempt to process file failed with java.io.IOException: Error during STOR/APPE epilogue: com.sap.aii.adapter.file.ftp.FTPEx: 426 Connection closed; transfer aborted.

Hi,
If you are using FTP then,
1. Make sure that the FTP sever does not have issues with Firewall or a Proxy server access.
2. Also verify that the specified FTP user ID has the necessary WRITE or overwrite authorization?

Cannot run program "keytool": java.io.IOException

Hi,
I would like to follow the procedure to change the master password
of glassfish server hosting APEX listener
using the change-master-password subcommand, but the utility keytool
is not found:
glassfish@ahost:/opt/glassfish3/glassfish/domains/mydom01/config> /opt/glassfish3/bin/asadmin
/opt/glassfish3/bin/asadmin
Use "exit" to exit and "help" for online help.
asadmin> change-master-password mydom01
Enter the current master password> changeit
Enter the new master password> changedit
Enter the new master password again> changedit
Cannot run program "keytool": java.io.IOException: error=2, No such file or directory
Command change-master-password failed.
asadmin>
Command multimode failed.
glassfish@ahost:/opt/glassfish3/glassfish/domains/mydom01/config> which java
/usr/bin/java
glassfish@ahost:/opt/glassfish3/glassfish/domains/mydom01/config>
All of glassfish is running fine apart from this.
keytool could be found in /usr/java/latest/bin/keytool.
Do we need to have this in the path? There is no requirement in the
install guide for this, nor did the RPM installation adjust the system
path accordingly.
Hopefully someone can tell my how things ought to be regarding keytool?
Thanks, Tom

Hi Tom,
the procedure to change the master password of glassfish server hosting APEX listener... sounds more like a GlassFish-related topic to me. I guess you'd get the best answers for such questions in a GlassFish-related forum...
For what it's worth, I'll try my best anyway:
Cannot run program "keytool": java.io.IOException: error=2, No such file or directoryThis seems to be a pretty clear error message: keytool , which is probably used to manage the keys for GlassFish users, wasn't found. This means, you're either running on an OS that is not officially certified for GlassFish, or you GlassFish hasn't been configured properly.
You ran
glassfish@ahost:/opt/glassfish3/glassfish/domains/mydom01/config> which java
/usr/bin/java... which indicates you assume your GlassFish is running without JAVA_HOME being set. If that's true, I'd begin to setup you GlassFish properly starting with that parameter.
Anyway, you also found out that
keytool could be found in /usr/java/latest/bin/keytool.... which is not +/usr/bin+ and hence probably not in the global search path of the user on whose behalf your GlassFish is running. So, you could either create a link-set[*] for +/usr/bin/keytool+ to (finally) point to +/usr/java/latest/bin/keytool+, or you setup JAVA_HOME to be +/usr/java/latest+ .
[*] Note that depending on your OS there might be more than one stage of indirection, e.g. my Ubuntu has +/usr/bin/java+ pointing to +/etc/alternatives/java+ which is pointing to +/usr/lib/jvm/java-6-sun/jre/bin/java+ where +/usr/lib/jvm/java-6-sun/+ is pointing to the directory containing the actual JDK to be used. You'll probably find something like that on your system as well. My Ubuntu box has a link for +/usr/bin/keytool+, so I get that when running "which keytool".
Do we need to have this in the path? There is no requirement in the install guide for this, nor did the RPM installation adjust the system path accordingly.Again, this is not a GlassFish forum.
I hope my hints help you solve your problem. If they don't, please choose the appropriate forum for your next post on that topic. And I guess, giving some more information on your OS and how you manage your JDK (and which version you use) will help people there to help you.
Thanks,
Udo

No, and this is not the Hudson forums either. But see this error?

Keystore java.io.IOException

Hi all, when i try to generate a secretkey and store it in a keystore, but i get an io exception for some reason.
it says:
Exception in thread "main" java.security.KeyStoreException: java.io.IOException:
Error initialising store of key store.
i really don't know what i'm doing wrong, a little bit of help would be usefull
this is a piece of my code:
private static String FILENAME = "keystore.ks";
private void registerUserKey(char[] password) throws Exception{
          // Generate secret key for HMACRIPEMD160
          KeyGenerator kg = KeyGenerator.getInstance("HMACRIPEMD160");
          SecretKey sk = kg.generateKey();
          // Create a keystore and place the key in it
          // I use an UBER keystore, which is provided by Bouncycastle.
          KeyStore keyStore = KeyStore.getInstance("UBER");
          keyStore.load(null, null);
          String alias = "exampleKey";
          keyStore.setKeyEntry(alias, sk, password, null);
          FileOutputStream fos = new FileOutputStream(FILENAME);
          keyStore.store(fos, password);
          fos.close();
     }

my days of wandering forums of all kind have finally paid off.
seems like adding the specific classpath option solves my problems
so now i run and compile my files with this line
java -Xbootclasspath:c:\jdk1.2.2\jre\lib\ext\jce-jdk12-118.jar;c:\jdk1.2.2\jr
e\lib\rt.jar; myfilename
and it works fine.
if there is anybody who can tell me why it doesn't work when i change my classpath (and class), that would be hugely appreciated.
But at least now i can run my applications
